Previous research has found mixed results for a link between executive function and perspective-taking. One proposed reason for this is that perspective-taking during comprehension tasks may not be internally reliable. This dissertation presents two large individual differences experiments with multiple perspective-taking during comprehension and executive function measures. We aimed to see: (1) whether people were consistent in their ability to take perspectives during comprehension, (2) if the typical tasks used in this area were reliable, and (3) whether executive function measures predicted perspective-taking ability. We found a lack of reliability of some of the most commonly used perspective-taking during comprehension tasks, and no evidence that inhibition control or working memory predict perspective-taking ability. Sparse correlations between the perspective-taking tasks lead us to propose that perspective-taking during comprehension should be considered in a more granular way.
