Term
Sensation
Definition
The sensory receptors are stimulated by the environment and sends information to the brain
Term
Perception
Definition
The brain processes and organizes sensory information into something meaningful
Term
Transduction
Definition
Process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation.
Term
Absolute Threshold
Definition
Minimum intensity of stimulation needed to detect a stimulus half the time
Term
Difference Threshold
Definition
Minimum amount of change required to detect a difference half the time
Term
Sensory Adaptation
Definition
In order to detect novelty around us, our senses tune out constant stimuli
Term
Selective attention
Definition
Brain has ability to focus on one thing
Term
Cocktail party phenomenom
Definition
Can focus on one conversation while several are occuring
Term
Selective attention
Definition
What our brain does not focus our attention on

Term
Color Blindness
Definition
Actually not blindness, lack cone responsible for a given color
Term
Opponet Process Theory
Definition

Opposing retinal processes allow for color vision,

Some retinal cells are excited by one wavelength of cone but is habited by another

Term
Gestalt principles
Definition
We have he tendency to integrate pieces of information into a meaningful whole
Term
Proximity
Definition
The closer 2 figures are, the more likely they will be grouped together as one object

Term
Motion Parallax
Definition
The relative movements of objects at varying distances from the observer
Term
Binocular Disparity
Definition
Distance between images on retina of both eyes, how eyes see depth
Term
Perceptual Constancy
Definition
Brains ability to see objects as constant despite sensory date that leads to misperceptions
Term
Ames Room
Definition
An illusion that makes us think the far corner is the same distance as the near corner, Making onjects look different sizes
Term
Ponzo Illusion
Definition
uses depth cues such as converging lines ot suggest distance ina  visual image
Term
Muller-lyer Illusion
Definition
Lines look different lengths depending on the way the arrowheads point
Term
Prosopagnosia
Definition
Inability to recognize faces
Term
Learning
Definition
Modification of behavior & understanding based on experiences
Term
Classical Conditioning
Definition
A learned response that occurs when a neutral object is associatd with a reflexive response
Term
Ivan Pavlov
Definition
Physiologist studying salvation in dogs
Term
Neutral Stimuli
Definition
A stimulus that shouldnt elicit a response
Term
Classical Conditioning
Definition
A stimulus that elicits a response without any prior learning
Term
Unconditioned Response
Definition
A response that doesnt have to be learned
Term
Conditioned Stimulus
Definition
A stimulus that elicits a response after learnign has occured
Term
Conditioned Response
Definition
A response that has been learned
Term
John Watson
Definition
1919, believed phobias could be explained by classical conditioning
Term
operate Conditioning
Definition
Consequences of an action determine the likelihood it will be performed in the future
Term

Term
Law of effect
Definition
Behaviors that result in positive effects are more likely to occur again than behaviors that lead to negative effects
Term
B.F. Skinner
Definition
Law of efffect not scientific enough
Term
Reinforcers
Definition
Event following a behavior that increases the likelihood the behavior will be repeated
Term
Shaping
Definition
reinforcing behaviors that are increasingly similar to the desired behaviors
Term
Extinction
Definition
decrease in behavior when a reinforcer or a punishment no longer occurs
Term
Reinstatement
Definition
Reappearance of behavior following a priming of reinforcement
Term
Spontaneous Recovering
Definition
Following a period of time after extinction, the behavior spontaneously reappears
Term
Positive Reinforcement
Definition
Increases probability of behavior being repeated following administration of a pleasureable stimulus
Term
Negative Reinforcement
Definition
Increases probability of behavior being repeated following removal of an aversive stimulus
Term
Sensory Memory
Definition
1/3 second, What did I just Say?
Term
Short-term memory
Definition
Limited capacity, holds info in awareness for a short period of time
Term
Memory Span
Definition
How many items one can remember in short term memory
Term
Chunking
Definition
Organizing information into meaningful units
Term
Mnemonic
Definition
Connects information to existing memory strangths such as imagery or structure
Term
Hierarchical/Categorical
Definition
Branching/nested set of categories & sub categories
Term
Working memory
Definition
Active processing that allows one to use different types of information
Term
Visuao spatial Sketchpad
Definition
Visual info & an objects features
Term
Auditory Rehearsal
Definition
encodes auditory info such as reading & speaking
Term
Central Executive
Definition
Coordinate information, encodes sensory info & sends to long-term memory as well as retrieving info from long-term memory
Term
Long-term memory
