Imitative play behavior of children: The importance of model distinctiveness and prior imitative training

The frequency of play behaviors of nursery school and second grade subjects (N = 116) who were imitative of one of two models depended upon the extent to which the two models were previously distinguished by the proportion of reinforcement each delivered, and whether reinforcement delivery was contingent upon imitative behavior. A model, high in distinctiveness and also involved in prior imitative training, engendered reliably more imitations than models high (or low) in distinctiveness but involved in nonimitative (or imitative) training.     

Laterality effects with visual perception of

Using the paradigm denoting a contralateral relationship between visual field and brain hemisphere, laterality effects with music notation and dots were investigated. Two groups of readers of advanced piano music were selected, one good, one poor. Each group participated in two visual half-field experiments, one using random dot patterns and the other using musical chords. Significant opposite field effects were found for the two kinds of stimuli across reading groups, the left field for dots and the right field for chords. With dots, a significant sex effect emerged, with males superior to females across groups. The only significant group difference appeared in the chord experiment, in which the good group was superior. A practice effect also was found only with chords. Results suggest that the left hemisphere is more important for recognition of music notation than the right.     

Assessing psycholinguistic orientation and decoding strategies for remedial and nonremedial readers

Remedial readers (8 to 9 year olds) were compared with nonremedial readers of the same age with younger children (6 to 7 year olds) in terms of their acceptance of a psycholinguistic approach vs. a decoding approach to reading, and in terms of the strategies they reported for word attack. Neither remedial nor nonremedial readers (except for a few older nonremedial readers) indicated willingness to skip words in a sentence, but remedial readers were less willing to skip over letters in a word, a psycholinguistic strategy that might allow them to find and use letter patterns to determine an unknown word. They also showed a heavy emphasis on phonic and a narrower range of potential strategies than did other children of the same age.     

Leader Member Exchange in Leaders’ Support for Voice: Good Relationships Matter in Situations of Power Threat

While previous research underscores the role of leaders in stimulating employee voice behaviour, comparatively little is known about what affects leaders’ support for such constructive but potentially threatening employee behaviours. We introduce leader member exchange quality (LMX) as a central predictor of leaders’ support for employees’ ideas for constructive change. Apart from a general benefit of high LMX for leaders’ idea support, we propose that high LMX is particularly critical to leaders’ idea support if the idea voiced by an employee constitutes a power threat to the leader. We investigate leaders’ attribution of prosocial and egoistic employee intentions as mediators of these effects. Hypotheses were tested in a quasi-experimental vignette study (N = 160), in which leaders evaluated a simulated employee idea, and a field study (N = 133), in which leaders evaluated an idea that had been voiced to them at work. Results show an indirect effect of LMX on leaders’ idea support via attributed prosocial intentions but not via attributed egoistic intentions, and a buffering effect of high LMX on the negative effect of power threat on leaders’ idea support. Results differed across studies with regard to the main effect of LMX on idea support.     

A 1-year follow-up of an experimental study of a self-management arthritis programme with an added exercise component of clients with osteoarthritis of the knee

The aim was to assess the self-efficacy and health outcomes of an adopted Arthritis Self-Management Programme (ASMP) among osteoarthritic knee sufferers in Hong Kong at 1 year. An experimental study with 95 participants assigned randomly to the intervention (n=45) or control group (n=50). Seventy-seven (81.1%) participants joined at least one out of three follow-ups in the 12 month period. Participants in the intervention group received a 6-week ASMP with an added exercise component in two general clinics. Outcome measures included arthritis self-efficacy (ASE) and health outcomes including pain and fatigue rating, self-rated health, daily activities limitation and number of unplanned arthritis-related medical consultations. Mean change (12 months minus baseline) and the effect size of the outcome measures were calculated by Mann-Whitney U test and nQuery Advisor 4.0. At 12 months, there were significant reductions of current pain (p=0.0001), pain at night (p=0.001), pain during walking (p=0.01) and number of unplanned arthritis-related medical consultations (p=0.03) and a significant increase in ASE for pain (p=0.01) and other symptoms (p=0.02) and self-rated health (p=0.04) among the intervention group but not for the control group. However, there were similarities in outcome measures of pain while switching from a sitting to a standing position, fatigue rating and physical functional limitation (p=0.15; p=0.22 and p=0.91, respectively) for both groups. Our findings add to the evidence that the modified arthritis empowering programme improved perception of control of osteoarthritis and three health outcomes after 12 months of treatment.     

Stationäre Rehabilitation alkoholabhängiger Patienten

Systemic therapy concepts are widely used in therapy and rehabilitation of alcohol addictive patients. Although very useful in practice, evaluation studies are rare. Adequate evaluation strategies should be developed and implemented. This study was realized in a clinical rehabilitation centre (Hirtenstein, Allgäu/Germany), whose systemic concept is characterized by patient's wideranged possibilities of choice concerning therapy measures and therapy goals, the activation of social and personal resources, the development of an individually appropriate life-style, the training of desired competencies, and an offer for marital and family therapy. The evaluation is based on a repeated measures design without control group. The instruments and constructs of the evaluation are: F-SOZU (perceived social support), IIP (perceived interpersonal problems), MLDL (quality of life), SOC (sense of coherence), and an assessment sheet for personal resources (RI). Patients (n= 44) reported increased personal ressources as well as an increased level of quality of life. Perceived social support and the sense of coherence changed only moderately. Scaling of treatment satisfaction and goal attainment at the end of the rehabilitation program resulted in high positive scores. Patients reported only positive, no negative treatment side effects. The results indicate the usefulness of systemic and resource oriented concepts in the rehabilitation of alcohol addictive patients.
