Neighborhood, family, and subjective socioeconomic status: How do they relate to adolescent health?

This study investigated the role of neighborhood, family, and individual subjective socioeconomic status (SES) in predicting adolescent physical health and psychological characteristics. Three hundred fifteen adolescents completed assessments of blood pressure, cortisol, and body mass index (BMI). Results revealed that lower neighborhood SES was associated with higher BMI and lower basal cortisol levels and that these effects persisted after controlling for family SES. Both family SES and neighborhood SES predicted negative psychological characteristics and experiences such as hostility and discrimination. In contrast, only subjective SES predicted positive psychological characteristics. These findings suggest the importance of understanding influences at the individual, family, and neighborhood levels for optimally targeting interventions to reduce health disparities earlier in life.     

Ain’t sure who to blame: Metacognitive influences on appraisal–emotion processes

In this research, we propose that emotions are affected not only by appraisals, but also by a metacognitive sense of confidence versus doubt over the appraisals. Focusing on core-relational themes (CRTs), higher-order appraisals comprising the combined meaning of several appraisals, we predicted and found evidence, over two studies, that the effect of a CRT on the corresponding emotion is stronger if one feels confident about the validity of the CRT compared to feeling doubtful. In Study 1, CRT was manipulated by recall and in Study 2, CRT was manipulated in vivo. Both designs produced consistent support for the hypotheses. These findings demonstrate the need to consider metacognitive processes in understanding the effects of appraisals on emotions.     

“Deafness” effects in detecting alterations to auditory feedback during sequence production

Past research has shown that when discrete responses are associated with a perceptual goal, performers may have difficulty detecting stimuli that are commensurate with that goal. Three experiments are reported here that test whether such effects extend to sequence production. In Experiment 1, participants performed 8-note melodies repeatedly, and on each trial a single tone could be altered with respect to its pitch and/or synchrony with actions. Results suggested a selective deficit of detection when feedback pitch was unchanged and the event was slightly delayed. Experiment 2 showed that this “deafness” to feedback is limited to rhythmic motor tasks that require sequencing, in that similar effects did not emerge when participants produced pitch sequences by tapping a single key repeatedly. A third experiment demonstrated similar results to Experiment 1 when the mapping of keys to pitches on the keyboard was reversed. Taken together, results suggest a selective deafness to response-congruent delayed feedback, consistent with the idea that performers suppress previously planned events during production.
