Thus, because the two signals are not equal and the drum is seen to move (Wertheim,1994). Consequently, when using the inferential theory of perception the criticism is that the drum appears to be stationary even after once vection is saturated (Wertheim,1994).
Conclusion
For the purposes of this discussion we focused on evaluating two fundamental approaches to explaining perception; Direct perception and Inferential Theory. We found that the direct perception theory describes an approach, which asserts that the visual world reveals itself as an organized pattern of light. This pattern, called the optic array, is composed of information because it has specific structural features, described as invariants. Therefore using this theory, the process of perception is believed to be a process of "picking up" these invariants from the optic array.
On the other hand the investigation demonstrated that the inferential theory of perception asserts that the perception of motion of objects, inclusive of the visual world, is a result of the outcome of a comparison process between two neural signals. The first signal or the "retinal signal," is composed of retinal afferents in which the characteristics of movement of the image across the retinal surface are encoded. The second signal, or the "extraretinal signal," encodes...
