Normative data on 372 stimuli for descriptive naming

Naming problems are common in patients with dominant temporal lobe epilepsy (TLE) and anterior temporal lobectomy (ATL). Descriptive naming may be an especially useful procedure for the presurgical workup of candidates for ATL, given its sensitivity for detecting subtle naming problems in TLE and its localization to anterior temporal regions that are commonly targeted for resection in ATL. This study provides normative data pertaining to difficulty level (accuracy and reaction time) on 372 descriptive naming items in four conceptual categories: common non-living, common living, unique non-living, and unique living things. These data will be useful to investigators who wish to develop protocols for clinical assessment or stimuli for functional imaging paradigms aimed at assessing the function of the anterior temporal lobes.
