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.

Study Arms (2)

ADHD group

EXPERIMENTAL

Participants with Attention Deficit Disorder/Hyperactivity (ADHD) diagnosis who will take three equivalent academic exams, having 40 minutes (standard time), 50 minutes (25% increase) and 60 minutes (50% increase) to complete the exam.

Behavioral: Extended time 25%; Behavioral: Extended time 50%

Control group

ACTIVE COMPARATOR

Participants without Attention Deficit Disorder/Hyperactivity (ADHD) diagnosis who will take three equivalent academic exams, having 40 minutes (standard time), 50 minutes (25% increase) and 60 minutes (50% increase) to complete the exam.

Behavioral: Extended time 25%; Behavioral: Extended time 50%

Interventions

Extended time 25% BEHAVIORAL

Considering a standard time of 40 minutes, participants will receive 50 minutes to complete the exam.

Model Details: 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).
