Speakers sometimes encounter utterances that have anomalous linguistic features. Are such features registered during comprehension and transferred to speakers’ production systems? In two experiments, we explored these questions. In a syntactic-priming paradigm, speakers heard prime sentences with novel or intransitive verbs as part of prepositional-dative or double-object structures (e.g., The chef munded the cup to the burglar or The doctor existed the pirate the balloon). Speakers then described target pictures eliciting the same structures, using the same or different novel or intransitive verbs. Speakers overall described targets with the same structures as the primes (abstract syntactic priming), but more so when the primes and targets had the same novel or intransitive verbs (a lexical boost), an effect that was only observed when the novel words served as the verbs in both the prime and target sentences. Such a lexical boost could only manifest if speakers formed associations between the verbs and structures in the primes during comprehension, and if these associations were then transferred to their production systems. We thus showed that anomalous utterance features are not ignored but persist (at least) in speakers’ immediately subsequent production. 相似文献

Since the publication of Clark and Chalmers' Extended Mind paper, the central claims of that paper, viz. the thesis that cognitive processes and cognitive or mental states extend beyond the brain and body, have been vigorously debated within philosophy of mind and philosophy of cognitive science. Both defenders and detractors of these claims have since marshalled an impressive battery of arguments for and against “active externalism.” However, despite the amount of philosophical energy expended, this debate remains far from settled. We argue that this debate can be understood as answering two metaphysical questions. Yet prominent voices within the debate have assumed that there is a tight relationship between these two questions such that one question can be answered via the other. We defend an alternative ‘wide’ view, whereby mentality is understood as constituted by wide social and cultural factors. Our wide view entails that the two metaphysical questions are separate and should be kept distinct. This suggests that active externalism as understood by prominent voices within that debate requires dissolution, rather than solution. However, if the debate were instead understood as only focusing on the second of the two questions, then there could be a possible future for this debate. 相似文献

Previous psycholinguistic research has shown that a variety of contextual factors can influence the interpretation of syntactically ambiguous structures, but psycholinguistic experimentation inherently does not allow for the investigation of the role that these factors play in natural (uncontrolled) language use. We use regression modeling in conjunction with data from the British National Corpus to measure the amount and specificity of the information available for disambiguation in natural language use. We examine the Direct Object/Sentential Complement ambiguity and the closely related issue of complementizer use in sentential complements, and find that both ambiguity resolution and complementizer use can be predicted from contextual information. 相似文献

Psychologists, particularly those influenced by the work of B. F. Skinner, played a major part in the development of behavioral pharmacology in the 1950s and 1960s. Revolutionary changes in pharmacology and psychiatry, including the discovery of powerful therapeutic agents such as chlorpromazine and reserpine, had produced a surge of interest in drug research. Pharmaceutical companies began hiring psychologists with operant conditioning backgrounds so as to compete successfully in the search for new drugs. Psychologists, most of whom were skilled in the behavior-analytic approach, started to assume prominent positions as authors and editors for the Journal of Pharmacology and Experimental Therapeutics as its emphasis on behavior increased. This also proved true with the other publications founded to deal with the popularity of behavioral pharmacology. Especially important were contributions by B. F. Skinner, Peter B. Dews, and Joseph V. Brady. 相似文献

The assumed ordinal relationship between seriously considering, planning, and attempting suicide in the 1999 Youth Risk Behavior Survey was examined by constructing a trajectory that identified all possible response patterns among the four questions measuring suicidal activity. Statistical analysis tested for differences in frequency of risk behaviors across levels of the trajectory. Overall, the trajectory provided insight to the progression of adolescent suicidal activity and demonstrated usefulness as a measure of suicidal intent. Significant differences between means of dependent variables at each level of the normative trajectory supported the hypothesis that frequency of risk behaviors increases monotonically with successive suicidal thought and behavior. 相似文献

The effects of aging and dorsal hippocampal lesions: performance on spatial and nonspatial comparable versions of the water maze 总被引:3,自引:0,他引:3

Aged intact and young hippocampal-lesioned rats show similar deficits on the spatial water maze. However, this does not necessitate that the source of these deficits in the aged animals is due to hippocampal damage. These water maze deficits may arise from other aging factors such as changes in thermoregulation, muscle fatigue, swim ability, and response to stress. Consequently, it is imperative to examine the performance of aged rats on a comparable nonhippocampal version of this task. Past attempts to develop a hippocampus-independent version of the water maze were confounded because these tasks were easier (i.e., the rats spent much less time swimming in the water) than the spatial versions of the task. The current study examined performance on a hippocampus-independent task comparable in difficulty to the spatial water one. Middle-aged (16-m) and old (25-m) male F344 rats were given sham or dorsal hippocampus lesions and tested on both a spatial and a nonspatial water maze. The middle-aged rats with hippocampal lesions were impaired on the spatial task but not on the nonspatial task. Conversely, aged animals showed a similar impairment on both types of water maze tasks. Additionally, hippocampal lesions exacerbated the age-related impairment on both tasks. These findings indicate that caution must be used when interpreting the results of water maze tasks for aged animals. 相似文献
