Psych Ch 5

TermDescription
Sensation the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
Perception process of selecting, organizing, and interpreting our sensations
Top down processing relating your stored knowledge to the sensory input (prosopagnasia)
Psychophysics the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them
Bottom Up processing analysis that begins with the sense receptors and works up to the brian's integration of sensory info
absolute threshold the minimum stimulation needed to detect a particular stimulus 50 percent of the time
Signal detection Theory predicts how and when we detect the presence of a faint stiumulus (signal) amid background stimulation (noise). Assumes there is no single abs. thresh and that detection depends partly on a person's experience, expectations, motivation, and level of fatig
Subliminal below ones abs thresh for concious awareness
Y or N on subliminal messages? May be affected, process info w/out being aware. Sub sensatin but not PERSUASION
Difference Threshold aka JND the minimum difference a person can detect between any two stimuli; increases with magnitude of stim
Weber's Law For the average person to perceive a diff, the diff must be in proportion 8% lights, 2% weights, .3% freq
Sensory adaptation diminished sensitivity as a consequence of an unchanging stimulus (our nerve cells start to fire less frequently)
Sensory transduction sensory systems convert stimulus energy into neural messages
Wavelength the distance from one wave peak to the next
hue the color we experience
intensity the amount of energy in light waves (determined by lights amplitude or height)
Pupil where light enters
iris regulates amt of light entering eye, colored portion of the eye, controls size of pupil opening
Lens Behind pupil that changed shape to focus images on the retina
accomodation the process by which the eye's lens changes shape to focus the image of near objects on the retina
Acuity sharpness of vision
nearsightedness nearby objects are seen more clearly than distant objects bc the lens focuses the image of distant objects in front of the retina
farsightedness faraway objects are seen more clearly than near objects bc the image of near objects is focused behind the retina
