Table 2.

Principal factors identified from a wide variety of naming errors during picture naming. Naming errors that load strongly (> 0.5) with each factor are marked in bold, allowing for behavioural interpretation. In addition, the correlation between age, education, months post onset and lesion volume are shown.
