Increasing Word Learning Efficiency in Children Who Are Deaf and Hard of Hearing Through Retrieval Practice

Vanderbilt University Medical Center·interventional·Posted Aug 23, 2022·Updated Mar 16, 2026

In Brief

A clinical study evaluating Feedback with massed trials, Feedback with spaced trials, and 2 other interventions for Hearing Loss and Language Impairment. Completed, enrolled 13 participants across 1 site.

Detailed Summary

This study is designed to advance the promising yet underutilized research on retrieval practice by evaluating the effectiveness and efficiency of two key retrieval practice features (feedback and spacing). The study uses four single case adapted alternating treatments studies, each with 5- to 9-year-old children who are deaf and hard of hearing to evaluate the effects of feedback and spacing on the efficiency of word learning and retention.

Interventions

Feedback with massed trialsbehavioral

The participant receives feedback on their accuracy completing retrieval practice tasks. For massed trials, exposures for one word are provided before moving to the next word in each session.

Feedback with spaced trialsbehavioral

The participant receives feedback on their accuracy completing retrieval practice tasks. For spaced trials, exposures for each word are interspersed with one another (e.g., an exposure for word 1, then one for word 3, then one for word 2, etc.) in each session.

No feedback with massed trialsbehavioral

The participant does not receive feedback on their accuracy completing retrieval practice tasks. For massed trials, exposures for one word are provided before moving to the next word in each session.

No feedback with spaced trialsbehavioral

The participant does not receive feedback on their accuracy completing retrieval practice tasks. For spaced trials, exposures for each word are interspersed with one another (e.g., an exposure for word 1, then one for word 3, then one for word 2, etc.) in each session.
