Input Enhancement Dataset

This is the dataset of the results of an input enhancement experiment consisting of 4 groups: true control (no treatment), control (plain text), experimental 1 (instances of 3rd person -s colored red and underlined, and experimental 2 (instances of 3rd person verbs were enlared to 2x size). The assessment materials (available via IRIS repository) were a 30-item grammatical judgement task, 20-items of which related to 3rd person -s. The other 10 items were distractor items and not counted towards the final score. The maximum possible score is therefore 20/20.
