The evident power and utility of the formal models of logic and mathematics pose a puzzle: Although such models are instances of verbal behavior, they are also essentialistic. But behavioral terms, and indeed all products of selection contingencies, are intrinsically variable and in this respect appear to be incommensurate with essentialism. A distinctive feature of verbal contingencies resolves this puzzle: The control of behavior by the nonverbal environment is often mediated by the verbal behavior of others, and behavior under control of verbal stimuli is blind to the intrinsic variability of the stimulating environment. Thus, words and sentences serve as filters of variability and thereby facilitate essentialistic model building and the formal structures of logic, mathematics, and science. Autoclitic frames, verbal chains interrupted by interchangeable variable terms, are ubiquitous in verbal behavior. Variable terms can be substituted in such frames almost without limit, a feature fundamental to formal models. Consequently, our fluency with autoclitic frames fosters generalization to formal models, which in turn permit deduction and other kinds of logical and mathematical inference. 相似文献

A cross-sectional study using children aged 3 to 7 years and a cross-sequential study using children aged between 5 and 8 years showed that the development of phonological recoding in working memory was more complex than the simple dichotomous picture portrayed in the current literature. It appears that initially children use no strategy in recall, which is proposed to represent the level of automatic activation of representations in long-term memory and the storage capacity of the central executive. This is followed by a period in which a visual strategy prevails, followed by a period of dual visual-verbal coding before the adult-like strategy of verbal coding finally emerges. The results are discussed in terms of three working memory models (Baddeley, 1990; Engle, 1996; Logie, 1996) where strategy use is seen as the development of attentional processes and phonological recoding as the development of inhibitory mechanisms in the central executive to suppress the habitual response set of visual coding. 相似文献

Abstract Sixty male Vietnam combat veterans, 30 hospitalized for post-traumatic stress disorder (PTSD) and 30 with no PTSD or other psychiatric disorder, sorted and labeled their life events into numeric matrices (repertory grids). Through hierarchical-classes analysis of a subject's matrix, we could compare the hierarchical level (elaboration) of the subject's constructs of a negative combat event with the hierarchical levels of other subjects' constructs of negative combat events and with the subject's precombat life event construction. As predicted, the level of construct elaboration was virtually identical for the two groups for precombat non-trauma-related events but was reduced in the PTSD group for the negative combat event. In addition, the Pythagorean distance scores of the PTSD group indicated less conceptual distance between the negative combat event and negative life events after Vietnam compared with the non-PTSD group's scores. Patients with PTSD rated negative life events more extremely (fewer “shades of gray” ratings) than did the non-PTSD group, especially life events that occurred after Vietnam. 相似文献

ABSTRACTThe present study examined the relationship between religiosity and competitive anxiety in college athletes and whether there were differences in competitive anxiety for intrinsically religious and extrinsically religious individuals. College athletes (N?=?95) from three separate sports from the NCAA completed a questionnaire that included the Age-Universal I/E Scale, the Competitive State Anxiety Inventory-2 Revised, open-ended questions on habits related to religion, and demographic items. Results revealed no significant relationship between intrinsic and extrinsic religiosity and competitive anxiety. Extrinsically religious athletes had higher somatic anxiety than intrinsically religious athletes. The majority of participants (77%) reported praying before games primarily for comfort. Athletes turn to religion to calm their nerves but it is important to understand that their approach to religion may relate to increased anxiety. This information is useful for sport practitioners and coaches as they seek to help their athletes seek an intrinsic approach to religion in sport. 相似文献

Unconscious stimuli can influence participants’ motor behavior but also more complex mental processes. Recent research has gradually extended the limits of effects of unconscious stimuli. One field of research where such limits have been proposed is spatial cueing, where exogenous automatic shifts of attention have been distinguished from endogenous controlled processes which govern voluntary shifts of attention. Previous evidence suggests unconscious effects on mechanisms of exogenous shifts of attention. Here, we applied a cue-priming paradigm to a spatial cueing task with arbitrary cues by centrally presenting a masked symmetrical prime before every cue stimulus. We found priming effects on response times in target discrimination tasks with the typical dynamic of cue-priming effects (Experiments 1 and 2) indicating that central symmetrical stimuli which have been associated with endogenous orienting can modulate shifts of spatial attention even when they are masked. Prime–Cue Congruency effects of perceptual dissimilar prime and cue stimuli (Experiment 3) suggest that these effects cannot be entirely reduced to perceptual repetition priming of cue processing. In addition, priming effects did not differ between participants with good and poor prime recognition performance consistent with the view that unconscious stimulus features have access to processes of endogenous shifts of attention. 相似文献

Multilevel analysis is an appropriate tool for the analysis of hierarchically structured data. There may, however, be reasons to ignore one of the levels of nesting in the data analysis. In this article a three level model with one predictor variable is used as a reference model and the top or intermediate level is ignored in the data analysis. Analytical results show that this has an effect on the estimated variance components and that standard errors of regression coefficients estimators may be overestimated, leading to a lower power of the test of the effect of the predictor variable. The magnitude of these results depends on the ignored level and the level at which the predictor variable varies, and on the values of the variance components and the sample sizes. 相似文献

Current knowledge about the relationship between psychological characteristics and metabolic syndrome (MetS) components is limited in Asian populations. The purpose of this study is to investigate linkages between physiological markers of MetS and life satisfaction, hostility, and depression in Chinese adults. Secondary analyses were conducted using cross-sectional data from parents of randomly selected middle school students participating in a pilot study in Qingdao, China. Among 440 parents who consented to participate (237 women, 203 men), 368 provided valid responses in all three categories of psychological characteristics, and only those subjects were included in these analyses. General linear models and logistic regressions were run separately by gender, controlling for covariates. Among women, life satisfaction was inversely associated with triglyceride levels (p = .04), LDL-C (p < .01), risk of hypertriglyceridemia (OR[.53], p < .01), HDL-C (OR[.78], p = .03), and MetS (OR[.52], p = .03). No associations were found between life satisfaction and any psychological characteristics among men. Among women, hostility was positively associated with triglyceride level (p = .04) and risk of hypertriglyceridemia (OR[2.12], p < .05). Among men, hostility was positively associated with waist circumference (p = .04), waist-hip ratio (p < .05), and fasting plasma insulin (p < .01). Depression was not associated with any physiological measurement in either gender. These findings indicate that relationships exist between certain psychological characteristics and physiological indicators of MetS among Chinese adults, although there may be important differences between genders. 相似文献

According to the principle of alternative possibilities (PAP), a person is morally responsible for what he has done only if he could have done otherwise. In what follows, I want to defend this principle against an apparent counterexample offered recently by Derk Pereboom (Living without free will, 2001; Midwest Studies in Philosophy, 29:228?C247, 2005). Pereboom??s case, a variant of what are known as ??Frankfurt cases,?? is important for it attempts to overcome a dilemma posed for earlier alleged counterexamples to PAP. However, I will argue that by paying closer attention to the details of Pereboom??s example, we see that his example fails to show a way between the horns of the dilemma posed for the earlier Frankfurt examples. 相似文献

Many visual search experiments measure response time (RT) as their primary dependent variable. Analyses typically focus on mean (or median) RT. However, given enough data, the RT distribution can be a rich source of information. For this paper, we collected about 500 trials per cell per observer for both target-present and target-absent displays in each of three classic search tasks: feature search, with the target defined by color; conjunction search, with the target defined by both color and orientation; and spatial configuration search for a 2 among distractor 5s. This large data set allows us to characterize the RT distributions in detail. We present the raw RT distributions and fit several psychologically motivated functions (ex-Gaussian, ex-Wald, Gamma, and Weibull) to the data. We analyze and interpret parameter trends from these four functions within the context of theories of visual search. 相似文献
