Section 1

Question Answer
gestalt psychologyemphasis on role of organized wholes in perception and other psych processes
similaritygroup like figures, by color or organization
proximitycloseness of two figures, closer together>we group
good continuationperceive contours in a way that alters their direction as little as possible
subjective contourspercieved contours that do not exist in reality
revrsible figurevisual pattern that easily allows more more than one interpretation
visual searchparticipant determine whether a specified target is present w/in a feild of stimuli
feature netmodel of pattern recognition involving a network of detectors & having feature detectors as networks starting point
geonssimple geo figures that can be combines to create other figures
magno cellsganglion cells, bc sensitive to brightness changes, good at perceiving motion and depth
parvo cellsganglion cells, bc sensitivity to hue, ,good to perceive color and form
"what system"visual pathway from visual cortex to temperal lobe that identifies objects
"where system"VP from VC ro PL involved in locating objects in space and coordinating movements
binding problemprob brain has recombining elements of a stimulus, given the fact that these elements are initially analyzed seperately by diff neural systems
perceptual constancyaccurate perception of certain attributes of a distal object, such as shape size, brightness, despite changes in proximal stimulus caused by variations in viewing circumstances
unconscious inferenceexplain size constancy
depth cuessources of info that signal distance from observer to distal stimulus
binocular disparitydepth cue based on differences between two eyes views of world
monocular depth cuesindicate distance even if stimulus is viewed with one eye
pictorial cuespatterns that can be represented on a flat surface in order to create a sense of a 3D object or scene
interpositionmonocular cue to distance that relies on fact that objects farther away are blocked from view by closer objects
linear perspectiveparallel lines converge as they get farther away (distance cue)
motion parallax(depth cue) as observer moves, retinal images of nearby objects move more rapidly than do far away
motion detectors cells that are sensitive to motion across retina
apparent movementturn a light on, turn it off, turn another one one, looks like it jumped
induced motionperceived movement of stationary stimulus, usually caused by movement of a surrounding framework or nearby objects
correspondence problemas view changes, perceptual task of determining which aspect of the current view corresponding to which aspects of the view seen a moment ago
illusory conjunctionsee a green X and red O, actually green O and red X
primingdetector of NS prepared for upcoming input, making it easier to recognize

Section 2

Question Answer
consciousnessmoment by moment awareness of ourselves
introspectionlooking w/in
cog unconsciousnessmental support preocess that make up perception, memory, and thinking possible (unaware)
blindsightblind ppl guessing stuff
mind body probunderstanding how they influence eachother
neutral correlates of consciousnessspecific brain states that correlate to content of someones conscious experience
global workplace consciousnessneutral basis of consciousness. proposal: workplace neurons give rise to consciousness by allowing us to link stimuli or ideas in dynamic, coherent representations
alpha rhythmpattern of reg pulses, 8-12, relaxed, eyes closed
beta rhythmactively thinking about topic
delta rhythmslow wave sleep pattern
slow wave sleepstage 3, slow rolling eye movement, slowed heart and breathing
REMsimilar to wakefulness, speeded heart rate&resp, near paralysis, highly visual dreams
activation sythesis hypdreams=byproduct of sleeping brain
