The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes. 相似文献

The Rev. is a BASIC computer program for IBM-PC-compatible systems that provides Bayesian estimates of “true” scores from multiple scores measuring the same construct. Psychological reports often include test scores from earlier evaluations without objectively incorporating them into current findings. Using Thorndike’s formulas for objectively combining test scores while providing estimates with reduced standard errors, the Rev. is an interactive program that facilitates test interpretation by combining information from many test administrations. The user provides four easily obtainable pieces of information for each test administration. The output includes an estimated “true” score and the standard error of the estimate. 相似文献

Prepared by the Working Group on Governance and Administration from the November 1995 Georgetown conference sponsored by the Association of Medical School Psychologists, this paper delineates the various trends in health care that may impact upon organizational structures for psychologists within academic medical centers. Ten variables that describe various functional issues within academic medical centers or health science centers are defined. Finally, seven organizational guidelines and recommendations pertaining to governance of psychological services are detailed. 相似文献

This pilot study was conducted to identify factors responsible for promoting resilience in siblings of children with sickle cell disease. Twenty siblings (10–17 years of age) of children (5–13 years) with sickle cell disease were selected from the Pediatric Clinic of Howard University Center for Sickle Cell Disease. The siblings responded to questionnaires, and the data obtained was analyzed by chi-square for association. The results indicated that age, birth order, and gender had no effect on resilience in the siblings. However, family size, number of parents in the home, sibling's knowledge of the illness, degree of morbidity of the illness, socioeconomic status of the family, and parents' attitudes and childrearing practices were all found to affect resilience. These findings provide additional insight into the psychosocial aspects of, and genetic counseling for sickle cell disease, as well as for other chronic genetic disorders. 相似文献

Throughout the evolution of psychoanalysis, its theories and methods have been deeply influenced by ideas about psychoanalytic neutrality. However, considerable dissension has surrounded the concept of neutrality. This paper defines five distinct categories of neutrality the author considers relevant to all theoretical perspectives on psychoanalysis: behavioral, attitudinal, interpersonal, interactional, and essential. 相似文献

Some university students who stutter report that they avoid participating in class discussions and talking with professors because they believe that if their professors find out they stutter, the professors are likely to view the students as being less intelligent and/or competent than they otherwise would. The purpose of this study was to determine whether professors, as a group, are likely to report such beliefs. A random sample of 87 professors at Marquette University, Indiana University of Pennsylvania, and the State University of New York at Stonybrook rated “A Student Who Stutters” on each of 81 seven-point, bipolar semantic differential scales, including intelligent/unintelligent and competent/incompetent. Although there was considerable scatter in their ratings for the majority of the scales, 85 of the 87 rated the student at the center or “positive” end of the intelligent/unintelligent scale and 83 of the 87 did so on the competent/incompetent one. Assuming that the attitutes reported by the professors reflect their “real” ones, these data suggest that many—perhaps the majority—do not have negative attitudes about the intelligence and competence of their students who stutter. 相似文献
