Differentiating visual and kinesthetic imagery in mental practice.

Through two experiments, the study sought to emphasize the usefulness of the visual and kinesthetic imagery in mental practice. In Experiment 1, it was hypothesized that when the task to be learned through mental practice necessitates the reproduction of a form by drawing, the visual image, which provides a wide span of apprehension, is more suitable than the kinesthetic image. On the other hand, the kinesthetic image that supplies inputs from the muscles' positions and movements should be more appropriate for the acquisition of the duration of the drawing. In Experiment 2, it was hypothesized that the task, transformed into a motor task necessitating minute coordination of the two hands, would benefit more from kinesthetic imagery. To have optimal control over what was actually experienced during mental practice, the participants' imagery skills were measured. The participants also benefited from prior imagery training. The results demonstrate that when using mental practice to initially acquire a task, visual imagery is better for tasks that emphasize form while kinesthetic imagery is better for those tasks that emphasize timing or minute coordination of the two hands.

The importance of professional psychology: A view from managed care.

Over the past 15 years, the development of managed health care has led to changes in the way that psychology is practiced and in the ways that quality is measured in the health care system. In this article, the current status of population-based Health Plan Employer Data and Information Set quality metrics are reviewed. Many medical measures of quality have improved in the past 5 years, whereas behavioral health measures have shown only modest improvement. Reasons for this finding are discussed, and it is suggested that quality of care for individuals and populations could improve as psychology adopts evidenced-based practice and clinical practice guidelines.

Determination and Documentation of the Need for Practice Guidelines.

In August 2001, the American Psychological Association (APA) Council of Representatives approved as APA policy the "Criteria for Practice Guideline Development and Evaluation" (APA, 2002b), developed by the Board of Professional Affairs Committee on Professional Practice and Standards (COPPS). The present document was developed in response to a request from the APA Board of Directors that the Board of Professional Affairs develop a document expanding on Section 2.2 of the guideline development and evaluation criteria, which indicates that practice guidelines should be written only when there is a clearly demonstrated and documented need. The Board of Professional Affairs further requested that COPPS consider the specific legal, public, and professional needs that may justify the development of guidelines and the related sources of documentation. Developers of practice guidelines should review the guideline criteria carefully at the beginning of the project and frequently thereafter to help ensure consistency of the guidelines with APA policy. Note that this document is not intended to be a stand-alone document but rather is to be understood and used in the context of the criteria. The intent of this document is to provide developers of guidelines with additional information related to the demonstration and documentation of the need for practice guidelines in their areas of interest.

Comparability, Reliability, and Practice Effects on Alternate Forms of the Digit Symbol Substitution and Symbol Digit Modalities Tests.

The present study examined the comparability of 4 alternate forms of the Digit Symbol Substitution test and the Symbol Digit Modalities (written) test, including the original versions. Male contact-sport athletes (N=112) were assessed on 1 of the 4 forms of each test. Reasonable alternate form comparability was demonstrated through establishing normality of form distributions and conducting pairwise form comparisons of means, variability, and intraclass correlations. Nonetheless, alternate forms are likely an insufficient means of controlling practice in speeded measures at brief (1-2 weeks) retest intervals. Reliable change indices demonstrated that practice must be accounted for in individual retesting. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Especial Skills: Their Emergence With Massive Amounts of Practice.

Differing viewpoints concerning the specificity and generality of motor skill representations in memory were compared by contrasting versions of a skill having either extensive or minimal specific practice. In Experiments 1 and 2, skilled basketball players more accurately performed set shots at the foul line than would be predicted on the basis of the performance at the nearby locations, suggesting considerable specificity at this distance. This effect was replicated even when the lines on the court were obscured (in Experiment 2). However, the effect was absent when jump shots were executed in Experiment 3. The authors argue that massive levels of practice at 1 particular member of a class of actions produce specific effects that allow this skill to stand out from the other members of the class, giving it the status of an especial skill. Various theoretical views are proposed to account for the development of these skills. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
