Cognitive Psychology - Perception Pt1 - Visual Perception

The basic perceptual process (focusing on the visual sense) and some examples of how what hits our eyes is not the same as what we see (experience).
This is a lecture video for a university course in Cognitive Psychology taught by Dr. Brian W. Stone. You may wish to play it at x1.25 speed. As with anything taught at the undergraduate level the information here may be simplified, and at higher levels of study there is more nuance to all of it.

Just an observation, I was shown both the cow and dog 2 years ago in my cognition class and I didn't remember them or see them this time, until you said something. I just thought that was interesting. Probably just highlights how crappy my memory is getting :D

haha, it may not point to much about your individual memory ability. For the most part, we talk about a lot of things like this in psychology as overall effects that average out across a large sample of people. So we find an effect when we look at many people, but for one single person, their performance on a particular day (or whether a memory 'clicks' for them) often has more to do with the randomness of that particular day/moment and other factors. So measuring individual memory performance is "noisy", but we can compare groups across different situations to discover these overall patterns and effects.
