Sports participation and fair play

This study examined whether the participation in intermediate contact sports affects the opinions about the behaviors and attitudes of fair play in the sports context and whether these effects are influenced by ego orientation. The participants were high level sportsmen from university and professional basketball and football players (N = 131). They filled in questionnaires to assess their participation in sports, their goal orientations, and their fair play attitudes and behaviors. The analyses of the structural equation model indicated that participation in intermediate contact sports predicted ego orientation; these analyses consecutively predicted low levels of fair play. The direct effects of sports participation in fair play decreased significantly in the presence of ego orientation, indicating that the last construct partially mediates the relation between the first two variables. These discoveries help us to better understand the processes that operate in contact sports. Finally, their implications for eliminating unsportsmanlike behaviors are discussed.     

The impact of training on interpersonal influence

Contemporary research on interpersonal influence has shown that individuals scoring high in Need for Cognition (NC) are able to generate a large number of arguments in order to convince other people. However, research has also shown that such an effort does not necessarily lead them to be more persuasive or more efficient in their group performance. The present research analysed this state of affairs, replicating and extending previous research by showing that appropriate training in socio-emotional group dimensions can increase group performance for individuals high in NC. Potential underlying mechanisms for such an effect are discussed.     

Assessment of school violence and its personal effect on a sample of European students

The purpose of the present study was to analyze the prevalence of various problems of living together and school violence in a sample of 1629 pupils of Spain, Austria, France, and Hungary. The personal effect of these problems was also analyzed. The results obtained indicate a high prevalence of various school harassment behaviors (such as insults, fights, lack of rules for living together, etc.) in Austria, France, and Spain, being significantly lower in Hungary. As far as the personal effect, along with abusive behaviors among students, the students consider lack of motivation and troubled relations with teaching staff to be very significant.     

Perceptions of self-concept and self-presentation by procrastinators: further evidence

Two samples of university students completed self-report measures of chronic procrastination and either self-concept variables (Sample 1, n = 233) or self-presentational styles (Sample 2, n = 210). Results indicated that procrastination was significantly related to a self-concept of oneself as dominated by issues related to task performance, and to self-presentation strategies that reflected a person as continually justifying and excusing task delays and being "needy" of others' approval. It seems that men and women procrastinate in order to improve their social standing by making their accomplishments seem greater than they really are.     

The relationship between cognitive dissonance and helping behavior

An experiment was conducted to study the relationship between cognitive dissonance and helping behavior. A counterattitudinal procedure was employed to arouse dissonance. For half of the participants, an experimental confederate entered the room and elicited an opportunity for them to offer help. In this situation, fewer subjects in the dissonance condition offered help than subjects in the no‐dissonance condition. The least helping occurred among dissonance subjects with the highest level of commitment to the counterattitudinal task. Those with a medium level of commitment offered significantly more help. Despite the fact that results in line with Festinger's cognitive dissonance theory (subjects' attitudinal change) were obtained in the no‐helping situation, in helping situations, dissonance subjects who offered help presented significantly less attitude change than those who did not offer it. This was considered to be a result of helpfulness reducing dissonance arousal.     

Relationship between inner dialog and ideas of reference and the mediating role of dissociation

Recent lines of research have begun to concentrate on internal dialogue and its relationship to a diversity of psychopathological phenomena present in psychotic disorders. This study was intended as a preliminary exploration of the relationship of internal dialogue, dissociation and ideas of reference. To do this, a sample of 318 students filled in an internal dialogue scale (the VISQ, McCarthy‐Jones & Fernyhough), one for dissociation (DES‐II, Carlson & Putnam) and another for ideas of reference (REF, Lenzenweger, Bennett & Lilenfeld). The results confirm the hypothesis posed in the sense that internal dialogue was positively associated with dissociation and with ideas of reference. A partial mediation effect of dissociation was also found between inner speech and ideas of reference. Lines of future research this study opens and its possible integration in a model on ideas of reference are discussed.     

Analysis of distractor difficulty in multiple-choice items

Two psychometric models are presented for evaluating the difficulty of the distractors in multiple-choice items. They are based on the criterion of rising distractor selection ratios, which facilitates interpretation of the subject and item parameters. Statistical inferential tools are developed in a Bayesian framework: modal a posteriori estimation by application of an EM algorithm and model evaluation by monitoring posterior predictive replications of the data matrix. An educational example with real data is included to exemplify the application of the models and compare them with the nominal categories model.This research was supported by the DGI grant BSO2002-01485.I would like to thank Eric Maris and Vicente Ponsoda for their advice, Juan Botella for providing the data for the empirical application, and three anonymous reviewers for their comments that were essential for improving the quality of the paper.     

Eine Welt ohne Individuelle EntitÄten?

A world without individual entities? An advice to not to extract immediate ontological consequences from quantum theory. Should we assume a world without individual entities? I pledge not to extract immediate ontological consequences from quantum theory. My intention is to focus on the complexity of ontological concepts commonly associated with quantum theory. Using as an example the compatibility of EPR correlations with the existence of individual entities, it is shown that an absolute rejection of an ontological category, based on some aspects of the formalism of quantum theory, does not seem reasonable. A consequence of this argument is that the common sense view – the world is composed of individual entities – can be maintained, despite of the particularities of quantum mechanics.     

Appropriateness of the Multi-Attitude Suicide Tendency Scale for non-White individuals

Analyses of data collected from 480 university students (approximately 56% White and 44% Black) challenge the utility of the Multi-Attitude Suicide Tendency Scale (MAST) for use with individuals of diverse cultural backgrounds. This size sample allowed for an examination of the psychometric properties and cultural relevance of the MAST for non-Whites. Correlations between scores on the MAST, suicide, and depression measures were in the expected directions for Whites but not for Blacks or Latinos. The White sample data fit the four-factor model of the MAST, but the model required several modifications to fit the data from the Black sample. Verification of the cultural relevance of the MAST and a revision of the scale are recommended to improve its usefulness.     

Emotional perseveration: an update on prefrontal-amygdala interactions in fear extinction

Fear extinction refers to the ability to adapt as situations change by learning to suppress a previously learned fear. This process involves a gradual reduction in the capacity of a fear-conditioned stimulus to elicit fear by presenting the conditioned stimulus repeatedly on its own. Fear extinction is context-dependent and is generally considered to involve the establishment of inhibitory control of the prefrontal cortex over amygdala-based fear processes. In this paper, we review research progress on the neural basis of fear extinction with a focus on the role of the amygdala and the prefrontal cortex. We evaluate two competing hypotheses for how the medial prefrontal cortex inhibits amygdala output. In addition, we present new findings showing that lesions of the basal amygdala do not affect fear extinction. Based on this result, we propose an updated model for integrating hippocampal-based contextual information with prefrontal-amygdala circuitry.
