SOURCES OF DISAGREEMENT IN OBJECT NAMING

Two experiments examined the processing of objects with low name agreement. Experiment 1 compared naming latencies for objects with three different types of name disagreement to those for matched control objects with very high name agreement, Objects with low name agreement due to abbreviations (e.g. phone) were named no more slowly than were control objects. Objects with multiple names (e.g. couch, sofa, settee) and objects often given incorrect names (e.g. spider for ant) took longer to name correctly than did matched controls. These results were confirmed in a second naming experiment using a revised set of high-name-agreement control stimuli. In Experiment 2, subjects carried out an object decision task using the revised stimulus set. Subjects could recognize objects with multiple names as quickly as those with high name agreement. Objects often given incorrect names were recognized by subjects more slowly than were high-agreement matched stimuli. The pattern of data suggests that the delay in naming latency due to the availability of more than one correct name arises after structural recognition. In contrast, the slowed naming of objects often misnamed would seem to originate from difficulties encountered at or before the structural stage of recognition.
