Effects of warned and unwarned demand transitions on vigilance performance and stress

The present study was designed to explore the effects of warned and unwarned demand transitions in vigilance on performance and self-reported stress. Twenty observers (10 women and 10 men) were assigned at random to each of six conditions resulting from the factorial combination of signal salience (high and low salience signals) and switching (no switch, switch with warning, and switch without warning). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. While demand transitions did destabilize subsequent performance, increasing intra-individual variability, overall performance efficiency was uninfluenced by either switching or warning. Demand transitions, whether warned or not, increased self-reported distress. A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model.     

The price of deceptive behavior: Disliking and lying to people who lie to us

We hypothesized that frequency and quality of deception influences how people perceive those who lie to them and that people subsequently increase deceptive behavior as a consequence of being lied to. In Study 1, participants were covertly videotaped conversing with a partner. Following the conversation, participants evaluated partners, and partners reviewed the videotape, identifying deceptions that they told. Findings indicated that partner’s frequency of deception was inversely related to likeability. In Study 2, participants watched a videotape of a confederate who appeared to produce one or four exaggerated or minimized lies, and then evaluated the confederate. Participants and confederates subsequently engaged in a conversation. When participants witnessed either one exaggerated lie, one or four minimal lies, or no lies they trusted and liked the confederate more than when witnessing four exaggerated lies. Moreover, participants increased their own use of deception as a function of the severity and quantity of confederate’s lies.     

Self-mutilation and coping strategies in a college sample

The goal of this study was to examine the use of specific coping strategies among self-mutilating college students. The self-mutilating group (n = 44) reported utilizing avoidance strategies more often than did a control group (n = 44) matched for general psychological distress but with no history of self-mutilation. In addition, female, but not male, self-mutilators endorsed using problem-solving and social support seeking strategies less often than nonmutilators. These findings suggest that coping strategies in general and avoidance-based strategies in particular may be important targets for the treatment of self-mutilative behaviors.     

Rats (Rattus norvegicus) encode the shape of an array of discrete objects

To navigate efficiently, a traveler must establish a heading using a frame of reference. A large body of evidence has indicated that humans and a variety of nonhuman animals utilize the geometry, or shape, of enclosed spaces as a frame of reference to determine their heading. An important and yet unresolved question is whether shape information from arrays of discrete objects and enclosed environments are represented, and utilized, in the same way. In the present study, rats were presented with a reference memory task in which they had to find water that was hidden in 1 of 4 discrete and unique objects placed at the vertices of a rectangle. The results indicate that rats could utilize both feature and geometry cues to locate the hidden goal. The rats' performance declined during transformation tests using a triangular array, indicating that the rats may have encoded the primary axis of the object array, rather than local cues, to direct their search.     

Tomorrow I’ll be me: The effect of time perspective on the activation of idealistic versus pragmatic selves

It is widely accepted that the self-system is dynamic and consists of multiple selves that emerge under different contexts. The present research describes two types of diverging self-conceptions, the idealistic and pragmatic selves. Building on a synthesis of construal level theory with research on the self, we propose that a more distal time perspective activates an idealistic versus a pragmatic self. Self-activation, in turn, influences the preference between two major motives: maximizing identity versus instrumental benefits. A series of five studies supported this conceptualization by demonstrating that: (a) distal rather than proximal time perspective enhances the preference for identity over instrumental benefits; (b) people construe themselves as relatively more idealistic than pragmatic when primed with a distal than proximal time perspective, and (c) self-activation mediates the effect of time perspective on preference. The studies also investigate boundary conditions and process measures that shed light on the interface between time, self, and preference. The final section discusses the theoretical implications for the literatures on construal level, self, and justice and the practical implications for organizational behavior, political psychology, and human decision-making.     

Moral outrage mediates the dampening effect of system justification on support for redistributive social policies

To understand how and why people tolerate ongoing social and economic inequality, we conducted two studies investigating the hypothesis that system justification is associated with reduced emotional distress and a lack of support for helping the disadvantaged. In Study 1, we found that the endorsement of a system-justifying ideology was negatively associated with moral outrage, existential guilt, and support for helping the disadvantaged. In Study 2, the induction of a system-justification mind-set through exposure to "rags-to-riches" narratives decreased moral outrage, negative affect, and therefore intentions to help the disadvantaged. In both studies, moral outrage (outward-focused distress) was found to mediate the dampening effect of system justification on support for redistribution, whereas existential guilt (Study 1) or negative affect in general (Study 2; inward-focused distress) did not. Thus, system-justifying ideology appears to undercut the redistribution of social and economic resources by alleviating moral outrage.     

The Other Side of Injustice: When Unfair Procedures Increase Group-Serving Behavior

ABSTRACT— Greater group identification and higher levels of procedural justice typically work together to encourage group members to engage in group-serving cooperative behavior. However, when people who already identify with a group receive information indicating that the group is procedurally unjust, their motivation to engage in group-serving behavior may increase. This article reports two studies in which college students' identification with their university was measured and information about the procedural justice of the university was manipulated. Study 1 used an explicit measure of group identification and a deliberative measure of group-serving behavior. Study 2 used an implicit measure of group identification and both deliberative and spontaneous measures of group-serving behavior. The findings of both studies support the hypothesis that among people who are highly identified with a group, learning about the group's injustice leads to short-term increases in group-serving behavior.     

Two pathways to stimulus encoding in category learning?

Category learning theorists tacitly assume that stimuli are encoded by a single pathway. Motivated by theories of object recognition, we evaluated a dual-pathway account of stimulus encoding. The part-based pathway establishes mappings between sensory input and symbols that encode discrete stimulus features, whereas the image-based pathway applies holistic templates to sensory input. Our experiments used rule-plus-exception structures, in which one exception item in each category violates a salient regularity and must be distinguished from other items. In Experiment 1, we found discrete representations to be crucial for recognition of exceptions following brief training. Experiments 2 and 3 involved multisession training regimens designed to encourage either part- or image-based encoding. We found that both pathways are able to support exception encoding, but have unique characteristics. We speculate that one advantage of the part-based pathway is the ability to generalize across domains, whereas the image-based pathway provides faster and more effortless recognition.     

The danger of Durkheim: Ambiguity in the theory of social effervescence

The purpose of this article is to shed light on an ambiguity in Émile Durkheim's theory of social effervescence. Durkheim's failure to distinguish two kinds of effervescence at the heart of the religious rite has left a dangerous legacy in the study of religion. If his work is read, however, in light of René Girard's theory of the violent origins of religion, his analysis of la société can retain the distinction between the effervescence of the crowd in scapegoating and the effervescence of protecting the victims of scapegoating. This thesis is tested by briefly comparing some contemporary essays on Durkheim.
