(PTI-2) Pictorial Test of Intelligence - Second Edition
Ages: 3 through 8.11 years
Administration: Individual; 15 - 30 minutes
The PTl-2 is an objectively scored, test of general intelligence for both normal and disabled children. Its unique application is for children with physical disabilities who cannot produce responses required by most conventional tests of intelligence (e.g., speaking, writing, manipulation of objects, and pointing). The PTl-2 will be especially helpful when used with children who have difficulty with fine motor skills or a speech-language problem.
PTl-2 Subtests:
• Verbal Abstractions: requires the examinee to identify pictures that (a) represent the meaning of a spoken word, (b) represent the meaning of a spoken definition of a word, and (c) that are different in form or function from a set of pictures.
• Form Discrimination: requires the examinee to match forms, differentiate between similar shapes, identify unfinished pictures, find embedded shapes, and reason about abstract shapes and patterns.
• Quantitative Concepts: samples an examinee's recognition of size, comprehension of number symbols, ability to count, and ability to solve simple arithmetic problems.
Technical Information:
Standardized on 972 persons from 17 states, the PTl-2 provides three types of scores: percentiles, standard scores, and age equivalents. Reliability was demonstrated using coefficient alpha, test-retest, and interscorer procedures. Coefficient alphas for Verbal Abstractions, Form Discrimination, Quantitative Concepts, and Pictorial Intelligence Quotient are .89, .88, .88,
and .94, respectively. Evidence of validity of the PTl-2 test scores is proven for content-description validity, criterion-prediction validity, and construct-identification validity. Finally, the PTl2 items were developed to obtain fairness with diverse groups. The items were examined to ensure that little or no bias relative to gender, race, or ethnicity existed.
The PTI-2 Complete Kit includes:
• Examiner's Manual
• Picture Book
• Profile/Examiner Record Booklets (25)
