Model 32020A User’s Manual [email protected] . 23 Comment The task is brief and easy to administer. Users should note that administration rules vary among studies with respect to the number of trials (one, two, or three). The most reliable scores result from averaging subtest scores for the three-trial administration of the test. However, norms for such a version are not currently available for all segments of the population. At a minimum, hand preference, age and gender need to be considered when evaluating test scores. Although normative reports provided here do present data stratified by age and gender, hand preference, and the method of determining handedness, is frequently not reported. As noted earlier, reliability is better when three trials are given per subtest. Accordingly, clinicians who administer the one-trial test should exercise caution when interpreting changes in scores (Buddenberg & Davis, 2000). Further, right-left differences (or ratios) on the Purdue Pegboard Test are not very reliable. Therefore, asymmetries may have diagnostic value only if differences are also found on other tests (Reddon et al., 1988). In this context it is important to bear in mind that measures of lateral preference are imperfect indicators of performance asymmetry. The Purdue Pegboard Test has proved useful in the assessment of motor deficits in both adults and children. It is perhaps not only because the task taps motor ability but also because it is demanding of cognitive speed and attentional control that it makes a useful predictor of functioning in daily life.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
