When stereotypes hurt: Three studies of penalties for sex-role reversals

Three studies that demonstrate penalties for sex-role reversals are reported. In each study, subjects evaluated men and women who behaved either in line with sex-role stereotypes or counter to them. The results show that popularity ratings and perceived psychological adjustment of both passive-dependent men and aggressive-assertive women were adversely affected. The findings are discussed in terms of their contribution to recent theories about women's achievement motivation.     

Recognition and recall as measures of long-term retention

Acquisition and retention of a list of paired associates were measured either by cued recall or by multiple-choice recognition. The method of testing used during original learning was combined factorially with the type of test administered after a 1-week interval. Speed of learning to criterion under the two procedures was comparable. Long-term recognition was substantially higher than recall. This difference did not interact significantly with the method of learning. Recall benefited substantially from a prior test of recognition, but there was little effect when the order of tests was reversed. It is concluded that (a) both occurrence and retrieval information were stored under each condition of learning, and (b) occurrence information is less subject to forgetting than retrieval information.     

Peripheral and central components in variants of the Mueller-Lyer illusion

Illusion decrement with prolonged inspection was used as a technique to assess the relative amount of central component in seven variants of the Mueller-Lyer illusion. Results indicate that all of the variant forms share a common, central component, while the peripheral components, such as lateral inhibition, vary as a function of the presence of converging lines in the illusion configurations.     

An empirical taxonomy of visual illusions

A classification system for visual-geometric illusions, based upon the interrelationships between behavioral responses to various distortions was created. Forty-five illusion configurations were presented to 221 observers. Factor analysis revealed that there are five classes of illusions. A secondorder analysis revealed that visual distortions are ultimately reducible to two global types of distortions: illlusions of extent and illusions of shape or direction.     

Prism adaptation with simultaneous receipt of normal input

A 20-diopter vertically-displacing prism was worn on one eye in conjunction with plane glass on the other. Five groups ofSs differed in the density of a neutral filter worn over one eye. No aftereffect could be measured in either eye in any condition where the luminance of the “normal” field was equal to or greater than that of the prism field. As the luminance of the “normal” field is decreased below that of the prism field, the magnitude of aftereffect increases and is measurable in each eye.     

Should assessment center dimension ratings be mechanically-derived?

This study examined the relationship between consensusderived and mechanically-derived assessment center ratings using a sample of 110 police candidates. It was determined that the two sets of dimension ratings were highly correlated (medianr=.83). Further, the mechanically-derived and the consensus-derived assessment ratings both correlated with the overall assessment ratings (OAR) at .71. It was estimated that the organization in this study could save $6137.92 a year, and $36.89 per assessee by eliminating the team meeting (consensus decision-making).     

The Importance of Contraceptive Attributes Among College Students

This study assessed how ratings of the importance of contraceptive attributes varied with gender, age, relationship status, and contraceptive method usually used. In a classroom setting, 210 male and 217 female university students completed the 55-item Contraceptive Attribute Questionnaire (CAQ). Significant differences on importance ratings were found between women and men, age groups, women using barrier methods and women using the pill, and by relationship status. The underlying dimensions of the CAQ were investigated through factor analysis, and somewhat different factors emerged for men and women. Implications for the provision of family planning services to college students are discussed.     

Caffeine,impulsivity, and memory scanning: A comparison of two explanations for the Yerkes-Dodson Effect

Two explanations for the Yerkes-Dodson Effect (1908) were tested. Easterbrook (1959) proposed that arousal reduces the range of cue utilization. Thus, arousal should interfere with the capacity for simultaneous (dual) memory scans. In contrast, Humphreys and Revelle (1984) proposed that arousal facilitates sustained information transfer but interferes with short-term memory. Arousal should thus reduce the time needed to prepare to respond but increase the time needed to scan memory. Either caffeine or placebo was given to 78 subjects who differed in impulsivity. They completed three versions of a memory-scanning task: two single-task versions (physical and category matches) and one dual-task version (either type of match). As predicted by Humphreys and Revelle, relative to placebo, caffeine lowered the intercept (p<.01), suggesting facilitation of sustained information transfer, but increased the slope (p<.05), suggesting impairment of access to short-term memory, of the regression of reaction time on log-transformed memory-set size. That caffeine had a main effect on slopes and on intercepts but did not interact with type of task suggests that arousal does not necessarily disrupt dual-task performance.
