Evaluation of a conflict-resolution and problem-solving programme to enhance adolescents' self-concept

The effectiveness of an intervention programme, initially designed to enhance the self-concept and motivation of gifted underachieving girls, was evaluated for students identified as having a low self-concept and social relationship difficulties. Twenty male and female secondary-school students were randomly assigned to either a treatment or a control group. The programme, called ABLE (Attribution, Behaviour, Life skills Education), incorporates problem-solving, conflict resolution, and a multidimensional framework to investigate adolescents' self-concept formation. The adolescents in the study made significant improvements in the areas of general self-concept, physical appearance self-concept, and total self-concept. Teaching conflict-resolution and problem-solving skills had a beneficial influence on self-concept. The results are discussed in terms of the relevance of the programme and its application to school and counselling interventions.     

Communicating Negative Hire Decisions to Applicants: Fulfilling Psychological Contracts

This study demonstrates that characteristics of rejection letters combine in a complex manner to affect impressions of the organization, and likelihood of re-applying to and of patronizing the organization. Specifically, the most negative reactions to rejection letters were found when a contact person existed, along with a long time interval before receiving a letter that failed to include an explicit statement of rejection. Some support was found for the failure to receive a rejection letter as a psychological contract violation.     

Aggression and conventional rule violation among adolescents: Social-reasoning predictors of social behavior

The goal of the current study was to determine whether aggressive and conventional rule-violating behaviors could be predicted by social-cognitive beliefs and values regarding aggression and conventional rule violations. The extent to which adolescents (N = 398; grades 9 through 12) engaged in both aggressive behavior and conventional school rule violations was assessed using self-ratings and peer nominations. Results indicated that aggressive and conventional rule-violating behaviors were predicted by (1) beliefs about the legitimacy of aggressive and convention-violating behavior; (2) values placed on the expected outcomes of these acts, such as negative self-evaluations, peer disapproval, and tangible rewards; and (3) beliefs about the effects of these acts on others. Furthermore, the results indicated that aggressive and conventional transgressions were predicted better by beliefs and values within the same social-cognitive domain than across domains. In contrast to females, male students committed more aggressive acts and conventional rule violations and reported beliefs and values that were more supportive of aggressive behavior and conventional rule-violating behavior. However, gender differences in beliefs and values were greater for aggressive acts than for conventional acts. The results support the need to distinguish between behavioral domains when attempting to predict social behavior. Aggr. Behav. 24:347–365, 1998. © 1998 Wiley-Liss, Inc.     

Effect of body size on aggression in the ant,Cataglyphis niger (Hymenoptera; Formicidae)

In polymorphic ants, such as Cataglyphis niger, sterile individual workers from the same nest show some degree of variation in size and/or morphology. We studied whether worker size and size difference between opponents had an effect on aggression during conspecific encounters. Although the capacity to recognize nestmates was shared by all individuals, some patterns of agonistic behaviors were size related. Escape was mostly displayed by the small workers, and threat, associated with ritualized fights, by the large workers. As game theory predicted, ants of C. niger adjusted their level of aggression as a function of the size of the opponent. However, only large individuals used such assessment strategies, responding with escalation of aggression towards small workers and reduction of aggression towards large ones. On the contrary, small individuals behaved in the same manner whatever the opponent's size. Differences between both morphological castes were discussed with reference to the resource holding assessment models. Aggr. Behav. 25:369–379, 1999. © 1999 Wiley‐Liss, Inc.     

Decision-making competence in everyday life: The roles of general cognitive styles,decision-making styles and personality

Research indicates that decision-making competence in everyday life is associated with certain decision-making styles. The aims of this article are to extend this research by examining (a) the extent to which general cognitive styles explain variance in decision-making competence over and above decision-making styles, and (b) the extent to which personality explains variance in decision-making competence over and above both types of style variable. Participants (N = 355) completed measures of everyday decision-making competence (Decision Outcomes Inventory), decision styles (Decision Style Questionnaire; Maximization Inventory), cognitive styles (the Cognitive Styles Inventory; Rational-Experience Inventory), and the Big Five personality variables (IPIP Big-Five factor scales). The results indicate that cognitive styles offer no incremental validity over decision-making styles in predicting decision-making competence, but that personality does offer substantial incremental validity over general cognitive styles and decision-making styles. Jointly decision-making styles and personality account for a substantial amount of variance in everyday decision-making competence.     

Short‐term and working memory: Past,progress, and prospects

Abstract

The role of current personal experience in understanding of word meaning was investigated in a patient, WM, who suffers from semantic dementia. The study was prompted by the observation that WM, despite being severely impaired on formal tests of word comprehension and naming, retained a range of vocabulary pertaining to her daily life. If autobiographical experience has a general facilitatory effect, then this should affect which concepts are retained and which lost, but not influence the quality of that conceptual knowledge. Conversely, if personal autobiography has a direct role in investing concepts with meaning, then WM's understanding of nominal terms that she uses spontaneously in conversation ought not to be normal, but should be constrained by the autobiographical context in which she uses those terms. WM could define nouns and noun phrases drawn from her conversational vocabulary, but her definitions had a markedly autobiographical quality. Moreover, WM was extremely impaired in her ability to define new noun phrases, constructed by combining words from her conversational vocabulary (e.g. “dog licence”, constructed from “driving licence” and “dog” “oil field” constructed from “oil” and “field”). It was concluded that WM does not have normal conceptual understanding of nouns and noun phrases that she uses appropriately in conversation. Her understanding is narrow and autobiographically constrained. The findings, which suggest an interactive relationship between autobiographical and semantic memory, have implications for understanding of the progressive breakdown of semantic knowledge.     

Prospective and concurrent correlates of emotion perception in psychotic disorders: A naturalistic,longitudinal study of neurocognition,affective blunting and avolition

This naturalistic study investigated longitudinal and cross‐sectional symptomatic and neurocognitive correlates of social cognition indexed by emotion perception. Participants were 31 persons admitted to a psychiatric emergency ward due to acute psychosis. Positive and negative (i.e., affective blunting and avolition) symptoms were assessed at baseline and 12‐month follow‐up using the Positive and Negative Syndrome Scale. Participants completed neuropsychological assessments with alternative versions of the Repeatable Battery for the Assessment of Neuropsychological Status at baseline and at 12‐month follow‐up. Emotion perception was measured using the Face/Voice Emotion Test at 12‐month follow‐up. Correlational analyses (Spearman's rho) revealed strong and statistically significant associations between neurocognition and emotion perception (baseline r = 0.58, follow‐up r = 0.43). Associations between positive symptoms and emotion perception were weak or non‐existent (baseline r = 0.13, follow‐up r  =  –0.01). Emotion perception was moderately, but not significantly, associated with affective blunting at follow‐up (r = 0.33), but not at baseline (r = 0.21). The association with avolition was non‐existent (baseline r  =  –0.05, follow‐up r = 0.01). This study supports the notion that emotion perception has neurocognitive correlates. The cross‐sectional trend level association with affective blunting suggests that the ability to perceive emotions might be related to, but dissociable from the ability to express emotions.     

Intending to Leave But No Place to Go: An Examination of the Behaviors of Reluctant Stayers

We extend recent conceptual work on withdrawal states and develop a framework to examine behavioral tendencies of reluctant stayers (i.e., employees who desire to leave but cannot). Although principles of self-interest suggest that these employees ought to behave appropriately to maintain employment, reactance theory suggests that the combination of high turnover intentions and low job alternatives may result in lower performance and greater deviance. Contrary to conventional wisdom but consistent with reactance theory, low perceived job alternatives strengthened the positive relationship between turnover intentions and deviance, as well as the negative relation between intentions to quit and task performance. Moderated-mediation analyses revealed that the indirect effect of work frustration (via turnover intentions) was stronger on task performance and deviance when perceived job alternatives were low rather than high.     

Remembering specific features of emotional events across time: The role of REM sleep and prefrontal theta oscillations

When an episode of emotional significance is encountered, it often results in the formation of a highly resistant memory representation that is easily retrieved for many succeeding years. Recent research shows that beyond generic consolidation processes, rapid eye movement (REM) sleep importantly contributes to this effect. However, the boundary conditions of consolidation processes during REM sleep, specifically whether these extend to source memory, have not been examined extensively. The current study tested the effects of putative consolidation processes emerging during REM sleep and slow wave sleep (SWS) on item and source memory of negative and neutral images, respectively. Results demonstrate superior emotional relative to neutral item memory retention after both late night REM sleep and early night SWS. Emotional source memory, on the other hand, exhibited an attenuated decline following late night REM sleep, whereas neutral source memory was selectively preserved across early night SWS. This pattern of results suggests a selective preservation of emotional source memory during REM sleep that is functionally dissociable from SWS-dependent reprocessing of neutral source memory. This was further substantiated by a neurophysiological dissociation: Postsleep emotional source memory was selectively correlated with frontal theta lateralization (REM sleep), whereas postsleep neutral item memory was correlated with SWS spindle power. As such, the present results contribute to a more comprehensive characterization of sleep-related consolidation mechanisms underlying emotional and neutral memory retention. Subsidiary analysis of emotional reactivity to previously encoded material revealed an enhancing rather than attenuating effect of late night REM sleep on emotional responses.
