Aktiver Komparator: Young adults
Participants aged between 18 and 40 years old.
|
We will present emotional expressions to participants.
Their task will be to determine which emotion is expressed by each face.
Participants' eye movements and brain activity will be recorded while they explore the face.

Aktiver Komparator: Healthy old adults
Participants aged between 65 and 95 years old.
|
We will present emotional expressions to participants.
Their task will be to determine which emotion is expressed by each face.
Participants' eye movements and brain activity will be recorded while they explore the face.

Experimental: Patients with Alzheimer's Disease
Participants aged between 65 and 95 years old with a diagnosis of Alzheimer's Disease.
|
We will present emotional expressions to participants.
Their task will be to determine which emotion is expressed by each face.
Participants' eye movements and brain activity will be recorded while they explore the face.
