This study examined the effects of performance feedback information on parenting practices that contribute to development of vocabulary and pre-literacy skills. Fifty-one dyads of parents and their pre-school aged children were randomly assigned to one of three treatment groups. Group one received full treatment including a workshop and feedback. Group two, designated as the control group, did not receive the feedback portion of the treatment; and group three, designated as a wait list control group, received neither the workshop nor performance feedback. All participating parents were administered a survey of parenting practices that lead to vocabulary and pre-literacy development. Treatment produced significant results for the vocabulary measure; however, the data did not yield a significant result for the cognitive measure. There appeared to be a significant difference between the treatment group and the wait list control group. This difference was not found when comparing the treatment group to the control group, or when comparing the control to the wait list control. Also, feedback was shown to have an effect on only one of the five parenting practices surveyed.
