# Arousal Theory — AP Psychology Definition & Exam Guide

## Definition

Arousal theory suggests that humans are motivated to maintain an optimal level of arousal, which is the state of being alert and attentive. When arousal levels are too low, individuals seek stimulation to increase arousal, while when levels are too high, they engage in activities to reduce arousal.
