Peer Leadership in Sport: Links with Friendship,Peer Acceptance,Psychological Characteristics,and Athletic Ability

The purpose of this study was to replicate and extend the work of Glenn and Horn (1993) Glenn, S. D. and Horn, T. S. 1993. Psychological and personal predictors of leadership behavior in female soccer athletes. Journal of Applied Sport Psychology, 5: 17–34. [CSA][Taylor & Francis Online] , [Google Scholar] by examining relationships between peer leadership in sport and social, psychological, and ability characteristics. The sample consisted of 71 female and 67 male high-school soccer players and their coaches. Players completed questionnaires measuring social (peer acceptance and friendship quality) and psychological (perceived competence, instrumentality, and expressiveness) variables, and leadership behavior for self and teammates. Coaches assessed each player on leadership behavior and soccer ability. For female athletes, all psychosocial variables were predictive of self-ratings of leadership, while coach and teammate ratings were related to ability only. For male athletes, all psychosocial variables and ability were related to self-ratings and teammate ratings of peer leadership, while coaches' ratings were related primarily to ability. These results are discussed with regard to social exchange theory and commonalities among peer relationship variables (acceptance, friendship, leadership).     

Neither justice nor charity? Kant on ‘general injustice’

We often make a distinction between what we owe as a matter of repayment, and what we give or offer out of charity. But how shall we describe our obligations to fellow citizens when we are in a position to be charitable because of a past injustice on the part of the state? This essay examines the moral implications of past injustice by considering Immanuel Kant’s remarks on this phenomenon in his lectures and writings. In particular, it discusses the role of the state and the individual in addressing the problem.     

Creating false memories for brand names

Using the Deese–Roediger–McDermott (DRM) paradigm, participants are presented with lists of associated words (e.g., bed, awake, night etc). Subsequently, they reliably have false memories for related but non‐presented words (e.g. SLEEP). The present study investigated whether false memories could be created for brand names (e.g. Morrisons, Sainsbury's, Waitrose and TESCO) using the DRM paradigm and whether the effect was reduced if stimuli were presented in brand appropriate fonts compared with a plain font. Participants were presented with lists of brand names in plain or brand appropriate fonts, followed by a distractor task or free recall. Finally, they had a recognition task. Both false recall and false recognition of non‐presented brand names occurred. Brand specific fonts at study had no effect on recall but increased overall recognition. There was considerable variability in levels of false recall and false recognition amongst lists and across participants and reasons for this are discussed.

Mind your errors: evidence for a neural mechanism linking growth mind-set to adaptive posterror adjustments

How well people bounce back from mistakes depends on their beliefs about learning and intelligence. For individuals with a growth mind-set, who believe intelligence develops through effort, mistakes are seen as opportunities to learn and improve. For individuals with a fixed mind-set, who believe intelligence is a stable characteristic, mistakes indicate lack of ability. We examined performance-monitoring event-related potentials (ERPs) to probe the neural mechanisms underlying these different reactions to mistakes. Findings revealed that a growth mind-set was associated with enhancement of the error positivity component (Pe), which reflects awareness of and allocation of attention to mistakes. More growth-minded individuals also showed superior accuracy after mistakes compared with individuals endorsing a more fixed mind-set. It is critical to note that Pe amplitude mediated the relationship between mind-set and posterror accuracy. These results suggest that neural mechanisms indexing on-line awareness of and attention to mistakes are intimately involved in growth-minded individuals' ability to rebound from mistakes.     

Involuntary strategy-dependent dual task performance

Previous studies showed that some dual tasks can be performed simultaneously without costs. Yet, a variable SOA between the inputs to such tasks leads to strategic, often involuntary, prioritization of one of the two tasks. Here we explore the boundary conditions for this involuntary or exogenous strategy. In Experiment 1, subjects were initially trained on dual task performance where the input to the two tasks is presented simultaneously (0 SOA). We used two tasks that under such conditions can be performed without costs and indeed subjects displayed perfect sharing of the tasks. Subjects then performed the same two tasks but with a variable SOA (0, 50, 150, 800?ms). This manipulation led to a serial-like performance of the two tasks even in trials with 0 SOA. In Experiment 2, subjects participated in eight sessions. Within each session, they performed in alternation blocks with a fixed 0 SOA and blocks with a variable SOA. Subjects displayed perfect sharing in the pure 0 SOA blocks but performed the two tasks serially in the mixed SOA blocks despite receiving identical instructions. These findings demonstrate that task context is a powerful factor in dual task performance and may lead subjects to involuntarily exhibit dual task costs even in conditions where they can perform the tasks without any costs. Moreover, these findings strongly suggest that costs observed in PRP studies reflect the use of such exogenous strategies rather than a general structural dual task limitation.     

Receiving advice on matters of taste: Similarity, majority influence, and taste discrimination

People routinely consider the opinions of others prior to making decisions on matters of taste (e.g., a restaurant or movie). Our theoretical framework highlights the role of two sources, social (majority) influence and similarityamong advisors, in such decisions. We suggest that individuals’ use of these sources depends on their taste discrimination. While highly discriminating judges seek the opinion of a similar advisor rather than the majority opinion, less discriminating judges do so less. In four studies participants made musical choices based on recommendations. The studies document the great appeal of behavioral similarity and the role of demographic similarity. They also provide evidence for the discrimination hypothesis. A formal simulation is developed to account for the relationship between taste discrimination and the predictive accuracy of the majority and of similar advisors. The results shed light on theories of advice utilization and social influence, and are connected with applications involving personalized recommendation systems.
