Spatial compatibility of signal-response position in pointing

Two experiments are reported in which, by means of a pointing task, we studied the stimulus-position effect, i.e. the inverted U-shape form of the reaction-time function in relation to stimulus position in tasks in which stimuli and/or responses are arranged in a horizontal array. The response consisted of aiming the index finger from a central starting point at a target area on a screen. Reaction time was the main dependent variable. The spatial relation between the position of the imperative signal and the position of the response was manipulated by varying the spatial S-R compatibility and physical distance that separated the positions of stimulus and response. The stimulus-position effect was shown to depend on the compatibility of the S-R relation (Exp. 1). In Exp. 2 it was found that the modulation of the stimulus-position effect by spatial compatibility disappeared completely when the distance between the positions of stimulus and response was reduced. None of the experiments revealed that the stimulus position effect depended on signal discriminability, which renders an interpretation of this effect in terms of perceptual processes unlikely. We argue that the attentional model of spatial coding provides the most reasonable explanation of the obtained reaction-time patterns.     

MFT trainee adjustment to program lifestyle stress: The TAPS scale

The 30-item Trainee Adjustment to Program Stress (TAPS) scale was developed to measure lifestyle stress of family therapy trainees. Initially, 70 items were generated from propositional statements based on four constructs. Following pilot testing, 329 out of 900 (37%) student members of the American Association for Mariage and Family Therapy (AAMFT) returned TAPS questionnaires. Internal consistency reliability analyses and principal components and factor analyses produced a final 30 item TAPS scale appropriate for use in family therapy training programs. Reliability and validity measures are reported.     

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.     

Cocaine—review of current literature and interface with the law

Cocaine use in the United States has currently reached epidemic proportions. This has resulted in syndromes of intoxication, overdose, and withdrawal, meeting all DMS-III criteria for a substance that can cause dependence as well as abuse syndromes. This paper reviews the current epidemiology of cocaine, its history and pharmacology with major focus on clinical syndromes. This is followed by a review of the current knowledge of the relationship between cocaine and violence and the forensic-psychiatric issues surrounding cocaine.     

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.     

Long-term predictive validity of the WPPSI: An 11-year follow-up study

As part of a longitudinal study, a control group of 85 children were tested on the WPPSI at 5$\text{1}\text{2}$ years and the WISC-R at 16$\text{1}\text{2}$ years. Educational attainment was also assessed in adolescence. Data are presented illustrating the long-term predictive validity of the WPPSI. The Full Scale IQs on the two tests intercorrelated +0.86.
