American psychologists are informed on Pavlov’s work on conditional reflexes but not on the full development of his theory of higher nervous activity. This article shows that Pavlov’s theory of higher nervous activity dealt with concepts that concerned contemporary psychologists. Pavlov used the conditioning of the salivary reflex for methodological purposes. Pavlov’s theory of higher nervous activity encompassed overt behavior, neural processes, and the conscious experience. The strong Darwinian element of Pavlov’s theory, with its stress on the higher organisms’ adaptation, is described. With regard to learning, Pavlov, at the end of his scholarly career, proposed that although all learning involves the formation of associations, the organism’s adaptation to the environment is established through conditioning, but the accumulation of knowledge is established by trial and error. 相似文献

The authors contend that there are logical inconsistencies in a theory put forth by Michael Green and Daniel Wikler ("Brain death and personal identity," Philosophy and Public Affairs 1980 Winter; 9(2): 105-133) to justify the brain death concept of death. Green and Wikler had asserted that individuals cease to exist and are dead when the criteria for continuity in their personal identity are not met. Having argued that the theory of personal identity is misguided, Agich and Jones suggest that further research into the ontological foundation of brain death concepts should begin, not by rejecting medical or moral considerations, but by carefully defining the main competing concepts of brain death as brain stem death, cerebral death, death of the brain as a whole, and whole brain death, and then by relating these concepts to the ontological conditions for being a live individual or person. 相似文献

This paper describes an attempt at forming and conducting a unique single-gender psychotherapy group with severely disturbed female adolescents on a long-term, psychotherapeutically oriented co-ed inpatient unit. The focus of this group was assisting the female patients in negotiating the tasks and conflicts specific to their gender and developmental stage. The therapeutic approach and the role of female coleaders are described, emphasizing particular modifications made to meet the needs of this group. Clinical examples are offered to high-light salient group themes of identity formation and separation and individuation. Finally, group therapeutic factors specifically enhanced by single gender membership are discussed and observations regarding the group/milieu interface are explored. 相似文献

This study examined the implications for social comparison theory of the proposition that women have lower self-confidence than men when there is a socially defined standard of performance. To this end, it was hypothesized that women would judge themselves to be similar to a lower ranked person, whereas men would judge themselves to be similar to a higher ranked person. Furthermore, it was hypothesized that women would choose to see a score lower than their own, whereas men would choose to see a score higher than their own. The results on the measure of similarity indicated that men did judge themselves to be similar to a higher ranked person, whereas women showed no consistent preferences in their judgments of similarity. The results on the choice of a comparison other were not as clear-cut. 相似文献

Joseph L. Wetchler MS 《Contemporary Family Therapy》1986,8(3):224-240
School-focused problems present an interesting challenge to family therapists in that they take place in a system outside of the family. Treating the family without including the school often leads to a poor outcome. This article presents a macrosystemic model of treatment which views the family and school as an interacting system that maintains the ongoing problem. The therapist intervenes in this larger system by separately treating the family and school, then rejoining them to create a more functional working relationship. 相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources. 相似文献

Behavioral conceptions of alcohol abuse often include the hypothesis that drinking behavior is a negatively reinforced operant, with ethanol intoxication viewed as alleviating aversive environmental and internal states. This hypothesis has not been confirmed or refuted by previous studies which employed mild stressors and limited assessment methodology. In the present experiment, 22 patients with severe phobias approached their phobic animal under two consecutive conditions—first while sober and second after drinking either a placebo or an intoxicating dose of ethanol. The severe anxiety induced was assessed behaviorally, physiologically and by the patient's self-report of fear. The intoxicated patients did not experience decreased anxiety, tachycardia or avoidance, compared to the placebo group. These results have clinical implications and suggest the need to reconsider tension-reduction theories of alcohol abuse. 相似文献

Research investigating social values in interdependency situations has generally demonstrated age differences across the 5- to 10-year-old age range. However, the precise nature of these differences is unclear. Further, the differences in the social values of adults and children has not been addressed. The present study examined the social values of undergraduates and children using a measurement technique designed to allow an accurate inference of social values. Ninety-one 6- to 10-year-old children and 100 undergraduates rated the desirability of a set of outcomes which systematically varied with regard to the benefits to themselves and another person. Theoretically specified characteristics of the outcomes were then used to generate a regression equation predicting the desirability ratings separately for each individual. These regression equations were then clustered into groups of individuals who used decision rules characteristic of the major social values. The results indicate that the 8- to 10-year-old children, compared to the 6- to 7-year olds, more often expressed a social value involving equality and tended to less often express a social value involving superiority. Comparison of the social values expressed by the children and adults indicated that the adults more often expressed group-enhancement and individualism social values and less often expressed a social value involving superiority. 相似文献

According to single channel theory, the ability of humans to perform concurrent mental operations is limited by the capacity of a central mechanism. The theory was developed by analogy with early computers which had a single central processing unit and required sequential processing. These limitations are not likely to be properties of the mind. But now computers have begun to employ extensive concurrent processing, because of the decreasing cost of the necessary hardware. In this review we will try to bring the computer analogy up to date. Theoretical issues important for concurrent systems may be of interest to psychologists and have applications to such problems as the speed-accuracy trade-off. Several hypotheses about the way signals gain access to the central mechanism are reviewed. Recent variations of the single channel theory are discussed, including the hypotheses that more than one process can use the central mechanism at a time, and that some processes do not use the central mechanism and can be executed concurrently with those that do. In addition, relevant concepts from scheduling theory and operating systems theory are introduced and difficulties encountered by concurrent systems, namely complexity, deadlocks, and thrashing, are discussed. 相似文献
