One way to estimate the temporal precision of vision is with judgments of synchrony or temporal order of visual events.

We also show that t...

Yet, these two accounts have never been systematically tested against each other, nor have their predictive powers been examined across different measures of the public's risk perception.

This study tested this hypothesis and examined how people judge their lev...
