Motion perception and aging.

The authors used a correlated motion paradigm to investigate the effects of aging and gender on motion sensitivity. In 2 experiments with a total of 50 elderly and 50 young subjects, motion thresholds were significantly higher for elderly women. The correlated motion signal, which was embedded in random motion, may have been coherent to subjects in much the same way a form is in Witkin's Embedded Figures Test (EFT). In Experiment 2, EFT scores were obtained. A significant positive relationship between motion thresholds and EFT performance was found within each age group. Although gender-related perceptual style differences may contribute to motion perception effects, the authors argue that a common neural factor contributes to performance on both the EFT and the correlated motion task.     

Beliefs about condoms and accessibility of condom intentions in Hispanic and African American youth

The construct accessibility model (CAM) holds that constructs are most likely to influence behavior when they are accessible in memory. While the theory of reasoned action sees intention as an important determinant of behavior, the CAM predicts that the intention to act upon a given health behavior is not likely to be acted upon unless the intention is in an accessible state. Therefore, people who frequently talk about or think about using condoms are likely to have condom related constructs available and use them when needed. This paper reports findings from the pilot phase of a project to identify beliefs which influence condom use in Hispanic and African-American youth living in Detroit. 15 male and 15 female Hispanics and 17 male and 17 female African-Americans aged 15-21 years of mean and median age 18.5, were interviewed face-to-face in 1989 with the goal of identifying condom beliefs which may influence their condom use. 80-82% of male participants, 53% of Hispanic females, and 100% of Black females had experienced sexual intercourse, with age at first intercourse ranging between 13.1 and 16.5 years. 88% of Black women and 7% of Hispanic women were pregnant at the interview. Regarding participants' level of preventive knowledge, all but 1 recently immigrated Hispanic female knew HIV was transmitted by needles and sexual intercourse. 87% of Hispanics and 94% of African-Americans responded that condoms protect against AIDS, but only 13% of Hispanics and 47% of African-Americans knew that nonlatex condoms do not. Some participants expressed concern that condoms reduce sensitivity and/or break during intercourse. Controlling for sexual activity, 25% of Hispanic females, 83% of Hispanic males, 71% of African-American females, and 80% of African-American males had ever used a condom; no Hispanic and 14% of Blacks reported using them consistently in the 12 month period preceding the interview. With 100% of African-American males and 97% of Black females reporting thinking about using condoms compared to 80% of Hispanics, the study findings suggest that condom intentions are more accessible in African-Americans than among Hispanics.     

The construction of the self: An evolutionary view

Contemporary research on the construction of the self emphasizes the products rather than the process of self-development. Borrowing from the writings of William James and contemporary views of natural selection, we propose a model ofevolutionary self-construction. Grounded in the principles of evolution and the philosophy of pragmatism, evolutionary self-construction proposes a process that guides the seeking of “truth” inpossible selves. According to this view, the self develops in response to uncertainty reduction with the “correct” self identified via the “sentiment of rationality.” Selves presently identified as correct are considered to be “instruments of action” that facilitate the interaction between an individual and the environment. Selected selves can then be developed to one’s best advantage and presented in an optimal fashion. This model helps organize contemporary frameworks around a common theme and embraces affect as a central component in the development of the self. A previous version of this paper was presented at the 98th annual meeting of the American Psychological Association, Boston, MA.     

The Counseling Process as Defined by Relationship Types: A Test of Helms's Interactional Model

Helms (1984) presented a model to explain the influence of Black and White racial identity development on counseling interactions. The purpose of this study was to examine her hypothesis that specific combinations of racial identity attitudes contribute to qualitatively different counseling process and outcome or relationship types.     

Beyond cognitive ability: Improving the prediction of performance

New measures of practical intelligence and personality traits were assessed for their ability to improve the prediction of performance beyond cognitive ability. Measures of practical intelligence from the newly developed Constructive Thinking Inventory and traits measuring emotional stability and expedience were used as independent variables in regression analyses predicting academic performance, training performance and leadership ratings of 86 student leaders. The constructive thinking scales added significantly to the prediction of academic performance, beyond measures of cognitive ability. Constructive thinking also accounted for unique variance predicting training performance and leadership ratings. Personality traits were unrelated to performance or leadership.     

The Logic of the Development of Feminism; or,Is MacKinnon to Feminism as Parmenides Is to Greek Philosophy?

Catharine MacKinnon's investigation of the role of sexuality in the subordination of women is a logical culmination of radical feminist thought. If this is correct, the position of her work relative to radical feminism is analogous to the place Parmenides's work occupied in ancient Greek philosophy. Critics of MacKinnon's work have missed their target completely and must engage her work in a different way if feminist theory is to progress past its current stalemated malaise.     

Differential validity by sex in employment settings

The current study meta-analyzes 59 male-female pairs of validity coefficients obtained during revalidation of the General Aptitude Test Battery (GATB) for evidence of differential validity by sex. Results suggest that general cognitive ability may be slightly more predictive of rated job performance for women than for men in our sample of studies. Moderator analyses examined the effects of occupational sex-dominance and cognitive complexity. Results of these analyses indicate that, in single sex-dominated occupations, tests of general cognitive ability and perceptual ability are more valid for members of the dominant sex, and these differences are more apparent at low-complexity levels. Explanations for the findings are offered in terms of properties of the ratings criterion.An earlier version of this paper was given at the 2nd annual convention of the Society for Industrial and Organizational Psychology, Inc., Atlanta, GA. The authors thank Dave Synk for providing the occupation codes for each study.     

Suggestiveness in photospread line-ups: Similarity induces distinctiveness

The present research examined whether line-ups based on target (‘suspect’) face similarity are biased or suggestive. Four experiments are described in which subjects constructed photographic line-ups by selecting foils similar in appearance to a target. Later, another group of subjects who had not seen the faces before (mock witnesses) were asked to pick out the targets from the line-ups. All four experiments showed that mock witnesses selected the target significantly more often than expected by chance, thereby demonstrating suggestiveness. Three alternative line-up construction methods were also evaluated. In these methods, foil selection was based not only on target similarity but also on similarity with one or more of the other line-up faces. Results showed that alternative line-up targets were not selected significantly more often than chance, suggesting that bias was reduced. An overall analysis showed that the alternative line-ups were significantly less suggestive than target-based line-ups. The results indicate that foil selection procedures that incorporate foil-to-foil similarity produce fairer line-ups than those exclusively based on target similarity.
