Brief 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.

Outcome Measures
Primary Outcomes (4)
Labeling - Acquisition Effectiveness
Count of participants for whom the intervention is successful based on percent accuracy labeling target words expressively (number of target words correctly labeled when shown the object divided by the number of words in the set \[i.e., 4\] times 100). The count of participants indicates the number of participants who exhibited a functional relation indicating greater performance for at least one active intervention condition versus the control condition within the comparison phase.
End of intervention. The intervention ends when the participant achieves >75% accuracy 3 sessions in a row (up to 6 months).
Labeling - Acquisition Efficiency
Count of participants for whom the intervention is successful based on percent accuracy labeling target words expressively (number of target words correctly labeled when shown the object divided by the number of words in the set \[i.e., 4\] times 100). The count of participants indicates the number of participants who exhibited a functional relation indicating greater performance for the condition hypothesized to be superior (i.e., "feedback" or "spaced") within the comparison phase.
End of intervention. The intervention ends when the participant achieves >75% accuracy 3 sessions in a row (up to 6 months).
Labeling - Retention Effectiveness
Count of participants for whom the intervention is successful based on percent accuracy labeling target words expressively (number of target words correctly labeled when shown the object divided by the number of words in the set \[i.e., 4\] times 100). The count of participants indicates the number of participants who exhibited a functional relation indicating greater performance for at least one active intervention condition versus the control condition within the maintenance phase.
Four weeks after the intervention ends

Interventions
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.
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.
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.
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.
