Background: Tasks using speech and language have proven to be useful in assessing for neurodegenerative diseases and cognitive decline. Specifically, deficits in naming have been associated with various degrees of cognitive impairment in those with dementia. Method: The Continuous Picture Naming (CPN) task was administered as part of a new computerized cognitive assessment tool, the California Cognitive Assessment Battery (CCAB), to 309 aging older adults (aged 56‐89, 40.6% female) with a six‐month and one‐year follow‐up to assess for cognitive changes due to aging. The CPN task measures how fast and accurately a subject can verbally produce the names of a series of items pictured onscreen. The battery scores tasks automatically and utilizes an online speech‐to‐text transcription, consensus automated speech recognition (CASR), to transcribe responses on verbal tasks. Result: Response times and accuracy were on CPN collected and analyzed to observe for effects on age and education. The analysis showed that age and education were significantly associated with the task's performance. Overall, CPN performance demonstrated good test‐retest reliability at the six‐month (r =.76, p<.001) and one‐year (r =.74, p<.001) follow‐ups. Moreover, a significant relationship was observed between the total time spent and the total errors on the task. Conclusion: Overall, the CPN demonstrates good reliability in tracking changes in cognition. Ongoing evaluation of the CCAB will aid in assessing cognitive impairments in aging populations.
