2) Cognitive Psychology: Perception and Object Recognition

hollistic

Patient C.K. had a head injury in an auto accident and was considered a "_____" perceiver. He could perceive whole faces/ overall shapes, but cannot recognize the parts.

sensation

A _____ is the elementary components of an experience. Sight, taste, change in temperature

Mailbox Task

In the _____ ____, D.F. could not ID orientation of a mail slot. But she could successfully post a letter!

split-brain

Joe was a _____-_____ patient who had his corpus callosum split in half. He was able to project shapes to each visual filed and draw simultaneously. Words that were presented to the left visual field with processed in the right hemisphere and he could not read them. He also perceived the same picture as a face or fruit depending on which visual field he saw the picture in.

margaret thatcher illusion

The _____ _____ _____ is when we see inverted faces and dont seem to notice the mixed up features but when we look at upright faces we immediately notice how bizarre it looks. This suggests that we naturally process faces in an upright position.

parietal, temporal

The dorsal pathway is located in the _______ lobe of the brain. "Where" or "How". The ventral pathway is located in the _______ lobe. "What"

ventral, dorsal

There are two visual system pathways which are the _____ pathway (identifying objects, conscious visual experiences) and the _____ pathway (locating objects in space, "vision for action")

Change blindness

_____ ____ is when someone thinks they noticed something changed but did not acknowledge it because of the context and setting. It would be weird and would need cognitive energy to recognize the change

retinal disparity

_____ _____ is when there is a difference in location of the image in each eye

depth perception

_____ ______ is important for monocular depth cues. Only requires one eye. And binocular depth cues. Depends on the comparison between both eyes.

monocular

_____ cues are important for seeing things that are far away, relative size, overlap, linear perspective, shading, haze, ect.

perception

_____ is a collection of processes that arrive at a meaningful interpretation of sensations

prosopagnosia

_____ is brain damage that results in a selective, specific deficit in the ability to recognize faces. Often occurs with deficit in recognizing other objects.

agnosia

_____ is when damage to the brain produces a deficit in visual object recognition. Not a memory deficit (Can draw pictures from memory). Example: Dee Fletcher (D.F.)- carbon monoxide poisoning left her with severe inability to identify objects. Could not copy objects, but could draw them from memory.

top-down processing

_____-_____ _____ is conceptually driven and identifies an object with the help of context, previous knowledge, and/or expectations. GOAL DRIVEN. Processing that originates in the brain, at the top of the perceptual system. (perceiving objects, hearing words in a sentence, experiencing pain). Example, "THE CAT" being reading as the cat even if the A and the H are the same. Context is important!!

optic ataxia

______ _____ is damage to the dorsal pathway. Patient named Ruth Vickers had this. Difficulty in reaching for and grasping objects. But preserved the ability to recognize and describe objects.

convergence

______ is the extent to which eyes move inward and is only good for close up sight

bottom-up processing

_______-___ ________ is perceptually driven and identifies an object by analyzing and assembling it component features. DATA DRIVEN. Starts at the bottom, or beginning, of the system when environmental energy stimulate the receptors
