Means (with SEs) for the proportion of trials in each cell formed by age group, image type, and item type (old vs new) for the four possible memory response bins

It is impossible to have a source correct response for new trials. Thus, incorrect old responses to new items are classified as a source incorrect (SI) trial if participants selected one of the two encoding tasks or as a source don't know (DK) trial if participants selected the Don't Know response option.
