Two experiments employing the release from PI method were conducted to determine whether degree of release could be predicted by the amount of denotative attribute overlap between the control and experimental groups. This theory was very appropriate for predicting the results of the first experiment, but was less successful in the second unless a connotative attribute is also introduced. It is suggested that this class of attribute should be included in semantic memory conceptualization. 相似文献

Male gerbils have larger ventral scent glands, and they mark more than females. In both sexes, scent gland activity is dependent on gonadal hormones. Observations on colonies of gerbils, living in enclosures or cages, showed that both scent gland size and marking behaviour were related to social status. In colonies founded by a single pair, breeding was confined to the original female. The infertility of the daughters was due to failure of sexual maturation. As this was always associated with a lack of development of the scent glands, the functional state of the latter could be used as an index of fecundity. A change in social organization (eg removal of the parents) caused previously infertile females to conceive and was accompanied by development of the scent glands If there was competition for dominance, the scent glands of the losers regressed; at autopsy, their ovaries and uteri appeared to be nonfunctional. The founding father usually had a larger scent gland than his sons, but the inhibition of sexual function was not as severe as in the females. However, the father characteristically showed much more marking behaviow in a neutral territory than his sons. None of the fem ales-except the mother-showed appreciable marking, and her scores were much lower than those of the dominant male. Asymptotic populations were reached at about the same level in enclosures and cages, implicating an intrinsic capacity for control independent of the number of animals per unit of space but probably related to the natural size of a social group. Stabilization of numbers was achieved not only by reproductive inhibition of young females, but also by cessation of breeding by the founding mother and death of litters. Littermates raised in enclosures without their parents showed delayed sexual maturation accompanied by fighting which resulted in the formation of a hierarchy headed by a breeding female and a dominant (marking) male. 相似文献

ABSTRACT: In an attempt to determine the extent to which crisis centers meet the needs of black communities, questionnaires were sent to 12 centers. Responses were received from six. Only two centers, in Nashville and Washington, D.C., had statistics of callers identified by race. The findings from these two centers indicate that there are differences between the white and black callers with regard to age, marital status, and type of problem. As an example, the typical black male caller was older and more concerned about his job and financial problems than were white males. This kind of information suggests a need for expanded services within the crisis center framework, possibly for a more preventive approach. More data gathering concerning the black community using crisis centers is urged in order better to identify the needs of this population and the methods to be used for meeting those needs. 相似文献

This paper highlights the role of music in psychic change through a clinical case. A patient, who was initially distant and cold, started to talk about music. An enactment around the analyst’s comment about a famous conductor, started an exchange of music “notes” that changed the course of treatment. For the analyst, it brought old memories and musical reveries. For the patient, music allowed him to be in touch with undiscovered parts of himself and losses that had not been mourned. There was a mutual personal transformation and expanding awareness of self and other for both participants.

Few studies have evaluated the use of assessment to identify the most efficient instructional practices for individuals with autism spectrum disorder. This is problematic as these individuals often have difficulty acquiring skills, and the procedures that may be efficient with one individual may not be for others. The experimenters conducted instructional assessments to identify the most efficient prompt type (model, partial physical, full physical) and prompt-fading procedure (progressive delay, most-to-least, least-to-most) for teaching auditory–visual conditional discriminations for individuals with autism spectrum disorder. Each assessment was conducted at least twice, and a final generality test combined the most and the least efficient prompt type and prompt-fading procedure for teaching novel auditory–visual conditional discriminations. The results demonstrated learner-specific outcomes for the prompt type assessment, whereas the least-to-most prompt fading procedure was most efficient for all participants. 相似文献

The purpose of the current study was to evaluate the effect of implementing differential reinforcement at different times relative to the onset of teaching new skills to learners with autism spectrum disorder. Specifically, we first determined the most efficient differential reinforcement arrangement for each participant. Using the most efficient arrangement, we evaluated if differential reinforcement from the immediate onset, early onset, or late onset is the most efficient for learners to acquire a new skill. Three children diagnosed with autism spectrum disorder who have a history of receiving intervention based on the principles of applied behavior analysis participated in this study. The immediate onset of differential reinforcement resulted in the most efficient instruction in 6 of 7 comparisons. The results are discussed in light of previous studies and suggestions for future research are provided. 相似文献

In three studies, we examined how individuals evaluate a rape victim based on whether she reports or does not report her rapist. Across all three studies, a victim who did not report the perpetrator was evaluated more negatively than a victim who did report the perpetrator. In Studies 2 and 3, symbolic concerns (the view that the victim’s actions violated shared values and disempowered herself) mediated the effect of reporting on evaluation of the victim. The effects of the victim’s relationship to the perpetrator (Study 1) and the victim’s decision to forgive the perpetrator (Study 2) were also examined. Results indicate that observers evaluate victims who do not report their perpetrators more negatively, and that this evaluation may be the result of perceptions of not reporting rape as a transgression. 相似文献
