Stroop test. The Stroop test is a measure of executive functions, specifically the ability to inhibit a habitual response, selective attention, and shifting (Pachana et al., 2014). This test requires participants to identify the color name printed in the same ink color (e.g., BLUE printed in blue ink; congruent condition) or different ink color (e.g., BLUE printed in red ink; incongruent condition). Each stimulus word (i.e., red, green, and blue) was presented in equal proportions to minimize specific word facilitation. After nine practice trials, 72 stimuli (i.e., 2 blocks of 36) were presented to the participants using the Eprime software (Version 3.0). Participants were asked to press the key with the dot sticker corresponding to the three stimuli colors (i.e., red, blue, or green). Reaction time (RT) and accuracy were used as indices of performance.

Berg Balance Scale (BBS). The BBS was developed to measure balance and fall risk among older adults. This scale is comprised of 14 tasks to assess balance, such as standing with eyes closed and retrieving an object from the floor. Performance is rated on a 0 to 4 scale for each task, with "0" indicating the lowest level of function and "4" the highest level of function. Total scores of 41 to 56 indicate a low fall risk, 21 to 40 a medium fall risk, and 0 to 20 a high fall risk (Berg et al., 1992).

Medication task. A medication task was developed to test the participants' ability to properly complete their pill organizers. Participants read a fictional story about prescribed medications and were asked to determine the required frequency and dosage of the medications based on the prescription and the label on fake medication bottles filled with candy pills. Participants had to place the medications in a weekly pill organizer for each required day and time slot (AM and PM). Two scenarios were designed to both require a similar number of pills to be placed in the weekly container for pre and post-test. Time to complete the task and number of mistakes for each day and time slot were recorded as indices of performance. Mistakes were recorded when participants added too many or too little pills, when pills were placed in the incorrect AM/PM time slot, or when participants added the wrong type of medication on a given day.
