By now you’ve probably noticed in your assigned readings

By now you’ve probably noticed in your assigned readings that the study of sensation and perception focuses on things you may have experienced but never given any thought to–for example, the “Purkinje shift”. We don’t think much about these phenomena because our world is full of them, and if we had to be conscious of every sensation and its accompanying perception that we ever experienced our brains would have little time for anything else (!) but research scientists have studied them in detail. This leaves us with the question–do these interesting and sometimes odd things matter? The answer is yes, but why and how varies depending on the particular phenomenon. Because there are real-life phenomena associated with everything discussed in our readings and dialoguing about them can bring theory and fact to life, for the remainder of our forum assignments we will be doing the following:

In the initial forum post, please describe how one of the phenomena mentioned in the readings explains an everyday event that you have experienced or observed and then suggest how this phenomenon might have serious consequences (so first its everyday occurrence and impact and then ways in which it can have serious impact).

For the purpose of this assignment, we will define “serious impact” as something that has negative consequences to health and safety of the self or others rather than something that is inconvenient or embarrassing. Not being able to distinguish colors under certain light may lead to getting home after a shopping trip only to find out an outfit isn’t the color you thought it was, which can be inconvenient and/or embarrassing. Not being able to distinguish colors under certain war zone conditions can be safety and life threatening.

Please be specific, thorough and concrete. Adding onto the end of a post a statement or two that something could be a problem is not sufficient. Additionally, saying you don’t know of any negative consequences isn’t permitted. Doing so will void your forum assignment points. You will need to explain how the phenomenon specifically has a negative impact. An example, described in Nicholas Wade’s 2000 “The Natural History of Vision” is below (NOTE: Because this one has already been applied, you must select another).  Unless discussing one of the more common disorders, like a lack of depth perception or hearing loss, please avoid “I think I have this” syndrome. This is something that medical students often fall prey to in the early years of medical school because they spend so much time studying human disorders, from the very common to the exceedingly rare.
