Cognitive Psych Flashcards
Introspection
People report their thinking as they perform a task
Experimental Cognitive Psych
Lab experiments with controls and participants
Cognitive Neuroscience
Study how the brain reacts to certain tasks or stimuli using brain scanning
Cognitive Neuropsych
Study brain scans of people with brain damage
Computational Cognitive Science
Using computer processes to understand the brain
Object Recognition
Match image with internal representation
Feature Theory
Match image features with features in memory
Template Matching Theory
Compare incoming stimuli to previously known stimuli/2D picture
Recognition By Components (RBC)
Rely on goons to recognize objects
Holistic Processing
Recognize faces as a whole
Prosopagnosia
Inability to recognize faces
Capgras Syndrome
Delusion in which you believe family members have been replaced by imposters
Imagery
Mental representation of stimuli not physically there
Propositional Coding
We think about specific characteristics
Analog Coding
We pull up mental images
Evidence
Mental rotation, image scanning, size scaling, selective interference, neurophysiology
Subliminal Perception
Perceiving information below your conscious awareness
Deja Vu
Feeling of familiarity of experiences, but knowing you haven’t (Associative vs. Biological)
Freud
Believed that deja vu was caused by repressed memories or desires
Divided Attention
States that deja vu is caused by background info that is being absorbed whole you are consciously aware of other things
Hologram Theory
States that deja vu is the current/new situation that shares some common components as the old one (enough to feel familiar but not enough to be a memory)
Delayed Vision
States that deja vu is visual info that travels through different paths, one piece of info is delayed and when it arrives the brain assumes it has already experienced it
False Memories
States that deja vu is something that activates a memory from a movie or something similar and then is interpreted as an actual memory
Blindsight
Visual cortex damage, no conscious visual perception, but able to perform visual tasks well
Conscious Will
Rubber hand illusion, body swap illusion, out of body experiences
Ideomotor Effect
No conscious awareness of your body movements (Ouija board)
Soon (2008,2013)
Found a 5-7 second gap between unconscious brain activity and conscious decision
Visual Attention
Feature search=parallel processing (all at once)
Conjunction Search
Serial processing (one at a time)
Spatial Attention
Attention as a “spotlight”
Change Blindness
Change in surroundings that go unnoticed by the observer, failure to recognize
Auditory
Dichotic listening/selective listening
Divided Attention
Influences: Similarity of tasks and practice
Studies: All texts while driving impair attention
Atkinson and Shriffon Model of Memory
Sensory store-> STM-> LTM
Sensory Store
High capacity, purely physical, brief duration (seconds)
STM
Limited capacity (7+/-2), acoustic coding, 15-30 second duration
LTM
Large capacity, semantic coding, long and permanent duration
Baddley and Hitch
Working Memory Model
Phonological Loop
Verbal, auditory info. Word length effects, articulatory suppression, irrelevant speech effect
Visuospatial Sketchpad
Visual, location info. Grid studies, image complexity, imagery studies
