Coordination and integration of class information was examined using a multidimensional similarity judgment task in which four- and nine-year old children rated the similarity of pairs of stimuli sharing either one or two atribute values. Half the children at each age were assigned to an attention condition requiring they label relevant stimulus atributes before making their similarity ratings. The other children were in the nonattention condition, and rated similarity without labelling the attributes. The results indicated that four-year-olds in the attention condition and nine-year-olds in both conditions integrated class information in making their similarity judgments. Performance of the four-year-olds in the non-attention condition tended to improve across trials; they appeared to integrate class information on later trials. 相似文献

Humphreys's test of Spearman's hypothesis (viz., that the size of the standardized black-white differences on various psychometric tests is positively related to the tests' loadings on g, the general intelligence factor) is methodologically weak. It is based on comparison of a fairly representative sample of the black population of U.S. school children with a highly selected sample of the white school population, representing the lowest 15 to 20% of whites in socio-economic status (SES). A fair test of the hypothesis requires that the black and white samples should not be selected on any g-correlated variable, such as SES. Selection attenuates and distorts the relationship between tests' g loadings and the magnitude of the standardized mean black-white differences on the tests. Other unorthodox conditions in Humphreys's study, such as performing factor analysis on the test-score means of various arbitrary demographic groups instead of on individual test scores inflates tests' g loadings and biases the test of Spearman's hypothesis by restriction of reliable variance in g loadings. Humphreys's study cannot be considered a proper replication of Jensen's examination of Spearman's hypothesis in 11 different studies comprising 74 different tests, which consistently bears out Spearman's hypothesis. 相似文献

The potential of Holland's theory for use in the vocational guidance of adult women depends in part on more validity data with regard to the conceptual meaningfulness of the constructs. This study reports the findings of a correlative analysis between scores on Holland's Vocational Preference Inventory (VPI), which measures the six “styles”, and selected scales on four criterion tests predicted in advance to be related to the VPI. The findings for this sample of adult women indicate strong evidence for the validity of the Intellectual, Conventional and Enterprising “styles”, but questions are raised with regard to the meaningfulness of the Realistic, Social, and Artistic types. 相似文献

The operation of a “speaker-state signal” in two-person, face-to-face conversations is hypothesized. Display of this signal by an auditor appears to indicate, among other things, that he is claiming the speaking turn, differentiating this action from a “back-channel behavior” by which he merely acknowledges some portion of the speaker's message. The signal also appears to play a part in the resolution of situations in which both participants simultaneously claim the speaking turn. The signal is defined as the display of at least one of a set of four behavioral cues, two in paralanguage and two in body motion. 相似文献

In response to the critique of Gaes, Quigley-Fernandez, and Tedeschi (Journal of Research in Personality, 1978, 12, 189–192) it was acknowledged that the cell Ns were incorrect as originally reported, and the weakness of a postexperimental division of subjects was reaffirmed. Emphasis was placed on the comparability of a simple rating scale and an elaborate bogus pipeline in measuring attraction. The need for determining the way in which the bogus pipeline functions prior to its uncritical adoption in any given experimental situation was stressed as a point of agreement. 相似文献

Kindergarteners and third graders were given a continuous recognition memory task involving two-digit numbers. In addition, a rating scale consisting of photographs of various facial expressions was used to obtain confidence judgments from the Ss. Conventional analyses as well as signal detection analyses of the data revealed the following results: (a) the overall performance of the third graders was superior to that of the kindergarteners; (b) memory strength decreased as the number of intervening items increased; (c) there was no difference in the forgetting rates of the two grade levels; (d) the third graders exhibited a more liberal response bias than the kindergarteners; (e) both the hit rate (probability of correctly labeling an old stimulus as old) and the false-alarm rate (probability of incorrectly labeling a new stimulus as old) increased across blocks of items; (f) the increases in the hit rate and the false-alarm rate over blocks were due to a change in criterion from a relatively conservative level to a more lenient one; (g) the lower the S's level of confidence in judging an item as old, the lower was the probability of that item actually being old; (h) the third graders were better than the kindergarteners at gauging the accuracy of their recognition responses. It was concluded that with respect to recognition memory, chidren as young as years old are capable, to some extent, of monitoring their own memory states. 相似文献

Recent research has established decision making as an important type of strategic problem solving. From this perspective, the present paper examines strategic decision behavior in children and, in particular, the ability to adapt decision strategies to task characteristics. Twelve-year-olds' strategies were identified through analyses of information search patterns with different-sized matrices of information. Using a similar procedure, Payne (1976, Organizational Behavior and Human Performance, 16, 366–387) found that adults shifted to more efficient (but less “optimal”) strategies as task complexity increased. The present study indicates that, by 12 years of age, children understand many of the basic concepts of strategic decision making, such as compensation and elimination, and, like adults, they modify their strategies appropriately in response to complexity. However, their behavior differs from that reported for adults in that the distinctions among specific decision strategies are not clear cut, and there is frequent use of less demanding, cost-cutting strategies even with smaller decision tasks. Memory capacity and topic interest also affect decision strategy. The results support the feasibility of further developmental study of decision strategies. Analytical techniques developed here for use with children may profitably be applied in studies with adults as well. 相似文献

Twelve children, 21–34 months old, six in R. Brown's Stage I and six in Stages II and III, responded to commands varying in length, grammaticality, and meaning. All of the children responded significantly less often when the commands were situationally anomalous and/or ungrammatical. Results failed to replicate the results of E. Shipley, E. Smith, and L. Gleitman (Language, 1969, 44, 332–342) and J. Wetstone and B. Friedlander (Child Development, 1973, 44, 743–750). The results also suggest that young children rely heavily upon situational cues in their earliest comprehension of adult speech, and this supports arguments made by J. Strohner and K. Nelson (Child Development, 45, 567–576) and R. Chapman and J. Miller (Journal of Speech and Hearing, 1975, 18, 355–371). Since subjects rely upon nonlinguistic cues to respond appropriately, syntactic competence cannot be inferred from apparent comprehension. 相似文献

The effects of perceptual set and of “sequential visual noise” on the identification of briefly exposed pictures were examined in 5-year-olds, 8-year-olds, and adults. Subjects were asked to indicate whether a brief target matched a standard. The standard picture was presented either before the target picture (to establish a set) or after the target. The target was presented either alone or last in a series of six brief pictures (i.e., in noise). Adults and 8-year-olds were at ceiling when the target was presented alone, but set facilitated their identification of the target in noise. The 5-year-olds benefited from set both when the target was presented alone and when it was presented in noise. These findings suggest that set for a specific target picture functions similarly at all ages. 相似文献

Previous research has examined the characteristic errors made by young children when drawing from a three-dimensional array. The aim of the present research was to investigate the influence of context in copying tasks. In a series of three experiments children between the ages of 4 and 7 years were presented with contrasting models to copy. These included cups and sugar bowls in various combinations and orientations. In each experiment the children's copies were scored for inclusion or omission of the occluded handle on the model. The results showed that nearly one third of the children did not respond consistently by either copying accurately or by always including the occluded handle. Instead the findings pointed to a large group of children whose responses were directed by the type of context present within the arrays. 相似文献

This study explored characteristics of attributions made to negative outcome stories by fourth-, sixth-, and eighth-graders as well as college students. All subjects read six stories representing three stories for each of two levels (self-focus and behavior-focus) of a within-subjects factor, Focus of Attention. Dependent measures included both spontaneous attributions and structured evaluations on the dimensions of causality, responsibility, blame, and deservingness. Analyses of the spontaneous attributions indicated that Self attributions were more frequently given than either Behavior or External attributions to both self- and behavior-focus stories. The experimental manipulation of internal focus produced matching attributions only in the self manipulation. Analyses of the structured evaluations indicated that subjects used Cause and Responsibility interchangeably but only eighth-graders and college students differentiated Cause/Responsibility from both Blame and Deservingness. Cause/Responsibility was also shown to have more salience in the behavior-than self-focus stories. It is suggested that a verbal focus on behavior has limited effects in producing defensive, self-distanced attributions but may heighten evaluations of Cause/Responsibility. In addition, behavior-focus seems to have little effect on the development of the psychologically more complex evaluations of blame and deservingness. 相似文献

Four tasks were given to children from 4–12 to test their comprehension of complex sentences containing main verbs taking underlying sentences as their complements (Sally knew that she was early). In an imperatives task, very young children interpreted only the complement verb and ignored the complex verb. In a short-term memory task, sentences with two negations usually lost the second not in recall. In direct questioning and anomaly-detection tasks, children tended to make pragmatic inferences and excessively depend on knowledge about the world, as opposed to linguistic information. Overall results showed that even sixth graders had not yet attained adult-level comprehension of complex sentences. 相似文献

The study examined the suitability of Furth's nonverbal conservation test as a psychometric tool for measuring individual differences in Zambia. The subjects included normal and mentally deficient Zambian children aged 7–13 years. The test was validated against age differentiation, differentiation of different intellectual levels, and school performance. The results showed that scores on the test increased significantly with increase in age, correlated positively and significantly with school scores, and differentiated normal from mentally deficient children. Within the normal sample the test also differentiated dull from average children; within the deficient sample the test did not differentiate the moderately mentally deficient from the severely mentally deficient. These results are explained by reference to the characteristics of the test, performance on which requires learning, memory, and perceptual abilities. 相似文献

Female Ss' choices in two types of mixed-motive game situations were used to select Ss who had predominantly Own Gain and Ss who had predominantly Relative Gain goals. On the basis of simple reward notions, it was predicted that the former but not the latter would change from competitive to cooperative responding in decomposed Prisoner's Dilemma game situations when interacting with a conditionally cooperative other. Corresponding yoked controls were not expected to become cooperative. The availability of social comparison with an outcome which was smaller than the mutually cooperative outcome but larger than the mutually competitive out-come was expected to lead Own Gain Ss to more rapid learning of cooperation but not to affect the responses of corresponding yoked controls or of Relative Gain Ss. A 2 × 2 × 2 × 5 factorial design was used in which the factors were goal orientation (Own Gain vs Relative Gain), strategy of the other (conditionally cooperative vs yoked control), the availability vs unavailability of the social comparison, and trials. The results strongly supported each of the expectations. The results were discussed in terms of how the operation of the reward mechanism would be affected by the operation of some other social psychological processes. 相似文献

Three experiments examined young children's ability to evaluate the relationship between concepts as one of inclusion. In Experiment 1, the same group of 4-to 7-year-old children were given three tasks: one in which they made judgments about whether “all” or “some” members of a category were included in another category, and two tasks in which they made inferences based on knowledge of inclusion relations. The majority of children succeeded on at least one of the tasks, thereby implying that they could evaluate inclusion relations. Two further experiments provided more evidence for this hypothesis: Experiment 2 confirmed that nursery children could answer quantitative questions about conceptual interrelationts; Experiment 3 demonstrated that nursery schoolers could solve certain inference problems involving the construction and evaluation of hierarchies. 相似文献

Hunt envisions the automation of intelligence testing (Intelligence, 1982, 6, 231–240), but he appears to be overly optimistic. He neglects to mention conceptual and practical difficulties at the interface of measurement and theory that place psychometry not in the dawn of microcomputerization, but rather more nearly in its primordium. 相似文献

Mismatching in negotiation involves responding with high demands to the opponent's low demands and with low demands to the opponent's high demands. Prior research has shown that the opponent's demands are often mismatched but that this effect is attenuated when information is available about the outcomes achieved by the opponent from the available alternatives. The present research showed that mismatching was also attenuated when the negotiator knew the location of the opponent's limit (the alternative beyond which the opponent would not concede). Two new interpretations of the attenuation effect were suggested on the basis of this finding. In addition, women were found to engage in more mismatching than men, being particularly likely to exploit a soft opponent. 相似文献

To investigate developmental differences in time-sharing performance, 60 boys, 20 in each of three age groups (7-, 10-, and 13-year-olds) performed an auditory matching task and a tracking task alone and concurrently, the latter under two sets of instructions. Decrements produced by concurrent performance were compared for the three age groups. When the time-shared tasks were presented as equally important, time-sharing produced significantly greater proportional decrements in the tracking performance of the younger children and for all age groups tracking task decrements were directly related to matching task difficulty. Subsequently, the children were instructed that one or the other of the tasks was more important and that they were to improve their performance on that task. All three age groups showed a significant improvement on the task emphasized by instructions. The relationship of the results to two models of information processing is discussed. 相似文献

A new method is introduced for assessing children's component selection—i.e., the disposition to attend to a single feature of multifaceted stimuli. Eight-year-old children were found to exercise component selection to a lesser degree than 4-year-olds; while children at both age levels attended primarily to one stimulus component (shape), the older children showed a moderate amount of attention to a secondary redundant feature (color) as well. However, a comparable age difference in attention deployment was not observed when a single stimulus dimension (shape) was “relevant” in two variant tasks. These results imply a developmentally increasing ability to distinguish between conditions in which attending to redundant stimulus information can and cannot be useful. That this ability undergoes little further development beyond age 8 was suggested in a second experiment with 8- and 12-year-olds in which the three tasks produced relatively similar developmental trends in performance. 相似文献
