Improving the quality of parental interaction with very low birth weight children: A longitudinal study using a Mediated Learning Experience model

Cognitive performance of 3-year-old, very low birth weight children (N = 42) was found to be more significantly related to the quality of parent-child interaction than to early measures of cognitive performance or measures of developmental risk such as birth weight and APGAR. The subjects were randomly divided into an intervention and a control group. The intervention group was visited at home, infrequently, by a mediator who identified basic criteria of quality of parent-child interaction and provided the parents with feedback on the quality of interaction with their own children. The intervention procedure continued for 7 months. The extent of a family's participation in the intervention varied depending upon the initial quality of parent-child interaction and the amount of time it took a family to reach criteria. Quality of parent-child interaction and children's cognitive performance were pretested and reassessed 3 years after the intervention. The sample was reduced to 29 due to attrition over time. Parental behavior following the intervention had changed significantly with respect to all criteria. Parents who had received intervention, as compared to the control group parents, provided their children with more behaviors related to focusing attention, exciting and rewarding, expanding children's understanding of the world around them, preplanning and regulating behavior. Three years after the relatively unintensive intervention, parents continued to show significant gains in quality of mediation. Differences were found between parents of Small for Gestational Age (SGA) and Appropriate for Gestational Age (AGA) children in favor of the SGA group. In children's cognitive performance, scores of the intervention group on the Peabody Picture Vocabulary Test (PPVT) were significantly higher than those of the control group. On other cognitive measures, a consistent trend in favor of the intervention group was noted. More children in the control as compared to the experimental group were rated by their parents as having difficulties with language, fine motor, and sociability skills 3 years after the intervention.     

The assessment of analogical thinking modifiability among regular,special education,disadvantaged, and mentally retarded children

The objectives of the current study were (a) to develop a measure of children's analogical thinking modifiability (CATM) based on the Feuerstein, Rand, and Hoffman (1979) theory of dynamic assessment of cognitive modifiability, (b) to compare the performance of groups assumed to be differentially modified by intervention, (c) to compare CATM performance with performance on a conventional test, and (d) to study qualitative changes after a learning process. Subjects were disdvantaged, regular, and special education kindergarten children (N=140), and mentally retarded children (N=20). The CATM was administered together with the Ravens Colored Progressive Matrices (RCPM) in a balanced order. Disadvantaged and regular children achieved higher gain scores than other groups in both none-or-all and partial credit methods (p < 01). The MR and the special education groups showed small gains according to the none-or-all credit method; however, according to the partial credit method, the MR group showed high gains and the special education group a performance decrease. Performance scores on the CATM were higher than on the RCPM, especially in comparison to the B₈-B₁₂ items-differences reach a peak of 61% and 67% for the disadvantaged and regular groups, respectively. Qualitative analysis indicated that form mistakes were most resistant to change, whereas color mistakes were most easy to modify. Results were explained within Feuerstein's theoretical framework of cognitive modifiability. Impaired cognitive functions as well as analytic versus synthetic processes were suggested to explain group differences.This research was supported in part by the Internal Research Fund, Bar-Ilan University. We wish to express our appreciation to the children and their teachers for their participation, to Frida Spanier for teaching and data collection, and to Steve Greenwald for data analysis.     

Therapists’ understandings and experiences of working with clients with problems of addiction: A pilot study using Q methodology

This pilot study aims to increase our understanding of therapists’ subjective attitudes, beliefs, and experiences of working with clients with problems of addiction. The study yielded useful clarifications, arising from the finding that opinions about the nature of addiction support different approaches to therapy. In addition, it seems that diverse or conflicting attitudes and beliefs are likely to impact on the ability of therapists to work together effectively. Another objective was to test the feasibility of using Q methodology in this study and more broadly in qualitative research in psychotherapy. Participants were 13 therapists from a variety of backgrounds and working in a range of agencies. Using Q methodology, four distinctive factors were identified, indicating divergent understandings of addiction. Each factor is shown to be a multifaceted construct which does not correspond to any single theory or therapeutic orientation. It is suggested that the results have significant implications for therapists’ training and supervision. In addition, this study demonstrates the capacity of Q methodology to identify commonalities and diversity in viewpoints which do not conform to a priori conceptualisations. As a pilot study, this paper invites further discussion and research.     

Handedness in a virtual haptic environment: Assessments from kinematic behavior and modeling

This study evaluated hand asymmetries in performance of a dexterous, controlled task under haptic feedback. Participants punctured a virtual membrane with a pushing or pulling movement, using the left or right hand. For pulling movements, the dominant (right) hand exhibited faster average stopping latency and shorter skidding distance. When the kinematic data were fit to a three-phase model previously applied to this task (Klatzky et al., 2013), the right hand exhibited faster force decay attributable to biomechanical factors. Analyses of the aggregated performance measures and model parameters showed that the left and right hands are associated with two different distributions, supporting handedness effects. Furthermore, while the majority of participants expressed right-hand dominance, which was consistent with their self-reported hand preferences, others showed partial or no dominance. This approach could potentially be extended to quantify and differentiate individuals with difficulties in manual behavior due to abnormal motor control (e.g., dyspraxia), progressive deterioration (e.g., Parkinson's syndrome) or improvement (neural regrowth after transplant).
