Asymmetries and errors in perception of depth from disparity suggest a multicomponent model of disparity processing

In three experiments, asymmetries between the processing of crossed and uncrossed disparities were investigated. The target was a luminance-defined circle concentric to a fixation mark, viewed stereoscopically on a computer monitor for 105 msec. Fifteen disparities were presented according to the method of constant stimuli. Observers indicated the apparent direction of target depth relative to fixation. All experiments measured both the accuracy and latency of this response. Experiment 1 showed fewer errors and shorter reaction times for identifying crossed disparities. Experiments 2 and 3 replicated Experiment 1 and also showed that observers may often perceive a target in the direction opposite that prescribed by the disparity information. We propose that the asymmetries and reversals result from differences in computation of sign, not of magnitude. This notion is consistent with a scheme of continuous disparity tuning and accounts for such asymmetries and errors without positing disparity pooling mechanisms.     

Personality and charismatic experience among adult christians

A sample of 368 committed Christian adults completed the Index of Charismatic Experience together with the short form Revised Eysenck Personality Questionnaire and the Myers Briggs Type Indicator (MBTI). The data demonstrate that, according to the MBTI typology, Christians who prefer “thinking” are likely to score higher on the Index of Charismatic Experience than Christians who prefer “feeling”. According to the Eysenckian dimensional model of personality, the charismatic experience is associated with stable extraversion.     

Unimanual Performance as a Measure of Laterality

The study of unimanual performance as a measure of laterality has ranged from simple concepts such as tests of handedness to highly complex conceptualizations interrelating anthropologic, cultural, genetic, and neurological aspects, including difference between unimanual performance in brain injured versus normal samples. This paper traces measures of unimanual performance through behavioral correlates of natural and unnatural sinistrality as related to cerebral organization, and concludes that unimanual performance represents a robust phenomenon with implications for understanding of neuropsychological correlates of behavior.     

Codependency: An interpersonal phenomenon

An alternative perspective to the clinical model of codependency is that codependency is contextual and reflects inequality within a relationship. This study examined whether the evaluation of codependent behavior depends on the context of the relationship, i.e., the reciprocity of the person’s partner, and the gender of the stimulus person (SP). College students (N=302, 46% non-Caucasian) read one of six scenarios in which the codependent SP’s behavior was held constant but the reciprocity of the partner and the gender of the SP were varied. The stimulus person and her/his relationship were rated significantly more healthy in the reciprocal condition than in the nonreciprocal or control conditions, but a better partner in the nonreciprocal condition. Codependent female SPs were judged less healthy but better partners than codependent male SPs. Judgments of codependent behavior and persons are contextual in nature, may reflect inequality within relationships, and to some extent, depend upon the gender of the codependent person.     

The Balance of Power in Romantic Heterosexual Couples Over Time from “His” and “Her” Perspectives

In this investigation, the balance of power between men and women in romantic relationships was examined with a sample of 101 heterosexual couples, some of whom were surveyed up to jive times over a four-year period. A majority of the participants (who were primarily Caucasian and middle class) reported some imbalance in power in their relationship (53% of the men and 52% of the women on a global measure of power; 67% of the men and 65% of the women on a measure of decision making). The longitudinal data indicated that perceptions of power were quite stable over time. When power imbalances in relationships occurred, the male partner was more likely than the female to be seen as the power holder, although these differences were statistically significant only for men (full sample). In support of W. Waller's principle of least interest [(1937) The Family: A Dynamic Interpretation, New York: Gordon], being the less emotionally involved partner in the relationship was associated with greater power. We further found that men were more likely than women to perceive themselves as the less emotionally invested partner. Perceptions of power balance were generally unrelated to either relationship satisfaction or to the likelihood that the couple broke up over time. In one exception, men who perceived their relationship to be equal in power (but not decision making) reported the highest level of satisfaction. We conclude that the balance of power still often favors men in these romantic couples (especially in decision making), although couples do not always agree on their perceptions, with male partners tending to see more male dominance than females.     

Burnout in Spurned Medical Caregivers and the Impact of Job Expectancy Training

This study represents an extrapolation to the practical realm of a theoretical model that has been supported thus far only by laboratory studies. The model regards the rejection of help by people in need as being stressful for caregivers partly because it violates their expectations of acceptance and threatens their self-image as competent caregivers. It was hypothesized that high levels of perceived rejection by patients and others at work would contribute to burnout in medical caregivers. It was also predicted that high levels of stress preparation in caregivers' training with regard to job expectancies and patient (non)compliance would lessen burnout and buffer the effects of spurning. Responses to a questionnaire by a sample of physicians and hospital nurses revealed a direct association of perceived spurning, as well as an inverse association of stress preparation with burnout, and gave some indication of buffering, as hypothesized. Expressions of violated expectancies and of job disillusionment were directly associated with burnout and inversely associated with stress preparation. Informal job expectancy shaped by coworkers was found to be directly associated with burnout in physicians, but it was inversely associated with burn out in nurses. The implications of these findings are considered     

A NOTE ON TRANSFER OF STIMULUS CONTROL IN THE DELAYED-CUE PROCEDURE: FACILITATION BY AN OVERT DIFFERENTIAL RESPONSE

This case study describes initially unsuccessful attempts to use the delayed-cue procedure to teach conditional discriminations to an individual with moderate mental retardation. The task was matching printed-word comparison stimuli to dictated-name sample stimuli. In three experiments, the subject typically waited for the delayed cue unless differential responses to the dictated samples (repeating the sample names) were required. Hence, the study provides an example of a way to make the delayed-cue method more effective. The stimulus control bases for the results are discussed.     

An evaluation of differential prediction of WIAT achievement scores from WISC-III FSIQ across ethnic and gender groups

This study examines differential prediction of WIAT achievement scores based on WISC-III FSIQ in white as compared with African American and Hispanic children, and in females as compared with males. A procedure which allows simultaneous comparisons of slopes and intercepts across groups is employed. The results are consistent with previous research findings in supporting the general absence of bias in predicting achievement from IQ.     

College Students' Attitudes Toward Abortion: The Role of Knowledge and Demographic Variables1

The present study sought to determine the role that knowledge of abortion information and various demographic variables play in discriminating between those who approve and those who disapprove of abortion. Four hundred and fifty-four college students completed the Abortion Knowledge Test, constructed by the researchers, as well as an abortion attitudes questionnaire which asked subjects to indicate their degree of approval or disapproval of abortion in the case of 7 different scenarios. Attitudes toward abortion were significantly predicted by knowledge of abortion-related information above and beyond the significant influence of degree of religiosity, religion, and age. No significant gender differences were found. Respondents who indicated approval of abortion scored significantly higher on the Abortion Knowledge Test and tended to be older, less religious, and non-Catholic compared to those who disapproved of abortion.
