A good deal of activity in contemporary aphasia research goes under the label "neurolinguistics." What characterizes this enterprise is, among other things, its goal of identifying neurally realized computational subsystems that support language processing. In this essay the thesis is put forward that this goal will not be served by the continued exploitation of the classical (Wernicke-Lichtheim) taxonomic categories. These categories, it is argued, cannot by virtue of their "polytypic" structure support the relevant neurolinguistic generalizations. 相似文献

To study spatial representation, Kosslyn, Pick, and Fariello (Child Development, 1974, 45, 707–716) asked preschoolers and adults to learn toy locations in a room divided into quadrants. When asked to rank order the closeness of toys, preschoolers exaggerated distances between objects separated by opaque or transparent barriers; adults distorted across opaque barriers only. The findings were interpreted as showing that children's spatial representations may rely more than adults' on functional distance and/or that children may have more difficulty than adults keeping many objects in mind simultaneously (integrative processing capacity). The Kosslyn et al. procedure was repeated here with first graders and adults, using either rank ordering techniques or direct distance estimations. Interactions of age and barrier appeared for the rank ordering measure only. Children showed a greater tendency than adults to group their rankings by quadrant. With the distance estimation measure, adults were quantitatively more accurate than children, at least among males; barrier effects interacted with sex and distance, but not age. These findings suggest the importance of integrative processing capacity, and that different dependent measures may tap different processes. 相似文献

Assume an X-linked gene in two alleles mediates performance on field dependent-independent tests such as the rod-and-frame test. Only the recessive gene with relative frequency q facilitates field independence. Other genotypes lead to field dependence. Under a simple genetic model, field dependence-independence may be viewed as outcomes of a discrete random variable B with field independent and dependent probabilities πiq and 1 ? πiq for men, and πiq2 and 1 ? πiq2 for women, respectively. The parameter πi is a maturational ageindexed parameter, 0 < πi ≤ 1, monotonically increasing with development until maturity when πk = 1. Observations of performance are made on a random variable W of the form W = B + N, where N is normal in distribution independent of B; N represents a composite of influences including error. The model implies testable age-related between- and within-sex predictions regarding E(W) and Var(W), predictions which appear to coincide with major empirical findings; it also generates novel predictions. For instance, W is a mixture of normals distribution. The model is briefly evaluates in two data sets. 相似文献

This study was a test of the feasibility of a method for quantifying the physical features of a high quality preschool setting. Play resources were selected and arranged for: (a) visibility and access, (b) variations in complexity level, and (c) availability of alternate selections for play choices. Independent analyses from two urban day care settings (N=60) provided concurrent replication of the test of the hypotheses. As predicted, significant increases in participation were recorded from baseline to experimental treatment, and concomitant decreases from treatment to post-treatment. Conflicts rarely occurred during baseline or treatment. However, the increase in conflicts during post-treatment was viewed as a significant effect of the cessation of treatment. Treatment condition did not affect the statistical prevalence of waiting and watching behaviors, but did appear to influence the functions served by these noninteractions. Implications of these results for application by early childhood personnel are offered. 相似文献

Children and adolescents as producers of their own development 总被引:1,自引:0,他引:1

Interest in the historically changing contexts of human life has been associated with the elaboration of a life-span view of human development. This view holds that all levels of the context, including the biological, psychological, and sociocultural, change in reciprocal relation to one another. As a consequence of being embedded in a context which they both influence and are influenced by, children and adolescents may promote their own development. One way this occurs is that as a consequence of their characteristics of physical and behavioral individuality people promote differential reactions in their socializing others (e.g., parents, teachers, or peers); these reactions feed back affecting further development. My colleagues and I have conducted research that describes such child and adolescent contributions to development. We have focused on characteristics of physical individuality, such as body type and physical attractiveness, and on characteristics of behavioral individuality, such as behavioral style or temperament. Findings from these studies are conceptualized in terms of a person-context “goodness-of-fit” model. Adaptive development is associated with congruence, or fit, between a person's attributes of individuality and the demands of his or her setting. Implications of this research for illustrating the use of the life-span perspective, and for theory in and practice of intervention, are discussed. 相似文献

Preschoolers' counting: principles before skill 总被引:6,自引:0,他引:6
Three- to 5-year-old children participated in one of 4 counting experiments. On the assumption that performance demands can mask the young child's implicit knowledge of the counting principles, 3 separate experiments assessed a child's ability to detect errors in a puppet's application of the one-one, stable-order and cardinal count principles. In a fourth experiment children counted in different conditions designed to vary performance demands. Since children in the errror-detection experiments did not have to do the counting, we predicted excellent performance even on set sizes beyond the range a young child counts accurately. That they did well on these experiments supports the view that errors in counting—at least for set sizes up to 20—reflect performance demands and not the absence of implicit knowledge of the counting principles. In the final experiment, where children did the counting themselves, set size did affect their success. So did some variations in conditions, the most difficult of which was the one where children had to count 3-dimensional objects which were under a plexiglass cover. We expected that this condition would interfere with the child's tendency to point and touch objects in order to keep separate items which have been counted from those which have not been counted. 相似文献

This study of 597 entering college women investigated the characteristics of people they named as the primary influencers for their initial choices of major. College major was considered analogous to vocational field since the sample of students overwhelmingly gave career goals as reasons for choosing a particular major. Characteristics of these primary influencers were compared with those of a sample of individuals influencing male choices. In addition, characteristics of influencers were compared between those influencing females choosing traditional and nontraditional majors. The results indicate that most students, regardless of gender, were influenced by males, particularly fathers. However, a notable percentage of female students, especially those in traditional fields, were influenced by females. Students whose primary influencers were in fields closely related to their own vocational choices reported being more certain of their choices than students citing influencers in unrelated fields. These findings have implications for model-observer similarity, and may necessitate distinguishing between influential people who provide reinforcement for a choice of major and those who provide specific vocational modeling as well as reinforcement for that choice. 相似文献

The modifiability of older adults' performance on Induction tasks was examined through cognitive training. The posttraining performance of 52 older adults () was assessed with regard to a transfer-of-training paradigm and maintenance of training effects at three posttests (one week, one month, six months). A pattern of differential training transfer across the posttest battery of fluid and crystallized intelligence measures was predicted, with the largest training effects expected for near transfer (Induction) measures. The predicted pattern of training transfer was obtained at one-week and one-month posttests, with significant training effects to the nearest Induction measure. Large retest (practice) effects across posttests also occurred for training and control groups. This research contributes to the position that modifiability of intellectual performance through cognitive intervention extends across the adult life span. 相似文献

Neither M. G. McGee (Developmental Review, 1981, 1, 289–295) nor M. J. Allen, M. A. Wittig, and K. Butler (Developmental Review, 1981, 1, 284–288) suggest any alternative explanation for our finding that water-level performance appears to have an X-linked genetic basis. The power calculations of Allen et al. are found to be faulty, and McGee confuses the hypothesis we tested with a weaker hypothesis. Although the X-linked genetic model is not an adequate model of water-level performance the water-level data fit the X-linked model far better than color blindness and HCN data McGee presents as exemplars of X-linked characteristics. 相似文献
