Is the sequencing of change processes by stage consistent across health problems? A meta-analysis.

Clinicians and researchers applying the transtheoretical model (J. O. Prochaska, C.C. DiClemente, & J.C. Norcross, 1992) to health promotion often assume that relationships of processes and stages observed in smoking cessation can be generalized to other problems. A reanalysis of 47 cross-sectional studies determined that use of change processes varies by stage, but the sequencing of processes is not consistent across health problems. In smoking cessation, cognitive processes were used in earlier stages than were behavioral processes. In exercise adoption and diet change, use of behavioral and cognitive processes increased together. Results for substance abuse and psychotherapy were less consistent. Substituting new behaviors, making a commitment, considering consequences, seeking information, controlling cues, and using rewards varied most by stage. Future longitudinal studies should assess these processes as potential mediators of lifestyle change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Decomposition of repetition priming components in picture naming.

Cognitive mechanisms underlying repetition priming in picture naming were decomposed in several experiments. Sets of encoding manipulations meant to selectively prime or reduce priming in object identification or word production components of picture naming were combined factorially to dissociate processes underlying priming in picture naming. Experiments 1, 2, and 3 were conducted with Spanish-English bilingual participants and bilingual materials. Experiments 4, 5A, and 5B were single-language experiments in English or Spanish. A simple process model was used to formalize the theoretical predictions and test them across all experiments simultaneously. Object identification and word production processes were selectively influenced in an additive manner, which suggests that the 2 sets of processes are independent and sequential. The patterns of facilitation support a quantitative model of transfer-appropriate processing in which shared processes from encoding to test are the causal basis and speeded processes are the mechanism of facilitation.

Perceived change processes in emotionally focused couples therapy.

Investigated reports from 21 couples (Ss aged 24–50 yrs) of critical change incidents in their marital therapy experience. These reports, which were sorted into 5 categories of change processes, were collected 4 mo after the completion of 8 sessions of therapy. The reports revealed 5 major change processes: expression of underlying feelings by one of the partners leading to change in interpersonal perception, expressing feelings and needs, acquiring understanding, taking responsibility for experience, and finally receiving validation. These empirically derived processes were compared with the theoretically derived processes. Findings demonstrate the importance of studying what clients say about change to enrich the understanding of change processes in marital therapy.

A typology of critical incidents in intergroup dialogue groups.

Latent semantic analysis (Landauer & Dumais, 1997) was used to derive pairwise similarity ratings based on the content of 102 critical incidents (CIs) identified by participants in four intergroup dialogues. The resulting similarity matrix was then analyzed with cluster analysis to identify the content themes of these CIs. The cluster analysis identified three superordinate clusters and nine content themes in the CIs. The three superordinate clusters were labeled: Cognitive, Affective, and Consciousness Raising change processes. The three Cognitive change processes were labeled: (1) Talking At, (2) Talking With, and (3) Facilitating the Conversation. The three Affective change processes were labeled: (1) Working Toward Acceptance, (2) Learning from Others’ Feelings and Experiences, and (3) Reflection on Felt Differences. The three Consciousness Raising change processes were labeled: (1) Having Eyes Opened, (2) Realizations about People, and (3) Personal Engagement. Similarities and differences between these change processes and change processes described in the group counseling literature are discussed.

Syntactic comprehension in Parkinson's disease: Investigating early automatic and late integrational processes using event-related brain potentials.

Parkinson's disease (PD) has been associated with a general impairment of procedures and with an impairment of syntactic procedures in particular. The present study investigated comprehension processes in PD using event-related brain potentials (ERPs). PD patients and controls listened to sentences that were either correct or syntactically or semantically incorrect. The language-related ERP component correlated with semantic processes (N400) was present in both groups. In the syntactic domain, early automatic processes (early negativity) appeared normal in PD, whereas late integrational processes (P600) were modulated by this disease. The present findings suggest that the basal ganglia primarily do not support early automatic syntactic processes during comprehension but rather support processes of syntactic integration.
