Psychology 101 Week 4 Note: In this chapter we skipped around quite a bit and had some in depth discussions over a couple of different topics. This is the main coverage of what he said would be on the test. How do people filter things and what does that mean? It’s how different people perceive things, how we filter information is based on a lot of different things. 1) Experiences 2) Different People 3) Environment 4) Nature vs Nurture A very good example was how a deaf person perceives a concert. While we hear the music how do they interpret it? Someone who cannot hear the music may be more aware of their surroundings because they aren’t focused on the music but how they feel the music is through vibrations. Their other senses take over and strengthen. Next in class we watched The Human Eyeborg: Neil Haribisson at Ted Gateway it was a very interesting piece about a man who was color blind and made a device that made it so he could hear color. Transduction- Transforming signals into neural impulses. Sensory Adaptation- decreased responsiveness to stimuli due to constant stimulation. Cocktail Part Phenomenon: the ability to focus one’s listening attention and single talker among a mixture of conversations, noises, and ignoring other conversations. Energy vs. chemical senses Vision- most dominant sense, is always taking place in all senses. Visually capturing everything. Trichromatic Theory: color perception is produced by three types of cone receptors in the retina that are particularly sensitive to different, but overlapping, ranges of wavelengths. Opponent Processing Theory: theory that sensory receptors come in pairs. Red/Green, Blue/Yellow Hearing- we listen in waves. We were told that we need to know the layout of the middle ear and the inner ear, and its’ functions. The Middle Ear consists of the eardrum which vibrates in response to sound, the hammer, anvil, and stirrup which are intricately connected small bones. When they vibrate to receive sound waves and they then transmit them to a fluid filled inner ear. The Inner Ear is made up of the cochlea, a tubular, fluid-filled structure that is coiled up like a snail. The basilar membrane lines the inner wall of the cochlea, and cilia line the basilar membrane. Perception- what you see sometimes knowingly other times unknowingly. We watched a video called, A toy’s story, How to Control A Nation. The video is about how a man can manipulate a woman into buying something and she doesn’t even know it. PWA Perception- Top down processing, from the brain going down the nerves. Bottom Up Processing, going from the base of the nerves up to the brain. Signal Detection Theory- absolute thresholds are not really absolute Things like motivation or physical state can effect what we sense. -False Positives -False Negative Figure Ground Relationship- our first peceptional decision is what the image is and next to it *Subliminal Messages- when the brain recognizes something but we don’t like adds that secretly tell you to buy a product or hint at something.
