Individual Differences in Emotional Reactivity and Academic Achievement: A Psychophysiological Study
Sara Scrimin Gianmarco Alto Ughetta Moscardino Massimiliano Pastore Lucia Mason 《Mind, Brain, and Education》2016,10(1):34-46
Factors related to grade point average (GPA) are of great importance for students' success. Yet, little is known about the impact of individual differences in emotional reactivity on students' academic performance. We aimed to examine the emotional reactivity–GPA link and to assess whether self‐esteem and psychological distress moderate this relationship. Eighty undergraduate students reported on their GPA, self‐esteem, and psychological distress. Students' pupil radius was monitored during affective picture viewing to assess sympathetic activation in response to emotional stimuli. Cluster analysis on pupil reactivity to pictures identified low, average, and high emotionally reactive students. Regression analyses indicated that profiles of emotional reactivity were associated with GPA. This relationship was moderated by self‐esteem, but not psychological distress. Among students with higher emotional reactivity, those with lower self‐esteem reported poorer GPA. Findings document the importance of differences in students' emotional reactivity and self‐esteem in relation to academic success. 相似文献

The objectives of the current study were to identify the long‐term effects of Methylphenidate (Ritalin) on cognitive ability and academic achievement. A retrospective/longitudinal design was utilised in the study with dependent measures being scores from the Iowa Tests of Basic Skills (ITBS). The study included 17 experimental subjects who were identified with ADHD and placed on Methylphenidate between first and second grade. For each experimental child, a control child without ADHD was matched based on gender, Verbal IQ score, and family structure. Results of the study revealed that the Methylphenidate group's achievement was lower both before and after medication even after being matched on verbal abilities. The results also indicated that after receiving medication the Methylphenidate group's rate of learning was similar to the Control groups on Reading, Word Analysis, Listening, Vocabulary, and overall achievement. Finally, a positive relationship between dosage level and Listening subtest scores was observed while a negative relationship was obtained between dosage level and Vocabulary subtest scores. 相似文献

The existing literature on developmental dyslexia (hereafter: dyslexia) often focuses on isolating cognitive skills which differ across dyslexic and control participants. Among potential correlates, previous research has studied group differences between dyslexic and control participants in performance on statistical learning tasks. A statistical learning deficit has been proposed to be a potential cause and/or a marker effect for early detection of dyslexia. It is therefore of practical importance to evaluate the evidence for a group difference. From a theoretical perspective, such a group difference would provide information about the causal chain from statistical learning to reading acquisition. We provide a systematic review of the literature on such a group difference. We conclude that there is insufficient high-quality data to draw conclusions about the presence or absence of an effect. 相似文献

This study examined whether executive functions (EFs) moderate the association between independent and interdependent self-construals and social adjustment in 488 Moroccan, Romanian, and Italian preadolescents (ages 11–13) in Italy. Participants were assessed using self-report questionnaires and standardized EF tasks. Better working memory was related to increased social competence across all groups. High levels of inhibitory control were found to enhance the positive relation between interdependence and prosocial behavior for native Italian youth, and between interdependence and social competence for Moroccan preadolescents. High levels of cognitive flexibility boosted the interdependence–social competence link for the immigrant groups, whereas among native Italian preadolescents, the interdependence–social competence link was significant at low levels of flexibility. Implications for developmental theory and practice are discussed. 相似文献

We present IntoNews, a system to match online news articles with spoken news from a television newscasts represented by closed captions. We formalize the news matching problem as two independent tasks: closed captions segmentation and news retrieval. The system segments closed captions by using a windowing scheme: sliding or tumbling window. Next, it uses each segment to build a query by extracting representative terms. The query is used to retrieve previously indexed news articles from a search engine. To detect when a new article should be surfaced, the system compares the set of retrieved articles with the previously retrieved one. The intuition is that if the difference between these sets is large enough, it is likely that the topic of the newscast currently on air has changed and a new article should be displayed to the user. In order to evaluate IntoNews, we build a test collection using data coming from a second screen application and a major online news aggregator. The dataset is manually segmented and annotated by expert assessors, and used as our ground truth. It is freely available for download through the Webscope program.1 Our evaluation is based on a set of novel time-relevance metrics that take into account three different aspects of the problem at hand: precision, timeliness and coverage. We compare our algorithms against the best method previously proposed in literature for this problem. Experiments show the trade-offs involved among precision, timeliness and coverage of the airing news. Our best method is four times more accurate than the baseline. 相似文献

There are widespread aspirations to focus undergraduate biology education on teaching students to think conceptually like biologists; however, there is a dearth of assessment tools designed to measure progress from novice to expert biological conceptual thinking. We present the development of a novel assessment tool, the Biology Card Sorting Task, designed to probe how individuals organize their conceptual knowledge of biology. While modeled on tasks from cognitive psychology, this task is unique in its design to test two hypothesized conceptual frameworks for the organization of biological knowledge: 1) a surface feature organization focused on organism type and 2) a deep feature organization focused on fundamental biological concepts. In this initial investigation of the Biology Card Sorting Task, each of six analytical measures showed statistically significant differences when used to compare the card sorting results of putative biological experts (biology faculty) and novices (non–biology major undergraduates). Consistently, biology faculty appeared to sort based on hypothesized deep features, while non–biology majors appeared to sort based on either surface features or nonhypothesized organizational frameworks. Results suggest that this novel task is robust in distinguishing populations of biology experts and biology novices and may be an adaptable tool for tracking emerging biology conceptual expertise. 相似文献

Hyperlink format, categorization abilities and memory span as contributors to deaf users hypertext access 总被引：1，自引：0，他引：1

Sixty deaf and hearing students were asked to search for goods in a Hypertext Supermarket with either graphical or textual links of high typicality, frequency, and familiarity. Additionally, they performed a picture and word categorization task and two working memory span tasks (spatial and verbal). Results showed that deaf students were faster in graphical than in verbal hypertext when the number of visited pages per search trial was blocked. Regardless of stimuli format, accuracy differences between groups did not appear, although deaf students were slower than hearing students in both Web search and categorization tasks (graphical or verbal). No relation between the two tasks was found. Correlation analyses showed that deaf students with higher spatial span were faster in graphical Web search, but no correlations emerged between verbal span and verbal Web search. A hypothesis of different strategies used by the two groups for searching information in hypertext is formulated. It is suggested that deaf users use a visual-matching strategy more than a semantic approach to make navigation decisions. 相似文献

The purpose of this study was to investigate the effects of using an internal versus external focus of attention during resistance training on muscular adaptations. Thirty untrained college-aged men were randomly assigned to an internal focus group (INTERNAL) that focused on contracting the target muscle during training (n?=?15) or an external focus group (EXTERNAL) that focused on the outcome of the lift (n?=?15). Training for both routines consisted of 3 weekly sessions performed on non-consecutive days for 8 weeks. Subjects performed 4 sets of 8–12 repetitions per exercise. Changes in strength were assessed by six repetition maximum in the biceps curl and isometric maximal voluntary contraction in knee extension and elbow flexion. Changes in muscle thickness for the elbow flexors and quadriceps were assessed by ultrasound. Results show significantly greater increases in elbow flexor thickness in INTERNAL versus EXTERNAL (12.4% vs. 6.9%, respectively); similar changes were noted in quadriceps thickness. Isometric elbow flexion strength was greater for INTERNAL while isometric knee extension strength was greater for EXTERNAL, although neither reached statistical significance. The findings lend support to the use of a mind–muscle connection to enhance muscle hypertrophy. 相似文献
