Sex typing and the coronary-prone behavior pattern

The purpose of this study was to examine the relationship between sex-role orientation and the coronary-prone behavior pattern [Type A]. Ninety-six males and eighty-four females were administered the Bem Sex Role Inventory and the student version of the Jenkins Activity Survey. The results showed that, irrespective of sex, Type A subjects were significantly more instrumental (masculine) and less expressive (feminine) than Type B subjects. Consistent with previous research females were found to be more expressive than males; however, the sole predictor of instrumentality was A/B classification. The potential significance of these findings for refining predictions of coronary artery and heart disease is discussed and recommendations for future research are offered.Portions of this paper were presented at the Third Annual Meeting of the Society of Behavioral Medicine, Chicago, March 1982.     

Andisp: A Turbo pascal program to analyze and display sampled data

ANDISP is a Turbo Pascal program that analyzes, displays, and manipulates sampled data recorded with a PC-compatible data-acquisition system The data analysis routines include “integrate/differentiate a channel”, “rectify,” “smooth,” “filter,” and “add/sub/mult/div a channel by a constant, ” as well as a routine that gives some basic statistics. The data manipulation routines are “copy a channel” or “copy the data buffer to a file.” The versatile display routine can give either oscilloscope-type displays of a data channel or plots of pubUshable quality. Hardware requirements are an IBM-compatible microcomputer and an EGA color monitor.     

Motion aftereffects and retinal motion

Two experiments are described in which it was investigated whether the adaptation on which motion aftereffects (MAEs) are based is a response to retinal image motion alone or to the motion signal derived from the process which combines the image motion signal with information about eye movement (corollary discharge). In both experiments observers either fixated a stationary point or tracked a vertically moving point while a pattern (in experiment 1, a grating; in experiment 2, a random-dot pattern) drifted horizontally across the field. In the tracking condition the adapting retinal motion was oblique. In the fixation condition it was horizontal. In every case in both conditions the MAE was horizontal, in the direction opposite to that of pattern motion. These results are consistent with the hypothesis that the adaptation is a response to the motion signal derived from the comparison of eye and image motion rather than to retinal motion per se. An alternative explanation is discussed.
