LEARNING THEORIES, MOTIVATION AND HUMAN
ACHIEVEMENT
zarinah- FEM 4101 2
LEARNING THEORIES• Learning theory: belief that behavior could be better
explained by principles of learning than by instinct– John B. Watson (1878-1952) (School of Behaviorism)
• Concluded that there were only three innate emotional reactions: fear, rage, and love.
– Clark Hull (1884-1952) (Drive theory)• Energy for behavior is the result of drives; behavior is caused by the
multiplicative effect of drives times habit (Behavior = Drives x Habits)
– B. F. Skinner (1904-1990) (Reinforcement Theory)• Behavior can be learned even if there is no biological drive
reduction• Behavior modification: altering behavior based on the systematic
applications of rewards– Social Learning Theories: Many behaviors (habits) can be
acquired in the absence of rewards
zarinah- FEM 4101 3
• Rewards as:
– Reinforcers for learning new behaviors
– Incentive stimuli that motivate approach behaviors
REWARD
zarinah- FEM 4101 4
REWARD
• A reward is something given in exchange for something such as money, trophy, medal or any things wonderful.
• A process that reinforces behavior to increase in intensity.
• The functions of rewards are based directly on the modification of behavior and less directly on the physical.
zarinah- FEM 4101 5
INCENTIVE
• Incentive is any factor (financial or non-financial) that provides a motive for a particular course of action, or counts as a reason for preferring one choice to the alternatives
• Incentive occur before an action or behavior.
zarinah- FEM 4101 6
PUNISHMENT
• Punishment is the practice of imposing something unpleasant or response to an unwanted behavior
• Punishment is the reduction of a behavior via a stimulus applied ("positive punishment") or removed (“negative punishment")
zarinah- FEM 4101 7
Reward as Reinforces
• Skinner defined a reinforcer as any stimulus following a behavior that increases the probability that the behavior will occur again.
• A punisher is any stimulus following a behavior that decreases the probability that the behavior will occur again.
• Reinforcers are desirable outcomes of behavior, and punishers are aversive outcomes of behavior.
zarinah- FEM 4101 8
Reward as Reinforces
• Reinforcers are most effective if given immediately after a response and are progressively less effective with longer delays.
• The delay between a response and a reinforcer can be bridged by a secondary reinforcer, a stimulus that gets its reinforcing power by previous association with some reinforcer.
zarinah- FEM 4101 9
Maintaining Behavior: Schedules of Reinforcement
• A schedule of reinforcement is some rule for when to deliver reinforcers in relation to responses
• Schedules can be response-based or time-based.
zarinah- FEM 4101 10
• Response-based: Delivering a reinforcer after every tenth response (a fixed ratio schedule)
• Time-based: Reinforcing the first response after some minimum amount of time has passed since the last reinforcement (a fixed interval schedule).

• Response Theories
• Motivational Theories
• Stimulus Theories
THEORIES OF REINFORCERS
zarinah- FEM 4101 12
• Response Theories: the effective rewarding events are the responses made, not the subsequent stimuli
1. Functional analysis
2. The Premark principle
3. Elicitation theories
4. The Glickman-Schiff biological theory
Response Theories
zarinah- FEM 4101 13
Response Theories
1. Functional analysis• Reinforces functionally: Any stimulus
following a response that increases the probability of that response’s recurring is a reinforcer (Skinner, 1938)
• It is difficult to say in advance what will be a good reinforcer for a given person in a given situation
• Tried and True stimuli sometimes fail to modify human behavior in the way we expect them to do.
zarinah- FEM 4101 14
2. The Premark principle• A more systematic functional analysis
(Premark, 1959).• Any Response A will reinforce any other
Response B, if A has a higher response rate than B
• Experiment: Operating a candy machine or pinball machine• getting candy reinforced playing pinball – eaters• playing pinball reinforced getting candy -
manipulators
Response Theories
zarinah- FEM 4101 15
3. Elicitation Theories (Denny & Adelman)• Requirement for reinforcement: A response be
repeatedly elicited by some stimulus.• Example:
• Animal gets food following lever pressing
Lever Pressing Running to Food Response (Eating Food)
Response Theories
zarinah- FEM 4101 16
4. The Glickman-Schiff biological theory (Glickman & Schift, 1967)
• A stimulus would be reinforcing if it just activated the neural systems underlying responses even if an overt response did not occur
• Example: Animals will normally eat if the lateral hypothalamus is stimulated and food is available
Response Theories
zarinah- FEM 4101 17
Motivational Theories
• Motivational Theories: Emphasize increases or decreases of drive or arousal as reinforcing
1. Drive reduction theory
2. Evidence for drive reduction
3. Evidence against drive reduction
4. Arousal theory
zarinah- FEM 4101 18
1. Drive reduction theory• Directly ties reinforcement to motivation
by saying that drive reduction is a necessary condition for reinforcement (Hull, 1943)
• Miller (1951a,1959) argued that any strong stimulus has drive properties, but not all need states produce strong stimuli. e.g: milk drunk by a hungry rat was a better
reinfocer in a T-maze than milk tubed directly into the stomach
Motivational Theories
zarinah- FEM 4101 19
2. Evidence for drive reduction Drive-reduction theory is supported by
research on pain reduction, fear and reward-by-fistula
Motivational Theories
zarinah- FEM 4101 20
3. Evidence against drive reduction Suggests that drive reduction may be a
sufficient condition for reinforcement but not that drive reduction is the only or necessary condition.
Motivational Theories
zarinah- FEM 4101 21
4. Arousal theory Either increases or decreases in internal
arousal can be reinforcing as long as they lead to a more optimal level of arousal
Motivational Theories
zarinah- FEM 4101 22
STIMULUS THEORIES
• Stimulus theories: Stimuli that produce positive emotion or provide information are reinforcing
1. Hedonic reinforcers
2. Sex and brain stimulation
3. Stimulus change and information
zarinah- FEM 4101 23
1. Hedonic reinforcers Animals that are not under any known
dietary deficiency and that never have been deprived of food or water will press levers or run through mazes for sweet-tasting substances (e.g.,Young, 1959
STIMULUS THEORIES
zarinah- FEM 4101 24
STIMULUS THEORIES
2. Sex and brain stimulation Sexual arousal appears to be very
reinforcing. Electrical stimulation of the brain produces
excitement in animals and highly reinforcing
zarinah- FEM 4101 25
3. Stimulus change and information 2 explanations that have been proposed to
account for alternation behavior
i. Response inhibition theory: the animal tends not to repeat the same response
ii. Stimulation satiation theory: the animal tends not to go to the same stimulus.
STIMULUS THEORIES

REWARD AS INCENTIVES
• Concept of incentive: Rewards do not necessarily affect specific responses
• Experiments: Shows that changes in incentive value, increasing or decreasing, quickly produce appropriate changes in performance even though not associated with particular response
zarinah- FEM 4101 27
• Human incentives are also related to fantasy.
• Klinger: Proposed that we have commitment to goals (incentives) and this commitment is reflected in our current concerns that persist over time
• Current concerns are shown in fantasy, dream and thougths.
REWARD AS INCENTIVES
zarinah- FEM 4101 28
• Locus of Control is considered to be an important aspect of personality.
• Locus of Control refers to an individual's perception about the underlying main causes of events in his/her life.
LOCUS OF CONTROL
zarinah- FEM 4101 29
• A locus of control orientation is a belief about whether the outcomes of our actions are contingent on what we do (internal control orientation) or on events outside our personal control (external control orientation)." (Zimbardo, 1985, p. 275)
LOCUS OF CONTROL
zarinah- FEM 4101 30
LOCUS OF CONTROL
External Locus of Control Individual believes that his/her behaviour is guided by fate, luck, or other external circumstances
Internal Locus of Control
Individual believes that his/her behaviour is guided by
his/her personal decisions and efforts.
Locus of control is conceptualised as referring to a unidimensional continuum, ranging from external to internal:
zarinah- FEM 4101 31
Self-concept Self-concept as "the perception(s) one has
of oneself in terms of personal attributes and the various roles which are played or fulfilled by the individual." (Beane & Lipka, 1984)
They further noted that self-concept represents the "description an individual attaches to himself or herself... in terms of roles and attributes."
zarinah- FEM 4101 32
• Self concept – determines the goals we set– how we evaluate progress toward those goals– the impact of success and failure on our
future goal-directed behavior
Self-concept
zarinah- FEM 4101 33
Functions of Self-concept
2. To provide context1. To provide information
3. To provide integration
zarinah- FEM 4101 34
Functions of Self-Concept
1. To provide information Provides information that will enable us to
make judgments about we can or cannot do. Individuals whose self-concept
underestimates their skills and talents could find it difficult and even impossible to develop aspirations that might motivate them to set difficult goals
zarinah- FEM 4101 35
Functions of Self-Concept
2. To provide context Humans are inclined to view feedback
regarding their behavior in the context of their enduring aspirations and goals
Example: Receiving a grade of B might mean very little for someone whose only wish to graduate but a great deal for someone who wants to be admitted to medical school
zarinah- FEM 4101 36
3. To provide integration The self-concept is a storehouse of
information about the self and provides the global integration of that information
From the integration of information comes our sense of identity
Functions of Self-Concept

SELF-EFFICACY
• Self-efficacy is defined as a person’s belief in his or her capability to successfully perform a particular task (Bandura, 1997)
• Together with the goals that people set, self-efficacy is one on the most powerful motivational predictors of how well a person will perform at almost any endeavour.
zarinah- FEM 4101 38
• A person’s self-efficacy is a strong determinant of their effort, persistence, strategizing, as well as their subsequent training and job performance.
• Self-efficacy is also a much stronger predictor of how effectively people will perform a given task than either their self-confidence or their self-esteem.
SELF-EFFICACY

THE SELF-REGULATION OF BEHAVIOR
• Self-regulation– The ability to make us of knowledge we have
about that lawfulness of human behavior and use that knowledge to achieve goals that we think are in our best interest or simply goals that will make us happy
zarinah- FEM 4101 40
• Self regulation involves 3 processes
1. Self-observation (self-monitoring)
2. Self-evaluation (self-judgment)
3. Self-reaction (self-incentive)
The Self-regulation of Behavior
zarinah- FEM 4101 41
Self-observation (self-monitoring)
• Before we can change a behavior, we need to become aware of it
• This involves monitoring our behavior.• The more systematically we monitor our
behavior, the more quickly we will become aware of what we are doing.
• Example: Improving our social skills
zarinah- FEM 4101 42
Self-evaluation (self-judgment)
• The next step is to decide if what we are doing is congruent with what we want or our personal standards.
• Personal standards are developed from information that we gain from significant others.
• Social cognitive theory: Most of us possess considerable knowledge about the best course of action to achieve a certain outcome but not to have a clear idea of what we are presently doing.
zarinah- FEM 4101 43
Self-reaction (self-incentive)
• Self-judgments are typically accompanied by affective reactions.
• When we succeed or do well, we experience pleasure or satisfaction,
• If fail or perform poorly a negative mood or dissatisfaction
• These self-reactions lead us to set higher goals or to abandon goal
