Being Clean and Acting Dirty: The Paradoxical Effect of Self-Cleansing

In two studies we investigated the association between physical cleansing and moral and immoral behavior in real-life situations. In Study 1, after a workout at the gym, participants cheated more after taking a shower than before taking one. In the second study, participants donated more money to charity before rather than after they bathed for religious purification. The results extend previous findings about moral cleansing and moral licensing and are discussed within the framework of conceptual metaphor theory.     

Remembering Friends as Not So Friendly in Competitive and Bargaining Social Interactions

From children's schoolyard play to executives' boardroom negotiations, competitive and bargaining interactions are common to everyday life. Sometimes, the interacting parties are socially close and sometimes not. In this research, we examine how friendship influences memory for actions in such interactions. Dyads consisting of either friends or strangers played a competitive card game (Study 1) or the ultimatum game (Studies 2 and 4) and then recalled the interaction. We find that participants remembered friends' play as more competitive (Study 1) and less generous (Studies 2 and 4) than strangers' play, even when friends' actual play was more generous than that of strangers (Studies 2 and 4). Friendship did not affect recall for one's own play. In a workplace setting, Study 3 reveals people expect more of work colleagues who are friends than of work colleagues who are acquaintances. Study 4 tests our complete model and shows that people expect more of friends than of strangers and that this difference in expectations explains the less favorable memory for friend's actions. Our findings are consistent with a negative disconfirmation account whereby people expect their friends to be less competitive and more generous, and when these expectations are violated, people remember friends' actions more negatively than they actually were. Much research shows positive effects of friendship norms on actual behavior. We demonstrate a negative effect on people's memory of friends' behavior in competitive and bargaining social interactions. Copyright © 2017 John Wiley & Sons, Ltd.     

Visual cues of motion that trigger animacy perception at birth: the case of self‐propulsion

Self‐propelled motion is a powerful cue that conveys information that an object is animate. In this case, animate refers to an entity's capacity to initiate motion without an applied external force. Sensitivity to this motion cue is present in infants that are a few months old, but whether this sensitivity is experience‐dependent or is already present at birth is unknown. Here, we tested newborns to examine whether predispositions to process self‐produced motion cues underlying animacy perception were present soon after birth. We systematically manipulated the onset of motion by self‐propulsion (Experiment 1) and the change in trajectory direction in the presence or absence of direct contact with an external object (Experiments 2 and 3) to investigate how these motion cues determine preference in newborns. Overall, data demonstrated that, at least at birth, the self‐propelled onset of motion is a crucial visual cue that allowed newborns to differentiate between self‐ and non‐self‐propelled objects (Experiment 1) because when this cue was removed, newborns did not manifest any visual preference (Experiment 2), even if they were able to discriminate between the stimuli (Experiment 3). To our knowledge, this is the first study aimed at identifying sensitivity in human newborns to the most basic and rudimentary motion cues that reliably trigger perceptions of animacy in adults. Our findings are compatible with the hypothesis of the existence of inborn predispositions to visual cues of motion that trigger animacy perception in adults.     

Spontaneous generalization of abstract multimodal patterns in young domestic chicks

From the early stages of life, learning the regularities associated with specific objects is crucial for making sense of experiences. Through filial imprinting, young precocial birds quickly learn the features of their social partners by mere exposure. It is not clear though to what extent chicks can extract abstract patterns of the visual and acoustic stimuli present in the imprinting object, and how they combine them. To investigate this issue, we exposed chicks (Gallus gallus) to three days of visual and acoustic imprinting, using either patterns with two identical items or patterns with two different items, presented visually, acoustically or in both modalities. Next, chicks were given a choice between the familiar and the unfamiliar pattern, present in either the multimodal, visual or acoustic modality. The responses to the novel stimuli were affected by their imprinting experience, and the effect was stronger for chicks imprinted with multimodal patterns than for the other groups. Interestingly, males and females adopted a different strategy, with males more attracted by unfamiliar patterns and females more attracted by familiar patterns. Our data show that chicks can generalize abstract patterns by mere exposure through filial imprinting and that multimodal stimulation is more effective than unimodal stimulation for pattern learning.     

Object individuation in 3-day-old chicks: use of property and spatiotemporal information

Object individuation was investigated in newborn domestic chicks. Chicks' spontaneous tendency to approach the larger group of familiar objects was exploited in a series of five experiments. In the first experiment newborn chicks were reared for 3 days with objects differing in either colour, shape or size. At test, each chick was presented with two groups of events: two objects differing in one property vs. two presentations of the same object. In both cases, all objects involved in the same group of events were sequentially presented and eventually concealed in a different spatial location, and the number of events taking place at each location was equalized. Chicks spontaneously approached the two different objects rather than the single object seen twice. Chicks did not just prefer the more varied set as they did not choose it when the two elements of each group of events were simultaneously presented (Experiment 2). Chicks succeeded when two different objects simultaneously presented were confronted with three identical ones simultaneously presented (Experiment 3), though they failed with sequential presentation of two different objects vs. one object presented three times if they had been familiarized with up to three identical objects (Experiment 4). Chicks instead succeeded if they had been familiarized with objects that were all different from one another (Experiment 5). These young birds thus proved able to use property and spatiotemporal information for object individuation.     

Modularity and spatial reorientation in a simple mind: encoding of geometric and nongeometric properties of a spatial environment by fish

When disoriented in environments with distinctive geometry, such as a closed rectangular arena, human infants and adult rats reorient in accord with the large-scale shape of the environment, but not in accord with nongeometric properties such as the colour of a wall. Human adults, however, conjoined geometric and nongeometric information to reorient themselves, which has led to the suggestion that spatial processing tends to become more flexible over development and evolution. We here show that fish tested in the same tasks perform like human adults and surpass rats and human infants. These findings suggest that the ability to make use of geometry for spatial reorientation is an ancient evolutionary tract and that flexibility and accessibility to multiple sources of information to reorient in space is more a matter of ecological adaptations than phylogenetic distance from humans.     

Ideal Epistemic Situations and the Accessibility of Realist Truth

There is a widespread opinion that the realist idea that whether a proposition is true or false typically depends on how things are independently of ourselves is bound to turn truth, in Davidson's words, into something to which humans can never legitimately aspire. This opinion accounts for the ongoing popularity of epistemic theories of truth, that is, of those theories that explain what it is for a proposition (or statement, or sentence, or what have you) to be true or false in terms of some epistemic notion, such as provability, justifiability, verifiability, rational acceptability, warranted assertibility, and so forth, in some suitably characterized epistemic situation. My aim in this paper is to show that the widespread opinion is erroneous and that the (legitimate) epistemological preoccupation with the accessibility of truth does not warrant the rejection of the realist intuition that truth is, at least for certain types of propositions, radically nonepistemic.     

The discursive “othering” of Jews and Muslims in the Britain First solidarity patrol

In this paper, critical discursive psychology is used to analyse the Islamophobic discourse by the far‐right party Britain First in its “solidarity patrol” video. Britain First patrolled in Golders Green, North London, to show support for Jewish communities following the ISIS shooting at the kosher supermarket in Paris on January 9, 2015. The Charlie Hebdo shooting and the shooting at the kosher supermarket (as well as other attacks by members of the Islamic State) have led to Muslims being seen as a threat to Britain and exposed to Islamophobic attacks and racial abuse. This presents far‐right parties in the United Kingdom with the dilemma of appearing moderate and mainstream in their anti‐Islamic stance. The analysis focuses on how Britain First used the shooting at the kosher supermarket in order to construct Jews as under threat from Islam. The analysis also includes visual communication in the solidarity patrol video that was used to provide “evidence” that Britain First supported Jewish communities. Results are discussed in light of how Britain First used aligning with Jews in order to appear as “reasonable” in projecting its anti‐Islamic ideology and how critical discursive psychology can be used to show how conflicting social identities are constructed.     

Preference for symmetry is experience dependent in newborn chicks (Gallus gallus)

Spontaneous pecking preferences toward symmetric or asymmetric stimuli were tested in newborn chicks (Gallus gallus). A preference for asymmetric patterns was found in na?ve chicks (either 24 or 48 hours old), although a preference for symmetry appeared at retest after chicks had experienced standard rearing conditions (Experiments 1 and 2). Only food-experienced chicks preferred symmetric patterns; food-deprived and hand-fed chicks did not show any preference (Experiment 3). A key factor that allowed for the emergence of a preference for symmetry may relate to the improving of pecking sensorimotor skills occurring during active food manipulation. Possible explanations are discussed for the late emergence of the preference for symmetry and for the preference for asymmetry found in na?ve chicks.
