Outside the cognitive psychologist's laboratory, problem-solving is an activity that takes place in a rich web of interactions involving people and artefacts. This interactivity is constituted by fine-grained action–perception cycles, and it allows a reasoner's comprehension of the problem to emerge from a coalition of internal and external resources. Taking an ecological approach to problem-solving, this paper introduces a qualitative method, Cognitive Event Analysis, for studying the fine-grained interactivity between a problem-solving agent and his/her environment. To demonstrate the potential of this method, it is used to study a single subject solving the so-called 17 Animals problem using a material model. The fine-grained procedure allows tracking the solution to a serendipity that was brought about because of the participant's aesthetic considerations and a change in her perceptual figure-ground configuration. While a qualitative single-case method cannot prove specific models of problem-solving, it questions prevalent mentalist models, and it generates new hypotheses on insight problem-solving, because it allows the researcher to attend to outliers and to variability on a fast and fine-grained between-measurement timescale.  相似文献

We offer the new software Codex, written in Visual Basic 3.0. It is a tool adequate in observational methodology. Its fundamental objective is to record motor and verbal behavior using the data types proposed by Bakeman and Quera (1995, 1996), together with the field formats proposed by Hall (1963), Weick (1968), Hutt and Hutt (1974), and Anguera (1979). It is designed to allow for data interchange between specific programs in use in observational methodology (SDIS-GSEQ, The Observer, and Theme) and other general programs (spread sheets, statistics applications, word processing programs, sound cards, etc.).  相似文献

Remarks On Quantum Ontology   总被引:2,自引:0,他引:2  
Krause  Décio 《Synthese》2000,125(1-2):155-167
Despite the discrepancies between quantum objects and `classical' ones, mainly with regard to the fact that the latter may be thought of as `individuals', contrary to the former, we still regard the quanta as `things' in our ordinary discourse as well as in the logico-mathematical basis of quantum theories. This paper considers some possibilities for accomodating the logico-mathematical framework of the theories which deal with such a strange ontology where the inhabitants are things devoid of identity and both having and not having certain properties.``All right', said the Cat; and this time it vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone.``Well! I've often seen a cat without a grin', thought Alice, ``but a grin without a cat! It's the most curious thing I ever saw in all my life!'Lewis Carroll  相似文献

The current study examined the relationship between childhood anxiety and threat perception abnormalities. Children (N = 105) were exposed to stories reflecting three types of anxiety: social anxiety, separation anxiety, and generalized anxiety. From children's reactions to the stories, a number of threat perception indices were derived. Children's level of anxiety was assessed by means of questionnaires and a structured diagnostic interview. Results indicated that high levels of anxiety, as measured by questionnaires and interview, were accompanied by a high frequency of threat perception, high ratings of threat, a high frequency of threatening interpretations, high levels of negative feelings and cognitions, and an early detection of threat. Furthermore, results seemed to suggest that threat perception abnormalities were mediated by children's general level of anxiety rather than by levels of specific anxiety symptoms.  相似文献

Routley-Meyer type relational complete semantics are constructed for intuitionistic contractionless logic with reductio. Different negation completions of positive intuitionistic logic without contraction are treated in a systematical, unified and semantically complete setting.  相似文献

Recent research on brain activity suggests that visual attention increases in response to emotional images. This increase is reflected in signs of greater activity, in response to different emotional visual stimuli, in parietal and parietooccipital areas in several studies employing neuroimaging techniques and event-related potentials (ERPs). In the latter case, greater parietal and parietooccipital negativities have been observed. The objective of the present study was to examine the role of a person's level of motivation towards the emotional stimulus with respect to this ERP pattern. Two groups of stimuli were presented to 60 participants: neutral or N (photographs of taps) and appetitive or A (photographs of cakes). The level of hunger was measured via a questionnaire. Recordings were taken at PO3, PO4, P7, and P8. The largest differences, as a function of appetite, were produced between 575 and 625 ms. Multiple regression analyses were carried out to study the relationship between subjects' appetite and their ERP recordings in response to A and N stimuli. There was a significant negative association between appetite and 575–625 mean amplitude in response to stimulus A at PO3 and PO4.  相似文献

According to the age differentiation hypothesis (ADH), g becomes increasingly invested in specific abilities with age: with increasing age, g should account for a decreasing proportion of the variance in any particular cognitive test. However, there is no conclusive evidence concerning this important topic. Data from the Italian, Spanish, and American standardisation samples of the WPPSI and the WISC-R were analysed in the present study for testing the ADH. No changes in the proportion of variance associated with g in the 4–16 age range were found. This pattern does not change depending on the country. Therefore, the ADH is rejected: g seems to be very stable across age, and, thus, it seems to be an equally important component of intelligence test performance from early childhood to late adolescence.  相似文献

A study is reported which examined the impact of repressive coping style on processing and recalling information about rape. It was predicted that repressors selectively avoid threatening information about a rape incident and that selective avoidance is reflected in poorer recall for details of the rape account as well as anticipation of fewer coping problems in the event of sexual victimization. A total of N=143 women were presented with an authentic rape scenario taken from police files. The sample was divided into repressors, sensitizers, non‐anxious and defensive high‐anxious individuals on the basis of an anxiety and a social desirability measure. Differential memory by the four groups for the rape scenario was measured in a free‐recall task. In addition, respondents were asked to anticipate potential coping problems they thought they would experience in the event of sexual victimization, and they were asked to indicate their behavioural precautions against a sexual assault. As predicted, repressors showed poorer recall for the described rape than both sensitizers and non‐anxious subjects. Results were less conclusive concerning the proposed interaction of anxiety and defensive avoidance on anticipated coping problems. No effect was found of cognitive coping style on behavioural precautions against rape. The findings are discussed with respect to the construct validity of repression as a cognitive strategy for coping with threat in the domain of sexual violence.

Alexithymia refers to the difficulties an individual has in experiencing and expressing feelings. The 20‐item Toronto Alexithymia Scale (TAS‐20) and the Bermond–Vorst Alexithymia Questionnaire (BVAQ) with two parallel versions of 20 items have been constructed to measure it. The present study compared the psychometric properties of these two self‐report questionnaires in English (N=290) and French (N=322) language versions. Confirmatory factor analysis was used to examine the fit between the hypothesized factors and the data. Results revealed a better fit to the data for the second version of the BVAQ (BVAQ‐20B) for both language versions as compared to the TAS‐20, the whole BVAQ, or the first version of the BVAQ (BVAQ‐20A). Additionally, the factor comparison of both language versions indicated that only the factorial structure of the BVAQ‐20B was replicable across languages. Concurrent validity of the questionnaires is discussed. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献
