Although recent studies suggest a strong association between short-term memory (STM) for serial order and lexical development, the precise mechanisms linking the two domains remain to be determined. This study explored the nature of these mechanisms via a microanalysis of performance on serial order STM and novel word learning tasks. In the experiment, 6- and 7-year-old children were administered tasks maximizing STM for either item or serial order information as well as paired-associate learning tasks involving the learning of novel words, visual symbols, or familiar word pair associations. Learning abilities for novel words were specifically predicted by serial order STM abilities. A measure estimating the precision of serial order coding predicted the rate of correct repetitions and the rate of phoneme migration errors during the novel word learning process. In line with recent theoretical accounts, these results suggest that serial order STM supports vocabulary development via ordered and detailed reactivation of the novel phonological sequences that characterize new words. 相似文献

A recent report by the National Research Council (Huey & Wickens, 1993) has identified transitions in task demand as an important dimension for study in vigilance research. This experiment tested the possibility that the effects of such transitions follow a relatively simple psychophysical rule—they are characterized by contrast effects. Transitions in task demand were achieved by shifting subjects from single-task to dual-task monitoring and vice versa. These transitions produced changes in subjects' sensing and decision-making functions that were far more intricate than simple contrast effects. The demand transition issue offers a complex research challenge on both basic and applied levels and warrants further investigation. 相似文献

Reaching toward an object usually consists of a sequence of elemental actions. Using a reaching task sequence, the authors investigated how task elements of that sequence affected feedforward and feedback components of the reaching phase of the movement. Nine right-handed adults performed, with their dominant and nondominant hands, 4 tasks of different complexities: a simple reaching task; a reach-to-grasp task; a reach-to-grasp and lift object task; and a reach-to-grasp, lift, and place object task. Results showed that in the reach-to-grasp and lift object task more time was allocated to the feedforward component of the reach phase, while latency between the task elements decreased. We also found between-hand differences, supporting previous findings of increased efficiency of processing planning-related information in the preferred hand. The presence of task-related modifications supports the concept of contextual effects when planning a movement. 相似文献

Interpersonal dependency and locus of control orientation were studied in obese and nonobese samples. The Interpersonal Dependency Inventory (Hirschfeld, Klerman, Gough, Barrett, & Korchin, 1977) and the I-E Scale (Rotter, 1966) were administered to 106 obese adults in outpatient treatment for obesity. The I-E Scale was also administered to 97 nonobese control subjects. As predicted, the obese subjects were significantly more internally oriented than has been previously identified in obese populations. These findings challenge currently held assumptions about locus of control in obese groups. Although the obese and nonobese subjects maintained similar overall dependency scores, the obese subjects were more likely to show low levels of autonomy in comparison with the nonobese subjects. Interpersonal dependency and locus of control dimensions associated with obese conditions may serve as useful predictor variables influencing obesity treatment approaches and outcome. 相似文献

Experimental philosophy is often presented as a new movement that avoids many of the difficulties that face traditional philosophy. This article distinguishes two views of experimental philosophy: a narrow view in which philosophers conduct empirical investigations of intuitions, and a broad view which says that experimental philosophy is just the colocation in the same body of (i) philosophical naturalism and (ii) the actual practice of cognitive science. These two positions are rarely clearly distinguished in the literature about experimental philosophy, both pro and con. The article argues, first, that the broader view is the only plausible one; discussions of experimental philosophy should recognize that the narrow view is a caricature of experimental philosophy as it is currently done. It then shows both how objections to experimental philosophy are transformed and how positive recommendations can be provided by adopting a broad conception of experimental philosophy. 相似文献

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects. 相似文献

Some theorists suggest that worry is elevated by positive beliefs when stressful events occur. Although several cross-sectional studies have revealed an association between positive beliefs and worry, few longitudinal studies have been conducted on this topic. Moreover, the effect of positive beliefs as a moderator on worry when stressful events occur has not been investigated. Against this background, the present study conducted a two-wave longitudinal survey to examine the moderating role of positive beliefs. One hundred and ninety-four college students voluntarily completed questionnaires. Hierarchical regression analysis showed a prospective relationship between the experience of stressful events and the subjective report of worry. Moreover, this relationship was moderated by an interaction with positive beliefs; stressful events were a stronger predictor of the extent of worry for individuals with a high level of positive beliefs than for those with a low level of positive beliefs. The moderating role of positive beliefs suggests that the level of positive beliefs amplifies the threat of worry caused by stressful events. 相似文献

The interview covers Rushton’s background in England, South Africa, and Canada, his education at the University of London (B.Sc., 1970; Ph.D., 1973), and his early research (1970–1980) on the social learning of generosity in 7- to 11-year olds. In his first book, Altruism, socialization, and society (1980), Rushton solved two “anomalies” for his social learning perspective—altruism in animals and traits in people—causing a “paradigm shift” for him toward sociobiology. He spent January to June 1981 at the University of California, Berkeley, to study the longitudinal stability of personality traits like altruism. There, he was influenced by Jensen’s work on g and race differences in rate of maturation and two-egg twinning. Subsequently, Rushton found that across 60 variables, Europeans fall between East Asians and Africans, closer to East Asians. He extrapolated Wilson’s (fast–slow) r-K life history theory to explain the pattern. Also covered is Rushton’s research on the heritability of altruism, and Genetic Similarity Theory explaining assortative mating and ethnic nepotism. Spouses and best friends are as similar as half-siblings and people randomly chosen from the same ethnic group are as related as first cousins. Altruism follows lines of similarity to replicate genes effectively. Rushton’s research on creativity is described. 相似文献

RESUMENJ. J. Aparicio presenta a D. A. Norman como uno de los representantes más cualificados de lo que se ha dado en llamar “psicología cognitiva”, siendo uno de los primeros que rompieron con la tradición de Ebbinhaus al incorporar la investigación sobre la memoria. En esta entrevista el autor responde a cuestiones tales como la relación entre sus trabajos y los del resto de psicólogos cognitivos, las limitaciones de la psicología cognitiva en sus comienzos y el papel que ha desempeñado Chomsky y la lingüística en general en el desarrollo de ésta. Seguidamente nos explica qué entiende por esquema -cuestión en la que se ha centrado últimamente- y las diferencias entre la concepción piagetiana y la suya. También comenta el concepto de profundidad de procesamiento, la distinción entre memoria episódica y semántica y el estudio del control consciente e inconsciente. La última parte de la entrevista se centra en las relaciones entre el trabajo teórico y el experimental, finalizando con algunas alusiones al camino que deben seguir los psicólogos españoles para contribuir al desarrollo de su disciplina. 相似文献

RESUMENEl hecho de las diferencias individuales en el funcionamiento mental es una realidad. Su amplitud y naturaleza tiene unas consecuencias tan importantes en nuestra cultura que hace que la sociedad demande una forma de medir la inteligencia. No obstante algunos psicólogos opinan que los tests de inteligencia son un instrumento de medida que no representa adecuadamente un modelo formal de la dinámica de los procesos de pensamiento. Este artículo consiste en una serie de argumentos teóricos y empíricos contra la separación de los tests y las teorías cognitivas. Se piensa, en este artículo, que se pueden producir substanciales beneficios del acercamiento entre el psicólogo experimental y el psicómetra; los datos disponibles indican cómo se puede producir este acercamiento. 相似文献
