In the present experiment we investigate brain activity while processing auditory and visual stimuli. During the experiment you are going to do a task on a computer monitor.

First your hearing will be briefly screened. Before the experiment starts you will perform a short training session in order to get used to the task procedure. The task involves detecting target stimuli shown on the monitor. The task is divided in 16 blocks with breaks between each block. During these breaks you will fill out a workload scale. After the experiment you will be asked to perform a short Working Memory Capacity test.

During the experiment, we will measure your brain activity with the help of electroencephalography (EEG). EEG only registers your brain activity and is totally safe. Practically, this means that during the experiment you will wear an EEG recording cap with 8 electrodes attached to it. Additional two electrodes will be placed on your nose and on your cheek. A drop of gel will be applied to electrodes. After the experiment you have the possibility to wash the gel out of your hair if you wish to do so.

You will be presented with additional auditory stimuli through in-ear tube earphones. The part of earphones that will be placed in the opening of your ear canal is made of foam and is one-time use only for hygienic reasons.

Before the experiment your hearing will be screened with pure-tone audiometry to ensure normal hearing.

As a participant, you should have normal or corrected to normal vision, normal hearing, be between 18 and 40 years and have no psychological disorders or history of neurological disease.

The experiment takes 2 hours. Participation is rewarded with 300 sek gift voucher.

The experiment takes place at Gösta Ekman Laboratorium, Frescati Hagaväg 9a.
