How does our body shape our memories?

The aim of the study is to better understand the perception of one's own body and to elucidate how multisensory information contributes to memory. Not only does new knowledge within this area have great scientific value, but it can also help with increasing our understanding of neurological and psychiatric disorders with disturbed body perception, for example, bodily neglect symptoms after stroke.

To participate in this study, you must be in good health, you must not suffer from any neurological or psychiatric complaint and must not use any medication to treat such ailments. We are looking to recruit right-handed adults, with normal or corrected-to-normal vision. Due to the nature of the experiment, a good grasp of the English language is necessary.

Procedure
During the experiment, you will be asked to lie comfortably on a bed and wear a set of head mounted displays (HMDs). Above your head, two cameras will be filming your body, very comparable to what you would see if you would look at yourself. What the cameras film will be displayed on the HMDs. A laptop will be placed on your legs, which you will see through the HMDs. On this laptop, you will see different word-pairs displayed on the screen that you should try and remember. Then, your task is to indicate which word has more vowels (a, e, i, o, or u). The instructions for this task will be displayed on the laptop-screen before starting the experiment.

During the experiment, your arms and torso will be repeatedly touched with a stick in a random manner. Sometimes, what you see and what you feel will not be the same. This may feel strange but is completely normal. There will be many breaks (indicated on the laptop-screen) where you may rest your eyes.
This first part of the experiment will take approximately 30 minutes. After that, you will be seated at a table and do a computer-based task, in which your memory of the words will be evaluated, requiring you to respond on a scale regarding the confidence you have in your memory of the words. This part will again take approximately 30 minutes.

Compensation
For your participation in the study, you can choose between getting a movie ticket directly or SEK 200 paid through the Karolinska Institutet's salary office (the latter is taxable).
