Characterizing the Linguistic Chameleon: Personal and Social Correlates of Linguistic Style Accommodation

Linguistic style accommodation between conversationalists is associated with positive social outcomes. We examine social power and personality as factors driving the occurrence of linguistic style accommodation, and the social outcomes of accommodation. Social power was manipulated to create 144 face‐to‐face dyadic interactions between individuals of high versus low power and 64 neutral power interactions. Particular configurations of personality traits (high self‐monitoring, Machiavellianism and leadership, and low self‐consciousness, impression management and agreeableness), combined with a low‐power role, led to an increased likelihood of linguistic style accommodation. Further, greater accommodation by low‐power individuals positively influenced perceptions of subjective rapport and attractiveness. We propose individual differences interact with social context to influence the conditions under which nonconscious communication accommodation occurs.     

How environmental movement constraints shape the neural code for space

Study of the neural code for space in rodents has many insights to offer for how mammals, including humans, construct a mental representation of space. This code is centered on the hippocampal place cells, which are active in particular places in the environment. Place cells are informed by numerous other spatial cell types including grid cells, which provide a signal for distance and direction and are thought to help anchor the place cell signal. These neurons combine self-motion and environmental information to create and update their map-like representation. Study of their activity patterns in complex environments of varying structure has revealed that this "cognitive map" of space is not a fixed and rigid entity that permeates space, but rather is variably affected by the movement constraints of the environment. These findings are pointing toward a more flexible spatial code in which the map is adapted to the movement possibilities of the space. An as-yet-unanswered question is whether these different forms of representation have functional consequences, as suggested by an enactivist view of spatial cognition.

     

Does harboring hostility hurt? Associations between hostility and pulmonary function in the Coronary Artery Risk Development in (Young) Adults (CARDIA) study.

OBJECTIVE: To examine the cross-sectional association between hostility and pulmonary function (PF) and its consistency across race/ethnicity-gender groups. DESIGN: Data were from the Coronary Artery Risk Development in (Young) Adults (CARDIA) cohort study (N=4,629). Participants were recruited from 4 metropolitan areas in the United States, ages 18-30 years at baseline in 1985-1986, approximately balanced across race/ethnicity (Black, White) and gender. MAIN OUTCOME MEASURES: Main outcome measures were percent predicted values for forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). RESULTS: In full-sample multiple linear regression analyses, each 1 standard deviation (SD) increase in hostility was associated with a 0.66% decrease in FEV-sub-1 (p=.0002) and a 0.60% decrease in FVC (p=.0006). This inverse association of hostility with PF remained after controlling for age, height, current socioeconomic status (SES), participant smoking status, and asthma and is more consistent than that of smoking and PF. In stratified analyses, each 1 SD increase in hostility predicted statistically significant reductions in PF for Black women, White women, and Black men. For White men, hostility showed no statistically significant relation with PF, although the pattern relating hostility to PF was similar to the pattern in the other three groups. Further, both of the post hoc three-way interaction terms for hostility, race/ethnicity, and gender predicting FEV-sub-1 and FVC were nonsignificant. CONCLUSION: PF was inversely associated with hostility across race/ethnicity and gender, independent of age, height, current SES, smoking, and asthma. On the basis of these cross-sectional findings, the authors hypothesize that higher hostility will predict a more rapid decline in PF.     

Community mental health ideology of preprofessional students

Adherence to the ideology of mental health was measured in a cluster sample of preprofessional students in four majors: psychology, social work, rehabilitation and health education. Mean inventory scores for the four groups did not differ significantly.
