An automated bisection device for assessing attentional neglect in clinical populations

An automated bisection device (ABD) is described that is designed for use in assessing the direction of three-dimensional neglect in various clinical populations. This device features an apparatus containing two base sections and a connecting rod, on which is located a bisection indicator assemblage that can be moved either by hand or by a calibrated motor-drive system. The indicator assemblage is, in turn, connected to a motor-control box with variable speed settings and a digital readout. The ABD can be used to measure bisection estimations along all three linear axes (lateral, vertical, and depth) by providing visual cues alone, tactile cues alone, or a combination of visual and tactile cues.     

Young adults' perceptions of social sex roles across the life span

Fifty male and 50 female undergraduates rated 10 age-sex targets (Boy, Girl, Adolescent Boy, Adolescent Girl, Young Man, Young Woman, Middle-aged Man, Middle-Aged Woman, Old Man and Old Woman) on 12 semantic differential scales. Compared with female targets, male targets were rated higher on potency and activity scales and lower on evaluative scales. Semantic distance between male and female targets showed a curvilinear relationship with target age. Results suggested that young adult subjects perceive that sex-role differences first increase and then decrease across the life span.An earlier version of this article was presented at the convention of the Western Psychological Association in Los Angeles, California, April 1976.     

Prediction as a means of inducing tolerance

Female subjects were exposed individually to the attitude item responses of a similar or dissimilar stranger. They were asked either to copy down the stranger's attitudes or to predict (with accurate feedback) how the stranger answered each item. Predict subjects were found to be more tolerant of the dissimilar stranger than were Copy subjects, while both groups were equally attracted to the similar stranger. It was suggested that training people to anticipate disagreements may be a useful way of fostering tolerance.     

Electrophysiological and behavioral indicants of selective attention to multifeature gratings

The mechanisms underlying selective attention to gratings consisting of a particular conjunction of spatial frequency and orientation were investigated by means of both visual evoked potential (VEP) and behavioral measures. The effects of selective attention upon the VEP indicated two general types of selection processes: one which is specific to the features contained in the relevant gratings and is most pronounced approximately 225 msec post-stimulation, and another which is specific to the conjunction of features defining the relevant grating and is most pronounced 250–375 msec following the presentation of the stimulus. The behavioral responses primarily reflected this latter, or grating-specific, attentional process. The results are discussed in terms of the role of sensory feature channels in mediating selective attention to visual stimuli and are related to various information processing models of visual pattern selection.     

Same-sex imitation of and reported agreement with parents and unfamiliar adults

Children aged 7, 10, and 14 were shown sets of photographs of human figures for each of which they made judgments of age or attractiveness. Randomly determined responses appeared under each set of photographs. Half the children were told the responses represented choices of parents and the other half that they represented choices of unfamiliar adults. After the opportunity to imitate, children were asked whom they thought they agreed with the most. Findings indicated only a small, borderline-significant effect for same-sex imitation, but a large, highly significant effect for reported agreement, particularly in the unfamiliar adult condition (p < .001). Discussion centered on two issues: (1) Same-sex effects appear strongest when the act of choosing between adults and the adults' gender are accentuated; and (2) differences between present and previous findings regarding same-sex effects for parents vs unfamiliar adults may relate to the ages of the children investigated.
