12 weeks of at-home EF training on a computer or iPad
Behavioral: Executive function (EF) training
This will be a comparator arm with no cognitive training. Participants will be given access to the same training program following the conclusion of the study, but no further assessment is planned.
EF training will involve at-home computer- or tablet based training to improve several EF processes, including divided attention, response inhibition, switching, and working memory updating. Training session duration = 30 min x 3 session/week.
Pre-training Change in auditory 2-back accuracy
Auditory 2-back performance will be assessed under single- and dual-task conditions (i.e., while the participant is standing or simultaneously walking on a treadmill at a self-selected pace). The numbers for the task will be played through binaural speakers, and the decibel level will be individualized for each participant depending on hearing ability. Participants will be required to make a button response indicating whether the number they heard was the same or different from the number they heard two previously. Accuracy (percent correct) will be recorded. Half the participants will be given this assessment. See Outcome 5, Multi-talker, for other half.
Time frame: baseline
Post-training Change in auditory 2-back accuracy
Auditory 2-back performance will be assessed under single- and dual-task conditions (i.e., while the participant is standing or simultaneously walking on a treadmill at a self-selected pace).

Participants will be required to make a button response indicating whether the number they heard was the same or different from the number they heard two previously.

Pre-training Multi-Talker word perception (accuracy)
We will use the multi-talker spatial listening task for the other half of the participants, in which a presented text cue indicates which of three simultaneously presented, but spatially distributed spoken sentences to report. Traffic noise will be included to more closely simulate real- world conditions. The signal-to-noise ratio will be held constant across participants, with signal intensity set according to individual average hearing thresholds.

Pre-training Change in stride time (mean, standard deviation [SD] of stride time)
Stride time will be assessed under single- and dual-task conditions (i.e., walking on a treadmill at a self-selected pace or while simultaneously completing the auditory 2-back task). The spatio-temporal characteristics of gait will be measured by foot pressure sensors worn on the base of the participants' shoes, with one sensor placed beneath the heel and the second sensor placed beneath the toe. The time between successive toe or heel strikes will be recorded (sec) and averaged across the trials. Those participants being assessed with Outcome 5 will perform the same walking task but in a simulated street-crossing environment.

Pre-training Montreal Cognitive Assessment (MoCA)
Neuropsychological test to evaluate global cognitive status. Scored on 30, a score of 26 or higher is used to identify Mild Cognitive Impairment (MCI) however a score of 23 or higher is used in this study as this cut-off has been shown to lower false positivity. (Nasreddine et al., 2005)

Pre-training Trail Making Test
Neuropsychological test to evaluate processing speed and executive functioning (Reitan, 1992). In form A, participants use a pencil to connect circles on a page in ascending numerical order. In form B, participants connect circles, alternating between ascending number and letter series. Time to complete (s) is recorded per form. Difference between Forms B and A completion times provides an index of switching, updating, and is considered a measure of executive function.

Pre-training Mobility functioning as assessed by the Mini BESTest
The Mini BESTest is comprised of four sub-scales to evaluate balance performance, including an anticipatory sub-scale (e.g., sit-to-stand, toe rise), a reactive postural control subscale (measures compensatory stepping when one's centre of balance is displaced in the forward, backward, or lateral position), a sensory orientation subscale (e.g., eyes closed, foam mat), and a gait subscale (e.g., walking over an obstacle).

Pre-training Functional neuroimaging (fNIRS)
Portable functional near infrared spectroscopy (BRITE MKII) will be used to assess prefrontal cortex activity during the single- and dual-task walking conditions. Sixteen detectors will be placed strategically 2.8 cm away from the optodes, eight of them will be dorsal to the optodes, while the other eight will be ventral, so that each probe has four dorsal detectors and four ventral detectors. The two probes will be placed symmetrically over the lateral prefrontal cortex and the most anterior and most ventral pair of optode-detector of each probe will be placed on Fp1/Fp2. The probes were designed based on existing configurations. Of interest are relative changes in concentration of frontal oxy-hemoglobin (HbO2: measured at absorption peak of 850nm) and deoxy-hemoglobin (HbR: measured at absorption peak of 735nm) compared to the baseline rest data.

Of 25 interventional studies with no phase under Presbycusis, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 58. This study's 35 months is above that.
