Resumen de Feature types and object categories: Is sensorimotoric knowledge different for living and nonliving things?

• Some models of semantic memory claim that items from living and nonliving domains have different feature-type profiles. Data from feature generation and perceptual modality rating tasks were compared to evaluate this claim. Results from two living (animals, fruits/vegetables) and two nonliving (tools, vehicles) categories showed that sensorimotoric features were important in object knowledge across both domains. In addition, significant cross-domain similarities and within-domain differences indicated that feature profiles were not determined simply as a function of the living and nonliving domain distinction. The current data support a model of semantic memory rooted in perceptual and motor processes with reduced salience for the “living/nonliving” construct.
