There is evidence that left-handers perform more proficiently on the assembly component (Judge & Stirling, 2003). Ethnicity/Socioeconomic Status Ethnicity and social class had no impact on test performance of children residing in the greater Rio de Ianeiro area (Brito & Santo-Morales, 2002). Primary language spoken (English, Japanese) among Iapanese adults (aged 65 years and older) also had no effect on peg placement scores (McCurry et al., 2001). Normative Data Norms are available for individuals aged 5 to 89 years. Adults Table 14-22 provides normative data for adults, stratified on the basis of age (15-40 years) and gender (Yeudall et al.,1986). Participants were excluded based on evidence from interview of forensic involvement, prenatal or birth complication, psychiatric disorders or substance abuse problems. Hand preference was determined by the hand used to write with. Administration was one trial per subtest.

Model 32020A User’s Manual [email protected] . 9 Table 14-23 shows normative data (DesRosiers et al., 1995) based on a random sample of 360 individuals, stratified for age and gender, drawn from the electoral pool of a city in Quebec. All subjects were aged 60 to 89 years, lucid and independent in activities of daily living; all could see sufficiently well and had no impairment affecting upper limb functioning. Most (92%) were classed as right-handed based on the Edinburgh Handedness Inventory. McCurry et al. (2001) presented data for the Purdue Peg placing trials based on a sample of Japanese American adults, aged 70 years and older, who were enrolled in a prospective study of aging and dementia in King County, Washington. None was classed as demented based on clinical and screening neuropsychological examinations. Hand preference was determined by asking subjects which hand they preferentially used. Accordingly, 94% of the participants were classed as right-handed (S. McCurry, personal communication May 11, 2004). Participants completed two 30-s trials for each hand. The data are provided in Table 14-24 and represent an important source of information for this understudied segment of the U.S. population. Agnew et al. (1988) provide data (see Table 14-25) based on a sample of 212 healthy, well-educated, 40- to 85-year-olds, who were screened for cognitive impairment. Subtest scores consist of the average of three trials per subtest. Differences between dominant and nondominant hands were also calculated. The manual difference was greater for women than for men. There was a trend for this difference to become greater with increasing age, but the effect did not prove statistically significant. Children Gardner and Broman (1979) provide data (see Tables 14-26 and 14-27) for children, ages 5 years to 15 years 11 months. One trial was given per subtest. The 1334 school children (663 boys, 671 girls) were all in regular classes in a New Jersey suburb. They were primarily in the 95 to 110 IQ range and scored mainly in the middle range on national achievement tests.

    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.
