The dual-task will comprise of a simultaneous auditory digit span [DS] and a visual response time [RT] test. Participants will hear a series of five, seven and nine-digit sequences that are presented in a random order, but will remain consistent for each participant. Participants will be asked to verbally repeat back the digits 2-s after the onset of the final digit in the correct order, with a time-limit of 1-s per digit to recall the sequence, and awarded 2 points for every correct digit recalled in the correct place and 1 point for each correct digit in the incorrect location. 1 point is deducted for each digit recalled that was not in the original sequence. The accuracy score is then converted into a percentage. Whilst engaging the auditory task, participants will simultaneously partake in a visual RT test which involves an image of a small football being randomly presented for 200ms on a white background in one of four quadrants of a computer screen. Participants will be required to press an allocated button with their dominant hand in response to the stimuli as quickly as possible. Images will be presented in pseudorandom interludes between the words “ready” and “go” on the DS test, and will appear 750-1,000ms prior to the onset of the next auditory stimulus. During each test, 96 footballs will be presented and reaction time score will be recorded as the average time (ms) taken to respond to the stimuli across these trials. 

Any help would be much appreciated! So far I have four slides with the football image in each quadrant... so I've got a long way to go!
