Naming Living vs. Non-Living Items: RSDT Analyses for Snodgrass Picture Naming and Naming from Definition

Control participants (N), mean control proportion correct (%), control standard deviation (SD), AC’s proportion correct (AC’s score), correlation between tasks, and t- and p- scores for a RSDT analysis comparing performance for living versus non-living items, referenced to controls for both Snodgrass Picture Naming and Naming from Definition. Note: for this particular Snodgrass Picture Naming analysis, control values came from 19 healthy undergraduates who named the 60 items. The categories of animals, fruit, and vegetables (living) and tools, vehicles, and furniture (non-living) are included in these analyses.
