The phenomena of in-group favoritism and out-group discrimination arise as early as preschool age. Living in increasingly diverse societies, it is therefore important to research these behaviors with children of that age. However, there exists no widely applicable tool that allows to measure in-group out-group bias in young children.

The integration of Augmented Reality (AR) in teaching concepts allows for the visualization of complex learning contents and can simultaneously enhance the learning motivation. By providing Tangible Augmented Reality (TAR), an AR learning environment receives a haptic aspect and allows for a direct manipulation of augmented learning materials. However, manipulating tangible objects while using handheld AR might reduce the intuitive use and hence user experience. Users need to simultaneously control the application and manipulate the tangible object. Therefore, we compare the differences in intuitive use and user experience evoked by varied technologies of knowledge presentation in an educational context. In particular, we compare a TAR learning environment targeting the learning of the anatomy of vertebrates to its smartphone-only and AR-only versions. The three versions of the learning environment only differ in their method of knowledge presentation. The three versions show a similar perceived intuitive use. The TAR version, however, yielded a significantly higher attractiveness and stimulation than AR-only and smartphone-only. This suggests a positive effect of TAR learning environments on the overall learning experience.
