Brief Summary
The purpose of the study is to examine the properties of the Automatic Story Recall Test (ASRT) and its parallel variants, as well as letter fluency and category fluency cognitive tests. Tests will be completed in crowdsourced populations, to derive normative data, and examine test properties in demographically diverse and cognitively impaired participants recruited and tested online.

Outcome Measures
Primary Outcomes (1)
Age, sex, and education adjusted normative scores for the Automatic Story Recall Task (ASRT) test variants derived via linear regression analysis.
Participants will complete a story recall task (ASRT), which will be administered in triplets (3x stories) with immediate and delayed recall assessed. Six different test phases, recruiting different participant samples, will be completed in which six parallel ASRT triplets will be separately evaluated. Normative data will be generated for each test triplet.
Baseline
Secondary Outcomes (9)
Normative data will be derived for shorter variants of the ASRT test battery derived via linear regression analysis.
Baseline
Age, sex, and education adjusted normative scores for the category fluency task performance derived via linear regression analysis.
Baseline
Age, sex, and education adjusted normative scores for the letter fluency task performance derived via linear regression analysis.
Baseline
The effect of demographic differences on task performance will be evaluated via linear regression analysis.
Baseline
Demographic and cultural biases will be examined via group or pairwise comparison of transcription error rate and scoring errors on a simple reading task.
Baseline
- +4 more secondary outcomes
Study Arms (3)
AMYWEB-Normative
This cohort assessed over six recruitment and test phases, will be sampled to be as closely representative of the demographic population as possible.
AMYWEB-Diversity
This cohort assessed over two recruitment and test phases will oversample participants from minority and mixed ethnic and racial backgrounds as well as participants from lower educational backgrounds.
AMYWEB-MCI
This cohort assessed and recruited over one test phase, will include participants with a reported diagnosis of mild cognitive impairment or dementia.
Interventions
No interventions/exposures will be administered or evaluated
Eligibility Criteria
Participants will be recruited online, primarily through crowdsourcing websites.
You may qualify if:
- First language must be English
- Residing in the USA
- Willing to participate in a study investigating speech and dementia
- Able to provide informed consent
- Access to personal computing device that is capable of audio and video recording, and able to connect to the internet
- Since key research questions are focused primarily on older-age speech and cognition, initial recruitment will be focused on older adult age brackets, which may be extended to younger adulthood if the desired sample sizes are not attained.
