A multi-session control computer training condition that is designed to not engage working memory among at-risk adolescents in a traditionally underserved area.

The Digit Span Task is a measure of memory. Participants are presented with digit sequences of increasing length and are required to recall them either in forward order (Digit Span Forward) or in reverse order (Digit Span Backward). Digit Span Forward is a measure of immediate memory and Digit Span Backward is a measure of working memory. Participants will move up or down levels based on correct or incorrect recall of sequences, respectively. Moving up a level will increase the sequence length while moving down a level will decrease the sequence length. Standardized scores range from 0 to 20. Higher scores in this task indicate better performance over 14 trials. Computerized memory tasks such as this have demonstrated increased reliability in short-term memory assessments.

The Stop Signal Task (SST) is a measure of response inhibition. Participants are first presented with either a left pointing arrow or a right pointing arrow. They are required to select the left arrow button upon seeing a left pointing arrow and the right arrow button upon seeing the right pointing arrow. After 16 trials, a second component is added to the task. Participants will continue to select left or right arrow buttons, but once they are presented with an auditory cue (a beep), they need to withhold their response. The delay in presenting the auditory cue after the arrow is shown (Stop Signal Delay; SSD) will become longer or smaller based on participant performance. The stop signal response time (SSRT) gives an estimate of the time it takes for a response to be stopped upon hearing the cue. Longer SSRT generally indicates poor performance on the SST. Standardized scores range from 0 to 100 with greater scores representing better task performance.

Letter Number Sequencing (LNS) is a measure of working memory. This test has two parts to it: the forward test and the reordered test. In the forward test, the participant is visually presented with a list of scrambled letters and numbers that they must type into a text box in the same alphabetical and numeric order that was presented. In the reordered test, the participant is visually presented with a list of scrambled letters and numbers that they must type into a text box with numbers listed first in ascending order and letters listed second in alphabetical order. The length of the target string increases over time until the participant is no longer able to correctly sequence three letter/ number stems in a row. The investigators will use a computerized version of the LNS test. Higher scores in this test indicate better outcomes with standardized scores ranging from 0 to 20.

The Alcohol Expectancy Questionnaire-Brief (AEQ-B) is a self-report questionnaire that tap youths' perception of positive and negative outcomes related to using alcohol. Because this intervention is designed to orient youth towards longer-term (rather than immediate) rewards, the investigators expect to see significant decreases in positive expectancies of alcohol use and an increase in negative expectations. The AEQ has been found to be reliable and valid indicators of adolescents' perceptions of use. Seven items on the questionnaire are rated on a 1 to 5 scale, with higher scores generally indicating worse outcomes. Scores range from 7 to 35.

The Marijuana Effect Expectancy Questionnaire-Brief (MEEQ-B) is a self-report questionnaire that tap youths' perception of positive and negative outcomes related to using marijuana. Because this intervention is designed to orient youth towards longer-term (rather than immediate) rewards, the investigators expect to see significant decreases in positive expectancies of marijuana use and an increase in negative expectations. The MEEQ has been found to be reliable and valid indicators of adolescents' perceptions of use. Six items on the questionnaire are rated on a 1 to 5 scale, with higher scores generally indicating worse outcomes. Scores range from 6 to 30.

The Youth Risk Behavior Survey (YRBS) is a self-report measure of the prevalence of real world risk behaviors, including compromised safety behaviors (e.g. not wearing a seat belt), substance use, risky sexual practices, and delinquent behaviors (e.g. gambling, theft). Because substance use has been associated with problematic behaviors more broadly, the YRBS will allow us to tap engagement in a variety of related risky behaviors. Consistent with previous research, the investigators will create an aggregate of substance use and risk behaviors as an index of risky behaviors. Composite scores such as these have demonstrated adequate psychometric properties. There are 71 items on the scale that will be analyzed at the item level. Most items on the survey are reported on a 0 to 5 scale, with the score of 5 indicating riskier behavior.

The Balloon Analogue Risk Test - Youth (BART-Y) is a measure of risk aversion. It requires participants to choose between continuing to pump a balloon or collecting the winnings they already earned from pumping the balloon before. Participants will earn money for every successful pump where the balloon remains unexploded. If the balloon explodes before they collect their winnings, they will lose all the money they could have collected from the given balloon. Participants are given 30 balloons in this task. The average number of pumps for the unexploded balloons is calculated at the end, where a higher number of average pumps indicates worse outcomes (greater risk seeking behavior and lower risk aversion). Scores range from 0 to the maximum number of pumps before the balloon explodes which varies across the task.
