Computer animation is an excellent manipulative tool to study how evaluative behaviors such as identification, recognition, and assessment are influenced by visual features such as size, shape, patterns of light and dark, and movement. However, when designing experiments that utilize this technique, it is important to understand the differences in vision between humans and other animals and the implications that these differences have as to what types of hypotheses are appropriate to test. I will go over these differences, as well as give a brief overview of how to use Adobe products to animate photographs. Finally, by highlighting some findings from my own work with jumping spiders, I will demonstrate how computer animations can be combined with cues in other modalities to test how different modalities interact in the minds of receivers.
