In section 1 we argue that the adoption of a tenseless notion of truth entails a realistic view of propositions and provability. This view, in turn, opens the way to the intelligibility of theclassical meaning of the logical constants, and consequently is incompatible with the antirealism of orthodox intuitionism. In section 2 we show how what we call the potential intuitionistic meaning of the logical constants can be defined, on the one hand, by means of the notion of atemporal provability and, on the other, by means of the operator K of epistemic logic. Intuitionistic logic, as reconstructed within this perspective, turns out to be a part of epistemic logic, so that it loses its traditional foundational role, antithetic to that of classical logic. In section 3 we uphold the view that certain consequences of the adoption of atemporal notion of truth, despite their apparent oddity, are quite acceptable from an antirealist point of view. 相似文献

In a cross-sectional study of 83 unmedicated boys, 6 to 16 years of age (M = 10.6, SD = 2.1), attending public (N = 48) and therapeutic schools for behaviorally disturbed children (N = 35), we examined relations of externalizing psychopathology to age-dependent change in performance on cognitive and motivational dimensions of impulse control assessed by laboratory tasks. When we controlled for internalizing symptoms and IQ or school achievement, all children showed improving competence with increasing age on both dimensions over the age range of the sample. Children with externalizing problems performed more poorly on both dimensions at all ages than children without such problems. Comparing age-dependent competence for the two groups, a model of convergent maturation in cognitive aspects of impulse control, and a model depicting a stable deficit in motivational aspects of impulse control in those children with externalizing behavior problems, relative to those without such problems, emerged. Studies of individual growth in impulse control, together with correlates of growth, are needed to validate these observations.Project on Human Development in Chicago Neighborhoods 相似文献

Sensitivity to Affective Information and Investors' Evaluation of Past Performance: An Eye‐tracking Study 下载免费PDF全文
In the present work, we used the eye‐tracking methodology to investigate how affective reactions influence investment decision making. In addition, we looked at individual differences in terms of people's sensitivity to affective information and how efficiently they regulate it, that is, trait emotional intelligence. We demonstrated that people who are more sensitive to affective information have larger pupil dilation when looking at the past performance of a stock fund. In addition, we also found that participants' larger pupil dilation had an impact on their investment decisions (whether people were more likely to sell their shares, hold on to the investment, or buy more shares). A larger pupil dilation led people to be more consistent and willing to invest more money on a fund regardless from its past performance (positive or negative). We also tested the hypothesis that individuals with a larger pupil dilation should be more influenced by a fund's past performance (e.g., selling their shares more often when the past performance of the fund was negative and buying additional shares more often when the past performance was positive). However, results did not support this explanation. Finally, our data revealed that the effect of individual differences in trait emotional intelligence on investment decisions was significantly mediated by pupil dilation. In the discussion, we explored the relationship between our results and previous evidence on the role of pupil dilation in processing information under uncertainty and the role of affect in decision making.

Different basic emotions (anger, fear, disgust, happiness, sadness, and surprise) are consistently associated with distinct bodily sensation maps, which may underlie subjectively felt emotions. Here we investigated the development of bodily sensations associated with basic emotions in 6‐ to 17‐year‐old children and adolescents (n = 331). Children as young as 6 years of age associated statistically discernible, discrete patterns of bodily sensations with happiness, fear, and surprise, as well as with emotional neutrality. The bodily sensation maps changed from less to more specific, adult‐like patterns as a function of age. We conclude that emotion‐related bodily sensations become increasingly discrete over child development. Developing awareness of their emotion‐related bodily sensations may shape the way children perceive, label, and interpret emotions. 相似文献

The Dutch book argument is a coherence condition for the existence of subjective probabilities. This paper gives a general framework of analysis for this argument in a nonadditive probability setting. Particular cases are given by comonotonic and affinely related Dutch books that lead to Choquet expectations and Min expectations. 相似文献

In this study we tested the hypothesis that fear might facilitate learning when experienced contextually to the task. To this purpose, learning and memory performance of CD-1 mice in a Morris Water Maze (MWM) was assessed in the presence of a live predator (rat). Results indicate that a live predator induced specific predatory-avoidance responses, such as diving behavior and thigmotaxis. The rat-exposed group showed the most adaptive strategy, balancing anti-predator behavior and escape responses, while the rat pre-exposed group showed impairment in the initial phases of the acquisition. The probe trial revealed distinct swimming patterns but equal memory abilities in the different groups. Overall, this procedure represents a novel and easy test to assess the effects of stressful stimuli, contextually to spatial learning and memory performance, in mice. 相似文献

AbstractThis study investigates the interplay between family risk and the quality of classroom interactions and their impact on self-regulation skills in two groups of children—children from socioeconomically disadvantaged backgrounds (at-risk) and non-risk children. Participants included 485 children (N = 93 classrooms)—233 (N = 47 classrooms) of which were from socioeconomically disadvantaged areas. Temperament was measured using teacher report. Trained observers rated classroom quality via live observations of a typical preschool day. Behavioral regulation was assessed using direct measures and emotional regulation was assessed using a teacher report. Analyses using multiple group structural equation modeling showed that at-risk children had lower levels of cool behavior regulation than non-risk children. In addition, classroom quality was positively linked to cool behavioral self-regulation. Moderating effects were additionally found between family risk and classroom quality on both hot behavioral regulation and emotional regulation. Classroom quality served as a protective factor for children exposed to more risk factors. Results showed complex associations between individual characteristics, classroom quality, and family risk, indicating a need to further explore the interplay among these variables. 相似文献

Seven healthy subjects underwent functional magnetic resonance imaging (fMRI) of the brain while performing an inspection time task. Employing a block-type design, the task had three difficulty levels: a control condition, an easy (200 ms stimulus duration), and a more difficult (40 ms) discrimination. Based on group results, there were widespread significant areas of difference in brain activation and deactivation when pairwise comparisons were conducted among the three task conditions. When the difficult condition was compared with the easy condition, there was relative activation in areas of the following brain regions: cingulate gyrus and some frontal and parietal lobe areas. Areas within the following regions showed relative deactivation (greater blood oxygenation level-dependent, BOLD, signal in the easy condition): frontal, temporal, and parietal lobe. There were overlaps between these areas and those found to be active while performing higher cognitive tasks in other functional brain imaging studies. These pilot data encourage future studies of the functional anatomy of inspection time and its relevance to psychometric intelligence. 相似文献
