Emotional distress and the perceived interference of menstruation

The relation of perceived interference of menstruation on expected behaviors to emotional distress was examined. It was predicted that the perceived interference of menstruation would be more predictive of emotional distress associated with menstruation than either menstrual or premenstrual pain. Participants completed measures of menstrual pain and visual analogue scales of emotional distress (anger, frustration, depression, anxiety, fear). Measures of perceived ability to tolerate the pain, the perceived interference of the pain, and attitudes toward menstruation were also collected. Results indicated that perceived interference was the strongest predictor of emotional distress secondary to menstrual pain. Ratings of menstrual and premenstrual pain were also significant predictors of emotional distress. Results supported the major hypothesis of the study and provide evidence that the appraisal of interference imposed by a particular condition or Stressor may be an important factor in stress and coping processes.     

Programming experiments on a TERAK 8510/A microcomputer

In the course of bringing up one’s first experimental microcomputer system, certain standard problems occur that are trivial to the experienced programmer but are great blocks to the novice. In this spirit, some paradigms that were implemented on a TERAK 8510/a microcomputer, and the related problems, are described. Specific topics include some consideration of timing procedures for reaction time experiments and how to handle large text files on small floppy disk systems.     

A stereotaxic positioning platform for double-angle placements

A simple and inexpensive device for double-angled positioning of electrode carriers during stereotaxic surgery is described. The device consists of a base and adjustable vertical point that is used to locate the position of final stereotaxic coordinates in space. This allows reproducible placements for deep midline brain structures that require double-angle approaches. Such placements are easily obtained with this instrument on standard and even single-carrier stereotaxic instruments.     

Discrepancy and nondiscrepancy methods of assessing visual-auditory interaction

Much of our information about interaction among the sensory modalities has come from studies in which discrepancy between the modalities has been imposed experimentally. The question arises whether the conclusions generated from discrepancy research are affected by the use of the nonnatural experimental situation: Would the same conclusions be reached if discrepancy were not used? In addition to using the index of interaction derived from discrepancy, as in prior research, the present study assessed two nonexperimentally imposed indices to explore the interaction between vision and audition in a spatial localization task. The additional indices, or “tags,” were standard deviations (SDs) and confidence ratings (CRs) of localization responses. The SD tag showed a pattern of interaction between vision and audition that was identical to that found with spatial discrepancy. The CR tag produced a similar pattern but did not show the same regular variation with the independent variable. Both SD and CR tags showed identical patterns of results when an experimentally imposed discrepancy was and was not used, suggesting that the use of moderate degrees of experimental discrepancy does not produce misleading conclusions about intersensory interaction.     

The role of visual-auditory “compellingness” in the ventriloquism effect: Implications for transitivity among the spatial senses

A magnitude estimation response procedure was used to evaluate the strength of visualauditory intersensory bias effects under conditions of spatial discrepancy. Maj or variables were the cognitive compellingness of the stimulus situation and instructions as to the unity or duality of the perceptual event. With a highly compelling stimulus situation and single-event instructions, subjects showed a very high visual bias of audition, a significant auditory bias of vision, and a sum of bias effects that indicated that their perception was fully consonant with the assumption of a single perceptual event. This finding reopens the possibility that the spatial modalities function as a transitive system, an outcome that Pick, Warren, and Hay (1969) had expected but did not obtain. Furthermore, the results support the model for intersensory interaction proposed by Welch and Warren (1980) with respect to the susceptibility of intersensory bias effects to several independent variables. Finally, a new means of assessing intersensory bias effects by the use of spatial separation threshold was demonstrated.     

Belief and Subjective Well-Being in Outpatients

Background. The purpose of this study was twofold: to test the hypothesis that religious and spiritual beliefs provide medical outpatients with a system of meaning and existential understanding, and to seek to determine some elements that constitute the domain of spiritual and religious beliefs as they relate to subjective well-being. Methods. The Spiritual Well-Being Scale (SWBS) questionnaire was administered to a convenience sample of adult outpatients. Results. Patients agreed, strongly to moderately, with statements that had a direct reference to God having a significant influence (cares about me, concerned about my problems, contributes to my sense of well-being) on the daily life of the respondent. Conclusion. Religious and spiritual beliefs provide medical outpatients with a system of meaning and existential understanding. Outpatients identified with more cognitive rather than affective perceptions of well-being, in addition to a conceptualization of what a loving God may mean.     

A Cross-Cultural Study of Response Biases in Personality Measures

The purposes of this study were to (a) compare the response bias tendencies of U.S. and Philippine college students and men and women in each culture when responding to personality measures, (b) examine the comparability of different measures of the same response biases, (c) examine the stability or consistency of response biases across instruments, (d) examine the extent to which controlling for response biases affects cultural mean comparisons in personality variables, and (e) test hypothesized personality correlates of response biases. The results did not support the presence of large cross-cultural or gender differences in response biases. Moderate to high agreement was found between different indexes of the same biases. Participants' response bias tendencies were moderately stable across instruments. Controlling for response biases led to trivial changes in effect sizes; in most cases, conclusions about cultural differences in personality constructs did not change. Most hypotheses relating personality variables to response biases were not supported.
