This paper describes a permanently implanted device for applying cold to localized parts of the brain surface in order to produce reversible functional lesions in behaving animals. It consists of an array of several independently controlled stainless steel tubing loops, each shaped to fit a separate brain area. Cooled alcohol is pumped through the tubing and temperatures are monitored with attached thermocouples. Implanted loops can be cooled to 0°C within 15 sec, and temperatures can be maintained at ±1°C of accuracy. Tissue tolerance is excellent: Implants have been demonstrated to last up to 1 year or more. Methods and materials for construction are discussed. 相似文献

In a previous investigation, we demonstrated the role of questions as an instructional resource in the social construction of conversation by depriving conversationalists of their use. The resulting conversational structure, measured in terms of the ability of third parties to reconstruct the dialogues after they had been randomized, was impaired. The importance of culturally shared knowledge for the reconstruction (and by implication the construction) task was apparent in the superiority of British over Canadian subjects in reconstructing unconstrained British dialogues. The present study was concerned with the effects of privately shared knowledge on the construction of conversation. Conversational structure and the frequency of questions were greater in strangers' than in mutual acquaintances' unconstrained dialogues. Strangers' dialogues, but not those of mutual acquaintances, were disrupted under a ban on questions. The results were taken to indicate that strangers need to provide one another with continual instruction in how to proceed, whereas mutual acquaintances, in virtue of their privately shared social knowledge, can construct orderly dialogue with less moment-to-moment guidance. 相似文献

This study looks at some effects of five different styles of women's clothing: Formal Skirt, Formal Pants, Casual Skirt, Casual Pants, and Jeans. There were no significant differences in compliance to a request to fill out a questionnaire made by experimenters dressed in the five clothing styles, although experimenter age and sex effects were found. Ratings of photographs of the five dress styles indicate that a model was viewed by both male and female subjects as most happy, successful, feminine, interesting, attractive, intelligent, and wanted as a friend when wearing a Formal Skirt outfit and as least so when wearing Jeans. She was also seen as more active when wearing pants as compared with a skirt. Subjects' reasons for choosing what clothing to wear did not indicate that how one will appear to others is the major factor in clothing selection. It appears that clothing does communicate something about the wearer but may influence behavior toward her primarily in the absence of other information about her status. 相似文献

Scientology's founder, L. Ron Hubbard, frequently made claims that Scientology was related to or shared significant similarities with Hinduism, Theravada Buddhism and Taoism. However, careful examination of Hubbard's claims indicates that he had only a superficial acquaintance with Eastern religions, and most of his attempts to associate Scientology with these faiths are unwarranted. Moreover, social and political pressures against his organisation's alleged healing practices probably provided the catalyst for Hubbard's attempt to portray his creation as a religion with Eastern overtones. 相似文献

Reasons for unsafe sex were examined using an illusions of control framework. Heterosexual college students (N= 301) and gay men (N= 248) were surveyed regarding perceived control over exposure to HIV, of vulnerability to HIV, use of illusory control in chance situations, and real and illusory strategies for protection against HIV. As predicted, the use of illusory control in chance situations was associated with more illusory HIV protection in both samples. Illusory protection strategies were associated with feeling less vulnerable to HIV which was mediated by perceptions of control over exposure to HIV. Suggestions for intervention include providing information about the illusory nature of some protective strategies and a focus on failing to protect oneself from STDs. 相似文献

Imitations of 15 synthesized vowels, some like English vowels and some not, were obtained from nine adults and ten 6-year-old children. Estimates of the first three formant frequencies (F

) were made from spectrograms of the vowel imitations. The reliability of reproduction was assessed by calculating standard deviations for five imitations each of ten of the synthetic stimuli. Generally, both the intrasubject and intersubject variabilities were greater for the children than for the adults. However, the differences in intrasubject variability between the two groups often were not much greater than the difference in measurement error which would be expected for voices of different fundamental frequencies. Subjects tended to reproduce the nonEnglish vowels less reliably than the English vowels, although the adults were less influenced by phonetic familiarity than were the children. Vowel familiarity appeared to be especially important for reliable reporoduction of the F

Two hundred seventy nine individuals served as mock jury members in a civil trial that involved multiple plaintiffs and several expert witnesses. Juries were or were not provided with written summary statements of the testimony of expert scientific witnesses, and were either permitted or not permitted to take notes. The results showed that the combination of summary statements and note‐taking had a synergistic effect on the quality of decision‐making. Mock juries enabled by both cognitive aids provided significantly higher awards, as compared to mock juries aided by one or none of the jury‐aids, to the most severely injured plaintiffs without increasing compensation for those less worthy. Aided mock juries also recalled more probative evidence than non‐aided jurors, and were more satisfied with the efficacy of their deliberations. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

There is increasing evidence to suggest that mental simulations underlie many cognitive processes. We review results from three rapidly developing research areas suggesting that simulations underlie information retrieval. First, neuroimaging work indicates that cortical circuits that were activated during encoding are reactivated during retrieval. Second, retrieval is aided by behavioural re-enactment of processes involved in encoding, including re-enactment of encoding eye movements. Third, the time courses of encoding of visual features and the retrieval of information about those features are related. Overall, the evidence suggests that the often observed interactions between encoding and retrieval result from a cognitive system that, at least partially, reactivates processes that were involved in encoding to retrieve information. 相似文献
