Abstract
|
|
|
Objectives: This study seeks to provide normative data on the production frequency and semantic typicality and familiarity of noun exemplars by semantic category for elderly individuals.
Methods: A total of 198 individuals participated in the study. In Experiment 1, participants were categorized into two groups: professionals involved in dementia care and primary care-givers of patients with dementia. They ranked 17 semantic categories based on the priority of the stimuli required for naming treatment. Forty-five normal elderly individuals (NEIs) participated in Experiment 2, in which they were administered a generative naming task. Seventy-eight NEIs participated in Experiment 3, where they rated the semantic typicality and familiarity of each noun exemplar obtained from Experiment 2.
Results: Experiment 1 revealed that ‘food (dish)’ was ranked as a top priority followed by ‘clothes’, ‘fruits’, and ‘body parts’. In Experiment 2, ‘body parts’ generated the highest mean of production frequency among 17 semantic categories. Results from Experiment 3 suggested that the semantic typicality was positively and strongly correlated with the familiarity ratings.
Conclusion: These results are clinically important and meaningful given that they provide preliminary guidelines to select stimuli for the naming treatment of individuals with neurogenic language disorders.
