|---|---|---|---|---|
| Primary | group-level correlation between individual cognitive parameters (motivational and metacognitive) and individual clinical sub-scores for inattention and hyperactivity/impulsivity on the ADHDRS scale. | 2 years | To evaluate whether individual cognitive profiles derived from computational modeling explain a portion of the variability in individual clinical profiles in ADHD (inattention, hyperactivity/impulsivity). | ClinicalTrials.gov |
| Secondary | Mean within-participant difference between ADHD treatment conditions (ON vs OFF) in the computational-model-derived motivational parameter from the Memory and Stroop tasks | 2 years | To assess, at the group level, the within-participant difference between sessions with and without ADHD treatment in the individually fitted motivational parameter of the computational model. This parameter, expressed in task point-equivalents, quantifies the motivational value associated with the allocation of mental effort during the neurocognitive tasks. For each participant and session, the parameter is estimated by fitting the computational model to the participant's observed effort-allocation behavior during the Memory and Stroop tasks. The outcome reported is the group-level mean of the individual ON-versus-OFF differences in the fitted motivational parameter, expressed in task point-equivalents | ClinicalTrials.gov |
| Secondary | Mean within-participant difference between ADHD treatment conditions (ON vs OFF) in the computational-model-derived metacognitive parameter from the Memory and Stroop tasks | 2 years | To assess, at the group level, the within-participant difference between sessions with and without ADHD treatment in the individually fitted metacognitive parameter of the computational model. This parameter, expressed in percent correct per second, quantifies the participant's subjective evaluation of her efficacy at making progress in the tasks, which contributes to the allocation of mental effort. For each participant and session, the parameter is estimated by fitting the computational model to the participant's observed effort-allocation behavior during the Memory and Stroop tasks. The outcome reported is the group-level mean of the individual ON-versus-OFF differences in the fitted metacognitive parameter, expressed in percent correct per second. | ClinicalTrials.gov |
