The shielding function of task sets and its relaxation during task switching

The goal of the presented experiments was to investigate the dynamic interplay of task shielding and its relaxation during task switching. Task shielding refers to the finding that single task sets in terms of 2-choice categorization rules help shielding against distraction from irrelevant stimulus attributes. During task switching, this shielding should temporarily be relaxed to prevent the perseveration of the previous task, on the downside making the system more vulnerable toward the intrusion of irrelevant information. Participants had to switch between a digit and a letter categorization task. An irrelevant stimulus feature (Experiment 1: color, Experiment 2: font) varied randomly, orthogonal to the task. The presence or absence of an interaction of the irrelevant feature (switch vs. repetition) and the response (switch vs. repetition) was taken as evidence for the absence or presence of task shielding, respectively. Replicating previous results, irrelevant feature and response did not interact on task repetitions, indicating successful shielding. On task switches, however, the irrelevant feature interacted with the response, supporting the assumption that task shielding is temporarily relaxed during task switching.     

Cyberbullying Victimization in Adolescents as Related to Body Esteem,Social Support,and Social Self-Efficacy

ABSTRACT

The authors examined cyberbullying victimization in the context of issues of key importance to youth: body esteem, social support, and social self-efficacy. Research has found that traditional peer-bullying victimization is significantly correlated with low body esteem in Western societies, especially pertaining to weight (R. Puhl & J. Luedicke, 2012 Puhl, R., & Luedicke, J. (2012). Weight-based victimization among adolescents in the school setting: Emotional reactions and coping behaviors. Journal of Youth & Adolescence, 41, 27–40. [Google Scholar]). Studies have also found a relationship among bullying victimization, appearance-related bullying, low body esteem, and psychosocial difficulties among youth (L. E. Park, R. M. Calogero, A.F. Young, & A. Diraddo, 2010 Park, L. E., Calogero, R. M., Young, A. F., & Diraddo, A. (2010). Appearance-Based Rejection Sensitivity predicts Body Dysmorphic Disorder symptoms and cosmetic surgery acceptance. Journal Of Social & Clinical Psychology, 29, 489–509. [Google Scholar]). However, the emergence of cyberbullying, characterized by its own special features (P. K. Smith et al., 2008 Smith, P. K., Mahdavi, J., Carvalho, M., Fisher, S., Russell, S., & Tippett, N. (2008). Cyberbullying: Its nature and impact in secondary school pupils. Journal of Child Psychology and Psychiatry, 49, 376–385. [Google Scholar]), has raised a salient need to explore the relationship between cyber victimization and body esteem, no less important with social framework, because both are key components in adolescents' lives that may be associated with cyberbullying victimization. The authors examined these relationships among 204 Israeli adolescents 14–16 years old. The results indicate a noteworthy prevalence (45%) of cyber victims. Cyber victimization is significantly correlated with low body esteem and low social support and social self-efficacy. Low body esteem and low social support predicted the probability of being a cyber victim. The results extend the knowledge about potential personal and social risk factors for cyber victimization during adolescence. Implications for specific intervention programs are discussed.     

Emotion regulation choice in an evaluative context: the moderating role of self-esteem

Evaluative contexts can be stressful, but relatively little is known about how different individuals who vary in responses to self-evaluation make emotion regulatory choices to cope in these situations. To address this gap, participants who vary in self-esteem gave an impromptu speech, rated how they perceived they had performed on multiple evaluative dimensions, and subsequently chose between disengaging attention from emotional processing (distraction) and engaging with emotional processing via changing its meaning (reappraisal), while waiting to receive feedback regarding these evaluative dimensions. According to our framework, distraction can offer stronger short-term relief than reappraisal, but, distraction is costly in the long run relative to reappraisal because it does not allow learning from evaluative feedback. We predicted and found that participants with lower (but not higher) self-esteem react defensively to threat of failure by seeking short-term relief via distraction over the long-term benefit of reappraisal, as perceived failure increases. Implications for the understanding of emotion regulation and self-esteem are discussed.     

Identity affirmation and social movement support

It is argued that the power of collective identification to mobilize people for collective action such as social movement support derives at least partly from processes of identity affirmation. The hypothesized identity‐affirming function of social movement support is tested in two laboratory experiments which revolve around collective identity as a supporter of the peace movement. In Experiment 1, we predicted and found that people who strongly identified with the peace movement showed more movement support (i.e. made more monetary donations to the peace movement) under conditions of uncertain as opposed to certain possession of identity as a movement supporter. In Experiment 2, we replicated this finding, but also found, in accordance with the notion of substitution, that the mobilizing effect of uncertain collective‐identity possession was undermined when an identity symbol was available that could function as a surrogate for more costly identity‐affirming behaviour. Further conceptual and social implications of the identity‐affirming function of social movement support are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Cross-talk of instructed and applied arbitrary visuomotor mappings

Humans are able to perform any voluntary motor response to any environmental stimulus. This cornerstone of the flexibility of human behaviour has been investigated under the label of arbitrary visuomotor mapping. The focus of research has been the question as to how these mappings are executed once the subjects have been instructed appropriately. However, one question has been rather neglected thus far: what, in the first place, enables humans to instantaneously implement any arbitrary S-R mapping by mere instruction! We report an experiment assessing the cross-talk of arbitrary S-R mappings as a part of the instructed task representation, on the one hand, and the cross-talk of repetitively applied mappings, on the other hand. The results show a behavioural dissociation of the cross-talk elicited by instructed and applied mappings, suggesting that the first occurs on the level of task-set, whereas the latter occurs on the level of specific S-R associations.     

Anti-realism and speaker knowledge

Dummettian anti-realism repudiates the realist's notion of verification-transcendent truth. Perhaps the most crucial element in the Dummettian attack on realist truth is the critique of so-called realist semantics, which assigns verification-transcendent truth-conditions as the meanings of (some) sentences. The Dummettian critique charges that realist semantics cannot serve as an adequate theory of meaning for a natural language, and that, consequently, the realist conception of truth must be rejected as well. In arguing for this, Dummett and his followers have appealed to a certain conception of linguistic knowledge. This paper examines closely the appeal to speakers' knowledge of linguistic meaning, its force and limitations.     

Goal Orientations and Tendency to Neutralize Academic Cheating: An Ecological Perspective

This study examined the phenomenon of academic cheating while focusing on the unique and interactive effects of sociocultural variables on academic motivation, goal orientation and self-efficacy perception of 221 Muslim and Jewish female students. A mixed quantitative and qualitative research design with Multivariate-Analysis of Covariance, Step-wise Discriminant Function Analysis, Path Analysis and semi-structured interviews have been used to clarify the data obtained in various scales. Path Analysis indicated that the main factor predicting the tendency to neutralize academic cheating was the performance goal of pleasing parents mediated by extrinsic motivation. Further analysis showed between-ethnic-groups differences with Muslim students being more extrinsically motivated by the performance goal of pleasing the parents. Content analysis of the interviews conducted with 22 students showed that, in contrast to the Jewish students?? individualistic perspective, Muslim students' collective perspective put them under tremendous pressure to succeed due to the rippling effect of success on all spheres of life e.g., family??s honor, community standing, and future marriage prospects.     

The contribution of negative reproductive experiences and chronic medical conditions to depression and pain among Israeli women

This study of 302 Israeli women sought to investigate the associations among stressful reproductive experiences (e.g. fertility problems, abortions, and traumatic births), chronic medical conditions, pain, and depression. The specific aims of the study were to examine (1) the effect of stressful reproductive experiences, chronic medical conditions, and pain on depressive symptoms and (2) the effect of stressful reproductive experiences, chronic medical conditions, and depressive symptoms on pain. Our findings corroborate with previous studies demonstrating that depression and pain are two interrelated, but different phenomena, which have both common and distinct risk factors. The findings are discussed in the light of stress and adaptation theories that point to the long-term effects of stressful life events on emotional and physiological aspects such as depression and pain.     

Assessing the Connection between Students’ Justice Experience and Attitudes Toward Academic Cheating in Higher Education New Learning Environments

The present study is aimed at comprehensively assess tendency to neutralize (justify) academic cheating as a function of individual experience of teachers’ just behavior and new learning environments (NLE), while considering the Belief in a Just World (BJW) as a personal resource that has the potential to enhance those experiences. Data were collected from a sample of 193 second-year undergraduate college students. Path analysis main results showed that students who evaluated their teachers’ behavior toward them personally as just, held more positive evaluation of the learning environment, and were less inclined toward academic cheating neutralization. Personal BJW was partly associated with the perceived NLE, this connection was primarily mediated by the experience of teacher justice. Moreover, students’ evaluation of their teachers’ just behavior was a stronger negative predictor of academic cheating neutralization than perceived forms of NLE. Interpretation of these results, applications and implications for future research are discussed.
