Demonstrate task switching and memory strategies

Perform a simulated task-switching and memory exercise: Given a stream of alternating stimuli (digits and colored shapes), respond with digit parity for digits and shape color for shapes as rapidly and accurately as possible; afterward, explain the concrete strategies you used to minimize switch costs, manage working-memory interference, and recover from errors, and propose a two-week practice plan (drills, rest intervals, and metrics) to improve reaction time and accuracy.
