We studied development of categorical knowledge with speeded verification task (vote yes if pictured object is clothing). Stimuli were typical/atypical category objects and related/unrelated out-of-category objects (e.g., pants, glove, necklace, soup). Participants were 30 children with hearing loss (HL) between 5 to 15 yrs. Consistent with normal results, typical objects showed preferential processing (faster reaction times, fewer errors) and related out-of-category objects showed the converse. Performance was influenced primarily by age/age-related competencies Audiological status independently influenced results but to a lesser extent. Positive responses improved as degree of HL decreased, perhaps due to increase in quality and accessibility of conceptual representations with better hearing. Negative responses improved as age of identification/amplification/education decreased, perhaps due to improvement in decision-making proficiencies with more amplified experience and education.
