Generalisation in evaluative conditioning occurs when the valence acquired by a conditional stimulus (CS), after repeated pairing with an unconditional stimulus (US), spreads to stimuli that are similar to the CS (generalisation stimuli, GS). CS evaluations can be updated via CS instructions that conflict with prior conditioning (negative conditioning + positive instruction). We examined whether CS instructions can update GS evaluations after conditioning. We used alien stimuli where one alien (CSp) from a fictional group was paired with (...) pleasant US images and another alien (CSu) from a different group was paired with unpleasant US images. The other members from the two groups were used as GSs. After conditioning, participants received negative CSp instructions and positive CSu instructions. In Experiment 1, explicit and implicit GS evaluations were measured before and after the instructions. In Experiment 2, we used a between-participants design where one group received positive/negative CS instructions while a control group received neutral instructions. In both experiments, the positive/negative CS instructions caused a reversal of explicit GS evaluations and an elimination of implicit GS evaluations. The findings suggest that generalised evaluations can change after CS instructions which may have implications for interventions aimed at reducing negative group attitudes. (shrink)

Negative conditional stimulus valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person was paired with an aversive US, while another was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information (...) about the CS− poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS−. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding. (shrink)

Analyses of dispositional ascriptions in terms of conditional statements famously confront the problems of finks and masks. We argue that conditional analyses of dispositions, even those tailored to avoid finks and masks, face five further problems. These are the problems of: (i) Achilles' heels, (ii) accidental closeness, (iii) comparatives, (iv) explaining context sensitivity, and (v) absent stimulus conditions. We conclude by offering a proposal that avoids all seven of these problems.

During evaluative conditioning, a neutral conditional stimulus becomes pleasant or unpleasant after pairings with a positive/negative unconditional stimulus. Measures of US expectancy are...

In fear differential conditioning, stimuli that resemble the conditioned stimulus (CS+) are more likely to trigger fear responses. Excessive fear responses on stimuli not like CS + are often associated with anxiety. However, the threat judgments process and how this process manifests itself differently in subgroups with different generalisation rule applications, is unclear. This study examines whether anxiety biases the threat decision process in fear generalisation paradigm and whether subgroups characterised by different generalisation gradients was interpreted differently by drift-diffusion (...) model. We gathered behavioural data through a binary fear generalisation judgment task and clustered participants based on their responses. Reaction time distributions and individual scale scores were analyzed using the hierarchical drift-diffusion model. The model results suggested that similarity and state anxiety facilitated evidence-gathering processes that favoured “threat” judgments, but at the same time, state anxiety weakened the effect of stimulus similarity as evidence. Further cluster analyses revealed that this effect of anxiety on threat judgments only held true for specific subgroups of participants. This pioneering computational modelling effort in fear generalisation underscores the significant role of strategy preference and its complex interaction with anxiety in shaping stimulus processing.

Pursuing Jacques Derrida's reflections on the possibility of "religion without religion," John Llewelyn makes room for a sense of the religious that does not depend on the religions or traditional notions of God or gods. Beginning with Derrida's statement that it was Kierkegaard to whom he remained most faithful, Llewelyn reads Kant, Hegel, Nietzsche, Feuerbach, Heidegger, Sartre, Levinas, Deleuze, Marion, as well as Kierkegaard and Derrida, in original and compelling ways. Llewelyn puts religiousness in vital touch with the struggles of (...) the human condition, finding religious space in the margins between the secular and the religions, transcendence and immanence, faith and knowledge, affirmation and despair, lucidity and madness. This provocative and philosophically rich account shows why and where the religious matters. (shrink)

Evaluative conditioning refers to the changes in liking of an evaluatively neutral stimulus (the conditional stimulus or CS) as a result of merely pairing it with another, already liked or disliked stimulus (the unconditional stimulus or US). We examined whether other, non‐evaluative stimulus properties of a US can also be associatively transferred to a CS. In a series of experiments, we tried to transfer perceptions of the gender of children and the gender of first (...) names. We found evidence for the associative transfer of these properties but only when participants were aware of the contingencies. (shrink)

The principle of differential marginality (Casajus in Theory and Decis 71(2):163-–174) for cooperative games is a very appealing property that requires equal productivity differentials to translate into equal payoff differentials. In this paper we apply this property to axiomatic characterizations of values. We show that differential marginality implies additivity and symmetry under certain conditions. Based on this result, we propose new characterizations of the equal division and the equal surplus division values. Finally, we characterize two classes of convex combinations of (...) values, i.e., α\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\alpha$$\end{document}-egalitarian Shapley values and α\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\alpha$$\end{document}-equal surplus division values, by employing differential marginality and establishing the uniqueness of these values on inessential games.

Evaluative conditioning (EC) refers to the change in the valence of a conditioned stimulus (CS) due to its pairing with a positive or negative unconditioned stimulus (US). To the extent that core affect can be characterised by the two dimensions of valence and arousal, EC has important implications for the origin of affective responses. However, the distinction between valence and arousal is rarely considered in research on EC or conditioned responses more generally. Measuring the subjective feelings elicited by (...) a CS, the results from two experiments showed that (1) repeated pairings of a CS with a positive or negative US of either high or low arousal led to corresponding changes in both CS valence and CS arousal, (2) changes in CS arousal, but not changes in CS valence, were significantly related to recollective memory for CS–US pairings, (3) subsequent presentations of the CS without the US reduced the conditioned valence of the CS, with conditioned arousal being less susceptible to extinction and (4) EC effects were stronger for high arousal than low arousal USs. The results indicate that the conditioning of affective responses can occur simultaneously along two independent dimensions, supporting evidence in related areas that calls for a consideration of both valence and arousal. Implications for research on EC and the acquisition of emotional dispositions are discussed. (shrink)

Which and how much of our current drives –individually and as a global community– are driven by ancestral, inherited traits or imprinted on our animal condition? An attempt to approximate this intriguing query is explored here. It pertains to our identity, social constructions, and our ecological interaction. The origin of our species has its roots in ancestral habits, behaviors and a survival drive, transformed from changing environmental conditions. We were not born in a mother-of-pearl cradle nor were protected by magical (...) agents. We grew on the thread of time within the complex nature of bio-ecological interactions. They carved our identity, our genetic expression and the possible origin of our beliefs, resulting in an arch of various behaviors and cultural phenotypes. The biological nature of our construction dragged through millennia through species trials with variable rates of survival times provided traces of inconstant and multiple evolutive chains. Our modern cultural contexts –norms, priorities, values– appear as newly born. Yet, socio-cultural ecology upon which our brain organization and behavioral constructs derive include shared basic behavioral drives with non-human primates. The emergence of humans with a sophisticated language allowed the development of complex virtual constructs based on symbolism and the instruments of culture. This has enhanced cognitive capacity and emotional interaction supported by processes anchored in neural networks distributed within cortical and subcortical levels. Basic, essential neural connectivities were preserved during the evolutionary development of the species. The biological matrix and inheritance are usually segregated from the social and cultural construction. Sophistication of our cultural development tends to set up a divisive fault from primitive foundations of non-human animal behavior (survival, territory, reproduction, prevalence, access to nutrients). These are basic templates and underlie essential individual and group basic drives, and cultural constructs. Humans have not ceased from being territorial (whether applied to virtual or material dimensions). Various forms of social inequities have been expressed in our time and through human history. On evolutive terms, the notion of individual social status within the social structure of a gregarious community generated the probability of an individual ascending or descending that hierarchy. Thus, becoming a potential figure of leadership, or the subordinate or the marginalized. Is there an evolutive antecedent for human social inequities? How do we construct a different future? Post-industrial societies became increasingly dependent on material consumerism and technological cultures, to the point of embraining them; conceptually becoming technological hybrids. Are these a developmental must, or an uncontrolled spin-off of human inventiveness affecting our future? Construction of supernatural agents played a significant role in the socialization/domestication processes. Agents’ intentionality flourished through altered states of conscience, or under fear of natural phenomena attributed to supposed inhabitants of the Natural Kingdom or virtual beings. This imaginary universe, reinforced by ritual behaviors, contributed to control personal/collective distress of various possible origins and conditioned our degrees of emotional and cognitive freedom.
