<qa>  What is the name of the study that will be conducted in accordance with the Declaration of Helsinki2. Materials and Methods. 2.1 Study Design and Procedure. This study will employ a randomized, placebo-controlled, double-blind, repeated measures design consisting of two experimental sessions separated by at least 24 hrs, with participants receiving caffeine one day and placebo on the other day. The order of caffeine administration will be counterbalanced, such that half of the participants are randomly administered caffeine in the first and placebo in the second session, while the remaining half are administered caffeine and placebo in the reverse order. Prior to the experimental sessions, participants will complete informed consent, having been given an opportunity to read the study description and have any questions answered, complete demographic questionnaires, and experimental sessions will be scheduled. Participants will attend the BIOTIC Neuroimaging Research Lab at the QEII Health Sciences Centre Halifax, NS, for a morning i.e. testing beginning between 9-11 am testing session. Participants will be required to abstain from illicit drugs, over-the-counter medications, alcohol and cigarettes beginning at midnight of the previous day. SZ patients will not be asked to halt or pause any current medication regimen. Additionally, participants will be asked to abstain from caffeine including coffee, tea and cola for at least 6 hours prior to the test session to ensure adequate clearance of circulating caffeine half-life 2.5-4.5 hrs. Upon arrival at the laboratory, following self-report of adherence to pre-testing abstinence, drug treatment will be administered, EEG electrodes will be applied and, 30 minutes after drug administration, volunteers will be assessed with the test battery, presented in a randomized order to avoid order effects. All testing procedures will be carried out in accordance with the Declaration of Helsinki and following the approval of the relevant research ethics boards.
