Drawings done by a patient before examination led to the suspicion of cataphasia, in view of previous experience of similar pictures drawn by verbigerate patients, and this proved to be so. We assume that the verbigerate affection of the thinking process is pictorially reflected in spontaneous casual drawing. In a less spontaneous situation, on other hand, the patient will not be so completely disorganised, and thus the author of an utterly confused drawing can still retain some measure of mental control in the course of tests. 相似文献

A 41-year-old male patient is presented with a lesion in the anterior cingulate cortex, medial orbital cortex, and rostral striatum bilaterally and supplementary motor area on the left side. The patient first exhibited a state of akinetic mutism which lasted about 6 weeks. During this state, no volitional vocal utterances were made; there were, however, occasional groans of pain. During recovery, the mute phase was replaced by a state in which the patient could whisper but not phonate verbal utterances. About 10 weeks after the accident, phonation was restored. The speech was characterized, however, by monotonous intonation and a very low frequency of spontaneous utterances. While the frequency of spontaneous speech improved noticeably during the following months, emotional intonation remained permanently defective. A comparison of the present case with other cases from the literature as well as experimental monkey data suggest that the anterior cingulate cortex is involved in the volitional control of emotional vocal utterances. 相似文献

Semantic activation due to priming, and the time course of its dissipation, were examined. Following a word presentation, the subject performed one of three tasks: synonym, antonym, or rhyme production. The first presentation of a word together with the task was the primer. The second presentation of the same word occurred after 0 to 4 intervening words. Effects of priming were looked for in the speed of the first response to the second presentation of the word. A production facilitation occurred when synonym production was primed by antonym production to the same word, the primed word immediately following the primer. Facilitation decreased with increasing number of interpolated tasks. No effect was found when antonym production was primed by synonym production to the same word. The results are discussed in terms of spreading-activation due to active use of the associative link between the concept and its antonyms. 相似文献

Subjects recalled names of countries during 8 or 5 min. (Experiments 1 and 2) or performed a set of brief (40 sec) tasks recalling items from semantic or factual memory (Experiment 3), either in silence or in intermittent white noise (95 dB (A)). Noise interfered consistently with the performance of "neurotic" subjects (i.e., subjects scoring above the median on the EPI scale of neuroticism) but had little effect on that of "stable" ones. Performance was not significantly related to extraversion, nor to self-rated activation, and it was uncorrelated with neuroticism in the no-noise condition. An interpretation of the results emphasizing the distracting effects of noise is discussed. 相似文献

QUANTITATIVE PSYCHOPHYSICAL AND ELECTRO-PHYSIOLOGICAL DATA ON SOME ODOROUS COMPOUNDS 总被引:1,自引:0,他引:1

D rake , B., J ohansson , B., von S ydow , E. & D øving , K. B. Quantitative psychophysical and electrophysiological data on some odorous compounds. Scand.J. Psychol ., 1969, 10 , 89–96.—Magnitude estimations of odor intensity, and electrophysiological responses from frog olfactory epithelia, were obtained for dilution series of 8 odorous compounds. Comparing of data with each other and with known vapor phase concentrations showed relations between pooled psychophysical data and vapor phase concentrations, and between electrophysiological data and vapor phase concentrations, describable by power functions (exponents 0.26–0.50 and 0.18—0.39). There were also high correlations between electrophysiological data and individual as well as pooled psychophysical data. The results give an impression about the feasibility of using a biological detector in gas chromatography. 相似文献

The retention of memorized weights was repeatedly tested by the reproduction method, the subject's state of adaptation for weight being systematically changed between the tests. The reproduction scores were found to vary as approximately linear functions of the adaptation level. This relationship was unaffected by changes in the degree of learning of the memorized weight and in several other variables. The 'anchoring' and retention of weight, and different indicators of adaptation level, are discussed. 相似文献

An experiment was performed to test the following prediction: If a pattern is learned in terms of 'schema with correction', and the subject's conception of the figural schema is changed during the retention interval, the 'memory' of the pattern will change correspondingly. Following the repeated presentation of a pattern S , and the memorization of a related pattern A , patterns deviating from S more and more in a predetermined direction were interpolated. This led to a highly significant systematic error of the predicted kind in the subject's performance when he subsequently was given a recognition test for A. 相似文献

When a series of reproductions of an interval is made in the absence of a standard the judgements progressively lengthen. The similarity between stimulus conditions in this type of time estimation experiment and the conditions which produce a decrement in human vigilance is discussed. It is argued that failure to detect cues for the passage of time reduces the amount of time perceived to elapse. Reproduced judgements must consequently be increased in length to match remembered standards. The hypothesis is then made that the kind of variation in background stimulation which facilitates vigilance should increase the frequency of detection of cues for duration and reduce reproduced judgements. This hypothesis is tested with 80 subjects and a reversal of the serial reproduction effect is found on trials with changed background conditions. 相似文献
