SUMMARY OR ABSTRACT

Text of Note
Object recognition is imperfect; often incomplete processing or deprived information yield misperceptions (i.e., misidentification) of objects. While quickly rectified and typically benign, instances of such errors can produce dangerous consequences (e.g., police shootings). Through a series of experiments, this study examined the competitive process of multiple object interpretations (candidates) during the earlier stages of object recognition process using a lexical decision task paradigm. Participants encountered low-pass filtered objects that were previously demonstrated to evoke multiple responses: a highly frequented interpretation ("primary candidates") and a lesser frequented interpretation ("secondary candidates"). When objects were presented without context, no facilitative effects were observed for primary candidates. However, secondary candidates demonstrated evidence for being actively suppressed. When primed with scenes semantically relevant to primary candidates, the suppression of the secondary candidate was eliminated while primary candidates continued to lack facilitation. However, when primed with scenes consistent with secondary candidates, secondary candidates were once again suppressed. Moreover, primary candidates were facilitated. Overall findings suggest that primary candidates may actively suppress competition from lesser candidates in the earlier stages of object recognition. This effect is strengthened when the primary candidate is challenged but removed when it is reaffirmed.
