Seventy-three educationally handicapped (EH) and 78 regular class, normally achieving (NA) boys grades 3–8 were tested with a series of measures selected to test three components of attention: coming to attention, decision making, and maintaining attention over time. EH and NA samples were subdivided into three groups by grade level (grades 3–4, 5–6, and 7–8). Based on a teacher-completed behavioral check list, the EH group was further subdivided according to pupils perceived by teachers as hyperactive or nonhyperactive. With the exception of the youngest group, EH and NA samples did not differ from each other on CA, but regular class boys had slightly higher IQs and better reading scores than did their EH peers;EH hyperactives and EH nonhyperactives differed significantly on reading scores, the difference favoring the nonhyperactives. All pupils were individually administered the Children's Embedded Figures Test (CEFT), the Matching Familiar Figures Test (MFFT), and the Children's Checking Task (CCT), the last designed specifically to assess ability to maintain attention over time. EH pupils did not function as efficiently or as accurately on the attentional tasks as did their normally achieving age peers. Significant differences between EH and NA samples were found for CEFT and MFFT errors, as well as for CCT errors of omission and commission. Analyses of the EH group according to hyperactive-nonhyperactive status were for the most part nonsignificant. Correlational analyses yieMed low but statistically significant relationships among the attentional measures, but nonsignificant relationships between IQ and the attentional test scores. Findings were consistent with the interpretation that the three hypothesized components of attention are partially independent and thus may have differential influence on pupils' performance in school.This research was supported in part by U.S. Public Health Service Grant No. 1 RO 1 25076-01A1 and Contract No. 5893, between the State Department of Education and the University of California, Los Angeles.  相似文献

Following the spring 1970 confrontations between undergraduate college students and construction workers in lower Manhattan, a study of attitudes of a sample of undergraduates and construction workers was conducted. One hunderd Columbia University undergraduates and 100 apprentice construction workers were asked to indicate their level of agreement with 10 statements which were intended to embody "basic American tenets". The respondents within each group were also asked to predict the attitude that a member of the other group would hold. A "liberal/conservative" dichotomy was developed for the instrument by having independent judges categorize each of the 10 items as representing a "liberal" or a "conservative" attitude.
The expectations that student responses would be more liberal than construction worker responses and that each group would perceive this difference were tested and supported. The expectation that students perceive construction workers to be even more conservative than the workers report themselves to be was also supported. But the construction workers did not demonstrate the expected exaggeration of the students' liberalism.  相似文献

This paper introduces a technique applicable to the question: Does information in short-term memory disappear with time? The technique appears to eliminate Ss' rehearsal in the retention interval without introducing potentially interfering material. In the experiment, Ss read aloud three words, then engaged in a difficult auditory signal detection task intended to keep them from rehearsing for 15 sec, and then attempted to recall the three words. The results provide no support for the principle of loss with time as an explanation of forgetting in short-term memory.  相似文献

American society is analyzed as a gender-class system wherein tokenism is defined as a form of interclass mobility. Two role partners, Sponsor and Token, sustain the institution of tokenism: the Token is a member of the deviant class and the Sponsor is a member of the dominant class. The content and functioning of this role partnership are broadly defined. The limitations of tokenism and implications for change in the social system are discussed.  相似文献

The effects of shifts in the rate of presentation of repetitive neutral events (background event rate) were studied in a visual vigilance task. Four groups of subjects experienced either a high (21 events/min) or a low (6 events/min) event rate for 20 min and then experienced either the same or the alternate event rate for an additional 40 min. The temporal occurrence of critical target signals was identical for all groups, irrespective of event rate. The density of critical signals was 12 signals/20 min. By the end of the session, shifts in event rate were associated with changes in performance which resembled contrast effects found in other experimental situations in which shift paradigms were used. Relative to constant event rate control conditions, a shift from a low to a high event rate depressed the probability of signal detections, while a shift in the opposite direction enhanced the probability of signal detections.  相似文献

Wales and Grieve (1969) report an experiment in which they show that a factor of “confusability” affects the comprehension of affirmative and negative sentences, and then claim that this is a relevant factor in explaining the difficulty of negatives. The present paper submits arguments and experimental evidence to dispute this claim.  相似文献

This study examined the relationship between differences in current adjustment as they related to a number of demographic, personal, and situational factors for 65 late adolescents/young adults who had experienced this life transition. Utilizing multiple regression analyses, several factors emerged as particularly salient mediators of the adolescents' postdivorce adjustment, including distance from home, coping style, family cohesion, conflict and organization, and the use of family members for support. The importance of clarifying the role of psychological and situational mediating factors in order to understand the consequences of parental divorce and to organize preventive and ameliorative efforts for this population is discussed.  相似文献

This research investigated children's use of context to facilitate word recognition and comprehension-monitoring processes in the oral reading of connected prose as a function of grade level and decoding skill. Results indicated no overall contextual facilitation of word recognition accuracy, even in less skilled decoders, although there was evidence that less skilled decoders were assisted by context in decoding some content words. Children read word lists 50% more slowly than comparable selections of prose. The adoption of different and compensatory reading speed strategies in children's reading of prose and word lists renders the oral reading task an insensitive test of the contextual facilitation of word recognition accuracy. A qualitative analysis of the errors made in reading the prose passage showed that skilled decoders made (relative to less skilled decoders) a lower proportion of reading errors which, as first uttered, violated prior context, and a higher rate of contextually obligatory self-corrections, thus making a higher overall rate of contextually acceptable oral reading errors. These data were interpreted as suggesting that children's oral reading incorporates processing that occurs after lexical access, and that skilled decoders use context more effectively to monitor comprehension. In an oral reading task, this may counteract the tendency of less skilled decoders to rely more on context in the process of word recognition.  相似文献

Three experiments were designed to test the hypothesis that the structural processing of truncated passives is dependent upon the degree to which the past participle syntactically resembles an adjective. Two types of truncated passive were distinguished, one predicted to be processed according to the standard transformational account, and the other analogously to the predicate adjective construction. In sentence-completion tasks, both children and adults showed differential rates of agentive phrase recovery to the two types of truncated passive. A third experiment showed that the linguistic intuitions of adult subjects differed for the two types of truncated passive.  相似文献

This investigation assessed the hypothesis that girls are more likely to be learned helpless in math than boys. Students in grades 5 through 11 completed questionnaires assessing their causal attributions for success and failure in mathematics, their self-concepts of math ability, and their expectations for both current and future success in math. Results indicated that sex differences in attributions depended on the type of methodology used (open-ended or rank-ordered questions). The most consistent difference involved the differential use and ranking of ability, skills, and consistent effort. No sex differences were found in either students' perceptions of their own math ability or in their current achievement expectations. Girls, however, rated their future expectations slightly lower than did boys. Taken together, these results provide little support for the hypothesis that girls are generally more learned helpless in mathematics than are boys.  相似文献
