***Note 1: The smell and taste stimuli are very simple solutions and are vegan-friendly. No animal products are used in our studies.

***Note 2: The study uses Inquisit Web to host the online forms and tasks (i.e., Information Sheet, Consent Forms, questionnaires) and requires the Inquisit Player installed on your machine to work. Inquisit Web is a web application that enables psychological and behavioural researchers to design and administer a wide variety of psychological measures over the web. The app enables stimuli presentations and response time measurement with high timing precision required by many commonly used psychological measures. The app is completely harmless and can be easily uninstalled after a session. More information can be found at
