Research investigating hemispheric asymmetries in meaning selection using homophonic homographs (e.g., bank), suggests that the left hemisphere (LH) quickly selects contextually relevant meanings, whereas the right hemisphere (RH) maintains a broader spectrum of meanings including those that are contextually irrelevant (e.g., Faust & Chiarello, 1998). The present study investigated cerebral asymmetries in maintaining the multiple meanings of two types of Hebrew homographs: homophonic homographs and heterophonic homographs (e.g., tear). Participants read homographs preceded by a biasing, or a non-biasing sentential context, and performed a lexical decision task on targets presented laterally, 1000 ms after the onset of the sentence-final ambiguous prime. Targets were related to either the dominant or the subordinate meaning of the preceding homograph, or unrelated to it. When targets were presented in the LVF/RH, dominant and subordinate meanings, of both types of homographs, were retained only when they were supported by context. In a non-biasing context, only dominant meanings of homophonic homographs were retained. Alternatively, when targets were presented in the RVF/LH, priming effects for homophonic homographs were only evident when meanings were supported by both context and frequency (i.e., when context favored the dominant meaning). In contrast, heterophonic homographs resulted in activation of dominant meanings, in all contexts, and activation of subordinate meanings, only in subordinate-biasing contexts. The results challenge the view that a broader spectrum of meanings is maintained in the right than in the left hemisphere and suggest that hemispheric differences in the time course of meaning selection (or decay) may be modulated by phonology.  相似文献

Research examining links between personality and interest have typically focused on links between measures of the five factor model and Holland’s RIASEC types. However, the five factor model of personality can be divided in to a larger set of narrow domain personality scales measuring facets of the ‘big five’ traits. Research in a number of fields indicates that facet scales are effective for clarifying the relationship between personality and other broad constructs, including academic achievement, job performance, stress and coping, and achievement motivation. In the present study links between personality facets and the RIASEC model were examined using property vector fitting. Obtained results are consistent with previous research suggesting that the use of facet-level personality measures can clarify relations between personality and other constructs, and provides new information linking personality facets and interests. The use of facet-level measures of personality expands the range of personality concepts that can be presented to individuals who are exploring career options.  相似文献

The competitive attachment model of human parsing is a hybrid connectionist architecture consisting of a distributed feature passing method for establishing syntactic relations within the network, and a numeric competition mechanism for resolving ambiguities, which applies to all syntactic relations. Because the approach employs a uniform mechanism for establishing syntactic relations, and a single competition mechanism for disambiguation, the model can capture general behaviors of the human parser that hold across a range of syntactic constructions. In particular, attachment and binding relations are similarly processed and are therefore subject to the very same influences of disambuguation and processing over time. An important influence on the competitive disambiguation process is distance within the network. Decay of numeric activation, along with distributed feature passing through the network structure, has an unavoidable effect on the outcome of attachment and binding competitions. Inherent properties of the model thus lead to a principled explanation of recency effects in the human parsing of both attachment and filler/gap ambiguities.  相似文献

An integrated model of cognitive control in task switching   总被引:2,自引:0,他引:2  
A model of cognitive control in task switching is developed in which controlled performance depends on the system maintaining access to a code in episodic memory representing the most recently cued task. The main constraint on access to the current task code is proactive interference from old task codes. This interference and the mechanisms that contend with it reproduce a wide range of behavioral phenomena when simulated, including well-known task-switching effects, such as latency and error switch costs, and effects on which other theories are silent, such as with-run slowing and within-run error increase. The model generalizes across multiple task-switching procedures, suggesting that episodic task codes play an important role in keeping the cognitive system focused under a variety of performance constraints.  相似文献

Considerable evidence suggests that group interventions are a valuable resource for cancer patients, but few conceptual frameworks are available to guide decisions about which approaches might be most useful for which patients at what phases of illness. This article presents an integrative treatment model for group services. It describes different group interventions geared toward patients at different phases of illness to accommodate the shifting needs and concerns that evolve over the course of the disease. Recommendations are offered concerning further research and model development.  相似文献

Recent theoretical developments in the field of absolute identification have stressed differences between relative and absolute processes, that is, whether stimulus magnitudes are judged relative to a shorter term context provided by recently presented stimuli or a longer term context provided by the entire set of stimuli. The authors developed a model (SAMBA: selective attention, mapping, and ballistic accumulation) that integrates shorter and longer term memory processes and accounts for both the choices made and the associated response time distributions, including sequential effects in each. The model's predictions arise as a consequence of its architecture and require estimation of only a few parameters with values that are consistent across numerous data sets. The authors show that SAMBA provides a quantitative account of benchmark choice phenomena in classical absolute identification experiments and in contemporary data involving both choice and response time.  相似文献

We present an integrated model for the understanding of and the reasoning from conditional statements. Central assumptions from several approaches are integrated into a causal path model. According to the model, the cognitive availability of exceptions to a conditional reduces the subjective conditional probability of the consequent, given the antecedent. This conditional probability determines people's degree of belief in the conditional, which in turn affects their willingness to accept logically valid inferences. In addition to this indirect pathway, the model contains a direct pathway: Availability of exceptional situations directly reduces the endorsement of valid inferences. We tested the integrated model with three experiments using conditional statements embedded in pseudonaturalistic cover stories. An explicitly mentioned causal link between antecedent and consequent was either present (causal conditionals) or absent (arbitrary conditionals). The model was supported for the causal but not for the arbitrary conditional statements.  相似文献

Abstract

Although finding meaning and reestablishing a sense of control following a major loss are important contributors to successful coping, many individuals are unable to restore these adaptive assumptions. Five strategies for reestablishing meaning and control are identified, and it is proposed that the use of these strategies requires cognitive work, the ability to change views and try new perspectives, and flexibility in goal identification. This framework is used to understand why many people fail to find meaning and control following a serious loss. Characteristics of the situation that make it difficult to find meaning and control include the severity and type of the loss. Personal factors that block or impede the restoration of adaptive assumptions include an avoidant coping style, few opportunities to vent, the belief that positive interpretation involves self-delusion, a rigid belief system, and difficulty in disengaging from goals. Interventions to address these blockades and increase successful coping are discussed.  相似文献

This study examined the effectiveness of an integrated model of brief group psychotherapy for treatment of fibromyalgia syndrome, using cognitive behavioral and supportive expressive techniques. In the context of an outpatient, multidisciplinary fibromyalgia treatment program, group psychotherapy was provided to 35 patients with 21 control patients. Pre-post treatment measures of depression, anxiety, fibromyalgia impact, pain, fatigue, and morning tiredness were obtained. Using a quasi-experimental design with validated psychometric instruments, the results showed a significant decrease in pre-versus post treatment measures of depression, fibromyalgia impact, fatigue, and pain for the treatment patients, suggesting that an integrated model of group psychotherapy may have beneficial psychological and functional effects for some patients with fibromyalgia.  相似文献

Research showing that activation of negative stereotypes can impair the performance of stigmatized individuals on a wide variety of tasks has proliferated. However, a complete understanding of the processes underlying these stereotype threat effects on behavior is still lacking. The authors examine stereotype threat in the context of research on stress arousal, vigilance, working memory, and self-regulation to develop a process model of how negative stereotypes impair performance on cognitive and social tasks that require controlled processing, as well as sensorimotor tasks that require automatic processing. The authors argue that stereotype threat disrupts performance via 3 distinct, yet interrelated, mechanisms: (a) a physiological stress response that directly impairs prefrontal processing, (b) a tendency to actively monitor performance, and (c) efforts to suppress negative thoughts and emotions in the service of self-regulation. These mechanisms combine to consume executive resources needed to perform well on cognitive and social tasks. The active monitoring mechanism disrupts performance on sensorimotor tasks directly. Empirical evidence for these assertions is reviewed, and implications for interventions designed to alleviate stereotype threat are discussed.  相似文献

This study replicates, integrates, and extends prior research on the dispositional, contextual, and cognitive antecedents of feedback-seeking behavior. Regression analysis was used to analyze data collected from a sample of salespeople (N = 310) from 2 Fortune 500 companies. The study hypotheses were supported with the following results. First, the individual disposition of learning goal orientation and the contextual factors of leader consideration and leader initiation of structure influenced cognitions about the perceived cost and value of feedback seeking. Second, the strength of the relationship of learning goal orientation with the cost and value perceptions was moderated by the leadership style of the supervisor.  相似文献

To investigate the relationship between worry and sense of humor, the author administered the Worry Domains Questionnaire (WDQ; F. Tallis, M. Eysenck, & A. Matthews, 1992) and the Multidimensional Sense of Humor Scale (MSHS; J. A. Thorson & F. C. Powell, 1993) to 140 undergraduates. Worry was negatively related to sense of humor. Results of a stepwise regression, using the WDQ as the criterion and the MSHS factors as predictors, showed that the humor production factor of the MSHS loaded negatively on Step 1 and the coping with humor factor loaded positively on Step 2. The results are discussed in relation to W. E. Kelly and M. J. Miller's (1999) cognitive model of worry and worry as a coping strategy.  相似文献

Service delivery systems for maltreating parents need to be comprehensive, integrated, and coordinated in order to address the ecological, developmental, and psychotherapeutic needs of maltreating families. This article presents a center-based, intensive model of intervention for multiproblem, maltreating families. The program described addresses the needs of the entire family; incorporates the evaluation and treatment of the child's, as well as the parent's, development; and provides services in a multifamily group milieu. The following interventions are integrated in the treatment approach: (1) family milieu approach, (2) assistance with functioning of the “parental ego,” (3) traditional therapies, and (4) developmental-structuralist approach to parent-child interaction. Challenges encountered and solutions employed in working with maltreating families are discussed. A detailed case study is presented to illustrate the types of interventions used.  相似文献

We describe an activation-based model of word recognition and apply it to the process of resolving the meaning of homographs presented in context. The interpretation of homographs was assessed by asking participants to decide whether a target word was related to the meaning of a sentence containing a homograph. These relatedness decisions varied systematically with the relative frequency of the homograph meanings, delay, and the nature of the sentence context. In the model, it was assumed that orthographic and contextual information combine additively to determine the activation of word meanings, and that the probability of a "related" response is determined by the activation level of the related meaning. The model accurately accounts for all observed effects, as well as their interaction. We conclude that the core process of lexical ambiguity resolution may be quite simple.  相似文献

The current work explores how people make recognition and belief judgments in the presence of obvious repetition primes. In two experiments, subjects received a 200-ms prime ("cheetah"), either before or after reading a trivia question ("What is the fastest animal?") but always before being presented with the target answer ("cheetah"). Results showed that repetition priming decreased "old" claims (Recognition--Experiment 1), while it increased truth claims (Belief--Experiment 2). Furthermore, repetition prime placement affected recognition but not belief. Combined, these results suggest that dissociations in memory performance are a natural outcome of task and processing demands and reflect the dynamic, flexible nature of memory.  相似文献

A group of 60 middle-aged morticians at a professional seminar in the midwestern USA who completed a multidimensional sense of humor scale scored significantly lower than another group of 136 men from other occupations. The difference between the two groups appeared almost entirely on scale items having to do with humor generation or creativity.  相似文献

In three experiments, the meaning activation of ambiguous nouns in novel nominal compounds was investigated. Ambiguous nouns were unbalanced homographs occurring as the second members of the compound. Meaningful interpretations of the compounds were based on either the dominant or the subordinate meaning of the ambiguous noun. In Experiment 1, visually presented novel compounds serving as primes were followed at varying intervals by targets associatively related to distinct meanings of the ambiguous noun. In a lexical decision task, facilitation effects were found only for targets related to the meaning that was relevant for the interpretation of the compound. Experiment 2 showed that interactive activation could not be attributed to differences in semantic relatedness between the first members of compounds and targets. Experiment 3 demonstrated equal intralexical relatedness between members for both types of compounds. It is proposed that interactive activation may facilitate the interpretation of the novel compound. Compatible meaning aspects of the nouns may become more strongly activated, and incompatible meaning aspects may not become activated. The selection of meaning aspects relevant for interpretation would thereby be simplified.  相似文献
