This study tested the hypothesis that failure in active visuospatial working memory tasks involves a difficulty in avoiding intrusions due to information that is already activated. Two experiments are described, in which participants were required to process several series of locations on a 4 × 4 matrix and then to produce only the final location of each series. Results revealed a higher number of errors due to already activated locations (intrusions) compared with errors due to new locations (inventions). Moreover, when participants were required to pay extra attention to some irrelevant (non-final) locations by tapping on the table, intrusion errors increased. Results are discussed in terms of current models of working memory functioning. 相似文献

This paper attempts to understand the interpersonal nature of bodily experience. It explores the way the body symptoms we meet in the consulting room, and in everyday life, express and communicate disturbances in our relationships with others. The article seeks to understand how others that are close to us can really get under our skins. The work of the philosopher of the body, MerleauPonty, findings from contemporary developmental psychology, recent psycho-biological studies and psychoanalytic insights are all drawn upon as a way of offering an introduction to contemporary developments in thinking and research on the body. The article explores the interdependence of body and environment. In particular, the body is always in an interpersonal context with others. Bodies are interdependent; communication is first and foremost bodily. Bodily behaviour and biological functions develop in the context of a relationship. The relationship with the other influences the formation of bodily processes and actions. Clinical examples are drawn upon to illustrate how interpersonal disturbances in development are expressed in bodily symptoms. The difference between a hysterical and psychosomatic body symptom is also briefly addressed. 相似文献

A landmark study by O'Neill (1996), in which 2-year-old children were found to be more likely to point toward a hidden object to help an adult who was unsighted during the hiding event than to point helpfully for an adult who had been sighted, seems to undermine the conventional assumption that children this young do not understand the relationship between seeing/not seeing and knowing/not knowing. Concerns remain, however, as to whether the children's success was mentalistic or behavioral. In two experiments, 2-year-old children received first-person experience with two kinds of glasses of different colors but with apparently identical opaque lenses, one of which blocked their vision and the other of which they could see through. When the parent was wearing these glasses, the children were able to use their own first-person experience of the glasses to infer whether the adult could see or not. Despite this, they did not understand the causal relationship between visual perception and knowledge formation, as demonstrated by their indiscriminate pointing behavior in response to an ignorant or a knowledgeable parent. However, in a third experiment, we examined the relationship between experience of the adult's behavioral incompetence when wearing glasses of a certain color and the children's pointing behavior. Here they tended to point appropriately. We conclude that the phenomenon reported by O'Neill (1996) yields to an account in terms of the 2-year-olds' assumptions about behavioral competence/incompetence rather than about knowledge/ignorance. 相似文献

The role of cognitions supportive of violence is acknowledged in many theories of violent behavior. Despite this, relatively little attention has been paid in research to the cognitions that contribute to violence at an individual level. The aim here was to conduct a systematic review of studies examining the impact of violence-related cognitions on non-sexual violence. Five studies were identified and these studies reported the use of five measures of violence-related cognition, namely, the EXPAGG, a Life Map, the ‘My Life’ checklist, the Provictim Scale, and the Maudsley Violence Questionnaire. The studies indicated that scales of instrumental aggression were positively related to self-reported violence in both prison and non-offender samples. Beliefs supportive of violence were also positively related to violence. This suggests that viewing aggression as means to achieve positive outcome is a risk factor for violence. By contrast, scores on an expressive aggression scale were inversely related to violence indicting that loss of control and guilt about behavior are protective factors against violence. Also, pro-victim attitudes were inversely related to violence. These scales tap the self-conscious moral emotions and recognition of these emotions may be important in violence inhibition. There is clearly a need to extend the identification of cognitions supportive of violence. This would aid research into individual-level violence and contribute to the development of effective interventions to reduce violence. 相似文献

Recent research with Rooks has demonstrated impressive tool-using abilities in captivity despite this species’ classification
as a non-tool-user in the wild. Here, we explored whether another non-tool-using corvid, the Eurasian Jay, would be capable
of similar feats and investigated the relative contributions of causal knowledge and instrumental conditioning to the birds’
performance on the tasks. Five jays were tested on a variety of tasks involving water displacement. Two birds reliably interacted
with the apparatuses. In these tasks, both birds showed a preference for inserting stones into a tube containing liquid over
a tube containing a solid or a baited ‘empty’ tube and also for inserting sinkable items over non-sinkable items into a tube
of water. To investigate the contribution of instrumental conditioning, subjects were then tested on a series of tasks in
which different cues were made available. It was found that, in the absence of any apparent causal cues, these birds showed
a clear preference for the rewarded tube when the food incrementally approached with every stone insertion, but not when it
simply “appeared” after the correct number of stone insertions. However, it was found that subjects did not prefer to insert
stones into a tube rewarded by the incremental approach of food if the available causal cues violated the expectations created
by existing causal knowledge (i.e. were counter-intuitive). An analysis of the proportion of correct and incorrect stone insertions
made in each trial across tasks offering different types of information revealed that subjects were substantially more successful
in experiments in which causal cues were available, but that rate of learning was comparable in all experiments. We suggest
that these results indicate that Eurasian jays use the incremental approach of the food reward as a conditioned reinforcer
allowing them to solve tasks involving raising the water level and that this learning is facilitated by the presence of causal
cues. 相似文献

We charted the interrelation between cognitive and motor skills in typically developing children aged 4-11 years across broad ability measures from standardized tests and investigated the nature of this relationship by examining effects of age and sex. Results indicated a significant, moderate correlation between gross cognitive and motor scores across all participants. Correlations between indices of the standardized measures and a principal component analysis revealed that visual processing (VP) and fine manual control (FMC) largely accounted for the interrelation between the overall domains. Age and sex affected the strength of gross correlation: 7-year-olds showed a weaker correlation than all other ages and females exhibited a significantly stronger correlation than males. However, the correlation between VP and FMC was constant across all age and sex groups, except 4-year-old males. These findings advance evidence that from an early age, cognitive and motor development is linked by elucidating the underlying nature of this relationship. These results have important implications for clinical, educational, and experimental practice. 相似文献

There is evidence that daily negative events at work enhance fatigue. In contrast, positive events may trigger processes that increase, but also processes that decrease, energetic resources. Accordingly, results regarding a main effect of positive events on fatigue have been mixed. However, a clearer pattern between positive events and fatigue can be expected under adverse circumstances (i.e., accumulation of negative events, high chronic stressors). Positive events may facilitate coping and accelerate recovery processes and, thus, reduce resource drain due to daily negative events and chronic stressors. Predicting fatigue in a diary study with 76 employees, we investigated interactions between daily positive events and (a) daily negative events and (b) chronic social stressors. Multilevel modeling revealed that negative but not positive events were associated with increased end-of-work fatigue. However, positive events interacted with negative events and with chronic social stressors. As expected, positive events were negatively associated with fatigue only on days with many negative events, but not so on days with few negative events. Analogously, positive events were negatively associated with fatigue only among employees with high, compared with low, chronic social stressors. We conclude that the beneficial short-term effects of positive events on energetic resources are largely confined to adverse circumstances. 相似文献

Tool making evidences intelligent, flexible thinking. In Experiment 1, we confirmed that 4- to 7-year-olds chose a hook tool to retrieve a bucket from a tube. In Experiment 2, 3- to 5-year-olds consistently failed to innovate a simple hook tool. Eight-year-olds performed at mature levels. In contrast, making a tool following demonstration was easy for even the youngest children. In Experiment 3, children’s performance did not improve given the opportunity to manipulate the objects in a warm-up phase. Children’s tool innovation lags substantially behind their ability to learn how to make tools by observing others. 相似文献
