The study will compare the effect of broad and directed (narrow) technology-based training on basic perceptual and cognitive abilities in older adults and on the performance of simulated tasks of daily living including driving and fraud avoidance.
Participants will be randomly assigned to four training conditions: broad training using either 1) Posit Science's web-based "BrainHQ" or 2) the video game Rise of Nations, or to directed training for 3) Instrumental Activities of Daily Living (IADL) training on both driving, American Association of Retired Persons (AARP)'s web-based older driver training program, and training for fraud avoidance, a web-based tutorial on finance and fraud, or 4) to an active control condition of puzzle solving. Training will take approximately 15-20 hr for each treatment condition. Before training begins, participants will take baseline ability tests of perception, attention, memory, and cognition, activities of daily living, as well as a driving simulator test for hazard perception, and a financial fraud recognition test. They will be tested again on these measures following training completion, and at a one-year follow-up from training completion.

| Fraud Detection Post Training | Percent confidence that a given vignette describing fraud is actually an example of fraud, measured at baseline and immediately after 4 weeks of training. Participants were given a vignette describing fraud (which was mixed in with vignettes not describing fraud) and were asked to give their percent confidence that this is actually an example of fraud. Higher confidence indicates higher accuracy when detecting fraud, with a minimum of 0 and a maximum of 100. Measures accuracy in discriminating fraud from non-fraud text-based scenarios (using 3 parallel forms). | Baseline, Immediately after 4-week intervention training |
| Driving Simulator Hazard Perception Post Training | Driving simulator (scenarios including hazards) measures of speed, maximum brake compression, and lane position, at baseline and immediately after 4 weeks of training. These measures provide an estimate of accuracy in driving scenarios that involve hazards in the DriveSafety simulator (using 3 parallel forms). All measures were transformed into Z scores and averaged in order to create a measure of overall driving performance, where higher scores represent more dangerous (worse) driving performance. | Baseline, Immediately after 4-week intervention training |
| Self-reported Difficulty With Instrumental Activities of Daily Living (IADLs) Post Training | Self-reported difficulties in completing instrumental activities of daily living, measured at baseline and immediately after 4 weeks of training, with a minimum score of 0 (indicating no difficulty) and a maximum of 3 (indicating severe difficulty). This is a modified short-form version of the Lawton IADL Items, used in the Multicenter AIDS Cohort Study (MACS). | Baseline, Immediately after 4-week intervention training |
| Speed of Processing Post Training | Scores from Useful Field of View (UFOV) test and Digit Symbol Substitution Test, at baseline and immediately after 4 weeks of training, which each provide a measure of speed of processing. Raw scores were transformed into z scores, UFOV reaction time scores were inverted, then both UFOV and digit symbol scores were averaged in order to create an estimate of overall speed of processing, where higher scores represent better performance. |
| Measure | Description | Time Frame |
|---|---|---|
| Technology Proficiency Post Training | Standardized Z-scores of Computer Proficiency Questionnaire and the Mobile Device Proficiency Questionnaire, at baseline and immediately after 4 weeks of training, which provide measures of technology proficiency. Scores are measured as a self-assessed proficiency, where higher scores indicate a higher proficiency and greater ease using a device on various tasks. Scores are standardized using z-scores, with the average at the baseline representing 0, and 1 representing one standard deviation above the average baseline score. |

8 participants were consented and completed some baseline measures, but removed themselves from the study before they were randomly assigned to a certain condition. Thus, 238 participants agreed to participate in the study, but only 230 participants appear at baseline across conditions.

Speed may indicate risky driving behavior. | Participants were instructed that they could refuse any individual measure, which may influence the participant counts for some measures. This was particularly pronounced for driving simulator measures because of discomfort and simulator sickness. | Posted | Mean | Standard Deviation | Miles Per Hour | Baseline, One-year after 4-week intervention training |

| Primary | Driving Simulator Max Brake Compression at One Year | Maximum brake compression in a driving simulator measured at baseline and one year after 4 weeks of training. Maximum brake compression measures the most that the brake pedal was compressed during driving, with a minimum of 0 and a maximum of 1. Maximum brake compression may indicate urgent stopping. | Participants were instructed that they could refuse any individual measure, which may influence the participant counts for some measures. This was particularly pronounced for driving simulator measures because of discomfort and simulator sickness. | Posted | Mean | Standard Deviation | units on a scale | Baseline, One-year after 4-week intervention training |

|
| Primary | Driving Simulator Average Lane Position at One Year | Average lane position in a driving simulator measured at baseline and one year after 4 weeks of training. Lane position measures the average deviation from the center of a lane while driving (values from -1 to 1), averaged across participants, where 0 represents perfect center, negative scores represent deviation to the left (from 0 to -1), and positive scores represent deviation to the right (from 0 to 1). Lane position indicates vehicle control and safety. | Participants were instructed that they could refuse any individual measure, which may influence the participant counts for some measures. This was particularly pronounced for driving simulator measures because of discomfort and simulator sickness. | Posted | Mean | Standard Deviation | units on a scale | Baseline, One-year after 4-week intervention training |

|
| Primary | Digit Symbol Substitution Test Post Training | The Digit Symbol Substitution Test measured at baseline and immediately after 4 weeks of training. The Digit Symbol Substitution Test is measured through the number of items completed during a 90 second period, where higher scores indicate faster/better performance. | Participants were instructed that they could refuse any individual measure, which may influence the participant counts for some measures. | Posted | Mean | Standard Deviation | items completed | Baseline, Immediately after 4-week intervention training |

| Secondary | Technology Proficiency Post Training | Standardized Z-scores of Computer Proficiency Questionnaire and the Mobile Device Proficiency Questionnaire, at baseline and immediately after 4 weeks of training, which provide measures of technology proficiency. Scores are measured as a self-assessed proficiency, where higher scores indicate a higher proficiency and greater ease using a device on various tasks. Scores are standardized using z-scores, with the average at the baseline representing 0, and 1 representing one standard deviation above the average baseline score. | Participants were instructed that they could refuse any individual measure, which may influence the participant counts for some measures. | Posted | Mean | Standard Deviation | z-score | Baseline, Immediately after 4-week intervention training |
