Inhibitory avoidance deficit following short-term adrenalectomy in the rat: the role of adrenal catecholamines 总被引:4,自引:0,他引:4
Impaired retention of an inhibitory avoidance response was observed in rats subjected to adrenalectomy (ADX) up to 120 hr before the single learning trial. Corticosterone substitution failed to normalize this behavioral deficit. Rats ADX 240 hr prior to the learning trial showed a normalized behavior. Adrenomedullectomy (ADXM) 48 or 240 hr before learning caused a similar impairment as in short-term ADX rats. The 240-hr ADX rats subjected to corticosterone substitution showed the same behavioral deficit as short-term ADX rats or ADXM ones. Immediate postlearning subcutaneous injection of adrenaline in a dose range of 0.005-5.0 micrograms/kg or of noradrenaline (0.005-0.5 microgram/kg) to 48-hr ADX rats resulted in a dose-related improvement of later retention behavior. Higher doses of catecholamines were less or ineffective. Postlearning treatment of 48-hr ADXM rats with adrenaline (0.5-500 micrograms/kg) caused a similar pattern of behavioral changes. It is concluded that adrenal catecholamines play an important role in the modulation of consolidation of memory. In addition, the high circulating ACTH levels that follow long-term ADX may correct for the behaviorial deficit induced by the absence of adrenomedullary catecholamines. 相似文献

A modified form of Nathanson and Becker's (1983) Health Belief Model Questionnaire and other measures designed to assess cognitive processing were administered to low-income black adolescent female clients of an inner-city comprehensive health care clinic. The purpose of the study was to explore determinants of sexual activity and contraceptive use. Subjects were classified as not sexually active (n = 50), sexually active/noncontracepting (n = 20), or sexually active/contracepting (n = 72). Not sexually active subjects tended to be younger, more career motivated, to have a father at home, to be more influenced by family values, and to have more conservative attitudes regarding adolescent sexuality than did sexually active subjects. Sexually active/noncontracepting subjects tended to report fewer benefits and more barriers to the use of contraception. Level of cognitive processing did not differ among the three groups, but was at a lower-than-expected level for age. Finally, inconsistent contraceptive use was common to both sexually active groups. 相似文献

When adolescents behave in socially unacceptable ways, overt interparental conflict is widely held to be the cause. Empirical studies, however, have been inconsistent in supporting this assumption. Some researchers therefore have speculated that covert conflict also plays a role. In the current observational study, evidence was found that both overt parental conflict and some forms of covert conflict play roles. During problem-solving family discussions, parents of adolescents whom they had brought into an outpatient clinic for treatment overtly disagreed with each other significantly more often than did parents with adolescents who did not require treatment. Families of clinic adolescents also exhibited significantly more silence during their discussions, and mothers spent significantly less time talking than did their nonclinic counterparts. The implications that both the overt and covert conflict may have for adolescent behavior are discussed. 相似文献

Psychotherapy outcome studies do not accurately represent current models of psychotherapy. A proposed remedy 总被引:3,自引:0,他引:3
J B Persons 《The American psychologist》1991,46(2):99-106
It is argued that the design of contemporary psychotherapy outcome studies is conceptually incompatible with the models of psychotherapy evaluated in those studies. Contemporary outcome studies are incompatible with psychotherapy models because the outcome studies treat patients with standardized treatments that are assigned on the basis of psychiatric diagnosis rather than with individualized treatments based on a theory-driven psychological assessment of the individual's difficulties. One possible remedy, idiographic outcome studies using a case formulation model of assessment and treatment, is proposed here. It is suggested that this research strategy may narrow the scientist-practitioner gap and make it easier to demonstrate differential outcomes of different treatments. 相似文献

This study compares social relationships of 677 mothers in families requesting shelter with those of 495 mothers in housed families, randomly selected from the public assistance caseload in New York City. As hypothesized, women seeking shelter had experienced higher levels of a variety of childhood and adult events indicative of disruptions in social relationships. Contrary to our hypothesis, they were more likely than were housed mothers to have had recent contact with parents, other relatives, and friends, although they felt less able to draw on these resources for help with their current housing needs. More than three fourths of families seeking shelter had already stayed with members of their social network in the past year. The data suggest that they had used up potential sources of support before turning to public shelter. 相似文献

Although interest in identifying effective psychotherapies for adolescent mental health problems has increased dramatically in the last decade, there have been few attempts to summarize and integrate the recent empirical literature on psychotherapy outcomes with adolescents. The present paper reviews the methods and findings of adolescent psychotherapy outcome studies published from 1978 to 1988. Evaluations of individual psychotherapy with adolescents generally reveal positive short-term outcomes, but long-term outcomes are still to be determined. Evaluations of systemic therapies (especially family therapy) with adolescents often reveal positive outcomes that are maintained over extended follow-up periods. Recommendations are presented for improving the methodology of future psychotherapy outcome studies with adolescents. 相似文献

This paper reports on in-depth interviews with black and white unmarried adolescent mothers, from a variety of socioeconomic backgrounds, about their pregnancy resolution. They revealed the importance of family members and other significant adults in the decision process. The analysis also indicated that personal, familial, and religious values were primary considerations in deciding to bear and keep their children. 相似文献

Psychometric detection of schizotypy: perceptual aberration and physical anhedonia in relatives of schizophrenics. 总被引:1,自引:0,他引:1
We administered scales of Perceptual Aberration (PERAB) and Physical Anhedonia (PHYSAN), traits that may be related to risk for schizophrenia, to 54 schizophrenics, 146 of their first-degree relatives (evaluated for schizophrenia-related disorders), and 178 normal subjects (screened for psychotic disorders in them or their relatives). For both scales, there was a significant effect of group membership. For the PERAB scale, the schizophrenics had higher scores than the normal subjects, who had higher scores than the relatives. For the PHYSAN scale, schizophrenics had higher scores than their relatives, who had higher scores than the normal subjects. Patterns of familial correlations also suggested that physical anhedonia, but not perceptual aberration, may be familial among schizophrenics and their relatives. The PHYSAN scale, but not the PERAB one, may be a useful indicator of liability for schizophrenia among the relatives of affected probands. 相似文献

This paper extends Jung's work on the relationship of art to (postulated) archetypes of the collective unconscious. Archetypes of the collective unconscious, according to Jung, are revealed to ego consciousness only by way of images--images of a specific form. Jung suggests that archetypes, primordial images, combine two aspects in a single form and are therefore paradoxical. The wise old man and youth and hermaphrodites illustrate Jung's definition of a primordial image. My study of Jung's illustrations concludes that he is referring to what I term double-figures as the design form of primordial imagery. I elaborate upon the design form of double-figures, and illustrate my conception of archetypal imagery through comparative analysis of nine cases of double-figure imagery from selected prehistoric and contemporary societies. Double-figures, as archetypal primordial imagery of the collective unconscious, are spontaneously generated, autonomous, and known to a wide variety of societies. I distinguish between form and content in the study of primordial imagery, and conclude with a summary of the importance of Jung to the cross-cultural study of art. 相似文献

The dual purposes of applied research-contributing to understanding and improvement-are only partially served by method systems that encourage studying (with increasing precision) a narrow range of questions of modest societal importance. To optimize contributions to challenging societal problems, a field's cherished standards should be adapted to support more adventuresome forms of community research and action. This paper outlines 10 values for community research and action, based on insights from the fields of behavioral and community psychology. These values-reflect the goals and challenges of establishing collaborative relationships with research participants, determining research goals and methods, designing and disseminating interventions, communicating research findings, and advocating for community change. Critical challenges are outlined, and implications for the field and its clients are discussed. 相似文献
