25
Cones
Concentrated near the retina, function in daylight and well-lit conditions and detect fine detail and colors
26
Rods
Detect black, white, and grey. Used when cones don't respond
27
Blind Spot
The point where the optic nerve leaves the eye, creates a blind spot because there are no receptor cells there
28
Lens
The structure behind the pupil that changes shape to help focus images on the retina
29
Context effect
Influence of surrounding objects, events, or information that change an organisms perception of a stimulus
30
Semicircular Canals
Three looped tubular channels in the inner ear that detect movements of the head and are essential for maintaining balance
31
Cochlea
Fluid-filled bone in the inner ear, sound waves trigger nerve impulses
32
Conduction Deafness
Hearing loss caused by damage to the system that conducts sound waves to the cochlea
33
Shape constancty
A type of perceptual constancy where an object is perceived as having the same shape despite being viewed from different angles
34
Cognitive Map
A mental representation of the layout of an environment
35
Shaping
Operant conditioning procedure where reinforces guide behavior closer and closer to the desired behavior
36
Mirror Neurons
Frontal lobe neurons that scientists believe fire while performing actions or observing others doing so. Enable imitation and empathy
37
Unconditioned stimulus
Stimulus that naturally triggers a response (ex. food)
38
Unconditioned response
An unlearned, naturally occurring response (ex. saliva)
39
Conditioned stimulus
An originally irrelevant stimulus that, after association with an unconditioned stimulus, triggers a conditioned response (ex. bell)
40
Conditioned response
A learned response to a previously neutral stimulus (ex. saliva because of bell)
41
Social Learning Theory
The theory that we learn social behavior by observing and imitating others
42
Operant Conditioning
A type of learning in which behavior is strengthened through a reinforcer and diminished by a punisher
43
Positive Punishment
Adding a negative stimulus in order to decrease behavior (ex. pain)
44
Negative Punishment
Taking away a rewarding stimulus in order to decrease behavior (ex. taking away a kid's iPad)
45
Positive Reinforcement
Increasing behaviors by adding a pleasurable stimulus (ex. giving candy)
46
Negative Reinforcement
Increasing behaviors by taking away negative stimuli (ex. taking away bedtime)
47
Inductive Reasoning
A method of drawing conclusions by making broad conclusions based off specific observations (Bottom-up)
48
Deductive Reasoning
A method of drawing conclusions that is based on multiple premises (Top-down)
49
Prototype
A mental image or best example of a category
50
Procedural memories
The memory system that helps us remember how to do things like riding a bike, typing on a keyboard, or solving a math problem. It helps us remember the steps and techniques needed to perform a task.
51
Aptitude Test
Predicts a person's future performance
52
Achievement Test
Designed to test what a person has learned
53
Algorithm
A methodical, logical rule that guarantees solving a particular problem
54
Heuristic
A simple thinking strategy that allows us to make judgements and solve problems efficiently, faster but more error prone than algorithms
55
Phonemes
The smallest distinctive sound unit
56
Morphemes
The smallest unit that carries meaning
57
Hindsight bias
The tendency to believe, after learning an outcome, that one would have foreseen it
58
Functional Fixedness
The inability to use an object for something other that how it is usually used
59
Retroactive Interference
When new information blocks the recall of old information
60
Proactive Interference
When old information blocks new information
61
Savant Syndrome
A condition where a person otherwise limited in mental ability has an exceptional specific skill
