The mutual influence of insulin and environmentally-conditioned central nervous system performance on the regulation of carbohydrate metabolism

Investigating the effects of insulin on carbohydrate metabolism and on the central nervous system (C.N.S.) under conditions of rest and of stress in dogs and in rats, using the conditional reflex method and measuring the nitrogen and phosphate brain metabolites and the blood sugar differences, the author found that cerebral glucose metabolism is dependent upon insulin, and that if glucose supplies are adequate, insulin stimulates C.N.S. performance within 15–20 minutes. The C.N.S. and blood sugar reactivity depend upon the environmental situation: the conditional stimuli for stress increase glycemia. Animals under stress went into shock even though their glycemic levels were relatively high, whereas those at rest did not go into shock or sometimes reacted with slight symptoms of somnolence even at a lower glycemic level. In experimental hyperglycemia the level rises even more during stress, with ensuing coma, especially with larger doses of insulin. An increase of inhibition with reduced learning precedes the glycemic irregularities. Thus, insulin directly influences the central nervous system.     

Reactions to self-discrepant feedback: Feminist attitude and symbolic self-completion

Reactions to self-discrepant feedback were theoretically and experimentally investigated. The conceptual frame was provided by the theory of symbolic self-completion. Starting from the assumption that attitudes can function as central aspects of self-definition, 81 female subjects were either presented with feedback that their attitudes were unfeminist (treatment, i.e. incompleteness condition) or they received no feedback (control condition) Then they were given the opportunity for self-symbolizing by subscribing to a feminist journal. Subjects with strongly pro-feminist attitudes who were made incomplete with respect to their feminist self-definition subscribed more often and more intensively to the feminist journal than others. The results illustrate that attitudes can take on the character of self-definitions. Furthermore, reactions to self-discrepant feedback concerning a central attitude were as predicted by the theory of symbolic self-completion.     

Patterns of self-initiated smoking cessation among young adults

Prochaska and DiClemente's (1984) cyclic-stage model of self-initiated smoking cessation divides the cessation process into five stages. This model was applied to a young adult population to determine the cross-sectional distribution of stages and the frequency and pattern of changes among stages over time. Compared to older adults, the distribution of the stages differed substantially: There were twice as many relapsers and only half as many maintainers among young adults. One-year changes in stages were examined using a static model, which did not take into account the cyclic nature of the change process, and a more realistic dynamic model, which did. Both models, especially the dynamic model, suggested substantially more movement among stages in younger than in older adults.

Automatic identification of storytelling responses to past-behavior interview questions via machine learning

Structured interviews often feature past-behavior questions, where applicants are asked to tell a story about past work experience. Applicants often experience difficulties producing such stories. Automatic analyses of applicant behavior in responding to past-behavior questions may constitute a basis for delivering feedback and thus helping them improve their performance. We used machine learning algorithms to predict storytelling in transcribed speech of participants responding to past-behavior questions in a simulated selection interview. Responses were coded as to whether they featured a story or not. For each story, utterances were also manually coded as to whether they described the situation, the task/action performed, or results obtained. The algorithms predicted whether a response features a story or not (best accuracy: 78%), as well as the count of situation, task/action, and response utterances. These findings contribute to better automatic identification of verbal responses to past-behavior questions and may support automatic provision of feedback to applicants about their interview performance.     

The World According to Men: It Is Hierarchical and Stereotypical

The present research was designed to test whether people who expect social relationships to be structured like pecking orders (interpersonal hierarchy expectation, IHE) are also prone to stereotyping and whether this relation is moderated by gender. In two studies, a total of 203 participants completed a self-report questionnaire on IHE (Interpersonal Hierarchy Expectation Scale, IHES) and either a questionnaire that measures a general tendency to stereotype (Acceptance of Stereotyping Questionnaire, ASQ, Study 1) or a projective measure that assesses the specific gender stereotype that low dominance positions are occupied by women and high dominance positions by men (Study 2). Results showed that both stereotyping measures were related to IHE, but only for men. Moreover, trait dominance did not mediate the relation between IHE and stereotyping.     

Drawn towards what others seem to like: Implicit preference for objects and people looked at with a duchenne smile

People tend to like objects that are looked at by others, especially if the person looking at the object expresses a positive emotion. But not all positive emotions are equal. We investigated the effect of third party gazing while expressing subtle positive emotions on perceivers’ subsequent preferences and evaluations of objects and people. In two studies participants saw faces looking at target objects and people either with a Duchenne, a non-Duchenne smile, or a neural expression. Participants first indicated gaze direction and later reported intuitive target preference and evaluated the targets. Results show a preference for target stimuli that were smiled at with a Duchenne smile as opposed to when they were looked at with a non-Duchenne smile or a neutral expression. More explicit evaluations of the target stimuli were not affected by the type of facial expression.     

Political Violence and Psychological Well-Being: The Role of Social Identity

A significant body of research points to the central role of identity in creating and maintaining conflict. However, less research has focused on the protective role of social identity in such situations. Using a survey sample of 3,000 participants, 2,000 of whom were resident in a conflict-affected region (Northern Ireland) and 1,000 in a region more distally affected (the Border counties of the Republic of Ireland) the potential moderating and mediating impact of national identification on the relationship between direct and indirect experience of political violence and psychological well-being is examined. Findings indicate that national identification mediates the impact of direct political violence on well-being in Northern Ireland. This relationship is strongest where preferred nationality is relevant to the social division underlying the conflict. Those more distally affected, resident in the Republic of Ireland, did not evidence this pattern of relationships. Discussion of results focuses on the potential positive and negative implications of these findings for personal and societal well-being, respectively.     

The dissemination of critical,unshared information in decision‐making groups: the effects of pre‐discussion dissent

Previous research in group decision making has found that in situations of a hidden profile (i.e. the best choice alternative is hidden from individual members as they consider their pre‐discussion information), unshared information is disproportionately neglected and sub‐optimal group choices are highly likely. In an experimental study, three‐person groups decided which of three candidates to select for a professorial appointment. We hypothesised that minority dissent in pre‐discussion preferences improves the consideration of unshared information in groups and increases the discovery rate of hidden profiles. As predicted, consideration of unshared information increased with minority dissent. The expectation of an improvement of group decision quality was partially supported. In diversity groups (i.e. each member prefers a different alternative) consideration of unshared information and group decision quality was significantly higher than in simple minority groups. Results are discussed in the light of theories of minority influence. The benefits of using the hidden profile paradigm with minority and diversity groups for theory development in the area of group decision making are highlighted.
