A versatile two-part system for on-line measurement of multiple response parameters

A two-part system for digital measurement of such diverse response parameters as latency, pulse width, amplitude, and events per unit time is described. The mainframe consists of counters with light-emitting diode (LED) numeric readouts and a quartz crystal controlled internal time base. It also contains all power supply requirements for both the mainframe electronics and the second part of the system, the plug-ins. Each plug-in is designed to use the main unit counters, timers, readouts, and power supplies to measure the desired parameter. Thus, each numeric readout channel of the mainframe may be used to measure various parameters simply by changing the plug-in attached to it. The unit has proved to be very useful in reducing experimenter error in measuring response parameters in classical nictitating membrane conditioning.     

Sex differences in knowledge of occupational dimensions across four age levels

The purpose of the present study was to better understand the development of children's occupational knowledge, as assessed by their ability to give ratings to jobs along various dimensions that were similar to ratings given by adults, and to investigate differences in boys' and girls' ratings. Overall, younger students gave higher ratings to the jobs pictured than did older students. Also, females gave higher ratings to three of the four dimensions investigated. Girls rated traditionally female jobs higher on respect and service, while boys rated traditionally male jobs higher on respect and service. Both males and females agreed that more education would be required for the female jobs pictured, but that males would be paid more money for the male jobs pictured.     

Women in Technology: A Program to Increase Career Awareness

Most women work to help support themselves and their families. Unfortunately young women are not often encouraged to explore occupational options that offer increased economic mobility. This article describes a program designed to develop awareness of nontraditional technical careers for women, careers that require less than four years of postsecondary education. Attended by guidance counselors and math and science teachers, the conference explored the psychological implications of nontraditional choices as well as provided information about these occupations. The article also discusses funding, program development and design, and evaluation.     

“Kramer vs. Kramer” vs. Kramer: A child's rights ignored

The media continue to exercise power in transmitting values. “Kramer vs. Kramer” made film history recently by claiming an impressive number of Oscars. Written reviews and televised acclamations repeatedly cited the authentic and sympathetic treatment of the parents. However, consistent with society's present attitude toward children, the ethical and legal rights of the child were not addressed. The plot underscored the paternalistic and utilitarian manner by which we approach problem-solving and decision-making which directly involve and affect children.     

Behavioural family therapy and the influence of a systems framework

A family approach using the techniques of behaviour modification, to a family presenting with problems of encopressis in a five-year-old boy, is described. The usefulness of taking a broader analysis of the context of the behaviours targeted for modification under the impact of systems theories is emphasized. A one-year follow-up after treatment demonstrated both symptomatic and family changes.     

What's fine for the gander isn't always good for the goose: Sex differences in self-confidence as a function of ability area and comparison with others

Previous investigators have suggested that women display lower self-confidence than men across almost all achievement situations. The empirical validity of this suggestion is assessed in an experiment testing the following hypotheses: (1) Sex differences in self-confidence depend upon the particular ability area. (2) Women's self-confidence is more influenced than men's by characteristics of the particular individual with whom they compare themselves. Undergraduates completed verbal, interpersonal perceptiveness, spatial-mechanical, and creativity subtests. After each subtest, subjects estimated both their own score and that of the average undergraduate, the average male undergraduate, or the average female undergraduate. Self-confidence was operationally defined in terms of how favorably subjects compared their work to that of their peers. As predicted, women's self-confidence was lower than men's in only the spatial-mechanical and creativity subtests; and for women, but not for men, self-confidence depended upon which peer was specified. It is concluded that situation variables do determine sex differences in self-confidence and that women's self-confidence may be unduly affected by situation-specific comparison cues.The preparation of this article was supported in part by a Doctoral Dissertation Fellowship in Women's Studies awarded to the author by the Woodrow Wilson National Fellowship Foundation.

Accommodation fatigue and dark focus: The effects of accommodation-free visual work as assessed by two psychophysical methods

Past studies of accommodation fatigue have yielded inconsistent results, partly because they have not used direct measures of accommodation, and partly because they may have been based on a misleading conception of the nature of accommodation. The dual-innervation theory of accommodation suggests that the resting position of accommodation may be neuromuscular rather than just muscular, and that it lies not at optical infinity, as assumed by older conceptions, but at some intermediate position (dark focus). Among the predictions that may be deduced from this theory is that long-term visual work not requiring active accommodation will not induce fatigue. The present study involved continuous measurements of dark focus for 10 young adults over a 3-h period, using the laser optometer with two psychophysical procedures Ibracketing and staircase. Consistent with the prediction, no changes in dark focus were found, in spite of the demanding visual task. Furthermore, it was found that both psychophysical methods yielded essentially identical results. The practical and theoretical implications of these results are discussed, and recommendations are given regarding situations in which each of the psychophysical methods is likely to be most useful.     

Depth separation and the Ponzo illusion

The Ponzo illusion refers to an apparent change in length of objectively equal parallel lines induced by enclosure within an acute angle. The present study investigated this illusory change in stimulus extent as a function of the relative depth positions of the parallel lines and the inducing angle. To permit facile and unconfounded manipulation of apparent depth, the stimuli comprising the Ponzo configuration were stereoscopic contours formed from dynamic random-element stereograms. The main results were: (1) apparent depth separation exerted a strong influence on illusion magnitude; (2) this influence was asymmetrical in that illusion magnitude decreased when the inducing angle appeared in depth behind the parallel lines and increased when the inducing angle appeared in depth in front of the lines. These data are consistent with a general theory of space perception that assumes that information about depth position is processed prior to information about stimulus characteristics.
