What does 'incongruity' refer to in Berlyne's aesthetic characteristics?

'Incongruity' in Berlyne's aesthetic characteristics refers to the extent of apparent mismatches between elements. This concept emphasizes how unexpected pairings or contrasts within a design can provoke curiosity and engagement. In design, when elements do not traditionally fit together or deviate from our expectations, it can capture attention and lead to a greater aesthetic experience. This mismatch encourages viewers to think critically about the relationships between various design components and enhances emotional responses, making the experience of the design more memorable and dynamic.

In contrast, the other options focus on uniformity or alignment, which tend to prioritize cohesion rather than incite curiosity through contrast or mismatch. Therefore, they do not embody the essence of incongruity as described by Berlyne.
