Summary A study was conducted on the effects of off-task cognitions on performance during sleep deprivation. Subjects answered the Thought Occurrence Questionnaire, assessing their proneness to engage in off-task cognitions, and were deprived of sleep for 72 hours, during which they performed a variety of tasks including visual discrimination and three versions of a logical reasoning task in which cognitive load was varied systematically. In addition, every day subjects answered the Cognitive Interference Questionnaire, which taps off-task cognitions during the experiment. Results indicated that subjects who habitually engage in off-task cognitions performed worse during 72 hours of sleep loss than subjects who do not engage in such distracting activities. In addition, it was found that the engagement in off-task cognitions increased during the 72 hours of sleep loss and such an engagement was related to deficits in performance accuracy. The mechanisms of off-task cognitions and sleep loss underlying these effects are discussed. 相似文献

Two predictions, viz., that for Austrian non-clinical school children whose left-right reading-writing habits parallel an assumed innate left-right drawing tendency, a clear preference for left-right execution of 4 Bender-Gestalt figures (Nos. 1, 2, 3, 6) would be attained at an earlier age and no plateau would be observed in contrast to Israeli non-clinical school children whose right-left reading-writing habits are in a direction opposite to the assumed innate drawing tendency, were confirmed at significant levels of confidence. In a sub-sample of the Austrian population investigated fathers' educational/occupational level as well as the child's position in his sibship as measures of attention and stimulation in the home do not appear to have any significant influence on preference for direction of drawing. 相似文献

Despite the importance of the assessment of ego strength for appropriate assignment of clients for psychotherapy and/or rehabilitation, existing techniques have not fulfilled expectations. A method for assessing ego strength through the Rorschach Test independent of clinical criterion is proposed. In addition to certain variables of Klopfer's RPRS (M+, FM+, FC+ plus CF+), sharply preceived space responses are included. They constitute a highly intercorrelated global measure of ego strength and are also highly correlated to a relatively independent Rorschach variable of global ego efficiency, i.e. integrated whole responses. In accordance with prediction, non-controlled color responses as well as accuracy of form perception did not correlate in a non-clinical sample with either measure of ego strength. 相似文献

The present study attempted to eliminate the word superiority effect found in letter search by holding the target letter fixed across trials. The expectation was that the target would thereby become so familiar and salient that the subject would "see" only that letter during search. Even with the target-letter held fixed (Experiment I), however, search was still faster through words than through nonwords, indicating that nontarget letters had been "seen" as well. Search also remained faster through words than through nonwords when the number of exposures to the target was further increased by having the subject search for the absence rather than the presence of the target letter (Experiment III). In line with the notion of "proofreader's errors," however, search became relatively more accurate on nonwords than on words when it required detection of the "mutilation" produced by substituting an F for an E, e.g., BASKFT, BAKFRY (Experiment IV). 相似文献

Transparent mirror glass can be used to construct inexpensive and highly reliable timing shutters for stimulus-presentation systems. A representative circuit and a simple stimulus-display device using 3 × 5 index cards are also described. 相似文献

This study examined the interrelationships among role conflict, gender role orientation, and female sport participation. One hundred six female high school athletes and nonathletes were administered the Personal Attributes Questionnaire and a role conflict inventory. Multivariate analyses revealed that athletes experienced significantly higher levels of role conflict than nonathletes, but a nonsignificant relationship was found between role conflict and gender role orientation. Role conflict was also unrelated to type of sport, although team athletes high in feminine orientation perceived higher role conflict than low feminine oriented athletes. Overall, levels of perceived and experienced role conflict were low. In sum, role conflict does not appear a major concern for adolescent female athletes nor was gender role orientation a factor related to conflict between the roles of female and athlete. 相似文献
