Adjusting the amount of damage to BiLex’s semantic and phonetic maps to match patients’ test scores (data for patient P8 are shown). (a) As lesion damage to the semantic map increases (left to right), the model’s semantic performance (PAPT score) decreases. The vertical line shows the amount of damage that best matches the target (horizontal line). (b) Semantic damage affects naming performance in both English (green) and Spanish (red). (c) Starting from the best-fit amount of semantic damage, additional lesion damage is applied to English and Spanish maps to match naming performance in both languages. As before, horizontal lines are the patient’s actual scores, and vertical lines are the best-fit amounts of lesion damage. The final lesion levels for semantic, English, and Spanish maps combine to reproduce the patient’s diagnostic scores in the model.
