A general on-line eye-movement recording system is described which consists basically of (a) some on-line instrument capable of displaying a visual scene, (b) a device to measure eye position and output position information in the form of electrical signals (c) an analogue-to-digital converter, and (d) a computer. General software for such a system is discussed with emphasis on subroutines which perform calibration and which continuously monitor eye position. 相似文献

Body (ear) temperature of 14 subjects was lowered in order to examine its effect upon performance of a task requiring estimation of an interval of 60 s. Although there was some evidence that subjects counted more slowly at lower body temperatures, the inconsistency of the effect was such as to cast doubt on the hypothesis of a “biochemical clock” or “metabolic pacemaker” in the brain said to subserve human time estimation of brief intervals. 相似文献

Four experiments investigated the role of pattern goodness in backward masking using five- and four-dot patterns constructed by placing dots in the cells of a 3 x 3 matrix. In Experiment 1, subjects rated the goodness of these patterns and the results replicated previous work showing that good patterns had few alternatives. In Experiment 2, the dot patterns were the target stimuli in a backward masking task using a variety of masking stimuli. For all masking, good patterns were reproduced more accurately than poor patterns. In Experiment 3, the goodness of the masking stimulus was varied. The results indicated that good patterns were reproduced more accurately (replicating Experiment 2) and that good patterns were less effective as stimulus than were poor patterns. In Experiment 4, a long interstimulus interval which precluded masking was used to determine whether goodness affected encoding or memory. At these intervals, there were no differences among patterns, suggesting that the effect of pattern goodness was on rate of encoding. These results demonstrate the importance of configural properties in pattern perception. 相似文献

The efficiency of (a) a school readiness test, (b) mental age, and (c) specific sensory and perceptual skills was tested as predictors of word recognition at the end of the first school year. Five hundred and eigth children in four schools with three significantly different socioeconomic backgrounds were tested in kindergarten. Two schools were in the same middle-class area: one was a traditional classroom school, the other was open space in structure. When the variables were examined by means of stepwise regression analysis and partial correlations, the school readiness test appeared as the most efficient predictor in each of the four schools, as well as in the total group. Mental age and auditory skills ranked either second or third in importance depending on the school situation. 相似文献

The event-related potential (ERP) was recorded to identify the time epochs during which different independent variables have their effects on stages in a memory search task. Stimulus intensity, memory set size and response type were varied. For the most part, the order and timing of effects (evaluated by Principal Components Analysis of within-subjects ERP differences) were consistent with the presumed underlying stages, except for early effects of response type prior to memory set effects (suggesting precategorical target recognition). The usefulness of this type of analysis for the investigation of information processing stages is discussed. 相似文献

Two hypotheses are evaluated in thisinvestigation of gender differences in the attitudinaland behavioral correlates of sexual risk. Thedifference in magnitude hypothesispredicts that the same factors are implicated for women and men butdifferences occur in the strength of correlates.Alternatively, women may engage in sexual risk fordifferent reasons than do men, leading to adifference in pattern hypothesis. We compared these possibilitieswith a sample of 576 primarily White, middle-class,never-married college students, most of whom werebetween 17 and 25 years of age. Analyses of loveattitudes, risk perception, sensation seeking, and riskbehaviors in other domains in relation to sexual riskbehavior showed some gender similarities as well asdifferences. Findings were more consistent with the difference in pattern hypothesis than with thedifference in magnitude hypothesis. 相似文献

Emotional availability and attachment representations in kibbutz infants and their mothers. 总被引:1,自引:0,他引:1
Three components of the attachment transmission model were examined in 48 kibbutz dyads from 2 kibbutz sleeping arrangements: communal and home-based. Concurrent assessments used the Strange Situation procedure (M. D. Ainsworth, M. C. Blehar, E. Waters, & S. Wall, 1978) for infants' attachment relations, the Adult Attachment Interview (C. George, N. Kaplan, & M. Main, 1985) for mothers' attachment representations, and the Emotional Availability Scales (Z. Biringen, J. L. Robinson, & R. N. Emde, 1993) for emotional availability in the dyads. Security of infants' attachment relations as well as autonomy of mothers' attachment representations were associated with higher emotional availability scores. In addition, significantly poorer emotional availability was found in dyads in which infants were insecurely attached and mothers were nonautonomous. Results also indicate that in the ecology of collective sleeping, the associations between the experience of emotional availability in the dyads and infants' and mothers' attachment may have been disrupted. 相似文献

People often receive information about new immigrant groups prior to any direct contact with group members. However, it is not clear how this information shapes attitudes toward the groups. To explore this issue, 204 subjects were told about an unknown immigrant group that was presented as high or low in personal relevance. Subjects were then given positive or negative consensus information about the emotions that group members elicit from others, group members' personality traits, and group members' values. As expected, results indicated that the presentation of positive information about emotional reactions, personality traits, and values caused attitudes to be more favorable than did the presentation of negative information. Importantly, however, the combined impact of the emotion and personality trait information depended on whether the group was perceived to be of high or low personal relevance. Specifically, when the information about emotions and personality traits was similarly valanced (i.e., both were positive or both were negative), attitudes toward the group tended to be less favorable in the high personal relevance condition than in the low personal relevance condition. In contrast, when mixed information was presented (i.e., positive emotions and negative personality traits or negative emotions and positive personality traits), attitudes tended to be more favorable in the high personal relevance condition. In addition, attitudes, once formed, predicted further perceptions of the group and behavioral intentions toward group members. The implications of the findings for the reduction of prejudice toward new immigrant groups are discussed. 相似文献

This study sought to find out how much total knowledge adolescents had concerning AIDS, what particular areas of knowledge were deficient, and how those areas might be related to attitudes and experiences in their social world. Seventy-eight adolescent males from one suburban and three urban high schools were interviewed. A 101-item questionnaire was used to assess: a) overall knowledge about AIDS; b) attitudes about sexuality, drugs, death, and AIDS and; c) related aspects of their social world, i.e., number of IV drug users known, and sources of information about AIDS. Analyses of variance were performed on overall knowledge of AIDS and on five content areas of knowledge. Race was shown to relate to significant differences in the knowledge scores. The social world associated with the urban samples were discussed as risk factors for minority youth. Different attitudes related to strengths and weaknesses in different areas of knowledge. Attitudes associated with deficiencies in different subareas of knowledge were discussed as additional risk factors and as presenting target areas for AIDS education efforts. 相似文献

The authors investigated the combined effects of direct instruction and precision teaching by peer tutors in a high school driver education curriculum. Learners (N = 4) included students with intellectual and learning disabilities and students without disabilities. Peer tutoring was associated with immediate increases in correct responding and a simultaneous and rapid deceleration of errors. Three learners passed the written tests in the driver education classroom, obtained driver's licenses, and produced similar or better driving records than students who did not require assistance. This program is being continued and expanded by school personnel without assistance from the authors. 相似文献
