In informal learning settings the important information often is arranged all around the visitors. For example, thinking of a museum or a historical place, more or less impressive architecture comes to ones mind with galleries, where exhibits are arranged all over the walls and throughout the rooms. A series of experiments showed that the arrangement of the information on the walls of a room influenced memory for related pieces of information. Now an experiment (pre-registered, based on a power anaylsis) will examine if the architectural features of a room, namely walls and corners, also influence how visitors categorize the presented information: Using AI, artworks were created belonging to four different styles (painting, photorealistic, animé, low poly) and four different motifs (portraits, landscapes, stilllifes, genre). Participants wearing HMD glasses will explore a virtual room with 24 artworks on the four walls sorted wallwise either by style or motif (between). Afterwards they have to rate similarity of new pictures that either show the same motif but different styles or are of the same style but show different motifs. It is expected that participants are more aware of the categories according to which the artworks in the room were sorted wallwise and therefore will judge similarity depending on these categories: After exploring a room with pictures sorted wallwise by motif (vs. style) two pictures presenting the same motif (vs. style) should be rated similar more often. Findings could help to understand how rooms may structure the cognitive processing of information.
