Brief summary

Standardized tests such as the Scholastic Aptitude Test (SAT) and the brazilian National High School Exam (ENEM) give more time for students with Attention Deficit and Hyperactivity Disorders (ADHD) to complete the exam. The goal of this study is to find out if giving students with ADHD more time on tests actually helps them. Additionally, the research aims to find out if more time helps students without ADHD too or not, or even if it only helps students with certain traits.

Detailed description

Initially, the participants of this study will fill out forms and questionnaires online. Then, they will go through a psychiatric evaluation, where they will talk to a psychiatrist, and neuropsychological testing, where they will do some mental activities. Later on, they will do a mock test of the ENEM, with and without extra time.

Intervention model description

Participants will be assigned either to the ADHD group or non-ADHD group based on diagnosis. Both groups will receive the same intervention, which is to perform three academic exams based on the Brazilian National High School Exam (ENEM) under three different time conditions (40 minutes, 50 minutes and 60 minutes). The order in which they will perform each exam and with which time condition will be randomized. In order to emulate real-life conditions in which students compete for college entry and motivate them, the participants will be competing for valuable prizes (ebook readers).
