Knowing minds: Culture and perceptions of mental state access

How does culture influence the ways in which individuals reflect upon their knowledge of others’ mental states? We addressed this question in a two‐study cross‐cultural investigation examining perceptions of mental state access in the United States and Japan. Study 1 (n = 100) revealed that American participants reported greater mental state access than did Japanese participants. Study 2 (n = 146) showed that both Americans and Japanese perceived greater access to the mental states of a close friend relative to a casual friend and that the observed cultural differences in perceived mental state access to a close friend’s mental states were mediated by how much access was considered appropriate. Overall, the results indicate that culturally variable norms specifying appropriate levels of mental state access play an important role in how individuals estimate their knowledge of other people’s minds in close relationships.     

Stress exposure and stress generation in child and adolescent depression: a latent trait-state-error approach to longitudinal analyses

In 2 longitudinal studies of negative life events and depressive symptoms in adolescents (N = 708) and in children (N = 508), latent trait-state-error structural equation models tested both the stress generation hypothesis and the stress exposure hypothesis. Results strongly suggested that self-reports of depressive symptoms reflect the influence of a perfectly stable trait factor as well as a less stable state factor. Support emerged for both the stress generation model and the stress exposure model. When the state depression factor was modeled as predicting stress, support for the stress generation model appeared to increase with age. When the trait depression factor was modeled as the predictor of stress, support for the stress generation model did not vary with the child's age. In both models, support for the stress exposure remained relatively constant across age.     

Categorization of sounds

The authors conducted 4 experiments to test the decision-bound, prototype, and distribution theories for the categorization of sounds. They used as stimuli sounds varying in either resonance frequency or duration. They created different experimental conditions by varying the variance and overlap of 2 stimulus distributions used in a training phase and varying the size of the stimulus continuum used in the subsequent test phase. When resonance frequency was the stimulus dimension, the pattern of categorization-function slopes was in accordance with the decision-bound theory. When duration was the stimulus dimension, however, the slope pattern gave partial support for the decision-bound and distribution theories. The authors introduce a new categorization model combining aspects of decision-bound and distribution theories that gives a superior account of the slope patterns across the 2 stimulus dimensions.     

Opening up the circle: next steps in process group work in Clinical Pastoral Education (CPE)

This article applies systems-centered theory (SCT) to the small process group experience in Clinical Pastoral Education (CPE) by exploring six key questions: 1) What is the purpose of the small process group in CPE? 2) Is there an alternative to getting stuck in the "hot seat" dynamic? 3) Do we (clergy) always have to be nice? 4) Is there life beyond personal story telling? 5) Does the authority issue ever go away? 6) How much difference is too much difference? The article includes vignettes to illustrate theory.     

Dichotic Perception of Mandarin Tones by Chinese and American Listeners

The dichotic perception of Mandarin tones by native and nonnative listeners was examined in order to investigate the lateralization of lexical tone. Twenty American listeners with no tone language background and 20 Chinese listeners were asked to identify dichotically presented tone pairs by identifying which tone they heard in each ear. For the Chinese listeners, 57% of the total errors occurred via the left ear, indicating a significant right ear advantage. However, the American listeners revealed no significant ear preference, with 48% of the errors attributable to the left ear. These results indicated that Mandarin tones are predominantly processed in the left hemisphere by native Mandarin speakers, whereas they are bilaterally processed by American English speakers with no prior tone experience. The results also suggest that the left hemisphere superiority for native Mandarin tone processing is similar to native processing of other tone languages.     

Social Control of Health Behaviors in Marriage1

Married couples (N= 69) reported on their use of social control strategies in attempting to modify each other's health behaviors, as well as their affective and behavioral responses to experiencing health‐related social control. Experiencing more negative social control was associated with the tendency to engage in potentially health‐compromising behaviors, whereas experiencing positive social control was associated with attempts to engage in the desired behavior. Most associations between experiencing social control and the target's behavioral responses could be accounted for, at least partially, by the target's affective responses to the social control attempts. These results suggest that current conceptualizations of the health‐relevance of social control are in need of revision. Implications of these results for social control measurement and theory are discussed.     

Development and Risk Behavior Among African American, Caucasian, and Mixed-race Adolescents Living in High Poverty Inner-city Neighborhoods

Youths growing up in low-income inner-city neighborhoods are at substantial risk for initiating substance use, violent behavior, and sexual intercourse at early ages; these risk behaviors continue at comparatively high rates through adolescence. Hopelessness has been implicated as a risk factor for these behaviors. In this paper, we consider how race influences this process. African Americans form a demographic minority within the United States, but they are often the majority within inner-city neighborhoods. For Caucasians, the opposite typically holds. Mixed-race populations form a minority within both contexts. Using longitudinal data, we examine the relationship between race and risk behaviors in several impoverished inner-city neighborhoods where African Americans form the distinct majority and Caucasians and people of mixed racial heritage form a small minority. We also consider how race moderates the relationship between hopelessness and risk behavior. Our findings show that compared to Caucasian or mixed-race adolescents, African American adolescents are less likely to engage in risk behaviors, and that hopelessness has a less important impact on their behaviors.
