Predictors of Therapist Adherence and Emotional Bond in Multisystemic Therapy: Testing Ethnicity as a Moderator

This study examined the interaction between problem severity and race\ethnicity as a predictor of therapist adherence and family-therapist emotional bond. Data for this study came from a longitudinal evaluation of Multisystemic Therapy (MST) provided by licensed MST provider organizations in community settings. Outcome variables included mid-treatment levels of caregiver report of therapist adherence, changes in caregiver report of therapist adherence over the course of treatment, and overall levels of caregiver-therapist and youth-therapist emotional bond. Hypothesized predictors included race\ethnicity and levels of poly-substance use, externalizing behavior, and youth self-report of delinquency early in treatment as well as pre-treatment number of arrests. Participants were 185 adolescents (M age = 15.35, SD = 1.29) and their caregivers. Of the participating youth, 48 % self-identified as Caucasian, 20 % as African-American, 28 % as Hispanic\Latino, and 4 % as “other.” Two-level Hierarchical Linear Modeling analyses revealed that for Caucasian youth, lower rates of self-reported delinquency were associated with greater increases in caregiver report of therapist adherence over the course of MST. For Hispanic\Latino caregivers, higher externalizing behavior and poly-substance use were associated with reports of lower therapist adherence at mid-treatment and poorer overall levels of emotional bonding with therapists. In contrast, for African-American participants, higher levels of youth externalizing behavior and poly-substance use were associated with higher overall levels of caregiver and youth report of emotional bonding with therapists, respectively. Results provide evidence that race\ethnicity interacts with problem severity in predicting therapist adherence and family-therapist emotional bond within real-world practice settings and suggest possible therapeutic process differences across race.     

Coordinating spatial referencing using shared gaze

To better understand the problem of referencing a location in space under time pressure, we had two remotely located partners (A, B) attempt to locate and reach consensus on a sniper target, which appeared randomly in the windows of buildings in a pseudorealistic city scene. The partners were able to communicate using speech alone (shared voice), gaze cursors alone (shared gaze), or both. In the shared-gaze conditions, a gaze cursor representing Partner A’s eye position was superimposed over Partner B’s search display and vice versa. Spatial referencing times (for both partners to find and agree on targets) were faster with shared gaze than with speech, with this benefit due primarily to faster consensus (less time needed for one partner to locate the target after it was located by the other partner). These results suggest that sharing gaze can be more efficient than speaking when people collaborate on tasks requiring the rapid communication of spatial information.

Accommodating variation: dialects, idiolects, and speech processing

Listeners are faced with enormous variation in pronunciation, yet they rarely have difficulty understanding speech. Although much research has been devoted to figuring out how listeners deal with variability, virtually none (outside of sociolinguistics) has focused on the source of the variation itself. The current experiments explore whether different kinds of variation lead to different cognitive and behavioral adjustments. Specifically, we compare adjustments to the same acoustic consequence when it is due to context-independent variation (resulting from articulatory properties unique to a speaker) versus context-conditioned variation (resulting from common articulatory properties of speakers who share a dialect). The contrasting results for these two cases show that the source of a particular acoustic-phonetic variation affects how that variation is handled by the perceptual system. We also show that changes in perceptual representations do not necessarily lead to changes in production.
