Abstract

In the Social Contract Rousseau gives what could be called a philosophical rule of recognition for law in Modernity: a law is law if and only if ‘the whole people rules over the whole people’. Thus, he defines self-legislation as, at bottom, collective intentional action. I will first map out the speech act structure [LEX] underlying self-legislation on this account. In particular, I argue for a first person plural counterpart of the reflexive structure inherent to intentions generally: the notion of a collective self. Then I take issue with Bratman's analysis of shared intentional activity in terms of mutuality, submitting that it misses out on the specifically political presupposition involved in ‘doing something together’. I will show why ‘mutuality’ requires representation of the unity of a polity, and how this representation can take form without either external authority or mutual responsiveness.  相似文献

Spatial attention can be biased to locations near the hand. Some studies have found facilitated processing of targets appearing within hand-grasping space. In this study, we investigated how changing top-down task priorities alters hand bias during visual processing. In Experiment 1, we used a covert orienting paradigm with nonpredictive cues and emphasized the location of the hand relative to the target. Hands or visual anchors (boards) were placed next to potential target locations, and responses were made with the contralateral hand. Results indicated a hand-specific processing bias: Hand location, but not board location, speeded responses to targets near the hand. This pattern of results replicated previous studies using covert orienting paradigms with highly predictive cues. In Experiment 2, we used the same basic paradigm but emphasized the location of the response hand. Results now showed speeded responses to targets near response locations. Together these experiments demonstrated that top-down instructional sets (i.e., what is considered to be most relevant to task performance) can change the processing priority of hand location by influencing the strength of top-down, as compared with bottom-up, inputs competing for attention resources.  相似文献

Although a substantial body of research exists concerning the patterns of causal attributions that are made to explain achievement outcomes, relatively little attention has been paid to the effects that measurement techniques have on the attributions they elicit. Two methodological factors—question-wording style and research context—were hypothesized to affect the results of attribution studies. Participants made informational (e.g., "How hard did you try?") and causal (e.g., "To what extent was effort a cause of your outcome?") attributions to outcomes in either an experimental (anagram-task) or natural (classroom-examination) research context. Significant outcome effects were found for (a) informational but not causal attributions to ability and to the task and for (b) attributions to ability in the natural but not in the experimental context. The implications of these findings for attribution theory and research are discussed.  相似文献

Coss (1991a) found that squirrels from populations that differed in their historical exposure to snakes reacted in a manner similar to that of squirrels sympatric with snakes when exposed to one; lab-reared pups also showed some typical reactions to a snake. Coss concluded that the squirrels possessed a genetic relic of the pattern of behavior typical of the common progenitor at a time when snakes exerted selection pressure on squirrel evolution. It is argued here that this concept of behavioral relics is suspect and should be employed with caution. The concept is difficult to apply rigorously, and the philosophy of the concept is diametrically opposed to the animal-environment mutualism espoused by ecological psycholo- gists. Three more parsimonious explanations for the phenomena reported in Coss (199 1 a) are suggested.  相似文献

The cohesive energy of Fe as a function of structure, strain and magnetic state has been computed using the full potential linearized augmented-plane-wave method within the framework of density functional theory and the generalized gradient approximation. Calculations corresponding to uniaxial stress in the <100> direction reveal that the ideal tensile strength of bcc Fe is about 14.2GPa and is determined by instability with respect to transformation into an unstable ferromagnetic fcc structure. The low-energy fcc phase is a modulatedantiferromagnetic fcc structure that is connected to the bcc phase via a first-order magnetic transformation and does not compromise its ideal strength.  相似文献

Is visual awareness graded or binary? Experimental work has provided support for both possibilities, leading to two coexisting but contradictory theoretical accounts. Here we propose a promising candidate factor through which to integrate both accounts: the depth of stimulus processing required by the task. We compared color identification (a low-level task) with numerical judgements (a high-level task) performed on the very same colored number stimuli. Psychophysical curves were analyzed for both objective discrimination performance and subjective visibility ratings on a trial-by trial basis. We observed a graded relationship between stimulus duration and visibility in the low-level task, but a more non-linear relationship in the high-level task. Both patterns of results have previously been consistently associated with the graded and the dichotomous account, respectively. Follow-up experiments that manipulate the level of processing can further unify previously inconsistent results, thus integrating two major theories of visual awareness.  相似文献

The authors evaluated an intervention program developed to remediate children's deficits in reading emotions in facial expressions. Thirty children from 2 elementary schools in suburban Atlanta participated in 6 30-min sessions over 4 weeks in which they were taught to discriminate, identify, express, and apply facial expression cues. The ability to read emotion in facial expressions significantly improved for the intervention group compared with the control group. Improvement on identifying facial expressions was associated with increased feelings of lower social anxiety and higher self-worth for girls. Boys' self-concept was negatively related to improvement. On the basis of the results, the authors suggested that structured interventions like the present one could be used to improve students' nonverbal processing abilities within public school settings, but with some cautions regarding the impact of new learning for boys.  相似文献

The study examined the effects of gender and item content of domain‐general and domain‐specific creative‐thinking tests on four subscale scores of creative‐thinking (fluency, flexibility, originality, and elaboration). Chinese tenth‐grade students (234 males and 244 females) participated in the study. Domain‐general creative thinking was measured by using two domain‐independent items—box and newspaper. Domain‐specific creative thinking was measured in the domain of history by two history‐specific items—school uniform and health food—that were part of lessons in modern Chinese history. Domain‐general creative‐thinking scores were not different across gender in any of the four subscales. In domain‐specific creative thinking, female students produced more responses (fluency) and more categories of ideas (flexibility), and more detailed answers (elaboration) on both items than did males. Gender difference was not found in originality. Item effects were significant in both general and specific creative‐thinking scores, with higher fluency, flexibility, and elaboration for the newspaper than the box item, and higher fluency, flexibility, originality, and elaboration for the school uniform than the health food item. The findings on both gender and item effects support the contention that personal interest and life experience influence the generation of creative solutions. The finding that gender did not differ in domain‐general creative‐thinking was expected, as the two general items (box and newspaper) are experienced similarly by both genders. As most of the creative‐thinking tests are influenced by individuals' experience beyond creative‐thinking ability, judicial evaluation and use of creative‐thinking scores are underscored.  相似文献

The authors aimed to examine the possible association between (a) accurately reading emotion in facial expressions and (b) social and academic competence among elementary school-aged children. Participants were 840 7-year-old children who completed a test of the ability to read emotion in facial expressions. Teachers rated children's social and academic behavior using behavioral rating scales. The authors found that children who had more difficulty identifying emotion in faces also were more likely to have more problems overall and, more specifically, with peer relationships among boys and with learning difficulties among girls. Findings suggest that nonverbal receptive skill plays a significant role in children's social and academic adjustment.  相似文献

This research proposes a two-dimensional measure of engagement for professionals in technically-oriented workgroups. It examines the relationship of their engagement to five workgroup outcomes: innovation, performance, satisfaction with the organization, career success, and intentions to stay. Three studies are reported involving: (1) a random sample of 123 workgroups and 1351 self and reports by others of professionals employed by a Fortune 100 company, (2) a panel study of 1024 of the study one professionals four months later, and (3) the replication of results with 827 professionals across three cultures. The results support felt engagement and behavioral engagement as distinct constructs that can be measured by both a self-report and assessments by others of workgroup engagement. The relationship of engagement to workgroup innovation, performance, satisfaction with the organization, career success, and intentions to stay generalized across four countries and cultures: U.S./North America, The Netherlands/Europe, Argentina, and India. Felt engagement was the best predictor of affective outcomes and intentions to stay when all variables were measured concurrently. Behavioral engagement was the best predictor of workgroup performance concurrently and over time. This research indicates that the two dimensions of engagement are important aspects of vocational adjustment for the success of professionals in technically-oriented workgroups. Implications for future research are to consider multiple dimensions of engagement, clearly define the population and setting for engagement, and to study engagement as a dynamic experience that warrants ongoing management and workgroup attention.  相似文献
