Perceived inclusion in youth soccer teams: The role of societal status and perceived motivational goal climate

ObjectivesOur aim was to investigate the link between youth soccer players' perceptions of the coach-initiated motivational goal climate within their team and their perceptions of inclusion as a function of societal status. Societal status refers to one's national background which numerically forms the majority or a minority in a particular society.Design and methodsSurvey data was collected among 245 male youth soccer players (M = 12.9 years, SD = 1.60), who all played in culturally diverse teams in the Netherlands. The societal status of 94 players (38.4%) was majority, and 151 players (61.6%) were classified as minority. To test our main hypothesis, perceived inclusion as the dependent variable was hierarchically regressed on coach-initiated mastery goal climate perceptions, performance goal climate perceptions, societal status, and their interactions.ResultsOverall, mastery goal perceptions and performance goal perceptions of intra-team competition were positively and negatively related, respectively, to perceived team inclusion. As hypothesized, only among players with a societal minority status, perceptions of inclusion were higher when mastery goal climate perceptions were higher and performance goal climate perceptions were lower.Discussion and conclusionOur findings suggest that a coach-initiated mastery-oriented team climate may enhance an inclusive soccer environment in culturally and nationally diverse teams. For societal minority players, intra-team competition should be de-emphasized by the coach in order to strengthen the experience of inclusion.     

Social Behaviors as Determined by Different Arrangements of Social Consequences: Diffusion of Responsibility Effects With Competition

Abstract

According to a recently proposed synthesis, social loafing, social facilitation, and deindividuation can be viewed as different ways of arranging social consequences (B. Guerin, 1999). The effects of such arrangements have been measured in past research as productive output (social loafing and social facilitation) or as antinormative behaviors (deindividuation), but all 3 effects are manipulable by changing individual identifiability, evaluation, social identity, task difficulty, and presence in a group. The synthesis also predicted that these same variables would apply to other measures and other arrangements of social consequences. To this end, in the present 2 experiments, the author varied the arrangements for consequence diffusion in a competition situation by varying small and large competing groups and measured productive output and antinormative behaviors simultaneously. The 2 experiments showed social-consequence effects in competition situations with college students, giving further support for the social-consequence synthesis and the idea that the verbal naming of phenomena in social psychology is arbitrary.     

Age differences in women’s tendency to gossip are mediated by their mate value

In the current study it was investigated whether age differences in women’s tendency to gossip exist, and whether these could be accounted for by self-reported mate value. It was expected that younger women would report a higher tendency to gossip after reading a scenario in which a romantic rival was introduced, because they are at an age when competition for mates is salient and often intense. Moreover, it was hypothesized that this higher tendency to gossip would be attributable to these women’s higher mate value, since younger women have a higher reproductive capacity than older women. The results confirm these expectations: age differences in women’s tendency to gossip disappeared when controlling for mate value. Discussion focuses on the interpretation and implications of these results.     

Individual differences in women's perceptions of other women's dominance

Recent research on men's dominance perception suggests that the extent to which men perceive masculine men to be more dominant than relatively feminine men is negatively correlated with measures of their own dominance. In the current studies, we investigated the relationship between indices of women's own dominance and their perceptions of other women's facial dominance. Women's own height and scores on a dominance questionnaire were negatively correlated with the extent to which they perceived masculine women to be more dominant than relatively feminine women. In follow‐up studies, we observed similar individual differences when (i) women separately judged other women's social and physical dominance, suggesting that individual differences in women's dominance perceptions generalize across two different types of dominance judgment and (ii) we assessed the perceivers' dominance indirectly by using a questionnaire that measures the extent to which women view interactions with other women in competitive terms. These findings present new evidence that the extent to which people perceive masculine individuals to be more dominant than relatively feminine individuals is negatively correlated with measures of their own dominance and suggest that competition and conflict among women may have shaped individual differences in women's dominance perception.

Examining the Response Competition Hypothesis of Age Effects in Implicit Memory

ABSTRACT

Age reductions in priming have been explained by differences in processing demands across implicit memory tests. According to one hypothesis, older adults show reduced priming relative to younger adults on implicit tests that require production of a response because these tests typically allow for response competition. In contrast, older adults do not show reductions in priming on identification tests that contain little response competition. The following experiments tested the specific role of response competition in mediating age effects in implicit memory. In Experiment 1, younger and older adults studied a list of words and were then given an implicit test of word stem completion. They studied a second list of words and were given an implicit test of general knowledge. Each implicit test contained items with unique solutions (the low response competition condition) and items with multiple solutions (the high response competition condition). In Experiment 2, younger and older adults were given explicit versions of the word stem completion and the general knowledge tests. Results showed an effect of age on explicit memory (Experiment 2), but no effect of age or response competition on priming (Experiment 1). Results are inconsistent with the theory that response competition leads to age effects on production tests of implicit memory.     

Blinded by fear? Prior exposure to fearful faces enhances attentional processing of task-irrelevant stimuli

Threatening information has been shown to both capture attention and enhance sensory processing. Recent evidence has also suggested that exposure to fearful stimuli may enhance perceptual processing of subsequently presented information, as well as increase attentional capacity. However, these results are inconsistent with other findings that fearful stimuli reduce task-irrelevant distraction and improve selective attention. Here, we investigated the effect of prior exposure to fearful faces on performance in the Eriksen flanker task. Across experiments, fearful cues led to increased task-irrelevant distraction for items positioned across visual space, in contrast to other emotional expressions and inverted face items, and under conditions of attentional load. Findings support the view that fearful images enhance attentional capacity, allowing one to attend to as much visual information as possible when danger is implied. Conflicting findings on the effect of fear and selective attention are discussed.     

The role of item similarity in part-list cueing impairment

The presentation of a subset of studied items as retrieval cues can have detrimental effects on recall of the remaining (target) items. In three experiments we examined whether such part-list cueing impairment depends on the similarity between cue and target items. Item similarity was manipulated by making use of pre-experimental semantic similarities between cue and target items (Experiments 1 and 2), or was episodically induced through a similarity-encoding task, in which participants were asked to interrelate cue and target items in a meaningful way (Experiment 3). In all three experiments reliable part-list cueing impairment arose when the similarity between cues and targets was low, but no impairment was found when the similarity between cues and targets was high. Inhibitory as well as non-inhibitory explanations of the findings are discussed.     

Verbal and Nonverbal Interactions of Four- and Five-Year-Old Friends in Potential Conflict Situations

Dyads of 4- and 5-year-old friends and nonfriends attending preschools in central Italy were identified by friendship nominations. The 217 dyads of friends and non-friends participated in 2 closed-field tasks designed to simulate real-life situations of potential conflict. In the 4-year-old cohort, there were no significant differences in the behavior of the partners in either of the situations. However, at age 5 years, friends respected the rules of a fast-paced competitive game significantly more than did nonfriends. In discussing how to share a single object (a chocolate egg with a toy inside), 5-year-old friends were more likely to reach agreement than were nonfriends. The results suggest important developmental changes in the processes of negotiation and sharing within the preschool years.     

Women’s sexual competition and the Dark Triad

The Dark Triad (DT) of sub-clinical narcissism, Machiavellianism, and psychopathy has been found to be related to competitive attitudes and behaviors, chiefly in men. Using a women-only sample (n = 439), we examined the relationship of DT with general and sexual competitiveness. Factor analysis indicated that the distinction between inter- and intra-sexual competition in women may be less clear than previously conceptualized. We found significant positive correlations between DT and both general and sexual competitiveness. Regression analyses indicated that DT, and in particular, narcissism, are significant predictors of general and sexual competitiveness. These findings are discussed in relation to evolutionary theory, and directions for future work on sexual competition and DT are suggested.
