Subclaims¶

q3 i0 Non-decision time was equivalent during the stop-signal and no-tone tasks (BF01 = 5.73; d = 0.07), with no group main effect or interaction. → Fosco 2019

Evidence¶

Fosco 2019¶

Fosco, W. D., Kofler, M. J., Alderson, R. M., Tarle, S. J., Raiker, J. S., & Sarver, D. E. (2019). Inhibitory Control and Information Processing in ADHD: Comparing the Dual Task and Performance Adjustment Hypotheses. Journal of Abnormal Child Psychology. https://doi.org/10.1007/s10802-018-0504-9

q3 · i0 · causal · r2

Tier 2 Bayesian mixed ANOVA of drift-diffusion parameters in 144 children. "non-decision time was equivalent during the stop-signal and no-tone tasks" (d = 0.07), inconsistent with the dual-task hypothesis prediction of disrupted stimulus encoding and response execution.

"There was moderate evidence that non-decision time was equivalent during the stop-signal and no-tone tasks (BF01 = 5.73; d = 0.07). There was also significant evidence against a main effect of group on non-decision time (BF01 = 5.43; d = 0.01), and against the group x task interaction (BF01 = 4.30)."

• Children with and without ADHD show equivalent increases in response caution when stop trials are introduced — related
• Children adopt a more cautious response strategy (higher boundary separation) when intermittent stop trials are introduced — related
• Introducing intermittent stop trials does not change processing speed (drift rate) in children with or without ADHD — related
• Equivalent performance-adjustment effects hold when clinical control and neurotypical children are analyzed separately — related
• Go-trial response times are slower during the stop-signal task than the no-tone task, with no diagnostic group difference — related
• Reward does not alter the speed or variability of response execution in either stop signal task — related
