MacLab: A Macintosh system for psychology labs

MacLab, a program that turns the Apple Macintosh into a psychology laboratory tool, is described. MacLab combines intelligent editors, a millisecond timer, MacPaint pictures, and the ease of use of the Macintosh user interface to create a system with which experimental psychologists can quickly create and run powerful experiments with no need of any knowledge of programming.     

Intimacy Motivation and Subjective Mental Health in a Nationwide Sample

Over 1,200 adults in a representative nationwide sample were administered the Thematic Apperception Test (TAT) and an unstructured interview which produced 25 measures of subjective mental health and ultimately six factor scores: unhappiness, lack of gratification, strain, feelings of vulnerability, lack of self-confidence, and uncertainty. The TATs were scored for intimacy motivation (McAdams, 1980)--a recurrent preference or readiness for experiences of warm, close, and communicative interaction with others. Controlling for age, education, and their interaction, high intimacy motivation in women was associated with greater happiness and gratification, whereas in men it was associated with lack of strain and lack of uncertainty. Women high in intimacy motivation who were living alone reported lower levels of gratification and more uncertainty in their lives than other women. Intimacy motivation also declined significantly over the life span for women, but not for men. Finally, demographic effects on intimacy motivation were examined. Controlling for age, education, and their interaction, professional men (e.g., doctors, lawyers, and teachers) scored higher on intimacy motivation than did men in other occupational categories, while among women the occupational groups with highest intimacy motivation were service workers and craftspersons.     

Workplace justice outcomes as a function of adversaries' gender composition: A field assessment

There is extensive documentation that the sex of organizational members may bias a wide variety of managerial decisions and workplace outcomes. While such effects have been persuasively demonstrated, the sex context of these effects has received little attention. It is argued here that it is not merely the sex of the actor, but the nature of the dyadic match (male/male; female/female; male/female; female/male) that is a critical influence on outcomes. This hypothesis is strongly supported by gross differences in workplace justice outcomes based on the dyadic composition of the actors involved in dispute proceedings (n=369) in a field setting. These results are tempered, however, inasmuch as analysis also indicates differences in the severity of disputed issues across these dyadic compositions.

Extraversion-introversion and heat-stress tolerance

Ten Ss were tested under heat-stress conditions, during which their physiological stress was measured. Before commencement of the experiment, the Ss' level of extraversion was measured, as well as the meaning they assigned to the situation and the subjective probability of success they gave themselves. It was found that extraverts assigned significantly more positive meaning to the heat-stress situation than introverts, and they tended to estimate their probability of success as higher than did the introverts. However, extraverts tended to suffer from higher physiological stress than introverts, where the main cause for that seemed to be their higher expectations resulting from the positive meaning assigned by them to the heat-stress situation.     

Stabilized images: The search for pattern elements

In a series of four experiments, the fragmentation of stabilized lines and angles viewed in different orientations was studied. With high inter-O agreement, it was possible to demonstrate reliable differences among patterns, with resistance to fading being a function of both pattern and orientation. The results were discussed in terms of possible supraretinal stages of pattern analysis.     

Bilateral spatial summation of cooling of symmetrical sites

The possibility of spatial summation of conducted ??Ts (temperature decrements from the adapted skin temperature) was tested when the ??Ts were presented simultaneously and individually at symmetrical sites on either side of the body. The use of a signal detection rating method yielded data that indicate that spatial summation is complete (area and intensity trade reciprocally) for ??s near threshold and at clearly suprathreshold intensities of stimulation is invariant of the adapted skin temperature (AT), and the intensity of stimulation within the range of stimuli used (from as little as ?0.05?C to as much as ?1.25?C). In view of the characteristics ascribed to the thermosensory apparatus in humans, it is postulated that spatial summation occurs in the central nervous system.     

Factors affecting the acquisition and elimination of children's donating behavior

Thirty-five 6- to 10-year-old children with initial low rates of donating to help a peer either simply received a fine for each failure to donate (n = 7) or also were informed of the contingency between the fine and failure to donate (n = 28). Explanation of the contingency was necessary to increase children's donation rates. Donations continued at high rates during a gradual, unannounced removal of the fine contingency, but decreased when children were informed that fines were no longer in effect, particularly for children who had failed to donate at least once during training and had actually been fined. Overall, addition of a distraction or an inequity procedure did not reduce donating below rate reductions due to the announced extinction procedure alone.     

Emotions and cardiac contractility as reflected in ballistocardiographic recordings

Thirty-four patients with documented ischemic heart disease were followed with nine or more ballistocardiograms recorded at different occasions during a period exceeding two years. In a doubleblind procedure the reactions to life situations were explored in relation to the average rate of maximal cardiac force development as reflected from the slope of the IJ segment of the ballistocardiogram. A similar procedure was used in the analysis of emotional reactions in relation to IJ slope during stress interviews of six other patients with ischemic heart disease. Passive behavior and feelings of being defeated corresponded to low rate of cardiac force development, whereas happiness or aggressive responses to frustrations corresponded to a high rate of cardiac force development.     

Note on the squared multiple correlation as a lower bound to communality

It is demonstrated that the squared multiple correlation of a variable with the remaining variables in a set of variables is a function of the communalities and the squared canonical correlations between the observed variables and common factors. This equation is shown to imply a strict inequality between the squared multiple correlation and communality.
