Increasing Women's Calcium Intake: The Role of Health Beliefs,Intentions, and Health Value1

Undergraduate women who varied in how much they valued health were exposed to written communications persuading them of their vulnerability to osteoporosis and of the effectiveness of a recommended action in preventing this disease. Vulnerability had a significant main effect on intentions and subsequent behavior. This effect was obtained regardless of how much the subjects valued their health or whether the coping response was effective. Intentions to perform the recommended behaviors proved to be the best predictors of self-reported and actual behavior change, in support of the Ajzen-Fishbein (1980) model. Intentions, in turn, were predicted from recipients' beliefs regarding their ability to perform the behavior, their vulnerability to the health threat, and the effectiveness of the recommended threat-reducing response. Implications of these findings for health promotion campaigns are discussed.     

A longitudinal study of the moderating role of extraversion: leader-member exchange, performance, and turnover during new executive development

Identifying factors that help or hinder new executives in "getting up to speed" quickly and remaining with an organization is vital to maximizing the effectiveness of executive development. The current study extends past research by examining extraversion as a moderator of relationships between leader-member exchange (LMX) and performance, turnover intentions, and actual turnover for an executive sample. The sample consisted of 116 new executives who were surveyed prior to starting their employment and at 3 months postentry. A total of 67 senior executives rated these new executives in terms of overall performance at 6 months postentry. Turnover data were gathered from company records 3 1/2 years later. Hierarchical regression results showed that LMX was not related to performance or turnover intentions for those high in extraversion; but for individuals low in extraversion, there was a relation between LMX, performance, and turnover intentions. Furthermore, survival analyses showed that LMX was only related to turnover-hazard rate for individuals low in extraversion.     

Interpersonal mistreatment in the workplace: the interface and impact of general incivility and sexual harassment

This article examined the relationships and outcomes of behaviors falling at the interface of general and sexual forms of interpersonal mistreatment in the workplace. Data were collected with surveys of two different female populations (Ns = 833 and 1,425) working within a large public-sector organization. Findings revealed that general incivility and sexual harassment were related constructs, with gender harassment bridging the two. Moreover, these behaviors tended to co-occur in organizations, and employee well-being declined with the addition of each type of mistreatment to the workplace experience. This behavior type (or behavior combination) effect remained significant even after controlling for behavior frequency. The findings are interpreted from perspectives on sexual aggression, social power, and multiple victimization.     

Cumulating retrieval inhibition in semantic and lexical domains

In 3 experiments the authors examined changes in successive exemplar generation percentages within categories defined semantically (e.g., fruit-P, fruit-A, fruit-M) and by 1st letter (e.g., insect-C, sport-C, car-C), with a mixed control condition (e.g., fruit-P, insect-C, disease-M). Retrieval success declined across 12 successive items in both semantic and letter categories, with no change for the mixed condition. This retrieval inhibition is unrelated to taxonomic frequency of exemplars within either letter or semantic categorical structures. Furthermore, semantic retrieval inhibition appears to be long lasting, suggested by the decline in retrieval percentage across successive 12-item blocks in both the mixed and letter conditions. The authors suggest that different mechanisms underlie the inhibition found in the semantic (suppression) and letter (interference) conditions.     

Cognition at risk: Gestalt/feature-intensive processing,attention deficit,and substance abuse

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive, styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive processing theory of cognition.     

Experimental evaluation of a modular approach to mobilizing antitobacco influences of peers and parents

The experimental evaluation of two components of a community intervention to prevent adolescent tobacco use are described. Youth antitobacco activities (e.g., peer quizzes, sidewalk art, poster and T-shirt giveaways, etc.) and family communications activities (pamphlets to parents and student quizzes of parents) were evaluated in two time-series experiments, each of which was conducted in two experimental and one control community. Students in Grades 6 and 8 and their parents were assessed in a series of four phone surveys in the first experiment and six phone surveys in the second. Implementation of the youth antitobacco and family communications activities led to significantly greater exposure of young people to antitobacco information. They led to increases in parent and youth knowledge about tobacco use and more negative attitudes toward tobacco. In Experiment 2, youths in intervention communities had significantly lower rated intentions to smoke. The findings suggest the value of a modular approach to community interventions for influencing the social context relevant to the onset of adolescent tobacco use.     

Confirming universal generalizations

The purpose of this paper is to make a simple observation regarding the Johnson-Carnap continuum of inductive methods (see Johnson 1932, carnap 1952). From the outset, a common criticism of this continuum was its failure to permit the confirmation of universal generalizations: that is, if an event has unfailingly occurred in the past, the failure of the continuum to give some weight to the possibility that the event will continue to occur without fail in the future. The Johnson-Carnap continuum is the mathematical consequence of an axiom termed Johnson's sufficientness postulate, the thesis of this paper is that, properly viewed, the failure of the Johnson-Carnap continuum to confirm universal generalizations is not a deep fact, but rather an immediate consequence of the sufficientness postulate; and that if this postulate is modified in the minimal manner necessary to eliminate such an entailment, then the result is a new continuum that differs from the old one in precisely one respect: it enjoys the desideratum of confirming universal generalizations.     

Perspectives on the home advantage: A comparison of football players, fans and referees

Objectives

The study aimed to address the paucity of research pertaining to perceptions of causes of the home advantage. The views of three key personnel groups in football (soccer) were examined with regard to their perspectives.

Design and procedure

Players (n = 94), fans (n = 116) and referees (n = 163) completed a ten-item questionnaire on which they rated the contribution of the most prominent factors known to influence the home advantage.

Results

Factor analysis revealed three subscales (officials, player state and home environment) relating to explanations for the home advantage. A MANOVA examining the groups’ ratings for these three subscales found that the fans and player gave higher ratings for the contribution of officials and player state than did referees, while the fans gave higher ratings for the home environment.

Conclusion

The present study provides an insight into conceptualisations of the home advantage from the perspectives of different football groups. The relevance of self-enhancement, emanating from motivational and information processing mechanisms, is considered.     

Conceptualizing Sex Offender Denial From a Multifaceted Framework: Investigating the Psychometric Qualities of a New Instrument

The authors examined the psychometric properties of a clinician‐rated measure of sex offender denial. Convergent and discriminant validity for the measure was supported, and given its relationship to treatment attitudes, the measure demonstrated utility for assessing treatment change and readiness.     

Using ambiguous plaid stimuli to investigate the influence of immediate prior experience on perception

In a series of three experiments, we used an ambiguous plaid motion stimulus to explore the behavioral and electrophysiological effects of prior stimulus exposures and perceptual states on current awareness. The results showed that prior exposure to a stimulus biased toward one percept led to subsequent suppression of that percept. In contrast, in the absence of stimulus bias, prior perceptual experience can have a facilitative influence. The suppressive effects caused by the prior stimulus were found to transfer to an ambiguous plaid test stimulus rotated 180º relative to the adaptation stimulus, but were abolished if (1) the ambiguous test stimulus was only rotated 90º relative to the adaptation stimulus or (2) the adaptation stimulus was heavily biased toward the component grating percept. Event-related potential recordings were consistent with the involvement of visual cortical areas and suggested that the influence of recent stimulus exposure may involve recruitment of additional brain processes beyond those responsible for initial stimulus encoding. In contrast, the effects of prior and current perceptual experience appeared to depend on similar brain processes. Although the data presented here focus on vision, the work is discussed within the context of data from a parallel series of experiments in audition.
