Computer‐Based Intervention with Coaching: An Example Using the Incredible Years Program

Increases in personal computer ownership and Internet use patterns provide a potential avenue for dissemination of evidence‐based prevention and treatment interventions. The authors describe the implementation of a psychoeducational intervention (the Incredible Years parenting program, which is designed to promote behavioral change in parents and children) using a hybrid model combining computer‐ and web‐based delivery with professional intervention via phone calls, electronic messages, and home visits. The model attempted to simulate many of the parent training methods shown to be successful in the original program. The intervention was implemented with 90 Head Start families who reported elevated levels of child behavior problems. Of the 45 families offered the intervention in the final year of the project, 37 (82%) completed at least half the program and 34 (76%) completed the entire intervention using procedures refined in light of the initial year's experience. These participants reported high achievement of their self‐determined goals and were highly satisfied with the intervention. The combination of technology with professional coaching represents a potential model for adapting and disseminating evidence‐based interventions.     

The moral of the story: The importance of applying an ethics lens to the teaching of positive psychology

In a short-time positive psychology has progressed into a scientific and multidisciplinary field of enquiry. It is now necessary for positive psychology to develop clear practice standards which will be collectively endorsed and upheld by members and those undergoing training in positive psychology. Teachers of positive psychology are in a prime position to disseminate ethical knowledge. Moreover, the objectives of ethics and positive psychology are closely aligned in their focus on achieving optimal outcomes; hence, the pairing of the two is ideal. Consequently, it would be ironic if positive psychology did not explicitly embrace ethical standards in guiding those training for a future in positive psychology. As a professional entity, positive psychology needs to provide more direction and encouragement for teachers, students, scholars and practitioners of positive psychology, and in time, this should be codified and discussed in positive psychology university degrees to promote consistency among its future members.     

The benefits and risks of strategic genealogy and dichotomy

This contribution to a symposium on Manuel A. Vásquez’ More Than Belief: A Materialist Theory of Religion (2011) looks at the role of genealogy in the book. Vásquez reviews a range of authors (from Plato to Tweed) to contextualize his view that the study of religion should place greater emphasis on embodiment, practices, and emplacement. The resulting sequence of paraphrases is highly dichotomized; some illustrate the 'dominant canon' that he critiques and some the view that he champions. This is used to illustrate two very broad 'epistemologies.' (In this light, the book champions a very general meta-theoretical stance, not a specific theory.) I suggest that this approach does not offer an argument, i.e., independent rational support, for Vásquez' view. However, it does tell a story that could be very persuasive in the study of religion, given that the use of theory in the discipline tends to be a matter of applying precedents and concepts from an accepted body of literature.     

Sailing between Scylla and Charybdis1: Incorporating qualitative approaches into child psychotherapy research

Starting from the acknowledged gap between research and practice in child psychotherapy, this paper offers an historical perspective on the relation between these two activities, and suggests that qualitative approaches to research may offer new ways of bringing them together. After introducing the fundamental concepts of qualitative analysis, three areas where qualitative forms of research may be useful to child psychotherapists are explored: relevant but non-psychotherapy research; accounts of therapy research; and therapy process research. Examples of all of these types of research are presented, and some of the challenges to incorporating qualitative approaches into child psychotherapy research are discussed.     

Auditory Model Enhances Relative-Timing Learning

In recent experiments (Q. Lai, C. H. Shea, & M. Little, 2000; C. H. Shea, G. Wulf, J. Park, & B. Gaunt, 2001), auditory models were found to be effective in enhancing relative-timing performance and learning in constant practice conditions. In the present experiment, the authors examined (a) whether an auditory model also enhances relative-timing learning in blocked and random practice conditions and (b) whether experience with the auditory model enhances participants' ability to produce the response by using different effector sequences. Participants (N = 48) were randomly assigned to 1 of 4 acquisition conditions in which an auditory model was or was not present and the practice schedule was blocked or random. In the acquisition phase, all participants alternately pressed 2 keys on a keyboard in an attempt to match 5 goal intervals. In the auditory model conditions, a sequence of tones was played before each acquisition trial. The tones represented the correct timing sequence for that trial. One retention and 3 effector-transfer tests without feedback were administered about 24 hr after the completion of acquisition. The results indicated that the auditory model enhanced relative-timing performance and learning independently of practice schedule. In addition, the auditory model enhanced relative timing on the effector-transfer tests, but absolute-timing performance and learning were not affected by the auditory model. Thus, relative timing was found to be effector independent but absolute timing was not.     

A Practice-Specificity-Based Model of Arousal for Achieving Peak Performance

The authors propose a practice-specificity-based model of arousal for achieving peak performance. The study included 37 healthy male physical education students whom they randomly assigned to a high-arousal (n = 19) or low-arousal group (n = 18). To manipulate participants' level of arousal, the authors used motivational techniques. They used heart rate and the Sport Competition Anxiety Test (R. Martens, 1977) to measure the level of arousal that participants achieved. At the determined and given arousal state, the 2 groups performed the task (basketball free throws) for 18 sessions. Both groups performed a retention test at the 2 arousal levels immediately after the last exercise session, in the posttest, and after 10 days. Results showed that both groups learned the task similarly and achieved their peak performance at their experienced arousal level. When tested at an arousal level that differed from the one that they experienced throughout practice sessions, participants' performance had deteriorated significantly. Performance of the task seemed to have integrated with the arousal level of the participants during the task learning. The findings of this study suggest a practice-specificity-based explanation for achieving peak performance.     

Motor Learning through Induced Variability at the Task Goal and Execution Redundancy Levels

The authors examined the influence of introducing variability at two different levels in the learning of a striking task. Variability at the task goal level was introduced by changing target location, whereas variability at the execution redundancy level was introduced by using an intermediate target that constrained participants to use different paths from trial to trial to strike the same target. After practice, participants were transferred to 2 test conditions: (a) a fixed-target test, where the position of the target was unchanged; and (b) a variable-target test, where the position of the target was varied from trial to trial. The results from the manipulation at the task goal level were consistent with predictions from the specificity of practice hypothesis. In both the fixed- and variable-target tests, the best performance was achieved by the group that had practiced in the condition matching the test condition. At the execution-redundancy level, practicing multiple solutions to achieve the task goal did not improve performance in either the fixed- or variable-target tests. These results show that introducing variability at the task goal and execution redundancy levels has different effects on learning and generalization and that practice schedules that constrain the participant to use redundant solutions may not facilitate learning.     

The Effect of Interpolated Motor Activities in Short-Term Motor Memory

This experiment examined the effect of an interpolated motor response on short-term retention of a blind positioning movement. The interpolated response was varied in degree of similarity to the response length (± 25, ± 50, and ± 100 mm.), in number of repetitions (0, 1, or 5), and in temporal position (immediate or delayed), with a retention interval of 25 sec. Absolute error was not affected but a systematic change in response bias due to interpolated motor activity was found. When an interpolated response was longer than the response length, the tendency to undershoot decreased. The defay of the interpolated response was relatively more important than the number of repetitions in producing a positive shift in response bias. These results are interpreted as evidence for a form of interference in short-term motor memory.
