Scores on the Author recognition test will computed by taking the total number of authors checked divided by 16, plus the total number of foils checked divided by nine [as foils were coded negatively, this will correspond to the standard scoring (see West & Stanovich, 1991).
We will first construct a model regressing the kids these days-reading scale on the author recognition test score. This will be done via robust maximum likelihood due to the Likert-scale nature of the dependent variable (see Li, 2016) using the following code:
MODEL:
ktd ON art;
We will then add age and conservativeness to the model using the following code:
MODEL:
ktd ON art age conservative;
