Posturally related variations in the hand preferences of the ruffed lemur (Varecia variegata variegata)

The hand preferences of 5 semi-free-ranging black-and-white ruffed lemurs were assessed by using three distinct testing procedures. Testing conditions varied in the extent to which they required animals to make a whole body postural adjustment prior to making a reach. Minimal bodily adjustment was necessary for free foraging, whereas discrete food presentations on land (DFP-land) and in a moat (DFP-moat) promoted a gross reorientation of the animal's entire body. In the DFP-moat condition 4 animals exhibited exclusive use of the left hand, and only 1 of 515 reaches was made with the right hand. Similarly, all 5 animals showed a pronounced left hand preference in the DFP-land condition. The free-foraging condition revealed a hand preference for only 1 of the 5 subjects, and that preference was weak in comparison with those measured in the other two test conditions. These findings indicate that whole body postural adjustments critically influenced the expression of hand preference and should be taken into consideration in future studies of primate hand preferences.     

Masculine gender-role stress: predictor of anger, anxiety, and health-risk behaviors

We suggest that male gender-role identification affects whether specific situations are appraised as stressful. A questionnaire was developed to measure masculine gender-role stress (MGRS). Correlational data and multiple regression were used to validate the MGRS scale as a measure of gender-related stress in men, and compare its predictive utility with Spence's commonly-used measure of masculinity. Findings indicate that stress appraisal is gender related, that is, men experience more masculine-role stress than women. Further, the construct of MGRS was distinguished from the concept of masculinity. Finally, MGRS predicted increased anger, increased anxiety, and poorer health behaviors.     

Remembrance of sounds past: memory and psychophysical scaling

What is the role of long-term memories of previous stimulus-response mappings, and of previous sensory and perceptual experiences generally, in psychophysical scaling judgments? I conducted four experiments in an attempt to provide some preliminary answers to this question. In each experiment, subjects made judgments of the loudness of sounds on 3 successive days. Stimulus intensities were drawn randomly from the same set on Days 1 and 3 but from a different set, either all 12 dB higher or all 12 dB lower, on Day 2. Four different types of psychophysical scaling judgments were studied: category judgment without an experimenter-induced identification function, ratio magnitude estimation with a variable standard, absolute magnitude estimation, and cross-modality matching. The first two methods required completely relative judgment, the last two completely absolute judgment. Data from all methods reveal profound effects of stimulus-response mappings experienced on previous days (long-term memory) and immediately previous stimuli and responses (short-term memory) on responses to current stimuli. Responses were typically a compromise between absolute and relative judgment. Individual differences were dramatic.     

A PSYCHOLOGICAL NEEDS ANALYSIS OF MALE AND FEMALE SEX TRAIT STEREOTYPES IN MALAYSIA

As part of a cross-cultural project, 100 Malaysian university students completed Gough and Heilbrun's (1965) Adjective Check List to assess existing stereotypes of males and females. After the construction of 100 item stereotypes for males and females the data were analyzed in terms of Murray's (1938) personality theory of psychological needs. Analysis revealed that the male “personality” reflected high needs in autonomy, aggression and exhibition, but low needs for deference and nurturance. By contrast, female needs were strong in succorance and abasement but weak in dominance. These results were contrasted with those of 21 other countries and findings discussed in terms of Malaysia's multi-racial composition and influence of traditional customs and religious beliefs.     

Mixed-modality psychophysical scaling: Sequential dependencies and other properties

J. C. Stevens and Marks’s (1980) method of magnitude matching and a derivative, category matching, are examined in two experiments. Category matching produces highly similar matching functions to those of magnitude matching. The two methods are both subject to significant sequential dependencies, which, however, should not affect exponents of matching functions. Such mixed-modality scaling methods are also useful for theory testing. In the present case, responses were assimilated to the immediately previous response (different modality stimulus) but contrasted with the stimulus (same modality) two trials back in the sequence. The dependency of the response-response dependency on Sn-S_n-k was independent of stimulus modality. However, the usual dependency of the coefficient of variation of ratios of successive responses on Sn-S_n-k was not found. These results support the class of theories in which assimilative response-response dependencies and contrastive response-stimulus dependencies arise from different mechanisms, and disconfirm those in which both effects arise in a linked fashion from a single mechanism.     

The great commandment: Some implications for emotional health

Pastoral Psychology -     

The counseling assignment problem

A disposition index, DI, which provides information about each possible placement to be considered in a personnel classification situation is discussed. The index is readily computed by machine methods and can be used by counselors required to make assignments. The use of the disposition index provides an adequate approximation to optimal solutions obtained by other methods.This report is based on work done under ARDC Project No. 7702, Task No. 17051, in support of the research and development program of the Air Force Personnel and Training Research Center, Lackland Air Force Base, Texas.
