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

Zusammenfassung Der Zusammenhang zwischen Blickwendung und Lidschlag wurde experimentell untersucht. Als wirksame Faktoren erwiesen sich die Größe der Blickwendung, die Kopfbewegung, die Art der Wahrnehmungsobjekte (Person — Gegenstand) und bei Personen der Grad der Aufmerksamkeitszuwendung. Über alle Versuchsbedingungen hinweg zeigte sich die relative Häufigkeit des Lidschlages bei der Blickwendung als individuell konstant.
The relationship between gaze movement and eye blink under various conditions
Summary The relationship between gaze movement and eye blink was investigated. The angle of eye movement, movement of the head, the type of objects perceived (person-object) and (when persons were viewed) the degree of attention were found to be relevant factors. Under all conditions studied, the relative frequency of blinking during gaze movement was shown to be individually constant.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

Object perception and object-directed reaching in infancy 总被引:1,自引:0,他引:1
Five-month-old infants were presented with a small object, a larger object, and a background surface arranged in depth so that all were within reaching distance. Patterns of reaching for this display were observed, while spatial and kinetic properties of the display were varied. When the infants reached for the display, they did not reach primarily for the surfaces that were nearer, smaller, or presented in motion. The infants reached, instead, for groups of surfaces that formed a unit that was spatially connected and/or that moved as a whole relative to its surroundings. Infants reached for the nearer of two objects as a distinct unit when the objects were separated in depth or when one object moved relative to the other. They reached for the two objects as a single unit when the objects were adjacent or when they moved together. The reaching patterns provided evidence that the infants organized each display into the kind of units that adults call objects: manipulable units with internal coherence and external boundaries. Infants, like adults, perceived objects by detecting both the spatial arrangements and the relative movements of surfaces in the three-dimensional layout. 相似文献

Electrophysiological methods were used to examine 52 ward patients with a long history of alcohol abuse. Alertness fluctuations were much more common in the EEG than among the healthy control subjects. 86.5% of the ENG findings were abnormal and indicated demyelinisation in most cases. The latence times of the brain stem potentials were longer than normal in about half of the patients and were definitely pathological in 13.5%. There was no statistical correlation between drinking habits and the results of the examination. Unknown pathogenetic factors are therefore suspected. The polytopic pattern of damage necessitates the use of a broad range of signostic techniques. 相似文献

Neurophysiological examinations of 100 long term alcohol dependent patients who were having neuropsychiatric treatment, showed symptoms of polytopic damage of the peripheral and central nervous system. The results show that for recognition of the damage an extensive diagnostic programme must be used. 相似文献
