In the first of two studies, the responding of four albino rats was differentially reinforced in the presence of noise and light together and then tested in the presence of the noise and the light separately during extinction. The light exercised substantially more control of responding than did the noise. In the second study the responding of a similar group of four rats was differentially reinforced in the presence of the noise and the light separately. Control of responding by the light developed more rapidly than control by the noise. Results suggest that levels of control by stimuli after differential reinforcement with respect to the stimuli together can be predicted by the rates of development of control during differential reinforcement with respect to the stimuli separately. 相似文献

This study asked the question: What are the role expectancies of treatment personnel in the treatment community and are they consistent across patients' emotional condition? An 83-item inventory was developed and administered under three different sets of instructions, each characterizing a different patient condition. Treatment staff and administrators were asked to rate items on the basis of the level of expectancy they held for their team vocational rehabilitation counselor. The analyses suggest that treatment staff and counselors do not agree on role expectations and that patient condition is a significant mediating variable. 相似文献

Three experiments are reported, which are attempts to replicate the finding of Ross and Gregory (1964) that difference thresholds for weights can be lowered by means of the size-weight illusion. Three different procedures were used, the first one (experiment I) being designed to show whether or not changes in a subject's judgement criterion could account for apparent changes in sensitivity. The second method (Experiment II) was a replication of Ross and Gregory's first procedure, in which the standard weight was judged before the comparison. In Experiments I and II a larger illusion was induced than in the original studies, but in Experiment III both the weights and container sizes were practically identical to those used by Ross and Gregory. The procedure was also the same as their most successful procedure (number 3) in which standard and comparison were judged simultaneously. The findings were uniformly negative: there was no evidence of criterion shift when the size-weight illusion was induced nor did we find the lowering of threshold previously reported. 相似文献

As a more junior Fellow of the same college in Cambridge as Sir Frederic Bartlett, I am especially glad of this opportunity to join with members of the Experimental Psychology Society in honouring him. It would be superfluous for me to speak here of Sir Frederic's academic achievements: so many of our members are engaged in research on problems which sprung from his pioneering work, and his influence on the development of psychology as a science certainly needs no elaboration by me. But I would like to make one personal remark. I suppose all younger men feel that there are just a very few members of the preceding generation who have achieved a stature which will always be beyond the reach of any of their own contemporaries. Sir Frederic has always been one of those for me. I am speaking here not only of his academic achievements, but of his kindness as a man; and I would like to tell him how much I valued his willingness to share some of the benefits of his experience when I was blundering about on the borders of his subject. 相似文献
