The role of strategies in deciding advantageously in ambiguous and risky situations

In decision situations of everyday life, the potential positive or negative consequences of a decision are often specified and the associated probabilities are known or they are principally calculable ("decisions under risk"). On the basis of correlations reported in patient studies, it has been recently proposed that decisions under risk involve strategic components, i.e. calculation of the risk, as well as emotional processes, i.e. processing feedback from previous decisions. However, the potential impact of calculative strategies on decision-making under risk has not been investigated systematically, so far. In the current study, we examined 42 healthy subjects (21 females) with the Game of Dice Task measuring decisions under risk, and a questionnaire assessing strategy application in items comparable to the choices in the Game of Dice Task. In addition, the subjects performed the Iowa Gambling Task, examining decision-making under ambiguity, and a neuropsychological test battery focusing on executive functions. Results indicate that deciding advantageously in a decision-making task with explicit and stable rules is linked to applying calculative strategies. In contrast, individuals who decide intuitively prefer risky or disadvantageous choices in the Game of Dice Task. Applying calculative strategies was correlated with executive functions but not with performance on the Iowa Gambling Task. The results support the view that calculative processes and strategies may improve decision-making under explicit risk conditions.     

A longitudinal twin study of the genetic and environmental etiology of maternal hostile-reactive behavior during infancy and toddlerhood

Children's negative characteristics are thought to be a factor in evoking hostile parenting responses. This can result in genotype/environment correlations (rGE) in which children's heritable traits influence the parenting they experience. We did genetic analyses on 292 mothers' self-reported hostile-reactive behaviors toward each of their twins at 5, 18 and 30 months. Finding heritability for a parenting behavior analyzed as a child phenotype is evidence of rGE correlation. The heritability of maternal behavior was modest (29% at 5 months, 0% at 18 months, and 25% at 30 months) and longitudinal analyses indicated that genetic factors at 5 and 30 months were uncorrelated. Common environment factors, probably reflecting characteristics of the mothers, were the main source of variance at the three ages and were highly correlated through time. We concluded that children's heritable characteristics evoked maternal negative response at specific times, but were not responsible for the stability of maternal hostility from infancy to toddlerhood.     

The Effects of Images of African American Women in Hip Hop on Early Adolescents’ Attitudes Toward Physical Attractiveness and Interpersonal Relationships

This qualitative study was designed to identify African American early adolescents’ subjective meanings of African American women’s sexuality through an examination of Stephens & Phillips (2003) sexual images—the Diva, Gold Digger, Freak, Dyke, Gangster Bitch, Sister Savior, Earth Mother, and Baby Mama. These eight sexual images both inform and reflect beliefs about African American women’s physical attractiveness. Interpersonal relationship decision making processes also were influenced by these conceptual frameworks of African American women’s sexuality. Findings from this study are important given the tendency of previous researchers to ignore race and intraethnic variations in studies of beliefs about attitudes toward sexuality.     

Latent state–trait theory: An application in sport psychology

ObjectiveQuestionnaires are often applied in sports psychology to measure a person's trait or state. However, the extent to which the questionnaire captures differences because of trait or state influences is often unclear. The latent state–trait (LST) theory offers the opportunity to separate both variance sources. This separation allows estimating specific reliability coefficients.DesignThe present paper gives a theoretical introduction to LST and its basic ideas. Using a real data set with N = 156 athletes we exemplify the steps necessary to derive the LST coefficients. All athletes filled out a comprehensive inventory assessing competitive anxiety on two occasions.MethodThe data are analysed with structural equation models based on LST principles.ResultsThe results confirm the questionnaire's trait saturation.ConclusionFinally, results are discussed in light of practical and theoretical implications.     

MINDS: Toward a computerized test battery for use in health psychological and neuropsychological assessment

MINDS (Mental Information Processing and Neuropsychological Diagnostic System) was developed with the goal of integrating a number of independent and stand-alone test programs that are used in the diagnosis of psychological and neuropsychological health. The system runs under MS-DOS. The shell program integrates subject information with data obtained through the use of the individual test programs. The current test battery comprises tasks on memory, attention, and motor performance; these tasks require the use of additional peripheral response devices, which are controlled via a multiple I/O interface card. Questionnaires are also included; they have been developed with the author language shell program MicroCAT. MINDS is programmed to allow easy integration of new tests. As an example, the Motor Planning Test is described. The equivalence of the computerized questionnaires with existing tests is also discussed.     

Do Obese Women Have Poorer Social Relationships Than Nonobese Women? Reports by Self,Friends, and Coworkers

Both theory and research suggest that obese women may have relatively poor social relationships even if their self-reports about their relationships do not differ from the reports of nonobese women. Seventy-seven obese and 78 nonobese women completed self-report measures of social anxiety, social self-esteem, social competence, social network size, and perceived social support from friends and family. Friends and coworkers also rated these women on the same measures. The self-reports of obese and nonobese women did not differ significantly on any of these social measures, and ratings from friends and coworkers of obese women were not different from ratings of nonobese women by friends and coworkers. These results suggest that obese women may be able to overcome prejudice against obese people in their relationships with others.     

Leadership styles and Deming's behavior factors

Although total quality management scholars, including W. Edwards Deming, consider leadership to be important, there has been little work which considers linkages between specific leadership styles and TQM behaviors/policies. This paper examines the relationship between a full range of leadership styles (Bass & Avolio, 1994) including laissez-faire, management-by-exceptionpassive, management-by-exception-active, transactional and transformational leadership, and five specific TQM behavior factors derived from Deming's (1986) Fourteen Points, i.e., change agency, teamwork, trust-building, short-term goal eradication and continuous improvement.The authors gratefully acknowledge the helpful suggestions of Boas Shamir, Don Spangler, Bruce Avolio, Francis Yammarino, and Susan Kang to earlier versions of this paper.
