Time perception involves two distinct abilities: duration estimation (interval timing) and temporal order processing (sequencing). While temporal order deficits are well-documented in clinical conditions like schizophrenia (Coull & Giersch, 2022), individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) also show impaired time perception compared to neurotypical controls (Metcalfe et al., 2024). However, it remains unclear which specific aspects of time perception are affected in ADHD. This study addresses that gap through a two-part approach: (1) a scoping review of existing literature on duration and temporal order processing in ADHD, and (2) an planned empirical investigation of Temporal Binding—the perceived compression between cause and effect (Hoerl et al., 2020)—in adults with ADHD. Participants will complete two tasks: a temporal order task using the Libet Clock (Haggard et al., 2002) and an interval estimation task (Humphreys & Buehner, 2009). This design allows us to assess both timing and causality judgments. Our findings aim to clarify how time perception is altered in ADHD and contribute to a broader understanding of how neurological differences shape temporal experience.
