Title: LEARNING


1
LEARNING
  • Resource Material By
  • Prof Namita Gupta

2
What Is Learning?
3
Learning
  • Any relatively permanent change in behavior that
    occurs as a result of experience
  • Learning components

4
Theories of Learning
  • Classical Conditioning
  • A type of conditioning in which an individual
    responds to some stimulus that would not
    ordinarily produce such a response.
  • Operant Conditioning Reinforcement theory
  • A type of conditioning in which desired voluntary
    behavior leads to a reward or prevents a
    punishment.
  • Social-Learning Theory
  • People can learn through
  • observation and direct experience.

Classical Conditioning- its historyPavlovs
Dogs-Digestive reflexes and salivation, Psychic
secretion
Whats this about LEARNING?

Classical Conditioning

Stimulus
  • 1-Neutral Stimulus-Bell-Does not normally
    elicit a
  • response or reflex action by itself
  • A bell ringing,
  • 2-Unconditioned StimulusFood
  • Always elicits a reflex action an
    unconditioned
  • response
  • Food,
  • 3-Unconditioned ResponseSalivation
  • A response to an unconditioned stimulus
  • naturally occurring
  • Salivation at smell of food,

8
STIMULUS _Cont
  • After learning took place
  • 4-Conditioned StimulusBell
  • The stimulus that was originally neutral
    becomes conditioned after it has been paired
    with the unconditioned stimulus. Will elicit
    the unconditioned response by itself
  • 5-Conditioned Response
  • The original unconditioned response
    becomes conditioned after it has been elicited
    by the neutral stimulus

9
Operant Conditioning
  • Operant conditioning takes place all around us in
    our homes, as well as the workplace.
  • Parents use rewards, or operant conditioning to
    get their children to do their homework.
  • Type of learning in which behavior is
  • strengthened if followed by reinforcement or
  • diminished if followed by punishment

10
HISTORY OF OPERANT CONDITIONING
  • Famous behavioral psychologist, followed
    Thorndike in using animals to investigate
    operant conditioning.
  • Skinner Box constructed a box with a lever
    inside- when an animal pressed the lever, a food
    pellet fell out of a feeder into the box, Skinner
    wanted to see if rats placed in the box could
    learn to press the lever in order to receive the
    food.

11
SKINNERs Experiment
  • Behaviorism -The attempt to understand observable
    activity in terms of observable stimuli and
    observable responses
  • Early Operant Conditioning- learning in which
    voluntary response are controlled by consequences
  • by John B. Watson (1913),B.F. Skinner
    (1938)-used rats

13
Reinforcement Theory
It used the fundamental of operant theory in
practical practice
  • Emphasizes that people are motivated to perfor or
    avoid certain behaviors because of past outcomes
    that have resulted from those behaviors
  • Response consequences that increase likelihood of
    responding in a similar way again.
  • positive reinforcement
  • negative reinforcement
  • Punishment
  • extinction

14
Shaping A Managerial Tool
  • Systematically reinforcing each successive step
    that moves an individual closer to the desired
    response.
  • Four Methods of Shaping Behavior
  • Positive reinforcement
  • Providing a reward for a desired behavior
    (learning)
  • Negative reinforcement
  • Removing an unpleasant consequence when the
    desired behavior occurs (learning)
  • Punishment
  • Applying an undesirable condition to eliminate an
    undesirable behavior (unlearning)
  • Extinction
  • Withholding reinforcement of a behavior to cause
    its cessation (unlearning)

15
Reinforcement- Consequences of behaviour
  • Positive reinforcement An events presentation
    following a response increases the future
    probability of that response. Ex-Praising for a
    good sales performance by the boss.
  • Negative reinforcement An events removal
    following a response increases the future
    probability of that response. Ex Reduction or
    elimination of the future supervision/ Scolding
    by the boss after responsible work performances
    from employees.
  • Punishment- The process by which a stimulus or
    event weakens or reduces the probability of the
    response that it follows. Ex-Beating to a thief
    after being caught by the police.
  • Extinction-Making one forget the present
    response. Ex- Lack of attention paid by
    colleagues on another salesman who makes jokes
    over customers

16
Schedule of Reinforcement-when how
17
Schedules of Reinforcement
  • Two Major Types
  • Continuous Reinforcement- A desired behavior is
    reinforced each time it is demonstrated- EX 1 to
    1 ratio, a prize every time
  • Intermittent Reinforcement-A desired behavior is
    reinforced often enough to make the behavior
    worth repeating but not every time it is
    demonstrated or in Multiple frequencies
  • Ex- Ratio
  • fixed 1prize for each race
  • Variable maybe a prize, maybe not!
  • Interval
  • fixed announced examination after every 1 month
  • variable pop quiz any time

18
Types of Intermittent Reinforcement
  • Ratio
  • Depends on the number of responses made.
  • Interval
  • Depends on the time between reinforcements.
  • Fixed
  • Rewards are spaced at uniform time intervals or
    after a set number of responses.
  • Variable
  • Rewards that are unpredictable or that vary
    relative to the behavior.

21
Classical vs. Operant Conditioning
  • CLASSICAL
  • Stimulus precedes the response and elicits it
  • Elicited responses
  • Learning as a result of association
  • Pavlov
  • OPERANT
  • Stimulus follows the response and strengthens it
  • Emitted responses
  • Learning as a result of consequences
  • Skinner

22
The Basic Concepts of Learning Theory
  • Classical conditioning
  • elicits response as a result of associating
  • unconditioned stimulus
  • neutral stimulus
  • Operant conditioning
  • emitted response
  • learning is a result of consequences
  • reinforcers
  • punishment

Learning
Observational Learning
25
Social Learning Theory (1 of 3)
  • Emphasizes that people learn by observing other
    persons (models) whom they believe are credible
    and knowledgeable
  • Recognizes that behavior that is reinforced or
    rewarded tends to be repeated
  • The models behavior or skill that is rewarded is
    adopted by the observer

26
Social Learning Theory (2 of 3)
  • Learning new skills or behavior comes from
  • directly experiencing the consequences of using
    behavior or skills, or
  • the process of observing others and seeing the
    consequences of their behavior
  • Learning is also influenced by a persons
    self-efficacy
  • self-efficacy a persons judgment about whether
    he or she can successfully learn knowledge and
    skills

27
Social Learning Theory (3 of 3)
  • Self-efficacy can be increased using
  • verbal persuasion offering words of
    encouragement to convince others they can learn
  • logical verification perceiving a relationship
    between a new task and a task already mastered
  • observation of others (modeling) having
    employees who already have mastered the learning
    outcomes demonstrate them for trainees
  • past accomplishments allowing employees to
    build a history of successful accomplishments

28
The Learning ProcessLearning Styles
29
Application of learning in Behavior Modification
(OB Mod)
  • The application of reinforcement concepts to
    individuals in the work setting
  • Follows the Five-Step Problem-Solving Model

30
Assignment Experiential question to be discussed
after studying the topic
  • Do you think manager will be able to more
    effectively change their subordinates
    performance by using rewards or by using
    punishment?
  • However you answer what specific steps you would
    take to make these efforts most effective.Explain
    your recommendations.
  • Good Luck
