The effect of expectancy of a threatening event on time perception in human adults

Two experiments were conducted to investigate the effect of a threatening stimulus in human adults in a temporal bisection task. In Experiment 1, for two anchor duration conditions (400/800 vs. 800/1600 ms), the participants completed trials in which the probe duration was followed by an aversive stimulus or a nonaversive stimulus. The results showed that the duration was judged longer when the participants expected an aversive rather than a nonaversive stimulus. In Experiment 2, the effect of the temporal localization of the aversive stimulus was also tested, with the aversive stimulus being presented at the beginning or at the end of the probe duration. The results revealed a temporal overestimation in each condition compared to the trials in which no aversive stimulus was presented. Furthermore, the temporal overestimation was greater when the expectation for the forthcoming threatening stimulus was longer. This temporal overestimation is explained in terms of a speeding-up of the neural timing system in response to the increase in the arousal level produced by the expectation of a threatening stimulus.     

A Cognitive Model of Dynamic Cooperation With Varied Interdependency Information

We analyze the dynamics of repeated interaction of two players in the Prisoner's Dilemma (PD) under various levels of interdependency information and propose an instance‐based learning cognitive model (IBL‐PD) to explain how cooperation emerges over time. Six hypotheses are tested regarding how a player accounts for an opponent's outcomes: the selfish hypothesis suggests ignoring information about the opponent and utilizing only the player's own outcomes; the extreme fairness hypothesis weighs the player's own and the opponent's outcomes equally; the moderate fairness hypothesis weighs the opponent's outcomes less than the player's own outcomes to various extents; the linear increasing hypothesis increasingly weighs the opponent's outcomes at a constant rate with repeated interactions; the hyperbolic discounting hypothesis increasingly and nonlinearly weighs the opponent's outcomes over time; and the dynamic expectations hypothesis dynamically adjusts the weight a player gives to the opponent's outcomes, according to the gap between the expected and the actual outcomes in each interaction. When players lack explicit feedback about their opponent's choices and outcomes, results are consistent with the selfish hypothesis; however, when this information is made explicit, the best predictions result from the dynamic expectations hypothesis.     

How the Consideration of Positive Emotions Influences Persuasion: The Differential Effect of Pride Versus Joy

Although pride and joy are both positive emotions, we expected their consideration to affect persuasion differently because of the different perspectives (near vs. distant) and level of abstractness they involve, with pride being more abstract than joy. Therefore, we predicted that when the attitude object is construed at a high level rather than a low level, the consideration of pride is likely to promote more persuasion than the consideration of joy. In three studies, we found that the consideration of pride, when featured in the persuasion message (Studies 1a and 1b) or incidentally (Study 2), increased persuasion more than did the consideration of joy, when the persuasion object was temporally distant compared with temporally near (Studies 1a and 1b) or construed as a high‐level category compared with a more concrete individual (Study 2). These findings advance our understanding of the ways in which specific emotions may affect persuasion, beyond valence. Copyright © 2014 John Wiley & Sons, Ltd.     

The intergenerational transmission of ethnic essentialism: how parents talk counts the most

The present study analyzed the role of parents as potential sources of children's essentialist beliefs about ethnicity. We tested 76 parent–child (5‐year‐olds) dyads of Jewish Israeli parents from three social groups, defined by the kindergartens children attended: national religious, secular, or Jewish‐Arab integrated. We assessed parents' and children's beliefs, and parents' usage of ethnic attitudinal and categorization markers in a book‐reading activity. Overall, national religious parents manifested the strongest ethnic essentialism and endorsement of anti‐negotiations with Palestinians, and were the most likely to express negative attitudes and mark ethnic categories in their conversations with their children. Moreover, regression analyses revealed that ethnic categorization in parents' speech was the most reliable predictor of children's ethnic essentialism. Ethnic essentialism is transmitted to children not via explicit communication of intergroup beliefs or attitudes, but rather via the sheer marking of categories in ways that resonate with children's own intuitive ways of conceptualizing the social world.     

Predicting the use of corporal punishment: Child aggression,parent religiosity,and the BDNF gene

Corporal punishment (CP) has been associated with deleterious child outcomes, highlighting the importance of understanding its underpinnings. Although several factors have been linked with parents’ CP use, genetic influences on CP have rarely been studied, and an integrative view examining the interplay between different predictors of CP is missing. We focused on the separate and joint effects of religiosity, child aggression, parent's gender, and a valine (Val) to methionine (Met) substitution in the brain‐derived neurotrophic factor (BDNF) gene. Data came from a twin sample (51% male, aged 6.5 years). We used mothers’ and fathers’ self‐reports of CP and religiosity, and the other parent's report on child aggression. Complete data were available for 244 mothers and their 466 children, and for 217 fathers and their 409 children. The random split method was employed to examine replicability. For mothers, only the effect of religiosity appeared to replicate. For fathers, several effects predicting CP use replicated in both samples: child aggression, child sex, religiosity, and a three‐way (GxExE) interaction implicating fathers’ BDNF genotype, child aggression and religiosity. Religious fathers who carried the Met allele and had an aggressive child used CP more frequently; in contrast, secular fathers’ CP use was not affected by their BDNF genotype or child aggression. Results were also repeated longitudinally in a subsample with age 8–9 data. Findings highlight the utility of a bio‐ecological approach for studying CP use by shedding light on pertinent gene‐environment interaction processes. Possible implications for intervention and public policy are discussed.

Family Interdependence,Spiritual Perspective,Self-Transcendence,and Depression Among Korean College Students

The purpose of this study was to examine the mechanisms that might account for the effects of spirituality and self-transcendence on Korean college students’ depression among 197 Korean fathers, mothers, and children. A structural equation analysis indicated that spiritual perspective related to lower depression through the mediating pathway of self-transcendence for individuals. Mothers’ spiritual perspective and self-transcendence related to their children’s depression through the mediating pathway of their own depression, but the same was not true for fathers. Findings help explicate the intergenerational transmission of depression and important predictors of depression related to spirituality.     

The undesired: on nudniks in Jewish American fiction

This essay discusses the recurring preoccupation in Jewish literature with the character of the nudnik, a popular figure in Jewish culture but a rather neglected one in scholarly studies. Even though the nudnik appears in many stories throughout the years, from Sholem Aleichem’s, through Franz Kafka’s, to Isaac Bashevis Singer’s stories and novels – nowhere was he more prominent than in post–World War II Jewish American fiction, more specifically in the short stories and novels of Philip Roth and Bernard Malamud. Both Roth and Malamud depict the nudnik as an embodiment of a generational divide, between the tormented Americanized young and the tormenting “Ostjuden” old. And yet, while Malamud’s nudniks serve as a critique on the fate of Jewish culture and tradition in post-Holocaust America, Roth identifies the character of the nudnik as a contaminating element that will forever haunt the younger individual. By discussing the Yiddish term “nudnik” and its ambivalent and unsettling nature in these writers’ texts, this essay will highlight the cultural impact on modern Jewish identity of the nudnik within each story.     

Redefining membership in animal groups

Groups of animals—flocks, herds, shoals, and swarms—are often dynamical entities. Relative positions of group members change, and most groups divide and re-form on multiple timescales. Few studies, however, have attempted to define when an animal is or is not within a group. Most authors adopt arbitrary distance thresholds, such as the elective group size (EGS), which assume that animals closer than some threshold distance are in the same group. In the present article, we define a group-membership criterion derived from dynamical statistical considerations and based on detailed trajectories of all members of a moving group. We demonstrate the use of our criterion to track the comings and goings in shoals of zebrafish (Danio rerio) and the gradual dissolution of the shoal across multiple exposures to a testing tank. We present a novel measure of group cohesion based on our group membership criterion and demonstrate that excursions away from the shoal explain some previous observations of the dynamics of shoaling. Finally, we show that excursions away from a shoal are accompanied by an increase in swimming speed. Applying similar criteria to data from other species may clarify some of the common features of animal collective motion.     

The value of value: Further excursions on the meaning and role of customer value

Grounded on fundamental marketing principles, the concept of customer value has been revisited and refined by academicians and practitioners for the last 30 years. However, research devoted to achieving a consistent theoretical and conceptual development of value‐related concepts has proceeded apace without ever reaching full closure. The present essay seeks reasons behind remaining deficiencies in value‐related research and offers a review intended to move our understanding of customer value toward what promises to become a more enlightened future. The topic of value is approached by theoretical analysis and conceptual development. First, “the challenge” of value research is presented: the researcher faces a topic that is central to the marketing discipline but that suffers from various conceptual and methodological difficulties. Second, among the literature on value from the last three decades, two main research areas are selected: the conceptual delimitation and the methodological links between quality, satisfaction, and value. Third, as a conclusion, we identify several streams of research that promise to expand future knowledge in the area of customer value. Several tables and figures that provide a systematic and structured review of value‐related knowledge support this inventory of the state‐of‐the‐art in value research. Even the most patient theoretical development of value‐related concepts tends to resist full conceptual closure. The breadth of customer value and its richness for marketing implications encourage novel and refreshing approaches. Copyright © 2011 John Wiley & Sons, Ltd.
