Normative data (U.S.) is available for adults aged 18 ¨C 80 (Bouska & Kwatney 1982), normative for older adults (aged 50+) has been proposed.

Adult norms can be found in:

Bouska, M. and E. Kwatny (1982). "Manual for the application of the motor-free visual perception test to the adult population." Philadelphia, PA: Temple University Rehabilitation Research and Training Center.

MVPT-R Children: (Colarusso & Hammill, 1972; reported in Brown et al, 2003; n = 167 children of various ages)

• Excellent test-retest reliability, 20 days between assessments  (r = 0.77 to 0.83)

MVPT-3 Adults and Adolescence: (Colarusso & Hammill, 2003; n = 28 participants aged 11 to 84 years)

• Excellent test-test reliability, 34 days between assessments (r = 0.92)

MVPT-R Children: (Colarusso & Hammill, 1996; sample = children of various ages)

• Excellent internal consistency (r = 0.81 to r = 0.84)

Acute Stroke: (Cate & Richards, 2000; n = 30 CVA & 20 non-CVA participants; mean age = 58.7 (13.43) years; mean time since stroke onset = 4.25 (3.49) weeks)

• Excellent concurrent validity: Visual screening scores (acuity, visual field deficits, oculomotor skills and visual attention/scanning) and MVPT scores (r = 0.75)

No significant difference between patients with right hemisphere versus left hemisphere lesions. However, patients with right hemisphere lesions generally demonstrated poorer performance on the (original) MVPT (York & Cermak, 1995)

MVPT-R: (Brown et al, 2003; mixed sample)

Development based on five visual categories proposed by Chaifant & Scheffelin (1969) as well as an item analysis.
