Interventions

  • Accuracy-maximized condition — BEHAVIORAL
    Naming treatment condition in which the target will be immediately provided for repetition at picture onset.
  • Effort-maximized condition — BEHAVIORAL
    Naming treatment condition in which participants will have up to 10 seconds to respond before the target is provided for repetition.
  • Effort-accuracy balanced condition — BEHAVIORAL
    Naming treatment condition in which naming deadlines will be determined based on the balanced effort-to-accuracy benefit ratio formalized above, calculated on clinician-provided accuracy and response time ratings. Deadlines will be recalculated session-by-session to adjust to participant-specific treatment gains over time.

Study Details

Aphasia is a language disorder caused by stroke and other acquired brain injuries that affects over two million people in the United States and which interferes with life participation and quality of life. Anomia (i.e., word- finding difficulty) is a primary frustration for people with aphasia. Picture-based naming treatments for anomia are widely used in aphasia rehabilitation, but current treatment approaches do not address the long-term retention of naming abilities and do not focus on using these naming abilities in daily life. The current research aims to evaluate novel anomia treatment approaches to improve long-term retention and generalization to everyday life. This study is one of two that are part of a larger grant. This record is for sub-study 1, which will adaptively balance effort and accuracy using speeded naming deadlines.

Arms

  • Experimental: Effort-maximized, then accuracy-maximized, then effort-accuracy balanced
    All participants will receive all three naming treatment conditions in a randomized order - this is one possible ordering of those conditions.
