69
Inner ear: Cochlea, Basilar membrane, semicircular canals
Cochlea: Snail shaped, fluid filled tube producing nerve impulses in response to sound vibrations

Edward Thorndike
Rewarded behavior is likely to reoccur
80
Primary vs. secondary reinforcement
Primary: Something that is naturally reinforcing (food, warmth, water)
Secondary: Something you have learned to be a reward because it is paired with a primary reinforcement (Good grades = ur fav dinner)
80
Token economy
Individuals are rewarded with tokens, which act as a secondary reinforcer. Tokens can be redeemed for a variety of rewards
80
Positive vs. Negative reinforcement
Positive: A stimulus presented after a response increases a response (getting paid for good grades)
Negative: Removal of an unpleasant stimulus increases a response (taking advil to get rid of a headache)
81
Positive vs Negative punishment
Positive: an undesirable event that follows a behavior (getting spanked)
Negative: When a desirable event ends or is taken away after a behavior (getting phone taken after failing test)
81
Shaping
New behavior is produced by reinforcing responses that are similar to the desired response
81
Continuous reinforcement vs intermittent reinforcement
Continuous:Reinforcement schedule under which all correct responses are reinforced
Intermittent: Some but not all correct responses are reinforced (most effective way)
81
Cognitive learning
Changes in mental processes, rather than changes in behavior alone
81
Schedules of intermittent reinforcement: fixed interval, variable interval, fixed ratio, variable ratio
Fixed interval: rewards a learner after a defined period of time (birthday)
Variable interval: Rewards the learner after an unpredictable amount of time (pop-quiz)
Fixed ratio: Rewards a response after a defined number of correct answers (accumulating points to win a sale)
Variable ratio: Rewards an unpredictable number of correct responses (lottery)
82
Premack principle

85
Atkinson and Shiffrin three stage model of human memory
1. Record information as a fleeting sensory memory
2. Process info into short term memory, where we encode through rehearsal
3. Information can move into long term memory for later retrieval
85
Memories three basic tasks: Encoding, storage, retrieval
Encoding: Putting information into memory
Storage: keeping information in our memory
Retrieval: Getting information out of our memory
86
Rosy retrospection
Recalling the high points while forgetting the mundane
87
3 storage memories: sensory, short term, long term
Sensory: Immediate recording of sensory information in the memory system
Short term: activated memory holds a few items briefly before information is further stored or forgotten
Long term: Relatively permanent and limitless storehouse of the memory system.
87

Peg-word system: requires you to visualize a jingle
Hierarchies: few broad concepts divided and subdivided into narrower concepts
87
Coping mechanisms of short term memory: Chunking + Rehearsal
Chunking: Any memory pattern. Spliting information into chunks allows us to fit more information into the seven available slots of working memory
Rehearsal: Information is repeated to keep it from fading while in short term memory
87
Distributed practice: Spacing effect vs. testing effect
Spacing: Tendency for distributed practice to yield better long-term retention
Testing: testing enhances memory after retreiving
87
Encoding specificity principle vs. Mood-congruent memory
Encoding specificty: The more closely retrieval cues math the way the information was encoded, the better the information will be remembered (taking a test in your designated seat)
Mood-congruent: We tend to selectively remember memories that match our current mood

Procedural: Memory that was not deliberatley learned (muscle memory, automatic processing)
Declarative: Memory had been processed with attention and can be consciously recalled
89
Priming
Introduction of one stimulus influences how people respond to a subsequent stimulus (Prime someone to walk more slowly by having them read words like cautious or leisurely)

-Blocking: Interferene
-Serial position effect: Interference related to the sequence in which material is presented
-Misattribution: memories are retrieved but associated with the wrong time, place, or person
-Suggestibility: Process of memory distortion as the result of deliberate or inadvertent suggestion
Bias: Influence of personal beliefs, attitudes, and experiences on memory
-Persistence: A memory problem where unwanted memories cannot be put out of mind
90

97
Phases of early speech acquisition. receptive, babbling, one-word, two-word, fast mapping
Receptive: Recognizing when sounds are broken into words, sounds associate with facial movements
Babbling: Spontaneously utters various sounds
One-word: Child speaks mostly in single words
Two-word: Child speaks mostly in two-word statements
Fast mapping: toddlers begin to use context and what the learned others say in order to learn the meaning of new words
