Irregular Past Tense Verbs

These two forms provide stimuli for producing irregular past tense verbs and can be used in therapy or sent home with a student for additional practice at home. The age of mastery (80%) is based on an article by Shipley et. al (1991) from Language, Speech & Hearing Services in the Schools.

The verbs "bent, chose, fought, held, sang, sank, stood, swang" and "swept" did not reqach criterion by age 8 years, 5 months through 8 years, 11 months in the Shipley study.
Children's Development of Irregular Past Tense Verb Forms

Abstract: In Brown's (1973) classic studies of language development,he found that irregular past tense verbs developed rather earlyin the developmental sequence. Several other researchers havealso noted this early development of irregular verb forms. However,other researchers and clinicians have suggested that irregularverbs continue developing much later into the school-age years.The purpose of this study was to gain a preliminary view of children's development of 49 irregular verbs. One hundred andtwenty children between 3:0 and 9:0 were examined as they respondedto a picture of the target verb with a sentence-completion task.It was found that some irregular verbs (e.g., hit) were correctlyproduced by the three year olds, but other irregulars (e.g.,bent) were still not mastered by age 9. A preliminary orderof development of the irregular verbs and possible clinicalimplications are offered.


The article cited below has an Appendix with a set of 36 sentences that I use in a sentence imitation task to track progress in the Percent Consonants Correct (PCC) in a student's speech. I use the following scale for determining severity of speech delay or reduction in intelligibility using this sentence imitation task.
>90% correct = mild
65 - 85% correct = mild - moderate
50 - 64% correct = modereate - severe
<50% = severe
An objective and time-efficient method for determining severity of childhood speech delay.

Abstract: To address the need for an efficient and valid approach to determining the severity of a child's speech delay, this study compared 2 types of sampling procedures to derive a measure of percentage of consonants correct (PCC; L. D. Shriberg and J. Kwiatkowski, 1982). PCC scores of twenty-one 4- to 6-year-old children with speech delay derived from both an imitative sentence task and a conversational task were compared. Scores did not differ significantly and corresponded favorably with a reference criterion (S. M. Benner, 1992) for determining clinical equivalence. The imitative approach required considerably less time to complete. Thus, the sentence imitation procedure offers a valid and efficient alternative to conversational sampling. However, clinicians should consider individual child characteristics when choosing an imitative approach.
