![]() When we make perceptual decisions about the world around us, they are accompanied by a metacognitive sense of certainty, or confidence, in whether those percepts are correct. Great progress has been made towards understanding the internal statistical models that guide our perceptual decision-making and corresponding confidence ratings. Our findings explain peripheral inflation, especially under inattention, and suggest future experiments that might reveal the noise expectations used by the visual metacognitive system. Further, only one model successfully captured previous empirical results, which showed a selective increase in confidence in incorrect responses under performance reductions due to inattention accompanied by no change in confidence in correct responses this was the model that implemented Bayesian estimation of peripheral noise, but using an (incorrect) symmetric rather than the correct positively skewed peripheral noise prior. Models that failed to optimally estimate noise exhibited peripheral inflation, but only models that explicitly used peripheral noise priors-but used them incorrectly-showed increasing peripheral inflation under increasing peripheral inattention. Here, we examined central and peripheral vision predictions from five Bayesian-inspired noise-estimation algorithms under varying usage of noise priors, including effects of attention. However, despite previous Bayesian hypotheses about metacognitive noise estimation, no work has systematically explored how noise estimation may critically depend on empirical noise statistics, which may differ across the visual field, with central noise distributed symmetrically but peripheral noise positively skewed. Previous literature suggests inflation stems from errors in estimating noise (i.e., “variance misperception”). However, observers can be overconfident relative to accuracy, termed “subjective inflation.” Inflation is stronger in the visual periphery relative to central vision, especially under conditions of peripheral inattention.

Recent Examples on the Web In ways large and small, Cohen’s functionally unlimited resources have rewired more than a half-century of Mets self-perception, even if last year, like so many before, ended in disappointment: a quick playoff exit after a 101-win season.
