In “ A Light Theory of Color”, Walter Sinnott-Armstrong and David Sparrow argue that color is neither a primary quality of
objects, nor a disposition that objects have, nor a property of our visual fields. Rather, according to the view they present,
color is a property of light. The present paper aims to show, first, that the light theory is vulnerable to many of the very
same objections that Sinnott-Armstrong and Sparrow raise against rival views. Second, the paper argues that the strategies
that Sinnott-Armstrong and Sparrow use to avoid certain objections are also available to proponents of rival accounts. This
might only seem to show that the light theory is in the same shaky boat as other theories: suffering from the same problems
but having the same tools for solving them. The paper concludes with a suggestion as to why this is not the case, but why
the existence of the light theory is nevertheless likely to bring increased clarity to the debate about color realism. 相似文献

Following terror management theory, the authors suggest women's striving to attain a thin physique is fueled in part by existential concerns. In three studies, women restricted consumption of a nutritious but fattening food in response to reminders of mortality (mortality salience; MS). When conducted in private (Study 1), this effect was found among women but not men; when replicated in a group setting in which social comparison was likely (Studies 2 and 3), only women who were relatively less successful attaining the thin ideal (i.e., high body mass index; BMI) restricted eating after MS. In Study 3, MS caused high BMI women to perceive themselves as more discrepant from their ideal thinness; this perceived failure mediated the effects of MS and BMI on eating behavior. Findings are discussed from a self-regulatory framework, which considered in the context of pressures for women to be thin, can shed light on health risk behavior. 相似文献

The Academic and Behavioral Competencies (ABC) Program, a schoolwide program to reduce classroom disruption and encourage rule following, academic task completion, and homework completion, is described. The program was initially developed and implemented in an elementary school with a high-risk population. Data from teachers, parents, and children indicate high levels of satisfaction with the program. In addition, unobtrusive measures of program impact, reported as reductions in referrals to the principal's office, suspensions, and increases in homework completion rates relative to the year prior to implementation of the program, suggest a preliminary positive impact of the program. A replication is reported for another school district, with teacher evaluations of satisfaction and effectiveness reported, supporting the flexibility and adaptability of the program. Although the present article does not constitute a systematic evaluation of the ABC Program, it presents preliminary data on the process of implementation and stakeholder satisfaction. 相似文献

It is widely recognized that people sometimes use theory-of-mind judgments in moral cognition. A series of recent studies shows that the connection can also work in the opposite direction: moral judgments can sometimes be used in theory-of-mind cognition. Thus, there appear to be cases in which people's moral judgments actually serve as input to the process underlying their application of theory-of-mind concepts. 相似文献

ProtoMatch is a software tool for integrating and analyzing fixed-location and movement eye gaze and cursor data. It provides
a comprehensive collection of protocol analysis tools that support sequential data analyses for eye fixations and scanpaths
as well as for cursor “fixations” (dwells at one location) and “cursorpaths” (movements between locations). ProtoMatch is
modularized software that integrates both eye gaze and cursor protocols into a unified stream of data and provides an assortment
of filters and analyses. ProtoMatch subsumes basic analyses (i.e., fixation duration, number of fixations, etc.) and introduces
a method of objectively computing the similarity between scanpaths or cursorpaths using sequence alignment. The combination
of filters, basic analyses, and sequence alignment in ProtoMatch provides researchers with a versatile system for performing
both confirmatory and exploratory sequential data analyses (Sanderson & Fisher, 1994). 相似文献

This research examined whether stereotype vulnerability-the tendency to expect, perceive, and be influenced by negative stereotypes about one's social category-is associated with uncertainty about one's academic self-knowledge in two important ways. We predicted that stereotype-vulnerable African American students would (a) know less about how much they know than less vulnerable students do and (b) have unstable academic efficacy. In Study 1, Black and White participants took a verbal test and indicated the probability that each of their answers was correct. As expected, stereotype-vulnerable Black participants were more miscalibrated than other participants. In Study 2, participants completed measures of self-efficacy twice daily for 8 days. Also as expected, the academic efficacy of stereotype-vulnerable Blacks fluctuated more-and more extremely-than that of other participants. The results suggest that, in addition to undermining intellectual performance, stigma interferes with academic self-knowledge. 相似文献

The number, amplitude, duration, and bout structure of isolation-induced ultrasonic vocalization (USV) of infant rats (Rattus norvegicus) were measured on postnatal Day 10. Measurements were made before and after a brief, 1-min, active interaction with their mother or before and after a "pick-up" control procedure. Consistent with prior studies, the number of USVs emitted was significantly increased in the period following the maternal reunion but not after the control procedure. The average amplitude of USVs was also greater following maternal reunion. Finally, analyses characterizing the bout structure of USV production indicated that the average bout size (i.e. number of USVs/bout) was increased severalfold following the reunion with the mother, accounting for the greater rate of USV production during the second isolation period. 相似文献

In several recent studies, saccadic eye movements were found to be influenced by concurrent reaching movements. The authors investigated whether that influence originates in limb kinematic or kinetic signals. To dissociate those 2 possibilities, the authors required participants (N = 6) to generate pointing movements with a mass that either resisted or assisted limb motion. With practice, participants were able to generate pointing responses with very similar kinematics but whose kinetics varied in a systematic manner. The results showed that saccadic output was altered by the amount of force required to move the arm, consistent with an influence from limb kinetic signals. Because the interaction occurred before the pointing response began, the authors conclude that a predictive signal related to limb kinetics modulates saccadic output during tasks requiring eye-hand coordination. 相似文献
