Summary

Accommodation

This experiment employed two different testing conditions (the standardized condition and a motivation/attention condition). In both conditions the examiners verbally encouraged the children and provided verbal and edible rewards contingent upon appropriate test-taking behavior.

Participants

Participants in this study included six pre- and elementary school-aged children, five boys and one girl. All were diagnosed with autism. The children's ages ranged from 3 years and 1 month to 9 years and 6 months.

Dependent Variable

Four standardized language and intelligence tests were given: Assessment of Children's Language Comprehension (ACLC; Foster, Giddan, & Stark, 1973) Multiple Components Test Section;ACLC Vocabulary Test Section; Peabody Picture Vocabulary Test-Revised (PPVT-R; Dunn & Dunn, 1981); Intelligence Tests.

Findings

With only one exception, the test scores for the 44 separate testing sessions were always higher in the motivation/attention condition. The higher test scores under the motivation/attention condition were evident for receptive vocabulary tests, receptive language tests, verbal intelligence tests, and nonverbal intelligence tests. Three children, unable to reach a measurable standard score under the standardized test condition, were sometimes able to score in the normal range when the motivation/attention techniques were implemented.
