Using the dot task (see Jones, Farrand, Stuart, & Morris, 1995)--regarded as a good visuospatial analogue of the verbal serial recall task--we examined whether the Hebb repetition effect and its characteristics can be extended to visuospatial material. Classically, the Hebb effect has been associated with serial verbal memory: Repetition of a to-be-remembered sequence of verbal items every third trial markedly improves serial recall of that sequence. In the present study, Hebb effects were observed with visuospatial information, and a direct comparison between verbal and spatialsequence learning revealed that the Hebb repetition effect for visuospatial information shares similar characteristics with its verbal analogue. Our results cast some doubt regarding the parsimony of the view that the classical verbal Hebb effect is driven by a store specialized for phonological information and impose some further constraints on modeling serial memory and implicit sequence learning. 相似文献

The goal of this study was to examine the links between difficult temperament (i.e., negative emotionality) and harsh parental discipline during toddlerhood, and reactive and proactive aggression in kindergarten. These links were assessed on a longitudinal population-based study of 1516 boys and girls followed longitudinally from the age of 17 months through the age of 72 months. Two possible models were tested to examine the interplay between negative emotionality and harsh parenting in predicting later reactive aggression compared to proactive aggression. The first was an additive model where both aspects make unique contributions in predicting later reactive aggression. The second model was an interactive model where harsh parenting exacerbates the link between negative emotionality and reactive aggression. Results showed a specific contribution of negative emotionality to reactive aggression. The results relative to harsh parenting are more mixed but nonetheless in line with developmental models stressing different pathways to reactive and proactive aggression. 相似文献

Developmental trajectories of childhood disruptive behaviors and adolescent delinquency: a six-site,cross-national study 总被引:37,自引:0,他引:37

This study used data from 6 sites and 3 countries to examine the developmental course of physical aggression in childhood and to analyze its linkage to violent and nonviolent offending outcomes in adolescence. The results indicate that among boys there is continuity in problem behavior from childhood to adolescence and that such continuity is especially acute when early problem behavior takes the form of physical aggression. Chronic physical aggression during the elementary school years specifically increases the risk for continued physical violence as well as other nonviolent forms of delinquency during adolescence. However, this conclusion is reserved primarily for boys, because the results indicate no clear linkage between childhood physical aggression and adolescent offending among female samples despite notable similarities across male and female samples in the developmental course of physical aggression in childhood. 相似文献

Lexical decision times and eye movements were recorded to determine whether grammatical gender can influence the visual recognition of isolated French nouns. This issue was investigated by assessing the use of two types of regularities between a noun's form and its gender--namely ending-to-gender regularities (e.g., the final letter sequence -at appears only in masculine nouns and, thus, is predictive of masculine gender) and gender-to-ending regularities (e.g., feminine gender would predict the final letter e, whereas masculine gender would not). Previous studies have shown that noun endings are used by readers when they have to identify gender. However, the influence of ending-to-gender predictiveness has never been investigated in a lexical decision task, and the effect of gender-to-ending regularities has never been evaluated at all. The results suggest that gender information can influence both the activation stage (Experiments 1 and 3) and the selection stage (Experiments 2 and 3) of the word recognition process. 相似文献

The attentional blink (AB) corresponds to a transient deficit in reporting the second (T2) of two targets embedded in a rapid sequence of distractors. The retrieval competition (Shapiro, Raymond & Arnell, 1994) and bottleneck models (Chun & Potter, 1995; Jolicoeur, 1998) predict the attenuation of the deficit with the extension of the delay between T2 and its mask. This prediction was tested using auditory sequences of nonverbal stimuli in which the T2-mask interval was systematically varied. The magnitude of the auditory AB diminished with the lengthening of the interval from 50 to 150 ms while no time-locked deficit was observed with the longest (350 ms) and the shortest (10 ms) intervals. These results suggest that presenting a mask after T2 is not sufficient to produce an auditory AB: The mask must be perceivable as an auditory event distinct from the target and occur before T2 consolidation. The present study also provides evidence that as in vision, AB deficits take place in the auditory domain when T2 is masked by interruption but not by integration. Our findings are best accounted for in terms of bottlenecked processing limitations. 相似文献

According to , pronounced left hemisphere lateralization for language abilities in women, as in female absolute right-handers, limits their right hemisphere capacity and spatial abilities. This study examines the degree of handedness and the family history of non-right-handedness with respect to real-life spatial abilities in women. Twenty-four women had, first, to learn a new route and, second, to orient themselves within a labyrinth. In the former task, the number of errors and completion time were evaluated; in the latter task, degree of error for orienting was recorded. The results show that, contrary to Annett's prediction, right-handers with and without a family history of non-right-handedness did not differ on these measures. In addition, and unexpectedly, absolute right-handers were found to surpass non-absolute ones in the spatial orientation task. These findings do not support Annett's hypothesis and are discussed in relation to functional cerebral organization. 相似文献

The impact of broadband noise on serial memory: changes in band-pass frequency increase disruption 总被引:5,自引:0,他引:5
Irrelevant sound consisting of bursts of broadband noise, in which centre frequency changes with each burst, markedly impaired short-term memory for order. In contrast, a sequence of irrelevant sound in which the same band-pass noise burst was repeated did not produce significant disruption. Serial recall for both visual-verbal (Experiment 1) and visual-spatial items (Experiment 2) was sensitive to the increased disruption produced by changing irrelevant noise. The results provide evidence that sounds that are largely aperiodic can produce marked disruption of serial recall in a similar manner to periodic sounds (e.g., speech, musical streams, and tones), and thus show a changing-state effect. 相似文献

This article presents a group-based method to jointly estimate developmental trajectories of 2 distinct but theoretically related measurement series. The method will aid the analysis of comorbidity and heterotypic continuity. Three key outputs of the model are (a) for both measurement series, the form of the trajectory of distinctive subpopulations; (b) the probability of membership in each such trajectory group; and (c) the joint probability of membership in trajectory groups across behaviors. This final output offers 2 novel features. First, the joint probabilities can characterize the linkage in the developmental course of distinct but related behaviors. Second, the joint probabilities can measure differences within the population in the magnitude of this linkage. Two examples are presented to illustrate the application of the method. 相似文献

Le premier tractatus du commentaire d'Albert le Grand à l'Isagoge de Porphyre consiste en une manière de proème ou d'introduction à l'ensemble de la logique. Comme la plupart des textes d'Albert le Grand, ce traité est d'une très grande richesse, qu'atténuent toutefois son manque d'ordre et son obscurité d'expression. Étant donné que les aspects fondamentaux de la logique y sont touchés—son statut scientifique et philosophique, son utilité, son sujet, sa division, sa relation aux sciences du langage, etc.—, ce petit ouvrage est du plus haut intérêt pour quiconque cherche à mieux comprendre la logique et la philosophie de la logique du XIIIe siècle. L'auteur présente ici une traduction annotée et expliquée de ce texte difficile, faite d'après la version provisoire de la nouvelle édition de Cologne. Le relevé des sources principales de l'ouvrage révèle, sur un fond aristotélicien permanent, une forte influence des traités logiques arabes nouvellement arrivés en Occident. The first tractatus of Albert the Great's commentary on Porphyry's Isagoge consists of a kind of proem or introduction to the whole of logic. As most of Albert the Great's texts, this tract is of great richness, though it lacks order and is sometimes obscure. Since the fundamental themes of logic are addressed therein—its scientific and philosophical status, its utility, its subject, its division, its relation to the linguistic arts, etc.—, this small work is of high interest for anyone trying to better understand thirteenth-century logic and philosophy of logic. The author presents a translation of this difficult text, made after a preliminary version of the new critical edition and enriched with an introduction and explanatory notes. The survey of the main sources of the tract reveals, apart from a permanent artistotelian background, the strong influence of the Arabic logical treatises which were then coming in the Western world. 相似文献

The aim of this study is to broaden our understanding of the construction and early decline of spatial mental representations in route learning, considering the extent to which spatial ability and age-related differences in environment learning interact. The experiment examines spatial mental representation derived from taking a realistic route acquired using virtual environment and compares individuals different in age but with similar spatial ability. A sample of 34 young (20–30 years) and 30 middle-aged (50–60 years) females with good mental rotation ability were chosen. Participants learned a complex route through its presentation in a virtual environment and then performed a series of tasks (landmark recognition, location of landmarks and verification of spatial relations). Results show that the two participant age groups had similar performance in landmark recognition task and in verification of sentences describing direct spatial relations; instead, the middle-aged group showed a poorer performance than younger in their ability to locate landmarks and to judge the truth of indirect spatial sentences. These results first suggest that spatial abilities have to be seriously considered to avoid any confusion with age, as age-related differences are attenuated when individuals are different in age but similar in spatial ability. Second they confirm a specific difficulty of older participants to handle spatial information in a global configuration. 相似文献
