The present study investigates the impact of first language (L1) structural frequency and L1 lexical accessibility, manipulated via cognate status, on second language (L2) speech production. L1 German–L2 English speakers and L1 English speakers completed a production task containing pre- and post-modified possessive noun phrase (NP) constructions (e.g. The actress’s sofa vs. The sofa of the actress) in which the head nouns were English-German cognates (e.g. sofa) or noncognates. While English prefers pre-modified NPs, German has a strong frequency bias for post-modified NPs. L2 English speakers exhibited higher production accuracy than L1 English speakers on post-modified NP sentences. However, facilitative L1 effects in production latencies were restricted to post-modified NP sentences containing cognates and only developed cumulatively after repeated exposure to post-modified NP sentences. We discuss how cognate status and L1 structural frequency differentially influence the accuracy and timing of choosing between different structural alternatives during L2 production. 相似文献

Positive events are more common (more tokens), but negative events are more differentiated (more types). These observations and asymmetries about the world are consistent with a number of features or biases favouring positive adjectives that have been shown for English. Compared to their opposites, positive adjectives in English are more likely to be unmarked, negated into their opposite, define the entire negative to positive dimension, and occur first in conjunctions with their negative opposite. In this paper we document that these biases have considerable generality, appearing in all or almost all of 20 natural languages. The greater differentiation of negative states is illustrated here by the demonstration that five common nouns describing negative states in English (disgust, risk, sympathy, accident, murderer) have equivalents in most or all of the 20 languages surveyed, but the opposite of these nouns is not lexicalised in most of the 20 languages. 相似文献

Many studies in animals and humans suggest that sleep facilitates learning, memory consolidation, and retrieval. Moreover, sleep deprivation (SD) incurred after learning, impaired memory in humans, mice, rats, and hamsters. We investigated the importance of sleep and its timing in an object recognition task in OF1 mice subjected to 6h SD either immediately after the acquisition phase (0-6 SD) or 6h later (7-12 SD), and in corresponding undisturbed controls. Motor activity was continuously recorded with infrared sensors. All groups explored two familiar, previously encountered objects to a similar extent, both at the end of the acquisition phase and 24h later during the test phase, indicating intact familiarity detection. During the test phase 0-6 SD mice failed to discriminate between the single novel and the two familiar objects. In contrast, the 7-12 SD group and the two control groups explored the novel object significantly longer than the two familiar objects. Plasma corticosterone levels determined after SD did not differ from time-matched undisturbed controls, but were significantly below the level measured after learning alone. ACTH did not differ between the groups. Therefore, it is unlikely that stress contributed to the memory impairment. We conclude that the loss of sleep and the activities the mice engaged in during the SD, impaired recognition memory retrieval, when they occurred immediately after acquisition. The delayed SD enabled memory consolidation during the 6h when the mice were allowed to sleep, and had no detrimental effect on memory. Neither SD schedule impaired object familiarity processing, suggesting that only specific cognitive abilities were sensitive to the intervention. Sleep may either actively promote memory formation, or alternatively, sleep may provide optimal conditions of non-interference for consolidation. 相似文献

Young children experience considerable difficulty in learning their first few color terms. One explanation for this difficulty is that initially they lack a conceptual representation of color sufficiently abstract to support word meaning. This hypothesis, that prior to learning color terms children do not represent color as an abstraction, was tested in two experiments using samples of 25- to 39-month-olds and 20- to 32-month-olds. Children's ability to conceptually represent color and their knowledge of color terms were assessed, and a strong association was found between the ability to make inferences based on color and the comprehension of color words. Children who did not comprehend color terms were unsuccessful at a conceptual task that required them to represent color as a property independent of the particular objects that displayed it. The results suggest that the initial absence of an abstract representation of color contributes to the difficulty that young children encounter when first learning color words. 相似文献

The experiments described in the lead articles by Kowalski and Zimiles and by O'Hanlon and Roberson examine factors that lead to color term acquisition. These experiments touch on the debate regarding the relative contributions of language and concepts in word learning. In this reflection, we examine how conclusions concerning the debate depend deeply on the particular task presented to children, and we propose an alternative approach to studying color term acquisition. 相似文献

What is the source of the mutual exclusivity bias whereby infants map novel labels onto novel objects? In an intermodal preferential looking task, we found that novel labels support 10-month-olds’ attention to a novel object over a familiar object. In contrast, familiar labels and a neutral phrase gradually reduced attention to a novel object. Markman (1989, 1990) argued that infants must recall the name of a familiar object to exclude it as the referent of a novel label. We argue that 10-month-olds’ attention is guided by the novelty of objects and labels rather than knowledge of the names for familiar objects. Mutual exclusivity, as a language-specific bias, might emerge from a more general constraint on attention and learning. 相似文献

Westerners tend to judge themselves positively unless their failure relative to others is obvious, in which case they tend to distance themselves from outperforming others. Whether this tendency to self-enhance in social-comparison situations is universal or culture-bound is hotly debated. Rather than construe self-enhancement as either universal or culture-bound, we propose that its effects depend on the cultural mindset that is salient at the moment of self-reflection. A cultural mindset is a mental representation containing culture-congruent content, procedures, and goals. We focused on individual and collective mindsets, using language as an unobtrusive mindset prime and predicting that people would be more self-enhancing when an individual mindset was made salient by using English than when a collective mindset was made salient by using Chinese. Three studies supported this hypothesis. Chinese students self-enhanced (rating themselves as better than others and distancing themselves from outperforming others) more when primed with an individual mindset. 相似文献

Spatial short-term memory performance was examined in relation to participants’ strategies. A total of 20 adult participants viewed and reproduced sequences of locations that varied in length (five, six, seven, or eight locations) and spatial separability (a manipulation of the configurations). In trial-by-trial self-reports, participants described five types of strategies. Chunking the spatial sequences into groups of three or four locations was the sole strategy associated with increased accuracy. Participants demonstrated considerable variability in the strategies that they selected, suggesting that cognitive resources are allocated to strategy selection, execution, and monitoring in the spatial span task. Spatially separable sequences were more accurately recalled than nonseparable sequences, independent of strategic grouping, suggesting two levels of grouping in the spatial span task. 相似文献

In this article three viewpoints on the relation of body and language are discussed: the poststructuralist viewpoint of Judith Butler, the phenomenological viewpoint of Maurice Merleau-Ponty and the postmodernist viewpoint of Jean-François Lyotard. The reason juxtaposing for these three accounts is twofold. First, the topic requires a combination of post-structuralist and phenomenological insights, and second, the accounts are supplementary. Butler's account raises questions that can be answered with the help of Merleau-Ponty's work. Lyotard's anthropology of the inhuman offers a perspective of finitude that is missing in the other two. The aim of the article is to outline the necessary ingredients of an adequate conception of the speaking embodied subject. 相似文献

This study tested the ability of a Border Collie, Chaser, to learn the syntax and semantics of sentences consisting of three elements of grammar, a prepositional object, verb, and direct object. Understanding of the syntax of the sentences required that Chaser emit responses consistent with three elements of grammar sentences, such as to ball take Frisbee. Understanding of the semantics of the sentences required that Chaser respond correctly when the meanings of the sentences were changed by reversing positions of the prepositional object and the direct object in the sentence, such as to Frisbee take ball. Chaser's understanding of the sentences was tested in three different scenarios: (a) when multiple and familiar objects were used in the syntax command sentence, (b) when novel objects were used in the syntax command sentence (novel in the sense that objects had not been used during training), and (c) when vision of objects was not possible at the time the syntax command was verbalized. Findings were statistically significant in all three scenarios. Successful findings were attributed to Chaser's intensive training in her first three years of life. Analysis of the data revealed that Chaser's successful understanding of the syntax sentences required the processing and retention of two sound-object mappings (names-objects) into memory, along with simultaneous judgments concerning which object to take to the other – that is, working memory. These two types of cognitive abilities, memory storage and working memory, raise the bar in terms of our expectations of a dog's potential ability to understand verbal communications. We propose that Chaser's understanding of our three elements of grammar sentences represents a giant leap in her referential understanding of language. 相似文献
