Methodologically and theoretically based on metarrepresentational deficit hypothesis, we design an intervention to teach the mental state of pretense to an autistic boy. The production and comprehension of symbolic play by means of the use of two specific strategies founded on pictorial analogy of the mental representation and process, was the focus of the learning. The efficiency and efectiveness of the program is reflected in the results that indicated the subject's competence to generate and comprehend the pretense as well as to generalize the acquired knowledge into other areas of mentalistic functioning. We discuss the possibility to develop a metarrepresentational knowledge based on the internalizing of the strategies of conceptual support. 相似文献

A crucial demand in dual tasks suffering from a capacity limited processing mechanism is task-order scheduling, i.e. the control of the order in which the two component tasks are processed by this limited processing mechanism. The present study aims to test whether the lateral prefrontal cortex (LPFC) is associated with this demand. For this, 15 participants performed a psychological refractory paradigm (PRP) type dual task in an event-related functional magnetic resonance (fMRI) experiment. In detail, two choice reaction tasks, a visual (response with right hand) and an auditory (response with left hand), were presented with a temporal offset of 200 ms, while the participants were required to respond to the tasks in the order of their presentation. Importantly, the presentation order of the tasks changed randomly. Based on previous evidence, we argue that trials in which the present task order changed as compared to the previous trial (different-order trials) impose higher demands on task coordination than same-order trials do. The analyses showed that cortical areas along the posterior part of the left inferior frontal sulcus as well as the right posterior middle frontal gyrus were more strongly activated in different-order than in same-order trials, thus supporting the conclusion that one function of the LPFC for dual-task performance is the temporal coordination of two tasks. Furthermore, it is discussed that the present findings favour the active scheduling over the passive queuing hypothesis of dual-task processing. 相似文献

We have previously proposed that cortical auditory-vocal networks of the monkey brain can be partly homologized with language networks that participate in the phonological loop. In this paper, we suggest that other linguistic phenomena like semantic and syntactic processing also rely on the activation of transient memory networks, which can be compared to active memory networks in the primate. Consequently, short-term cortical memory ensembles that participate in language processing can be phylogenetically tracked to more simple networks present in the primate brain, which became increasingly complex in hominid evolution. This perspective is discussed in the context of two current interpretations of language origins, the "mirror-system hypothesis" and generativist grammar. 相似文献

The main determinants of lexical access in speech are considered to be a word's age of acquisition (AoA) and its frequency of occurrence in a speaker's experience. It is unclear whether and how these variables interact, although they are commonly observed to be correlated, for the few studies that address the issue have reported inconsistent findings. An influential view of AoA in lexical processing (Ellis and Lambon Ralph, 2000) predicts stronger frequency effects for items acquired later in life than for those acquired at an early age. Five experiments were designed to investigate the possible interaction of AoA and frequency effects in speech. We found that the interaction between word frequency and AoA was not robust and that, contrary to expectation, the effect of word frequency was greater for words acquired earlier in life than for those acquired later. The implications of our findings are discussed. 相似文献

This study investigated the trait emotional intelligence (trait EI or trait emotional self‐efficacy) profiles of 512 students from five university faculties: technical studies, natural sciences, social sciences, arts, and humanities. Using the Trait Emotional Intelligence Questionnaire, it was hypothesised that (a) social sciences would score higher than technical studies in Emotionality, (b) arts would score higher than technical studies in Emotionality, (c) arts would score lower than technical studies in Self‐control, and (d) there would be an interaction between gender and faculty, whereby female students would score higher than male students within the social sciences only. Several other exploratory comparisons were also performed. Results supported hypotheses (a), (b), and (d), but not hypothesis (c), although the differences were in the predicted direction. 相似文献

In this article I describe the sources of my indigenous theology out of my own experiences, my worldview, and as a woman. In the first part, I mention our struggles of resistance as the source from which we draw our strength and hopes to resist oppression and dream of a different society, as our ancestors dreamed and acted. I then speak of our living for the day as an act of ideological resistance. It is possible that many readers do not yet understand it, but this involves a worldview different from that of Western capitalism. Some communities in the Amazon still practise this other worldview and take it as their guide. They live day by day, concerned not for the morrow but for the present day; they attempt to live a life of quality, justice and honesty, as if it were the last day of their lives. The source from which our theological enterprise springs is also our wise men and women, who still survive in our communities. They are the guardians of our ancestral wisdom on life, the cosmos and our relations with the created world and its creatures. Moreover, our lifestyle is based on caring for and protecting Pachamama as one of the joint creators with God, who offers us life and enables us to live in the world as brothers and sisters, because we come into being in Pachamama and return to her. 相似文献

This study assessed whether two well known effects associated with cognitive control, conflict adaptation (the Gratton effect) and conflict context (proportion congruent effects), reflect a single common or separate control systems. To test this we examined if these two effects generalized from one kind of conflict to another by using a combined-conflict paradigm (involving the Simon and Spatial Stroop tasks) and manipulating the proportion of congruent to incongruent trials for one conflict (Simon) but not the other (Spatial Stroop). We found that conflict adaptation effects did not generalize, but the effect of conflict context did. This contrasting pattern of results strongly suggests the existence of two separate attentional control systems, one transient and responsible of online regulation of performance (conflict adaptation), the other sustained and responsible for conflict context effects. 相似文献
