Fourth-, sixth-, and eighth-grade students were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Each category pair was either semantically similar or semantically dissimilar. The results indicated that even for the youngest children, similar categories required less search time than dissimilar categories. It was suggested that while dissimilar categories had to be accessed successively prior to search, subjects were able to consolidate similar categories into a superordinate group which eliminated the time to shift from one category to another during search. The results were contrasted with clustering studies which have demonstrated a minimal amount of memory facilitation in children for conceptually related items over unrelated items. 相似文献

Six-letter arrays containing symmetrical, e.g., H, M, T, or asymmetrical letters, e.g., J, K, R, were tachistoscopically exposed bilaterally for 100 msec. to 100 college students. Significantly more asymmetrical than symmetrical letters were identified, and significantly more Ss identified more asymmetrical than symmetrical items. This experiment, which incorporated methodological considerations suggested by Harcum (1964) and Bryden (1968), corroborates their findings. Their ideas and other findings were used to account for the data. Asymmetrical letters have more intrinsic left-to-right directionality than symmetrical elements. The rapidly fading after-stimulation of tachistoscopically presented alphabetical material is usually scanned from left to right. Individual array letters might also be scanned in the same direction. Confluence of directionality of letter and scan, which obtains only with asymmetrical letters, might have typically allowed asymmetrical targets to be scanned more rapidly and, consequently, more efficiently than symmetrical displays. 相似文献

Ninth graders rated their degree of liking for each of 12 striving tasks and, on another occasion, rated their perceptions of the similarity between each pair of tasks. Analyses of variance revealed strong PersonX Task interactions, suggesting the possibility of individual differences in task preference generality. A derived measure of task preference generality-specificity related significantly to an overall measure of perceived task similarity—generalizers saw the tasks as being more similar than did specifiers. Investigation of individual differences in degree of cross-situational generality was suggested as a way to integrate trait and situational theories of behavior.Data collection and initial data analyses for this study were conducted under the auspices of the Institute for Juvenile Research, Chicago, Illinois. Gratitude is expressed for the cooperation of the staffs and students at St. Michaels and Immaculata high schools, Chicago; for useful discussions of theoretical issues with Mark Oberlander; and for much assistance with data analysis provided by Arthur Kendall. 相似文献

A single-subject multiple-baseline design using within- and across-subject replication was employed to study the acquisition of expanded “agent-action-object” sentences and the spontaneous generation of this form in the natural environment. Three young language-delayed subjects were trained to describe various agent-action-object relationships with a five-element syntactical form. The language training strategy was a synthesis of the developmental-psycholinguistic and behavioral models. Dynamic interactions between familiar persons and objects were the stimulus events that the children mapped. A five-element syntactical form, previously absent from the children's language repertoires, was trained during individual sessions. Concurrent with baseline, training, and followup, each subject's language was monitored in another setting, the classroom during free play. After onset of training, the core elements of the complex syntactic form were spontaneously emitted by the child in its natural environment. The free-play data reflect individual differences in the emergence and frequency of each child's spontaneous use of the agent-action-object form. The acquisition and maintenance of the specific lexicon and syntax trained were tested by posttraining probes and responses to videotape presentations. These probes revealed generalization and maintenance of both the lexical and syntactical forms acquired in treatment. The main purpose of any language-training procedure should be to provide language that is functional for the child in the natural environment. This study, which documented the spontaneous usage of the core agent-action-object syntactical form in the natural environment, effectively trained a functional syntactical rule. 相似文献

Favorability of outcome and clarity of decision rule were manipulated in a simulated conflict resolved by an impartial third party. Overall, subjects who received favorable outcomes were more satisfied than were those who received unfavorable outcomes. In addition, favorability of verdict and clarity of decision rule interacted in affecting overall satisfaction. Among subjects receiving an unfavorable verdict, those whose outcomes had been determined by a defined decision rule experienced greater satisfaction than those whose outcomes were based on an unclear, undefined rule. However, given a favorable outcome, the effects of clarity of decision rule were reversed-subjects reported greater satisfaction with the undefined than the defined rule. These results are discussed with reference to the particularism/universalism of defined and undefined decision rules. 相似文献

This study investigated the effects of involving two sources of ‘non-traditional manpower’ — namely, university students and parents — in a programme of psycho-educational intervention. It was predicted that, while intervention for children with learning problems would produce significant changes in their perceptions in relation to their families, in their scholastic skills and in their adjustment, the additional involvement of their parents would lead to even greater changes. To test this prediction, 36 children referred to a university Education Clinic were randomly divided into three equal-sized groups: youth counselling plus parent counselling (E1), youth counselling (E2), and a control group (C). While the hypothesised changes following intervention were not statistically demonstrated, clinical data did yield support for the effectiveness and potential value of the intervention programmes. 相似文献

Children from Grades 2, 3, 5, and 7 (7.6, 9, 11, and 13 years of age, respectively) were required to generate or study exemplars of semantic categories (semantic orientation) or rhymes to stimulus words (phonetic orientation). Each child then participated in one of three retention tests: free recall, standard recognition, and rhyme recognition. The results indicated that the developmental emergence of the “generation effect” (C. E. McFarland, Jr., T. J. Frey, & D. D. Rhodes, Journal of Verbal Learning and Verbal Behavior, 1980, 19, 210–225; N. J. Slamecka & P. Graf, Journal of Experimental Psychology: Human Learning and Memory, 1978, 4, 592–604) was dependent on both encoding orientation and the type of retention task employed. A substantial generation effect first emerged (7-year-olds) for standard recognition in the semantic condition. A similar effect for recall was evident for 9-year olds, but not for younger children. Internal stimulus generation became a strong memory facilitator for phonetically encoded items at age 11 for standard recognition, but not until age 13 for recall. The results of the rhyme recognition test indicated that internal generation facilitated “transfer-appropriate processing” (C. D. Morris, J. D. Bransford, & J. J. Franks, Journal of Verbal Learning and Verbal Behavior, 1977, 16, 519–533) only for seventh graders (age 13). The processes underlying this developmental pattern were discussed. 相似文献
