Previous research into the relationship between attributions and academic performance has produced contradictory findings that have not been resolved. The present research examines the role of specific dimensions of attributional style in predicting subsequent academic performance in a sample of pupils (N = 979) from both high‐ and low‐achieving schools. Hierarchical regression and moderation analyses indicate that internal, stable, and global, attributional styles for positive events predict higher levels of academic performance. Global attributions for negative events were related to poorer performance across all schools. Stable attributions for negative events were related to higher levels of performance in high‐achieving schools but not in low‐achieving schools. Higher levels of internality for negative events were associated with higher performance only in low achieving schools. 相似文献

When forecasting how they will feel in the future, people overestimate the impact that imagined negative events will have on their affective states, partly because they underestimate their own psychological resiliency. Because self-affirmation enhances resiliency, two studies examined whether self-affirmation prior to forecasting reduces the extremity of affective forecasts. Participants in self-affirmation conditions completed a values scale or wrote an essay asserting their most important value, whereas participants in the no-affirmation condition asserted a relatively unimportant value. Participants then predicted their affective reactions to a negative or positive imagined event. In both studies, self-affirmation reduced the unpleasant affect expected to result from a negative event, but had no impact on affective forecasts for a positive event. This pattern was mediated by participants’ cognitive appraisals of the imagined event, but not by differential focus on that event. Results are consistent with self-affirmation activating or enhancing psychological resiliency to counteract immune neglect during affective forecasting of a negative event. 相似文献

Agrammatic aphasia is characterized by severely reduced grammatical structure in spoken and written language, often accompanied by apparent insensitivity to grammatical structure in comprehension. Does agrammatism represent loss of linguistic competence or rather performance factors such as memory or resource limitations? A considerable body of evidence supports the latter hypothesis in the domain of comprehension. Here we present the first strong evidence for the performance hypothesis in the domain of production: an augmentative communication system that markedly increases the grammatical structure of agrammatic speech while providing no linguistic information, functioning merely to reduce on-line processing demands.

Shaping and fading techniques were employed to replace written instructions used in computerized behavioral tests. Apple Macintosh computers and HyperCard with Pascal extensions were chosen as the development environment to implement the new techniques. Initial Findings demonstrate the effectiveness and relative efficiency of shaping techniques to teach correct performance on the Symbol-Digit Test. 相似文献

We investigated the influence of negative emotional pictures on associative memory. A visual object was embedded in the periphery of negative emotional or neutral pictures. Memory was assessed for central item (pictorial) information, peripheral (object) information, and the association between item and peripheral information. On tests of item information, negative emotional pictures were remembered better than neutral pictures. However, associative memory between item and peripheral information was less accurate when the pictures were negative compared to neutral. This occurred despite equivalent recall (Experiments 1 and 2) and recognition (Experiment 2) for the peripheral objects themselves. Further experiments confirmed that performance on the associative test was not influenced by testing order (Experiment 3). These findings suggest that negative emotional arousal can particularly disrupt the associative binding of peripheral information to a central emotional event. 相似文献

Investigators have evaluated two procedural variations for conducting a functional analysis of inappropriate mealtime behavior exhibited by children with feeding problems. One method involves prompting bites only in the escape condition (e.g., Najdowski et al., 2008). Another method involves prompting bites across all conditions (e.g., Piazza et al., 2003). We assessed the food refusal of 3 children diagnosed with a feeding disorder by comparing the two variations. The two methods resulted in different outcomes for 2 of 3 children. Prompting bites only in the escape condition identified a single function (i.e., escape). Prompting bites across all conditions identified multiple functions (i.e., escape and attention). We then examined the relative effects of extinction procedures (individually and in combination) to determine the validity of each method. Results of the treatment evaluation suggested that the procedural variation that failed to identify an attention function for 2 of 3 children produced false negative findings. 相似文献

We conducted functional analyses of the inappropriate mealtime behavior of 5 children diagnosed with feeding problems. Then, we compared the effects of differential and noncontingent reinforcement, and the relative effects of escape extinction with and without differential or noncontingent reinforcement, when escape extinction appeared necessary. Both reinforcement procedures were effective without escape extinction to treat food refusal for 1 child, but only differential reinforcement was effective without escape extinction to treat the child's liquid refusal. Escape extinction was necessary for 4 of 5 children. The addition of positive reinforcement resulted in beneficial effects (i.e., more stable acceptance, decreased inappropriate mealtime behavior or negative vocalizations) with 3 of 4 children. With escape extinction, differential reinforcement was more effective to treat food refusal for 2 children and noncontingent reinforcement was more effective for 1 child. 相似文献

Monolingual and bilingual children's social preferences for monolingual and bilingual speakers 下载免费PDF全文

Past research has shown that young monolingual children exhibit language‐based social biases: they prefer native language to foreign language speakers. The current research investigated how children's language preferences are influenced by their own bilingualism and by a speaker's bilingualism. Monolingual and bilingual 4‐ to 6‐year‐olds heard pairs of adults (a monolingual and a bilingual, or two monolinguals) and chose the person with whom they wanted to be friends. Whether they were from a largely monolingual or a largely bilingual community, monolingual children preferred monolingual to bilingual speakers, and native language to foreign language speakers. In contrast, bilingual children showed similar affiliation with monolingual and bilingual speakers, as well as for monolingual speakers using their dominant versus non‐dominant language. Exploratory analyses showed that individual bilinguals displayed idiosyncratic patterns of preference. These results reveal that language‐based preferences emerge from a complex interaction of factors, including preference for in‐group members, avoidance of out‐group members, and characteristics of the child as they relate to the status of the languages within the community. Moreover, these results have implications for bilingual children's social acceptance by their peers. 相似文献

Numerical abilities have been demonstrated in a variety of non-human vertebrates. However, underlying biological mechanisms have been difficult to study due to a paucity of experimental tools. Powerful genetic and neurobiological tools already exist for the zebrafish, but numerical abilities remain scarcely explored with this species. Here, we investigate the choice made by single experimental zebrafish between numerically different shoals of conspecifics presented concurrently on opposite sides of the experimental tank. We examined this choice using the AB strain and pet store zebrafish. We found zebrafish of both populations to generally prefer the numerically larger shoal to the smaller one. This preference was significant for contrasted ratios above or equalling 2:1 (i.e. 4 vs. 0, 4 vs. 1, 8 vs. 2, 6 vs. 2 and 6 vs. 3). Interestingly, zebrafish showed no significant preference when each of the two contrasted shoals had at least 4 members, e.g. in a contrast 8 versus 4. These results confirm that zebrafish possess the ability to distinguish larger numbers of items from smaller number of items, in a shoaling context, with a potential limit above 4. Our findings confirm the utility of the zebrafish for the exploration of both the behavioural and the biological mechanisms underlying numerical abilities in vertebrates. 相似文献
