We investigated the role of age and school type on clustering and switching in verbal fluency tasks (VFTs) with Brazilian children. The children were administered unconstrained, phonemic and semantic VFTs with a duration of 150 or 120 s, respectively. Both age and school type influenced all variables and in terms of performance over time. Older children and private school students outperformed the remainder of the sample, with the first 30 s of each VFT usually being the most productive. Although the size of the clusters produced did not differ between groups, the types of clusters did show some variations, with semantic clusters being the most frequent. Our results revealed strong correlations between switching ability and word production in all three VFTs. In conclusion, the executive functions known as planning and cognitive flexibility play a crucial role in word production by organising and facilitating the recall of lexical information from memory. 相似文献

Cognitive bias refers to a well-established finding that individuals who suffer from certain clinical problems (e.g., depression, anxiety, posttraumatic stress disorder, substance abuse, etc.) selectively attend to, remember, and interpret events relevant to their condition. Although a body of literature exists that has tried to examine this phenomenon, most existing explanations are mentalistic and mediational. In this paper we offer a behavior-analytic account of cognitive bias, its development, and how it may contribute to maintenance of clinical problems. This account is based on establishing operations or motivating events, verbal processes, and relational responding. Clinical and future research implications are also discussed. 相似文献

Although considerable progress has been made in improving the acquisition of expressive verbal communication in children with autism, research has documented that a subpopulation of children still fail to acquire speech even with intensive intervention. One variable that might be important in facilitating responding for this nonverbal subgroup of children is the use of antecedent orienting cues. Using a multiple baseline design, this study examined whether individualized orienting cues could be identified, and whether their presentation would result in the production of verbal expressive words. The results showed that this antecedent stimulus control procedure produced improvements in responding to verbal models in all of the children, and subsequent gains in speech for some of the children. Theoretical and applied implications of orienting cues as they relate to antecedent stimulus control for children with autism are discussed. 相似文献

We assessed whether 2 preschoolers with autism learned to discriminate between the sounds of musical instruments more rapidly than the spoken names of the instruments. After the children learned the sound‐object relations more rapidly than the name‐object relations, we then evaluated a prompt‐delay procedure for transferring stimulus control from the sounds to the names of the instruments. The prompt‐delay procedure facilitated the acquisition of name—object relations for both children. 相似文献

Topographically similar verbal responses may be functionally independent forms of operant behavior. For example, saying yes or no may have different functions based on the environmental conditions in effect. The present study extends previous research on both the assessment and acquisition of yes and no responses across contexts in children with language deficits and further examined the functional independence of topographically similar responses. All participants in the present study acquired yes and no responses within verbal operants (e.g., mands). However, generalization of the responses across novel verbal operants (e.g., tacts to intraverbals) did not occur without additional training, thus supporting Skinner's (1957) assertion of functional independence of verbal operants. 相似文献

Teigen and Brun have suggested that distinct from their numerical implications, most probability phrases are either positive or negative, in that they encourage one to think of reasons why the target event will or will not occur. We report two experiments testing our hypotheses that (a) the direction of a phrase can be predicted from properties of its membership function, and (b) this relation is invariant across contexts, and (c) —originally formulated by Teigen and Brun (1999)—that strong modifiers intensify phrase directionality. For each phrase, participants encoded membership functions by judging the degree to which it described the numerical probabilities 0.0, 0.1, …, 1.0, and also completed sentences including the target phrase. The types of reasons given in the sentence completion task were used to determine the phrase's directionality. The results support our hypotheses (a) and (b) regarding the relation between directionality and the membership functions, but we found only limited support for hypothesis (c) regarding the effects of modifiers on directionality. A secondary goal, to validate an efficient method of encoding membership functions, was also achieved. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

The present paper reports the results of an experimentation that explores the cognitive dimension of gesture involved in many situations of social communication. The method is based on a protocol structured in four experimental modalities, with video sequences. The results from 82 subjects suggest that the role of this component of nonverbal behavior exceeds the apparent transmission of information. It clarifies the verbal speech of the locutor, and also allows to share his own representations, and to direct those of the interlocutor. This impact is all the more effective as the visual-spatial aptitudes of the later are high. 相似文献

Intermittent explosive disorder (IED) is the sole psychiatric diagnostic category for which aggression is a cardinal symptom. IED focuses on physical aggression, but researchers have argued for the inclusion of verbal aggression (VA) (e.g., arguing, threatening) as a part of the IED criteria set. The utility of VA in identifying clinically relevant aggression, however, is unknown. IED participants were compared to individuals without a marked history of physical aggression, but who report frequent (two or more times a week) VA, and non-aggressive personality-disorder individuals on behavioral and self-report measures of aggression, self-report measures of related constructs (e.g., anger, affective lability), and a clinician assessment of psychosocial impairment. Both the IED and VA groups were more aggressive, angry, and clinically impaired than personality-disorder individuals, while the IED and VA groups did not differ from each other on these measures. These results support the clinical importance of frequent VA for future iterations of the IED criteria set. 相似文献
