Protocol - Grammatical Impairments - Test of Early Grammatical Impairment

Add to My Toolkit
Description:

Past Tense Probe and Third Person Singular Probe are interviewer-administered subtests of the Rice/Wexler Test of Early Grammatical Impairment (TEGI). The interviewer uses a picture elicitation task to elicit target forms of grammar. Normative data are available to assist in scoring results.

Summary of Rice/Wexler Test of Early Grammatical Impairment (TEGI)

The Past Tense Probe and Third Person Singular Probe subtests of the Rice/Wexler Test of Early Grammatical Impairment (TEGI) assess children's grammar in the domain of tense-marking, a widely studied clinical marker of language impairments in children that has been used as a behavioral phenotype in genetic studies of specific language impairment (SLI). Both subtests use a conventional picture elicitation method. The Past Tense Probe consists of a total of 20 items; the Third Person Singular Probe consists of a total of 11 items. Total time of administration for both subtests is 10 to 15 minutes for typically developing children.

Scoring Instructions

Children's responses are recorded on a response form and scored in reference to norms for children ages 3 to 9 years. The reference samples consist of 50 children per 6-month age level ascertained in a population-representative manner. Separate reference samples are provided, per age level, for typically developing children and children with language impairments. Available scores include means and standard deviations per reference sample per age level; sensitivity and specificity scores; and a criterion score defined by optimal sensitivity and specificity levels.

Participants:

Children, ages 3 - 8 years

Specific Instructions:
The Rice/Wexler Test of Early Grammatical Impairment is a proprietary instrument. Each Rice/Wexler Test of Early Grammatical Impairment (TEGI) subtest is a part of a complete assessment and is not sold separately. To administer/use a subtest requires a licensing agreement from Pearson. Researchers should complete and return an application to pas.licensing@pearson.com. In order for this assessment to be considered valid, the investigator should make sure that the respondent speaks English as a first language. For genetics studies children should be assessed for hearing or nonverbal cognitive impairment as related factors.
Selection Rationale

The Rice/Wexler Test of Early Grammatical Impairment (TEGI) was selected because it is a validated protocol and is the only known assessment tool that tests for the presence of this particular set of grammar forms that are diagnostic of language impairment in this age range.

Definition

This measure is a test that assesses the respondent's knowledge of grammar.

Purpose

This measure can be used to identify respondents with specific language impairment or other categories of language impairment. Language impairment refers to problems acquiring and using language, including the inability to use correct verb forms. Language impairment can appear with or without related impairments of hearing and/or nonverbal cognition.
