There is a common-sense view of language, which is held by Wittgenstein, Strawson Dummett, Searle, Putnam, Lewis, Wiggins, and others. According to this view a language consists of conventions, it is rule-governed, rules are conventionalised, a language is learnt, there are general learning mechanisms in the brain, and so on. I shall call this view the ‘ordinary language’ view of language. Chomsky’s attitude towards this view of language has been rather negative, and his rejection of it is a major motivation for the development of his own theory. In this paper I shall review Chomsky’s long-standing criticisms. I shall show that (1)Chomsky’s argument does not constitute a dismissal of the ‘ordinarylanguage’ view of language, (2) Chomsky’s conclusions about language do not follow from his argument, and (3) the ‘ordinary language’ view actually points to a promising way for us to understand the true nature of language and mind. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

An interactive model of perfectionism, perceived weight status, and self-esteem was tested on 342 female undergraduates to predict bulimic symptoms. Using a longitudinal design, the authors tested the model on data collected at 2 points: the spring of participants' senior year of high school and during participants' first year of college. The authors hypothesized and found that self-esteem moderates the interaction between perfectionism and perceived weight status in predicting bulimic symptoms. Women who are high in perfectionism and who consider themselves overweight exhibit bulimic symptoms only if they have low self-esteem (i.e., if they doubt they can attain their high body standards). High self-esteem women with the same diathesis-stress conditions are less likely to exhibit bulimic symptoms. These findings clarify the role of perfectionism in bulimic symptomatology.  相似文献

This study compared scores on future time perspective of 50 female prison inmates who were participating in a vocational training program within the Julia Tutwiler Prison. There was no control group. Zimbardo's measure of future time perspective, administered a year earlier, was associated with success or failure in the program. Associations of future time perspectives with education, age, and ethnicity were investigated. An analysis of covariance between the 21 graduates and 16 dropouts while controlling for education was significant. Despite the incomplete design, some implications are of interest.  相似文献

Low‐SES couples have limited resources to manage the chronic and acute stressors with which they are disproportionately faced. Although these couples are at greater risk for negative individual and relationship outcomes, evaluations of the impact of couple relationship education (CRE) in low‐SES couples have been plagued by methodological problems, most notably challenges associated with recruitment and retention. We review the literature on challenges couples face associated with low‐SES, as well as on recruitment, retention, and CRE in low‐SES, ethnic minority populations. We illustrate some of these challenges in a case study of CRE for low‐SES couples transitioning to parenthood. In this pilot study, 21 couples were recruited from a community health clinic and randomized to either an experimental treatment condition (EXP;= 11) or a treatment‐as‐usual control condition (TAU;= 10). This study sought to mitigate documented challenges with recruitment and retention: We leveraged community partnerships, attempted to build and maintain strong relationships with study participants, provided incentives for assessments as well as intervention meetings, and attempted to reduce potential barriers to enrollment and retention. Nonetheless, we had low rates of recruitment and retention. We integrate these findings and experiences with our review of previous work in this area. We make recommendations for future CRE research and practice that have potential implications for public policy in this area.  相似文献

We propose a model to measure risk in a prisoner's dilemma based on Coombs' (1973) re‐parameterization of the game as an individual risk decision‐making task that chooses between a gamble of cooperation and another gamble of defection. Specifically, we propose an index, r, to represent the risk associated with cooperation relative to defection. In conjunction with Rapoport's (1967) index of cooperation (K), our formulation of risk allows us to construct games that vary in risk (as indexed by r) while controlling for cooperativeness (as indexed by K). Following utility analysis that models risk seeking as a convex utility function and risk averse as a concave function, we predict that risk‐seeking people cooperate more in games that the cooperation choice is more risky, whereas risk‐averse people cooperate more in games that the cooperation choice is less risky. In the three studies that we varied game parameters, used different measures of risk orientation and prosocial orientation and used different experimental procedures, we found robust results supporting our predictions. Theoretical analysis of our formulation further suggests that risk and cooperativeness of a prisoner's dilemma game is not entirely independent. Games that have a higher cooperativeness index are necessarily more risky. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

We argue that consumers with high self-brand connections (SBC) respond to negative brand information as they do to personal failure — they experience a threat to their positive self-view. After viewing negative brand information, high (vs. low) SBC consumers reported lower state self-esteem. Consumers with high SBC also maintained favorable brand evaluations despite negative brand information. However, when they completed an unrelated self-affirmation task, they lowered their brand evaluations the same as low SBC consumers. This finding suggests that high SBC consumers' reluctance to lower brand evaluation might be driven by a motivation to protect the self rather than the brand.  相似文献

The goal of this study was to identify diverse profiles of Asian American women's and men's adherence to values that are salient in Asian cultures (i.e., conformity to norms, family recognition through achievement, emotional self-control, collectivism, and humility). To this end, the authors conducted a latent profile analysis using the 5 subscales of the Asian American Values Scale-Multidimensional in a sample of 214 Asian Americans. The analysis uncovered a four-cluster solution. In general, Clusters 1 and 2 were characterized by relatively low and moderate levels of adherence to the 5 dimensions of cultural values, respectively. Cluster 3 was characterized by the highest level of adherence to the cultural value of family recognition through achievement, whereas Cluster 4 was typified by the highest levels of adherence to collectivism, emotional self-control, and humility. Clusters 3 and 4 were associated with higher levels of depressive symptoms than Cluster 1. Furthermore, Asian American women and Asian American men had lower odds of being in Cluster 4 and Cluster 3, respectively. These findings attest to the importance of identifying specific patterns of adherence to cultural values when examining the relationship between Asian Americans' cultural orientation and mental health status.  相似文献

Aim: The purpose of this systematic review was to examine research utilizing single subject research designs (SSRD) to explore the effectiveness of interventions designed to increase parents' ability to support communication and social development in children with autism spectrum disorders (ASDs). Method: Included studies were systematically assessed for methodological quality (Logan et al., 2008; Smith et al., 2007) and intervention effects. Data examining participant characteristics, study methodology, outcomes, and analysis were systematically extracted. Results: Eleven SSRD parent-training intervention studies examining 44 participants with ASD were included. Overall, the studies were of moderate quality and reported increases in parent skills and child language and communication outcomes. Interpretation: The results supported by improvement rate difference (IRD) analysis indicated several interventions demonstrated positive effects for both parent and child outcomes. However, limited generalization and follow-up data suggested only one intervention demonstrated parents' accurate and ongoing intervention implementation beyond training.  相似文献

A prospective, behavioral high-risk design provided a theoretically guided examination of vulnerability to first onset of bipolar spectrum disorder based on the Behavioral Approach System (BAS) model. Adolescents (ages 14-19) at an "age of risk" for bipolar disorder onset were screened on BAS sensitivity by interviewers blind to current symptoms, lifetime history, and family history of psychopathology. Participants were selected with high versus moderate levels of BAS sensitivity and administered a lifetime diagnostic interview. Those with a bipolar spectrum disorder, psychosis, or hypomanic episode with onset prior to the BAS sensitivity assessment were excluded. High BAS (n = 171) and moderate BAS (n = 119) sensitivity participants in the final sample completed baseline measures of symptoms, goal-setting, and reward responsiveness and were followed prospectively with semistructured diagnostic interviews every 6 months. Consistent with the vulnerability hypothesis of the BAS model of bipolar disorder, high BAS participants had a greater likelihood, and shorter time to onset, of bipolar spectrum disorder than moderate BAS participants across an average of 12.8 months of follow-up (12.9% vs. 4.2%), controlling for baseline depressive and hypomanic symptoms, and family history of bipolar disorder. High reward responsiveness on a behavioral task and ambitious goal-striving for popular fame and financial success (but not impulsivity) also predicted first onset of bipolar spectrum disorder controlling for the covariates and BAS risk group, and ambitious goal-striving partially mediated the BAS risk group effect. We discuss implications of the findings for the BAS model of bipolar disorder and early intervention efforts.  相似文献
