This paper discusses a questionnaire survey done with a sample of 130 systemic family therapists, which investigated their training in, and experience of, working with lesbian and gay male clients and attitudes towards lesbians and gay men using the Index of Attitudes to Homosexuals. The findings indicate that the majority of respondents had received relatively little training in working with this client group within their systemic training. It also indicated that their attitudes towards lesbians and gay men generally may have been influenced by the degree of social, professional or familial contact that they had with them. 相似文献

ABSTRACT— Although it is estimated that as many as 4% of people experience some form of enhanced cross talk between (or within) the senses, known as synaesthesia, very little is understood about the level of information processing required to induce a synaesthetic experience. In work presented here, we used a well-known multisensory illusion called the McGurk effect to show that synaesthesia is driven by late, perceptual processing, rather than early, unisensory processing. Specifically, we tested 9 linguistic-color synaesthetes and found that the colors induced by spoken words are related to what is perceived (i.e., the illusory combination of audio and visual inputs) and not to the auditory component alone. Our findings indicate that color-speech synaesthesia is triggered only when a significant amount of information processing has occurred and that early sensory activation is not directly linked to the synaesthetic experience. 相似文献

Since genetic information has implications for family members, some choices about genetic risk may be influenced by perceptions
of responsibility to relatives. Drawing upon 25 semi-structured interviews with test recipients in Canada, this study explored
decisions about inherited breast-ovarian and colon cancer. Qualitative data analysis revealed the pervasive significance of
genetic responsibility in test decisions. We highlight three dimensions of genetic responsibility: 1) to know about the self
for self; 2) to know about the self for others; 3) to know about the self to oblige others to know. It is argued that these
dimensions of genetic responsibility have implications for test decisions, family relationships and other family members’
desire to know (or not know) and to act (or not act) with respect to their own genetic risk. In particular, genetic responsibility
may play out as a framing of a relative’s moral obligation to know their risk that could obviate any interest they might have
in not knowing. We conclude that perceptions of responsibility to—and of−other family members be thoroughly explored in genetic
counseling sessions. 相似文献

Arguments from the Logical Problem of Language Acquisition suggest that since linguistic experience provides few negative data that would falsify overgeneral grammatical hypotheses, innate knowledge of the principles of Universal Grammar must constrain learners hypothesis formulation. Although this argument indicates a need for domain-specific constraints, it does not support their innateness. Learning from mostly positive data proceeds unproblematically in virtually all domains. Since not every domain can plausibly be accorded its own special faculty, the probative value of the argument in the linguistic case is dubious. In ignoring the holistic and probablistic nature of theory construction, the argument underestimates the extent to which positive data can supply negative evidence and hence overestimates the intractability of language learning in the absence of a dedicated faculty. While nativism about language remains compelling, the alleged Logical Problem contributes nothing to its plausibility and the emphasis on the Problem in the recent acquisition literature has been a mistake. 相似文献

A stepwise change in the frequency of a continuous pure tone is taken as an element signal. The detectability of a single step is compared with the detectability of a pattern composed of two such steps in order to determine the ways in which the steps interact and how these interactions depend upon the time interval between the steps. It is shown that two positive steps separated by D msec interact by summation (d’ for two steps being greater than d’ for a single step) and that this summation is 100% even when D=100 msec. The extent of summation decreases as D is increased beyond 100 msec, leveling off at about 40% when D is near 1,000 msec. A positive step followed by a negative step (an increment) presents a more complex picture. When D=0 msec, the pattern is the null signal, and, of course, the two steps subtract completely. As D is increased, the extent of subtraction decreases, becoming zero when D is about 400 msec. Increasing D beyond 400 msec results in summation, reaching about 40% when D=2,000 msec. For D less than about 1,000 msec, the sign of the second step in a two-step signal is important: two steps of like sign summate, and two steps of unlike sign subtract. However, when the two steps are separated by about 2,000 msec, the sign of the second step is irrelevant: summation occurs, and the extent, about 40%, is the same for two steps of like sign and two steps of unlike sign. A brief theoretical discussion stresses the extant need for an information-processing theory of signal detection. 相似文献

Pigeons were studied in an experiment involving two concurrently available response keys. Conditions were such that in the first condition the predictions of melioration (Herrnstein & Vaughan, 1980), minimization of deviation from matching, and maximization were identical: relative time on the right key should have fallen between .125 and .25, which in fact occurred. In the second condition, melioration predicted a shift in relative time on the right to between .75 and .875, which would involve a transient deviation from matching as well as a substantial drop in rate of reinforcement. All three birds eventually shifted their distribution of behavior to within the range predicted by melioration. 相似文献

The orientation of a subject’s eyes can be automatically sampled in real time at 60 Hz using Mackworth’s corneal reflection method, a closed circuit TV system with a brightness-amplitude trigger, and a minicomputer. The organization of the electronic interface and software (for recording and behavioral control) is described, along with the characteristics of the recording system and potential sources of artifact. Sample calibration and experimental data are presented. 相似文献
