This master's thesis is focused on researching children's reception of theatre plays. The voice of children audience is rarely heard and, given the fact that children are the target audience of children's theatres, I believe that this subject is worth expanding on. In the theory section, I discuss a historical overview of both adult and children's theatre and explain many misconceptions related to it. I also create an overview of already conducted research of audiences, in both adult and children's theatres. In my own conducted research I use a model created by Rimac Jurinović (2022). By interpreting the results obtained by qualitative analysis I answer the main research question How do the examinees experience a theatre play intended for children as the target audience and what do they recall after seeing the play? and additional research questions What do the examinees expect from a play (horizon of expectations )?, Do the examinees exhibit an aesthetic distance and how does it manifest?, Which theatre conventions do children at the age 10 and 11 (children in primary education) comprehend?, Which peculiarities do they describe? and Which information do the examinees receive during the play?. Children at the age 10 and 11 (children in primary education) understand theatre as a system of symbols and have the necessary knowledge to partake in the process of creating a play. I believe theatre professionals are obligated to recognize children's ideas and to create theatre related content that is first and foremost made with children in mind. With the master’s thesis, I wish to encourage theatre and education experts to further explore children audience and to point out the importance of raising new theatre audiences. The literature refers to children audiences as the kidnapped or captive audience since children depend on the adults decisions. The focus of the thesis is precisely on children and their reception of theatrical events.
