-The `data.key_press` value is a numeric key code indicating which key the subject pressed. The function `jsPsych.pluginAPI.convertKeyCharacterToKeyCode` converts the character representation of a key into the numeric representation (e.g., calling the function on the value `'f'` generates the value `70`). If this numeric value matches `data.key_press` then `data.correct` will be `true`. Otherwise, it will be `false`.
+The `data.key_press` value is a string representation of the key the subject pressed. We can compare this with the `data.correct_response` value, and assign this computer value to a new property `data.correct`.
