Development, Validity, and Reliability of the Reactive Skill Test in Older Adults

The Reactive Skill Test will be conducted using a setup consisting of four pods, white cones, and balls that match the colors of the light signals During the test, a ReactionX device configured with four distinct light colors (red, green, blue, and yellow) will be used. The test protocol is programmed via the ReactionX mobile application to control the sequence and display of lights. Each LED light is illuminated in a randomized order with zero delay time. Upon illumination, the participant is required to select the ball corresponding to the color of the light, place it on the matching cone, and then deactivate the LED light of the same color as the last placed ball. The test concludes once this sequence is completed for all four lights. Performance is evaluated based on parameters such as reaction time, accuracy, and total completion time. This protocol is specifically designed to assess cognitive skills such as color recognition, reaction time, motor coordination, and attention.
