A Preliminary Investigation into Pre-Competitive Mood States of Advanced and Novice Equestrian Dressage Riders

Emotional composure is considered critical in equestrian sports. The aim of the study was to investigate pre-competitive mood states in dressage riders. Thirteen advanced and 13 novice British riders completed the Profile of Mood States Questionnaire (POMS) prior to competing. A multivariate analysis of variance (MANOVA) was performed to test for a main effect of mood states on competence levels, with subsequent investigation for significant differences of individual mood states using Bonferroni adjusted alpha levels. Levels of confusion were nearing significance between advanced and novice riders, suggesting greater processing efficacy and task-specific concentration for more advanced riders. Sport psychological interventions for equestrians should focus on lowering levels of confusion and increasing task-orientated focus in novice riders.     

Improving intergroup relations with extended and vicarious forms of indirect contact

Research in social psychology has provided impressive evidence that intergroup contact reduces prejudice. However, to the extent that strategies based on direct contact are sometimes difficult to implement, scholars have more recently focused on indirect contact. An effective form of indirect contact is extended contact. According to the extended contact hypothesis, simply knowing that ingroup members have outgroup friends (extended contact), or observing these friendships vicariously (vicarious contact), can improve intergroup relations. Since its initial formulation a large body of studies has supported the validity of the extended contact hypothesis. In reviewing the available literature on two forms of indirect contact (extended and vicarious), we outline a model that identifies their antecedents and consequences, spanning from cognitive to affective to behavioural outcomes. In addition to identifying the main moderators of indirect contact, we also distinguish two different routes, one cognitive and one affective, that underlie what processes mediate their effects. Finally, we indicate some possible avenues for future research and we consider how direct and indirect contact strategies can be used in combination to improve intergroup relations.     

Can intergroup contact improve humanity attributions?

In this paper, intergroup contact was evaluated as a strategy to favor outgroup humanization. We tested a double‐mediation model, in which contact is associated with both decreased salience of intergroup boundaries and the adoption of a common identity. These recategorizations, in turn, are related to lower levels of anxiety and higher levels of empathy, both emotions being proximal predictors of outgroup humanization. The model was tested using structural equation modeling in the context of different intergroup relations: Italians versus immigrants (Study 1); Northern Italians versus Southern Italians (Study 2). Supporting the hypotheses, group representations and emotions mediated the relationship between contact and humanity attributions. The practical implications of results are discussed.     

Americans are Barbarians or Allies? Images of Americans in the Italian Social Context

Image theory was tested in the context of Italian/American relationships. Participants were Italian students. In addition to the images of ally, barbarian, imperialist, enemy, a new image was suggested: that of father. We predicted that political orientation would affect the structural perceptions (goal compatibility, relative power, relative status), and, as a consequence, the image of Americans: right-wing participants should prefer the images of father and ally, while left-wing participants should associate Americans with barbarian. Findings generally supported our predictions; also the figure of father obtained some support. The theoretical and practical implications of results are discussed.     

Faster forgetting contributes to impaired spatial memory in the PDAPP mouse: Deficit in memory retrieval associated with increased sensitivity to interference?

Two experiments were conducted to investigate the possibility of faster forgetting by PDAPP mice (a well-established model of Alzheimer's disease as reported by Games and colleagues in an earlier paper). Experiment 1, using mice aged 13-16 mo, confirmed the presence of a deficit in a spatial reference memory task in the water maze by hemizygous PDAPP mice relative to littermate controls. However, after overtraining to a criterion of equivalent navigational performance, a series of memory retention tests revealed faster forgetting in the PDAPP group. Very limited retraining was sufficient to reinstate good memory in both groups, indicating that their faster forgetting may be due to retrieval failure rather than trace decay. In Experiment 2, 6-mo-old PDAPP and controls were required to learn each of a series of spatial locations to criterion with their memory assessed 10 min after learning each location. No memory deficit was apparent in the PDAPP mice initially, but a deficit built up through the series of locations suggestive of increased sensitivity to interference. Faster forgetting and increased interference may each reflect a difficulty in accessing memory traces. This interpretation of one aspect of the cognitive deficit in human mutant APP mice has parallels to deficits observed in patients with Alzheimer's disease, further supporting the validity of transgenic models of the disease.     

Dialectical Behavior Therapy of Anorexia and Bulimia Nervosa Among Adolescents: A Case Series

The aim of this study was to describe a case series of adolescents (mean age = 16.5 years, SD = 1.0) with anorexia nervosa (AN) and bulimia nervosa (BN) who received dialectical behavior therapy (DBT). Twelve outpatients with AN and BN took part in 25 weeks of twice weekly therapy consisting of individual therapy and a skills training group. Family members were involved in the treatment. The patients were compared pre- and posttreatment on behavioral symptoms of AN and BN and symptoms of general psychopathology using standardized instruments (Structured Inventory for Anorectic and Bulimic Syndromes, Eating Disorder Inventory-2, The Symptom Checklist-90-Revised). Posttreatment, significant improvements in behavioral symptoms of eating disorder and symptoms of psychopathology were identified. The application of DBT adapted for the treatment of AN and BN among adolescents was associated with a decrease in behavioral symptoms of eating disorders and symptoms of general psychopathology. However, randomized controlled studies are required to prove the efficacy of this approach.     

Reactions to gay men: Contact and overcorrection in an employee selection simulation

The current study examines the role of contact on reactions to gay and heterosexual targets by U.S. heterosexual college students. Aversive bias research finds that minority group members receive unfavorable evaluations only when non-category-based information justifies bias. We argue that under other conditions, namely absence of conditions justifying bias, minority group members receive more favorable evaluations than non-minorities, an effect we term overcorrection. We apply this research to the study of attitudes toward gay men. The current study examines this effect on evaluations of a highly qualified male job candidate who is either gay or heterosexual and flawed or not flawed. We predicted and found, among 180 college students, that the overcorrection effect was present only for those individuals who have experienced no friendships with gay men. Those individuals who do have gay male friends did not exhibit overcorrection. We interpret this result as an indication that individuals who have gay friends (contact) ignore category information such as gay/ heterosexual and are more likely to exhibit truly egalitarian ratings. Implications for aversive bias and outgroup covariation perspectives are discussed. We presented portions of this paper at the 2000 Western Psychological Association conference, Maui, HI.     

Scientific Communication and Stereotype Change1

The aim of this experiment is to examine whether communicating the results of social psychological research improves out‐group stereotypes and diminishes in‐group bias. The experimental material consisted of 2 communications: one described Hamilton and Gifford's (1976) experiment on illusory correlation (Experiment 1); the other described Sherif's (1966) studies on summer camps. The results of the present experiment show that knowledge of Sherif's findings had no effect on evaluations, whereas an awareness of the experiment on illusory correlation produced a boomerang effect, accentuating, rather than diminishing, in‐group bias. A second experiment revealed that the persuasive power of a scientific message on stereotypes depends on whether in‐groups and out‐groups are cogni‐tively present in the message acquisition phase.
