We are look­ing for par­tic­i­pants on a reg­u­lar basis and con­duct on-site as well as online studies! 

We also pro­vide infor­ma­tion con­cern­ing par­tic­i­pa­tion in stud­ies con­duct­ed in Ger­many. Please use the lan­guage switch.

At the moment we espe­cial­ly need more male participants!

If you would be inter­est­ed in par­tic­i­pat­ing in this research and cre­at­ing a healthy habit, please fol­low this link: 

Your infor­ma­tion will remain con­fi­den­tial, be held secure­ly and not divulged to any third par­ties. Your infor­ma­tion will be used for research pur­pos­es only and you will be free to with­draw from the study at any time. This study is part of a col­lab­o­ra­tive effort between the Uni­ver­si­ties of Helsin­ki, Ams­ter­dam, Cam­bridge, and Konstanz. 

We hope to hear from you soon,

We are look­ing for par­tic­i­pants to par­tic­i­pate in a study designed to inves­ti­gate people’s rela­tion­ship with var­i­ous com­mon food snacks. In the exper­i­ment, the par­tic­i­pant will be asked to come nei­ther hun­gry nor full (at least 1 hour fast­ed). Then, you will be asked to sit in a lab room and after some ini­tial rat­ings on your con­di­tion (e.g., Hunger), you will rate pic­tures of food on a com­put­er screen, and answer a few ques­tion­naires about your eat­ing habits and your gen­er­al mood, for approx­i­mate­ly 1.5 hours in one session.

Par­tic­i­pants, tak­ing part will be com­pen­sat­ed with 15 euros (tax­able income) in the form of a vouch­er (e.g Wolt, Finnk­i­no, Bookbeat)

If you are inter­est­ed in par­tic­i­pat­ing in the exper­i­ment, please com­plete this sur­vey ( A mem­ber of our team will get in touch assum­ing you are eli­gi­ble for the study.
