Title: Operant Conditioning


1
Operant Conditioning
  • Action results in consequence
  • Decision
  • B.F. Skinner
  • Three term contingency
  • Stimulus - response - outcome

2
Outcomes
  • Positive or negative
  • Reinforcement or punishment

3
Differences from Classical
  • Usually assumed to be under conscious control
  • Operant conditioned after the behaviour
  • Outcome feeds back to alter response

4
Probabilities
  • Hierarchy of behaviours (actions)
  • Probability
  • Operant conditioning changes events and/or
    consequences
  • Results in adjustment of probability hierarchy

5
Trial and Error
  • Thorndike
  • Puzzle boxes and cats
  • Law of effect

6
Discriminative Stimulus
  • Elicits learned behaviour
  • Indicates outcome
  • Reward/non-reward condition

7
Shaping
  • Directed learning
  • Behavioural outcome more certain
  • Select a specific response to occur in a specific
    way
  • Gradual process
  • Chaining
  • Forward and backward

8
Reinforcement Schedules
  • Fixed ratio
  • Fixed interval
  • Variable ratio
  • Variable interval

9
Reinforcement Consistency
  • Continuous schedules
  • Intermittent schedules
  • Response-reinforcer?
  • Technically, only FR-1 is continuous
  • Systematic reinforcer
  • Any fixed schedule (FR or FI)

10
Extinction
  • Response - outcome pattern disrupted
  • Easiest for
  • Continuous reinforcement/punishment
  • Low schedules
  • Variable ratio schedules hardest to extinguish

11
Reinforcers
  • Primary
  • Secondary
  • Speed of learning
  • Extinction
  • Money

12
Delay
  • Immediate reinforcement
  • Delayed reinforcement
  • Generally, delayed harder to condition
  • Difference with well conditioned system

13
Changing Schedules
  • Cost of response
  • Contingency
  • Rate of reinforcement
  • Modification
  • Decrease
  • Increase
  • Delay

14
Applications
  • Discriminative stimulus
  • Blue-light special, coloured sale tags, logos
    (if previous positive experience with product)
  • Christmas music in October
  • Positive reinforcement
  • Give-aways, purchase points, Canadian Tire money,
    parking lot barbeques
  • Negative reinforcement
  • Purchase to avoid pushy sales pitch

15
  • VR schedule
  • Lotteries, door prizes, etc.
  • Shaping
  • Free trial periods, leading signs/displays (get
    person into store area)
  • Punishment
  • Unusual in advertising/marketing
  • Commercials showing customer who suffers from not
    using product (observational learning)

16
Ecological Design
  • Structuring the environment
  • Facilitation of particular behaviour(s)
  • Increase/decrease probability of response
  • Store layout, purchase locations, noises, odors,
    lighting
  • A type of shaping of a response

17
Behaviour Modification
  • Application of operant theory to change behaviour
  • Primary application of operant principles
  • Skinners behaviour analyst techniques

18
Behav. Mod. in Marketing
  • Role of marketing as influencing, modifying, and
    controlling consumer behaviour to achieve
    purchasing objectives
  • An applied field
  • Not aimed at developing theory, but applying
    theory
  • Observable behaviour
  • No inferred behavioural constructs

19
Economic Psychology
  • Integration of psychology and economic analysis
  • Marketing
  • Not a discipline
  • An application area for the social sciences and
    other disciplines
  • EcPsyc offers detailed analysis of consumer-firm
    interactions

20
Behavioural Perspective Model
  • Gordon R. Foxall
  • Operant behaviourist paradigm
  • Modern marketing firms
  • Embedded in networks of marketing relationships
  • Extra-firm environment (e.g., consumers) drive
    marketing behaviour
  • Reinforcement/punishment shift firms behaviour
  • Applies also to behaviour of individuals
    comprising the firm (e.g., employees, owners,
    shareholders, etc.)

21
A Firms Purpose
  • To make marketing relationships more economic
  • Production and selling are independent of firms
  • Dont need firms to do these
  • Creation and maintenance of marketing is what
    firms do

22
Uhm So?
  • Operant conditioning theory and firms
  • Economic behaviour is instrumentally conditioned
  • Behaviour that operates on the environment to
    produce consequences changes the future rates of
    behaviour
  • Reinforcement/punishment shifts economic (market)
    factors

23
Consumer Behaviour
  • Economic purchasing and consumption activities
  • Basic three-term contingency applies
  • Stimulus - response - outcome
  • Plus, consumer behavioural setting and learning
    history

24
Behav. Persp. Model and Consumers Choice
  • Consumer choice reduces aversive consequences of
    facing multiple equivalent options

25
Model
26
Marketing Management in BPM
  • Influence two factors
  • Consumer behaviour settings
  • Social, physical, temporal, and regulatory
    discriminative stimuli
  • Utilitarian and information reinforcers
  • Actual outcome and knowledge gained

27
Managing Reinforcers
  • Three ways
  • Enhancing effectiveness of reinforcers
  • Controlling the schedules of reinforcer delivery
  • Increasing the quantity or quality of reinforcers

28
Complexities
  • Multiple systems operating simultaneously
  • Is operant conditioning separable from classical?
  • Do stimuli fulfill role of CS, SD, or both?

29
Role of Operant Reinforcer in Classical
Conditioning
  • In classical conditioning
  • US presented regardless of CR
  • Defining feature
  • But, operant reinforcement can slip in
  • Operant reinforcement via
  • 1. Reinforcing CR directly
  • e.g., food (US) coming after CR
  • 2. CR increases value of US
  • e.g., salivation (CR) makes swallowing food (US)
    easier

30
Omission Control Procedure
  • US presentation depends on occurrence of CR
  • CS presented if no CR, US follows
  • CS presented if CR, no US follows
  • Therefore, US cant operantly reinforce CR

31
Omission Control
32
Conclusion
  • Can have classical conditioning without operant
    reinforcement
  • But what about classical conditioning in operant
    conditioning?

33
Associative Structure in Operant Conditioning
  • Basic form of association
  • S-R
  • S-O
  • Pavlovian processes
  • Can keep instrumental reinforcement out of
    classical conditioning, but not vise versa

Outcome
Stimulus
Instrumental response
34
S-R, S-O, rg-sg
  • Thorndikes Law of Effect
  • Focus on S-R association
  • Hull and Spence
  • Law of Effect plus a classical conditioning
    process

35
  • Classical conditioning process --gt motivation
  • Expectancy of reinforcement motivates operant
    response
  • Classical conditioning via stimulus substitution
  • S acquires properties of O
  • rg fractional anticipatory goal response
  • Response leads to feedback
  • sg sensory feedback
  • So classical conditioning develops during operant
    conditioning
  • rg-sg constitute expectancy of reward

36
Fractional Anticipatory Goal Response
  • SD influences rg-sg through sensory
    substitution-like process
  • Classical conditioning
  • Elicits expectancy of reward

37
Prediction
  • According to rg-sg
  • CR occurs before operant response
  • But, not always true
  • e.g., lever pressing and salivation
  • CR should occur before operant, but it doesnt

38
Central Emotional State
  • Classical conditioning in operant conditioning
  • Not for learning response
  • For CES (Central Emotional State)
  • CES --gt motivation, mood

39
Modern Two-Process Theory
  • Classical in operant conditioning
  • Neutral stimulus --gt elicit motivation (CES)
  • CES elicited by CS corresponds to US
  • CES a characteristic of CNS mood
  • CES doesnt produce only one response
  • e.g., anger --gt multiple responses
  • CES conditioned during ordinary operant training
  • CES conditioned to situational cues or
    discriminative stimulus
  • CES motivates operant behaviour

40
Prediction
  • Rate of instrumental response will be modified by
    presentation of CS
  • Consider
  • In operant conditioning, CES develops to motivate
    operant response
  • CS from classical conditioning also elicits CES
  • Therefore, giving CS during operant conditioning
    will alter CES that motivates/maintains operant
    response

41
Conditioned Emotional Response
  • Suppression ratio
  • CES elicited by CS --gt decrease response

42
Explicit Predictions
  • Emotional states

43
  • Behavioural predictions

Aversive US Instrumental schedule CS(fear)
CS-(relief) Positive reinforcement decrease incr
ease Negative reinforcement increase decrease
