A questionnaire was mailed to every marriage counselor, child guidance specialist, and psychologist listed in the yellow pages of Florida telephone directories. The replies were used to describe the profession of private practice counseling. Sixty-seven percent of the sample replied. It was found that several professions offer counseling as a service, but there is not yet an established profession of private practice counseling.  相似文献

Visual screening, a mildly aversive response suppression procedure, was evaluated across two studies for its effectiveness in reducing topographically similar and dissimilar stereotypic behaviors of four developmentally disabled children. In the first study, a multiple baseline design across subjects and behaviors was used to assess the effectiveness of the procedure as a treatment for reducing the visual and auditory self-stimulatory responses of two 9-yr-old mentally retarded and behaviorally disturbed children. A multiple baseline design across subjects was used in the second study to evaluate the effectiveness of visual screening as a treatment for reducing stereotypic fabric pulling and self-mutilative ear bending, respectively, of two 13-yr-old mentally retarded, autisticlike adolescents. Long-term follow-up data for both studies were reported. The results suggested that visual screening was an easily administered, effective, and exceptionally durable treatment procedure for controlling a variety of stereotypic behaviors commonly associated with the developmentally disabled.  相似文献

We examine the form of distributions of simple reaction time. The stimuli we use are the offset of weak pure tones masked by wide-band noise. The hazard functions of the RT distributions (i.e, the probability of a response given that one has not already occurred) are monotone increasing for very weak tones but become peaked for stronger tones. Of the models available in the literature, none is very satisfactory, although two can account for the general qualitative shape of the peaked hazard functions. We propose a model wherein both a change and a level detector function in parallel. If one assumes that the change detector and level detector have slightly different thresholds, this model can account for both the monotone increasing and the peaked hazard functions.  相似文献

Divided attention: the whole is more than the sum of its parts   总被引:3,自引:0,他引:3  
A divided attention situation is more than the sum of its component single tasks. Emergent aspects of the whole situation must also be considered. Three examples illustrate this. (a) When several complex stimuli (e.g., letters) are identified at once, their perceived components or features must be appropriately bundled together. Otherwise, components of two different stimuli may appear combined. This (emergent) problem is shown to depend on attention to multiple stimuli, not simply their presentation. (b) In the psychological refractory period (PRP) situation, especial difficulties arise when stimulus-response mappings are different for first and second reactions. It appears that for each reaction there is some (emergent) uncertainty over which mapping to use. This is only one of many possible emergent processes in the PRP situation. (c) When the two hands perform different actions (internally programmed sequences of taps), there is some tendency for each hand to carry out the action assigned to the other. This again is only a small part of the (emergent) problem of motor coordination. Thus the simple idea of competition for limited resources captures only a part of the problem of divided attention. Performance under divided attention will reflect an interaction between resource limitation, single task processes, and emergent aspects of the whole situation.  相似文献

This article introduces a non-human version of the non-identity problem and suggests that such a variation exposes weaknesses in several proposed person-focused solutions to the classic version of the problem. It suggests first that person-affecting solutions fail when applied to non-human animals and, second, that many common moral arguments against climate change should be called into question. We argue that a more inclusive version of the person-affecting principle, which we call the ‘patient-affecting principle’, captures more accurately the moral challenge posed by the non-identity problem. We argue further that the failure of person-affecting solutions to solve non-human versions of the problem lend support to impersonal solutions to the problem which avoid issues of personhood or species identity. Finally, we conclude that some environmental arguments against climate change that rely on the notion of personal harm should be recast in impersonal terms.  相似文献

This study examined 21 American Indian students’ postsecondary transition and retention experiences through a phenomenological methodology. Postsecondary transition is the process of leaving home and adjusting to postsecondary education. Postsecondary retention is achieving success and remaining at a university for at least 6 months. Data sources included individual interviews, journal analysis, and document analysis. The 10 emergent themes described an interconnected phenomenon centered on institutional, social, and interpersonal dimensions.  相似文献

The revised version of the Barrett-Lennard Relationship Inventory with an added advice-giving scale was given to 240 female and 95 male students, who completed it in terms of their current closest personal relationship. The correlations between the 80 items were factor-analysed using a principal-factor solution to determine whether the items represented the five postulated factors of advice-giving, empathy, congruence, and level of and unconditionally of regard. Eighteen factors were extracted and rotated by the Varimax method. The first five factors extracted accounted for 36.3% of the variance and reflected the five postulated factors, thus partially supporting the factorial validity of this questionnaire.  相似文献
