The concept of conditioning as signalization proposed by Ivan P. Pavlov (1927, 1928) is studied in relation to the theory of stimulus-substitution, which is also attributed to him. In the so-called theory of stimulus-substitution a distinction must be made between an empirical principle of substitution and an actual theory of substitution, which can adopt different forms. The Pavlovian theory of substitution--which conceives substitution as a substitution of the unconditioned stimulus (US) by the conditioned stimulus (CS) in the activation of the representation of the former--can be understood as an explanation or model of signalization. Signalization and substitution are answers to different questions, and the level of analysis to which signalization corresponds, is that which concerns the nature of conditioning as an operation of the animal in the environment. 相似文献

Achieving a preventive attitude is the first step in eliminating cancer risk behaviours. This cross-sectional study evaluated the attitude towards the European Code against Cancer, in 3,031 relatives of cancer patients. The study looked for keys to improve attitude by means of educational interventions. Attitude was evaluated using a questionnaire with 63 items and a Likert's scale. Measured from -2 to +2 , the mean score was 0.905 [0.894 - 0.971]. Five per cent had a mean score under 0.38 and another 5% over 1.46. A multivariate analysis found that age, sex and level of education were significantly associated with attitude: young men with a low cultural level were those with the lowest preventive attitude. The family history of cancer was not associated with attitude. Educational interventions should modify the perceived advantages of smoking and drinking, and the disadvantages related to preventive diet and sun and workplace protection. 相似文献

Many studies have shown that IQs have been increasing over the last half century. These increases have come to be known as "the Flynn effect". The "Flynn effect" represents a difference on ability-level between groups of the same age but different cohort. The ability-level differentiation hypothesis represents a difference on the relevance of cognitive factors between groups of high and low ability. Hence, it should be possible to imitate the ability-level differentiation effect by comparing groups of the same age but different cohort. The indifferentiation hypothesis represents no differences on the relevance of cognitive abilities in all age groups within the same cohort. The aim of the present study is to test the relationships between these phenomena. For this purpose we analyzed the American standardisation samples of the WISC, WISC-R and WISC-III. Results support the link between the Flynn effect and the differentiation hypothesis. Also, reported evidence replicate previous findings supporting the indifferentiation hypothesis. Implications for the assessment of the intelligence are discussed. 相似文献

Given that studies about the differential efficacy of existing treatments in fibromyalgia syndrome are scarce, the aim of this study was to compare the differential efficacy of a cognitive-behavioral and a pharmacological therapy on fibromyalgia. Using a randomized controlled clinical trial, 28 fibromyalgic patients were assigned to one of following experimental conditions: (a) pharmacological treatment (i.e., cyclobenzaprine), (b) cognitive-behavioral intervention (i.e., stress inoculation training), (c) combined pharmacological and cognitive-behavioral treatment and (d) no treatment. The results show the superiority of cognitive-behavioral intervention to reduce the severity of fibromyalgia both at the end of the treatment and at follow-up. We conclude that cognitive-behavioral interventions must be considered a primary treatment of fibromyalgia syndrome. 相似文献

In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types
of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts.
LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries,
summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence
text). A total of 390 Spanish middle and high school students (14–16 years old) and six experts read a narrative or expository
text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments
and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository,
and LSA correlated more with human content ratings than with human coherence ratings. Finally, the holistic methods were found
to be more reliable than the componential methods analyzed in this study. 相似文献

A theoretical framework is proposed for studying minority young men's involvement with their babies that combines the integrative model of minority youth development and a life course developmental perspective with Lamb's revised four-factor model of father involvement. This framework posits a relationship between demographic and family background variables (such as education, employment, income, and family of origin) and fatherhood outcomes moderated by personal characteristics (such as sex-role ideology, acculturation, risk taking, and alienation) and mediated by definitions of fatherhood, life priorities normative for the culture under study, and sexual behavior. Once there is an acknowledged infant, a father's involvement is influenced by child characteristics, perceived fathering competence, social support, and quality of the relationship with the mother. 相似文献

Experienced athletes in sports with moving objects have shown greater skill when using visual information to anticipate the direction of a moving object than nonexperienced athletes of those sports. Studies have shown that expert athletes are more effective than novices in occlusion situations in the first stages of the sports sequence. In this study, 12 athletes with different competitive experience in sports with moving objects viewed a sequence of tennis ball launches with and without visual occlusion, launched by a ball-shooting machine toward different areas with respect to the participant's position. The relation among visual behavior, occlusion time, and the precision of the task is reviewed. The spot where the balls bounced was analysed by a digital camera and visual behavior by an Eye Tracking System. Analysis showed that the nonexperienced athletes made significantly more errors and were more variable in visual occlusion conditions. Participants had a stable visual search strategy. 相似文献

We report research investigating the role of mental models in deduction. The first study deals with conjunctive inferences (from one conjunction and two conditional premises) and disjunctive inferences (from one disjunction and the same two conditionals). The second study examines reasoning from multiple conditionals such as: If e then b; If a then b; If b then c; What follows between a and c? The third study addresses reasoning from different sorts of conditional assertions, including conditionals based on if then, only if, and unless. The paper also presents research on figural effects in syllogistic reasoning, on the effects of structure and believability in reasoning from double conditionals, and on reasoning from factual, counterfactual, and semifactual conditionals. The findings of these studies support the model theory, pose some difficulties for rule theories, and show the influence on reasoning of the linguistic structure and the semantic content of problems. 相似文献
