Two experiments explored the existence and the development of relations between action representations and object representations. A priming paradigm was used in which participants viewed an action pantomime followed by the picture of a tool, the tool being either associated or unassociated with the preceding action. Overall, we observed that the perception of an action pantomime can facilitate the recognition of a corresponding tool. Experiment 1 was based on a naming task and was conducted with 9- to 12-year-old children and a group of young adults. While substantial priming effects were obtained for all age groups, they were especially important for the youngest participants. Smaller priming effects were obtained in Experiment 2, using a categorization task and conducted on 5- to 11-year-old children and young adults, but again the results suggest that these action priming effects diminish with increasing age. Implications of these results for the organization and development of conceptual knowledge are discussed. 相似文献

The topic of this paper is phenomenology. How should we think of phenomenology – the discipline or activity of investigating experience itself – if phenomenology is to be a genuine source of knowledge? This is related to the question whether phenomenology can make a contribution to the empirical study of human or animal experience. My own view is that it can. But only if we make a fresh start in understanding what phenomenology is and can be. 相似文献

Joint attention is often referred to as a triadic relation between self, other and object. Young children with autism show
deficiencies in the use of joint attention behaviors. Individual differences may be expected, and they may be determined by
the children’s cognitive development or the characteristics of the relationship of the child with the caregiver. Although
most joint attention skills develop under the age of three, most studies of joint attention in children with autism involved
children older than 3 years of age, due to difficulties in diagnosing autism under this age. In this study we investigated
joint attention behaviors of 78 young children (mean age 25.7 months, SD 6.1) with autism spectrum disorders (n = 20), other developmental delays (n = 18), and typically developing children (n = 40). Following the pertinent literature and confirmed by factor analysis, two types of joint attention behaviors were distinguished,
Basic Joint Attention (BJA) and Associated Joint Attention (AJA). We found that cognitive delays and autistic symptoms—but
not attachment insecurity or disorganization—were related to less joint attention. Already at the age of 2 years, children
with more autistic symptoms show less joint attention, even after controlling for developmental level. 相似文献

Humans apply complex conceptual judgments to point-light displays (PLDs) representing biological motion (BM), but how animals process this kind of display remains uncertain. Four baboons (Papio papio) were trained to discriminate BM from nonbiological motion PLDs using an operant computerized test system. Transfer tests were given after training with novel BM stimuli representing humans or baboons (Experiment 1), with inverted PLDs (Experiment 2), and with BM stimuli in which body parts had been spatially disorganized (Experiment 3). Very limited transfer was obtained with the novel and inverted displays in Experiments 1 and 2, but transfer was much higher after spatial disorganization in Experiment 3. It is suggested that the baboons did not retrieve and interpret the articulated shape of the human or monkey body from the BM PLD stimuli, but rather focused their attention on the configural properties of subparts of the stimuli. Limits in perceptual grouping and restricted abilities in picture-object equivalence might explain why the baboons did not map BM PLD displays onto what they represent. 相似文献

Most explanations of social influence focus on why individuals might want to agree with the opinions or attitudes of others. The authors propose a different explanation that assumes the attitudes of others influence only the activities and objects individuals are exposed to. For example, individuals are likely to be exposed to activities that their friends enjoy. The authors demonstrate that such influence over sampling behavior is sufficient to produce a social influence effect when individuals form attitudes by learning from experience. Even if the experiences of 2 individuals, when they sample an object or event, are independent random variables, their attitudes will become positively correlated if their sampling processes are interdependent. Interdependent sampling of activities thus provides a different explanation of social influence with distinct empirical and theoretical implications. 相似文献

Two experiments were conducted to examine how activation of the motivational systems of approach and withdrawal (arm flexion vs. extension) through 2 different bodily mechanisms (right arm vs. left arm) influenced participants' evaluations of neutral Chinese ideographs. Study 1 found that unilateral flexion on the right side and unilateral extension on the left side led to more positive evaluations than unilateral flexion on the left side and unilateral extension on the right side. Using bilateral movements, Study 2 found that simultaneous performance of a right-arm flexion and a left-arm extension led to more positive evaluations than a left-arm flexion and a right-arm extension. A motor congruence hypothesis was offered to account for these findings. 相似文献

The significant increase in IQ in the industrialised countries during recent decades, known as the eponymous Flynn Effect, tends to be given numerous explanations (progress in schooling, television, nutrition, etc.). One way of studying this effect consists of assessing in which subtests the change in IQ takes place. Using the comparison among 120,000 French children on an intelligence test in 1965 and the results of 8640 children on the same test in 1988, Greenfield's hypothesis is discussed: that television and other media using graphical representations have induced an improvement in spatial and visual capacities to the detriment of capacities relating to vocabulary. The results are compatible with Greenfield's hypothesis, although other explanations are still possible. 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

Comparison of textual analysis applied to two lectures written three years apart by one author: the language satellites 总被引:1,自引:0,他引:1
A comparative textual analysis was carried out on two essays "Thanatol" and "Double Talk," by F. Perrier, which were originally lectures given three years apart by the author, a psychoanalyst. This study involved the use of the ALCESTE software program, a computer-assisted method of discourse analysis. It consists of modelling the distribution of the main words occurring in speeches or texts with a view toward identifying the repetitive language patterns most frequently used by a speaker or writer. This method is described in the first part of the paper. Various types of discourse emerged from analysis along with specific topics. There were three types in the case of Thanatol and four in that of Double Talk. Upon comparing the separate results obtained on each corpus, a pool of significant words observed in the corpus Thanatol was also present in Double Talk. These words were organised into groups called "language satellites" which were dispatched in the various types of discourse. Considering the underlying language structure (the enunciation), they formed another discourse running between the lines of two lectures. This supplementary discourse was recurrent and could be said to label the author and his thoughts. The ALCESTE method brings to light in the textual production of an author a recurrent pattern of discourse which might hold some clues for the analysis of texts and speech and even about the author as evident in his own ideas and thoughts. 相似文献
