Mate choice decisions: the role of facial beauty

For most people, facial beauty appears to play a prominent role in choosing a mate. Evidence from research on facial attractiveness indicates that physical beauty is a sexually selected trait mediated, in part, by pubertal facial hormone markers that signal important biological information about the displayer. Such signals would be ineffective if they did not elicit appropriate cognitive and/or emotional responses in members of the opposite sex. In this article, I argue that the effectiveness of these hormonal displays varies with perceivers' brains, which have been organized by the degree of steroid hormone exposure in the uterus, and activated by varying levels of circulating steroids following puberty. I further propose that the methodology used for examining mate choice decisions has general applicability for determining how cognitive and emotional evaluations enter into decision processes.     

Intertrial sources of stimulus control and delayed matching-to-sample performance in humans

Two experiments compared delayed matching-to-sample (DMTS) accuracy under 2 procedures in adults with mental retardation. In the trial-unique procedure, every trial in a session contained different stimuli. Thus, comparison stimuli that were correct on one trial were never incorrect on other trials in that session (or vice versa). In the 2-sample DMTS procedure, the same 2 comparison stimuli were presented on each trial, and their function changed quasi-randomly across trials conditional upon the sample stimulus. Across 2 experiments, 7 of 8 subjects showed the highest overall accuracy under the trial-unique procedure, and no subject showed consistently higher accuracy under the 2-sample procedure. Negative, exponential decay functions fit to logit p values showed that this difference was due largely to the steeper delay-mediated decline in sample control for the 2-sample procedure. Stimulus-control analyses indicated that, under the 2-sample procedure, the selection of the comparison stimulus on Trial N was often controlled by the comparison stimulus selection on Trial N-1 rather than the Trial-N sample stimulus. This source of competing stimulus control is not present in trial-unique procedures. Experiment 2 manipulated intertrial interval duration. There was a small but consistent increase in accuracy as a function of intertrial interval duration under the 2-sample procedure, but not under the trial-unique procedure.     

Exact and resampling probability values for weighted kappa

Permutation procedures to compute exact and resampling probability values for weighted kappa are described. Comparisons with asymptotic probability values demonstrate that exact permutation procedures are advantageous for sparse data sets, whereas resampling permutation procedures are appropriate for both sparse and nonsparse data sets.     

Gender-Based Biases in Occupational Hiring Decisions1

Two studies which investigated gender-based decision making in an occupational setting are reported. Participants judged the suitability of a male or a female applicant with identical résumés for a male-dominated or a female-dominated position. In Study 1. where participants gave their own judgments of the suitability of the applicants for the positions, there was no evidence of gender-based biases. In Study 2. participants were required to take the perspective of the applicant in providing their judgments of suitability. In this experiment, gender-based biases were apparent, with a positive bias toward the male applicant. Results are discussed in terms of occupational stereotyping and subtle sexism.     

Distinguishing between applied research and practice

Behavior-analytic research is often viewed along a basic-applied continuum of research goals and methods. The applied portion of this continuum has evolved in ways that combine applied research and service delivery. Although these two facets of applied behavior analysis should be closely related, more clearly distinguishing between them, particularly in how we conceptualize and conduct applied research, may enhance the continuing development of each. This differentiation may improve the recruitment and training of graduate students.     

Psychological testing and pilot licensing

This article reviews contemporary trends in the psychological testing of pilots. It is written in the particular context of draft European Joint Aviation Authorities licensing proposals which, in certain circumstances, envisage psychological testing for pilot licensing purposes. The article aims to clarify issues relating to the validity, reliability, and value of pilot psychological testing in this particular context. It is first suggested that the entire domain is characterized by terminological and methodological confusion. The economic and other benefits of psychological testing are contrasted with the potential risks, including abuse and the use of tests in circumstances for which they were never designed. Reference also is made to cultural differences that potentially may impact on the practical realities of psychological testing--especially within the European context, where the debate is presently at its most intense.     

Women as cues for men's approach or distancing behavior: A study of interpersonal sexist discrimination

The purpose of this study was to investigate interpersonal sexist discrimination, operationally defined as distancing behavior. A heterogeneous sample of participants were approached at four train stations and completed two paper and pencil simulated seating measures, a sex role attitudes measure, and provided demographic information. It was predicted that in the neutral situations presented in the seating measures where there is a choice to sit either next to a man or a woman, men would more often choose to sit next to a man but women were not expected to make seating choices based on the gender of the person seated. Men's seating choices were found to be influenced by the gender of target persons whereas women's choices were not, but men either distanced from or approached women target persons. Self-reported sex role attitudes were found not to be related to distancing behavior.We gratefully acknowledge the assistance of Alyson Andrews, Nicholas Geraci, Scott Marino, Stacy Schiff, Robert Victoria, and Lisa Zamara, seniors at the University of Rhode Island, who served as investigators in this study and also assisted in the coding of data.
