Large-scale neural network for sentence processing 总被引:4,自引:0,他引:4

Our model of sentence comprehension includes at least grammatical processes important for structure-building, and executive resources such as working memory that support these grammatical processes. We hypothesized that a core network of brain regions supports grammatical processes, and that additional brain regions are activated depending on the working memory demands associated with processing a particular grammatical feature. We used functional magnetic resonance imaging (fMRI) to test this hypothesis by comparing cortical activation patterns during coherence judgments of sentences with three different syntactic features. We found activation of the ventral portion of left inferior frontal cortex during judgments of violations of each grammatical feature. Increased recruitment of the dorsal portion of left inferior frontal cortex was seen during judgments of violations of specific grammatical features that appear to involve a more prominent working memory component. Left posterolateral temporal cortex and anterior cingulate were also implicated in judging some of the grammatical features. Our observations are consistent with a large-scale neural network for sentence processing that includes a core set of regions for detecting and repairing several different kinds of grammatical features, and additional regions that appear to participate depending on the working memory demands associated with processing a particular grammatical feature. 相似文献

The experiments reported in this article used a delayed same/different sentence matching task with concurrent measurement of eye movements to investigate the nature of the plausibility effect. The results clearly show that plausibility effects are not due to low level lexical associative processes, but arise as a consequence of the processing of the earliest or most basic form of sentential meaning. In fact, when sentential implausibility and lexical association are varied simultaneously, it is only sentential implausibility that exerts an effect. Effects of implausibility occur rapidly—sometimes parafoveally—and are localised in the regions of the sentence where the implausibility occurs, suggesting an incremental interpretive process progressing on a roughly word-by-word basis. It is suggested that plausibility effects result from the operation of a heuristically-driven process of sentential interpretation. This appears to behave in a ‘modular’ fashion, despite being influenced by real world knowledge and probabilities.Particular thanks are due to Ken Forster for kindling the ideas which led to much of this work and to Merrill Garrett for posing impossible challenges, which, probably to everyone’s surprise, could in fact be met. I am also much indebted to Claire Boissiere, Emma Clayes, Clare Dobbin, Alan Kennedy, Julie-Ann Marshall, Ashley Murray, and Murray Rowan for their collaboration in this research. 相似文献

This paper proposes a brain-inspired cognitive architecture that incorporates approximations to the concepts of consciousness, imagination, and emotion. To emulate the empirically established cognitive efficacy of conscious as opposed to non-conscious information processing in the mammalian brain, the architecture adopts a model of information flow from global workspace theory. Cognitive functions such as anticipation and planning are realised through internal simulation of interaction with the environment. Action selection, in both actual and internally simulated interaction with the environment, is mediated by affect. An implementation of the architecture is described which is based on weightless neurons and is used to control a simulated robot. 相似文献

The paper examines potential origins of automatic (i.e., unconscious) attitudes toward one’s marital partner. It tests the hypothesis that early experiences in conflict-of-interest situations predict one’s later automatic inclination to approach (or avoid) the partner. A longitudinal study linked daily experiences in conflict-of-interest situations in the initial months of new marriages to automatic evaluations of the partner assessed four years later using the Implicit Associations Test. The results revealed that partners who were initially (1) treated less responsively and (2) evidenced more self-protective and less connectedness-promoting “if-then” contingencies in their thoughts and behavior later evidenced less positive automatic partner attitudes. However, these factors did not predict changes in love, satisfaction, or explicit beliefs about the partner. The findings hint at the existence of a “smart” relationship unconscious that captures behavioral realities conscious reflection can miss. 相似文献

An instrument designed to measure components of two distinct alcoholism aftercare treatments was developed and evaluated for reliability and validity. Trained judges reliably rated audiotaped samples of coping skills and interactional group therapy sessions. Coping skills groups engaged in significantly more education and skill training, problem solving, and role playing. Interactional groups showed more interpersonal learning, expression/exploration of feelings, and here-and-now focus. Groups that employed more education and skill training, less expression and exploration of feelings, and less her e-and-now focus were associated with fewer members reporting subsequent drinking-related problems. None of the ratings of group activities was related to abstinence. 相似文献

The authors examined differences between young adults (n = 25) and healthy older adults (n = 48) in reaction time and the relations between center of pressure (COP) and center of mass (COM) motions during rapid initiation and termination of voluntary postural sway. Older adults were divided into low and high falls-risk groups based on Physiological Profile Assessment scores of sensorimotor function. Low falls-risk older adults had slower reaction times during anteroposterior sway initiation and decreased COP–COM separation during anteroposterior and medialateral sway initiation and anteroposterior continuous voluntary sway compared with young adults. High falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP–COM separation during sway initiation and continuous voluntary sway in the anteroposterior and medialateral directions compared with young adults. Compared with low falls-risk older adults, high falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP–COM separation during medialateral continuous voluntary sway. Reaction time and COP–COM measures significantly predicted group status in discriminant models with sensitivities and specificities of 72–100%. Overall, these findings highlight important associations of age-related declines in sensorimotor function related to an increased risk of falling with slower postural reaction time and reduced postural stability. 相似文献

The Pathological Narcissism Inventory (PNI) is a multidimensional measure of narcissistic pathology. This study examined the factor structure and psychometric properties of the PNI in a sample of Chinese university students in Hong Kong. Eight hundred and thirty-one students completed an online battery of questionnaires assessing narcissistic pathology, self-esteem, unstable sense of self, and maladaptive self-defense strategies. Results replicated the 7 first-order factors and the 2 second-order factors of the PNI. Each of the 7 first-order factors and the 2 second-order factors had good internal consistency. Preliminary findings also supported the concurrent validity of the PNI. The PNI appeared to be a valid measure of narcissistic pathology among Chinese. Findings of this study suggest that the core pathology of pathological narcissism might involve an inflated sense of self-importance that is not substantiated by actual achievement, and bearing this unsubstantiated sense of self-importance renders narcissists highly susceptible to self-deflation when their narcissistic needs are not met. 相似文献

Three studies describe the development, psychometric properties, and potential utility of a new self-report measure, the Circumplex Scales of Interpersonal Values (CSIV). The CSIV was designed to complement other interpersonal circumplex measures that assess interpersonal behavior by efficiently assessing a comprehensive set of agentic and communal values. The eight 8-item scales of the CSIV were shown to have good internal consistency and test-retest reliability and a circumplex structure. The CSIV showed convergent and discriminant validity with measures of interpersonal traits (the Bem Sex Role Inventory; Bem, 1974), interpersonal problems (the Inventory of Interpersonal Problems-Circumplex; Horowitz, 2000), implicit interpersonal motives (the Thematic Apperception Test; see Atkinson, 1958), and interpersonal goals (the Interpersonal Goals Inventory; Dryer &; Horowitz, 1997). Finally, the locations of the MCMI-III (Millon, 1994) personality disorder scales on the CSIV circumplex generally mirrored the locations of personality disorders on other interpersonal circumplex measures. 相似文献

Subjective ratings of physical attractiveness were compared with objective ratings of attractiveness in the prediction of popularity. The relationships between Harter's (1979) Perceived Competency Scale for Children (PCSC) and both popularity and physical attractiveness were also examined. Fifty-three third-grade and 54 fifth-grade children were tested on the Harter scales and on a new 7-item scale of self-perceived attractiveness. Objective attractiveness ratings were provided by 30 other children of the same grades and sex. Popularity was assessed by sociometric nominations and ratings. The results replicated the moderate relationship of objective attractiveness and popularity found in prior studies. Self-perceived attractiveness was unrelated to popularity in third-grade children but was significantly related at the fifth-grade level. Subjective and objective attractiveness were inversely related at the third-grade level but were positively related in fifth graders. Objective attractiveness was unrelated to self-esteem at either grade level but subjective attractiveness predicted self-esteem for all the children. 相似文献
