The Knowledge of Memory Aging Questionnaire (KMAQ) measures laypersons' knowledge of normal memory changes and pathological memory deficits in adulthood. In Experiment 1, undergraduate and graduate social work students and social work practitioners completed the KMAQ. Social workers and graduate students were more accurate on the pathological than normal memory aging items, but undergraduate students' knowledge did not differ by question type. Experiment 2 was a conceptual replication where the same pattern of outcomes was obtained using a more heterogeneous sample to increase the ecological validity of the findings. Results confirmed that nonmedical and medical staff at an assisted living facility and health care professionals were more accurate on the pathological than normal memory aging items. Community college and university students' accuracy was similar across question type. Implications for research and the design of education programs to increase awareness of normal and pathological memory deficits in late life are considered. 相似文献

We tested whether changes in attribution processes could account for the developmental differences observed in how children’s use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during which the perceptual fluency of some items was enhanced using a prime. In Experiment 2 (n = 96), participants completed a source recollection judgment on their recognition decisions. Primed items were recognized at a higher rate than unprimed items. However, while young children rely on fluency for all items, older children use fluency only for unfamiliar items. This pattern came together with a reduction in familiarity-based—but not recollection-based—memory responses. 相似文献

The role of categorical versus associative relations in 5-, 7-, and 11-year-old children's true and false memories was examined using the Deese-Roediger-McDermott (DRM) paradigm and categorized lists of pictures or words with or without category labels as primes. For true items, recall increased with age and categorized lists were better recalled than DRM lists. For false items, recall increased with age except for picture lists, there were no differences between categorized and DRM lists and no effect of priming, and there were fewer false memories for pictures than words. Like adults, children's false memories are based on associative not thematic relations, whereas their veridical memories depend on both. This new, developmentally invariant dissociation is consistent with knowledge- and resource-based models of memory development. 相似文献

Two experiments were conducted investigating the role of visual sequential memory skill in the word recognition efficiency of undergraduate university students. Word recognition was assessed in a lexical decision task using regularly and strangely spelt words, and nonwords that were either standard orthographically legal strings or items made from words with internal transposed letters. Symbol memory was evaluated in a recognition procedure in which sequences of three to five unfamiliar complex symbols were presented, each followed by a subsequent array containing the symbols either in the same order or with an order transposition. In Experiment 1, there was no independent contribution of symbol memory to either word or nonword processing independently of the ability to discriminate the symbols from one another. In Experiment 2, although symbol memory made a significant contribution to word recognition independently of symbol discrimination and letter identification for two conditions??long strangely spelt words and short transposed-letter items, the effects were extremely small. It was concluded that non-verbal visual sequential memory skill does not play a central role in underpinning efficiency of word recognition in experienced adult readers. 相似文献

Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers (Experiment 1), but also with young normal readers (Grade 2 and Grade 4 children; Experiment 2) and, even to a larger degree, with readers with dyslexia (Experiments 3 and 4). These experiments suggest that slight increases in inter-letter spacing would improve the readability of texts aimed at children, especially those with dyslexia. 相似文献

错误记忆的发展性逆转是指在一定条件（如DRM范式）下,错误记忆会随着儿童年龄的增长而增长的现象。模糊痕迹理论从记忆痕迹衰退的角度,将错误记忆归因于要点加工和字面加工在记忆衰退中的不同表现;联想激活理论则从记忆的激活出发,将错误记忆的产生归因于项目之间的联想强度。发展性逆转效应为比较儿童和成人在记忆编码、保持和提取过程中的差异提供了新的契机。同时,发展性逆转效应告诉我们,在司法实践中证词的真实性并不因年龄而产生绝对的差别,记忆加工的过程、知识网络的特征等都应该是考量记忆正确性的因素。 相似文献

Two experiments attempted to resolve previous contradictory findings concerning developmental trends in false memories within the Deese-Roediger-McDermott (DRM) paradigm by using an improved methodology--constructing age-appropriate associative lists. The research also extended the DRM paradigm to preschoolers. Experiment 1 (N=320) included children in three age groups (preschoolers of 3-4 years, second-graders of 7-8 years, and preadolescents of 11-12 years) and adults, and Experiment 2 (N=64) examined preschoolers and preadolescents. Age-appropriate lists increased false recall. Although preschoolers had fewer false memories than the other age groups, they showed considerable levels of false recall when tested with age-appropriate materials. Results were discussed in terms of fuzzy-trace, source-monitoring, and activation frameworks. 相似文献

Young Children's Concept of Color and Its Relation to the Acquisition of Color Words 总被引：8，自引：0，他引：8
Nancy N. Soja 《Child development》1994,65(3):918-937
Many children experience great difficulty in learning their first color word. In contrast, once children have learned 1 color word, they learn additional color words more easily. This striking fact raises the question of whether children who do not know color words have conceptual color categories capable of supporting inferences about word meaning. In 3 experiments 2-year-olds were provided with tasks that required them to base inferences on color or to map things onto color. Half the children comprehended at least 1 color word, and the remaining children comprehended none. In all experiments, the children in both groups succeeded on the color tasks. It was argued that children who do not know color words have the conceptual foundation necessary to base inferences on color but have specific constraints against basing inferences about word meaning on color. 相似文献

The purpose of this study was to determine the nature and efficiency of the strategies used by prelingually deafened native signers for the temporary retention of written words with reference to a primary language-coding hypothesis (M. A. Shand, 1982). For the gathering of the data, participants were shown lists of serially presented written target words that they were asked to recognize according to their presentation order from within word pools that contained different types of code-specific distracter words. Three performance dimensions were examined: (a) false recognition of target words, (b) correct recognition of target words, and (c) retention of target word presentation order. Participants were prelingually deafened native signers (n=11, average grade level=8.18 [1.17]) and a hearing control group (n=25, average grade level=9.00 [0.76]). Findings from the analysis of the nature of false recognition and the number of correctly recognized words show convincingly that formationally similar distracter words interfered with the memory performance of the native signers and phonologically similar distracter words with that of the hearing control group. It was concluded that the participants decoded written words into a code reflecting their primary language experience for their temporary retention in working memory. 相似文献

How does developing attentional control operate within visual short‐term memory (VSTM)? Seven‐year‐olds, 11‐year‐olds, and adults (total n = 205) were asked to report whether probe items were part of preceding visual arrays. In Experiment 1, central or peripheral cues oriented attention to the location of to‐be‐probed items either prior to encoding or during maintenance. Cues improved memory regardless of their position, but younger children benefited less from cues presented during maintenance, and these benefits related to VSTM span over and above basic memory in uncued trials. In Experiment 2, cues of low validity eliminated benefits, suggesting that even the youngest children use cues voluntarily, rather than automatically. These findings elucidate the close coupling between developing visuospatial attentional control and VSTM. 相似文献

Children's Understanding of Knowledge Acquisition: The Tendency for Children to Report That They Have Always Known What They Have Just Learned 总被引：1，自引：0，他引：1
Children's attention to knowledge-acquisition events was examined in 4 experiments in which children were taught novel facts and subsequently asked how long they had known the new information. In Experiment 1, 4- and 5-year-olds tended to claim they had known novel animal facts for a long time and also reported that other children would know the novel facts. This finding was replicated in Experiment 2, using facts associated with chemistry demonstrations. In Experiments 3 and 4, children were taught new color words. 5-year-olds, but not 4-year-olds, distinguished between novel and familiar color words, reporting they had not known the novel words before the test session, but they had always known the familiar words. 4-year-olds in Experiment 4 were better able to distinguish novel and familiar color words when the teaching of the novel words was an explicit and salient part of the procedure. 相似文献

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences. 相似文献

Beliefs about naturally occurring transformations were examined in children aged 3 to 6 years in 4 experiments. Experiment 1 tested children's understanding that animals (but not artifacts) predictably get larger over time. Experiment 1a examined whether the results obtained in the first experiment could be attributed to an added memory component on the artifact task. Experiment 2 further examined beliefs about the aging of artifacts. In Experiment 3, color and shape (metamorphosis) changes of animals were investigated. At all ages, children appeared to understand that animals get larger and not smaller with age. While older children and adults allowed for rather dramatic changes in the size and shape of animals over the life span if the alternative involved decreasing in size with age, preschool children were less willing to accept these changes. Taken together, the results of these studies suggest that even young preschool children have 2 conceptual insights about natural transformations: that they are lawful and nonrandom, and that they are domain and mechanism specific. Further, children as young as age 3 are able to go beyond the perceptual appearance of animals in making judgments about transformations caused by growth. Implications for children's understanding of personal and species identity are discussed. 相似文献

As an important metaphor, metaphor of color-related English words regards color domain as source domain, and maps the color domain to non-colored abstract domain. This enables us to understand, think and discuss color-related concept. This paper studies the basic color-related English words through cognitive metaphor. The process of exploring the associative meanings of the color-related English words is in nature to understand the cultural connotation of color-related English words by means of cognitive metaphor under different cultural backgrounds. 相似文献

Previous research has suggested that performance for items requiring memory-binding processes improves between ages 4 and 6 ( J. Sluzenski, N. Newcombe, & S. L. Kovacs, 2006 ). The present study suggests that much of this improvement is due to retrieval, as opposed to encoding, deficits for 4-year-olds. Four- and 6-year-old children ( N = 48 per age) were given objects, backgrounds, and object + background combinations to remember. Younger children performed equivalently to 6-year-olds during a working memory task for all types of memory questions but were impaired during a long-term memory task for the object + background combinations. Furthermore, this deficit was completely due to differences in false alarm rates, suggesting that separate analyses of hits and false alarms may be preferable to corrected recognition scores when studying memory development. 相似文献

Two experiments examined the effects of shifts in the modality on proactive interference in long-term memory. In Experiment 1 subjects learned a 40-word list presented in one of two forms of auditory/visual change—blocked or random. In the blocked conditions, learners were presented half the words in one modality followed by the remaining 20 words in the other modality. Subjects in random conditions also received 20 nouns in each modality, but the presentation was random. Following a delay, all subjects completed an 80-item recognition test. Analysis of these data showed a definite effect (p < .001) for the random change in modality when compared to the blocked presentation. As predicted, distinct reduction in serial position effects was found with the modality of presentation was random. In contrast, the blocked presentation produced two well-defined serial position curves. In Experiment 2 the effects of a shift in the modality of presentation on proactive interference were studied with high and low conceptual rigid subjects. Four similar prose passages were presented with a modality shift taking place in the last passage in a shift condition. Subjects in nonshift conditions were presented the passages exclusively in either the auditory or visual mode. The results showed that a shift in the modality of presentation of a prose passage provided a powerful releaser from proactive interference. The superior performance of rigid thinkers regardless of experimental group membership was explained in terms of organizational memory strategies. 相似文献

In four experiments, the effect of sequential exposure to a series of five novel flavors on the subsequent neophobic response
of water-deprived rats to those flavors when they were presented simultaneously was examined. After a list-test interval of
30 min and a list-interstimulus interval of 10 sec, the rats generally consumed more of the first and last flavors presented
in the initial sequence. This finding was taken to reflect the existence of primacy and recency effects. Experiment 1 provided
evidence that successive contamination can occur between flavors in the initial list, making subsequent recognition of later
flavors in the list more difficult. However, this effect was overcome by presentation of water between each flavor during
the list exposure. Experiments 2 and 4 showed that primacy was not a necessary result of successive contamination in this
procedure, by demonstrating that increasing the interstimulus interval between list items decreased the size of the primacy
effect. This result suggests that rats’ memory for serially presented items may be controlled by mechanisms different from
those typically implicated in the human verbal memory literature. In Experiment 3, the question of whether the testing procedure
adopted here could have introduced sources of artifactually produced serialposition effects was explored, but no such influence
was found. 相似文献
