Determinants of competitive performance expectancies of young male athletes1

Although performance expectancies have been shown to be important mediators of achievement behavior, few specific determinants of personal expectancies have been identified, the ecological validity of previous results is limited, and factors influencing group performance expectancies have not been determined. Therefore, the purpose of this field study involving 11- and 12-year-old male soccer players was twofold. First, we examined specific intrapersonal and situational factors influencing players' pregame personal and team performance expectancies. Second, we investigated the effects of winning and losing a competitive soccer game on players' postgame team expectancies involving a hypothetical rematch with the identical opponent. The pregame findings revealed that (a) the intrapersonal factors of ability and self-esteem were related to personal performance expectancies while competitive trait anxiety was not, and (b) the situational factors of past win-loss record and a prior game win or loss against the same opponent influenced team performance expectancies. The postgame findings revealed that future expectancies were affected by the interactive effects of game win-loss and self-esteem.     

Self-protection and growth as the motivational force behind majority group members' cultural adaptation and discrimination: A parallel mediation model via intergroup contact and threat

What motivates majority group members to adapt to or reject cultural diversity? Considering the relevance of personal values on our attitudes and behaviours, we inspected how self-protection and growth predict levels of discriminatory behavioural and cultural adaptation intentions towards migrants via intergroup contact and perceived intergroup threats, simultaneously (i.e., parallel mediation). Specifically, positive contact between groups is known for reducing prejudice through diminishing perceived intergroup threats. Yet current research emphasises the role of individual differences in this interplay while proposing a parallel relationship between perceived intergroup threats and contact. Also by inspecting cultural adaptation and discriminatory behavioural intentions, the present study examined more proximal indicators of real-world intergroup behaviours than explored in past research. Using data from 304 US Americans, structural equation modelling indicated a good fit for a parallel mediation model with growth relating positively to cultural adaptation intentions and negatively to discriminatory behavioural intentions through being positively associated with intergroup contact and negatively with perceived intergroup threats, simultaneously. The reverse was found for self-protection. These findings stress that personal values constitute a relevant individual difference in the contact/threats-outcome relationship, providing a motivational explanation for majority group members' experience of cultural diversity in their own country.     

Psychological characteristics of aggressive drivers with and without intermittent explosive disorder

We compared two groups of aggressive drivers, those who met criteria for Intermittent Explosive Disorder (IED) (n=10) and comparable aggressive drivers who did not meet IED criteria (n=20), to a group of non-aggressive driving controls (n=20) on measures of psychological distress, anger, hostility, and Type A behavior as well as measures of aggressive driving and driving anger and their driving records. There were few differences between the aggressive drivers with IED and those without IED. The IED positive aggressive drivers endorsed more assaultiveness and resentment as well as more impatience and showed trends to have more hostility and angry temperament. When all aggressive drivers were compared to controls, differences emerged on anxiety, hostility, and anger as well as on measure specific to aggressive driving (competitiveness) and driving anger (at slow drivers and traffic obstructions).     

Thought-shape fusion in anorexia nervosa: an experimental investigation

Cognitive biases and cognitive distortions have been implicated as important factors in the development and maintenance of many disorders. The concept of thought-shape fusion (TSF) in eating disorders was developed by Shafran, Teachman, Kerry, and Rachman (British Journal of Clinical Psychology 38 (1999) 167) as a variant of thought-action fusion, described by Shafran, Thordarson and Rachman (Journal of Anxiety Disorders 10 (1996) 379). TSF occurs when thinking about eating certain types of food increases a person's estimate of their shape and/or weight, elicits a perception of moral wrongdoing, and/or makes the person feel fat. Shafran et al. (1999) examined both the psychometric and experimental properties of TSF in an undergraduate sample. This paper reports an extension of this work to a clinical group (N=20) of patients with anorexia nervosa. After completing a set of relevant questionnaires, participants were asked to think about a food which they considered extremely fattening. They were then asked to write out the sentence, "I am eating--.", inserting the name of the fattening food in the blank. After being asked to rate their anxiety, guilt, feelings about their weight, morality, etc., participants were given the opportunity to neutralize their statement in any way they chose. The majority of the participants neutralized in ways consistent with the findings of Shafran et al. (1999). The results are discussed in terms of cognitive-behavioural formulations of eating disorders, and of the influence of cognitive biases and cognitive distortions on the processing of information relevant to food, weight and shape in anorexia nervosa.     

Affirmation of personal values buffers neuroendocrine and psychological stress responses

Stress is implicated in the development and progression of a broad array of mental and physical health disorders. Theory and research on the self suggest that self-affirming activities may buffer these adverse effects. This study experimentally investigated whether affirmations of personal values attenuate physiological and psychological stress responses. Eighty-five participants completed either a value-affirmation task or a control task prior to participating in a laboratory stress challenge. Participants who affirmed their values had significantly lower cortisol responses to stress, compared with control participants. Dispositional self-resources (e.g., trait self-esteem and optimism) moderated the relation between value affirmation and psychological stress responses, such that participants who had high self-resources and had affirmed personal values reported the least stress. These findings suggest that reflecting on personal values can keep neuroendocrine and psychological responses to stress at low levels. Implications for research on the self, stress processes, health, and interventions are discussed.     

Expectancies for Sexually Abused Children: Evidence of Perceiver Bias

We investigated perceiver bias in relation to children labeled as sexually abused. Building on recent research indicating that adults perceive children with such a label as having more behavioral problems and lower achievement, we replicated and expanded upon an earlier study. We tested undergraduate students (N = 699), who judged a six-year old child's aggressive behavior in vignettes that varied on severity of the aggressive behavior, child gender, and family history (sexually abused, mother dying of cancer, normal). Perceiver bias was related to family history label for internalizing behavior problems and competence issues and child gender for internalizing behavior problems and externalizing behavior problems. Implications for educators and practitioners are discussed as well as routes for future research.     

Dimensions of impulsivity and aggression associated with suicide attempts among bipolar patients: a preliminary study

Impulsivity and hostility are often thought to be interrelated among depressed patients with suicidal behavior, but few studies have examined this relationship empirically. In this study, we assessed trait impulsivity and hostility among 52 DSM-IV bipolar subjects with and without histories of suicide attempts. Impulsivity and hostility were correlated among attempters (r = .41, p = .03) but not non-attempters (r = .22, p = .28). As compared to non-attempters, attempters had significantly higher levels of overall hostility, more extensive subcomponents of hostility, and a trend toward higher overall impulsivity. Associations between lifetime suicide attempts and overall hostility were significant while controlling for current depression severity and lifetime illness duration. Aggression and impulsivity appear linked among bipolar patients with lifetime suicide attempts but may be independent constructs among non-attempters. The presence of both factors may elevate risk for suicidal behavior.     

A meta-analytic review of gender variations in children's language use: talkativeness, affiliative speech, and assertive speech

Three sets of meta-analyses examined gender effects on children's language use. Each set of analyses considered an aspect of speech that is considered to be gender typed: talkativeness, affiliative speech, and assertive speech. Statistically significant average effect sizes were obtained with all three language constructs. On average, girls were slightly more talkative and used more affiliative speech than did boys, whereas boys used more assertive speech than did girls. However, the average effect sizes were either negligible (talkativeness, d=0.11; assertive speech, d=0.11) or small (affiliative speech, d=0.26). Larger effect sizes were indicated for some language constructs depending on either the operational definition of the language measure, the method of recording, the child's age level, the interaction partner (adult or peer), group size, gender composition, observational setting, or type of activity. The results are interpreted in relation to social-developmental and social-constructionist approaches to gender; these views are presented as complementary--rather than competing--meta-theoretical viewpoints.     

Thought suppression in spider-fearful and nonfearful individuals

The authors examined the suppression of spider-related thoughts in spider-fearful (n = 23) and nonfearful (n = 22) individuals. Participants were primed with vivid pictures of spiders and a story about spiders. Next, they were randomly assigned to 1 of 2 conditions: (a) suppression of thoughts associated with the previously presented spider-related stimuli or (b) free expression of any thoughts, including those related to the spider-related stimuli. All participants completed a subsequent free-expression exercise. Results indicated that spider-fearful individuals expressed thoughts about the spider-related stimuli for a longer length of time than did nonfearful individuals, particularly in the suppression condition. Participants in both groups demonstrated a rebound of thoughts associated with the spider-related stimuli following suppression. The authors propose that the priming of feared stimuli makes suppression of fear-related thoughts particularly difficult for fearful individuals, perhaps by activating a state of heightened arousal.
