q3 i? In the perceptual detection task, detection probabilities increased with larger magnitudes and longer durations for both angular and speed discrepancies, and RTs decreased with magnitude. → Inmaculada Márquez & Mario Treviño 2025

q3 · i? · causal · r2

Perceptual detection task in which participants judged brief changes in a moving dot's direction or speed over durations from 50 to 1000 ms. The article reports highly significant effects of magnitude and duration on detection probability (e.g., angular η2G = 0.806) and smaller RT effects (η2G = 0.106 angular; 0.047 speed), consistent with "temporal i ntegration in perceptual decision-making".

"Detection probabilities increased with both larger magni- tudes and longer durations, for both angular (Fig. 3b) and speed (Fig. 3c) discrepancies."
