Abstract
Unity and prototypicality are important visual aspects of product design. These design principles were operationalized by modifying line drawings of existing products. The results of four experiments provide evidence that these two factors positively affect aesthetic response. These effects were strongest when visual properties were the sole basis of judgment and when design variations were easily compared. However, they persisted when aesthetic aspects were combined with other product information and when comparing design features was difficult. The effect of unity was found to be superadditive, suggesting that it has a relational, "all-or-none" character. Finally, regression analyses show that direct effects of the design modifications on aesthetic response exist in addition to possible indirect effects that are mediated by perceived typicality.
