A microcomputer-based system is described for the automatic acquisition, storage, and analysis of rodent food intakes. The feed-o-meter provides reliable, valid measurements of consumption, with minute-by-minute accuracy of ?.03 g. 相似文献

Speech phobic subjects received five treatment sessions under either positive or neutral expectancy set. Therapy conditions included hierarchy exposure with contiguous relaxation (desensitization), exposure with noncontiguous relaxation, exposure only, and no-treatment. Expectancy had virtually no outcome effects. Desensitization was superior to the other conditions on subjective outcome measures. In contrast to the two exposure conditions without contiguous relaxation, desensitization resulted in increased imagery vividness, greater cardiovascular response to the first visualization of the initial hierarchy scene, and greater declines in cardiovascular response within repetitious visualizations of scenes and across initial visualizations of increasingly anxiety-provoking scenes. Expectancy significantly influenced both fear ratings and cardiovascular response to scenes during the first session, the latter effect disappearing after the first session. The results are discussed in terms of recent theorizing regarding the role of relaxation and expectancy in desensitization. 相似文献

Can alcohol reduce tension? 总被引:1,自引:0,他引:1
The Tension Reduction Hypothesis of alcohol use is examined in the light of recent criticism. Contrary to the conclusions of Cappell and Herman (1972) it is argued that the hypothesis is supported by evidence from animal research in most cases where an appropriate paradigm has been employed. 相似文献

Previous research has failed to show consistent effects upon memory performance of individual differences in the use of mental imagery. A test of pictorial memory was devised which varied the ease with which the stimulus patterns could be verbally encoded. A factor analysis related performance in this task to a variety of other individual characteristics. The recall of material which could not be readily verbalized defined a factor within the solution which showed significant loadings of age and performance in the Progressive Matrices, but not of subjective ratings of the vividness of experienced imagery. The recall of material which could be readily verbalized did not contribute to the factorial structure of the results. It was concluded that the two sorts of pictorial material are remembered in quite different ways. 相似文献

Subjects were required to recall lists of six words which had been presented visually in sequence. One or two of the words might be plural nouns. A substantial number of errors occurred in which the plural form became detached from its original root. This is taken as evidence for a morpheme-based code as opposed to a unitary word code. A significantly high proportion of these errors maintained the form of the plural ( /S/, /Z/ or (ЪZ/) which is considered evidence for a primarily phonological coding of the plural morpheme. There is however a suggestion that on some occasions the plural is coded morphemically—i.e., in a way which does not distinguish between the various plural endings. 相似文献
