This article offers a historical inquiry into behaviorism and its impact on standard of judgement concerning education policies. Drawing from Aldous Huxley’s reservation towards behaviorism as a scientific movement that naturalizes the role of control in human affairs, the paper maps the impact of behaviorism on economics of education. By tracing the influence of behaviorism in both rational (human capital theory) and quasi-rational (behavioral insight) economics, we draw attention to the activity of knowledge-making that describes and prescribes agency. The paper (...) demonstrates how policy instruments and outcomes are intimately linked to assumptions about personhood, and in the case of behavioral insight, they contribute to the scope of decision-making entrusted to government and business. Utilizing a genealogical approach, the paper invites ethical reflections on the long-term implications of behavioral economics in light of automation. (shrink)

Slight absolute changes in the Shanghai Stock Exchange Index (SHSE) corresponded to the city’s immediate increases in coronary heart disease deaths and stroke deaths. Significant fluctuations in the Shenzhen Stock Exchange Index (SZSE) corresponded to the country’s minor, delayed death rates. Investors deal with money, greed, stock volatility, and risky decision-making. Happy people live longer and better. We ask the following question: Who are the investors with the highest and most sustainable stock happiness, and why? Monetary wisdom asserts: Investors apply (...) their deep-rooted values (avaricious love-of-money aspiration and locus of control, Level 2) as a lens to frame critical concerns in the proximal-immediate (Shanghai Stock Exchange Index changes, Level 1) and the omnibus-distal contexts (domicile: city vs. country, Level 2) to maximize expected utility (portfolio changes, Level 1) and ultimate serenity (stock happiness, Level 1). We collected multilevel data—the longitudinal SHSE and 227 private investors’ daily stock happiness and portfolio changes for 36 consecutive trading days in four regions of China. Investors had an average liquid asset of $76,747.41 and $54,660.85 in stocks. This study is not a “one-shot” game with “nothing at stake.” We classified Shanghai and Beijing as the city and Shenzhen and Chongqing as the country. Our cross-level 3-D visualization reveals that regardless of SHSE volatility, investors with low aspiration, external control, and country domicile enjoy the highest and most sustainable stock happiness with minimum fluctuations. Independently, investors with low aspiration, external control, and country domicile tend to make fewer portfolio changes than their counterparts. Behaviorally, less is more, debunking the myth—risky decisions excite stock happiness. Our longitudinal study expands prospect theory, incorporates attitude toward money, and makes robust contributions to behavioral economics and business ethics. We help investors and ordinary citizens make happy, healthy, and wealthy decisions. Most importantly, the life you save may be your own. (shrink)

The antisaccade task provides a model paradigm that sets the inhibition of a reflexively driven behaviour against the volitional control of a goal-directed behaviour. The stability and adaptability of antisaccade performance was investigated in 23 neurologically healthy individuals. Behaviour and brain function were measured using functional magnetic resonance imaging (fMRI) prior to and immediately following two weeks of daily antisaccade training. Participants performed antisaccade trials faster with no change in directional error rate following two weeks of training; however this increased (...) speed came at the cost of the spatial accuracy of the saccade (gain) which became more hypometric following training. Training on the antisaccade task resulted in increases in fMRI activity in the fronto-basal ganglia-parietal-cerebellar ocular motor network. Following training, antisaccade latency was positively associated with fMRI activity in the frontal and supplementary eye fields, anterior cingulate and intraparietal sulcus; antisaccade gain was negatively associated with fMRI activity in supplementary eye fields, anterior cingulate, intraparietal sulcus and cerebellar vermis. In sum, the results suggest that following training, larger antisaccade latency is associated with larger activity in fronto-parietal-cerebellar ocular motor regions, and smaller antisaccade gain is associated with larger activity in fronto-parietal ocular motor regions.

BackgroundThis study explored the proportion of variance in depressive symptoms explained by processes targeted by BA (activation, behavioral avoidance, anticipatory pleasure, and brooding), and processes targeted by cognitive control training (cognitive control, attentional biases, and brooding).MethodsFive hundred and twenty adults were recruited. They completed a spatial cueing task as a measure of attentional biases and a cognitive task as a measure of cognitive control and completed self-report measures of activation, behavioral avoidance, anticipatory pleasure, brooding, and depressive symptoms. With path analysis (...) models, we explored the relationships between these predictors and depressive symptoms.ResultsBA processes were significant predictors of depressive symptoms, and activation partially predicted anticipatory pleasure, which in turn predicted depressive symptoms. However, cognitive control and attentional biases predicted neither brooding nor depressive symptoms. A comprehensive model including all processes fit the data but did not explain more of the variance in brooding or depressive symptoms than a model including only BA processes.LimitationsThe spatial cueing task was associated with low reliability and the use of a non-clinical sample limited the generalizability of the conclusions.ConclusionActivation, behavioral avoidance, brooding, and anticipatory pleasure are relevant processes to target in order to reduce depressive symptoms, while cognitive control and attentional biases are not.

We have analyzed many discrimination learning difficulties as reflecting multiple stimulus control topographies (SCTs). Nevin & Grace's analysis offers new variables to consider in the design of stimulus-control shaping procedures and cross-setting generalization of newly established behavior. A multiple-SCT perspective also suggests that fixed-trial discrimination procedures may offer advantages for reconciling momentum theory and partial reinforcement extinction effects.

This study analyzed the effects of aging on post-error behavioral adjustments from the perspective of cognitive control. A modified error awareness task was administered to young and older adults. In this task, two buttons were placed on the left and right sides in front of the participants, who were instructed to use the right button to perform a go/no-go task, and were notified if they made an error. There were three experimental conditions : participants had to push the right button (...) once in Condition A and twice in Condition B and C when a go-stimulus was presented. Conversely, participants were asked to withhold their response when a no-go stimulus was presented. Response inhibition differed depending on the experimental condition. The participants were asked to push the left button as quickly as possible when an error occurred. The results showed relatively longer reaction times to sudden errors among older adults compared with young adults. Furthermore, the difference in the error responses strongly influenced older adults’ response time after an error. These results suggest that the shift from proactive to reactive control may significantly influence post-error behavioral adjustments in older adults. (shrink)

Consistent with the planning–control model, recent fMRI data reveal that the inferior parietal lobe, the frontal lobes, and the basal ganglia are involved in motor planning. Inconsistent with the planning–control model, however, recent behavioral data reveal a spatial repulsion effect, indicating that the visual context surrounding the target can sometimes influence the on-line control of goal-directed action.

Many complex behaviors are genetically hardwired. Based on previous findings on genetic control of mating and other behaviors in invertebrate and mammalian systems, I suggest that genetic control of complex behaviors is modular: first, dedicated genes specify different behavioral patterns; secondly, separable genetic networks govern distinct behavioral components. I speculate that modular genetic encoding of complex behaviors may in part reflect modularity in brain development and function.Editor's suggested further reading in BioEssays From songs to synapses: Molecular (...) mechanisms of birdsong memory Abstract.

In this paper, I argue for two main hypotheses. First, that self-control is not a natural mental kind and, second, that there is no dedicated mechanism of self-control. By the first claim, I simply mean that those behaviors we label as “self-controlled” are a somewhat arbitrarily selected hodgepodge that do not have anything in common that distinguishes them from other behaviors. In other words, self-control is a gerrymandered property that does not correspond to a natural mental or psychological (...) kind. By the second claim, I mean that self-controlled behaviors are not produced by a mechanism that is not utilized in the production of other behaviors. Not only is there no natural mental property of self-control, there is no mechanism that is dedicated to producing self-controlled behavior. I further evaluate whether this account of self-control has enough explanatory power to account for a range of phenomena related to self-control. I argue that my account does a better job of explaining these phenomena than accounts which appeal to a dedicated self-control mechanism. (shrink)

Voluntary work behavior refers to spontaneous workplace behaviors that extend beyond role norms, including extra-role behaviors that benefit the organization and negative behaviors that may harm the organization. This study examined the relationship between self-control and VWB and the mediating role of job satisfaction. A total of 1,101 full-time employees from China completed a battery of self-report measures online. The results show that self-control positively predicts employees' OCB and negatively predicts employees' CWB. Moreover, job satisfaction significantly mediates (...) the relationship between self-control and OCB/CWB. The results confirm that employees with high self-control are more public-spirited, which previous studies have described as being “highly committed” or “less harmful”. This finding closely relates to the observation that employees with high self-control tend to have more satisfying work outcomes or higher workplace status than those with low self-control. (shrink)

Motor proficiency reflects the ability to perform precise and coordinated movements in different contexts. Previous research suggests that different profiles of motor proficiency may be associated with different cognitive functioning characteristics thus suggesting an interaction between cognitive and motor processes. The current study investigated this interaction in the general population of healthy adults with different profiles of motor proficiency by focusing on error-related cognitive control and behavioral adaptation mechanisms. In addition, the impact of these processes was assessed in terms of (...) trait anxiety and worries. Forty healthy adults were divided into high and low motor proficiency groups based on an assessment of their motor skills. Using electroencephalography during a flanker task, error-related negativity was measured as the neural indicator of cognitive control. Post-error slowing was measured to represent behavioral adaptation. Participants also completed an anxiety assessment questionnaire. Participants in the high motor proficiency group achieved better task accuracy and showed relatively enhanced cognitive control through increased ERN. Contrastingly, individuals in the lower motor proficiency group achieved poorer accuracy whilst showing some evidence of compensation through increased PES. Trait anxiety reflecting general worries was found to be correlated with motor functioning, but the study could not provide evidence that this was related to cognitive or behavioral control mechanisms. The interaction between cognitive and motor processes observed in this study is unique for healthy and sub-clinical populations and provides a baseline for the interpretation of similar investigations in individuals with motor disorders.

Pepper & Nettle argue that the more present-oriented behavior associated with a low socioeconomic status is an adaptive response to having relatively little control over the future. However, a study of fasters during Ramadan shows that self-imposed deprivation, which carries no implications regarding the ability to realize deferred rewards, is associated with loss and risk aversion.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.2 (2004) 125-128 [Access article in PDF] Comparing Psychoanalytic and Cognitive-Behavioral Perspectives on Control Bruce N. Waller Keywords freedom, locus of control, psychoanalysis, self-efficacy, volition Cognitive behavioral research on locus of control and self-efficacy has produced an extensive body of empirical results that might prove useful to psychoanalytic researchers endeavoring to strengthen the empirical foundation of psychoanalytic therapy. Cognitive-behaviorists and psychoanalysts share a common interest (...) in the importance of perspectives and belief systems and their impact on individual freedom, and comparative research on therapeutic effectiveness could yield benefits for both therapeutic approaches.Locus of control and self-efficacy are central elements in cognitive-behavioral psychology, and they play an important role in cognitive-behavioral therapy. Although the psychoanalytic approach does not explicitly employ those concepts, psychoanalytic therapists are obviously concerned with problems of effective action and internal obstacles to action. Attention to these two perspectives and their overlapping interests offers potential benefits for both the cognitive-behavioral and the psychodynamic approaches to psychological research and therapy.One potential benefit is the development of useful tools for advancing empirically based research on psychoanalysis. As Lehrer (1999) states, it is advantageous to ground psychoanalysis in "firm empirical evidence whenever possible." Although there have obviously been significant positive steps in that direction (Singer 2003; Weiss 1995, 1988; Weiss and Sampson 1986), psychoanalytic researchers have recognized that one source of difficulty is in finding clearly measurable research objectives and hypotheses (Burgin 2002). Cognitive-behavioral research on locus of control and self-efficacy has produced an extensive body of research using clear measurement standards that could prove useful in the empiricist approach to psychodynamic theories. In particular, those cognitive-behavioral research findings might offer a means of extending empirical investigation of psychodynamic theory in a direction usually regarded as difficult to test empirically: the study of psychoanalytic effectiveness to "change your way of seeing" (Lieberman 1999). Shifting locus of control or efficacy expectations in specific domains (Bandura 1997) [End Page 125] would empirically confirm the effectiveness of psychoanalytic techniques. It might well be that some efficacy expectations are enhanced more effectively by psychodynamic processes than by cognitive-behavioral therapy, or that psychoanalysis is effective in enhancing some specific efficacy expectations but not others. This could potentially extend the empirical examination of psychoanalytic theory as well as provide a base of comparison with cognitive-behavioral therapy techniques.Although self-efficacy enhancement might be a fruitful empirical test for psychodynamic therapy, therapeutic intervention to modify locus of control potentially could be even more productive. Current research indicates that one's orientation toward locus of control is a relatively stable characteristic, although it can be modified (Holyrod et al. 1984; Rotter 1979; Sadow and Hopkins 1993). One reason for locus of control stability may be that the locus of control imposes a perspective on the conceptualization of all one's experiences: from a strong internal locus of control perspective I view failures and successes as largely my own doing, whereas from an external locus perspective even my most effective efforts are seen as events that were outside my control: "I guess it was just my time to do well on a math exam," rather than "My hard work for that exam really paid off." (Lieberman makes this phenomenon quite clear in his excellent discussion of transparency.) Although locus of control is not easily modified, it is important to find effective means of helping subjects to achieve such changes, because research shows that a strong internal locus of control is positively correlated with success in work, sports, studies, marriage, and psychological adjustment (Lefcourt 1981, 1992), as well as with better health care behavior and better health (Bandura 1977; Schorr and Rodin 1982; Schulz 1976; Schulz and Hanusa 1978; Wallston 1993). Those deeply enmeshed in an external locus of control enjoy less real freedom and suffer severe disadvantages.How does one effect a shift in such a basic orientation? Not easily. From a psychoanalytic approach, the key will lie in recognizing and reconceptualizing the beliefs that impede effective action. Cognitive-behaviorists are more likely to... (shrink)

Schools have been the main context for physical activity and sedentary behavior interventions among adolescents, but there is inconsistent evidence on whether they also improve dimensions of the health−related quality of life. The aim of this study was to evaluate the effects of a school-based active lifestyle intervention on dimensions of HRQoL. A secondary aim was to verify whether sex, age, and HRQoL at baseline were moderators of the intervention effect. A cluster-randomized controlled trial was conducted at three control and (...) three intervention schools in Florianopolis, Brazil. All students from 7th to 9th grade were invited to participate. A school year intervention, designed primarily to increase PA and reduce SB, included strategies focused on teacher training on PA, SB, and nutrition, and availability of teaching materials related to these contents; environmental improvements ; and education strategies, with the availability of folders and posters regarding PA, SB, and nutrition. Participants and the research staffs were not blinded to group assignment, but a standardized evaluation protocol was applied at baseline and after the intervention using the KIDSCREEN−27 to assess HRQoL across five dimensions. Mixed linear models were performed to evaluate the effect of the Movimente intervention on the five HRQoL dimensions. Of the 921 students who answered the questionnaire at baseline, 300 and 434 completed the study in control and intervention groups, respectively. The results revealed no significant effects of the intervention on any HRQoL dimensions. A reduction of the school environment dimension was observed in both the control and intervention groups. Sensitivity analyses showed that students in the highest baseline tertiles of HRQoL in any dimension had a reduction in their respective scores from pre- to post-intervention in both school groups. In conclusion, our results demonstrated no intervention effect on HRQoL dimensions and those students with the highest levels of HRQoL at baseline on all dimensions reduced from pre to post-intervention.Clinical Trial RegistrationThe trial is registered at the Clinical Trial Registry.

Background:The understanding of factors that shape risk perception is crucial to modulate the perceived threat and, in turn, to promote optimal engagement in preventive actions.Methods:An on-line, cross-sectional, survey was conducted in Italy between May and July 2020 to investigate risk perception for COVID-19 and the adoption of preventive measures. A total of 964 volunteers participated in the study. Possible predictors of risk perception were identified through a hierarchical multiple linear regression analysis, including sociodemographic, epidemiological and, most of all, psychological factors. (...) A path analysis was adopted to probe the possible mediating role of risk perception on the relationship between the independent variables considered and the adoption of preventive measures.Results:Focusing on the psychological predictors of risk perception, high levels of anxiety, an anxious attachment, and an external locus of control predicted higher perceived risk. Conversely, high levels of openness personality and of avoidant attachment predicted a lower perception of risk. In turn, the higher was the perceived risk the higher was the adoption of precautionary measures. Furthermore, psychological factors influenced the adoption of preventive behaviors both directly and indirectly through their effect on risk perception.Conclusions:Our findings might be taken into high consideration by stakeholders, who are responsible for promoting a truthful perception of risk and proper compliance with precautionary measures.

ObjectiveCo-morbid insomnia and sleep apnea is a common and debilitating condition that is more difficult to treat compared to insomnia or sleep apnea-alone. Emerging evidence suggests that cognitive behavioral therapy for insomnia is effective in patients with COMISA, however, those with more severe sleep apnea and evidence of greater objective sleep disturbance may be less responsive to CBTi. Polysomnographic sleep study data has been used to predict treatment response to CBTi in patients with insomnia-alone, but not in patients with COMISA. (...) We used randomized controlled trial data to investigate polysomnographic predictors of insomnia improvement following CBTi, versus control in participants with COMISA.MethodsOne hundred and forty five participants with insomnia and sleep apnea [apnea-hypopnea index ≥ 15] were randomized to CBTi or no-treatment control. Mixed models were used to investigate the effect of pre-treatment AHI, sleep duration, and other traditional, and novel [quantitative electroencephalography ] polysomnographic predictors of between-group changes in Insomnia Severity Index scores from pre-treatment to post-treatment.ResultsCompared to control, CBTi was associated with greater ISI improvement among participants with; higher AHI, less wake after sleep onset, and less N3 sleep. No quantitative electroencephalographic, or other traditional polysomnographic variables predicted between-group ISI change.DiscussionAmong participants with COMISA, higher OSA severity predicted a greater treatment-response to CBTi, versus control. People with COMISA should be treated with CBTi, which is effective even in the presence of severe OSA and objective sleep disturbance. (shrink)

Self-control, so important in the theory and practice of psychology, has usually been understood introspectively. This target article adopts a behavioral view of the self (as an abstract class of behavioral actions) and of self-control (as an abstract behavioral pattern dominating a particular act) according to which the development of self-control is a molar/molecular conflict in the development of behavioral patterns. This subsumes the more typical view of self-control as a now/later conflict in which an act of self-control is a (...) choice of a larger but later reinforcer over a smaller but sooner reinforcer. If at some future time the smaller-sooner reinforcer will be more valuable than the larger-later reinforcer, self-control may be achieved through a commitment to the largerlater reinforcer prior to that point. According to some, there is a progressive internalization of commitment in the development of self-control. This presents theoretical and empirical problems. In two experiments temporal patterning of choices increased self-control. (shrink)

M. xanthus has a complex multicellular lifestyle including swarming, predation and development. These behaviors depend on the ability of the cells to achieve directed motility across solid surfaces. M. xanthus cells have evolved two motility systems including Type‐IV pili that act as grappling hooks and a controversial engine involving mucus secretion and fixed focal adhesion sites. The necessity for cells to coordinate the motility systems and to respond rapidly to environmental cues is reflected by a complex genetic network involving (...) at least three complete sets of chemosensory systems and eukaryotic‐like signaling proteins. In this review, we discuss recent advances suggesting that motor synchronization results from spatial oscillations of motility proteins. We further propose that these dynamics are modulated by the action of multiple upstream complementary signaling systems. M. xanthus is thus an exciting emerging model system to study the intricate processes of directed cell migration. BioEssays 30:733–743, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

The research reported in this article examined the influence of nurses’ attitudes, subjective norms and perceived behavioral control on maintaining patients’ privacy during hospitalization. The data were gathered from 109 nurses in six internal medicine wards at an Israeli hospital. The research was based on the theories of reasoned action and planned behavior. A positive and significant correlation was shown between nurses’ attitude to promoting and maintaining patient privacy and their planned behavior, while perceived behavioral control was the best variable (...) for predicting the nurses’ behavior. Better educated nurses believed that they had fewer resources and anticipated more obstacles in acting to promote and maintain patient privacy. This research adds a new dimension to what is already known about nurses’ attitudes to maintaining patients’ privacy, nurses’ planned behavior and their actual behavior. The practical implications of the findings are the identification of factors that influence the attitudes and behavior of nursing staff, which, in turn, will enable allocation of resources for solving difficulties and removing obstacles. The results will allow the formulation of educational programs to guide staff and also the application of policies based on both patient and nursing staff needs. (shrink)

Cognitive control of physical activity and sedentary behavior is receiving increased attention in the neuroscientific and behavioral medicine literature as a means of better understanding and improving the self-regulation of physical activity. Enhancing individuals’ cognitive control capacities may provide a resilient means to increase physical activity and reduce sedentary behavior. First, this paper reviews emerging evidence of the antecedence of cognitive control abilities in successful self-regulation of physical activity, and in precipitating self-regulation failure that predisposes to sedentary behavior. We then (...) highlight the brain networks that may underpin the cognitive control and self-regulation of physical activity, including the default mode network, prefrontal cortical networks and brain regions and pathways associated with reward. We then discuss research on cognitive training interventions that document improved cognitive control and that suggest promise of influencing physical activity regulation. Key cognitive training components likely to be the most effective at improving self-regulation are also highlighted. The review concludes with suggestions for future research. (shrink)

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains-losses domain and high-low probability. Pay dissatisfaction (in the losses domain) incites dishonesty in the name of justice at the individual level. The Corruption Perceptions Index, CPI, signals a high-low probability of getting caught for dishonesty at the country level. We theorize that decision-makers adopt avaricious love-of-money aspiration (...) as a lens and frame dishonesty in the gains-losses domain (pay satisfaction-dissatisfaction, Level 1) and high-low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction mitigates dishonesty across nations consistently. Based on 6500 managers in 32 countries, our cross-level three-dimensional visualization offers the following discoveries. Under high aspiration conditions, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations, supporting the certainty effect. However, pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities, sustaining the possibility effect—maximizing expected utility. Under low aspiration conditions, high pay satisfaction consistently leads to low dishonesty, demonstrating risk aversion—achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations. We enhance the S-shaped Curve to three 3-D corruption surfaces across three levels of the global economic pyramid, providing novel insights into behavioral economics, business ethics, the environment, and responsibility.

The goal of therapy is often to increase the momentum (persistence) of self-control behaviors. Determining how best to accomplish this goal necessitates conducting behavioral momentum research under a wider variety of conditions.

This paper provides an overview of developments in a dual processing theory of automatic and controlled processing that began with the empirical and theoretical work described by Schneider and Shiffrin (1977) and Shiffrin and Schneider (1977) over a quarter century ago. A review of relevant empirical findings suggests that there is a set of core behavioral phenomena reflecting differences between controlled and automatic processing that must be addressed by a successful theory. These phenomena relate to: consistency in training, serial versus (...) parallel processing, level of effort, robustness to stressors, degree of control, effects on long‐term memory, and priority encoding. We detail a computational model of controlled processing, CAP2, that accounts for these phenomena as emergent properties of an underlying hybrid computational architecture. The model employs a large network of distributed data modules that can categorize, buffer, associate, and prioritize information. Each module is a connectionist network with input and output layers, and each module communicates with a central Control System by outputting priority and activity report signals, and by receiving control signals. The Control System is composed of five processors including a Goal Processor, an Attention Controller, an Activity Monitor, an Episodic Store, and a Gating & Report Relay. The transition from controlled to automatic processing occurs in this model as the data modules become capable of transmitting their output without mediation by the Control System. We describe recent progress in mapping the components of this model onto specific neuroanatomical substrates, briefly discuss the potential for applying functional neuroimaging techniques to test the model's predictions, and its relation to other models.

Optimization models have often been useful in attempting to understand the adaptive significance of behavioral traits. Originally such models were applied to isolated aspects of behavior, such as foraging, mating, or parental behavior. In reality, organisms live in complex, ever-changing environments, and are simultaneously concerned with many behavioral choices and their consequences. This target article describes a dynamic modeling technique that can be used to analyze behavior in a unified way. The technique has been widely used in behavioral studies of (...) insects, fish, birds, mammals, and other organisms. The models use biologically meaningful parameters and variables, and lead to testable predictions. Limitations arise because nature's complexity always exceeds our modeling capacity. (shrink)

The contribution of this present paper is to propose a method that combines a chemical Brusselator reaction-diffusion system with a biological cell system via gap junction for controlling and visualizing the frequency and magnitude of chaotic intracellular calcium oscillations in two cell types, including nonexcitable cells and the glial cells. This produces a wide variety of oscillatory behaviors similar to those reported in numerous biological experiments. We particularly show that in the majority of chaos cases, the reactor to (...) cell coupling can induce the generation of regular calcium oscillations as the coupling strength is varied. Together with the proposed method of coupled models, the regularity of these chaotic oscillations enables us to gain better understanding and extensive insights into the overall coupling dynamics.

The Theory of Planned Behavior predicts that a combination of attitudes, perceived norms, and perceived behavioral control predict intentions, and that intentions ultimately predict behavior. Previous studies have found that the TPB can predict students’ engagement in plagiarism. Furthermore, the General Theory of Crime suggests that self-control is particularly important in predicting engagement in unethical behavior such as plagiarism. In Study 1, we incorporated self-control in a TPB model and tested whether norms, attitudes, and self-control predicted intention to plagiarize and (...) plagiarism behavior. The best statistical fit for the path-analytic model was achieved when a direct path from self-control to plagiarism engagement was specified. In Study 2, we added a measure of perceived behavioral control and split the measurement of norms into descriptive and injunctive components. This study found that both self-control and perceived-behavioral control additively contributed to the prediction of plagiarism and the path-analytic model achieved its best fit when direct paths from perceived norms to plagiarism behavior were specified. These studies suggest that setting strong anti-plagiarism norms, such as by the use of honor codes, and seeking to enhance students’ self-control may reduce engagement in plagiarism. (shrink)

This study characterizes a large sample of adults with attention-deficit/hyperactivity disorder and healthy controls regarding their task performance and neurophysiology; cross-sectionally and longitudinally. Self-reported symptoms, behavioral measures, and event-related potentials from a classical cued Go/NoGo task were used to outline the symptom burden, executive function deficits and neurophysiological features, and the associations between these domains. The study participants were assessed five or three times over two years. We describe cross-sectional and longitudinal group differences, and associations between symptom burden, and behavioral (...) and event-related potential components variables by latent growth curve models, including random slopes and intercepts. The ADHD group showed increased reaction time variability, increased commission and omission errors, and attenuated cueP3, CNV, N2d, and P3d amplitudes. We observed a decrease in self-reported symptoms in the ADHD group over the two years. The behavioral measures did not change over time, whereas the cueP3, P3d, and N2d amplitude attenuated in both groups. There was no evidence for a robust association between symptom burden and behavioral or ERP measures. The changes in the ERP components with stable task performance, potentially indicate more efficient neuronal processing over the two years. Whether the lack of association between symptom burden and behavioral or ERP measures might be due to the low reliability of the ADHD assessment criteria, or the inappropriateness of the objective measures cannot be inferred.

Current treatments for chronic pain have limited benefit. We describe a resilience intervention for individuals with chronic pain which is based on a model of viewing chronic pain as dysregulated homeostasis and which seeks to restore homeostatic self-regulation using strategies exemplified by survivors of extreme environments. The intervention is expected to have broad effects on well-being and positive emotional health, to improve cognitive functions, and to reduce pain symptoms thus helping to transform the suffering of pain into self-growth. A total (...) of 88 Veterans completed the pre-assessment and were randomly assigned to either the treatment intervention or control. Fifty-eight Veterans completed pre- and post-testing. The intervention covered resilience strengths organized into four modules: engagement, social relatedness, transformation of pain and building a good life. A broad set of standardized, well validated measures were used to assess three domains of functioning: health and well-being, symptoms, and cognitive functions. Two-way Analysis of Variance was used to detect group and time differences. Broadly, results indicated significant intervention and time effects across multiple domains: Pain decreased in present severity [F = 5.02, p < 0.05, η2p = 0.08], total pain over six domains [F = 14.52, p < 0.01, η2p = 0.21], and pain interference [F = 6.82, p < 0.05, η2p = 0.11]; Affect improved in pain-related negative affect [F = 7.44, p < 0.01, η2p = 0.12], fear [F = 7.70, p < 0.01, η2p = 0.12], and distress [F = 10.87, p < 0.01, η2p = 0.16]; Well-being increased in pain mobility [F = 5.45, p < 0.05, η2p = 0.09], vitality [F = 4.54, p < 0.05, η2p = 0.07], and emotional well-being [F = 5.53, p < 0.05, η2p = 0.09] Mental health symptoms and the cognitive functioning domain did not reveal significant effects. This resilience intervention based on homeostatic self-regulation and survival strategies of survivors of extreme external environments may provide additional sociopsychobiological tools for treating individuals with chronic pain that may extend beyond treating pain symptoms to improving emotional well-being and self-growth.Clinical Trial Registration: Registered with ClinicalTrials.gov.
