Modifying automatic approach action tendencies in individuals with elevated social anxiety symptoms

Research suggests that social anxiety is associated with a reduced approach orientation for positive social cues. In the current study we examined the effect of experimentally manipulating automatic approach action tendencies on the social behavior of individuals with elevated social anxiety symptoms. The experimental paradigm comprised a computerized Approach Avoidance Task (AAT) in which participants responded to pictures of faces conveying positive or neutral emotional expressions by pulling a joystick toward themselves (approach) or by moving it to the right (sideways control). Participants were randomly assigned to complete an AAT designed to increase approach tendencies for positive social cues by pulling these cues toward themselves on the majority of trials, or to a control condition in which there was no contingency between the arm movement direction and picture type. Following the manipulation, participants took part in a relationship-building task with a trained confederate. Results revealed that participants trained to approach positive stimuli displayed greater social approach behaviors during the social interaction and elicited more positive reactions from their partner compared to participants in the control group. These findings suggest that modifying automatic approach tendencies may facilitate engagement in the types of social approach behaviors that are important for relationship development.     

Me and my 400 friends: the anatomy of college students' Facebook networks, their communication patterns, and well-being

Is there a trade-off between having large networks of social connections on social networking sites such as Facebook and the development of intimacy and social support among today's generation of emerging adults? To understand the socialization context of Facebook during the transition to adulthood, an online survey was distributed to college students at a large urban university; participants answered questions about their relationships by systematically sampling their Facebook contacts while viewing their Facebook profiles online. Results confirmed that Facebook facilitates expansive social networks that grow disproportionately through distant kinds of relationship (acquaintances and activity connections), while also expanding the number of close relationships and stranger relationships, albeit at slower rates. Those with larger networks estimated that larger numbers of contacts in their networks were observing their status updates, a form of public communication to one's entire contact list. The major function of status updates was emotional disclosure, the key feature of intimacy. This finding indicates the transformation of the nature of intimacy in the environment of a social network site. In addition, larger networks and larger estimated audiences predicted higher levels of life satisfaction and perceived social support on Facebook. These findings emphasize the psychological importance of audience in the Facebook environment. Findings also suggest that social networking sites help youth to satisfy enduring human psychosocial needs for permanent relations in a geographically mobile world--college students with higher proportions of maintained contacts from the past (primarily high school friends) perceived Facebook as a more useful tool for procuring social support.     

BEHAVIORAL TREATMENT FOR PATHOLOGICAL GAMBLING IN PERSONS WITH ACQUIRED BRAIN INJURY

The present investigation examined a behavior‐analytic clinical treatment package designed to reduce the pathological gambling of 3 individuals with acquired brain injury. A prior history of pathological gambling of each patient was assessed via caregiver report, psychological testing, and direct observation of gambling behavior. Using an 8‐week one‐on‐one client—patient format, a treatment program was developed in which the patient learned about the antecedents, consequences, and motivating operations that controlled the emission of gambling behavior. Data were collected on both self‐report of gambling urges and behavior following therapy and during in situ gambling opportunities. The therapy program reduced urges to gamble and actual gambling for all patients. The potential of behavior‐analytic therapy for reducing the pathological gambling of patients with and without brain injury is discussed.     

Everyday conceptions of object fall: explicit and tacit understanding during middle childhood

Adults make erroneous predictions about object fall despite recognizing when observed displays are correct or incorrect. Prediction requires explicit engagement with conceptual knowledge, whereas recognition can be achieved through tacit processing. Therefore, it has been suggested that the greater challenge imposed by explicit engagement leads to elements of conceptual understanding being omitted from prediction that are included in recognition. Acknowledging that research with children provides a significant context for exploring this "omission hypothesis" further, this article reports two studies with 6- to 10-year-olds, each of which used prediction and recognition tasks. Study 1 (N=137) focused on understanding of direction of fall, and Study 2 (N=133) addressed speed. Although performance on the recognition tasks was generally superior to performance on the prediction tasks, qualitative differences also emerged. These differences argue against interpreting explicit level understanding purely in terms of omission of tacit constructs, and the article outlines alternative models that may account for the data.     

Parenting Practices and Adolescent Internalizing and Externalizing Problems: Moderating Effects of Socially Demanding Kin Relations

Association of socially demanding kin relations, mother’s emotional support, behavioral control/monitoring, family organization and psychological control with adolescent’s internalizing and externalizing problems were assessed in 200 economically disadvantaged, African American mothers and adolescents. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s internalizing problems. Demanding kin relations also moderated the association of control/monitoring, family organization, and psychological control, with internalizing. For mothers with more demanding kin relations, increased control/monitoring was associated with increased adolescent internalizing. In comparison, increased control/monitoring was associated with decreased adolescent internalizing for mothers with less demanding kin relations. Negative association of family organization with internalizing was more apparent for mothers with more compared to less demanding kin relations. Positive association of mother’s psychological control with internalizing was more apparent for mothers with more compared to less socially demanding kin relations. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s externalizing problems. Mother’s emotional support and family organization were negatively associated with externalizing. Also, negative association of family organization with externalizing was more apparent for families with more compared to less demanding kin relations. The need for research on the factors associated with negative relation with kin was discussed.     

Four applications of permutation methods to testing a single-mediator model

Four applications of permutation tests to the single-mediator model are described and evaluated in this study. Permutation tests work by rearranging data in many possible ways in order to estimate the sampling distribution for the test statistic. The four applications to mediation evaluated here are the permutation test of ab, the permutation joint significance test, and the noniterative and iterative permutation confidence intervals for ab. A Monte Carlo simulation study was used to compare these four tests with the four best available tests for mediation found in previous research: the joint significance test, the distribution of the product test, and the percentile and bias-corrected bootstrap tests. We compared the different methods on Type I error, power, and confidence interval coverage. The noniterative permutation confidence interval for ab was the best performer among the new methods. It successfully controlled Type I error, had power nearly as good as the most powerful existing methods, and had better coverage than any existing method. The iterative permutation confidence interval for ab had lower power than do some existing methods, but it performed better than any other method in terms of coverage. The permutation confidence interval methods are recommended when estimating a confidence interval is a primary concern. SPSS and SAS macros that estimate these confidence intervals are provided.     

Nodding in dis/agreement: a tale of two cultures

Head movement is commonly used to communicate positive versus negative response. However, whereas in US culture, vertical head movement denotes positivity (nodding to say “yes”) and horizontal head movement is associated with negativity (shaking heads to say “no”), in Bulgaria, this response pattern is reversed, that is, horizontal head movement means “yes” and vertical head movement means “no.” Thus, these two cultures spatially “embody” agreement via different movement directions. We examined the effect of such cultural differences on cognitive processing that has no communicative intent by comparing ratings of likeability, brightness, and positive feeling associated with different color moving dots. Participants followed the dots’ movement with their heads in a 2 (direction: vertical vs. horizontal) by 2 (speed: fast vs. slow) design. We found a two-way country by speed of movement interaction such that Bulgarian participants associated colors with more positive feeling when those were perceived in combination with slower head movement irrespective of movement direction. US participants, on the other hand, rated color dots as better mood-enhancing in combination with faster head movement. There was a similar two-way country by movement speed interaction for likeability ratings but none for brightness. Findings are discussed in terms of variability in gestural meaning and culture-specific embodiment patterns.
