Abstract. This paper uses an evolutionary perspective to identify variables influencing compliance with moral codes about honest communication. Data on over one thousand radio conversations among lobster fishers in two harbors in Maine are compared in regard to the sharing of information. The sharing of accurate information is found to be significantly more frequent in the harbor that is more integrated by reciprocally altruistic relationships. This is consistent with the view that moral systems are systems of indirect reciprocity, but it also suggests that humans have evolved to base their compliance with moral codes on cues from their social environment. 相似文献

Favourite objects (FOs) of autistic children were compared with the FOs of healthy preschool and school children as well as mentally handicapped children. Three clusters of objects were obtained for normal children (comprising primary transitional objects and their forerunners, secondary transitional objects, and non-cuddly toys). When autistic children and mentally handicapped children were included, a fourth cluster of deviant objects was found. Frequency distributions of the two handicapped groups in the clusters were similar. Similarities between the two handicapped groups were also found within each cluster. The occurrence of secondary transitional objects was rare in the handicapped groups. The characteristics of "autistic" FOs reported in earlier case studies (e.g. being hard, often having an exciting effect, not being used in their adequate functions) were typical only of objects in the fourth cluster. 相似文献

A small clinical survey was undertaken at East Carolina University School of Medicine to examine the factors which influenced the decisions of five families to continue pregnancies after a chromosomal abnormality was detected. Little has been published concerning the psychosocial effects after continuing pregnancies in which the fetus was diagnosed with a chromosome abnormality by amniocentesis. In order to identify the factors that influenced their decisions, an interview with each couple was undertaken using a 25-part questionnaire. This paper addresses the method of interviewing, case material, and background concerning each couple and the summary of the results. 相似文献

We describe a principle of reinforcement that draws upon experimental analyses of both behavior and the neurosciences. Some of the implications of this principle for the interpretation of behavior are explored using computer simulations of adaptive neural networks. The simulations indicate that a single reinforcement principle, implemented in a biologically plausible neural network, is competent to produce as its cumulative product networks that can mediate a substantial number of the phenomena generated by respondent and operant contingencies. These include acquisition, extinction, reacquisition, conditioned reinforcement, and stimulus-control phenomena such as blocking and stimulus discrimination. The characteristics of the environment-behavior relations selected by the action of reinforcement on the connectivity of the network are consistent with behavior-analytic formulations: Operants are not elicited but, instead, the network permits them to be guided by the environment. Moreover, the guidance of behavior is context dependent, with the pathways activated by a stimulus determined in part by what other stimuli are acting on the network at that moment. In keeping with a selectionist approach to complexity, the cumulative effects of relatively simple reinforcement processes give promise of simulating the complex behavior of living organisms when acting upon adaptive neural networks. 相似文献

In the author's own words: I am a cancer patient involved in an agonizing struggle against disease. I decided to write about the humiliating aspects of cancer because I have experienced them firsthand. I know them all too well. I have incorporated my feelings about the humiliation of disease ... hoping they may help the reader better understand.Cynthia McGinnis Richards died of Hodgkin's Disease in February 1988. 相似文献

Near-point and far-point binocular and monocular sighting tests given 20 high and 20 low achievers each from regular classrooms at Grades 4, 8, and 12 (N = 240) yielded significant chi 2 for differences of proportions of lateral agreement with sidedness in comparison to distributions unrelated to sidedness. Composite sighting congruent to sidedness yielded significant differences between classroom and reading clinic samples. The near-point binocular sighting test markedly influences distributions of combined scores in sighting. 相似文献

As genetic testing becomes an integral part of the evaluation of deaf infants and children, it is important to understand parental views on genetic testing. The purpose of this study is to examine parental reasons for, and beliefs about, genetic testing for deafness in early-identified infants, and to determine if they differ as a function of ethnicity. We present baseline data collected from 56 Caucasian, 59 Hispanic, and 24 Asian parents of deaf children participating in a longitudinal, prospective study on genetic testing for connexin-related deafness. The overall finding is that reasons for, and beliefs about, genetic testing for deafness varied as a function of ethnicity. Virtually all parents sought genetic testing to understand why their child is deaf. However, Asian and/or Hispanic parents were more likely than Caucasian parents to view family planning, helping with their child's medical care, and helping the family as other important reasons for testing, and were more likely than Caucasian parents to perceive genetic testing to be useful for these purposes. Asian and Hispanic parents were more likely than Caucasian parents to perceive genetic testing in harmful terms. Genetic testing fulfills a cognitive need for parents to understand why their child is deaf, yet differences in responses suggest that Asian and Hispanic parents may seek testing for other purposes. Understanding different perspectives on genetic testing for deafness will enhance genetic counselors' cultural competence and facilitate the pre-test genetic counseling session. 相似文献

This is the second article of a two-part professional development series on genetic counseling for personal and family histories of psychiatric disorders. It is based on an Educational Breakout Session presented by The Psychiatric Special Interest Group of the National Society of Genetic Counselors at the 2006 Annual Education Conference. While the first article in this two part series dealt with addressing family histories of psychiatric disorders in clinical practice, the following discussion deals with the generation and provision of individualized recurrence risks for psychiatric disorders, based on empiric risk data. We present four cases that illustrate important components of and process for generating individualized risk assessment for family histories of psychiatric disorders. 相似文献

Eating disorders have a profound and highly specific impact on psychosocial functioning. The aim of this research was to develop a measure of such secondary impairment. A 16-item, self-report instrument was developed, the Clinical Impairment Assessment (CIA), which was designed to measure such impairment overall and in three specific domains (personal, cognitive, social). The psychometric properties of the instrument were evaluated using data collected in the context of a transdiagnostic treatment trial. The findings consistently supported the utility of the instrument with the CIA being shown to have high levels of internal consistency, construct and discriminant validity, test-retest reliability, and sensitivity to change. The CIA should be of value to clinicians when assessing patients with eating disorders and their response to treatment. It should also help inform epidemiological research. 相似文献
