The aim of the present study was to determine whether monitoring measures are differentially disturbed in dysexecutive patients after frontal lesions. Twelve dysexecutive patients and 12 healthy controls were administered a paired-associates learning task. Their performances on recall prediction, judgment-of-learning (JOL), and feeling-of-knowing judgment (FOK) were then compared. The results revealed that the two groups differed only on accuracy measures of the FOK paradigm. The study of the overall correlations between the three measures of metamemory revealed a significant relation between recall prediction and accuracy measures of the JOL. We failed to find any significant correlation with the accuracy measures of the FOK. Taken together, our data confirm that metamemory experience is not a unitary construct but rather a group of distinct and quite independent mechanisms. 相似文献

The aim of the present study was to determine how interhemispheric collaboration and visual attention in basic lexical tasks develop during early childhood. Two- to 6-year-old children were asked to name two different pictures presented simultaneously either one in each visual hemifield (bilateral condition) or both in a single hemifield (either right or left, unilateral condition). In the bilateral condition, children were overall more accurate in naming right visual field than left visual field pictures. This difference was significant for 2- and 3- to 4-year-old children, but not for 5- to 6-year-old children. These results show that the right and left cerebral hemispheres do not develop naming competencies equally well in early childhood. A second analysis, based on the order of report, showed that when 2- and 3- to 4-year-old children named both the left and the right visual field pictures, they named the right visual field picture first. In contrast, at the age of 5-6 years, children named the left visual field picture first and overall naming performance reached a ceiling level. Several interpretations are proposed to explain this shift of visual attention at the age of 5-6 years. In the unilateral condition, no difference was found between naming accuracy in the right and left visual fields, presumably because interhemispheric pathways are functional: visual stimuli presented to the right hemisphere can be processed by the most competent left hemisphere without degradation of information. This result confirms previous findings on the development of interhemispheric collaboration. 相似文献

We examined interference effects of emotionally associated background colours during fast valence categorisations of negative, neutral and positive expressions. According to implicitly learned colour–emotion associations, facial expressions were presented with colours that either matched the valence of these expressions or not. Experiment 1 included infrequent non-matching trials and Experiment 2 a balanced ratio of matching and non-matching trials. Besides general modulatory effects of contextual features on the processing of facial expressions, we found differential effects depending on the valance of target facial expressions. Whereas performance accuracy was mainly affected for neutral expressions, performance speed was specifically modulated by emotional expressions indicating some susceptibility of emotional expressions to contextual features. Experiment 3 used two further colour–emotion combinations, but revealed only marginal interference effects most likely due to missing colour–emotion associations. The results are discussed with respect to inherent processing demands of emotional and neutral expressions and their susceptibility to contextual interference. 相似文献

An increasing number of studies are investigating the cognitive processes underlying human–object interactions. For instance, several researchers have manipulated the type of grip associated with objects in order to study the role of the objects’ motor affordances in cognition. The objective of the present study was to develop norms for the types of grip employed when grasping and using objects, with a set of 296 photographs of objects. On the basis of these ratings, we computed measures of agreement to evaluate the extent to which participants agreed about the grip used to interact with these objects. We also collected ratings on the dissimilarity between the grips employed for grasping and for using objects, as well as the number of actions that can typically be performed with the objects. Our results showed grip agreements of 67 % for grasping and of 65 % for using objects. Moreover, our pattern of correlations is highly consistent with the idea that the grips for grasping and using objects represent two different motor dimensions of the objects. 相似文献

Tight frequency-to-amplitude relationships are observed in spontaneous human steady gait. They can be modified, if required; that flexibility forms a fundamental basis of the intentional adaptive capabilities of locomotion. In the present experiments, the processes underlying that flexibility were investigated at both the level of joint kinematics and the level of neuromuscular synergies. Subjects (N = 4) walked at the same speed either with a preferred or a nonpreferred frequency-to-amplitude relationship (i.e., constrained, short steps at a high frequency [COS condition] or constrained, long steps at a low frequency [COL condition]); their swing and stance phases were separately analyzed. In the COS condition, increases in EMG activity were specifically required during the swing phase. In the COL condition, several muscles required increases in EMG activity during the stance phase, but decreases of the hamstring muscles were needed during the swing phase. Whereas, in preferred walking, modification of the frequency affects the EMG patterns globally (the gain increasing with the frequency in both the stance and swing phases), the present results show that changing the frequency in a constrained manner either affects the swing phase specifically or affects both phases, but in the opposite direction. That finding indicates mat a separate control is needed in both the swing and the stance phases. 相似文献

This study investigated the relations between perceived autonomy support from three significant sources (parents, friends, and the romantic partner) and university students’ subjective well-being (SWB) using two approaches: a variable-centered and person-centered approach. Participants were 256 university students (191 women, 65 men) involved in a romantic relationship. Results from both approaches revealed that students’ perception that significant individuals support their autonomy predicted higher levels of SWB. Furthermore, results from a person-centered approach suggested that students reported the highest levels of SWB when all sources were perceived to be highly autonomy supportive. Together, these findings support a sensitization process of need satisfaction. Implications for SWB and self-determination theory are discussed. 相似文献

It is now a fact that health and well being at work are enhanced by organizational characteristics (Dupret, Bocéréan, Teherani, & Feltrin, 2012) and individual characteristics such as coping strategies used in a stressful situation (Truchot & Fisher, 2002). The purpose of this research is to study the interaction between organizational characteristics and coping strategies in the emergence of psychosocial risks factors. This study was conducted with 427 employees, as part of a psychosocial risk assessment. The analysis (Sobel tests and LISREL modelization) show the moderating influence between coping strategies and the organizational variables on occupational health and life quality. 相似文献

The impact of the presentation format of covariation information on causal judgements was examined in a fictitious virus-disease causal induction task. Six different judgement conditions were created by crossing two levels of virus-disease covariation (0, .5) with three levels of disease base rate (.25, .5, .75). The covariation information was presented differently to three groups of participants. In a first group, it was presented in propositional format summarising the frequencies of the four patient types, namely patients with or without the virus who either did have or did not have the disease. In a second group the same information was presented in a 2×2 table with the cell frequencies represented in terms of countable objects (the presence/absence of virus/disease was shown as schematic faces that varied in expression and colour). In a third group the covariation information was presented in terms of a cumulative frequency tree with the two main branches representing the frequencies of patients with and without the disease which further decomposed into subgroups of those with and without the virus. The ability to discriminate between the levels of covariation was poorest in Group 1; it was significantly improved in Group 2, and was best in Group 3. These results suggest that the format with which covariation information is presented to reasoners exerts a significant influence on causal judgements. 相似文献

The 2-4-6 rule discovery task introduced by Wason (1960) elicits generally poor hypothesis-testing behaviour as reflected by the underwhelming effort and creativity participants invest in the process before announcing their “best” guess. The traditional task departs from real-world hypothesis testing in a significant respect: Reasoners proceed to discover the rule solely from an internal representation of the problem space. Two studies reported here examined representational effects in the 2-4-6 task by developing task isomorphs that offered external, physically manipulable, representations of the dimensions of the problem space. These isomorphs led to a significantly higher incidence of successful rule discovery, driven by significantly greater diligence and creative exploration of the problem space, compared to other task isomorphs that did not offer such an external representation. These results confirm the fruitfulness of a research programme that explores the contextual determinants of sound hypothesis testing. 相似文献
