The latency of the perception of the dark spot at the intersection of a Hermann grid was measured before and after dark adaptation. It was found that dark adaptation significantly increased the latency of perception of the spot while light adaptation had no effect. This finding was predicted from the Jung and Spillman account of the Hermann grid illusion and from the Kuffler et al. finding that inhibitory receptive fields of the cat’s retinal ganglion ceils are reduced in size and responsiveness after dark adaptation. The significance of this finding in relation to other simultaneous contrast phenomena is discussed. 相似文献

This paper outlines portions of the writer's therapeutics in the field of stuttering with emphasis upon use of masking the hearing of stutterers as a part of a total therapeutic approach. Commencing with devices providing continuous noise to override the voice of the stutterer so that he cannot hear himself and, thus, eliciting fluency. Described is the use of the voice actuated Edinburgh Auditory Masker within an intensive stuttering program in a prison setting since September 1978. It is concluded that the use of masking and the Edinburgh device has been helpful and productive with severe stutterers. 相似文献

A system is described which eliminates manual coding and punching of computer data cards in a psychophysical experiment. Conventional relay logic is used to control the operation of a card punch and to enter data in selected card columns. 相似文献

To determine the manner in which the equidistance tendency (ET) varies as a function of time, 10 Ss tracked the perceived position of a monocular test object viewed in a binocular field consisting of two rectangles which differed in perceived size and distance.Variables investigated were the temporal order of rectangle appearance and disappearance which determined whether or not opposingETs existed, luminance and repetition interval of the 20 msec test object. It was found thatET effects occur gradually over time, that opposingETs retard the rate at which the test object changes its perceived locus, and that elapsed time rather than total observation time was critical in determining how great a change in perceived locus of the test object occurred. Implications of these findings were discussed. 相似文献

Forty Ss, previously classified as introverts or extraverts on the basis of scores on the Eysenck Personality Inventory, performed a visual vigilance task while being stimulated with noise at an intensity level of either 65 or 85 dB. Introverts given noise of 65 dB intensity showed an improvement in detection rate across trials, whereas introverts given noise of 85 dB intensity showed a decline in detection rate. Extraverts responded to noise of 65 dB intensity with a slight decrease in detection rate, but showed an improvement in detection over trials when noise of 85 dB intensity was given. When noise of the lower intensity was given, introverts showed greater sensitivity to signals than extraverts. When noise of the higher intensity was given, introverts and extraverts were equal in sensitivity. The results are discussed in terms of a hypothesized relationship between stimulation and arousal, with E-I as a moderator variable. 相似文献
