Motion onset captures attention 总被引:4,自引:0,他引:4
Although visual motion may seem salient, motion per se does not automatically attract attention. We show here, however, that the onset of motion does indeed attract attention. In three experiments, subjects identified target letters in displays that contained targets and distractors. There was no advantage for moving letters among static ones, but there was an advantage for objects that had recently started to move despite the fact that the motion was uninformative. If some additional time was allowed to elapse after motion onset, inhibition of return slowed responding to the item that had started to move—a further sign that the motion onset had captured attention. Finally, detection of target letters was found to be independent of the number of distractors in the display if the target had undergone motion onset, also indicative of attentional capture. We discuss the adaptive significance of sensitivity to onsets in the presence of a relative insensitivity to ongoing motion. 相似文献

Personality traits predict substance use in adolescence, but less is known about prospective substance use in middle age and beyond. Moreover, there is growing interest in how personality change and the multiplicative effects among personality traits relate to substance use. Participants included approximately 4000 adults aged 25-74 who participated in two waves of the Midlife in the US (MIDUS) study. Higher levels of neuroticism, extraversion, openness, and lower levels of conscientiousness and agreeableness predicted longitudinal substance use. Increases in neuroticism and openness predicted increased substance use while increases in conscientiousness and agreeableness predicted decreased substance use. Higher levels of conscientiousness moderated two of the other trait main effects. Personality, trait change, and interactions among traits reliably forecasted 10-year substance-use behaviors. 相似文献

Intellectualist theories attempt to assimilate know how to propositional knowledge and, in so doing, fail to properly explain
the close relation know how bears to action. I develop here an anti-intellectualist theory that is warranted, I argue, because
it best accounts for the difference between know how and mere “armchair knowledge.” Know how is a mental state characterized
by a certain world-to-mind direction of fit (though it is non-motivational) and attendant functional role. It is essential
of know how, but not propositional knowledge, that it makes possible performance errors and has the functional role of guiding
action. The theory is attractive, in part, because it allows for propositional, non-propositional and perhaps even non-representational
varieties of know how. 相似文献

As newborn screening (NBS) technology expands, genetic counselors will become more involved in counseling for NBS results, including those potentially generated from whole exome sequencing (WES) and eventually whole genome sequencing (WGS). Members of the National Society of Genetic Counselors (NSGC) responded to an online survey (n?=?208) regarding genomic counseling in the context of NBS. The majority of participants (82.1 %) did not feel prepared to counsel for WGS results from NBS. Counselors with previous WES/WGS counseling experience felt more prepared (p?=?0.005) to counsel for WGS results from NBS than those without WES/WGS experience. Overall, counselors expressed ethical and practical concerns regarding WGS in NBS, as well as a need for additional training regarding this application of the technology before it is implemented. Based on the results of this study, genetic counselors voice caution to the larger genetics community regarding expansion of NBS to incorporate genomic sequencing and advocate for additional education prior to initiating WGS into NBS. 相似文献

Naturalists who conceive of knowledge as a natural kind are led to treat ‘knowledge’ as a natural kind term. ‘Knowledge,’ then, must behave semantically in the ways that seem to support a direct reference theory for other natural kind terms. A direct reference theory for ‘knowledge,’ however, appears to leave open too many possibilities about the identity of knowledge. Intuitively, states of belief count as knowledge only if they meet epistemic criteria, not merely if they bear a causal/historical relation to the term. I will develop this objection and show that it is grounded in modal considerations central to Kripke’s work on reference. I will also argue that a more plausible externalist semantics for natural kind terms disarms the objection. 相似文献

The past two decades have seen a tremendous surge in scientific interest in the extent to which certain types of training—be it aerobic, athletic, musical, video game, or brain trainer—can result in general enhancements in cognitive function. While there are certainly active debates regarding the results in these domains, what is perhaps more pressing is the fact that key aspects of methodology remain unsettled. Here we discuss a few of these areas including expectation effects, test–retest effects, the size of the cognitive test battery, the selection of control groups, group assignment methods, difficulties in comparing results across studies, and in interpreting null results. Specifically, our goal is to highlight points of contention as well as areas where the most commonly utilized methods could be improved upon. Furthermore, because each of the sub-areas above (aerobic training through brain training) share strong similarities in goal, theoretical framework, and experimental approach, we seek to discuss these issues from a general perspective that considers each as members of the same broad “training” domain. 相似文献

In two visual world eye tracking studies, we examined the activation of subordinate meanings of ambiguous homophones in Hindi and particularly when the sentence context is biased towards the dominant meaning. Participants listened to sentences that were either neutral or biased towards the dominant meaning of the homophone and saw a display containing four pictures. In experiment 1, the display had a shape competitor of the subordinate meaning of the homophone in both neutral and biased conditions along with three unrelated distractors. Experiment 2 had semantic competitors of the subordinate meaning of the homophones along with three distractors. Proportion of fixations to different objects overtime suggested that participants activated the subordinate meanings and oriented their attention to the shape and semantic competitors even when the prior context was biased towards the dominant meaning. Overall, these data from Hindi provide further support to those models of lexical access that assume exhaustive access of both the meanings of an ambiguous homophone. These data suggest even a dominant bias does not eliminate the activation of perceptual and conceptual features of the subordinate meaning. 相似文献
