Final Post

            Perceptual processes provide us with details from the behind-the-scene processes that is occur when we perceive the world we live in and go from day to day. A sequence of processes occurs when we determine our experience of reactions to the environment and stimuli within it. Perception is a semi complex topic that has many different processes that occur in our body that help us find a sense of what is currently going on. Throughout this course we learned about the brain and the processes that happen, vision and how light is related and helps perception and also our visual cortex. We also learned about how we perceive objects and scenes around us, some individuals do not see the environment or people the same way as others, diseases or impairments can cause face blindness or other blindness. Motion was also another topic that helps us perceive and understand the environment along with color. To be able to function normally we need to be able to understand and notice depth and size and also hear sounds, which relates to pitch. Without either of these things within perception it would be difficult to perceive things accurately and successfully.  Speech, one of the most complicated processes involved in perception because it is the most complex visual scenes. Lastly, the senses chemical and the cutaneous are very important for perceiving things, like identifying odors, perceiving texture and experiencing pain. We all need things to help identify us where we are, what are we touching and what is that smell. The five senses definitely help us perceive the world one smell or touch at a time. This course taught me so much in this short period of time, until now I didn’t know that it took multiple processes to see and successfully navigate through the environment. Without any of these processes above it would make perceiving an object or the environment difficult, all are different and unique but they come work together and help us experience perception.
            My favorite part of the course was the chapter that discussed visual attention; I found this to be the most interesting and enticing material in the course. All individuals experience and perceive things differently; we make sense and pay attention to different things within our environment. The videos within the lectures will definitely be unforgettable to me, the ‘how many passes does the white team make’, the Yale and the sign experiment. I found this so amusing and interesting that some people do notice a moon walking bear through the screen or a different person handing you papers for an experiment and others do not. The sign video really showed how little we perceive something’s and how much detail we put into other things we perceive. To think that some people who first went from talking to a male to a female didn’t notice at all is mind blowing but that’s what makes it interesting! Inattentional blindness is an extremely interesting process to me, I can’t believe people do not see a stimulus that is right in front of them. It makes me wonder what people see and detect that I don’t in everyday life, am I missing out on certain entertaining things or context clues that will make my life easier? And for me to think that people do not see the same things that I notice is weird but interesting at the same time! It makes me wonder why doesn’t everyone pay attention to the same things in life!?
            People with autism see things differently that other individuals without the disorder don’t. I find this real-world issue even more interesting, because not only do people who do not have any disorders sometimes don’t share a common attention but other people who are diagnosed with autism see things completely different. They have different fixations points and how and where they direct their attention, this has to deal with social situations and how they might perceive the environment. This can be caused by sensitivity to the temporal lobe something that non-autistic people don’t have.

  1. Visual attention is interesting to me as well and quite comical! Watching a video of customers walking up to a counter to check-in to a seminar where the customer would be greeted by the sales rep behind the counter and would engage in conversation, presenting ID, filling out paperwork and would even hand the sales rep a credit card for their entrance payment into the seminar. Here is were it becomes comical: In the midst of it all the rep would bend down for a split second behind the counter to grab the customers paperwork and a COMPLETELY DIFFERENT SALES REP would pop back up & then take over the rest of the check in. **The idea of the experiment was to see if the customer would realize that the sales rep was a completely new person wearing a completely different shirt, etc. It was amazing how many customers had no visual attention and didn't realize they were dealing with a new person! It was very amusing! Other customers would look a bit puzzled, doubted themselves and then just disregarded it and continued on! Only a few customers honestly noticed they were dealing with a new sales rep and spoke up! Great video to watch when trying to test human attention.
