The role of facial attractiveness and facial masculinity/femininity in sex classification of faces

We tested whether adults (experiment 1) and 4 - 5-year-old children (experiment 2) identify the sex of highly attractive faces faster and more accurately than not very attractive faces in a reaction-time task. We also assessed whether facial masculinity/femininity facilitated identification of sex. Results showed that attractiveness facilitated adults' sex classification of both female and male faces and children's sex classification of female, but not male, faces. Moreover, attractiveness affected the speed and accuracy of sex classification independently of masculinity/femininity. High masculinity in male faces, but not high femininity in female faces, also facilitated sex classification for both adults and children. These findings provide important new data on how the facial cues of attractiveness and masculinity/femininity contribute to the task of sex classification and provide evidence for developmental differences in how adults and children use these cues. Additionally, these findings provide support for Langlois and Roggman's (1990 Psychological Science 1 115 121) averageness theory of attractiveness.     

Serial murder and the case of Aileen Wuornos: attachment theory, psychopathy, and predatory aggression

The extant research on female homicide has yet to offer any systematic assessment of why women murder serially. Part of the explanation is attributed to existing literature focusing on justifiable and excusable homicide, or women who kill their abusive partners because they have been battered, fear that their lives are in danger, or are otherwise victimized. Thus, predatory homicide perpetrated by women has not received extensive attention in the relevant literature. This article aims to address this deficiency by providing a detailed case study analysis of Aileen Wuornos, a convicted serial murderer executed at Broward Correctional Institution in Pembroke Pines, FL, on October 9, 2002. By linking the literature on attachment theory with the research on psychopathy and predatory aggression, this article argues that Aileen Wuornos was a cold blooded and calculated killer: a serial offender responsible for her delinquent and criminal behavior. Generalizing from the case of Aileen Wuornos, several tentative recommendations are proposed as linked to clinical and forensic prevention, diagnosis, and treatment, as well as future research on women, psychopathy, and predatory serial homicide.     

Calibrating the sociometer: the relational contingencies of self-esteem

A longitudinal daily diary study examined how chronic perceptions of a partner's regard for oneself might affect the day-to-day relational contingencies of self-esteem. Married partners each completed a diary for 21 days, and completed measures of satisfaction twice over the year. Multilevel analyses revealed that people who chronically felt more positively regarded compensated for one day's acute self-doubts by perceiving greater acceptance and love from their partner on subsequent days. In contrast, people who chronically felt less positively regarded by their partner internalized acute experiences of rejection, feeling worse about themselves on days after they feared their partner's disaffection. Over the year, such self-esteem sensitivity to rejection predicted declines in the partner's satisfaction.     

Frequency, probability, and prediction: easy solutions to cognitive illusions?

Many errors in probabilistic judgment have been attributed to people's inability to think in statistical terms when faced with information about a single case. Prior theoretical analyses and empirical results imply that the errors associated with case-specific reasoning may be reduced when people make frequentistic predictions about a set of cases. In studies of three previously identified cognitive biases, we find that frequency-based predictions are different from-but no better than-case-specific judgments of probability. First, in studies of the "planning fallacy, " we compare the accuracy of aggregate frequency and case-specific probability judgments in predictions of students' real-life projects. When aggregate and single-case predictions are collected from different respondents, there is little difference between the two: Both are overly optimistic and show little predictive validity. However, in within-subject comparisons, the aggregate judgments are significantly more conservative than the single-case predictions, though still optimistically biased. Results from studies of overconfidence in general knowledge and base rate neglect in categorical prediction underline a general conclusion. Frequentistic predictions made for sets of events are no more statistically sophisticated, nor more accurate, than predictions made for individual events using subjective probability.     

“Nothing About Me, Without Me”: Participatory Action Research with Self-Help/Mutual Aid Organizations for Psychiatric Consumer/Survivors

Participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors is reviewed. We begin by tracing the origins of and defining both participatory action research and self-help/mutual aid. In so doing, the degree of correspondence between the assumptions/values of participatory action research and those of self-help/mutual aid for psychiatric consumer/survivors is examined. We argue that participatory action research and self-help/mutual aid share four values in common: (a) empowerment, (b) supportive relationships, (c) social change, and (d) learning as an ongoing process. Next, selected examples of participatory action research with psychiatric consumer/survivor-controlled self-help/mutual aid organizations which illustrate these shared values are provided. We conclude with recommendations of how the key values can be promoted in both the methodological and substantive aspects of future participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors.     

INCREASED PEER-TEACHING WITH GROUP-ORIENTED CONTINGENCIES FOR ARITHMETIC PERFORMANCE IN BEHAVIOR-DISORDERED ADOLESCENTS1

Group-oriented contingencies were applied to increase the arithmetic problem-solving rates of four behavior-disordered adolescent residents in a psychiatric hospital. The experiment followed an ABAC reversal design consisting of baseline conditions (A₁ and A₂), and cumulative (B) and mixed (C) interdependent group-oriented contingency conditions. Under the cumulative arrangement, the subjects earned five cents for every correctly solved multiplication problem. The same conditions were in effect with the mixed contingency, except that each subject was required to work at least three problems before any subject could earn money. The results indicated consistent increases in the subjects' arithmetic computation rates as a function of the group-oriented contingencies. Concurrent observations were made across the four conditions of the experiment on four categories of the subjects' verbalizations: antecedent peer-teaching, consequent peer-teaching, positive statements, and negative statements. The subjects' rates of antecedent peer-teaching verbalizations covaried with the group-contingency-induced increases in their levels of computation behavior. The majority of the verbalization involved answers to number fact questions or redirecting peers to engage in on-task activities. The three other categories of the subjects' verbalizations that were observed—consequent peer-teaching, positive statements, and negative statements—were not found to covary with the subjects' altered rates of computation behavior.     

Initial internal reliability and descriptive statistics for a brief assessment tool for the Life Skills Training drug-abuse prevention program

Adolescent drug use in the United States remains the highest in the industrialized world. Fortunately there have been significant advances in developing effective prevention programs for adolescent drug use. An important issue in evaluating such programs is that the self-report surveys have adequate psychometric properties and assess constructs targeted by an intervention. A questionnaire focusing on knowledge and drug-related measures was developed to evaluate the research-based Life Skills Training drug prevention intervention. The questionnaire showed good internal reliability, detected change from pretest to posttest, and was brief and easy to complete by 45 middle-school students.     

Decision Difficulty in the Age of Consumer Empowerment

In this review, we examine the impact of two key factors of consumer empowerment–choice freedom and expansion of information--on the choice difficulty consumers experience in today’s decision environment. We posit that though these two consumer empowerment factors offer numerous potential benefits, they also can magnify such sources of decision difficulty as task complexity, tradeoff difficulty, and preference uncertainty. Next we review several key moderators, including consumer knowledge, mental representation, and maximization tendencies as well as information type and organization, that can exacerbate or mitigate the effect of these consumer empowerment factors on decision difficultly outcomes. Lastly, we examine the effectiveness of decision aids in assisting consumers navigate the complexity of today’s decision environment, and we identify areas for future investigation.
