ABSTRACT This study examines age-associated changes in retrieval on a picture-naming task, phonemic and semantic fluency tasks, and the Homophone Meaning Generation Test (HMGT). The sample included 152 Hebrew-speaking adults, half young (mean age 22.75) and half old (mean age 76.05). Groups differed on the picture-naming task and on both verbal fluency tasks, but not on the HMGT. Age explained a greater share of the variance than did education level on these three tests, whereas the opposite pattern of results was seen on the HMGT. We suggest that age-related word finding difficulties are attenuated when performance allows for semantic rather than phonological access. 相似文献

ABSTRACT In the present study we tested the possibility that older adults differ from younger adults in their appreciation of metaphoric semantic relations, and that age-related changes occur due to the perception of novel metaphors. In the first experiment 35 younger (mean age?=?23.1) and 35 older adults (mean age?=?75.3) were asked to rate the plausibility of metaphoric, literal, and unrelated word pairs. Relative to young participants, older participants rated fewer expressions as metaphorically plausible. The second experiment was conducted to examine whether the findings of the first experiment could be accounted for by an age-associated difference in the appreciation of metaphors with different levels of familiarity. In the second experiment, 25 younger (mean age?=?24.4) and 25 older adults (mean age?=?77.5) were asked to rate the familiarity level of the plausible metaphoric expressions. Relative to young participants, older participants rated fewer expressions as novel and more expressions as familiar. The results suggest that novelty plays an important role in appreciating the plausibility of semantic relationships, and age-related changes are associated with the appreciation of the novelty of expressions. 相似文献

Children with language impairment (LI) and children with typical development (TD) were assessed by their respective parents using The MacArthur Communicative Development Inventories (Swedish version SECDI) and Greenspan Socio Emotional Growth Chart (GSEGC). The aim was to investigate socio-emotional and language development in children with LI and TD with respect to possible differential patterns and relations between the groups. The results highlight a clear association between language and socio-emotional development. Children with LI were rated similar to young language-matched children with TD, but significantly lower relative to age-matched TD children, particularly concerning symbolic stages of development: the use of linguistic symbols as well as related areas such as symbol play and symbolic mental ability. The results are discussed in light of presumable background factors and possible consequences for children or sub-groups of children with LI. 相似文献

Optimal Bayesian reasoning performance has reportedly been elusive, and a variety of explanations have been suggested for this situation. In a series of experiments, it is demonstrated that these difficulties with replication can be accounted for by differences in participant-sampling methodologies. Specifically, the best performances are obtained with students from top-tier, national universities who were paid for their participation. Performance drops significantly as these conditions are altered regarding inducements (e.g., using unpaid participants) or participant source (e.g., using participants from a second-tier, regional university). Honours-programme undergraduates do better than regular undergraduates within the same university, paid participation creates superior performance, and top-tier university students do better than students from lower ranked universities. Pictorial representations (supplementing problem text) usually have a slight facilitative effect across these participant manipulations. These results indicate that studies should take account of these methodological details and focus more on relative levels of performance rather than absolute performance. 相似文献

An exploratory study of linguistic–colour associations across languages in multilingual synaesthetes
《Quarterly journal of experimental psychology (2006)》2013,66(7):1343-1355
In one of the most common forms of synaesthesia, linguistic–colour synaesthesia, colour is induced by stimuli such as numbers, letters, days of the week, and months of the year. It is not clear, however, whether linguistic–colour synaesthesia is determined more by higher level semantic information—that is, word meaning—or by lower level grapheme or phoneme structure. To explore this issue, we tested whether colour is consistently induced by grapheme or phoneme form or word meaning in bilingual and trilingual linguistic–colour synaesthetes. We reasoned that if the induced colour was related to word meaning, rather than to the acoustic or visual properties of the words, then the induced colours would remain consistent across languages. We found that colours were not consistently related to word meaning across languages. Instead, induced colours were more related to form properties of the word across languages, particularly visual structure. However, the type of inducing stimulus influenced specific colour associations. For example, colours to months of the year were more consistent across languages than were colours to numbers or days of the week. Furthermore, the effect of inducing stimuli was also associated with the age of acquisition of additional languages. Our findings are discussed with reference to a critical period in language acquisition on synaesthesia. 相似文献

In English, new information typically appears late in the sentence, as does primary accent. Because of this tendency, perceivers might expect the final constituent or constituents of a sentence to contain informational focus. This expectation should in turn affect how they comprehend focus-sensitive constructions such as ellipsis sentences. Results from four experiments on sluicing sentences (e.g., The mobster implicated the thug, but we can't find out who else) suggest that perceivers do prefer to place focus late in the sentence, though that preference can be mitigated by prosodic information (pitch accents, Experiment 2) or syntactic information (clefted sentences, Experiment 3) indicating that focus is located elsewhere. Furthermore, it is not necessarily the direct object, but the informationally focused constituent that is the preferred antecedent (Experiment 4). Expectations regarding the information structure of a sentence, which are only partly cancellable by means of overt focus markers, may explain persistent biases in ellipsis resolution. 相似文献

Most theories of reference assume that a referent's saliency in the linguistic context determines the choice of referring expression. However, it is less clear whether cognitive factors relating to the nonlinguistic context also have an effect. We investigated whether visual context influences the choice of a pronoun over a repeated noun phrase when speakers refer back to a referent in a preceding sentence. In Experiment 1, linguistic mention as well as visual presence of a competitor with the same gender as the referent resulted in fewer pronouns for the referent, suggesting that both linguistic and visual context determined the choice of referring expression. Experiment 2 showed that even when the competitor had a different gender from the referent, its visual presence reduced pronoun use, indicating that visual context plays a role even if the use of a pronoun is unambiguous. Thus, both linguistic and nonlinguistic information affect the choice of referring expression. 相似文献

The “principle of linguistic relativity” holds that, by way of grammatical categorization, language affects the conceptual representations of its speakers. Formal gender systems are a case in point, albeit a particularly controversial one: Previous studies obtained broadly diverging data, thus giving rise to conflicting conclusions. To a large extent, this incoherence is related to task differences and methodological problems. Here, a priming design is presented that avoids previous problems, as it prevents participants from employing gender information in a strategic manner. Four experiments with German native speakers show priming effects of the prime's grammatical gender on animate and nonanimate targets, an effect for the prime's biological gender on animate targets, but no effect for the prime's biological gender on nonanimate targets, and thus speak against an effect of language on thought for German gender. 相似文献

The degree to which the typical age of acquisition (AoA) of words and word frequency have separable influences on verbal production tasks has been strongly debated. To examine the overlap between these factors in verbal fluency tasks, the performance of Alzheimer's disease (AD) patients (N?=?34) and normal elderly controls (N?=?36) was compared on semantic (e.g., vegetables) and letter (e.g., words that begin with F) fluency tasks. These comparisons revealed that words generated for the semantic fluency task had an earlier AoA while words generated for the letter fluency task had a higher word frequency. Differences in AoA between AD patients and controls were larger for semantic than letter fluency. These results suggest that AoA has an effect on verbal production that is independent of word frequency and that AoA has a semantic locus. 相似文献

This article presents the results of a quasi-experimental study that examined the relation between the metacomprehension (i.e., understand/do not understand) and evaluative (i.e., agree/disagree) response to a simple one-sentence statement to compare the relative timing in which these two responses are generated in the course of sentence processing. In the study, participants were asked to provide metacomprehension and evaluative judgements to simple one-sentence assertions, and their response times were measured. Two of the main findings are: first, the response time for the evaluative judgement is faster than the response time for the metacomprehension judgement and, second, the faster response time of the evaluative judgement relative to the metacomprehension judgement is more pronounced either when they are not sure about whether they understand a statement or when they feel they do not understand a statement. The findings are analysed in relation to a multiple constraint satisfaction model of sentence comprehension to generate a possible processing model of a simple one-sentence assertion underlying the generation of metacomprehension and evaluative responses. 相似文献
