Previous work employing graph theory and nonlinear analysis has found increased spatial and temporal disorder, respectively, of functional brain connectivity in schizophrenia. We present a new method combining graph theory and nonlinear techniques that measures the temporal disorder of functional brain connections. Multichannel electroencephalographic data were windowed and functional networks were reconstructed using the minimum spanning trees of correlation matrices. Using a method based on Shannon entropy, we found elevated connection entropy in gamma activity of patients with schizophrenia; however, gamma connection entropy remained elevated in patients with schizophrenia even after a reduction in symptoms due to treatment with antipsychotics. Our results are consistent with several possibilities: (1) aberrant functional connectivity is epiphenomenal to schizophrenia, (2) aberrant functional connectivity is a central feature but antipsychotics reduce symptoms by an independent mechanism, or (3) connection entropy is not an appropriately sensitive measure of brain abnormalities in schizophrenia. 相似文献

Lexical-semantic access is affected by the phonological structure of the lexicon. What is less clear is whether such effects are the result of continuous activation between lexical form and semantic processing or whether they arise from a more modular system in which the timing of accessing lexical form determines the timing of semantic activation. This study examined this issue using the visual world paradigm by investigating the time course of semantic priming as a function of the number of phonological competitors. Critical trials consisted of high or low density auditory targets (e.g., horse) and a visual display containing a target, a semantically related object (e.g., saddle), and two phonologically and semantically unrelated objects (e.g., chimney, bikini). Results showed greater magnitude of priming for semantically related objects of low than of high density words, and no differences for high and low density word targets in the time course of looks to the word semantically related to the target. This pattern of results is consistent with models of cascading activation, which predict that lexical activation has continuous effects on the level of semantic activation, with no delays in the onset of semantic activation for phonologically competing words. 相似文献

How can we be more successful in persuading others and increase the odds of behavioral compliance? We argue that when a verbal influence strategy is embedded in a nonverbal style that fits its orientation, this boosts the strategy's effectiveness, whereas a misfit attenuates its impact. In field-experiment 1, agents tried to persuade participants in buying a candybox by using an approach-oriented strategy (Door-In-The-Face, DITF). An eager nonverbal style increased the impact of the DITF, whereas vigilant nonverbal cues rendered it ineffective. Conversely, field-experiment 2 showed that an avoidance-oriented strategy (Disrupt-Then-Reframe) benefited from being presented in a vigilant, rather than an eager nonverbal style, which similarly attenuated its impact. Hence, eager nonverbal cues promote the effectiveness of approach-oriented influence strategies whereas vigilant cues do the opposite and increase the impact of avoidance-oriented influence strategies. 相似文献

Abstract Employing an extended case method ethnography ( Burawoy 1998 ), the researcher joined five new members forming a spiritualist's group under the leadership of an experienced advocate. Over a period of eighteen months, the researcher attended all the group's activities and events. Data were collected to reflexively interrogate the process theory of conversion proposed by Lewis Rambo (1993) . The data revealed conversion to be a multifaceted and dynamic process of cognitive change, mediated by structural, and contextual forces. The results provide a reconceptualization of Rambo's theory, presenting a theoretical expansion of the model emphasizing its mechanisms of action. The paper details the composition of the “Interaction‐Commitment” mechanism, operationalized within four submechanisms emanating from Rambo's roles, rituals, rhetoric, and relationships. This longitudinal study shows that most of the hard work toward conversion occurs before any formal interaction with a conversion advocate. Conversion operates most effectively under conditions of cognitive economy wherein the belief path follows a path of least cognitive expenditure. 相似文献

Mood congruence effects have long been studied in younger adults, but not in older adults. Socioemotional selectivity theory (SST) suggests that mood congruence could operate differently in older adults. One hundred and nineteen younger and 78 older adults were randomly assigned to sad or neutral mood inductions, using combined Velten and music induction procedures. Results indicated that during sad mood induction both older and younger adults showed enhanced recall of sad words on delayed word list recall task and in autobiographical memory. However, only older adults displayed mood congruence effects on lexical ambiguity and lower recall of positive words in the word list task. Results provided partial support for developmental effects on mood congruence derived from SST. 相似文献

Three children with autism were taught to identify pictures of objects. Their speed of acquisition of receptive speech skills was compared across two conditions. In the cue-value condition, a compound audiovisual stimulus was presented after correct responses and again when a primary reinforcer was delivered after a 5-s delay; in the response-marking condition, a second stimulus was presented after both correct and incorrect responses, but not prior to the primary reinforcer. In both conditions primary reinforcement was delayed for 5 s. Although the children learned receptive speech skills in both conditions, acquisition was faster in the cue-value condition. 相似文献

Category coherence and category-based property induction 总被引:3,自引:0,他引:3
One important property of human object categories is that they define the sets of exemplars to which newly observed properties are generalized. We manipulated the causal knowledge associated with novel categories and assessed the resulting strength of property inductions. We found that the theoretical coherence afforded to a category by inter-feature causal relationships strengthened inductive projections. However, this effect depended on the degree to which the exemplar with the to-be-projected predicate manifested or satisfied its category's causal laws. That is, the coherence that supports inductive generalizations is a property of individual category members rather than categories. Moreover, we found that an exemplar's coherence was mediated by its degree of category membership. These results were obtained across a variety of causal network topologies and kinds of categories, including biological kinds, non-living natural kinds, and artifacts. 相似文献
