According to the book, one of the things that may prevent us from seeing
everything around us is that what we think we are going to see may affect
what we actually see. In other words, if we know that people don't change
appearance in the middle of an activity, we won't see the change. Which term
from Chapter 3 (pp. 88-92) best illustrates this concept?
O perceptual constancy
O top-down processing
O bottom-up processing
O perceptual set

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
