Native Israeli readers read Hebrew and English text as their eye movements were monitored. A window of text moved in synchrony with their eye movements and the window was either symmetrical about the fixation point or offset to the left or right. When subjects were reading Hebrew, the perceptual span was asymmetric to the left and when they were reading English it was asymmetric to the right. The results point out the importance of attentional factors in reading.  相似文献

From a school population of normal children third through fifth grades), thirty children initially identified as “angry”were randomly assigned to either an affective imagery training group, an attention group, or a control group. The treatment group received three sessions of affective imagery in which they focused on physiological changes and on their thoughts associated with prior emotional experiences. Teachers recorded pre-, post- , and short term follow-up aggressive behaviors for all thirty children. Cognitive perceptions and attributions were recorded at the same three occasions on the Affect Questionnaire. Results suggested that, as a result of affective imagery training, angry children's perceptions and cognitions shifted from “angry” towards “sad,” and there was a concomitant decrease in observed aggressive classroom behavior.  相似文献

Forty-four juvenile rhesus, 30 stumptailed, and 6 pigtailed monkeys were tested individually and in stable quadrads for time to contact slightly and highly novel objects. When peer-group tested, dominant monkeys were the first to contact the slightly novel but not the highly novel objects, unlike preferences found when they were tested individually. A role analysis revealed better contact-order prediction, most groups having their habitual first contactor. When this contactor was overtly punished or covertly trained to avoid the object, group response was altered. The use of the termrole is discussed in detail, concluding that a role involves a particular individual who is expected to interact with others while in certain groups to complete some beneficial function.  相似文献

It is shown that lexical decision times to strong associates with an associative strength of approximately 40% are facilitated relative to targets following a neutral prime, “blank,” whereas very weak associates with an associative strength of less then 3% are neither facilitated nor inhibited. It is also shown that relative to the “blank” baseline time, a row of crosses inhibits processing of the following target. The latter finding has implications for earlier studies that have used crosses as a neutral prime. In these studies, facilitation effects have been overestimated and inhibition effects have been underestimated. Neely 1976 has proposed a predict-and-match strategy according to which subjects are assumed to predict one or more targets from the prime and to match the actual target onto the predicted targets. A part of this theory is not supported by the present data. The results are discussed in terms of the two-process theory of expectancy (Posner & Snyder, 1975). They are also considered in the light of a recent theory by Becker (1980). As an alternative interpretation of part of the reported data, a coherence assumption by the subjects about all reading materials is introduced.  相似文献

A growing body of research suggests that low Mental Age (MA) autistic and retarded children show a unique stimulus control deficit, one that may cause many or most of their behavioral deficiencies. This problem, stimulus overselectivity, is evidenced when a child responds only to a restricted portion of the stimulus environment when compared with normal children. The purpose of this study was to assess whether this overselectivity is general across situations or whether it is restricted to certain stimulus/task conditions. Eight autistic children, who evidenced overselectivity on a preassessment task, and 8 normal children with similar MA levels participated. All children were trained on 3 tasks to determine if overselectivity varied as a function of different stimulus conditions. Each of the 3 tasks involved training a child to respond to (i.e., touch) a card containing a circle (S +) and to avoid a blank (S ?) card. In each case, the circle comprised a series of dots. The difference between the 3 circles (tasks) was the distance between the successive dots making up each circle. Also, in the minimal separation condition the dots were smaller in size and greater in number than in the larger separation conditions. Of concern was whether autistic children learned about the gestalt (i.e., the circle), which required attention to multiple cues, or whether children would overselect and respond to the dots. The results showed that (1) stimulus overselectivity was found not to be a generalized deficit in autistic subjects; instead, it varied as a function of the stimulus variables; and (2) the stimulus variables manipulated in this study similarly influenced the responding of both normal and autistic children. The implications of these data for a theory of overselectivity are discussed.  相似文献

As additional studies of assessment of analyzability have been reported, research has proven very difficult and provided little clarification. This paper reviews the literature, particularly of the last twenty-five years, from the viewpoint of identifying the nature of the problems in developing useful methods of study. Some approaches to these problems, which might provide increased understanding as well as a clearer definition of some inherent limitations, are discussed.  相似文献

Objective tests of personality typically include a number of items or trials; the total score on the test is the sum of the subject's “correct” responses across all such trials. Normally, the trials are varied systematically across various facets of the test design, so that the total score represents a composite measure of accuracy averaged across these test facets. However, since only one score is computed for each subject, some potentially important kinds of individual differences—namely all those associated with each particular variation in the test design—are treated solely as measurement unreliability. Such a psychometric stance may serve to obscure more differentiated types of individual differences, with the result that composite scores from trials based on one type of experimental design may not be highly related to such scores from trials using a somewhat different design. The present paper presents a general procedure for scoring objective tests more analytically. To illustrate this general rationale, and to demonstrate its potential utility, data have been reanalyzed from two previous studies, one using the Rod-and-Frame test, the other the Müller-Lyer illusion. In both cases, the traditional global accuracy score did not correlate significantly with other theoretically related variables, while a number of component scores were quite highly related.  相似文献

Summary Following an abrupt shift from a therapeutic community with emphasis on group meetings to a hierarchical medical model on a mental hospital floor, disturbed patients required extensive individual nursing care. This increased work load for the nursing staff resulted in admissions having to be limited to the rare cases who needed little or no nursing care. As patients were discharged, the vacancy rate went up to approximately 20% for a week and remained high for another two weeks. Nursing staff-patient relations deteriorated.Subsequently, it was possible to resume the emphasis on the groups of a therapeutic community and to observe the contrast. The experience showed how groups can effect and support a therapeutic community. It clarified some of the mechanisms by which groups positively affected disturbed patients. Some mechanisms by which the staff, community, and group meetings favorably influenced the nursing staff-patient relationship and intrastaff communications became clear also.  相似文献

Squirrel monkeys operated a key under second-order schedules in which every tenth completion of a 5-minute fixed interval resulted in either presentation of food or intravenous injection of cocaine. When a 2-second light was presented at the completion of the component fixed-interval schedules, positively accelerated responding developed and was maintained in each component. Over a tenfold range of doses of cocaine(30 to 300 microgram/kg/injection) and amounts of food (0.75 to 7.5 g/presentation); the second-order schedule of cocaine injection maintained higher average rates of responding than the second-order schedule of food presentation. Substituting saline for cocaine or eliminating food presentation decreased average rates of responding. When no stimulus change occurred at the completion of the first nine component fixed-interval schedules, but the 2-second light and food presentation or cocaine injection still occurred after the tenth component, only low and relatively constant rates of responding were maintained in each component. Patterns of responding characteristic of 5-minute fixed-interval schedules were maintained by the 2-second light paired with either cocaine injection or food presentation, though the maximum frequency of cocaine injection or food presentation was less than once per 50 minutes.  相似文献

Summary: A systematic psychodynamic approach to personality appraisal using the Strong Vocational Interest Blank is presented. The psychoanalytic concepts of transformation of infantile impulses, ego style, and structural self-representation are discussed in relation to issues of vocational choice. A method for making psychodynamic inferences from the SVIB is then put forth. To illustrate the method, &blind& personality evaluations, of three late adolescents, using only their SVIB profiles, are presented. The results of each appraisal are discussed in relation to independent information about the client and the counseling process.  相似文献
