Age influences domestic dog cognitive performance independent of average breed lifespan

Animal Cognition - Across mammals, increased body size is positively associated with lifespan. However, within species, this relationship is inverted. This is well illustrated in dogs (Canis...     

Self-Regulation and Personality Science: Reply to the Commentaries

The authors reply to commentaries on their target article "Self-Regulation: Reminders and Suggestions from Personality Science". Substantial consensus is evident across the target article and multiple commentaries. The message conveyed is that personality science and the study of self-regulation are mutually complementary and that applied efforts to enhance people's self-regulatory capacities can be enhanced via study of the intra-individual architecture of social-cognitive and affective personality systems.     

Mandel'štam and Dante: TheDivine Comedy in Mandel'štam's poetry of the 1930s

Osip Mandel'?tam (1891–1938?) belongs among the greatest Russian poets of the twentieth century. During the thirties, when he led a tragic existence and felt a premonition of his inevitable violent death, Mandel'?tam saw in Dante not only the greatest poet, but also his own superior teacher, and his poems of that period contain a tormented meditation on the masterpiece of Dante's genius — theDivine Comedy. Epic poetry of Dante, Homer, Virgil and others was possible because the inner world of each poet was essentially at one with the ethos of the society in which he lived. Mandel'?tam's inner world was Judaeo-Christian, European, and rooted in classical and neo-Platonic philosophy, but his outer world, consisting of a new Marxist or pseudo-Marxist system, was totally at odds with it. Thus Mandel'?tam could not embody the epic impulse of the society he opposed. He was left with the tormented lyric impulse. The fundamental conflict between Mandel'?tam as a lyric poet and the society in which he had to live and work accounts for the fact that his vision of Stalinist society in a number of respects remarkably corresponds to Dante's vision of a perverted divine order in theInferno.     

Type A Behavior and Diabetic Control: Implications of Psychological Reactance for Health Outcomes1

According to laboratory research, Type A coronary-prone individuals are sensitive to threats to their personal control and react to such threats with active and often stressful coping responses. The present investigation tested the prediction that these features of Type A behavior would interfere with blood glucose regulation in insulin-dependent diabetes mellitus patients. Two independent hypotheses were investigated. Because elevated sympathetic arousal, a concomitant of stressful coping, is associated with elevated glucose levels, it was predicted that Type A diabetics experiencing high levels of life stress would display poorest blood glucose control (indexed by Hemoglobin A₁c). The second hypothesis was derived from the observation that Type As are more likely than Type Bs to respond to control threats with reactance in order to restore the perception of control. Given that illness or treatment can reduce personal control, it was predicted that Type A diabetics would be most reactant and, thus, most medically noncompliant. To test these hypotheses, 37 Type 1 diabetics were assessed for Type A behavior, life change, attributional style, desire for control (both within treatment and in general), and specific perceptions of and actions to their diabetes. Type As were more likely than Type Bs to show poor blood glucose control. However, for patients in general, and Type As in particular, blood glucose regulation was not related to life stress. Rather, those Type As who displayed poor glucose control made more extreme self-attributions about the cause of their diabetes, were angrier about it, and felt they should fight it. The implications of these findings for a reactance-Type A model of medical compliance are discussed.     

It ain’t over ‘til it’s over: The effect of task completion on the savoring of success

The present research investigated a common yet to date unexamined assumption that individuals are unlikely to savor success when they have not yet fully completed a task. In Study 1 (N = 83), we assessed savoring responses of soccer players who were either winning or were tied at the end of the first half (in progress) and at the end of the match (completed). In Study 2 (N = 121 undergraduates), performance feedback (successful vs. average) and task completion (in progress vs. completed) were manipulated and savoring was assessed. In both studies, successful individuals reported savoring their positive experience less when the task was in progress as compared to completed. Results of a third study (N = 152 undergraduates) showed that lower savoring of success was due to individuals’ focus on and worries about future performance as well as the perception that positive emotions have limited utility. We discuss these findings in terms of the consequences for performance and well-being.     

Coping Strategies and Resolution in Mothers of Children With Cerebral Palsy

“Parental resolution” represents parents coming to terms with their child’s health condition. Differences in the use of coping strategies between mothers who were resolved versus unresolved to their child’s diagnosis was investigated, and a possible moderating effect of these strategies was explored. A strategy aimed at mobilizing the family to acquire and accept help (institutional, formal support) was shown to be a significant moderating variable, in a way that its more frequent use allowed mothers of children with better functional status (but not mothers of children with poorer functional status) to reach resolution.     

On the automaticity of emotion processing in words and faces: event-related brain potentials evidence from a superficial task

The degree to which emotional aspects of stimuli are processed automatically is controversial. Here, we assessed the automatic elicitation of emotion-related brain potentials (ERPs) to positive, negative, and neutral words and facial expressions in an easy and superficial face-word discrimination task, for which the emotional valence was irrelevant. Both emotional words and facial expressions impacted ERPs already between 50 and 100 ms after stimulus onset, possibly reflecting rapid relevance detection. Following this initial processing stage only emotionality in faces but not in words was associated with an early posterior negativity (EPN). Therefore, when emotion is irrelevant in a task which requires superficial stimulus analysis, automatically enhanced sensory encoding of emotional content appears to occur only for evolutionary prepared emotional stimuli, as reflected in larger EPN amplitudes to faces, but not to symbolic word stimuli.     

Psychometric properties of the Social Skills Questionnaire: Portuguese adaptation of the student form (grades 7 to 12)

The present study aims to analyze the psychometric properties of the student form (Grades 7 to 12) of the Social Skills Questionnaire authored by Gresham and Elliott (1990), on a sample of Portuguese adolescents. Participants included 573 students, both female and male, aged 14 to 19. Reliability was assessed through Cronbach's alpha and was .87 for the total scale, ranging from.58 to .72 for the subscales. A confirmatory factor analysis revealed that the main adjustment indices presented unexpected values. A principal components analysis indicated that several items of the cooperation subscale correlated with other factors. Adequate adjustment indices were found when cooperation was removed from the model. Semantic dualities due to cultural factors and difficulties assuming the cooperation dimension as an independent dimension might explain the results observed. The reorganization of the SSQ offers a reliable and valid instrument for research within the Portuguese population.     

Un regard structural sur l’inégalité des genres au travail : La causalité des différences « genrées » dans les caractéristiques de réseau de l’employé

This study aims at identifying gender differences in network structure and, hence, at understanding the underlying nature of gender inequalities in organisations. The hypotheses address four ego-network characteristics: network size and density, and ego’s centrality and brokerage. Contrary to the existing body of literature, none significant isolated gender difference in network structure is identified. Instead, those gender differences are triggered exclusively by organisational status, that is to say, they are due to the increased level of power. Thus, organisational status is considered as moderating the relationship between gender and network structure’s characteristics. Some further perspectives are suggested to clarify and generalise the phenomena observed.
