The perception of event structure in continuous activity is important for everyday comprehension. Although the segmentation of experience into events is a normal concomitant of perceptual processing, previous research has shown age differences in the ability to perceive structure in naturalistic activity, such as a movie of someone washing a car. However, past research has also shown that older adults have a preserved ability to comprehend events in narrative text, which suggests that narrative may improve the event processing of older adults. This study tested whether there are age differences in event segmentation at the intersection of continuous activity and narrative: narrative film. Younger and older adults watched and segmented a narrative film, The Red Balloon, into coarse and fine events. Changes in situational features, such as changes in characters, goals, and objects predicted segmentation. Analyses revealed little age-difference in segmentation behavior. This suggests the possibility that narrative structure supports event understanding for older adults.  相似文献

We investigated the role of the visual similarity of masked primes to targets in a lexical decision experiment. In the primes, some letters in the target (e.g., A in ABANDON) had either visually similar letters (e.g., H), dissimilar letters (D), visually similar digits (4), or dissimilar digits (6) substituted for them. The similarities of the digits and letters to the base letter were equated and verified in a two-alternative forced choice (2AFC) perceptual identification task. Using targets presented in lowercase (e.g., abandon) and primes presented in uppercase, visually similar digit primes (e.g., 484NDON) produced more priming than did visually dissimilar digit primes (676NDON), but little difference was found between the visually similar and dissimilar letter primes (HRHNDON vs. DWDNDON). These results were explained in terms of task-driven competition between the target letter and the visually similar letter.  相似文献

The aim of this study was to validate the Trait Emotional Intelligence Questionnaire (TEIQue v. 1.5) in a Lebanese sample and compare its factorial structure to that of a UK sample. There were similar gender and age distributions in both samples as well as satisfactory structural reliabilities at the global, factor, and facet levels. Results from exploratory factor analysis showed a four-factor structure similar to that originally obtained by the author of the questionnaire. There were strong correlations between the factor scores derived from the two datasets (≥.90). Tucker congruence supported the similarity between the Lebanese and UK factors. Independent-samples t tests showed that Lebanese participants scored higher on the Sociability factor and the facets of self-esteem, social awareness and emotion perception, whereas UK participants scored higher on the facets of stress management, optimism and relationships. Gender differences are also reported, and recommendations for future research discussed.  相似文献

It is generally accepted by educators and social psychologists that non-cognitive factors influence learning. Students who have a fixed view of intelligence believe that abilities are permanent. They view set-backs and the need for effort as evidence of lack of ability. Students with a growth mindset believe that intelligence and abilities are malleable. Intelligence grows with challenge. The objective of this study was to consider if teaching growth mindset to a group of college students in remedial math classes would increase the likelihood of passing the course and remaining in school. Results found a near statistically significant correlation between growth mindset and passing the course but no evidence to support growth mindset and retention. An intervention to teach growth mindset led to statistically small positive results as measured by Pearson’s product-moment correlation and independent sample t tests. Results suggest that combining a variety of interventions with weak academic students is required.  相似文献

Few studies have investigated simple discrimination and discrimination reversal learning by children younger than 2 years. Extant research has shown that teaching discrimination reversals may be challenging with this population. We used social reinforcement and correction procedures to teach simple simultaneous discrimination and discrimination reversal tasks involving three pairs of animal pictures displayed in a paper notebook. Participants were eight typically developing toddlers aged 15-23 months. All learned at least one simple discrimination/discrimination reversal problem. Four children learned all problems and showed evidence of learning set formation. Perhaps surprisingly, discrimination reversals were sometimes learned more rapidly than original discriminations. The procedures suggest a potentially efficient methodology for investigating more complex aspects of relational learning in toddlers.

Infant bilingualism offers a unique opportunity to study the relative effects of language experience and maturation on brain development, with each child serving as his or her own control. Event-related potentials (ERPs) to words were examined in 19- to 22-month-old English-Spanish bilingual toddlers. The children's dominant vs. nondominant languages elicited different patterns of neural activity in the lateral asymmetry of an early positive component (P100), and the latencies and distributions of ERP differences to known vs. unknown words from 200-400 and 400-600 ms. ERP effects also differed for 'high' and 'low' vocabulary groups based on total conceptual vocabulary scores. The results indicate that the organization of language-relevant brain activity is linked to experience with language rather than brain maturation.  相似文献

Humans rely on two main systems of quantification; one is nonsymbolic and involves approximate number representations (known as the approximate number system or ANS), and the other is symbolic and allows for exact calculations of number. Despite the pervasiveness of the ANS across development, recent studies with adolescents and school-aged children point to individual differences in the precision of these representations that, importantly, have been shown to relate to symbolic math competence even after controlling for general aspects of intelligence. Such findings suggest that the ANS, which humans share with nonhuman animals, interfaces specifically with a uniquely human system of formal mathematics. Other findings, however, point to a less straightforward picture, leaving open questions about the nature and ontogenetic origins of the relation between these two systems. Testing children across the preschool period, we found that ANS precision correlated with early math achievement but, critically, that this relation was nonlinear. More specifically, the correlation between ANS precision and math competence was stronger for children with lower math scores than for children with higher math scores. Taken together, our findings suggest that early-developing connections between the ANS and mathematics may be fundamentally discontinuous. Possible mechanisms underlying such nonlinearity are discussed.  相似文献

Interpersonal dependency and locus of control orientation were studied in obese and nonobese samples. The Interpersonal Dependency Inventory (Hirschfeld, Klerman, Gough, Barrett, & Korchin, 1977) and the I-E Scale (Rotter, 1966) were administered to 106 obese adults in outpatient treatment for obesity. The I-E Scale was also administered to 97 nonobese control subjects. As predicted, the obese subjects were significantly more internally oriented than has been previously identified in obese populations. These findings challenge currently held assumptions about locus of control in obese groups. Although the obese and nonobese subjects maintained similar overall dependency scores, the obese subjects were more likely to show low levels of autonomy in comparison with the nonobese subjects. Interpersonal dependency and locus of control dimensions associated with obese conditions may serve as useful predictor variables influencing obesity treatment approaches and outcome.  相似文献
