Semistructured interviews were used to identify memory strategies used by 35 older adults. Five types of tasks were used: paired‐associate learning, free recall, serial recall, rule learning, and reading comprehension. For the first three tasks, two types of materials were developed: experimental and everyday. The nine memory activities were presented separately. Participants were asked to describe the strategies they would use for each activity. Order of presentation for the experimental and everyday materials was counterbalanced. Examination of the frequency data revealed differences in the number and type of strategies reported for the five types of learning tasks. An analysis of variance revealed that the group receiving the three everyday tasks first reported a significantly greater use of strategies on all tasks. These results indicate that the elderly may have limited repertoires of alternative memory strategies and that the types of materials used can significantly affect their performance.  相似文献

Abstract

The present study examined die influence self-concept played in a verbal free recall and non-verbal paired associate learning task with gifted children. Twenty-four male and 24 female pre-adolescents were divided into high and low self-concept groups for each sex, forming four groups with 12 subjects in each group. A 20-item free recall task and a five-trial, six-item non-verbal paired associate learning task were administered. High self-esteem boys and girls showed significantly greater mastery of all learning tasks than lower self-concept counterparts. Analysis of organization scores supported the use of more sophisticated learning strategies by children with higher self-perceptions.  相似文献

A group of young and elderly females were tested on a paired‐associate task. The responses of the paired‐associates were consonant‐vowel‐consonant trigrams (CVCs) that were either high in association value (AV) on Glaze norms and low on Archer norms, or low in AV on Glaze norms and high on Archer. The results indicated that older individuals made more intrusion errors on the CVCs high in AV on the Glaze norms but low on the Archer norms. Results showed that associations were being formed across the life‐span of the individual.  相似文献

It has been suggested that the ability to learn a foreign language is related to working memory. However, there is no clear evidence about which component of working memory may be involved.Two experiments investigated working memory problems in groups of seventh and eighth grade Italian children with difficulties in learning English as a second language. They were compared with control groups of children matched for age, education, school, and intelligence who differed for foreign language learning ability.Experiment 1 focused on clarifying how modality-specific the memory problem of children with a foreign language learning difficulty (FLLD) is. Verbal working memory tasks (forward and backward digit span) were proposed together with visuospatial working memory (VSWM) tasks. Groups showed a significant difference only in the more passive verbal working memory task, that is, the forward digit span.Experiment 2 focused on clarifying how central the verbal working memory problem of students with an FLLD is. A nonword repetition task and an Italian version of the listening span test were proposed. Groups differed significantly in both tasks. However, differences in the listening span test disappeared when nonword repetition performance was partialed out. It was concluded that a difficulty in learning a foreign language is mainly related to the more passive aspects of verbal working memory, typically associated with the articulatory loop.  相似文献

The subjects, 24 old (mean age, 69 yr) and 24 young (mean age, 19 yr) people, were given one learning trial on paired associate lists under each of four temporal conditions: (1) 3 sec study (association) interval; (2) self‐paced study interval; (3) self‐paced study interval and 4 sec registration interval; (4) self‐paced study and registration intervals. The response interval for the single recall trial was self‐paced for all conditions. The subject was instructed to use the registration interval to ensure that the association between the paired items was “fixed” in his or her mind. The recall scores of the elderly subjects but not the young subjects improved significantly as a function of the registration interval. The results suggest that with advanced age more time is required for information processing, and specifically for the registration of an association and/or its transfer from primary to secondary memory. The significant improvement of the older subjects from the paced‐study‐interval condition to the self‐paced‐study‐and‐registration‐intervals condition supports the contention that modification of conditions under which the older person is expected to perform can result in substantial performance increments.  相似文献

To investigate students' self‐monitoring practice and effects of educational level and task importance on self‐monitoring, 510 students, varying in educational level from elementary through graduate school, reported the self‐monitoring strategies they employed in three learning situations with different levels of task importance. The study identified six self‐monitoring strategies used by students but found a low involvement in self‐monitoring at all educational levels. It was found that older students used more complex self‐monitoring strategies more frequently than younger students. The study also showed that students' self‐monitoring increased with task importance. The self‐monitoring deficiencies that students experienced in difficult learning tasks were attributed to the lack of a system of self‐monitoring. Educational applications of teaching self‐monitoring strategies and developing self‐monitoring systems for difficult learning tasks were discussed.  相似文献

This paper reports two related studies intended to explore the interactions between children’s metacognitive abilities, their working memory capacity, the development and selection of strategies and their performance on problem-solving tasks. In the first study, a sample of 20 children aged 5 and 6 were presented with a reclassification task. In the second study, a sample of 72 children aged 6, 8 and 10 were presented with a multidimensional discrimination learning (MDL) task. Data was collected related to the children’s metacognitive abilities, working memory capacity, response strategies and task performance. The results indicated that performance on both tasks was dependent upon developmentally changing interactions between these various aspects of cognitive functioning. In particular, the relationship of working memory capacity to performance was dependent upon metacognitive abilities. The results also suggested that metacognitive awareness did not directly affect performance, but that such a relationship was dependent upon the development of strategic control. The implications of these results for understanding U-shaped behavioural growth and other common developmental patterns are discussed. Within the educational sphere, the study emphasises the significance and possibility for children as learners of fostering certain kinds of metacognitive ability.  相似文献

Many models have hypothesized that multimedia comprehension requires the concurrent processing of verbal and visuospatial information by limited information processing systems. However, in spite of the emphasis devoted to the concurrent processing of verbal and visuospatial information, little research has so far investigated the specific role played by verbal and visuospatial abilities in multimedia comprehension. The present paper aims to study the specific involvement of verbal and visuospatial working memory in multimedia learning. Ninety‐two students (39 boys and 53 girls) from a middle school in a small city in the northeast of Italy, were asked to learn new information on the physical and social geography of Germany from a hypermedium. Participants were also required to perform a reading comprehension test, two short‐term memory tasks, and two working memory tasks, which assessed either verbal or visuospatial memory. The results support the hypothesis that both verbal and visuospatial working memory sub‐components play a role in hypermedium processing, but with specific and distinct functions: the performance in the verbal working memory task was able to predict the semantic knowledge children can derive from hypermedia learning. In contrast, visuospatial working memory seemed to have lower connections to the semantic knowledge children derived from a hypermedia document, whereas its role emerged in the ability to construct a representation of the document structure.  相似文献

Fluid/spatial intelligence, crystallized intelligence and their relationships to verbal and visuospatial working memory (WM) were studied. A total of 120 Finnish Air Force recruits participated in this study. Fluid/spatial intelligence was assessed using four different tasks, while crystallized intelligence was defined with the help of test scores of Finnish upper secondary school National Matriculation Tests in three different academic subjects and one additional Verbal Relations task. Complex WM span tasks were used to measure visuospatial and verbal WM capacities. Structural equation modeling indicated that verbal WM was related to crystallized intelligence when both WM tasks were included in the model, whereas performance on the visuospatial WM task was related to fluid/spatial intelligence, but not to crystallized intelligence. Verbal WM was not related to fluid intelligence when used as a single WM predictor. The results indicate that verbal WM might be related to verbal ability and learning at school, while visuospatial WM is relatively strongly related to nonverbal reasoning and spatial visualization. The current results further suggest that WM capacity is not a unitary system.  相似文献

Lunzer reported data suggestive of a stage of cognitive development manifest between 9 and 11 years of age characterized by the ability to avoid drawing premature inferences when faced with ambiguity (i.e., accept lack of closure [ALC]). The present study sought to test this hypothesis. Inference tasks emphasizing ALC, memory, and hypothetico-deductive reasoning were administered to 67 males and 74 females (5-12 years in age). Although use of ALC increased with age, considerable use was evidenced on a simple task among 7-8-year-olds. On tasks hypothesized to place increasing demands on working memory, longer tasks were found to be more difficult. Marked improvement due to memory aids suggested that task difficulty results from limitations in working memory as predicted by Pascual-Leone's theory. Tasks requiring hypothetico-deductive reasoning were found to be most difficult. Performance was related to subject's spontaneous use of ALC. Lack of appropriate strategies was hypothesized to prevent solution rather than lack of logical competence. In conclusion, the relationship of ALC to age appears to be mediated by memory development rather than logical development.  相似文献

This study investigated the effect of individual differences in state anxiety on tasks tapping the central executive, phonological, and visuo‐spatial components of working memory (WM). It was designed to test Eysenck and Calvo’s processing efficiency theory (PET) which suggests that the phonological and executive components of WM may be important in understanding learning outcomes in anxiety. Typically‐developing children aged 9–10 years were split into high and low state anxiety groups. They performed three WM tasks – forward and backward digit span (assumed to measure phonological and central executive components of WM respectively) and a spatial working memory task (measuring the visuo‐spatial component of WM). Measurements of task accuracy were taken as an indicator of performance outcome or effectiveness. Time taken to complete tasks and a subjective rating of mental effort were taken as measurements of performance efficiency. No differences were found between high and low state anxiety groups in task accuracy for any measure. Children in the high state anxiety group, however, took longer to complete the backward digit span task and reported increased mental effort in the forward digit span task, indicating some effect of anxiety on measures of performance efficiency.  相似文献

This article presents a model curriculum in human development for home companions caring for older adult clients in the home care setting. This curriculum is designed to connect cognitive and affective learning by relating stage developmental tasks, as discovered by the home companions through the curriculum, to those experienced throughout life by their clients. Techniques that promote growth and development of both companion and client are explored with a focus on psychosocial dilemmas and constraints imposed by the aging process. The key concepts of life review, long‐term memory within a reminiscence framework, locus of control, autonomy, and relational aspects are addressed from a developmental perspective.  相似文献

Colour is a common feature in computer‐aided learning (CAL), though the instructional effects of screen colour are not well understood. This investigation considers the effects of different CAL study tasks with feedback on posttest performance and on posttest memory of the lesson colour scheme. Graduate students (n=68) completed a computer‐based vocabulary lesson that included either multiple‐choice or constructed‐response study tasks with feedback. Each lesson section used a different colour theme, while the posttest did not use colour. The constructed‐response study task was a little more effective for posttest memory of lesson content but was substantially less effective for posttest memory of the lesson colour scheme. These results show a clear interaction of screen colour and lesson study task, a memory‐context effect. The practical and theoretical implications of these findings are discussed.  相似文献

Two groups of deaf children, aged 8 and 14 years, were presented with a number of tasks designed to assess their reliance on phonological coding. Their performance was compared with that of hearing children of the same chronological age (CA) and reading age (RA). Performance on the first task, short-term recall of pictures, showed that the deaf children's spans were comparable to those of RA controls but lower than CA controls. For the older deaf children, short-term memory span predicted reading ability. There was no clear evidence that the deaf children were using phonological coding in short-term memory when recall of dissimilar items was compared with recall of items with similarly sounding names. In the second task, which assessed orthographic awareness, performance of the deaf children was similar to that of RA controls although scores predicted reading level for the deaf children but not the hearing. The final task was a picture spelling test in which there were marked differences between the deaf and hearing children, most notably in the number of spelling refusals (which was higher for the deaf children in the older group than their RA controls) and the percentage of phonetic errors (which was considerably lower for both groups of deaf children than for any of the hearing controls). Overall these results provide support for the view that deaf children place little reliance on phonological coding.  相似文献

The present study examined phoneme awareness, phonological short term memory, letter knowledge, rapid automatized naming (RAN), and visual–verbal paired associate learning (PAL) as longitudinal predictors of spelling skills in an early phase (Grade 2) and a later phase (Grade 5) of development in a sample of 140 children learning to spell in the opaque Danish orthography. Important features of the study were the inclusion of PAL measures and the fact that the children were followed up to Grade 5. Findings from other orthographies were replicated, in that phonological processing (awareness and memory) and RAN accounted for unique variance in early spelling skills. For later spelling skills, Grade 2 spelling was by far the most powerful predictor. PAL-nonwords was the only measure to explain additional unique variance. It is suggested that PAL-nonwords taps the ability to establish representations of new phonological forms and that this ability is important for the acquisition of orthographic spelling knowledge.  相似文献

The primary aim of the current study was to identify the strongest independent predictors of reading comprehension using word reading, language and memory variables in a normal sample of 180 children in grades 3–5, with a range of word reading skills. It was hypothesized that orthographic processing, receptive vocabulary and verbal working memory would all make independent contributions to reading comprehension. The contributions of reading speed, receptive grammatical skills, exposure to print, visuospatial working memory and verbal learning and retrieval (a measure of longer-term retention) were also investigated. Working memory tasks that required the processing and storage of numerical and spatial material were used. One of the numerical working memory tasks was based on the number span task developed by Yuill, Oakhill, and Parkin British Journal of Psychology, 1989, 80, 351–361. A visuospatial equivalent of that task was developed from the forward Corsi block task [Corsi, Abstracts International, 1973, 34, 891]. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relation with reading comprehension than the memory variables. The strongest independent predictor of reading comprehension was orthographic processing since it captured variance in both word reading, language skills and verbal working memory. The forward Corsi task and performance on a measure of verbal learning and retrieval each made small independent contributions to reading comprehension but the contribution of verbal working memory was not significant. It was concluded that tasks measuring the interplay between short-term and long-term memory, in which new information is combined with information already stored in long-term memory, may better predict reading comprehension measured with the text available than working memory tasks which only have a short-term memory component.  相似文献

The present study was designed to investigate the influence of syntactic complexity on sentence comprehension in Hebrew. Participants were 40 native Hebrew-speaking 5th grade dyslexic and normally reading children aged 10–11 years. Childrens syntactic abilities were tested by three experimental measures: syntactic judgment, a sentence-picture matching task, and a sentence correction task. Each task consisted of sentences composed of five syntactic constructions varying in the level of syntactic complexity (active, passive, conjoined, object-subject relative, and subject-object relative). The length of sentences and the number of propositions in the sentences were controlled. In addition, a wide range of the childrens reading and general abilities (e.g., reading comprehension, phonological awareness, and working memory) was examined. The results indicated that dyslexic readers were less accurate and slower than good readers in all reading tasks and in the tasks on sentence comprehension. The findings suggest that the factor of syntactic complexity seems to be a relatively independent aspect of sentence comprehension. This aspect of sentence comprehension is probably not affected in dyslexic readers. Rather, processing deficit related to phonological and memory impairments of dyslexic children and their ability to process syntactic information is responsible for the difficulties in sentence comprehension.  相似文献

Institutionalized elderly people often appear to live in the past, or in their long‐term memories. The purpose of this study was to determine the effects of playing tapes of Golden Age radio shows, both musical and comedy, on the residents of a nursing home. In particular, the researchers were interested in memory recall, reactions to the memories, and the effects of this activity on involvement in planned nursing home activities. Trivia questions about the same time period were also utilized to determine if discussion of significant historical events in older persons’ lifetimes might be triggers for increased participation and socialization. The study was conducted in a 30‐bed nursing center located 20 miles west of a large midwestern metropolitan area. The participants included 12 women with a mean age of 90 years and of varying levels of cognitive functioning. The Golden Age radio programs were played on a tape recorder for a length of time not exceeding 20 minutes. Trivia questions were verbally posed by the researchers to the study group. Reactions to the Golden Age musical programs indicated that this type of music may evoke memories and encourage reminiscence in the lives of the elderly. The use of trivia is also recommended as a means of stimulating recall of historical and life events. The comedy programs evoked little response in this study, and the researchers feel that additional study in this area could be valuable.  相似文献
