Healy (1994) and Koriat and Greenberg (1994) offered different theoretical accounts of the missingletter effect (MLE) in the letter-detection task, whereby a disproportionate number of letter-detection errors occur in frequent function words. Healy emphasized identification processes, whereas Koriat and Greenberg viewed the structural role of the embedding word to be crucial. Recent research suggests that neither position alone can account for the complete set of observations pertaining to the MLE. The present paper offers a theoretical integration of these competing explanations of letter detection in terms of a GO (guidance-organization) model of reading. This model specifies how structural processing of connected text helps guide eye movements to semantically informative parts of the text, enabling readers to achieve on-line fluency.  相似文献

In this paper the refinement and psychometric properties of the Infant–Toddler Social and Emotional Assessment (ITSEA) are described. Results from a sociodemographically diverse birth cohort sample of 1,235 parents of children between the ages of 12 and 36 months are presented. Confirmatory factor analyses supported the hypothesized Internalizing, Externalizing, Regulatory, and Competence domains as well as the 17 individual scales that comprise the ITSEA. Findings for 3 additional indices useful in identifying significant psychopathology are presented. Subgroup analyses revealed structural invariance and expected mean level differences across both child sex and 6-month age bands. Child sex differences emerged for some problem and most competence scales, with boys rated as higher on Activity–Impulsivity and girls rated higher on Anxiety and most Competence scales. All competence scores increased across age groups. Problem behaviors showed a more mixed developmental pattern. Test–retest and interrater reliability were acceptable. Associations between the ITSEA and independent evaluator ratings and parental ratings of child behavior problems, temperament, and parental distress support the validity of the instrument.  相似文献

We propose the term 'Venus effect' for a common phenomenon in picture perception. It occurs when a picture shows an actor and a mirror that are not placed along the observer's line of sight, for instance a Venus admiring herself in a small mirror, and when the actor's reflection in the mirror is visible to the observer. In this situation, observers tend to report, incorrectly, that Venus is also seeing herself in the mirror in the same location as the observer. We discuss this using famous paintings as examples.  相似文献

Two experiments investigated effects of articulatory processing on number data entry. Participants entered four-digit numbers presented as either words or numerals on a keyboard, either under an articulatory condition or in silence. In Experiment 1, the articulatory condition was articulatory suppression; in Experiment 2, it was vocalisation. In Experiment 1, the articulatory suppression group typed initial digits faster than the silent group, but for subsequent digits, the opposite pattern occurred at least with word stimuli. In Experiment 2, the silent group typed initial digits faster but typed subsequent digits somewhat slower than the vocalisation group. Thus, articulation of numbers, which promotes entry into the phonological loop of working memory, retards processing of initial digits but enhances processing of subsequent digits.  相似文献

Guillain-Barré syndrome (GBS) is a debilitating immunopathy that afflicts approximately 5,000 patients annually in the United States, a number that represents roughly half of the incidence of spinal cord injuries (J. M., Meythaler, 1997). Of these 5,000 new cases per year, 4–15% will die, 20% will possess deficits in ambulation or require ventilator assistance more than one year later, and more than two-thirds will have persistent fatigue (J. M., Meythaler, 1997; Hughes et al., 2003). These figures suggest that GBS is currently a legitimate cause of long-term disability.Many secondary complications may follow GBS that include dysautonomia, deep vein thrombosis, anemia, immobilization, and pain and sensory involvement (J. M., Meythaler, 1997; J. M. Meythaler, M. J. De Vivo, and W. C. Braswell, 1997). These medical complications have not been studied systematically, and the psychosocial complication of pain following GBS has certainly been overlooked in the literature. The present paper utilized a limited sample of 18 patients (N = 18) with persistent motor deficits at least one year after onset of GBS. We examined their pain and perceived quality of life as part of an ongoing federally funded study which will ultimately attempt to determine if 4-aminopyridine (4-AP) significantly improves motor function in patients with residual weakness from GBS. Findings suggest that while most persons do not rate themselves as depressed one year after GBS onset, 22% of respondents did exceed the cutoff for clinical depression on the CES-D. Age and gender do not appear to be related to any component of pain in GBS; however, self-ratings of physical and mental health do appear to be significantly related to pain experience. The nature of this relationship was not determined, and merits further investigation in future studies.  相似文献

Two experiments demonstrated that positive affect fosters intrinsic motivation, as reflected by choice of activity in a free-choice situation and by rated amount of enjoyment of a novel and challenging task, but also promotes responsible work behavior in a situation where the work needs to be done. Where there was work that needed to be done, people in the positive-affect condition reduced their time on the enjoyable task, successfully completed the work task, but also spent time on the more enjoyable task. These results indicate that positive affect does foster intrinsic motivation, and enjoyment and performance of enjoyable tasks, but not at the cost of responsible work behavior on an uninteresting task that needs to be done. Implications for the relationship between positive affect and such aspects of self-regulation as forward-looking thinking and self-control are discussed.

This article evaluates theories of the origins of sex differences in human behavior. It reviews the cross-cultural evidence on the behavior of women and men in nonindustrial societies, especially the activities that contribute to the sex-typed division of labor and patriarchy. To explain the cross-cultural findings, the authors consider social constructionism, evolutionary psychology, and their own biosocial theory. Supporting the biosocial analysis, sex differences derive from the interaction between the physical specialization of the sexes, especially female reproductive capacity, and the economic and social structural aspects of societies. This biosocial approach treats the psychological attributes of women and men as emergent given the evolved characteristics of the sexes, their developmental experiences, and their situated activity in society.  相似文献

Language is more than a source of information for accessing higher-order conceptual knowledge. Indeed, language may determine how people perceive and interpret visual stimuli. Visual processing in linguistic contexts, for instance, mirrors language processing and happens incrementally, rather than through variously-oriented fixations over a particular scene. The consequences of this atypical visual processing are yet to be determined. Here, we investigated the integration of visual and linguistic input during a reasoning task. Participants listened to sentences containing conjunctions or disjunctions (Nancy examined an ant and/or a cloud) and looked at visual scenes containing two pictures that either matched or mismatched the nouns. Degree of match between nouns and pictures (referential anchoring) and between their expected and actual spatial positions (spatial anchoring) affected fixations as well as judgments. We conclude that language induces incremental processing of visual scenes, which in turn becomes susceptible to reasoning errors during the language-meaning verification process.  相似文献

Abstract

In a sample of 1528 college students, we examined (1) whether several risk factors prospectively predicted exposure to potentially traumatic events (PTEs) over a 2-month period and (2) whether dependent events (i.e., those more likely to depend upon one's behavior or characteristics) and independent events were predicted by different risk factors. Logistic regression analyses indicated that overall subsequent PTE exposure was higher for women, those with more previous PTEs, and those who engaged in more binge drinking. Female gender and previous PTE exposure also predicted exposure to independent events. Subsequent dependent PTE exposure was predicted by more previous PTEs and binge drinking, and was somewhat higher in ethnic minority students. Implications for prevention efforts are discussed.  相似文献
