Previous research suggests that young children do not attempt to represent depth relationships between objects in their drawings. The present study, however, showed that when both objects are visible and the children's attention is drawn to the depth relationship between them, most 5-, 6-, and 7-year-olds do attempt to portray this relationship.  相似文献

Attempts to represent the occlusion of a farther object by a nearer one are infrequent in the drawings of 5- and 6-year-olds. Instead they typically draw the objects side by side or one above the other. This does not appear to reflect a limitation of skill (P. Light & E. MacIntosh, Journal of Experimental Child Psychology, 1980, 30, 79–87) and it is hypothesized that it reflects the children's concern with the array of objects per se, as opposed to their own particular view of it. In the present study relatively complex objects were used in order to test the hypothesis that young children's drawings do in fact systematically reflect spatial relationships within the array. Ninety-seven children between 5 and 8 years of age drew two arrays, each being drawn four times in different orientations vis à vis the child. As predicted, the younger children's drawings contained much array-specific information but often no indication an all of the child's viewing position. In contrast, the older children's drawings were predominantly view specific, often containing little information about the arrays.  相似文献

Ninety-six children copied simple line drawings of perspective views of cubes and similar designs unlikely to be seen as representing objects. The views of cubes were copied much less accurately than the non-object patterns, and the errors made in copying the cubes involved replacement of properties specific to the single perspective view by properties more appropriate to the object itself. Some copies were drawn with the child continually looking at the model and unable to see his own copy, others were drawn in the normal way. Copies made in the former way were more accurate, but even under these conditions cubes were copied less accurately than the non-object patterns. The disadvantage of object pictures, as far as literal copying accuracy is concerned, was still present at 9 1/2 years of age, but was less than at 7 1/2. Two possible explanations are discussed. One is in terms of computational complexity, the other in terms of graphic motor schema. On the basis of the drawings obtained a few suggestions are made about the content and development of the data-structures for cubes.  相似文献

The “air gap” phenomenon was found to be very common in the free landscape drawings of middle and later childhood. Three experiments are reported in which the contextual cues for such drawings were systematically manipulated. When subjects were supplied with drawing sheets constructed to imply the absence of the air gap, the phenomenon was eliminated in most of their drawings. When supplied with sheets constructed to imply its presence, most subjects produced air gap drawings using contextually provided reference lines. There were no consistent transfer effects across different cuing orders. The susceptibility of the air gap phenomenon to modification by task manipulation suggests that it results from problems of production rather than from defects in the child's internal representation of the world.  相似文献

While the young child's difficulties in correctly comprehending the term less are well known, it appears less widely recognized that young children may also encounter difficulties with the term more. The present study shows that in a task which requires judgments about more to be based on the relative numerosity of sets, 3–4-year-old children may base their judgments on other parameters, such as the extent to which the sets are homogenous with respect to the color of their components. The implications of such findings are briefly considered.  相似文献

The present study was designed to determine when children first display evidence of hierarchical conceptual organization. Children aged 5 to 9 answered either semantic or sensory questions about a list of words composed of either superordinate terms, prototypical category instance, or moderately typical instances. In a later unanticipated cued recall task the children were given taxonomically related cues composed of the two remaining word types not used in the orienting phase. The 5-year-olds' performance revealed that they possessed a modest degree of hierarchically organized conceptual information, which by age 9 had developed to relatively sophisticated levels. In particular, it was found that the range of information contained in the 5-year-olds' conceptual hierarchies was considerably narrower than that of the 9-year-olds', which supports Rosch's contention that conceptual categories are first constructed around prototypical instances. The children's performance on the cued recall task was also compared to their performance on traditional class inclusion and object-sorting tasks. It was found that the object-sorting task overestimated, while the class inclusion task underestimated the extent to which conceptual information is hierarchically organized in 5-year-olds.  相似文献

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10-year olds and is shown to account for about two-thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed.  相似文献

The present study investigated the effects of review on young children's memory for prose. Prose passages were parsed into three levels of thematic importance. Five groups (128-year-old children each) participated in three experimental sessions, with each session separated by 1 week. During the first session all subjects listened to two passages. One week later, subjects in four of the groups received differing review experiences. During the third session, delayed retention was assessed. The data are interpreted to indicate that the repetition of the original learning experience was the most effective review; however, immediate reproduction following initial exposure also significantly attenuated forgetting. All groups favored the central passage ideas in their delayed recalls, regardless of their review treatment. The potential benefits of an immediate test as a review exercise was suggested.  相似文献

Various methods of social skills assessment with children were reviewed. Based upon an extensive review of the literature, it was found that behavioral observations, sociometrics, and teacher ratings have been the most often used methods of assessing children's social skill deficits. Advantages and disadvantages of each assessment technique were discussed within a psychometric and social validation context. Conclusions were that school psychologists should utilized all three measures to secure a comprehensive picture of children's social behavior and to obtain some measure of social validation.  相似文献

French children between 4 and 10 years old were asked to draw representations of French negative sentences. The results indicated that in most cases only the verb is negated when the noun phrase to the right of the negation is introduced by a definite article, but when the noun phrase is introduced by an indefinite article, it is most often the noun phrase itself that is negated. This effect is clear even in 4-year-olds, and it serves to demonstrate that the interpretation of negative sentences depends on phenomena of surface structure as well as of deep structure.  相似文献

Two experiments are reported that investigate the ability of 5 year olds to determine the reference of anaphoric pronouns. The first study shows that children have problems coping with more than one pronoun in a sentence and if they have to draw an inference to define the reference of a pronoun. The second study shows that the difficulty in assigning reference is not due to children merely forgetting the premise information but is due to the difficulty of carrying out the inference. There is an indication in the second study that some of the children may be using a syntactically oriented rule (that the pronoun should be assigned to a noun phrase that has a parallel function in the previous sentence), and that they are not drawing the appropriate inferences.  相似文献

According to previous research, young children do not understand displaced aggression. The present study examines the early phases of the understanding of the causes of moderately and extremely displaced aggression. Preschool and kindergarten children (3 to 5 years of age) viewed eight videotaped episodes of displaced aggression. Their comprehension of this aggression was assessed by means of open ended questions and forced choice picture selections. By age 5 most children had some understanding of displaced aggression, but this understanding was not complete. The early understanding revealed in the present study may be due to the use of short, simple realistic videotaped episodes appropriate for the limited processing abilities of young children. Extreme displacement was not more difficult to understand than moderate displacement.  相似文献

Kindergarten children (N = 70) learned to order 12 photographically presented objects. The objects were well known and either unrelated or categorizable into two, three, four, or six well-known categories. Free recall was assessed. Results indicated that the children used category membership both to learn and to recall the items. However, they processed the list composed of six pairs of items at least as efficiently as lists composed of fewer but larger groups of items (including a list indexed as easiest through previous adult performance).  相似文献

Three experiments are reported that explore 3-year-olds' and adults' understanding of the words, same and different. In the first, 3-year-olds selected a bead that was “the same color as” or “a different color from” a target bead. In the second, 3-year-olds selected a bead that was “the same in some way as” or “different in some way from” a target bead. Contrary to results reported previously, the majority of consistent responders chose a bead identical with the target in response to the different instruction in both experiments. The rates of both incorrect different responding and incorrect same responding were greater in Experiment II than in Experiment I. In Experiment III, adults chose objects that were “the same as” or “different from” a target; unlike the children, they never chose a target-identical object in response to different instructions. It is argued that children and adults treat same and different differently, and that children's task performance is influenced by three factors: semantic, pragmatic, and nonlinguistic.  相似文献

Sex prejudice in children's friendships has frequently been noted. This study examined the role of similarity of attitudes and personal construct ratings in this effect. Subjects were two classes of school children, aged 7–8 and 9–10 years. There were 29 children in each class. Subjects completed an attitude scale, construct rating scale, and sociometric questionnaire. Similarity effects were primarily in the younger children. Boys were more similar to each other in attitudes than were girls, and girls were more similar to each other in construct ratings than were boys (p < .001); there was greater similarity of attitudes and construct ratings in friendship rather than nonfriendship comparison dyads (p < .01). The sociometric data, when compared with sociometric data collected 6 months earlier, showed that these results could not be due to sex differences in the stability of friendships but rather suggested age and sex differences in the informational bases of friendships in middle childhood.  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

Four experiments investigated interference in 5-year-olds' learning sets. Experiment 1 manipulated intertrial and interproblem intervals, showing that increased intertrial intervals retarded performance. Long interproblem intervals interacted with short intertrial intervals to produce performance facilitation. Experiment 2 investigated interpolations within problems with either similar or dissimilar stimulus presentations. Similar stimuli caused greater performance decrements than dissimilar. Experiment 3 hypothesized that the within-subjects design of Experiment 1 masked interproblem interval effects. Testing between-subjects established that increased interproblem delays facilitate performance. In Experiment 4 interproblem delays were further tested in a series of shifts within and between dimensions. Increased delays more greatly benefited shifts within dimensions. It is concluded that intertrial and interproblem intervals affect learning set performance differentially. Intertrial delays result in performance deterioration due in part to interference. Interproblem delays facilitate performance at least in part by providing the opportunity for suppression of proactive interference, and perhaps in part by providing the opportunity for constructive cognitive processing.  相似文献

The effect of age-related differnces in the use of recall organization on the amount of recall and the properties of recall-acquisition patterns obtained in a multitrial part-whole transfer task was investigated among subjects in grade levels 1, 4, 7, and college (ages 6.5, 9.6, 12.6, and 19.7 years, respectively). Half of the subjects receiving relevant and irrelevant part lists sorted stimuli before recall trials; other subjects studied the items as they were presented, one at a time. Relevant part list learning was equally facilitative for all age groups regardless of presentation condition, and despite the greater amounts of recall organization found among college subjects. All age groups showed trial-to-trial improvements in whole-list recall; however, only the college subjects showed corresponding improvements in clustering, and all age groups had high rates of fluctuation in the composition of their recall from trial to trial. It was concluded that while even the limited amounts of spontaneous recall organization found among children are sufficient to enhance recall, organization is not a necessary condition for recall improvement and not the primary means by which children throughout the preformal-operations period increase their recall of unrelated stimuli over trials in a free-recall task.  相似文献

Sixty-seven elementary school students, ages 5 through 10 years, from three ethnic groups were systematically exposed, over a 1-month period, to specially produced television commercials. One treatment group viewed prevideotaped cartoons interspersed with commercials of women in “traditional” roles, while a second group viewed the same cartoons but with commercials which portrayed women in traditionally male or “reversed” roles. Children were measured on pre-and post-tests on (1) their occupational knowledge, (2) the extent to which they stereotyped occupations, and (3) their own preferences for traditionally male and female jobs. Results indicate that children do learn about occupations from television content, that they also learn to stereotype or nonstereotype various occupations based on the sex of the TV model, and, finally, that girls will change their preferences for various occupations based on the particular roles they view women portrayed in.  相似文献

Two experiments examined the effect of spacing repetitions within a word list on the free recall performance of elementary school children. In the first experiment, spacing repetitions facilitated recall, and the function relating recall of repeated items to the spacing between repetitions was the same throughout the age range investigated (first, third, and sixth graders). But, the function for these elementary school children reached asymptote at a much shorter spacing than the function typically reported for adults. The second experiment was designed to test an encoding variability explanation of spaced-repetition effects in elementary school children. Results for both third- and sixth-grade children were consistent with the hypothesis that differential encoding of repetitions facilitates performance and that spaced repetitions are remembered better because they are more likely to be differentially encoded. A theoretical framework was discussed that may be able to encompass both these results and another finding in the literature which indicates that differential encoding can sometimes impair rather than facilitate children's memory performance.  相似文献
