Chapter 6- Perception Limitations of perception: we can hear and smell things but we cannot locate where it is o Our perspective is limited to what we think and it the only one we have o If we could see P.O.V from another person Vision received the most attention from psychologist bc most important to humans Perception: process which we recognize what is represented by the information provided by our sense organs gives unity and coherence to this input o Rapid, automatic, unconscious process Example: we dont just see the cylinder, then the glass cup; we just perceive it as the glass. Distinction btw sensation and perception is hard to distinguish Brain Mechanisms of Visual Perception Visual perception= hierarchy of information processing * info that is sent from the eyes to the thalamus is then sent to the primary visual cortex, located in the middle of the occipital lobes, back of the brain THE PRIMARY VISUAL CORTEX Research in the thalamus and primary visual cortex lead to knowledge of visual analysis HUBLE & WEISEL: insert microelectrodes (small wires) in cats and monkeys; it detects axn potentials in certain areas of the brain to see which gave most response. Conclusion: geography of visual field is retained in the primary visual cortex like a map Module: block of tissue approx 0.5x 0.7mm each w 150 000 neuron that receive info from the same group of receptor cells in retina = about 2500 modules in primary visual cortex o Bunch of tiles working with one another processing the same information Receptive field: part of visual field which what we see (visual stimuli) will produce different firing rates of a particular neuron o Example: some circuits detect presence of lines pass through based on the angle of the line o Others detect mvment of lines and direction of mvments o Others detect lines colours Neurons respond most when line is at 50 degrees The different degrees that images are on the retina; Respond less at 70 or 30 degrees when the line is passing through receptive field Info from primary is sent to 2 levels parietal (visual association cortex) and temporal area (2 level of association in the cortex) www.notesolution.com
