PSY 360 WEEK 2 DQ 1 What are the different types of perception How do the different types of perception come together to determine cognitive functioning Is it possible for a person to function cognitively solely on one type of perception Explain why or why not Perception is defined as the related process by which the brain selects organizes and interprets sensations Sensations are immediate experiences of qualities red hot bright whereas perceptions are experiences of objects or events that appear to have form order or meaning Kowalski amp Westen 2005 p 102 Types of perception would include internal perception depth perception color perceptions speech perception figure ground perception positive and negative afterimages illusion size and motion perception and visual contrast I am sure there are more but this is all I can think of All of these perceptions work together when a particular combination of sensory events becomes associated with specific consequences when this raw information takes on meaning I think a person s perception of the world and stimulus around them is different for individual people If someone is colorblind his or her perception of different colors like red or green is different or completely absent They may look at a field and see or perceive it in a very different way than I would If a person is clinically depressed or mentally ill their perceptual world will be much different from mine To determine all of these things researches and scientist need to have a firm understanding of all cognitive abilities and limitations Personally I do not think it is possible for a person to function cognitively on any one type of perception solely that is For example If all I had was depth perception but could not determine the size motion or distance of objects around me I would not be able to correctly organize and interpret sensations around me Essentially I think it would make for a more confusion Perceptions vary because they are also in uenced by our experiences expectations and needs Having to rely on just one would not work in my opinion Furthermore I think it is easy to get sense and perception confused Yes we all know that we can live without our primary senses of hearing taste sight smell touch However to live solely on one cognitive perceptual process would be almost impossible Hello Renny With reviewing perception this is noted by Willingham 2007 as the set of process by which we recognize organize and make PSY 360 WEEK 2 DQ 1 sense of stimuli in our environment which can be viewed from either of two basic theoretical approaches bottomup or top down With reviewing these two choose either bottom up or topdown processing and make an argument that whichever you chose is more important than the other Use specific examples of situations to illustrate your point Dametrius Byno Ph D GCDF Faculty University of Phoenix Dr Byno Thank you Honestly I can t say that either view of bottom up or top down theory is more important than the other Maybe you could solidify that for me But from what I understand when an interpretation emerges from the data this is called datadriven or bottomup processing Perception must be largely datadriven because it re ects mare accurately For instance you want the interpretation of a scene to be determined mostly by information from the senses not by your expectations Whereas schemadriven or topdown processing is a pattern formed earlier on in our experiences From what I am understanding there are many circumstances that our expectations or knowledge will in uence our perceptions In general top down processing information processing based on previous knowledge or schemata allows us to make inferences to quotknowquot or quotperceivequot more than is shown in the data Looking at this picture you can either see 1 animals or 2 faces Depending on whether they saw animals or faces in previous slides you either see I a rat or 2 a man wearing glasses This is a form of top down processing in which a schema in uences interpretation of the data
