Table 1. Performance in Adolescents and Adults.

Task performance in adults and adolescents: mean (standard deviation) and variability (standard deviation) of percent risky selections (number of times 10 and 30 options were selected relative to the total number of presentations of the10/90 and 30/70 wheels); mean (standard deviation) reaction time (ms) for the selection of risky options (10 and 30) and for the selection of safe options (70 and 90).

Adults (n=14) Adolescents (n=16)
Percent Risky Selections (10 & 30) % 46 (28) 51 (27)
Variability (SD) in risky vs. safe selections % 40 (17) 38 (16)
Reaction time for risky selections (10 & 30) ms 1587.4 (293.8) 1439.7 (229.1)
Reaction time for safe selections (70 & 90) ms 1587.9 (237.7) 1463.5 (261.5)
