This report presents findings for a set of dizygotic twins at age 4 years 9 months. The male was diagnosed as specifically language impaired. For both children, the left-right perisylvian configuration was atypical. Only the male's configuration was symmetrical, a finding in line with autopsy data reported for subjects with "developmental dyslexia" who also may have had a form of language impairment. In addition, the male had an atypical (L greater than R) configuration of the cerebral hemispheres, a finding not seen in his twin, or in a series of volunteers without a history of developmental language impairment. The in utero effects of gonadal hormones that may account for these findings are discussed. 相似文献

Summary It is suggested that visual-imaginal encoding of actions, i.e., imagining seeing somebody else performing a described action, should be distinguished from motor-imaginal encoding, i.e., imagining how one performs the action oneself. While both kinds of encoding should provide good item-specific information, only visual-imaginal encoding should also lead to good relational encoding of word pairs. In three experiments in which subjects had to learn verb pairs, we obtained supporting data for this assumption. Although CR performance was equal to FR performance under visual-imaginal encoding, under motorimaginal encoding CR performance was worse than FR performance. In principle, this finding parallels results obtained with imagined noun pairs and with performed verb pairs.The research reported here was supported by a grant from the Deutsche Forschungsgemeinschaft to J. Engelkamp and Hubert D. Zimmer. The paper was prepared during a stay of these authors at the Centre d'Études de Psychologie Cognitive, enabled by a grant of PROCOPE 311 pro 相似文献

The present study aims to identify factors that may influence the dissociability of number magnitude processing and arithmetic fact retrieval at the behavioural level. To that end, we assessed both subtraction and multiplication performance in a within-subject approach and evaluated the interdependence of unit-decade integration measures on the one hand as well as sex differences in the interdependence of performance measures on the other hand. We found that subtraction items requiring borrowing (e.g. 53–29 = 24, 3 < 9) are more error prone than subtraction items not requiring borrowing (e.g. 59–23 = 34, 9 > 3), thereby demonstrating a borrowing effect, which has been suggested as a measure of unit-decade integration in subtraction. Furthermore, we observed that multiplication items with decade-consistent distractors (e.g. 6 × 4 = 28 instead of 24) are more error prone that multiplication items with decade-inconsistent distractors (e.g. 6 × 4 = 30 instead of 24), thereby demonstrating a decade-consistency effect, which has been suggested as a measure of unit-decade integration in simple multiplication. However, the borrowing effect in subtraction was not correlated with the effect of decade consistency in simple multiplication in either men or women. This indicates that unit-decade integration arises from different systems in subtraction and multiplication. Nevertheless, men outperformed women not only in subtraction, but also in multiplication. Furthermore, subtraction and multiplication performance on correct solution probes were correlated in women, but unrelated in men. Thus, the view of differential systems for number magnitude processing and arithmetic fact retrieval may not be universal across sexes. 相似文献

The present study replicated and extended research concerning a recently suggested conceptual model of the underlying factors of dimension ratings in assessment centers (ACs) proposed by Hoffman, Melchers, Blair, Kleinmann, and Ladd that includes broad dimension factors, exercise factors, and a general performance factor. We evaluated the criterion-related validity of these different components and expanded their nomological network. Results showed that all components (i.e., broad dimensions, exercises, general performance) were significant predictors of training performance. Furthermore, broad dimensions showed incremental validity beyond exercises and general performance. Finally, relationships between the AC factors and individual difference constructs (e.g., Big Five, core self-evaluations, positive and negative affectivity) supported the construct-related validity of broad dimensions and provided further insights in the nature of the different AC components. 相似文献

The impact of the activation of positive and negative components of an ethnic stereotype on judgments of responsibility for both positive and negative stereotypic behaviors was considered. Overall, stereotype activation biased judgments in a stereotype-consistent manner, across both positive and negative scenarios. Generalization of these judgments to more global trait perceptions of the target was limited to the negative scenario. Results are discussed in terms of both the use of stereotypes as inferential shortcuts and in-group favoritism mechanisms. 相似文献

Kant's response to Cartesian scepticism is often characterized in the following way. Whereas Descartes drives a wedge between subjective experience and objective reality, Kant argues that there could be no such thing as experience at all if reality were not itself structured in just the way our thought about it is structured. This picture of Kant's response to Descartes portrays him as succeeding, where Descartes fails, in arguing directly from the nature of experience to the nature of reality; as subscribing, therefore, to Descartes' view that one is immediately aware only of one's own mental states, but as seeing a way out of the subjective predicament. I maintain that this picture is deeply flawed. Kant's transcendental argument is in fact a thoroughgoing critique of Descartes' subjectivism, and destroys the Cartesian barrier to recognizing that our awareness of reality is unmediated and direct. 相似文献

Nous rapportons dans cet article des données nouvelles sur les comportements d'escalade et de descente d'un escalier hélicoïdal par 12 enfants, dans un local spécialement aménagé. Âgés entre 17 et 21 mois au début de la recherche, ils ont été répartis en deux groupes: pour l'un, la première marche était triangulaire; pour l'autre, quadrangulaire. Les měmes enfants ont été étudiés entre 23 et 27 mois dans les měmes conditions et selon le měme protocole, mais avec une inversion de la configuration de la première marche. On observe que: (1) dès la classe d'âges de 17 à 21 mois, les enfants des deux groupes privilégient le pied droit pour attaquer la première marche, avec le plus souvent alternance des deux pieds sans diminution du pas et sans arrět; (2) la configuration de la première marche joue un rôle significatif dans la fréquence de choix du pied d'attaque en début d'escalade et en fin de descente; (3) les comportements en fin d'escalade et en début de descente apparaissent influencés par la configuration du sommet de l'escalier et par la configuration de la première marche d'escalade; (4) entre 23 et 27 mois, l'influence des facteurs de développement est particulièrement nette en début d'escalade et en fin de descente; (5) les comportements en fin d'escalade et en début de descente apparaissent influencés par une combinaison de facteurs de développement, de la configuration du sommet de l'escalier, des expériences individuelles au début de l'escalade et des expériences individuelles au cours de la première partie de l'étude. 相似文献

Summary In three experiments the influence of the given-new structure of cleft sentences on picture viewing was examined. Subjects heard cleft sentences and subsequently inspected pictures depicting the agent and the patient of the action mentioned in the sentence. Each sentence-picture pair was preceded by an adequate context sentence and a context picture. It was demonstrated that the delineation of the agent or of the patient in the sentence was looked at longer when it was marked as new information in the sentence that described the picture than when it was marked as old information. We interpret these findings to mean that the new information of a cleft sentence sets up a focus of attention in the cognitive structure and that this prolongs the time spent in the inspection of a delineation of the focal concept. 相似文献

Child health-care appointments that are not kept are an important pediatric problem. Previous research has shown that reducing effort (with a parking pass) and reminding patients (with mailed and telephone reminders) significantly improved appointment keeping for first-time and patient-scheduled appointments. This study, using a posttest-only group design, evaluated the effects of various combinations of that intervention applied to clinic-scheduled follow-up appointments. All combinations of the intervention significantly increased cancellations, but none increased appointments kept or decreased appointments not kept significantly. Log linear analyses showed that the lag time between scheduling and the appointment significantly influenced appointment keeping. The results suggest that if clinics want to increase cancellations, a mailed reminder and effort reduction are sufficient. To increase appointment keeping, other interventions, such as reduced lag time, may be necessary. 相似文献
