Individuals with Aphasia
Participants complete all four interventions Retrieval Practice + Moderate Intensity Exercise: Subjects will engage in 30 minutes of moderate-intensity cycling prior to word learning using Retrieval Practice (active retrieval during learning) Retrieval Practice + Gentle Stretching: Subject will engage in 30 minutes of gentle upper- and lower- limb stretching prior to word learning using Retrieval Practice (active retrieval during learning) Study Only + Moderate Intensity Exercise: Subjects will engage in 30 minutes of gentle stretching prior to word learning using Study Only (no active retrieval during learning) Study Only + Gentle Stretching: Subjects will engage in 30 minutes of gentle stretching prior to word learning using Study Only (no active retrieval during learning)
