Do 14- to 17-month-olds notice the paths and manners of motion events? English- and Spanish-learning infants were habituated to an animated motion event including a manner (e.g., spinning) and a path (e.g., over). They were then tested on four types of events that changed either the manner, the path, both, or neither component. Both English- and Spanish-learning infants attended to changes of manner and changes of path. Thus, infants from two different language communities proved sensitive to components of events that undergird relational term learning. 相似文献

Adding an upright inner square frame to an outer tilted square frame causes a central rod's perceived orientation to be directionally opposite the usual rod-and-frame illusion (RFI). Zoccolotti, Antonucci, Daini, Martelli, and Spinelli (1997) attributed this double RFI (DRFI) to Rock's (1990) hierarchical organization principle. In Experiment 1, this explanation predicted results for small (11 degrees ) but not larger (22 degrees and 33 degrees ) outer frame orientations. In two experiments with the DRFI, bottom-up, goal-driven attention was varied and direct and indirect measures of the framework's influence were compared. In Experiment 2, the RFI angular function was compared with two other DRFI conditions: a direct measure of perceived rod orientation and an indirect measure of the inner frame. These conditions induced directionally opposite effects. In Experiment 3, direct and indirect measures of the inner frame's perceived tilt were compared. Angular functions differing in size and direction were obtained. Experiment 4 replicated the previous results, using a different psychophysical procedure. All the results were consistent with the hierarchical organization mechanism but suggested different processing strategies due to different attentional weights. They were also consistent with other recent findings based on the Bayesian approach to accounts of illusory phenomena (e.g., Jazayeri & Movshon, 2006, 2007; Weiss, Simoncelli, & Adelson, 2002). 相似文献

Any theory of language must account for how children learn verbs, the gateway to grammar. Yet verbs can be difficult to learn. Building on Gentner's 'natural partitions hypothesis' we suggest that, to learn a verb, infants must conceptualize components of events and map verbs in the ambient language onto those components. Although toddlers detect and categorize at least some of the conceptual underpinnings of verb categories, the mapping of verbs onto these representations is not transparent. Mapping is a difficult problem in its own right. The Emergentist Coalition Model that has been used to explain noun learning also begins to explain how children move from perceptual to social and then to linguistic information to link verbs to actions and events. 相似文献

Each person is perceived by others and by herself as an individual in a very strong sense, namely as a unique individual. Moreover, this supposed uniqueness is commonly thought of as linked with another character that we tend to attribute
to persons (as opposed to stones or chairs and even non-human animals): a kind of depth, hidden to sensory perception, yet in some measure accessible to other means of knowledge. I propose a theory of strong or essential individuality. This theory is introduced by way of a critical discussion of Van Inwagen’s and Baker’s ontologies of persons. Composition
Theory and Constitution Theory are shown to be complementary, in their opposite strong and weak points. I argue that both
theories have unsatisfactory consequences concerning personal identity, a problem which the proposed theory seems to solve
more faithfully both to folk intuitions and the phenomenology of personal life.

This study tested a broad array of determinants of smoking grounded in general social psychological theories, as well as personality and social development theories. Using data from 2,004 middle school students, all proximal and distal determinants significantly predicted smoking in the hypothesized direction. Further, hierarchical logistic regressions showed that intention to smoke, positive and negative attitudes toward smoking, impediments to smoking, self‐efficacy to resist smoking, parent norms, and academic success most strongly predicted current smoking. Hierarchical linear regressions suggested that parental relatedness, maladaptive coping strategies, depression, and low academic aspirations most strongly predicted susceptibility to smoking for those who had not yet smoked a cigarette. Global expectancies were the strongest predictor of susceptibility in low socioeconomic status students. These findings may guide the development of future theory‐based interventions that produce the greatest reductions in youth smoking. 相似文献

The consensus of several studies on health among Gulf War (GW)-deployed veterans is that they have elevated symptom complaints. Central nervous system (CNS) symptoms among these veterans have been assessed in several investigations. Studies have disagreed as to whether there are neuropsychological deficits in GW-deployed veterans relative to controls. When differences between these groups have been found, they have often been attributed to stress or psychiatric factors, although exposures to neurotoxic substances present in the GW theatre have also been indicted as possible explanations. A review of the existing literature as well as the 5 papers contained in this issue of Journal of Psychopathology and Behavioral Assessment suggests that the neuropsychological and health symptom sequelae of GW zone service are multidetermined and cannot easily be explained on the basis of simplistic models of causation. Psychological, historical, and exposure parameters must be considered in the scientific evaluation of this problem. 相似文献

When walking without vision, people mentally keep track of the directions and distances of previously viewed objects, a process called spatial updating. The current experiment indicates that while people across a large age range are able to update multiple targets in memory without perceptual support, aging negatively affects accuracy, precision, and decision time. Participants (20 to 80 years of age) viewed one, three, or six targets (colored lights) on the floor of a dimly lit room. Then, without vision, they walked to a target designated by color, either directly or indirectly (via a forward turning point). The younger adults’ final stopping points were both accurate (near target) and precise (narrowly dispersed), but updating performance did degrade slightly with the number of targets. Older adults’ performance was consistently worse than the younger group, but the lack of interaction between age and memory load indicates that the effect of age on performance was not further exacerbated by a greater number of targets. The number of targets also significantly increased the latency required to turn toward the designated target for both age groups. Taken together, results extend previous work showing impressive updating performance by younger adults, with novel findings showing that older adults manifest small but consistent degradation of updating performance of multitarget arrays. 相似文献

THE PERCEIVED IMPORTANCE OF DEVELOPMENTAL RELATIONSHIPS ON WOMEN UNDERGRADUATES' PURSUIT OF SCIENCE 总被引:1,自引:0,他引:1

Using a survey of women science majors, we tested the assumption that women mentors and other women guides help women students pursue the sciences. The survey explicitly distinguished among three types of guides: mentors (who provide psychosocial support), sponsors (who provide instrumental support), and role models (who act as examples) encountered before and during college. We found that over 90% of the women had a guide of one type or another, that mentors were most influential to women's pursuit of science, and that guides during college were more influential than guides prior to college. Participants reported having more female than male guides overall, but that some of the most influential guides were men. 相似文献

A model of career engagement is presented to help bridge the gap between career counselors' focus on supporting individuals to find meaningful work and employers' desire for an engaged, productive, and committed workforce. 相似文献
