Older adults (60+ years of age) who meet criteria for mild cognitive impairment and insomnia will be randomly assigned to cognitive training or trivia training and will complete measures of anxiety, sleep, cognition (objective, self-efficacy), and arousal at baseline, and post-intervention. For cognitive training, participants will be provided with login information to access the computerized training, and will complete 8 weeks (45 mins 3x/week) of cognitive training. For trivia training, participants will receive weekly emails that contain trivia assignments that they will complete for 8 weeks (45 mins 3x/week). We will evaluate short-term (i.e., post-training) effects of the two training conditions on subjective anxiety, sleep, arousal, and subjective and objective cognition.

The computerized training exercises and brain games help stimulate cognitive functions while providing real-time monitoring on the evolution of participants' skills.
The computerized trivia training asks participants to answer general questions related to pop culture, science, geography, etc. Participants can use online sources to search for answers and will be provided feedback on their accuracy.

Time frame: Up to 10 weeks
Objective Sleep-Watchpat
Single night objective sleep recording via a wrist worn device.
Time frame: Up to 10 weeks
Physiological Arousal- Heart Rate Variability
CorSense monitor assessed 5 min heart rate recordings both at rest. Time index variables: SDNN (standard deviation of normal to normal heartbeat intervals)
Time frame: Impact of game related experience will be measured at baseline
Anxiety - State-Trait Anxiety Inventory
Inventory that asks respondents to rate how true 20 self-descriptive statements (e.g., I feel calm) are on a 4-point scale (1 = not at all, 4 = very much so). Typically, respondents are asked to rate statements according to how they generally feel (trait-anxiety scale) and how they feel in the current moment (state-anxiety scale). Total scores range from 20 to 80, with higher scores indicating greater maladjustment.
Time frame: Up to 10 weeks
Game-related experience- Sessions and duration played
During the intervention phase the cognitive training group will play games and will need to log the days and duration played.
Time frame: Up to 10 weeks
Circadian Rhythm- Morningness-Eveningness Questionnaire
19-item questionnaire that assesses preference for morning, afternoon, and evening activities. Total score reflects degree of "morningness" or "eveningness" type.
Time frame: Up to 10 weeks
Perceived Stress- Perceived Stress Scale Subjective Arousal- Perceived Stress Scale
Perceived Stress Scale is a self-report measure of how life situations are perceived as stressful. The scale consists of 15 items corresponding to everyday situation and participants are asked to rate on a scale from 0 (never) to 4 (very often) how often they felt or thought a specific way. Higher scores correspond to higher perceived stress.
Time frame: Up to 10 weeks
Subjective Arousal- Arousal Predisposition Scale
Arousal Predisposition Scale is a 12-item inventory that has been designed to measure the degree to which an individual experiences arousal. Higher scores indicate greater predisposition to arousal.
Time frame: Up to 10 weeks
Game Engagement Questionnaire
Questionnaire assessing the experience of the game.
Time frame: Up to 10 weeks
