All of our experiments are reviewed and authorized by the Hungarian Egyesített Pszichológiai Kutatásetikai Bizottság (Unified Psychological Ethics Committee). Participation in all our studies in voluntary, and consent can be revoked at any stage of the experiment without justification.
Age range: 14-24 months (or older)
Question(s): How do children behave in certain interactive, playful situations?
Assumption: Children use their knowledge and predictions whilst playing, and their behavior can serve as evidence whether they possess certain knowledge and understanding of the world or not.
Procedure: We use carefully designed, scripted scenario to find out how children behave in certain situations. We record these sessions, and later code and analyze the behavior of children – such as what and how long were they looking for, or what kind of choices they made during the play. We code their behavior based on previously set criteria relevant to the research question.
Example: With 14 months old children observing the event, an experimenter hides two whistles in a box. Following this, the experimenter takes out either just one or both of the whistles, and we observe how long children will look for a whistle in the box. Based on the results, it appears that children are able to keep in mind the number of objects hidden and taken out from the box, as well as the knowledge of the other participant about the situation (For more details, see our 2013 Newsletter, study: “Sípok a dobozban”).
