Table 1.

Mixed-effect logistic regression analysis of the effect of within-task repetitions and task order on writing functions and planning to use functions. The models with the best fit are shown for each type of decision and experiment: the gradual repetition level model for Experiment 1 and the more-than-once (greater than 1) model for Experiments 2 and 3. (Full tables of alternative models are included in table ST2 in the electronic supplementary material

).
