Numerous social, economic and academic pressures can have a negative impact on representations of biomedical research. We review several of the forces playing an increasingly pernicious role in how health and science information is interpreted, shared and used, drawing discussions towards the role of narrative. In turn, we explore how aspects of narrative are used in different social contexts and communication environments, and present creative responses that may help counter the negative trends. As traditional methods of communication have in many (...) ways failed the public, changes in approach are required, including the creative use of narratives. (shrink)

What are the neural correlates of conscious visual awareness? Tackling this question requires contrasting neural correlates of stimulus processing culminating in visual awareness with neural correlates of stimulus processing unaccompanied by awareness. To contrast these two neural states, one must be able to erase an otherwise visible stimulus from awareness. This paper describes and critiques visual phenomena involving dissociation of physical stimulation and conscious awareness: degraded stimulation, visual masking, visual crowding, bistable figures, binocular rivalry, motion-induced blindness, inattentional blindness, change blindness (...) and attentional blink. While no single strategy stands above the others, those producing changing visual awareness despite invariant physical stimulation are clearly preferable. (shrink)

Among psychologists and vision scientists,binocular rivalry has enjoyed sustainedinterest for decades dating back to the 19thcentury. In recent years, however, rivalry''saudience has expanded to includeneuroscientists who envision rivalry as a tool for exploring the neural concomitants ofconscious visual awareness and perceptualorganization. For rivalry''s potential to berealized, workers using this tool need toknow details of this fascinating phenomenon,and providing those details is the purpose ofthis article. After placing rivalry in ahistorical context, I summarize major findingsconcerning the spatial characteristics and thetemporal dynamics (...) of rivalry, discuss two majortheoretical accounts of rivalry ( eye vs stimulus rivalry) and speculate on possibleneural concomitants of binocular rivalry.

BackgroundPrivate umbilical cord blood banking is a for-profit industry in which parents pay to store blood for potential future use. Governments have noted the tendency for private banks to oversell the potential for cord blood use, especially in relation to speculative cell therapies not yet supported by clinical evidence. We assessed the regulatory landscape governing private cord bank marketing in Canada.Main bodyBecause the problematic marketing of private cord blood banking for future use often relates to speculative future cell therapies that (...) do not exist and are not being advertised for current clinical use, most private blood bank marketing seems to fall outside Health Canada’s regulatory scope. However, this problematic marketing is regulated by the Competition Bureau pursuant to the Competition Act. While representations relating to future hypothetical treatments may not always be subject to the legal requirement for claim substantiation, the law also prohibits individuals and companies from knowingly or recklessly making representations that are “false or misleading in a material respect.” A representation is materially false or misleading when it could “influence a consumer’s behavior or purchasing decisions,” and consumers are likely to be considered to be “credulous and inexperienced” for the purposes of assessing an advertisement’s general impression. Because all of the potential benefit of the banking is derived from the potential future use of the biological material for health interventions directed toward the customers and their relatives, and because we know the best available medical evidence indicates a very low probability of utility in this context, we can say with confidence that some private cord blood banking claims are materially misleading. Moreover, to the extent that medical professionals are involved in private bank interactions with customers or hold ownership stakes in private banks, they are subject to professional codes, standards of practice, and potentially fiduciary obligations that further prohibit misleading marketing.ConclusionsPrivate cord blood bank marketing that advertises hypothetical future treatments can be misleading and may influence consumer behaviour. This marketing may breach existing advertising law. Regulatory bodies should enforce the law in order to help prevent public health and personal financial harm. (shrink)

Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response “the heebie jeebies”. In Study 1, coding of 76 participants’ experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants’ (...) responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli. Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct.

The federal government is funding a sea change in health care by investing in interventions targeting social determinants of health, which are significant contributors to illness and health inequity. This funding power has encouraged states, professional and accreditation organizations, health care entities, and providers to focus heavily on social determinants. We examine how this shift in focus affects clinical practice in the fields of oncology and emergency medicine, and highlight potential areas of reform.

Colour synaesthesia is the mental experience involving a strong association between specific colours and specific auditory stimuli, such as words, or achromatic visual stimuli, such as numerals or letters. In the contemporary literature on colour synaesthesia, the majority view treats the phenomenon as one arising from some of the same neural events mediating colour perception triggered by genuinely coloured objects; this view that synaesthesia is perceptually based, however, is not universally endorsed. What strategies have been utilized to evaluate the perceptual (...) reality of colour synaesthesia, and what is the evidence produced by those strategies? This chapter tackles those questions within the context of colour graphemic synaesthesia, the most widely studied form of synaesthesia. We divide the research strategies into those employing behavioral measures to assess whether synaesthetia influences performance on tasks known to be sensitive stimulus colour and those employing indirect measures that use physiological responses as proxies for colour perception. Our chapter concludes that there is sufficient justification for the belief in the perceptual reality of colour grapheme synaesthesia. At the same time, we applaud those who remain disbelievers, for their skepticism has underscored the logical issues surrounding research on this question. (shrink)

Firearm injury in the United States is a public health crisis in which physicians are uniquely situated to intervene. However, their ability to mitigate harm is limited by a complex array of laws and regulations that shape their role in firearm injury prevention. This piece uses four clinical scenarios to illustrate how these laws and regulations impact physician practice, including patient counseling, injury reporting, and the use of court orders and involuntary holds. Unintended consequences on clinical practice of laws intended (...) to reduce firearm injury are also discussed. Lessons drawn from these cases suggest that physicians require more nuanced education on this topic, and that policymakers should consult front-line healthcare providers when designing firearm policies.

People with grapheme-color synesthesia perceive specific colors when viewing different letters or numbers. Previous studies have suggested that synesthetic color experience can be bistable when induced by an ambiguous character. However, the exact relationship between processes underlying the identity of an alphanumeric character and the experience of the induced synesthetic color has not been examined. In the present study, we explored this by focusing on the temporal relation of inducer identification and color emergence using inducers whose identity could be rendered (...) ambiguous upon rotation of the characters. Specifically, achromatic alphabetic letters and digits were presented at varying angles to 9 grapheme-color synesthetes. Results showed that grapheme identification and synesthetically perceived grapheme color covary with the orientation of the test stimulus and that synesthetes were slower naming the experienced color than identifying the character, particularly at intermediate angles where ambiguity was greatest.

Many Luther scholars have made passing reference to Martin Luther’s theology of the Word as a ‘speech-act’ theology. This essay aims to probe points of continuity and discontinuity between Luther’s understanding of the Word, as exemplified in the promise of God, and a particular speech-act philosophy as posited by John Searle. The analysis of Searle in the area of declarations, as well as a survey of Lutheran conceptions of the Word of promise in both sacrament and Scripture, will evidence specific (...) moments of clarity in Luther’s so-called ‘speech-act’ theology and provide a helpful paradigm for viewing the creative impact of the Word as conceived by Luther.

Magda Arnold is recognised as one of the pioneers of modern cognitive approaches to the study of emotion. Indeed, her definition of appraisal is still employed more or less unchanged by many researchers. Somewhat less well known is Arnold's broader theory of emotion, personality, and human development that formed the context for her ideas about appraisal. In this paper, I examine the influence of the psychology of Thomas Aquinas on Arnold's thinking about appraisal, emotion, the self and self-actualisation. I then (...) critique current conceptions of appraisal in the light of her ideas about emotion and the person. I end with a plea to broaden our conception of what constitutes a moral emotion.

Sociopolitical attitudes are often the root cause of conflicts between individuals, groups, and even nations, but little is known about the origin of individual differences in sociopolitical orientation. We test a combination of economic and evolutionary ideas about the degree to which the mating market, sex, age, and income affect sociopolitical orientation. We collected data online through Amazon’s Mechanical Turk from 1108 US participants who were between 18 and 60, fluent in English, and single. While ostensibly testing a new online (...) dating website, participants created an online dating profile and described people they would like to date. We manipulated the participants’ popularity in the mating market and the size of the market and then measured participants’ sociopolitical attitudes. The sociopolitical attitudes were reduced to five dimensions via Principal Components Analysis. Both manipulations affected attitudes toward wealth redistribution but were largely not significant predictors of the other dimensions. Men reported more unrestricted sociosexual attitudes, and more support for benevolent sexism and traditional family values, than women did, and women supported wealth redistribution more than men did. There was no sex difference in accepting nonconforming behaviors. Younger people and people with lower incomes were more liberal than older people and people with higher incomes, respectively, regardless of sex. Overall, effects were largely not interactive, suggesting that individual differences in sociopolitical orientation may reflect strategic self-interest and be more straightforward than previously predicted.

Over 5 million college students in the United States – nearly one-in-three students currently enrolled – are of immigrant origin, meaning they are either the children of immigrant parents or guardians and/or immigrants themselves. These students accounted for almost 60% of the growth in higher education enrolment in the 21st century. Nevertheless, there is very little research dedicated to this student population's specific experiences of postsecondary education, with similar absences discernible within the realms of higher education policy and practice. Although (...) college campuses are making important progress in building more inclusive spaces, conversations about climate and student care rarely account for the journeys of students of immigrant origin. Featuring 20 chapters written by more than 50 contributors, this book addresses this glaring omission. The authors examine how students of immigrant origin experience the road to, through, and beyond higher education, while, simultaneously, speaking to evidence-based implications for policy, research, and practice.

Macphail’s “null hypothesis,” that there are no differences in intelligence, qualitative, or quantitative, between non-human vertebrates has been controversial. This controversy can be useful if it encourages interest in acquiring a detailed understanding of how non-human animals express flexible problem-solving capacity (“intelligence”), but limiting the discussion to vertebrates is too arbitrary. As an example, we focus here on Portia, a spider with an especially intricate predatory strategy and a preference for other spiders as prey. We review research on pre-planned detours, (...) expectancy violation, and a capacity to solve confinement problems where, in each of these three contexts, there is experimental evidence of innate cognitive capacities and reliance on internal representation. These cognitive capacities are related to, but not identical to, intelligence. When discussing intelligence, as when discussing cognition, it is more useful to envisage a continuum instead of something that is simply present or not; in other words, a continuum pertaining to flexible problem-solving capacity for “intelligence” and a continuum pertaining to reliance on internal representation for “cognition.” When envisaging a continuum pertaining to intelligence, Daniel Dennett’s notion of four Creatures (Darwinian, Skinnerian, Popperian, and Gregorian) is of interest, with the distinction between Skinnerian and Popperian Creatures being especially relevant when considering Portia. When we consider these distinctions, a case can be made for Portia being a Popperian Creature. Like Skinnerian Creatures, Popperian Creatures express flexible problem solving capacity, but the manner in which this capacity is expressed by Popperian Creatures is more distinctively cognitive.

Depression is a widespread concern in the United States. Neuromodulation treatments are becoming more common but there is emerging concern for racial disparities in neuromodulation treatment utilization. This study focuses on Transcranial Magnetic Stimulation (TMS), a treatment for depression, and the structural and attitudinal barriers that racialized individuals face in accessing it. In January 2023 participants from the Twin Cities, Minnesota engaged in focus groups, coupled with an educational video intervention. Individuals self identified as non-white who had no previous TMS (...) exposure but had tried at least one treatment for their depression. Results revealed that the intervention did not notably change knowledge or stigma about TMS, but attitudes surrounding traveling for treatment changed. Notably, barriers like affordability, frequency of treatment, and lack of knowledge persist. Participants expressed a desire for more information, personal connection, and a tailored educational approach. The study suggests a need for multifaceted strategies to reduce disparities, focusing on education, community-based resources, and policy interventions. Immediate actions that can be taken include the creation of a TMS education program focused on patient engagement and awareness about TMS. (shrink)

The developmental evidence for children's respect for ownership reveals that children will enforce the property rights of third parties before they themselves respect other's property. This pattern of development suggests the need for clarification or modification of the minimalist model. Here, I consider three explanations for the gap between knowledge and behavior for respect of ownership.

The interocular suppression technique termed continuous flash suppression (CFS) has become an immensely popular tool for investigating visual processing outside of awareness. The emerging picture from studies using CFS is that extensive processing of a visual stimulus, including its semantic and affective content, occurs despite suppression from awareness of that stimulus by CFS. However, the current implementation of CFS in many studies examining processing outside of awareness has several drawbacks that may be improved upon for future studies using CFS. In (...) this paper, we address some of those shortcomings, particularly ones that affect the assessment of unawareness during CFS, and ones to do with the use of ‘visible’ conditions that are often included as a comparison to a CFS condition. We also discuss potential biases in stimulus processing as a result of spatial attention and feature-selective suppression. We suggest practical guidelines that minimize the effects of those limitations in using CFS to study visual processing outside of awareness. (shrink)

Maya in Physics in a synthesis of modern physics and the Advaita Vedanta with an integral thesis emerging out of the confluence. In the exposition of the Advaita Vedanta its philosophy has been reinterpreted in the light of modern science. In this process the vedanta has been demystified and physics dematerialized Instead of being confined to inter school parallelism only this book tries ot present a total vision of the entire cosmos and its dependence on Brahman the transcendental being which (...) is the non dual reality Maya the power of Brahman or the Primordial Unmanifest Nature has been assigned a metaphysical status without violating the traditionality of the Vedanta. Part I of the book deals with classical Newtonian physics, thermodynamics, relativity, quantum physics, particle physics, astrophysics, and cosmology. Part II is a presentation of the Advaita Vedanta, in a modern format. Part III is a confluence of the Advaita Vedanta and modern science (especially physics). An integral thesis emerges out of the confluence. There has been an amalgam of spirituality and science. The whole approach is holistic, synthetic, and integral. (shrink)
