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.     

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.

     

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.     

Olfactory perception as a compass for olfactory neural maps

The mammalian brain commonly uses structural proximity to reflect proximity in stimulus and perceptual space. Objects or object features that are near each other in physical structure or perception are also near each other in the brain. This generates sensory maps. The topography of olfactory connectivity implies a rudimentary map in the olfactory epithelium, a more intricate map in the olfactory bulb, but no ordered topography is evident in piriform cortex. Currently, we are largely unable to link the ordered topography in epithelium and bulb to meaningful olfactory axes within a strong predictive framework. We argue that the path to uncovering such a predictive framework depends on systematically characterizing olfactory perception, and we describe initial efforts in this direction.     

Convincing Yourself to Care About Others: An Intervention for Enhancing Benevolence Values

To study value change, this research presents an intervention with multiple exercises designed to instigate change through both effortful and automatic routes. Aiming to increase the importance attributed to benevolence values, which reflect the motivation to help and care for others, the intervention combines three mechanisms for value change (self‐persuasion, consistency‐maintenance, and priming). In three experiments, 142 undergraduates (67% male, ages 19–26) participated in an intervention emphasizing the importance of either helping others (benevolence condition) or recognizing flexibility in personality (control condition). We measured the importance of benevolence values before and after the task. In Experiment 1, the intervention increased U.S. participants' benevolence values. In Experiment 2, we replicated these effects in a different culture (Israel) and also showed that by enhancing benevolence values, the intervention increased participants' willingness to volunteer to help others. Experiment 3 showed that the increases in the importance of benevolence values lasted at least 4 weeks. Our results provide evidence that value change does not require fictitious feedback or information about social norms, but can occur through a 30‐min intervention that evokes both effortful and automatic processes.     

Integrating Content and Structure Aspects of the Self: Traits,Values, and Self‐Improvement

Research on the structure of the self has mostly developed separately from research on its content. Taking an integrative approach, we studied two structural aspects of the self associated with self‐improvement—self‐discrepancies and perceived mutability—by focusing on two content areas, traits and values. In Studies 1A–C, 337 students (61% female) reported self‐discrepancies in values and traits, with the finding that self‐discrepancies in values are smaller than in traits. In Study 2 (80 students, 41% female), we experimentally induced either high or low mutability and measured perceived mutability of traits and values. We found that values are perceived as less mutable than traits. In Study 3, 99 high school students (60% female) reported their values, traits, and the extent to which they wish to change them. We found that values predict the wish to change traits, whereas traits do not predict the wish to change values. In Study 4, 172 students (47.7% female) were assigned to one of four experimental conditions in which they received feedback denoting either uniqueness or similarity to others, on either their values or their traits. The results indicated that feedback that one's values (but not traits) are unique affected self‐esteem. Integrating between theories of content and structure of the self can contribute to the development of both.     

Overriding “Doing Wrong” and “Not Doing Right”: Validation of the Dispositional Self-Control Scale (DSC)

We present the Dispositional Self-Control (DSC) Scale, which reflects individuals’ tendency to override 2 types of temptations, termed doing wrong and not doing right. We report a series of 5 studies designed to test the reliability and validity of the scale. As hypothesized, high DSC predicts distant future orientation and low DSC predicts deviant behaviors such as aggression, alcohol misuse, and aberrant driving. DSC also predicts task performance among resource-depleted participants. Taken together, these findings suggest that the DSC Scale could be a useful tool toward further understanding the role of personality in overcoming self-control challenges.     

The interaction between alerting and executive control: Dissociating phasic arousal and temporal expectancy

In recent years, studies have revealed an interaction between two systems of attention—alerting and executive control. Specifically, warning cues increase the influence of cognitive conflict under certain conditions. One of the problems of interpreting this effect is that warning cues can trigger two processes simultaneously—a high arousal state and strategic temporal expectancy. The goal of the present study was to clarify which process underlies the increased congruency effects following a warning event. In two experiments, the influence of warning cues on flanker congruency was examined while controlling for the effects of temporal expectancy and arousal. Experiment 1 revealed a strong effect of warning cues on congruency, even when the warning cues were not temporally predictive. This effect was evident at two short cue-to-target intervals of 100 and 500 ms, but not following a 900-ms interval. Experiment 2 revealed that this effect was not altered even when the warning cues predicted with high certainty that the target would appear at long cue-to-target intervals (e.g., 900 ms). We suggest that the interaction between alerting and executive control reflects the involvement of a subcortical mechanism responsible for increasing arousal.     

What aspects of face processing are impaired in developmental prosopagnosia?

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensive battery of well-established tasks. The tasks included measures of sensitivity to global motion and to global form, detection that a stimulus is a face, determination of its sex, holistic face processing, processing of face identity based on features, contour, and the spacing of features, and judgments of attractiveness. The DP cases showed normal sensitivity to global motion and global form and performed normally on our tests of face detection and holistic processing. On the other tasks, many DP cases were impaired but there was no systematic pattern. At least half showed deficits in processing of facial identity based on either the outer contour or spacing of the internal features, and/or on judgments of attractiveness. Three of the eight were impaired in processing facial identify based on the shape of internal features. The results show that DP is a heterogeneous condition and that impairment in recognizing faces cannot be predicted by poor performance on any one measure of face processing.
