People display consistent recency and primacy effects in behavior and neural activity across perceptual and value-based judgments
Yoo, Bahg, Turner and Krajbich, Cognitive, Affective, & Behavioral Neuroscience 25(4), 2025, 923-940. Participants continuously reported the mean intensity of stimulus sequences in perceptual and value-based tasks, behaviour and fMRI. Weighting curves were highly similar across tasks, typically a strong recency bias with a smaller primacy bias. Evidence-tracking activity in the cuneus in both tasks and in the left dorsolateral prefrontal cortex in the value task. Stronger primacy than recency went with more activity in cognitive control regions. Authors conclude people give recent information too much weight when judging the past and that overcoming it may depend on cognitive control. No sample size used.
