Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Age 15-35, right-handed, normal seeing.

Exclusion criteria

Exclusion criteria: * Wearing braided hair (which makes recording of reliable EEG signals nearly impossible) * Insufficient mastery of the Dutch language * Neurological problems (including epilepsy) * Use of drugs that may influence the task performance * Due to the use of MRI scanning, several additional criteria will apply. The participants will have to fill out a detailed questionnaire covering safety aspects of the research in relation to the 3 Tesla magnetic field and the MRI environment. These criteria are: * MR incompatible implants in the body (such as ear prothesis or other metal implants) * Any risk of having metal particles in the eyes due to manual work without proper eye protections * Tattoos containing red pigments * (Suspected) Pregnancy * Claustrophobia * The refusal to be informed of structural brain abnormalities that could be detected during the experiment

Design outcomes

Primary

MeasureTime frame
The study parameters are the dynamics in the observed EEG and fMRI data during the perceptual and memory tasks, which will be compared to the predictions of a mathematical model of evidence accumulation. Evidence accumulation can take place either on the basis of information directly available to the senses, or on information only present in memory.

Secondary

MeasureTime frame
To use the information about the neural correlates of evidence accumulation to extend and improve our mathematical models of decision making, such that they can make predictions about the interactions between brain areas.
