Sound Estimation and Accuracy Task

NCT02271685 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 600

No results posted yet for this 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.

Conditions

Interventions

OTHER

Instructions about Overestimates

Participants are told that overestimating the duration of sounds are associated with low disease risk.

OTHER

Instructions about Parkinson's

Participants are told that the task is about risk of Parkinson's disease.

OTHER

Instructions about Underestimates

Participants are told that underestimating the duration of sounds are associated with low disease risk.

OTHER

Instructions about Alzheimers

Participants are told that the task is about risk of Alzheimers disease.
