Nine individuals with complex language deficits following left-hemisphere cortical lesions and a matched control group (n = 9) performed speeded lexical decisions on the third word of auditory word triplets containing a lexical ambiguity. The critical conditions were concordant (e.g., coin-bank-money), discordant (e.g., river-bank-money), neutral (e.g., day-bank-money), and unrelated (e.g., river-day-money). Triplets were presented with an interstimulus interval (ISI) of 100 and 1250 ms. Overall, the left-hemisphere-damaged subjects appeared able to exhaustively access meanings for lexical ambiguities rapidly, but were unable to reduce the level of activation for contextually inappropriate meanings at both short and long ISIs, unlike control subjects. These findings are consistent with a disruption of the proposed role of the left hemisphere in selecting and suppressing meanings via contextual integration and a sparing of the right-hemisphere mechanisms responsible for maintaining alternative meanings. 相似文献

The processing of lexical ambiguity in context was investigated in eight individuals with schizophrenia and a matched control group. Participants made speeded lexical decisions on the third word in auditory word triplets representing concordant (coin-bank-money), discordant (river-bank-money), neutral (day-bank-money), and unrelated (river-day-money) conditions. When the interstimulus interval (ISI) between the words was 100 ms, individuals with schizophrenia demonstrated priming consistent with selective, context-based lexical activation. At 1250 ms ISI, a pattern of nonselective meaning facilitation was obtained. These results suggest an attentional breakdown in the sustained inhibition of meanings on the basis of lexical context. 相似文献

This paper contains two studies which set out to examine to what extent attributional style (internal, stable, global) and personality traits predicted happiness and psychiatric symptoms in a normal, non-clinical, population of young people in their early twenties. Two hundred and three participants completed five questionnaires: the Attributional Style Questionnaire (ASQ) (version one & version two), Eysenck Personality Questionnaire, Oxford Happiness Inventory, and Langner 22-Item Measure. Sample 1 (n = 120) completed ASQ version one (in both positive and negative situations) and sample 2 (n = 83) completed ASQ version two (in expanded negative situations). Regressional analysis showed that ASQ (in both versions) was the significant predictor of happiness and mental health accounting for 20% to 38% of variances. The ASQ was significantly associated with extraversion and neuroticism. Further, with happiness and mental health as dependent variables and attributional style, personality traits, and demographic variables as independent variables respectively, extraversion and attributional stability (in positive situations) were the significant predictors of happiness accounting for 59% of the total variance whilst neuroticism and psychoticism were the significant predictors of mental health accounting for 53% of the total variance. The results indicated that optimistic attributional style in positive situations was a stronger predictor of self-reported happiness than mental health and pessimistic attributional style in negative situations was a predictor of both happiness and mental health. Extraverts tended to have optimistic explanatory style for positive outcomes whereas neurotics tended to have pessimistic explanatory style for negative outcomes. 相似文献

Research shows that religion continues to be an important identity marker for new immigrants in the United States. However, immigrant groups differ in the ways they integrate religious and ethnic identities and the emphasis they place on each. In this paper, we argue that majority or minority status of their religious affiliation in the home and host countries is an important, but overlooked, factor in understanding strategies concerning religious and ethnic identities. By comparing two Chinese congregations, a Chinese Buddhist temple and a Chinese Christian church in Houston, Texas, we analyze what happens when an immigrant group moves from majority status in the home country to minority status in the United States (Chinese Buddhists) and when a minority group (Chinese Christians in China) become part of the Christian majority in the United States. We conclude by arguing the importance of going beyond U.S. borders and taking into account factors in their home countries in attempts to understand patterns of adaptation of the new immigrants. 相似文献

The study examined the satisfactions and regrets of midlife parents at a specific family life-cycle milestone, their child’s
graduation from high school. The purpose was to compare mothers’ and fathers’ appraisals of the gains and losses associated
with this developmental transition and turning point in their parenting roles. A total of 260 parents (147 mothers; 113 fathers)
who had a child graduating from high school responded in writing to open-ended questions regarding their satisfactions and
regrets at this stage of their lives. Responses were coded to identify themes salient to these parents. Results indicate that
both mothers and fathers are aware of both the gains and losses at this time in their family life cycle, but they differed
in how they expect to be affected by the transition. Mothers’ responses suggest that they are anticipating and planning for
the transition. Fathers’ responses suggest they are less aware of the personal implications of this family transition and
are less prepared for its emotional impact. 相似文献

In this study we examined the evocative and abative effects of an establishing operation on challenging behavior during classroom instruction for a student with severe disabilities including autism. A prior functional analysis indicated that his challenging behavior was maintained by access to preferred snack items. During classroom instructional sessions these snack items were visible but not available to the student. In other words challenging behavior was placed on extinction during instruction. Immediately prior to instructional sessions the student received either access to snack items or did not receive access to snacks. Access versus no access to snacks prior to instruction was systematically controlled using a multi‐element design. Results demonstrated higher levels of challenging behavior during instruction when the student did not have access to snacks prior to instruction. Very little challenging behavior occurred during instructional sessions when the student had prior access to snacks. Implications for considering the evocative and abative effects of establishing operations when implementing operant extinction in applied settings are discussed.
