Encoding strategies in self-initiated visual working memory

During a typical day, visual working memory (VWM) is recruited to temporarily maintain visual information. Although individuals often memorize external visual information provided to them, on many other occasions they memorize information they have constructed themselves. The latter aspect of memory, which we term self-initiated WM, is prevalent in everyday behavior but has largely been overlooked in the research literature. In the present study we employed a modified change detection task in which participants constructed the displays they memorized, by selecting three or four abstract shapes or real-world objects and placing them at three or four locations in a circular display of eight locations. Half of the trials included identical targets that participants could select. The results demonstrated consistent strategies across participants. To enhance memory performance, participants reported selecting abstract shapes they could verbalize, but they preferred real-world objects with distinct visual features. Furthermore, participants constructed structured memory displays, most frequently based on the Gestalt organization cue of symmetry, and to a lesser extent on cues of proximity and similarity. When identical items were selected, participants mostly placed them in close proximity, demonstrating the construction of configurations based on the interaction between several Gestalt cues. The present results are consistent with recent findings in VWM, showing that memory for visual displays based on Gestalt organization cues can benefit VWM, suggesting that individuals have access to metacognitive knowledge on the benefit of structure in VWM. More generally, this study demonstrates how individuals interact with the world by actively structuring their surroundings to enhance performance.

Behavioral training and predisposed coping strategies interact to influence resilience in male Long-Evans rats: implications for depression

Effective coping strategies and adaptive behavioral training build resilience against stress-induced pathology. Both predisposed and acquired coping strategies were investigated in rats to determine their impact on stress responsiveness and emotional resilience. Male Long-Evans rats were assigned to one of the three coping groups: passive, active, or variable copers. Rats were then randomly assigned to either an effort-based reward (EBR) contingent training group or a non-contingent training group. Following EBR training, rats were tested in appetitive and stressful challenge tasks. Physiological responses included changes in fecal corticosterone and dehydroepiandrosterone (DHEA) metabolites as well as neuropeptide Y (NPY)-immunoreactivity in the hippocampus and amygdala. Regardless of a rat's predisposed coping strategy, EBR rats persisted longer than non-contingent rats in the appetitive problem-solving task. Furthermore, training and coping styles interacted to yield the seemingly most adaptive DHEA/corticosterone ratios in the EBR-trained variable copers. Regardless of training group, variable copers exhibited increased NPY-immunoreactivity in the CA1 region.     

The role of developmental features,environmental crises,and personal resources (self-control and social support) in adolescents' aggressive behavior

Aggression among adolescents is a social problem that has sharply escalated in recent years, instigating research into related factors. This article outlines the characteristics of adolescents' aggressive behavior in line with Buss and Perry's (1992) theory linking it to the tendency to develop hostile thoughts and angry emotions. Aggressive behavior may be described as a possible outcome of normal development on the one hand, and as a result of exposure to crisis and trauma on the other. Thus, developmental characteristics highlight the role of age and sex in adolescents' aggressive behavior. In addition, possible external crises and distress (e.g., war, divorce) may contribute to adolescents' aggression. This article also identifies two possible resources that may contribute to a reduction in aggressive behavior under normal and crisis conditions: social support as an environmental resource, and self-control as a personal resource. We conclude with suggestions for reducing aggression through a unified intervention setting that integrates developmental features, environmental and family components, as well as personal components.     

Organizational citizenship behaviour and employee's strain: Examining the buffering effects of leader support and participation in decision making

Investing in citizenship behaviours could entail personal costs for the employee. Specifically, we argue that OCB contributes to employee's strain above and beyond the impact of role conflict, role ambiguity, and role overload. To study the buffering role of leader support and participation in decision making (PDM) on this relationship, we collected data from 457 employees at various organizations at different time points from multisources. The results supported our hypotheses: Higher levels of OCB were related to higher levels of employee's strain, above and beyond the impact of role overload, role ambiguity, and role conflict; and the relationship between OCB and strain was weaker for those enjoying a high degree of leader support or PDM.     

Middle School Transition from the Strengths Perspective: Young Adolescents’ Character Strengths, Subjective Well-Being, and School Adjustment

The study examined the longitudinal associations of adolescents’ character strengths with subjective well-being and school adjustment during the pivotal period of the transition to middle school. The study followed 417 students and 13 teachers from four public middle schools in the center of Israel during seventh and eighth grade. Students completed questionnaires about their character strengths, life satisfaction, and positive and negative affects. Students’ school adjustment was measured through grade point average and questionnaires given to the students’ teachers. Findings provided extensive support for the associations among character strengths, subjective well-being (SWB), and middle school adjustment. Intellectual and temperance strengths were central in the prediction of students’ school performance and achievements. Interpersonal strengths were significantly related to social functioning at school. Temperance and transcendence strengths were robust positive predictors of students’ SWB. The findings extend existing knowledge about character and its relation to optimal functioning and well-being among young adolescents, and have important practical implications for applying strengths-building practices at middle schools.     

Phonological and Orthographic Processing of Hebrew Words: Electrophysiological Aspects

Brain activity among 15 male, college-level, normal readers in Israel was examined during phonological and orthographic word-recognition tasks. Both electrophysiological (event-related potentials, or ERPs) and behavioral measures were obtained. Data indicated that (a) behavioral accuracy was almost perfect for all the experimental tasks, and (b) although P200 and N400 ERP components were elicited in the experimental tasks, the latencies of those components were significantly longer and their amplitudes significantly higher in the phonological task. Variations in vowel information had no effect on word recognition in either type of task. The results suggest that among skilled readers of Hebrew, phonological processing during word recognition may be more effortful and may demand greater cognitive resources than orthographic processing. Furthermore, the additional phonological information represented in vowels appears to contribute little to word recognition in this population. These findings support earlier research on skilled reading in Hebrew as well as current theoretical models of reading.     

Mediation and Moderated Mediation in the Relationship Among Role Models,Self‐Efficacy,Entrepreneurial Career Intention,and Gender

This paper addresses the effects of role models and self‐efficacy on forming career intentions, and whether the effects vary by gender and process. Focusing on entrepreneurship as a career choice, we explored (a) the effect of exposure to entrepreneurial role models on entrepreneurial career intention; (b) the difference in effects between men and women; and (c) the mediating functionality of self‐efficacy. Results indicate that role models have a significant and positive impact on intention, that gender moderated the effects, and that self‐efficacy mediated it. A moderated mediation relationship was observed such that, for women, role models had stronger influence on self‐efficacy, which, in turn, influenced entrepreneurial career intention. Results are discussed in terms of implications for theory and practice.     

‘For our garden of remembrance is somewhere else’: Narratives of separation through the eyes of Freud's patients

This article presents a unique collection of narratives of separation – unique because the separation here is from psychoanalysis and from Freud as analyst. These narratives were published as part of memoirs written about Freud by three of his patients. Their narratives of separation give us an innovative point of view on the psychoanalytic process, in particular with respect to the importance they place on the termination phase of the analysis at a time when Freud himself had not given it much consideration. The three autobiographical texts are Abram Kardiner's memoir (1977); the memoir of Sergei Pankejeff, known as the Wolf Man (Gardiner, 1971a ); and ‘Tribute to Freud’, by the poet H.D. ( 1974 ). These three distinguished narratives are discussed here as works of translation, as understood by Walter Benjamin (1968 [1955]), Paul Ricoeur (2006 [2004]), and Jean Laplanche (1999 [1992]). They express translation under three aspects: reconstruction of the past (the work of memory), interpreting the conscious residues of the transference (the work of mourning), and, as a deferred action, deciphering the enigmatic messages received from Freud as the parental figure. This representation of the analysand's writing suggests that the separation from analysis is an endless work of translation within the endless process of deciphering the unconscious.     

Self-initiated object-location memory in young and older adults

The present study explored self-initiated object-location memory in ecological contexts, as aspect of memory that is largely absent from the research literature. Young and older adults memorized objects-location associations they selected themselves or object-location associations provided to them, and elaborated on the strategy they used when selecting the locations themselves. Retrieval took place 30 min and 1 month after encoding. The results showed an age-related decline in self-initiated and provided object-location memory. Older adults benefited from self-initiation more than young adults when tested after 30 min, while the benefit was equal when tested after 1 month. Furthermore, elaboration enhanced memory only in older adults, and only after 30 min. Both age groups used deep encoding strategies on the majority of the trials, but their percentage was lower in older adults. Overall, the study demonstrated the processes involved in self-initiated object-location memory, which is an essential part of everyday functioning.
