Validity data

Judgment of the Line Orientation Test (JLO; Benton, Sivan, & Hamsher, 1994 )

Measure of spatial perception and orientation. Items are presented in an ascending order of difficulty. Test material are presented in spiral-bound booklet, with 35 stimuli individually presented in the upper page and 11 line choices in an array are presented in the lower part. Subject required to identify the two lines from the array that match the direction of the stimulus lines.

Internal reliability coefficients were .84 to .91 in adults (Benton et al., 1994) . Test retest reliability coefficient of .90 (Benton et al., 1994) ^a,c

Convergent validity with loading of the JLO on the Performance subtests of the WAIS. The test measures abilities separate from facial recognition (Larrabee, 2000) ^a,c

Hooper Visual Organization Test (HVOT; Hooper, 1983 )

Consists of 30 drawings of common objects on 4x4 inch cards in a ring binder. Each object is cut into 2 or more parts and randomly arranged. The task is to visually integrate the parts and name the object.

Internal reliability coefficients were >.80 in adults (Lopez, Lazar, & Oh, 2003) . Test retest reliability coefficient of .86 (Lezak et al., 2004) ^a,c

Convergent validity with loading of the HVOT on visual-spatial intelligence factor and had its highest correlation with the Performance IQ (Johnstone & Wilhelm, 1997) ^a,c

Rey-Osterrieth Complex Figure Test (Developed by Rey (1941) and translated by into English by Corwin and Bylsma, 1993 )
