Note. The intercept represents the overall mean accuracy, and the coefficient of a variable represents the effect of the variable as the amount of deviation from the overall mean. ACT = action pictures; sev = severe; HP = home practice phase; PR = practiced pictures; TR = treated pictures; mod/sev = moderate-to-severe.
