The limited capacity theory is often cited to account for negative correlations between choice reaction time and different IQ measures. It is claimed, since working memory has strictly limited capacity to process a great amount of vital information and STM information decays if not rehearsed, that speed is an indispensable condition of efficient dealing with cognitive tasks. It ensures good performance before important information is forgotten. In the present experiment a special kind of task was applied‐one which supposedly puts a substantial load on the system of working memory. It was hypothesized that subjects dealing well with this task would also obtain high scores on general ability tests. The data obtained from 48 psychology students in the self‐paced, computer assisted study did not confirm this hypothesis. The data are interpreted as posing a challenge for the limited capacity theory, which must either be reformulated or replaced by better elaborated theoretical constructions.

Self‐efficacy is defined as a person's beliefs in his or her own abilities to successfully complete a task and has been shown to influence student motivation and academic behaviors. More specifically, anatomical self‐efficacy is defined as an individual's judgment of his or her ability to successfully complete tasks related to the anatomy curriculum; these include dissecting, learning anatomical concepts, and applying anatomical knowledge to clinical situations. The purpose of this study was to investigate the influence of anatomical self‐efficacy on the academic performance of students enrolled in a medical gross anatomy course. To obtain students' anatomical self‐efficacy ratings, surveys containing the same anatomical self‐efficacy instrument were completed by first‐year medical students at a southeastern United States allopathic medical school after each of four gross anatomy assessments. Additional data collected included student demographic information, Medical College Admission Test® (MCAT®) scores, and anatomy assessment scores, both written examination and laboratory practical. To investigate the potential predictive nature of self‐efficacy for academic performance on both the written examination and the laboratory practical components of medical anatomy assessments, hierarchical linear regression analyses were conducted. For these analyses, academic ability (defined as the sum of the physical sciences and biological sciences MCAT scores) was controlled. The results of the hierarchical linear regressions indicated that all four laboratory practical scores were predicted by the corresponding self‐efficacy ratings, while two (i.e., thorax/abdomen and pelvis/lower limb) of the four written examination scores were predicted by the corresponding self‐efficacy ratings (P ≤ 0.05).

Longitudinal associations of domain‐general and numerical competencies with individual differences in children's understanding of fractions were investigated. Children (n = 163) were assessed at 6 years of age on domain‐general (nonverbal reasoning, language, attentive behavior, executive control, visual‐spatial memory) and numerical (number knowledge) competencies; at 7 years on whole‐number arithmetic computations and number line estimation; and at 10 years on fraction concepts. Mediation analyses controlling for general mathematics ability and general academic ability revealed that numerical and mathematical competencies were direct predictors of fraction concepts, whereas domain‐general competencies supported the acquisition of fraction concepts via whole‐number arithmetic computations or number line estimation. Results indicate multiple pathways to fraction competence.  相似文献

Disorientation and confusion have been identified as significant problems for older persons newly admitted to nursing homes and other institutions. The purpose of this study was to determine which of two orientating systems might be best for helping older people become accustomed to a strange environment. Middle‐aged and elderly residents of a nursing home were dichotomized by performance on three memory tests and then were given two paired‐associate learning tasks. In one task colors and a place in the nursing home were to be associated; in the other symbols and a place in the nursing home were to be associated. The results indicated that the symbol‐place paired‐associate task was learned more rapidly than the color‐place task by both high and low memory ability groups, and that the lower memory ability group showed slower learning of the color‐place task compared to the higher memory ability group. In addition, learning was slower on both tasks when the color‐place task was the first presented. These results indicated that symbol‐place codes may be more useful than color‐place codes as orientation markers and suggested that evaluation of learning performance should include examination of order effects.  相似文献

Memory performance predictions are subjective estimates of possible memory task performance. The purpose of this study was to examine possible factors related to changes in word list performance predictions made by younger and older adults. Factors included memory self-efficacy, actual performance, and perceptions of performance. The current study examined the age differences in a sample of 59 older adults (M = 76.83 years) and 52 younger adults (M = 21.19 years) on memory predictions and the accuracy of those predictions for both an immediate and delayed word recall task. While memory self-efficacy did not influence predictions for either group, perceived and actual performance at immediate recall was related to accuracy of predictions at delay for both groups. In addition, there was a significant age-by-time interaction such that older adults became more accurate over time whereas younger adults declined slightly in their prediction accuracy. These findings suggest that older adults are able to make accurate adjustments to their predictions based on both their perceived and actual performance on tasks.  相似文献

Abstract

The aim of this study was to examine the relationships between verbal short‐term memory, phonemic awareness, and reading ability, in children with a specific reading difficulty. The results confirmed the frequently reported finding that most, if not all children with a specific reading difficulty have poor phonological awareness. In addition, poor phonological awareness in the reading‐difficulty group was associated with significantly poorer nonword reading ability, and with poorer phonological memory. When the reading‐difficulty group was further subdivided with respect to Digit Span performance there was no difference in nonword reading with respect to this overall verbal short‐term memory measure. However, poor short‐term memory, regardless of phonological awareness level, was significantly associated with a lower WISC III Verbal IQ, in particular, significantly poorer performance on the WISC III Vocabulary, Comprehension and Similarities subtests, as well as with significantly poorer reading comprehension. In addition, poor short‐term memory regardless of phonological awareness ability was associated with poorer spelling and arithmetic performance.  相似文献

Three UK studies on the relationship between a purpose‐built instrument to assess the importance and development of 15 ‘soft skills’ are reported. Study 1 (N = 444) identified strong latent components underlying these soft skills, such that differences between‐skills were over‐shadowed by differences between‐students. Importance and improving ratings on these skills predicted academic performance and accounted for the effects of personality on academic performance. Study 2 replicated the structure of the soft skills inventory and associations with academic performance in a larger sample (N = 1309). Examination of mean differences across faculties (humanities, life sciences, hard sciences) revealed higher soft skills ratings in ‘softer’ courses. Study 3 (N = 87) incorporated an IQ measure, which was found to be negatively related to importance ratings on soft skills. Results highlight the cohesive structure of beliefs concerning various non‐academic skills and their significant links to educationally relevant individual differences. Theoretical, methodological and applied implications are considered.  相似文献

Second- and fourth-grade children were classified according to their knowledge of soccer (experts vs. novices) and IQ (high vs. low), and given 2 sort-recall tasks. One task included items related to the game of soccer and the other included items from familiar natural language categories. Previous research has shown that expertise in a subject can compensate for low levels of performance on text comprehension tasks. Our results, the first examining the effects of both expertise and intelligence on a strategic memory task, were that soccer expert children recalled more items on the soccer list but not on the nonsoccer list than soccer novice children. However, soccer expertise did not modify a significant effect of IQ level, with high-IQ children recalling more than low-IQ children for all contrasts. Interest in soccer was found to be related to expertise but did not contribute to differences in memory performance. The results demonstrate that the knowledge base plays an important role in children's memory, but that domain knowledge cannot fully eliminate the effects of IQ on sort-recall tasks using domain-related materials. That is, although rich domain knowledge seemed to compensate for low aptitude, in that low-aptitude experts performed at the level of high-aptitude novices, its effects were not strong enough to eliminate performance differences between high- and low-aptitude soccer experts.  相似文献

This paper reports the results of a two‐year longitudinal study of the relationship between self‐assessed intelligence (SAI) and academic performance (AP) in a sample of 184 British undergraduate students. Results showed significant correlations between SAI (both before and after taking an IQ test) and academic exam marks obtained two years later, even when IQ scores were partialled out. Several continuous assessment indicators (notably attendance, oral expression, and motivation) were also significantly correlated with SAI, even when IQ scores were controlled. A series of hierarchical regressions indicated that although exam grades were best predicted by IQ, SAI showed significant incremental validity in the prediction of AP, accounting for an additional 3% of exam, 9% of continuous assessment, and 2% of essay grades. Results are discussed with regard to current trends to integrate individual differences underlying AP.  相似文献

This study compared the relationships of self‐efficacy and reasoning ability to achievement in introductory college biology. Based on the hypothesis that developing formal and postformal reasoning ability is a primary factor influencing self‐efficacy, a significant positive correlation was predicted between reasoning ability and degree of self‐efficacy to complete biological tasks. Further, reasoning ability was predicted to be more highly correlated with course achievement than self‐efficacy. The study involved pre‐ and posttesting 459 introductory biology students. Both self‐efficacy and reasoning ability increased during the semester. As predicted, self‐efficacy and reasoning ability were positively correlated. Depending on the nature of the achievement measure, reasoning ability accounted for some 15 to 30 times more variance in achievement than self‐efficacy. Also, as predicted, reasoning ability was a strong predictor of self‐efficacy, but self‐efficacy was not a strong predictor of reasoning ability. Self‐efficacy estimates and achievement were higher for the concrete tasks than for the formal tasks and higher for the formal tasks than for the postformal tasks. In general, students tended to overestimate their abilities to carry out the concrete, formal, and postformal tasks. Results support the study's working hypothesis that intellectual development continues for some students during the college years, that a postformal level of intellectual development exists, and that reasoning ability is a primary factor influencing both self‐efficacy and achievement. Student overestimation of their abilities may contribute to complacency, lack of effort, and to less than optimal achievement. Consequently, it may be advantageous early in the semester to provide students with particularly challenging tasks that “shock” them out of their complacency and perhaps increase their effort, their reasoning skills, and their achievement. © 2006 Wiley Periodicals, Inc.

The self‐reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self‐ or other‐image paired with a concrete object. In Study 1, 4‐ to 6‐year‐old children (N = 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self‐paired objects. Study 2 (N = 55) replicated this finding in source memory. In Study 3 (N = 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self‐paired items. These findings are discussed with reference to mechanisms that ensure information of potential self‐relevance is reliably encoded.  相似文献

A study was designed to test 2 alternative hypotheses—a symbolic hypothesis and an executive function hypothesis—for the imitation and pantomime deficits found in previous studies of autism. The subjects were 17 adolescent high-functioning subjects with autism spectrum disorders and 15 clinical comparison subjects who were matched on chronological age and verbal IQ. Meaning and sequence were manipulated in facial and manual imitation tasks. Sequence was manipulated in the pantomime and control tasks. Recognition memory and motor control tasks were matched to the experimental tasks. The results provided no support for the symbolic deficit hypothesis; meaning aided rather than hindered the performance of the group with autism. Partial support for the executive deficit hypothesis was found. There were no group differences on motor control tasks, and few on the memory control tasks, arguing against deficits in motor initiation, basic motor coordination, or visual recognition memory.  相似文献

In the development of performance excellence, the relative roles played by intellectual ability and motivation remain speculative. This study investigates the role played by general intelligence, school environment, self‐efficacy, and aspects of personal identity in the formation of learning motivation in German students attending the Gymnasium schools. Using self‐reports of academic achievement and scores on a shortened version of the Berlin intelligence structure test for adolescence to differentiate students as achievers or underachievers, ninth‐grade students were administered a battery of self‐report instruments, designed to measure learning motivation, school environment, self‐efficacy, and personal identity. After the posited factor structure was confirmed, factor scores were computed and then used as data in hierarchical regression analyses using learning motivation as the criterion variable. The results showed that the greatest predictors of learning motivation were variables related to personal identity‐style, rather than general intelligence, supporting the hypothesis that learning motivation is a moderator variable of intellectual achievement for students with intellectual giftedness, rather than an inherent component of giftedness.  相似文献

Relational reasoning, the ability to detect meaningful patterns, matures through adolescence. The unique contributions of verbal analogical and nonverbal matrix relational reasoning to science and maths are not well understood. Functional magnetic resonance imaging data were collected during science and maths problem‐solving, and participants (N = 36, 11–15 years) also completed relational reasoning and executive function tasks. Higher verbal analogical reasoning associated with higher accuracy and faster reaction times in science and maths, and higher activation in the left anterior temporal cortex during maths problem‐solving. Higher nonverbal matrix reasoning associated with higher science accuracy, higher science activation in regions across the brain, and lower maths activation in the right middle temporal gyrus. Science associations mostly remained significant when individual differences in executive functions and verbal IQ were taken into account, while maths associations typically did not. The findings indicate the potential importance of supporting relational reasoning in adolescent science and maths learning.  相似文献

The paper focuses on the question of how to advance collaboration through the Web and support lifelong learning. First, the theoretical framework and architecture of a new web‐based tool, the ‘IQ Team’, is introduced. IQ Team is an interactive online assessment and support system to learn social skills needed in cooperative work, and belongs in an interactive online assessing and tutoring system, ‘IQ Form’, developed for the Finnish Virtual University. IQ Team has three main elements: (1) interactive self‐evaluation test banks, (2) online tutoring sets and (3) learning diaries. In the creation of IQ Team, the validation process was conducted with two samples (n = 259 and n = 275). The online students’ social skills in different groups were explored, and the feedback data from different user groups were analysed. The online students scored high values for social skills, and no differences were discerned between university, Open University and technical students. The qualitative data (n = 35) were collected in order to get users’ feedback of the tool. The qualitative data consisted of interviews, open‐ended questions and online discussions. The users of IQ Team reflected that the tool benefited them to become aware of their group work skills and developed their collaborative learning skills. IQ Team provides a powerful tool for online instruction and communication in higher education and in the Open University to promote joint‐regulated learning.  相似文献

Changes in medical school curricula often require educators to develop teaching strategies that decrease contact hours while maintaining effective pedagogical methods. When faced with this challenge, faculty at the University of Cincinnati College of Medicine converted the majority of in‐person histology laboratory sessions to self‐study modules that utilize multiple audiovisual modalities and a virtual microscope platform. Outcomes related to this shift were investigated through performance on in‐house examinations, results of the United States Medical Licensing Examination® (USMLE®) Step 1 Examination, and student feedback. Medical School College Admissions Test® (MCAT®) scores were used as a covariate when comparing in‐house examinations. Results revealed no significant change in performance on in‐house examinations when the content being assessed was controlled (F(2, 506) = 0.676, P = 0.51). A significant improvement in overall practical examination grade averages was associated with the self‐study modules (F(6, 1164) = 10.213, P < 0.01), but gradual changes in examination content may explain this finding. The histology and cell biology portion of USMLE Step 1 Examination remained consistent throughout the time period that was investigated. Student feedback regarding the self‐study modules was positive and suggested that features such as instructor narrated videos were an important component of the self‐study modules because they helped recreate the experience of in‐person laboratory sessions. Positive outcomes from the student perspective and no drop in examination performance suggests that utilizing self‐study modules for histology laboratory content may be an option for educators faced with the challenge of reducing contact hours without eliminating content.

Two experiments explored the relationship between 15‐16‐year‐old ninth‐formers’ working memory (WM) capacity and school achievement. In the first experiment, WM capacity was measured administering complex WM span tests on 107 subjects. These measures correlated highly significantly with performance in four school subjects: mathematics, foreign language, Finnish (native language) and geography. In the second experiment, additional WM tasks were used to measure two WM components: the phonological loop and the central executive component as suggested by Baddeley (1986). The tasks that were assumed to measure the central executive were strongly linked to performance in school subjects. Maximally, they shared 31 % of the variance with school achievement. Partial correlations showed that digit span correlated, independently of the central executive measures, with performance in foreign language. This result suggested that the phonological loop is specifically related to foreign language learning. The relationship between WM and the general intelligence factor g is discussed.  相似文献

The present study explores the relationship between sentence recall and reading and language skills in a group of 7–11-year-old children with learning difficulties. While recent studies have found that performance on sentence recall tasks plays a role in learning, it is possible that this contribution is a reflection of shared resources with working memory. In order to investigate whether sentence recall was uniquely associated with reading and language skills, differences associated with IQ and working memory capacity were statistically controlled. A sample of 72 children was tested on measures of verbal complex memory, verbal short-term memory, sentence recall, expressive vocabulary, verbal and performance IQ, reading and language skills. Both sentence recall and verbal complex memory shared unique links with reading skill, and sentence recall was uniquely associated with language skills. This finding indicates that resources in long-term memory also play an important diagnostic role in reading and language abilities. The implications for educational practice are discussed.  相似文献

Objective and subjective indices of imagery and verbal ability and their relationship to recognition memory for pictures and concrete words were examined in a large correlational study. Objective spatial tests of imagery proved to be better predictors of picture recognition than were self‐assessments, the Flags test excepted. Spatial tests also predicted word memory in males, but not females. Imagery control and imagery vividness bore little relation to recognition; vividness within specific modalities may have some influence, however, particularly in males. Verbal fluency and verbal comprehension were either unrelated or marginally negatively related to performance. In general, a more specialised pattern of ability‐performance correlations emerged for females than for males.  相似文献

Abstract The purpose of this article is to provide an overview of research‐based interventions that incorporate self‐regulation strategies to improve mathematics performance of students with learning disabilities (LD). Self‐regulation is a metacognitive function essential to academic success. Students with LD are notoriously poor at self‐regulation and must be taught explicitly to monitor and control their cognitive activities as they engage in academic tasks such as mathematical problem solving. This article describes intervention studies that use self‐regulation strategies to improve mathematics performance of students with LD at the elementary, middle, and secondary school levels. Several techniques to facilitate effective implementation of self‐regulation instruction in the classroom are presented.  相似文献
