Randomized trial of a meditation-based stress reduction program and cognitive behavior therapy in generalized social anxiety disorder

Mindfulness-based stress reduction (MBSR) has been reported to reduce anxiety in a broad range of clinical populations. However, its efficacy in alleviating core symptoms of specific anxiety disorders is not well established. We conducted a randomized trial to evaluate how well MBSR compared to a first-line psychological intervention for social anxiety disorder (SAD). Fifty-three patients with DSM-IV generalized SAD were randomized to an 8-week course of MBSR or 12 weekly sessions of cognitive-behavioral group therapy (CBGT). Although patients in both treatment groups improved, patients receiving CBGT had significantly lower scores on clinician- and patient-rated measures of social anxiety. Response and remission rates were also significantly greater with CBGT. Both interventions were comparable in improving mood, functionality and quality of life. The results confirm that CBGT is the treatment of choice of generalized SAD and suggest that MBSR may have some benefit in the treatment of generalized SAD.     

Ethnophaulisms and exclusion: the behavioral consequences of cognitive representation of ethnic immigrant groups

Ethnophaulisms are the words used as slurs to refer to ethnic immigrant outgroups. This article explores the effects of these cognitive representations of ethnic immigrant groups on exclusion behavior directed toward these immigrant groups. Using archival data spanning a 150-year period of American history, the results of these analyses provide a sobering picture of the effects of the cognitive representation of immigrants: a century and a half of thinking about ethnic immigrant groups in a simplistic and negative manner and a corresponding tendency to exclude those immigrant groups from the receiving society. The implications of these results for theoretical approaches to intergroup relations are considered.     

Family emotion expressivity,emotion regulation,and the link to psychopathology: Examination across race

Research has established links between parental emotion socialization behaviours and youth emotional and psychological outcomes; however, no study has simultaneously compared these relations for White, Black, and Asian individuals. In this study, emerging adults identifying as White (n= 61), Black (n= 51), or Asian (n= 56) retrospectively reported on parents’ emotion socialization behaviours during childhood, existing emotion regulation (ER) skills, and current psychopathology symptoms. Asian participants reported fewer positive displays of emotions in their families during childhood than White and Black participants. Despite this difference, low expression of positive emotions in families during childhood did not relate to negative outcomes for Asian participants but was linked for White and Black participants. Overall, Asian participants reported more difficulties with ER than Black or White participants, and relations between ER difficulties and psychopathology varied by racial group. The findings emphasize the need to consider race when conducting research on emotion functioning with families and highlight emotion dysregulation as a potential treatment target for White, Black, and Asian individuals.     

A Model of Students' Decimal Computation Procedures

A model that describes the construction and execution of decimal computation procedures is presented. Our hypothesis is that students compute by relying solely on syntax-based rules; semantic knowledge has no effect on performance. To test the claim, a model is developed in which computation procedures are viewed as chains of component symbol manipulation rules. The model assumes that students acquire through instruction the individual rules that achieve subgoals in the computation process. The task for the procedural system is to select rules that satisfy each subgoal in sequence. The model specifies the rules of the system and identifies the syntactic features of the task that affect the selection of individual rules at each decision point. It then predicts the relative difficulty of decimal computation items and predicts the procedural flaw that will occur most frequently on each item. Written test and interview data are presented to test the predictions. Concluding comments discuss the nature of students' computation procedures, compare the model with other models of computation performance, and outline how the model might inform instruction.     

Language,cognition, and second language grammaticality judgments

In first language research, there appear to be two predominant positions relating metalinguistic awareness to language development. One suggests that since metalinguistic awareness is related to primary language acquisition (comprehension and production), general cognitive processes perform a limited role in metalinguistic awareness. The other suggests that since metalinguistic awareness is more closely related to secondary language acquisition (reading and writing), a greater role is assumed by general cognitive processes. There have been some indirect attempts to study the role of language and cognition with respect to second language grammaticality judgments. There is growing evidence that metalinguistic awareness is a reliable indicator of developing second language competence. Furthermore, it has been shown that language aptitude is significantly related to metalinguistic awareness. The present study was designed to investigate the statistical relationship between second language grammaticality judgments and selected cognitive and linguistic variables. The variables studied were second language proficiency, second language classroom achievement, first language reading competence, language aptitude, nonverbal intelligence, field dependence-independence, and a written grammaticality judgment test tapping the ability to recognize, and correct, deviance. Subjects were college students in advanced English-as-a-second-language classes. Multivariate statistical techniques were used to determine the relative contribution of linguistic and cognitive variables to the individual variation demonstrated by the learners in their ability to detect deviance in English. The results showed that second language proficiency, second language achievement in the classroom, and language aptitude were significant predictors of the subjects' ability to make grammaticality judgments. First language reading competence was significantly related to subjects' ability to correct deviance. These observations are discussed in the light of: (1) the relationship among cognition, language, and metalinguistic awareness, and (2) the role of metalinguistic awareness in second language acquisition and second language learning.     

Intention to Migrate: A Psychological Analysis1

A sample of 102 male East Indians intending to immigrate to Canada was compared on several personality and nonpersonality variables with a matched sample of 114 Indians who planned to remain in India. A mail questionnaire procedure was used. Discriminant analyses indicated that personality factors alone accounted for 27% of the variance and that inclusion of nonpersonality factors raised this to 38%. The most important variables separating the groups are occupational satisfaction, sensation seeking, interest in world news, and a locus-of-control component. The findings indicate the sizeable role of personality factors in the decision to migrate and illustrate the utility of a multifaceted approach in understanding complex phenomena such as migration.     

Disinhibition in pitch memory

Recognition of the pitch of a tone is disrupted by the interpolation of other tones during the retention interval. The disruptive effect of an interpolated tone varies systematically as a function of its pitch relationship to the tone to be remembered, and is maximal at a 2/3-tone separation. When such a tone is interpolated, the interpolation in addition of a further tone that is 2/3 tone removed from this disruptive tone (and 4/3 tone removed from the tone to be remembered) causes recognition of the first tone substantially to return. When recognition performance is plotted as a function of the pitch relationship between these two interpolated tones, the results accord well with a model assuming mutual inhibitory interactions between pitch memory elements.     

ARTIST: A computer system for creating and running psychology experiments

A flexible computer system for research and teaching experiments in psychology is described. Special features of the system include (1) separate phases for the generation and running of experiments, (2) facilities to control presentation of stimuli according to any factorial design, and (3) different modes of operation depending on the prior knowledge of the users. The system is evaluated both in terms of the range of experiments that can be performed and in terms of the time and effort required to create new experiments or modify old ones. General principles for designing interactive systems are discussed in the light of experiences with this particular system.
