Improving work motivation and performance in brainstorming groups: The effects of three group goal-setting strategies

An experiment was conducted with 30 groups (n = 120) solving brainstorming tasks under four different group goal conditions: do your best (DYB), directive group goal setting (DGGS), participative group goal setting (PGGS), and PGGS in combination with individual goal setting (PGGS + IGS). As expected, all groups with specific and difficult group goals performed better than DYB control groups. It is hypothesized that these positive effects of group goal setting on brainstorming performance arise because group goal setting counteracts motivation losses such as social loafing. In addition, group goal setting should promote motivation gains arising from social compensation and related cognitive processes, in particular high identification with the group. Consistent with this hypothesis, it was found that group goal setting increased team identification, the readiness to compensate for other weak group members, the value of group success, and the value of group failure. Mediation analysis also indicated that concern to avoid group failure was partly responsible for performance improvements. Finally, no large differences were found between PGGS + IGS and PGGS or DGGS. On this basis group goal setting can be considered a robust strategy for improving work motivation and brainstorming performance in groups.     

Intact emotion–cognition interaction in schizophrenia patients and first-degree relatives: Evidence from an emotional antisaccade task

Schizophrenia patients have deficits in cognitive control as well as in a number of emotional domains. The antisaccade task is a measure of cognitive control that requires the inhibition of a reflex-like eye movement to a peripheral stimulus. Antisaccade performance has been shown to be modulated by the emotional content of the peripheral stimuli, with emotional stimuli leading to higher error rates than neutral stimuli, reflecting an implicit emotion processing effect. The aim of the present study was to investigate the impact on antisaccade performance of threat-related emotional facial stimuli in schizophrenia patients, first-degree relatives of schizophrenia patients and healthy controls. Fifteen patients, 22 relatives and 26 controls, matched for gender, age and verbal intelligence, carried out an antisaccade task with pictures of faces displaying disgusted, fearful and neutral expressions as peripheral stimuli. We observed higher antisaccade error rates in schizophrenia patients compared to first-degree relatives and controls. Relatives and controls did not differ significantly from each other. Antisaccade error rate was influenced by the emotional nature of the stimuli: participants had higher antisaccade error rates in response to fearful faces compared to neutral and disgusted faces. As this emotional influence on cognitive control did not differ between groups we conclude that implicit processing of emotional faces is intact in patients with schizophrenia and those at risk for the illness.     

Associations between type of treatment and illness-specific locus of control in type 1 diabetes patients

Abstract

This study examined differences in diabetes-specific locus of control beliefs of 82 insulin-treated Type I diabetes patients undergoing either conventional therapy (CT), intensified conventional therapy (ICT) or continuous subcutaneous insulin infusion (CSII). Compared to CT with its adherence to a strict regimen, ICT and CSII allow a much greater flexibility in timing of meals and daily activities. On the other hand, such flexibility requires a much more active role of the patient. The hypotheses of higher internality and lower powerful others locus of control beliefs in ICT and CSII patients than in CT patients could be supported for powerful others locus of control only. A one-year follow-up replicated this finding. Furthermore, high powerful others locus of control was associated with low diabetes-related knowledge and poor glycaemic control. The relevance of the patients' experience with the respective treatment is examined in view of the results and implications for studies on the feasibility of diabetes regimens are discussed.     

The role of risk perception and efficacy cognitions in the prediction of HIV-related preventive behavior and condom use

Abstract

Based on empirical findings on the central model variables of the Protection Motivation Theory, the influence of perceived susceptibility, perceived severity of the threat of AIDS, communicative and sexual self-efficacy, and outcome expectancy on various aspects of HIV-preventive behavior was examined. The study was based on a sample of 468 heterosexual adults between the ages of 20 and 45 years. The data were obtained by means of questionnaires filled out at various vacation sites that draw mass tourism or in the subjects' home town. The most significant predictor of behavior was found to be self-efficacy expectancy as regards assertiveness and use of HIV-related preventive measures. A high communicative self-efficacy expectancy, on the other hand, is associated with a higher level of risk behavior among certain subgroups and under certain behavioral aspects. This confirms the necessity of acknowledging the different forms of self-efficacy expectancy in sexual interactions. Perceived personal threat is also associated with risk behavior with respect to certain behavioral operationalizations. From this it can be concluded that one's own behavior is used as the basis for appraising one's susceptibility. The results also show that distinctions must be made when analyzing HIV-related risk behavior. In particular, a difference must be made between absolute behavior (degree of the risk behavior) and relative behavior (change - especially reduction - in risk behavior due to the danger of AIDS).     

Expected car use reduction in response to structural travel demand management measures

Selecting the appropriate travel demand management (TDM) measures aiming to reduce the environmental problems associated with private transportation demands a thorough understanding of the behavioral consequences of different measures. In this scenario based study, the expected car use reduction in response to one push measure (i.e. raised tax on fossil fuel), one pull measure (i.e. improved public transport), and a combination of the two measures were analyzed. The aim was to compare the expected car use reduction in response to the different TDM measures, the car use reduction strategies used to achieve this reduction, and factors important for the expected car use reduction (i.e. background factors, internal motivational factors (general intention and personal norm), and perceived personal impact of the measure). In a two step between-subject design, a sample of car users first answered a pre-questionnaire and subsequently three groups of car users (N = 274) each evaluated one of the TDM measures. Results demonstrated that the combined measure led to larger expected car use reduction compared to the measures evaluated individually and the reduction was mainly expected to be made by means of trip chaining and changing travel mode. Moreover, internal motivational factors, such as personal norm or general intention, and the perceived impact of the measure, were found to be important for the expected car use reduction in response to the TDM measures.     

Repression-sensitization,gender, and discrepancies in psychobiological reactions to examination stress

Psychobiological responses to examination stress in repressors and sensitizers have rarely been investigated with respect to intraindividual response discrepancies. Furthermore, possible sex differences have rarely been taken into consideration. Therefore the present study investigated if repressors and sensitizers differ in their psychobiological responses to stress and if gender plays a modulating role. 30 and 29 students of both sexes selected from a total group of 96 students were classified as repressors or sensitizers each according to the repression-sensitization-coping-inventory (RSCI, Huwe et al.). State anxiety, heart rate, and cortisol in saliva served as indicators of stress. Sensitizers reported higher state anxiety and showed higher physiological stress responses than repressors. On the intraindividual level sensitizers reported high anxiety as compared to their low cortisol responses whereas repressors reported low anxiety as compared to their high cortisol increases. Gender had no modulating influence on stress responses in repressors and sensitizers.
