Study Summary
Participants will be assigned to complete computerized estimation tasks for which there is a component of accuracy, such as estimating the duration of sounds. Participants will be told that the task is used as an early diagnostic tool to detect those at risk for a medical condition (e.g., Parkinson's disease, Alzheimer's disease). Instructions will be given to participants telling them that accuracy on the task is associated with the disease, whereas those who are not at risk of the disease tend to either overestimate or underestimate the duration of the sounds. The investigators examine whether such instructions about the purpose and diagnosticity of the tasks biases participants' responses to the tasks, leading them to purposefully be more inaccurate in their estimates.
Primary Outcome
The estimate of the length of time elapsed during the sound file
Interventions
- OTHER Instructions about Overestimates
- OTHER Instructions about Parkinson's
- OTHER Instructions about Underestimates
- OTHER Instructions about Alzheimers
