Time-of-day effects on eyewitness reports in morning and evening types

Figures & data

Figure 1. Density plot for distribution of rMEQ (reduced version of the Morningness–Eveningness Questionnaire) scores in participants with evening and morning chronotype in the final sample.

Figure 2. The likelihood of observing the data if the true effect size is small, medium, or large, compared to the null hypothesis of no effect of testing optimality on quantity of free (Panel A) and cued recall (Panel B), and accuracy of free recall and cued recall (Panels C and D respectively).
