  • 18 item Risk Taking questionnaire (RT-18)
  • Computerized Columbia Gambling Task (CGT)
  • Balloon Analogue Risk Task (BART)
  • Computerized Clock Task, a real-time reinforcement learning paradigm.
  • Puberty Measures - Petersen and Tanner scales
  • Reynolds Intellectual Screening Test (RIST) will be used to obtain an IQ measure
  • SES/Demographics
  • saliva Saliva samples for future genetics and hormonal analyses
  • Annett Handedness
  • Computerized rewarded Stroop task
  • WAIS Coding digit symbol task – to measure processing speed
  • UPPS-P Impulsivity Scale
  • ASR/YSR Youth Self-Report (YSR_11-18) for participants age 12-17, OR Adult Self-Report for participants age 18-30 (ASR_18-59)
  • CANTAB Eclipse Battery testing [AST, DMS, MOT, SOC, SSP, SST]
  • Antisaccade Tasks task administration
  • Intolerance of uncertainty scale (IUS): Aversion to uncertainty or unknown outcomes will be assessed using the intolerance of uncertainty short form scale, a 12-item questionnaire
    • Adapted by Carleton, R. N., Norton, M. A., & Asmundson, G.J. G. (2007) from the original, longer scale (Freeston, M., Rhéaume, J., Letarte, H., Dugas, M. J., & Ladouceur, R., 1994). IUS scores are strongly related to anxiety and depression, and will be used in comparison to exploitative reward behaviors as assessed in our neuroimaging task. The IUS assesses two sub-scales of uncertainty: prospective (i.e., avoidance) and inhibitory (response to uncertainty).
  • Motor sequence learning task: Subjects will perform a computerized task that has been designed in house to assess behavioral learning across individuals, as well individual differences in learning strategies that may be related to exploratory behaviors being assessed in the neuroimaging task. Subjects will learn a pair of 4-button press motor sequences at a time, each associated with a different image (e.g., tools, animals). In separate blocks, subjects will learn sequences in a fixed pattern (A-A-A-A-B-B-B-B), a randomized pattern (e.g., A-B-B-A-A-B-A-B), or will be able to choose on each trials which pattern (A or B) to practice. Learning performance compared across blocks will indicate the extent to which selecting which sequence to practice (“agency”) contributes to learning.
  • NEO-FFI: The FFI questionnaire is comprised of 60 items designed to assess five domains of personality traits, based on Costa and McCrae (1978). Personality domains include Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Previous research suggests significant associations between adolescent risk-taking and five-factor personality constructs (Gullone & Moore, 2000).
  • QHOQOL-BREF assessment tool
