The temptation of alternative mating partners can threaten satisfaction with and commitment to an existing romantic relationship. Consequently, people exhibit cognitive processes that help protect their relationship when faced with desirable relationship alternatives. Previous studies have focused primarily on processes that involve explicit, higher-order cognitive mechanisms such as overt judgments and choices (e.g., judging the alternative as less attractive). The current studies, in contrast, examined automatic, early-stage attentional processes that may help protect against threats posed by exposure to alternative mating partners. Whereas single participants responded to implicit mating primes by increasing early-stage attention to physically attractive opposite sex targets, participants in a committed romantic relationship were inattentive to those attractive alternatives. This research provides a novel approach for studying implicit cognitive mechanisms involved in maintaining close relationships. 相似文献

Using functional magnetic resonance imaging (fMRI) and n-back tasks we investigated whether, in 11-13-year-old children, spatial (location) and nonspatial (color) information is differentially processed during visual attention (0-back) and working memory (WM) (2-back) tasks and whether such cognitive task performance, compared to a resting state, results in regional deactivation. The location 0-back task, compared to the color 0-back task, activated segregated areas in the frontal, parietal and occipital cortices whereas no differentially activated voxels were obtained when location and color 2-back tasks were directly contrasted. Several midline cortical areas were less active during 0- and 2-back task performance than resting state. The task-induced deactivation increased with task difficulty as demonstrated by larger deactivation during 2-back than 0-back tasks. The results suggest that, in 11-13-year-old children, the visual attentional network is differently recruited by spatial and nonspatial information processing, but the functional organization of cortical activation in WM in this age group is not based on the type of information processed. Furthermore, 11-13-year-old children exhibited a similar pattern of cortical deactivation that has been reported in adults during cognitive task performance compared to a resting state. 相似文献

Participants struck 500 golf balls to a concealed target. Outcome feedback was presented at the subjective or objective threshold of awareness of each participant or at a supraliminal threshold. Participants who received fully perceptible (supraliminal) feedback learned to strike the ball onto the target, as did participants who received feedback that was only marginally perceptible (subjective threshold). Participants who received feedback that was not perceptible (objective threshold) showed no learning. Upon transfer to a condition in which the target was unconcealed, performance increased in both the subjective and the objective threshold condition, but decreased in the supraliminal condition. In all three conditions, participants reported minimal declarative knowledge of their movements, suggesting that deliberate hypothesis testing about how best to move in order to perform the motor task successfully was disrupted by the impoverished disposition of the visual outcome feedback. It was concluded that sub-optimally perceptible visual feedback evokes implicit processes. 相似文献

The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed. 相似文献

‘Internalism’ is used in metaethics for a cluster of claims which bear a family resemblance. They tend to link, in some distinctive
way—typically modal, mereological, or causal—different parts of the normative realm, or the normative and the psychological.
The thesis of this paper is that much metaethical mischief has resulted from philosophers’ neglect of the distinction between
two different features of such claims. The first is the modality of the entire claim. The second is the relation between the
items specified in the claim. In part one I explain this distinction and the problems neglecting it may cause. In part two
I show that it has been neglected, and has caused those problems, at least with respect to one version of internalism. That
is judgment internalism, which claims that moral beliefs are necessarily related to pro- or con-attitudes; e.g., that if you
believe you ought to x you must have some motivation to x. The considerations standardly adduced in favor of judgment internalism
support only a version which lacks the metaethical implications typically attributed to it, at least so far as anyone has
shown. Proponents and opponents of judgment internalism fail to realize this because of their neglect of the modality/relation
distinction. I illustrate by considering discussions of judgment internalism by Russ Shafer-Landau, Simon Blackburn, James
Dreier, David Brink, and others.

The appropriate selection of both pictorial and linguistic experimental stimuli requires a previous languagespecific standardization
process of the materials across different variables. Considering that such normative data have not yet been collected for
Modern Greek, in this study normative data for the color version of the Snodgrass and Vanderwart picture set (Rossion & Pourtois,
2004) were collected from 330 native Greek adults. Participants named the pictures (providing name agreement ratings) and
rated them for visual complexity and age of acquisition. The obtained measures represent a useful tool for further research
on Greek language processing and constitute the first picture normative study for this language. The picture norms from this
study and previous ones may be downloaded from brm.psychonomic-journals.org/content/supplemental. 相似文献

Reformers urge that representation no longer earns its explanatory keep in cognitive science, and that it is time to discard
this troublesome concept. In contrast, we hold that without representation cognitive science is utterly bereft of tools for
explaining natural intelligence. In order to defend the latter position, we focus on the explanatory role of representation
in computation. We examine how the methods of digital and analog computation are used to model a relatively simple target
system, and show that representation plays an in-eliminable explanatory role in both cases. We conclude that, to the extent
that biologic systems engage in computation, representation is destined to play an explanatory role in cognitive science.

ABSTRACT— There are signs that the debate over racial and gender differences in intelligence is about to begin again. In this article we will be concerned primarily with racial differences but will make remarks about gender differences where applicable. Previously there have been bitter arguments over whether or not races exist, over whether it is either important or proper to study racial and gender differences in intelligence, and over the conclusions that have been drawn about environmental and genetic causes as determinants of these differences. We argue that races do, indeed, exist and that studying differences in cognitive competence between groups is a reasonable thing to do. We also point out that past research on both racial and gender differences in intelligence has been marked by methodological errors and overgeneralizations by researchers on all sides of the issue. We propose ten principles of design, analysis, and reporting that ought to be considered carefully when doing or evaluating research in this area. 相似文献

Relations among body image satisfaction and social comparisons to either same-sex peers or media models were examined in 2 studies of adolescent boys and girls. In the first study, 9th and 10th graders described their conceptions of attractiveness for same- and opposite-sex adolescents. These attractiveness attributes were then used in Study 2 in which 7th- and 10th-grade boys and girls reported on social comparisons to models/celebrities and same-sex peers. Body dissatisfaction was also assessed. The results confirmed that both same-sex peers and models/celebrities were the targets of social comparisons for physical attributes, but comparisons on personal and social attributes were more likely directed toward same-sex peers. For boys and girls, weight comparisons to both peer and model targets were primary correlates of body dissatisfaction. In addition, shape comparisons reported by the girls and facial comparisons endorsed by the boys also related to body dissatisfaction. Gender differences in social comparison indicated that girls reported more social comparisons across targets and attributes. Results are discussed in terms of the role of social comparison and peer context for body image during adolescence. 相似文献
