Resumo(s)
This paper is the consensus of a workshop that
critically evaluated the utility and problems of video
playbacks as stimuli in studies of visual behavior. We
suggest that video playback is probably suitable for
studying motion, shape, texture, size, and brightness.
Studying color is problematic because video systems are
specifically designed for humans. Any difference in color
perception must lead to a different color sensation in
most animals. Another potentially problematic limitation
of video images is that they lack depth cues derived from
stereopsis, accommodation, and motion parallax. Nonetheless,
when used appropriately, video playback allows
an unprecedented range of questions in visual communication
to be addressed. It is important to note that most
of the potential limitations of video playback are not
unique to this technique but are relevant to all studies of
visual signaling in animals.
