Note. All models used trial-level data. Each model includes the second-degree polynomial of age (i.e. including linear and quadratic functions of age). Condition is a binary variable describing whether stimuli (words and shapes) were self- or other-judged in the words task, and self- or other-associated in the shapes task. Valence is a binary variable describing whether words were positive or negative. MaRs-IB is the proportion correct on the Matrix Reasoning task, included as a covariate to control for age-related differences in reasoning. Testing group size denotes the number of participants in the same testing room. FA is individual level false alarm rate in the words task.
Indicates interactions for individual terms and all lower-level interactions.
