Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Event-related potentials (ERPs) | 30 minutes post-intervention during both test sessions | Average neuroelectric brain response measured in microvolts. Event-related potentials include N2pc (visual search) and P300 (visual search, AX-CPT and N-Back) |
| Secondary | Response accuracy | 30 minutes post-intervention during both test sessions | % of correct responses during performance of visual search, AX-CPT and N-Back |
| Secondary | Reaction Time | 30 minutes post-intervention during both test sessions | Average time from target appearance to correct behavioural response (measured in milliseconds) during performance of visual search, AX-CPT and N-Back |
| Secondary | False alarms | 30 minutes post-intervention during both test sessions | Number of responses to non-target stimuli during performance of visual search, AX-CPT and N-Back |
| Secondary | d' | 30 minutes post-intervention during both test sessions | A measure of signal detection sensitivity, obtained by the following formula: d' = zHits = zFalseAlarms, during performance of visual search, AX-CPT and N-Back |
| Secondary | C | 30 minutes post-intervention during both test sessions | A measure of response bias, obtained by the following formula: C = -0.5(zHits + zFA), during performance of visual search, AX-CPT and N-Back |
| Secondary | Checklist of Drug Related Symptoms | 1 hour post-intervention during both sessions | Assesses physical symptoms potentially arising due to drug administration, including nausea and headache |
