A basic assumption in an interactional model of behavior is that individual behavior is more similar across situations which are perceived and interpreted as similar by the individual than across situations which are perceived as less similar or not similar at all. This proposition was investigated using a psychophysical scaling method for the study of perceived similarity between situations and measures of similarity between reaction profiles as expressions of cross-situational similarity in reactions. Individual data from 39 adolescents were analyzed. Hypothetical anxiety-evoking situations, and self-reported anxiety reactions, were used. The overall outcome of the comparison was in the predicted direction. For about 77% of the subjects the relationship was in the expected direction and for about 40% the relationship was statistically significant.  相似文献

A causal model for career choice was outlined, encompassing psychological cost-benefit-profit as a central intervening construct. The model was applied to the career choice (education vs work) after high school graduation and tested on longitudinal data from 173 students. The main problem concerned the relationship among the components in the causal career choice model, using multiple correlation and path analysis as tools. The results showed clear sex differences. For boys, the model was a rather powerful predictor of career choice (R = 0.70), and Psychological profit with regard to continued education had a clear direct effect as well as an indirect effect on career choice. For girls, the predictive validity was low (R = 0.35) and Psychological profit affected career choice only indirectly via Educational aspiration.  相似文献

Forty-six subjects were assigned to two groups according to a reaction time technique: one monolingual group of 14 subjects with German as the dominant language and one group of 32 German-Swedish bilingual subjects balanced in skills. The subjects were given short-term memory tasks on numbers presented aurally and a visually presented prose text involving both short-term and long-term memory processes. The results provide evidence that two language systems actively used in daily communication affect both speed and memory span for digits: when compared with monolingual subjects, balanced bilinguals read more slowly and showed a higher error rate in the recall of two-digit numbers. The results support a hypothesis of interdependent bilingual storage.  相似文献

Conceptual system as a cognitive-developmental variable in personality has been assumed to relate to different cognitions of self and others and of interpersonal relations at each developmental stage. The assumed relationship between conceptual system and some personality variables was studied in a group of students (N = 85). The “This-I-Believe” test (TIB) [Harvey, O. J. System structure, adaptability and creativity. In O. J. Harvey (Ed.), Experience, structure, and adaptability. New York: Springer, 1966.] for assessing the developmental stage of the conceptual system was administered together with personality scales for traits assumed important in socialization. A modified TIB scoring procedure was used. Highly significant differences in personality were obtained by a MANOVA, using conceptual system for classification. One dimension accounted for discrimination. Measures assumed to relate to sensitivity for and conformity to a social environment contributed most to the discrimination.  相似文献

In a reviewed series of spontaneous and learning-set studies of adults and children, we have monitored active-touch overt attending during concept learning. Adults solved the problems even if they attended to four dimensions in the same trial; however, young children failed when attending so broadly but solved when attending to a single dimension. In the present training study, 18 6-year-olds solved all problems when restricted to attend to anly one dimension. After a special pretraining program proceeding through the subprocesses of stimulus familiarization, discrimination, labeling, “attentional broadening,” and memorization, 13 of the children managed to attend to all four dimensions in one trial and solve faster than adults. Findings suggest a developmental hypothesis that learning grows with spontaneous “tailoring” of attention to memory capacity.  相似文献

‘Arousability’, as defined through spontaneous electrodermal responses, has been empirically linked to anxiety, phobic symptoms and outcome of systematic desensitization. Previous data from our laboratory indicate that ‘preparedness’, as defined through potentially phobic vs. fear-irrelevant or ‘neutral’ conditioned stimuh, is an important determinant of electrodermal conditioning. The present experiment compared groups selected to be high or low in spontaneous responding during differential conditioning to potentially phobic or neutral stimuh. It was found that the effects of these two factors were essentially additive, i.e. conditioning and resistance to extinction were better for phobic stimuli and for high-arousal groups. The high-aroused group with phobic stimuh showed diffuse responding during acquisition, not differentiating between reinforced and unreinforced cues. However, it was the only group that failed to extinguish during 20 trials, which indicates that high arousal gives superior resistance to extinction particularly for phobic stimuli.  相似文献

To what degree do infants use a predictive strategy when reaching for moving objects? This question was studied longitudinally in five infants from 18 to 36 weeks of age. The aiming of 356 reaches were analyzed by a technique that took into consideration the three-dimensional properties of the reaches. Each reach was divided into ballistic steps and the aiming of each step was calculated and compared with an optimal value. It was found that the infants studied had an ability to reach for fast moving objects in a predictive way. Further, the results show that the predictive ability is remarkably good in the lowest age groups which suggests that it is, at least partly, prewired. What develops seems mainly to be the mobility aspects of reaching which makes for more economical and flexible reaching. Older infants reach successfully for the fast moving object also with a nonpredictive chasing strategy.  相似文献

Subjects judged the cumulated risk of dying during a year for a set of persons or cases each characterized by the risks during three different periods of risk exposure during the year (e.g., 18 weeks with 2.3 deaths per thousand persons per year of exposure, 28 weeks with 2.5 deaths and 6 weeks with 16.0 deaths per thousand per year). Three main strategies were used for solving the problems: (1) addition of the risk levels, (2) computing the mean of the risk levels, and (3) the most frequently used anchoring and adjustment strategy most closely approximating the normatively correct risk over the year. The first two strategies do not use all relevant information because they neglect the importance of different exposure times. The anchoring and adjustment strategy used all information and was executed in a first stage in which an initial anchor or reference risk was selected followed by a second stage in which this anchor was adjusted according to the remaining information. The process for finding the first anchor was quite flexible, using different principles (e.g., extreme values or similarity) depending on the pattern of cues characterizing each case. Biases in relation to normative theory originated from subjects misunderstanding or simplifying the problem (Strategies (1) and (2)) or the characteristics of the anchoring and adjustment process which resulted in relative overestimation of short-time, high-risk cases. A few subjects, however, all of whom used sequential anchoring and adjustment, succeeded in giving quite accurate estimates.  相似文献

The present paper is intended to discuss critically the integration model of the functional interhemispheric relation that has become dominant in neuropsychology with the development, in the last two decades, of split-brain studies.While the split-brain research has undoubtedly produced new experimental methodologies, the current theorizing in this area has been contrastingly conservative. The present paper examines some of its basic assumptions, in particular that the corpus callosum is an association pathway devoted to interhemispheric transmission of information, and that the disconnected cerebral hemispheres function in a parallel way. It is shown that these assumptions have only low consistency both with split-brain behavior and with the normal organization of the fore-brain connectivity.In the early seventies, theoretical novelty has emerged from another research field with Kinsbourne's interpretation of laterality effects in normal man. His concept of asymmetrical hemispheric arousal is shown to be supported, with some reservations, by evidence in this field. But this dynamical concept has a more general value and there are signs that current ideas about the functional relation between the cerebral hemispheres are presently deeply transformed.  相似文献

How infants come to master reaching for moving objects was studied in a situation where the distance to and the velocity of the moving object varied. Eleven infants participated in the study. They were from 12 to 24 weeks old at the first session, were seen at 3-week intervals until 30 weeks old, and were finally seen once at 36 weeks old. The following behaviors were observed from video recordings: frequency of fixated and followed motions, latency to first goal-directed behavior, type of goal-directed behaviors, and type of reaches. It was found that by the time the infant masters reaching for stationary objects he will also successfully reach for moving ones. Eighteen-week-old infants caught the object as it moved at 30 cm/sec. The results suggest a basic human capacity to time-coordinate one's behavior with external events, and to foresee in one's actions future positions of moving objects.  相似文献

Previous research has shown that intermittent punishment of a response increases its persistence to continuous punishment and that intermittent punishment training in one situation produces persistence to continuous punishment in other situations. Experiment 1 showed that as long as the instrumental response and punishing stimulus were held constant from intermittent to continuous punishment marked differences between these situations had no decremental effect on persistence. Experiment 2 showed that intermittent punishment training of one response resulted in substantial persistence to continuous punishment of a different and apparently incompatible response and that such response change had no more than a marginal effect on persistence. The results were seen as requiring some revision to the traditional conditioning-model interpretation of persistence to punishment.  相似文献

The generality of the recognition failure phenomenon was the primary basis for the present research. It was hypothesized that the phenomenon obtains whenever an insufficient degree of compatibility exists between the task demands at recognition and those present during study. Experiments 1 and 2 demonstrated that, despite a recognition task that was incompatible to conditions of encoding, subjects could actively reconstruct aspects of the initial situation, and hence recognition failure was minimized. It was assumed that the stimulus material — categorized word pairs — facilitated this reconstructive process. Experiment 3 was designed specifically to examine further the reconstructive process as well as recognition failure. The results indicated that (a) the nature of this process could be mathematically predicted, and (b) subjects seldom failed to recognize words they recalled. The results of the present study strongly suggest an important boundary condition of the phenomenon of recognition failure. Moreover, Tulving and Wiseman's (1975) quadratic function could not predict accurately the obtained magnitude of recognition failure.  相似文献

Different forms of memory defects were studied in 16 patients with organic dementia. The test performance was related to the regional cerebral blood flow (rCBF) in the left (dominant) hemisphere. Verbal memory (Paired Associates) correlated to the blood flow in temporal and parietal regions. Spatial recognition (Memory for Objects, Memory for Geometrical Design) correlated to the temporal and lower frontal regions. One spatial memory test (Visual Retention test) correlated to the temporal region only. Another spatial memory test (Memory for Design) did not show correlations to any regions of the dominant hemisphere. Finally it was found that the hemisphere mean flow values did not correlate to performance. This emphasizes the main finding—the regional correlations. It is concluded that memory performance involves various extratemporal regions depending upon the specific quality of the memory task to be performed.  相似文献

The synthesis model, designed to explain effects of modality specific information on retention, is presented and tested. The model encompasses qualitative and quantitative components. The qualitative characteristics reflect the physiological properties of the auditory and visual channels. Three parameters are assumed to affect the quantitative efficiency of the channels. Each channel is assumed to have a certain capacity, and processing of information in the channels is determined by situational demands. Furthermore, processing in a channel is regarded as superficial. Increased allocation of processing to the superficial level was manipulated by the use of modality specific distractors and conditions of ‘supracapacity load’. Transformation of information from the visual to the auditory channel was controlled by the use of one mixed-mode and one single-mode experiment. Thirty subjects participated in the mixed-mode experiment and 60 in the single-mode experiment. Both experiments employed an identical distraction task, intervening presentation and free recall of the to-be-remembered items. The results confirmed the predictions of (a) modality specific distraction, (b) supracapacity performance decrement, (c) a larger distraction effect for the auditory channel and (d) transformation effects in the single-mode experiment.  相似文献

The existence of two different approaches to the theoretical understanding of social behavior is noted. The author presents a systems model as offered by Talavage and compares it with Rotter's social learning theory. The efficacy of the systems translation of Rotter's theory for the understanding of simple behavioral responses is discussed and a sample methodology incorporating systems theoretical implications is proposed.  相似文献

Two studies examined situational determinants of choice among anagram tests that varied both in difficulty and in diagnosticity (the information they provided about one's own ability). In both studies, subjects worked on a preliminary anagram test before making their choices. Study 1 manipulated level of performance on the preliminary test. Results showed that high performance led to preferring more difficult and more diagnostic tests. In Study 2, subjects were either paid or not paid for their performance on the preliminary test. Results showed that pay led to a preference for more diagnostic tests. Unexpectedly, results of both studies showed that although difficulty and diagnosticity were defined independently of one another, they were not perceived as such. Thus, high diagnostic tests were perceived as more difficult; more difficult tests were perceived as more diagnostic; and the difference between high and low diagnostic tests in perceived diagnosticity and choice of items (high diagnostic tests had higher scores on both measures) were more pronounced among more difficult tests. Motivational as well as cognitive interpretations of the results were discussed.  相似文献
