Occupational lead exposure also reduces performance on the various Purdue tasks (Stewart et al., 1999). Further, the peg placement portion of the Purdue Pegboard Test may provide information of lateralizing significance in adults (Costa et al., 1983; Gardner & Broman, 1979; Rapin et al., I966; Vaughan & Costa, 1962) as well as children (Braun et al., 2000). Right-hemisphere lesions tend to impair left-hand scores, whereas left-hemisphere lesions result in a right- sided decrement. Ecological/Predictive Validity Adequate fine motor dexterity is critical in the performance of almost all tasks of daily living. Therefore, faster performance on the Purdue Pegboard Test is associated with better social functioning in patients with schizophrenia (Lehouit et al., 2003) and with a good vocational outcome after TBI in children and adults (Asikainen et al., 1999; Nybo & Koslciniem, 1999). Perhaps the Purdue Pegboard Test taps not only motor dexterity but also the cognitive speed needed for good social or occupational functioning.

    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.
