Practice effects on digital cognitive assessment tools: insights from the defense automated neurobehavioral assessment battery
We systematically evaluated practice effects using the DANA battery as a case study. Modest practice effects were observed across two testing sessions, with a median inter-session interval of 93 days. Cognitive impairment was significantly associated with slower response times in key tasks (p < 0.001). Our framework offers a systematic approach for evaluating practice effects in digital cognitive tools.
