Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Following the task, all participants will be told that the tasks used are actually NOT diagnostic of the diseases in question, and that deception was used to learn how people respond to instructions about how a task can be used for diagnostic purposes.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Overestimate Parkinson's
People are told that overestimates on the sound estimation task are associated with being healthy and having a low risk of Parkinson's disease, whereas those who are accurate are more likely to develop the disease later in life.
Instructions about Overestimates
Participants are told that overestimating the duration of sounds are associated with low disease risk.
Instructions about Parkinson's
Participants are told that the task is about risk of Parkinson's disease.
Overestimate Alzheimers
People are told that overestimates on the sound estimation task are associated with being healthy and having a low risk of Alzheimers disease, whereas those who are accurate are more likely to develop the disease later in life.
