This study sought to investigate the effects of mild head injury on a particular type of cognitive ability, verbal analogical
reasoning. The performance of 19 individuals with head injuries was compared to a group of 30 control subjects matched for
age, education, and gender on 100 verbal analogies. Solution times and error rates were modeled. Unstandardized regression
weights for individual subjects were correlated with subjects’ performance on a number of standardized ability tests. Results
showed that compared to the control subjects, the head injured subjects: (a) were significantly slower to solve the analogies,
and were particularly slow to perform certain processes: encoding/inference and comparison; (b) tended to show greater variability
in performance; and (c) had data that had a poorer componential model fit. The data suggest that analogical reasoning is affected
by a head injury, and that certain information processes may be responsible for performance deficits. 相似文献

Single letters were presented for from one to five flashes, with S required to report what he saw after each flash. The clarity of the letter increased sharply with repetition. Since the letters were no larger than one-third of a degree in size, clarity could not have been increased by S making different fixations from flash to flash and combining them into a total percept. Nor was S guessing, since this could be ruled out by other indicators. Thus, it was concluded that repetition of the stimulus can have a direct effect on the clarity of a S’s percept of that stimulus. 相似文献

Coping—competence theory yields a structural model of the development of persistent aggression in which current challenge encounters determine future life outcomes and competence. Driven by this model, universal, school-based prevention programs would aim in multiple ways to promote prosocial coping among high-risk, resilient, and advantaged youth from kindergarten through high school. Expected benefits of prosocial coping would include: less aggressive behavior, fewer adverse life outcomes (e.g., school dropout, police arrest, teen pregnancy, conduct, mood, and substance-use disorders), and a more competent self-definition and social reputation. Five stages are described that may prove useful in creating prosocial schools and neighborhoods supportive of youth in transition away from antisocial coping and deviant peers. 相似文献

Therapists are increasingly considering chemical addiction from a family systems perspective. Effects of chemical dependency upon the family are discussed and intervention approaches aimed toward assisting the family as families redefine themselves and change their structure are considered. The integration of chemical dependency treatment and the family therapy is also discussed as it is practiced in an intensive outpatient program at a psychiatric hospital. 相似文献

This review describes two clinically significant face processing deficits, prosopagnosia and Capgras delusion, and provides new knowledge about the face recognition process by a convergence of empirical findings. These empirical findings are structured around two questions that are viewed from the perspectives of the two deficits. First is the question of hemispheric specificity, which inquires into the degree of each hemisphere's contribution to the face recognition process. Second is the question of dual neural pathways, which addresses the possibility that the face recognition process proceeds along two parallel pathways in the brain. Findings from the hemispheric specificity studies reinforce the current view that right hemisphere involvement is necessary for face recognition while left hemisphere involvement is minimal. Findings from the dual neural pathways studies reinforce the plausible but yet unproven hypothesis that two neural pathways pass information from the visual association cortex in the occipital lobe toward the temporal lobes and limbic system when faces are seen and recognized. These findings, which also indicate that each of the dual neural pathways carries different, nonredundant information, could be instrumental in showing that the pathways play different roles in the manifestations of the clinically significant face processing deficits, prosopagnosia and Capgras delusion. 相似文献

Congenital bilateral absence of the vas deferens (CBAVD) occurs in approximately 1.3% of infertile males and is thought to be, in most cases, a primarily genital form of cystic fibrosis (CF). Fourteen males with CBAVD considering microsurgical sperm aspiration from the epididymis (MESA) and in vitro fertilization were seen for genetic counseling and screening for CF. To retrospectively evaluate these patients' perceptions of the counseling and screening information, we conducted structured telephone interviews to assess their recall of information about CF and its impact on their health concerns and reproductive plans. We found that, as the health implications of CF are abstract and not as important to patients as the diagnosis of CBAVD itself, patients tend to view their CF status primarily in terms of their reproductive potential. Retrospective analysis afforded us an opportunity to identify the psychosocial issues of most concern to this unique patient population. 相似文献

This research reports findings in a 10-year study of an apraxic adult, who was one of five subjects described by Shankweiler and Harris, (Cortex, ,2 277–292, 1966). Confusion matrices and feature analysis were used to compare 1965 and 1975 performances. Results indicate that over the 10-year period, errors of place, manner, and omission were markedly reduced. Voicing errors, however, while reduced in total number, still constituted a significant percentage of the patient's residual errors. Implications of these findings are discussed. 相似文献
