The shared leadership process in decision-making teams

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership.     

Psychological constructionism and cultural neuroscience

Lindquist et al. argue that emotional categories do not map onto distinct regions within the brain, but rather, arise from basic psychological processes, including conceptualization, executive attention, and core affect. Here, we use examples from cultural neuroscience to argue that psychological constructionism, not locationism, captures the essential role of emotion in the social and cultural brain.     

Interactive voice response for relapse prevention following cognitive-behavioral therapy for alcohol use disorders: a pilot study

Relapse after alcoholism treatment is high. Alcohol Therapeutic Interactive Voice Response (ATIVR) is an automated telephone program for posttreatment self-monitoring, skills practice, and feedback. This pilot study examined feasibility of ATIVR. Participants (n = 21; 57% male) had access to ATIVR for 90 days following outpatient group cognitive-behavioral therapy (CBT) to make daily reports of mood, confidence in sobriety, urges to use substances, and actual use. Reports of relapse or risk were followed with additional questions. Participants received personalized therapist feedback based on responses, and could access recorded CBT skill reviews. Pre-post assessments included: alcohol consumption (Timeline Follow-Back), self-efficacy (Situational Confidence Questionnaire), and perceived coping ability (Effectiveness of Coping Behaviors Inventory). Participants called on 59% of scheduled days and continued making calls for an average of 84 days. Following ATIVR, participants gave feedback that ATIVR was easy to use and increased self-awareness. Participants particularly liked the therapist feedback component. Abstinence rate increased significantly during ATIVR (p = .03), and both self-efficacy and coping significantly improved from pre-CBT to post-ATIVR (p < .01). Results indicate ATIVR is feasible and acceptable. Its efficacy should be evaluated in a randomized controlled trial.     

Commitment to a developing preference and predecisional distortion of information

People tend to distort their evaluation of decision-relevant information in favor of the currently preferred alternative. We test whether this predecisional distortion of information is amplified by increased commitment to that current preference. We manipulated commitment, without changing the preferred option’s content, by requiring participants to indicate their preference either by circling or by darkening a sizable box (cf. feature-positive effect). Experiment 1 revealed that the effort to darken substantially increased predecisional distortion. Experiment 2 ruled out elaboration as an explanation for the effect of darkening. Experiment 3 showed that, among participants who attributed the darkening effort to an external source, predecisional distortion decreased when the source was believed to summon effort. These findings suggest that the developing commitment to a tentatively preferred alternative is one driver of predecisional distortion.     

Role of the dorsal hippocampus in object memory load

The dorsal hippocampus is crucial for mammalian spatial memory, but its exact role in item memory is still hotly debated. Recent evidence in humans suggested that the hippocampus might be selectively involved in item short-term memory to deal with an increasing memory load. In this study, we sought to test this hypothesis. To this aim we developed a novel behavioral procedure to study object memory load in mice by progressively increasing the stimulus set size in the spontaneous object recognition task. Using this procedure, we demonstrated that naive mice have a memory span, which is the number of elements they can remember for a short-time interval, of about six objects. Then, we showed that excitotoxic selective lesions of the dorsal hippocampus did not impair novel object discrimination in the condition of low memory load. In contrast, the same lesion impaired novel object discrimination in the high memory load condition, and reduced the object memory span to four objects. These results have important heuristic and clinical implications because they open new perspective toward the understanding of the role of the hippocampus in item memory and in memory span deficits occurring in human pathologies, such as Alzheimer's disease and schizophrenia.     

Human values in the team leader selection process

The selection process of team leaders is fundamental if the effectiveness of teams is to be guaranteed. Human values have proven to be an important factor in the behaviour of individuals and leaders. The aim of this study is twofold. The first is to validate Schwartz's survey of human values. The second is to determine whether there are any relationships between the values held by individuals and their preferred roles in a team. Human values were measured by the items of the Schwartz Value Survey (SVS) and the preferred roles in a team were identified by the Belbin Self Perception Inventory (BSPI). The two questionnaires were answered by two samples of undergraduate students (183 and 177 students, respectively). As far as the first objective is concerned, Smallest Space Analysis (SSA) was performed at the outset to examine how well the two-dimensional circular structure, as postulated by Schwartz, was represented in the study population. Then, the results of this analysis were compared and contrasted with those of two other published studies; one by Schwartz (2006) and one by Ros and Grad (1991). As for the second objective, Pearson correlation coefficients were computed to assess the associations between the ratings on the SVS survey items and the ratings on the eight team roles as measured by the BSPI.     

Perceived coach-autonomy support, basic need satisfaction and the well- and ill-being of elite youth soccer players: A longitudinal investigation

Objectives

Drawing from the basic needs theory [BNT; Ryan, R. M., & Deci, E. L. (2002). An overview of self-determination theory. In E. L. Deci, & R. M. Ryan (Eds.), Handbook of self-determination research (pp. 3-33). Rochester, NY: University of Rochester Press], the major purpose of the present study was to test a hypothesized sequence of temporal relationships between perceptions of coach-autonomy support, basic need satisfaction and indices of well- and ill-being. A subsidiary aim was to ascertain the assumed mediational role of basic need satisfaction in explicating the perceived autonomy support and well-/ill-being relationships over time.

Design

A field-based longitudinal design was employed.

Methods

Participants (N = 54 males) from an elite youth soccer academy in the UK completed a multi-section questionnaire tapping the targeted variables on six occasions across two competitive seasons.

Results

Multi-level regression analyses revealed that perceptions of coach-autonomy support positively predicted within-person changes and between-person mean differences in basic need satisfaction and well-being over time. Satisfaction scores for the needs for competence and relatedness were found to predict within-person changes in subjective vitality. These same needs partially mediated the coach-autonomy support-subjective vitality link over the two seasons.

Conclusions

The findings partially support the tenets of BNT, and are discussed in terms of their practical application to participants involved in an elite youth sport setting.     

The psychosocial impact of multiple sclerosis: exploring the patient's perspective.

This study examined subjective patient experiences of the psychosocial consequences of multiple sclerosis (MS). Fifty patients were interviewed regarding the effects MS had on their lives and interpersonal relationships. These statements were collated and administered with a 5-point Likert scale to 94 MS patients. The responses were subjected to factor analysis. Three areas of subjective patient experience of the psychosocial consequences of MS emerged: demoralization, benefit-finding, and deteriorated relationships. Of particular interest was benefit-finding, which included a deepening of relationships, enhanced appreciation of life, and an increase in spiritual interests. Although benefit-finding was related to adaptive coping strategies such as positive reappraisal and seeking social support, it was unrelated to depression and was related to higher levels of anxiety and anger. These findings indicate that benefit-finding is a substantial and poorly understood part of the illness experience for MS patients.     

Computing: Is it a better mousetrap?

In the spring of 1983, Drexel University announced that all incoming freshmen the following fall would be required to have access to a personal computer being designed by Apple. This paper reports on the impact of that decision over the next 2 years.
