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

This research had two aims. The first was to test three explanations of performance on N-term series tasks by young children: the labeling model of B.DeBoysson-Bardies and K. O'Regan (1973), Nature (London), 246, 531–534, the sequential-contiguity model of L. Breslow (1981, Psychological Bulletin, 89, 325–351), and the ordered array or image model of C. A. Riley and T. Trabasso (1974, Journal of Experimental Child Psychology, 17, 187–202). In the first experiment, 5-year-old children were taught additional premises which would interfere with labeling and sequential-contiguity processes, but not with forming an ordered array. Reasoning performance was essentially comparable to previous results with the paradigm, thus supporting the ordered array model. The second aim was to reexamine children's ability to learn sets of premises which can be assembled into an ordered array, since there was reason to believe that previous studies had created false positives. In the second experiment, 3- to 7-year-old children were taught either overlapping (a > b, b > c, …) or nonoverlapping (a > b, c > d, …) premises. Overlapping premises can be integrated into an ordered array (a, b, c, d, e), but nonoverlapping premises cannot. However, the overlapping condition proved more difficult, and the success rate for preschoolers (312- to 412-year-olds) was of zero order. This raises doubts about their ability to learn a set of premises of the kind required for transitive inference. These doubts were strengthened by the third experiment which showed that when premises were not presented in serial order, preschool (312- to 412-year-old) children could not learn the premises of an N-term series task.  相似文献

The present study reassesses trends in motivation to manage among college business students (N = 216). Motivation to manage scores are compared with J. B. Miner's (Personnel Psychology, 1974, 27, 605–613) results for three periods since the early 1960s, across two types of universities—public and private, and between males and females. Results indicate that the downward trend in motivation to manage scores appears to be reversing; business students at the private university scored higher on motivation to manage than those at the public university, and males scored higher than females. Implications for vocational research are discussed.  相似文献

A time-sharing paradigm was used to assess language lateralization in language-disordered and normal children aged 4–7 years. Several expressive language tasks as well as a vocal, but nonlinguistic, task were administered concurrently with unimanual finger tapping. Dependent variables were percent disruption scores and number of syllables produced per concurrent trial. All language concurrent tasks produced tapping reductions for both hands for both groups. This result contrasts to similar time-sharing studies claiming asymmetrical interference and hence language lateralization in children (N. White & M. Kinsbourne, 1980, Brain and Language, 10, 215–223; J. Obrzut, G. Hynd, A. Obrzut, & J. Leitgeb, 1980, Brain and Language, 11, 181–194). A multiple regression analysis revealed a significant interaction effect differentiating language-disordered from normal children. Normals exhibited a parallel response pattern for speech and tapping (both increased or decreased in rate) under all lateralization conditions. Language-disordered children exhibited an inverse response pattern (e.g., if speech output increased, tapping rate decreased) only under left-hemisphere time-sharing.  相似文献

Research by Markman (1979) suggests that children up to 12 years of age do not spontaneously detect logical inconsistencies. The present study was directed to factors which may limit children's ability to recognize their failures to understand. A task was devised which involved materials that were clearly based on children's experiences, and which involved premises and conclusions which were presented contiguously, rather than being interspersed among other sentences. Ninety-six 5-, 6-, and 7-year-old children were asked to judge the acceptability of eight three-sentence “stories” told by a puppet, and were asked to justify their responses. The stories differed in whether they were consistent or inconsistent, and in whether the principle upon which a story's consistency depended was implicitly or explicitly stated. The results showed developmental differences. By Age 7 years, most children were quite capable of evaluating sentences for their logical consistency. Five-year-olds, however, did not perform as well on the task, especially when the information upon which the logical cohesiveness of the stories rested was implicitly, rather than explicitly, stated. An examination of the justifications provided by these children revealed that they tended to question the empirical validity of individual sentences, rather than integrate the story as a whole and examine its overall logical structure.  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

On mediation     
The mediation-nonmediation dichotomy proposed by the Kendlers (Psychological Review, 1962, 69, 1–16) and subscribed to by Cole and Medin (Journal of Experimental Child Psychology, 1973, 15, 352–355) is reviewed and critiqued. It is proposed that the appropriate question for research is how children mediate, not when they mediate.  相似文献

Data relating novelty preference to age for normal children are inconsistent, although a current theory predicts a developmental shift from novelty to familiarity preference in selective learning (D. Zeaman, 1976, in T. J. Tighe & R. N. Leaton (Eds.), Habituation: Perspectives from child development, animal behavior, and neurophysiology (pp. 297–320), Hillsdale, NJ: Erlbaum). Support for this theory, however, has been derived primarily from studies of retardate learning. Normal children's novelty preference was examined within a modified Moss-Harlow (E. Moss & H. F. Harlow, 1947, Journal of Comparative and Physiological Psychology, 40, 333–342) design to compare Zeaman's model with that of S. L. Witryol and W. Wanich (1983, The Journal of Genetic Psychology, 143, 3–8). Each of 16 problems, consisting of three single-stimulus demonstration trials and one two-choice test, was administered to 180 children (mean CA 4, 5.5, and 7 years) in three reward conditions. Novelty was manipulated by varying stimulus familiarization in the demonstration trials. Experiment 1 showed strong preferences for novel over familiar (demonstrated) stimuli at each age. Experiment 2 revealed novelty preference across age levels, two levels of reward contrast, and two levels of task difficulty. It was reasoned that Moss-Harlow tasks designed for normal children typically present a much higher level of difficulty than that intended by researchers. Furthermore, developmental decreases in novelty preference by retardates may derive from (a) transfer of training from prior experiments and (b) specific, repetitive instructions which may have directed attention away from stimulus novelty.  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

Further to the debate between Kearins (1978) and Drinkwater (1978), visual memory skills of Aboriginal and white Australian children were examined using Drinkwater's version of Kim's game with desert Aboriginal and rural white children. Older children remembered more than younger ones, and Aboriginal children recalled more natural objects than white children. There was no difference between the groups in recall of manufactured objects, nor between recall of manufactured and natural objects within each group. Aboriginal children remembered significantly more objects overall than white children when the task was first administered. On a second occasion, after a procedure designed to orient children towards the use of predominantly visual rather than verbal memorising strategies, there was no significant difference between the groups.  相似文献

This study compared leisure activities with occupational membership as criteria for determining the concurrent validity of the Holland and Basic Interest scales of the Strong Vocational Interest Blank (Form T399). Subjects were 89 thirty-six-year-old males representing a variety of occupations. R. H. Dolliver's (Journal of Counseling Psychology, 1975, 22, 199–203) two methods for assessing validity were used: highest single scores on relevant scales and scores above established cutoff points on relevant scales. Results indicated greater congruence between interest scales and occupations than interest scales and leisure activities, except when Basic Interest scale cutoff scores were used. After chance factors were taken into account, Holland scales were found to be more accurate than Basic Interest scales in identifying occupations and in identifying leisure activities when highest scale scores were used. Using cutoff scores, Basic Interest scales were more accurate than Holland scales in identifying leisure activities. Supplementary analyses indicated that the validity of the Holland and Basic Interest scales increases when they are presumed to reflect either current occupation or preferred leisure activity. Results of this study were compared with Dolliver's (1975) findings.  相似文献

The development of analogical reasoning processes.   总被引:2,自引:0,他引:2  
Two experiments were conducted to test the generalizability to children of a theory of analogical reasoning processes originally proposed for adults (R. J. Sternberg, Psychological Review, 1977a, 84, 353–378; R. J. Sternberg, Intelligence, information processing, and analogical reasoning: The componential analysis of human abilities, Hillsdale, N.J.: Lawrence Erlbaum Associates, 1977b) and to examine the development of analogical reasoning processes in terms of five proposed sources of cognitive development: (a) availability of component operations; (b) strategy for combining multiple component operation; (c) strategy for combining multiple executions of the same component operation; (d) consistency in use of strategy; (e) component-operation latency and difficulty. Between 15 and 21 subjects in each of grades 2, 4, 6, and adulthood (ages 8, 10, 12, and 19 years, respectively) were tested in their ability to solve analogies of systematically varied difficulty. Performance was measured in terms of latencies for items solved correctly, latencies for all items solved, and error rates. A slightly modified version of the Stenberg, 1977(a), Stenberg, 1977(b) theory was found to be applicable to the data for each of the age levels tested. In analogies with perceptually separable attributes, change over age was found in sources (d) and (e) noted above. In analogies with perceptually integral attributes, change over age was found in sources (a), (c), (d), and (e). Developmental trends were discussed in terms of past theory and findings, and possible reasons for differences in developmental patterns between the two kinds of analogies were suggested.  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

Three experiments are reported in which kindergarten and first-grade children were given one-trial multidimensional reasoning tasks that were modifications of those used by T. C. Toppino (1980, Journal of Experimental Child Psychology, 30, 496–512). In the first two experiments, the nature of the stimulus compounds (partitioned or unitary) was varied in a series of tasks of increasing complexity. First-grade children (Experiment 1) and kindergarten children (Experiment 2) performed extremely well on all of the tasks presented. Experiment 3 was designed to identify factors that contribute to these high levels of performance, relative to those obtained under the conditions used by Toppino (1980). The results indicated that a combination of feedback information and preliminary experience with simple forms of the tasks are sufficient to produce the high performance levels, and that the verbal labeling of stimulus components is not an essential constituent of the training.  相似文献

A terminology for general choice models based on the choice axiom is given. It applies to all kinds of choice experiments, such as confusion choice experiments, paired comparisons, triadic comparisons, directional rankings, scores on binary test items, and others. Maximum likelihood estimation for such general choice models is considered. Conditions for the uniqueness of maximum likelihood estimates are given, and it is shown that the estimates can be derived by iterative proportional fitting. This offers the opportunity of a general test of the choice axiom for all kinds of choice experiments using the likelihood ratio. The estimation and testing procedure is applied to data from a form recognition experiment, reported by W. A. Wagenaar (Nederlands Tijdschrift voor de Psychologie, 1968, 23, 96–108).  相似文献

In a recent article, H. D. Day, D. Marshall, B. Hamilton, and J. Christy (1983, Journal of Research in Personality, 17, 97–109) have reported on a series of simulation studies designed to investigate properties of various coefficients of behavior stability as applied to cross-situational data. The results of their research have prompted them to suggest precautions regarding the measurement of behavioral regularity with conventional indices of response consistency. A critical review of their paper reveals aspects of the data, procedures, and interpretations of Day et al. (1983) which undermine many of their conclusions. Notable problems include (a) inappropriate comparisons of internal consistency reliability coefficients based on nonparallel analyses, (b) anomalous data which may be due to errors of rounding or recording, and (c) the failure to recognize certain assumptions underlying reliability estimation. More importantly, it is shown that the investigation of Day et al. (1983) represents primarily an empirical verification of several measurement principles for which algebraic proofs are amply documented.  相似文献

The use of a transparent model in a drawing task allows all the features of the model to remain visible whatever its orientation. N. H. Freeman (1980, Strategies of Representation in Young Children, New York/London, Academic Press) found that when drawing a transparent glass with its handle turned away, children made more canonical errors (drawing the handle at the side) than when drawing a similarly orientated opaque cup. According to Freeman being able to see the handle in a noncanonical orientation “triggers” a canonical representation of the object (N. H. Freeman 1980, p. 252). Two experiments are reported which investigated children's drawings of transparent objects. The drawings obtained from children between 4 and 7 years old produced two major findings. First, the tendency toward canonicality when drawing a glass with its handle turned away was significantly reduced when two glasses in differeing orientations were presented side by side. Second, the number of canonical errors was lower when the glass was filled with milk (thus hiding the handle). This latter finding confirms that of N. H. Freeman (1980). However, the first suggests that children use situationally appropriate information when drawing transparent objects in a way similar to that noted by A. M. Davis (1983, Contextual Sensitivity in Young Children's Drawings, Journal of Experimental Child Psychology, 35, 478–486) using opaque objects.  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
