1 Unit 3 Notes Ch

2 Ch. 8 Learning Learning: A relatively permanent change in behavior due to experience. Classical Conditioning: Pavlov Operant Conditioning: Skinner Modeling: Bandura

3 Associative Learning Classical Conditioning and operant conditioning are also known as associative learning (when two stimuli or a stimuli & response are paired together) Both Classical Conditioning & Operant Conditioning are under the umbrella of Behaviorism

4 Classical Conditioning - Pavlov
UCS (US) – Unconditioned Stimulus UCR (UR) – Unconditioned Response NS – Neutral Stimulus CS – Conditioned Stimulus CR – Conditioned Response UCS creates a UCR NS has no response CS creates a CR

5 CC - Continued Acquisition – When the NS & UCS are paired
Extinction – The CS no longer creates the CR. AKA The diminished responding of the CS no longer signaling the impending the UCS. Spontaneous Recovery – The CS once again creates the CR. AKA the reappearance of a weakened CR after a pause Generalization – When a similar stimulus to the CS creates the CR Discrimination – When only the CS creates the CR Pg

6 CC - Continued Higher Order Conditioning: When a 2nd CS is conditioned to the first CS to create a new CR. Counterconditioning: When a positive stimulus is used to eliminate a negative conditioned response. Aversive Counterconditioning: When a negative stimulus is used to eliminate a negative conditioned response

7 Operant Conditioning - Skinner
Thorndike’s Law of Effect: Rewarded behavior is likely to recur Operant Chamber (Skinner Box): Animal presses a bar or key for food Operant Conditioning is based on reinforcement and punishent

8 Reinforcement & Punishment
Reinforcement increases a behavior Punishment decreases a behavior Positive refers to giving Negative refers to taking

9 Reinforcement & Punishment Cont’d
Positive Reinforcement: Increase by giving Negative Reinforcement: Increase by taking Positive Punishment: Decrease by giving Negative Punishment: Decrease by taking Give Take Increase PR NR Decrease PP NP

10 Shaping; Primary & Secondary Reinforcers
Shaping: Guiding behavior towards successive approximations (step by step towards the desired behavior) Primary Reinforcer: Innate reinforcer that satisfies a biological need Secondary Reinforcer: (Conditioned): Learned and associated with pleasure: Tokens, coupons, or cc connections

11 Reinforcement Schedules
Continuous (Fixed): Patterned Intermittent (Variable): Random Ratio: Based on person Interval: Based on Time

12 Schedules Cont’d Fixed Ratio: Reinforcement occurs after a set number of responses Variable Ratio: Occurs after an unpredictable number of responses Fixed Interval: Occurs after a fixed time period Variable Interval: Occurs randomly during time periods

13 Cognition & Operant Conditioning
Latent Learning: Learning only becomes apparent when there is incentive to demonstrate it (pg. 334) Cognitive Map: A mental representation of a “map”

14 Intrinsic v Extrinsic Motivation
Intrinsic: Desire to perform behavior for one’s own sake Extrinsic: Desire to perform behavior for external reward

15 Observational Learning
Modeling (Bandura) Bobo Doll Experiment: Children more likely to be aggressive after having watched children already be aggressive Mirror Neurons: (Frontal Cortex): Provide neurological basis for observational learning

16 Prosocial Behavior Prosocial behavior: Positive, helpful models who exemplify altruism can prompt this in others

17 Unscramble OBYS SABT TYAR CAPEE CALPE YZRET

18 Learned Helplessness Seligman (LH): Experimented with dogs who were classically conditioned with a bell and shock. Then shocked them on one side of a fence.

19 Ch. 9 - Memory Memory: Ability to store and retrieve information
Flashbulb Memory: A clear memory of an emotionally significant moment or event 3 Stages: Encoding, Storage, Retrieval

20 3 Stages – Information Processing
Encoding: Taking memory in Storage: Holding memory over time Retrieval: Getting information out of memory

21 3 Stages of Memory Sensory: Instantaneous or Subconscious
Short-Term: Holds memory for a brief period of time (5-9 items, up to a few minutes) Working Memory: A newer understanding of short-term memory Long-Term: Relatively permanent and limitless storage of information

22 Encoding Automatic Processing: Absorbing information with no effort
Effortful Processing: Absorbing information that includes attention and effort Rehearsal: Conscious Repetition Spacing Effect: Distributing study over time Serial Position Effect: Remembering first and last items of a list better than the middle

23 Encoding Meanings Visual: Encoding Picture Images
Acoustic: Encoding of sound, particularly words Semantic: Encoding the meaning of words (hit)

24 Visual Encoding Imagery: Using mental pictures to remember
Mnemonics: Memory aids using acronyms Chunking: Organizing into groups or familiar units

25 Sensory & Long Term Memory
Iconic: Subconscious visual memory Echoic: Subconscious auditory memory Long Term Potentiation (LTP): Neural basis for long term memory

26 Implicit & Explicit Memory
Implicit (Non-declarative) (Cerebellum): How to do something Explicit (declarative) (Hippocampus): Facts, Memories, Events Priming: Activation of associations déjà vu: French for already seen. The sense that one has experienced this before Mood Congruent Memory: The tendency to recall information consistent with one’s mood

27 Storage Decay Decay: The forgetting of information
Ebbinghaus’ Retention Curve: New information fades and then levels; the more one studies initially, the less the information fades Proactive interference: Disruptive effect of old information on new information (Old blocks new) Retroactive Interference: Disruptive effect of new information on old information (Old blocks new) Repression: Subconsciously pushing down painful information

28 Memory Construction Misinformation Effect: Incorporating misleading information into memory Source Amnesia (Pg. 384): Attributing a memory to the wrong place or time, including an imagined memory

29 Ch. 10 – Thinking & Language
Cognition: All activities associated with thinking Concept: Mental grouping of similar items Prototype: Best example of a category Algorithm: Methodical, logical method of solving a problem and guaranteeing a solution Heuristic: A simple, rule of thumb strategy -Representative: A prototype, stereotype thought to solve a problem -Availability: Using information in memory to make a decision

30 Obstacles to Problem Solving
Confirmation Bias: A tendency to search for information that confirms our preconceptions Insight: A sudden realization Fixation: An inability to see a problem from a new perspective Mental Set: A tendency to approach a problem in a way that has been successful in the past Functional Fixedness: The tendency to think of things only in their usual functions (uses)

31 Other Cognitive Terms Overconfidence: The tendency to be more confident than correct Framing: The way an issue is posed Belief Bias: The tendency for preexisting beliefs to distort logic Belief Perseverance: Clinging to one’s beliefs in the face of contrary evidence

32 Language Phonemes: Smallest unit of sound with no meaning
Morpheme: Smallest unit of sound with meaning Grammar: System of rules that enable us to communicate Semantics: Set of rules by which we derive meaning Syntax: Rules for combining words and making sense

33 Language Development Stages
Babbling: 4 months-Spontaneous utterances unrelated to language One-Word: Age one – Child speaks in single words Two-Word: Age Two – Child speaks in two words aka Telegraphic: Child speaks mainly using nouns and verbs only to express self. (resembles a telegram)

34 Theories Skinner: Operant Learning – Language is learned primarily through operant principles such as reinforcement & punishment, modeling & imitation. Chomsky: Language Acquisition Device – Language naturally occurs and is to some degree inborn Linguistic Determinism: Language shapes ideas, and language may influence culture and behavior

35 Animal Language Pg. 423 – 428 Do animals communicate with each other?
