We argue that the grammatical diversity observed among the world’s languages emerges from the struggle between individual cognitive systems trying to impose their preferred structure on human language. We investigate the cognitive bases of the two most common word orders in the world’s languages: SOV (Subject–Object–Verb) and SVO. Evidence from language change, grammaticalization, stability of order, and theoretical arguments, indicates a syntactic preference for SVO. The reason for the prominence of SOV languages is not as clear. In two gesture-production experiments and one gesture comprehension experiment, we show that SOV emerges as the preferred constituent configuration in participants whose native languages (Italian and Turkish) have different word orders. We propose that improvised communication does not rely on the computational system of grammar. The results of a fourth experiment, where participants comprehended strings of prosodically flat words in their native language, shows that the computational system of grammar prefers the orthogonal Verb–Object orders. 相似文献

This review was aimed at systematically investigating the treatment efficacy and clinical effectiveness of neurobehavioral
rehabilitation programs for adults with acquired brain injury and making evidence-based recommendations for the adoption of
these rehabilitation trainings. Using a variety of search procedures, 63 studies were identified and reviewed using a set
of questions about research methods, treatments, results and outcomes for the 1,094 participants. The 63 studies included
treatments falling into three general categories: approaches based on applied behavior analysis, interventions based on cognitive-behavior
therapy (CBT), and comprehensive-holistic rehabilitation programs (CHRPs). Considerable heterogeneity exists in the reviewed
literature among treatment methods and within reported sample subjects. Despite the variety of methodological concerns, results
indicate that the greatest overall improvement in psychosocial functioning is achieved by CHRP that can be considered a treatment
standard for adults with behavioral and psychosocial disorders following acquired brain injury. Both approaches based on applied
behavior analysis and CBT can be said to be evidence-based treatment options. However, findings raise questions about the
role of uncontrolled factors in determining treatment effects and suggest the need for rigorous inclusion/exclusion criteria,
with greater specification of theoretical basis, design, and contents of treatments for both interdisciplinary-comprehensive
approaches and single-case methodologies. 相似文献

Objective: The aim of the present study was to compare autonomic activity, pressure-pain thresholds, and subjective assessments of
health and behavior between patients with stress-related illnesses and healthy control subjects.Methods: Twenty sick-listed patients with stress-related illnesses and 20 age- and gender-matched healthy subjects performed tests
of autonomic regulation and algometric tests, and completed questionnaires about physical and mental health and behavioral
patterns.Results: Patients exhibited higher autonomic reactivity to cognitive and physical laboratory tasks (p<0.05), and had lower pressure-pain thresholds in the shoulders and lower back than healthy control subjects (p<0.05). Furthermore, the patients rated considerably poorer health and health behavior than the control subjects (p<0.05).Conclusions: The results indicate an engagement of the autonomic nervous system in stress-related illnesses. Furthermore, they show that
patients with stress-related illnesses experience symptoms of musculoskeletal pain, and it is therefore recommended that assessments
of musculoskeletal pain be incorporated in the clinical examinations and the rehabilitation of patients with stress-related
illnesses. 相似文献

Strategic remembering emerges gradually during the preschool years. Socialization practices, specifically mother–child social interactions, might provide the foundation for the development of skills necessary for effective organization of information in memory. In the current study, 48 mothers and their 40-month-olds were engaged in the process of remembering (i.e., study and recall) categorically related picture stimuli in a laboratory context. Children’s recall was reliably predicted by the way in which mothers structured both the study and recall periods of the deliberate memory task. Specifically, maternal verbal and physical behaviors that focused on organization of items, such as sorting items into distinct groups and providing the name of a category, were most beneficial in supporting children’s memory. Moreover, some mothers employed a number of different mnemonic techniques that emphasized categorical connections among items, suggesting systematic approaches in the manner in which mothers help children to learn effective ways of remembering. 相似文献

Long-term recall is influenced by what originally was encoded as well as by the efficacy of retrieval processes. The possible explanatory role of post-encoding processes by which initially labile memory traces are stabilized and integrated into long-term memory (i.e., consolidated) has received relatively less research attention. In the current research, we examined 3- and 4-year-old children's recall of multi-step event sequences immediately after seeing them modeled as a measure of encoding, 1week later as a measure of the status of the memory trace post-encoding, and 1month later as an assessment of long-term recall. We tested recall of events with three different levels of internal structure and with three different levels of support for retrieval. Measures of the post-encoding status of the memory trace explained significant variance in long-term recall when they were the sole predictors of performance, and they contributed unique variance in long-term recall even after accounting for the variance associated with encoding. The results imply that a complete explanation of forgetting during childhood must include not only roles for encoding and retrieval processes but also roles for post-encoding processes. 相似文献

By reversing the presentation order and frequency of stimuli between two series of trials, we studied how the category scale for visual speed is transferred across stimulus contexts. Participants judged five stimulus speeds, using three categories (slow, moderate, and fast). In Experiment 1, mainly frequent speeds (either low or high) occurred on the initial trials. This manipulation produced divergent preshift ratings for identical stimuli. Although subsequent reversal of stimulus context resulted in a reversal of scales, the adjustment was incomplete: The postshift ratings did not match the comparable preshift ones. In Experiment 2, mainly infrequent speeds were presented initially. Now the preshift ratings coincided, but higher postshift ratings occurred with the frequent high-speed rather than with the frequent low-speed stimuli. We conclude that with transfer into a new context, the spontaneous adjustment of response scale is determined (1) by the preshift primacy and the postshift frequency effects and (2) by the preshift frequency effect extended to the postshift trials. 相似文献

Tense and syntactic processes in agrammatic speech 总被引:3,自引:0,他引:3
This study focuses on inflectional errors in a group of eight, English-speaking people with agrammatism. Subjects were required to provide inflected verbs in declarative sentences and construct negative sentences. The errors made by these speakers are considered in terms of whether they resemble the errors made by children at the Optional Infinitive Stage. Results confirm that the errors differ from those made by children and that a different explanation is required. Explanations offered by Borer and Rohrbacher (1997) and by Friedmann and Grodzinsky (2000) are discussed but are considered inadequate to deal with our data. It is proposed that agrammatic speakers have problems with the implementation of grammar and particularly with syntactic processes such as feature-checking. 相似文献

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation
require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity
of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and
age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving
ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages
in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in
their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had
a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when
given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found
no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability
for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural
innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed
by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological
success. 相似文献
