A group of 15 fourth-graders were given training on the transverse patterning problem, a task consisting of three different geometric forms presented in pairs. Three other groups of 15 fourth-graders each received training on problems containing the same geometric forms, along with either one (color or size) or two (color and size) additional nonspatial dimensions varying among the settings comprising the different cue-cue patterns. Contrary to a prediction derived from Croll's (1967) extension of Spiker's (1963) theory of discrimination learning, none of the Ss solved the basic transverse patterning problem, nor was there any improvement in performance on this problem after 90 trials. Consistent with predictions derived from Spiker's theory, it was found that the addition of one nonspatial dimersion resulted in solution, and that the greater the number of nonspatial dimensions present, the better the learning.  相似文献

This study analyzed the strategies that children ages 5 through 8 years used on two modified versions of Inhelder and Piaget's (The early growth of logic in the child. New York: Norton, 1964) class inclusion task. In two experiments, children were tested on Wilkinson's (Cognitive Psychology, 1976, 8, 64–85) “percept” inclusion task in which distinctive features marked both supraordinate and subclasses. It was hypothesized that children who fail standard Piagetian inclusion tasks succeed on the “percept” task by counting and comparing mutually exclusive features rather than using features as markers for classes and subclasses. The hypothesis was supported by children's performances on “percept” tasks in which solutions based on feature counting conflicted with solutions based on consideration of class inclusion relations. In two other experiments, children answered part-whole and part-part comparison questions in which both terms were described as classes and/or subclasses, or in which one of the two terms was described as a collection (e.g., a bunch of grapes). These experiments contrasted Markman and Seibert's (Cognitive Psychology, 1976, 8, 561–577) “organization” hypothesis that the greater psychological integrity of collections facilitates reasoning on part-whole comparison problems with the hypothesis that the faciltative effect results from the “large number” connotation of collective nouns. Results on collection problems in which parts were described as collections supported the “large number” hypothesis. Results were discussed in terms of their implications for Piaget's theory.  相似文献

Mothers' selections of category names in object-naming tasks were examined using the levels of categorization defined by Eleanor Rosch (E. Rosch. In T. Moore (Ed.), Cognitive development and the acquisition of language, New York: Academic Press, 1973. E. Rosch. In E. Rosch & B. Lloyd (Eds.), Cognition and categorization. Hillsdale, N.J.: Erlbaum, 1978. E. Rosch, C. Mervis, W. Gray, D. Johnson, & P. Boyes-Braem. Cognitive Psychology, 1976, 8, 382–439). The effect of three variables—Presentation Context, Taxonomy, and Age (of person for whom mother was naming the items)—on mothers' choice of category names, was also investigated. The stimuli were 36 photographs of common concrete objects representative of four taxonomies. Forty mothers named the stimulus items for their 2-year-olds (N = 20), for their 4-year-olds (N = 20), and for the Experimenter. The category labels that children of both ages used when naming the same items, and mothers' independent predictions of the names their children would use in the naming task, were recorded. Contextual factors were found to have a primary role in determining mothers' selections of category names and the three independent variables had a complex and dynamic effect on mothers' naming practices.  相似文献

A confusion model is defined as a model that decomposes response probabilities in stimulus identification experiments into perceptual parameters and response parameters. Historically, confusion models fall into two groups. Models in Group I, which includes Townsend's (Perception and Psychophysics, 1971, 9, 40–50) overlap model, were developed on the basis of the notion that stimulus identification is mediated by a finite number of internal states. We call the general class of models that have this processing interpretation finite state confusion models. Models in Group II, which includes Luce's (R. O. Luce et al., Eds., Handbook of Mathematical Psychology (Vol. I), New York: Wiley, 1963) biased choice model, were not developed on the basis of an explicit processing interpretation. It is shown here that models in Group II are not finite state confusion models. We prove in addition that except for Falmagne's (Journal of Mathematical Psychology, 1972, 9, 206–224) simply biased model models in Group II belong to a certain class of infinite state confusion models, namely, models asserting that stimulus identification is mediated by a continuous space of vectors representing detector activation levels.  相似文献

The purpose of this paper is to respond to D. Elkind's (1985, Developmental Review, 5, 218–226) reply to D. Lapsley and M. Murphy's (1985, Developmental Review, 5, 201–217) critique of the adolescent egocentrism theory. After a reprise of the issues in contention, we address the problem of theoretical consistency and self-other differentiation in Dr. Elkind's (1967, Child Development, 38, 1025–1034) theory. The role of formal operations in the Lapsley and Murphy (1985) account of the imaginary audience and personal fable is revised, and the empirical support for Elkind's theory is reviewed. We conclude that there are good conceptual and empirical grounds for doubting the major assumptions of the adolescent egocentrism theory, and that the Lapsley and Murphy (1985) framework has promise in suggesting theoretical integration with other approaches to the self.  相似文献

This study compared the predictive accuracy of measured versus expressed interests over a 21-year period using as a criterion occupational membership at age 36. Subjects were 83 males whose measured and expressed interests were elicited at ages 15, 18, and 25. The Strong Vocational Interest Blank was used to determine measured interests while expressed interests were determined through a combination of questionnaires and interviews. C. McArthur's (Journal of Applied Psychology, 1954, 38, 346–353) method was employed to determine the predictive validity of subjects' measured interests. The predictive validity of expressed interests was determined by using A. Roe's (The psychology of occupations. New York: Wiley, 1956; Journal of Counseling Psychology, 1957, 4, 212–217) scheme for occupational classification to code occupational preferences and compare them to age 36 occupations. Results indicated that at each point in the study expressed interests were slightly better predictors of age 36 occupational membership than measured interests. Supplementary analyses revealed no relationship between the extent to which subjects' measured or expressed interests corresponded to age 36 occupations and either overall job or career satisfaction.  相似文献

The constant-ratio rule (CRR) and four interpretations of R. D. Luce's (In R. D. Luce, R. R. Bush, & E. Galanter (Eds.), Handbook of mathematical psychology (Vol. 1). New York: Wiley, 1963) similarity choice model (SCM) were tested using an alphabetic confusion paradigm. Four stimulus conditions were employed that varied in set size (three, four or five stimulus elements) and set constituency (block letters: A, E, X; F, H, X; A, E, F, H; A, E, F, H, X), and were presented to each subject in independent blocks. The four interpretations of the SCM were generated by constraining one, both, or neither of its similarity and bias parameter sets to be invariant in across-stimulus set model predictions. The strictest interpretation of the SCM (both the similarity and bias parameters constrained), shown to be a special case of the CRR, and the CRR produced nearly equivalent across-set predictions that provided a reasonable first approximation to the data. However, they proved inferior to the least strict SCM (neither the similarity nor bias parameters were constrained; the common interpretation of the SCM in visual confusion). Additionally, the least strict SCM was compared to J. T. Townsend's (Perception and Psychophysics, 1971, 9, 40–50, 449–454) overlap model, the all-or-none model (J. T. Townsend, Journal of Mathematical Psychology, 1978, 18, 25–38), and a modified version of L. H. Nakatani's (Journal of Mathematical Psychology, 1972, 9, 104–127) confusion-choice model. Both the least strict SCM and confusion-choice models produced nearly equivalent within stimulus set predictions that were superior to the overlap and all-or-none within-set predictions. Measurement conditions related to model structure and equivalence relations among the models, many of them new, were examined and compared with the statistical fit results of the investigation.  相似文献

First, third, and fifth graders (7.1, 8.8, 11.1 years old) performed semantic, acoustic, and orthographic orienting activities to different words in a list. Without forewarning, their free recall of the words was tested after the orienting activity. The semantic task yielded better recall than the acoustic or orthographic tasks, but the latter two did not differ. Age differences in recall were absent, and the effect of the three orienting tasks did not vary as a function of the child's age. The results support a direct extension of levels of processing theory (Craik, F. I. M., & Lockhart, R. S. Journal of Verbal Learning and Verbal Behavior, 1972, 11, 671–684) to children's memory. An obligatory-optional encoding distinction was suggested as a developmentally relevant addition to the levels of processing framework.  相似文献

Perceived sex appropriateness of the work situation is believed to constrain work opportunities, particularly for women. However, sex appropriateness may be defined either with respect to the entire job or with respect to the tasks which comprise the job. In this study sex appropriateness of job tasks was examined by obtaining subjective estimates of the masculinity-femininity of the job requirement dimensions defined by the Dictionary of Occupational Titles (DOT). Results indicate that interacting with things is perceived as masculine, interacting with people is perceived as feminine, and interacting with data is perceived as falling between the other two. There is less agreement on the masculinity-femininity of specific types of interactions with data, people, and things. Sex appropriateness of specific requirements was found to be only moderately associated with the DOT's assessment of the complexity of those requirements. Further, sex appropriateness of job requirements was not highly related to the job sextypes established by Shinar (Shinar, E. H. Journal of Vocational Behavior, 1975, 7, 99–110) and Krefting et al. (Krefting, L. A., Berger, P. K., and Wallace, M. J. Jr. Journal of Vocational Behavior, 1978, 13, 181–191). This suggests that sex appropriateness of a job and sex appropriateness of the tasks which comprise the job are distinct, separate concepts.  相似文献

In two experiments, first- and fourth-grade subjects (age 6 and 9 years) performed a speeded card-sorting task with either integral or nonintegral dimensions. The dimensions were so arranged that subjects sorted on three types of task: (1) single dimension, (2) correlated dimensions, and (3) orthogonal dimensions. Results of the first experiment indicate that both first- and fourth-grade subjects sorted integral dimensions in a manner not qualitatively different from that of the adult (Garner & Felfoldy, Cognitive Psychology, 1970, 1, 225–241). In comparison with single-dimension tasks, performance was facilitated on the correlated-dimensions tasks and interference was observed on the orthogonal-dimensions tasks. Performances with nonintegral dimensions revealed an age-related processing difference. Fourth graders sorted nonintegral dimensions like the adult; no differences in performance were observed between the tasks. In contrast, first-graders sorted nonintegral dimensions as if they were integral. Interference was consistently observed on orthogonal-dimensions tasks. On correlated-dimensions tasks, interference was observed on easy tasks and redundancy facilitated difficult tasks. In the second experiment, first graders showed consistent facilitation on the correlated-dimensions task; all other results were indentical to those of Experiment I. The results were interpreted as consistent with perceptual learning theory (Gibson, Principles of perceptual learning and development. New York: Appleton-Century-Crofts, 1969).  相似文献

Internal and external subjects, who previously filled out Rotter's (1966) I-E scale, were asked to score the I-E scale of “another student”. Subjects were exposed to “an other's” score of either 0, 5, 10, 16, or 23, and were asked to rate themselves and the “other” on an evaluative questionnaire. It was predicted that ratings of the “other” would increase in positivity to the extent the “other” scored as an internal. A reverse direction was predicted for an index of negative evaluations. The predictions were confirmed. The results suggest that internal locus of control is a societal value. The findings did not support either Hannah's (1973) hypothesis that internals are more responsive to a need for social approval, or Byrne's (1969) similarity hypothesis.  相似文献

The potential causes of decrements in children's understanding of big and tall (Maratsos, 1973, Maratsos, 1974, 10, 367–375) are reconsidered. On the basis of data from English-speaking children, two of these hypotheses, the Strong Cognitive Hypothesis and the Strong Semantic Hypothesis, offer equally plausible explanations for those decrements. However, data from Arabic-speaking children between 2;9 and 6;3, who do not show a similar decrement in their understanding of kabiir, support the Strong Semantic Hypothesis that decrements in English-speaking children's understanding of big and tall are due to their positing semantic features such as [+ Vertical] for one word and overgeneralizing them to related words. This, in turn, supports Carey's (M. Halle, J. Bresnan, & G. Miller (Eds.), Linguistic theory and psychological reality. Cambridge, Mass.: MIT Press, 1978. Pp. 264–293) theory that features are abstracted out for words after children are able to use those words correctly on the basis of stored haphazard examples. Further, the results support the view that children at least sometimes posit features for a word on the basis of its individual privileges of occurrence, rather than on the basis of what that word contrasts with.  相似文献

The psychological meaning and predictive value of a person's vocational aspirations were examined by applying Holland's typology to the vocational aspirations of high school juniors (N = 1005), college juniors (N = 692), employed adults (N = 140), and a second sample of college students studied over a one-year interval (N = 624). The aspirational data were obtained from the Daydreams section of the Self-Directed Search (Holland, 1972). Categorical and correlational analyses show that a person's retrospective vocational aspirations have coherence and yield efficient predictions of subsequently expressed choice. In addition, the degree of coherence or similarity among a person's vocational aspirations provides a potentially useful index of a person's decision-making ability.  相似文献

L. S. Gottfredson's preceding comment (Journal of Vocational Behavior 1983, 23, 203–212)is characterized by undocumented and arbitrary assertions. Moreover, we still maintain and cite further evidence that the features of the stages she describes represent an implausible account of development. We conclude that there is nothing in either L. S. Gottfredson's original (Journal of Counseling Psychology 1981, 28, 545–579) article or her preceding paper that leads us to alter our belief that the views we present in our own article (Journal of Vocational Behavior 1983, 23, 179–212) will be useful for the future development of vocational theory and intervention.  相似文献

Task differences were assessed with 120 first graders in a 2 × 3 × 3 factorial design combining Socioeconomic level (middle vs lower), Concepts (conservation of length, transitivity of length, and conservation of continuous quantity), and Tasks (three tasks for each concept selected on the basis of frequency of usage). As predicted, task by concept interactions were found on all four task response measures. This finding is consistent with Piaget's concept of horizontal decalage and with Flavell and Wohlwill's competence-performance model, which proposes that intermediate phases of stage transition are characterized by considerable intertask differences and initial and final phases by intertask consistency in performance. The importance of investigating the effects of task variables on multiple dependent measures at various age levels and points in time was emphasized. Concept, task, and socioeconomic class differences were also found on some of the measures.  相似文献

Based on a review of reaction time studies, a model of mental arithmetic performance which emphasizes the process of fact retrieval from organized memory representations was proposed (M. H. Ashcraft, Developmental Review, 1982, 2, 213–236). In contrast to this view A. J. Baroody (Developmental Review, 1983, 3, 225–230) proposes that most mental arithmetic performance depends on procedural knowledge such as rules, heuristics, and principles. While Baroody's idea is both intriguing and potentially important, its exposition is quite vague and speculative. Without concrete suggestions as to the nature of the proposed rules and heuristics, especially for routine problems like 4 + 3 and 8 × 5, Baroody's proposal appears to be pertinent only to special cases like N + 0 and N + 1. Lacking this sort of elaboration, the alternative does not provide a useful or compelling explanation of the existing Chronometric results, and seems, at best, to be premature.  相似文献

A framework for behavioral observation is described in which the processing of a stream of behavior is influenced by an individual's prior knowledge about behavior, organized into cognitive “schemas.” It is proposed that observational goals determine the selection of goal-relevant schemas which, in turn, influence the observer's processing of an actor's behavior. Subjects watched a series of videotaped sequences featuring a female actor with instructions either to form an impression of her or to remember the details of the tasks she engaged in. They were then asked to answer questions that were either consistent or inconsistent with these instructions. Subjects were also instructed to unitize the actions or events that occurred in the sequence (D. A. Newtson, Journal of Personality and Social Psychology, 1973, 28 28–38). According to the unitizing measure, subjects observing with different goals attended to different behavioral features. Further, impression-forming subjects were apparently more influenced by their implicit theories of personality than were task-learning subjects when asked to give ratings of the actor's personality, and task-learning subjects were relatively more accurate in recalling task-related details. Implications of this framework and these results for research in behavioral unitization and implicit personality theory are discussed.  相似文献

Preschool children's understanding of temporal relationships was examined in terms of their comprehension of sentences containing clauses linked by before and after. The relative importance of order of mention and main-subordinate relations strategies in children's interpretation of temporal order information was also evaluated.Divergent error patterns emerged on the tasks; omissions prevailed on the two tasks involving response to commands, reversals prevailed on the other. Further examination revealed that omissions reflected ambiguity in the linguistic structure of commands. Thus the effect of main-subordinate relations was confounded with directness of command. On all comprehension tasks, however, performance was superior on sentence forms in which order of mention and order of occurrence correspond.  相似文献

The Ramak and Courses interest inventories (Meir, 1974; Meir, Sohlberg, & Barak, 1973) based on Roe's 1956 occupational classification, were modified for use with subjects who answer negatively to most items in the traditional forms. One hundred thirty-six males, aged 19–21, responded to the Ramak and Courses inventories with the R ? A (Refuse, Undecided, Agree) scale. The split half reliability of the modified inventories is 0.75, and their occupational structure has the same shape and arrangement as the inventories with the Y ? N scale. Negative respondents give more positive responses (p < .05) on the modified forms than on the traditional ones.  相似文献
