What is a Behavior? 1) Observable 2) Definable 3) Measurable
- frequency (how often does it occur?) - duration (how long does it occur?)
3
Behavioral and Social Cognitive Approaches
Learning is a relatively permanent change in behavior that occurs through experience. There are five major approaches to learning. 3
4
Behavioral and Social Cognitive Approaches
Behaviorism: Behavior is explained by observable experiences. Mental Processes The observable thoughts, feelings, and motives that we experience Associative Learning that two Learning events are connected Cognitive: Includes social cognitive, information processing, cognitive constructivist, and social constructivist 4
5
Contiguity or Associated Learning
Learning by simple associations: Pairing Stimulus → Response Examples: Golden Arches = McDonalds Times tables (7 X 8 = 56) States & capitals (Lansing, MI)
6
Classical or Pavlovian Conditioning
We learn to associate two stimuli

Behavioral and Social Cognitive Approaches
Approaches to Learning Classical Conditioning Operant Conditioning 7

Classical Conditioning
Ivan Pavlov Russian physician/ neurophysiologist Nobel Prize in 1904 studied digestive secretions
9
Behavioral Approaches
Classical Conditioning is a type of learning in which an organism learns to connect or associate stimuli. A neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. 9
10
Classical Conditioning
Unconditioned Stimulus (UCS) stimulus that unconditionally--automatically and naturally--triggers a response Unconditioned Response (UCR) unlearned, naturally occurring response to the unconditioned stimulus salivation when food is in the mouth
11
Classical Conditioning
Conditioned Stimulus (CS) originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response Conditioned Response (CR) learned response to a previously neutral conditioned stimulus
12
Acquisition The CS needs to come half a second before
the US to cause acquisition.

When Christina was a baby, her parents would drive her around in the car to get her to fall asleep because the feeling of motion automatically made her drowsy. As an adult, Christina feels drowsy whenever she sits in a car, even when it is not moving.

Whenever Jim’s father drinks too much, he gets very violent and beats Jim severely. This has happened on several occasions. Now, just the smell of beer makes Jim fearful. What is the unconditioned stimulus (US)? _________________________________ What is the unconditioned response (UR)? _________________________________ What is the conditioned stimulus (CS)? ___________________________________ What is the conditioned response (CR)? ___________________________________

The Troublesome Shower (example of an acquired behavior via CC)
Martin is taking a shower in the men’s locker room after working out. While in the shower he hears someone flush a toilet. Suddenly, very hot water rushes out of the shower head causing Martin to get slightly burnt. As he continues to shower, he hears another toilet flushing and immediately jumps out from under the shower head.

Classical Classroom Examples
A first grader feels ill when recess time approaches because he was beat up on the playground the last 3 days in a row. Certain smells that can elicit nauseous sensations (Hopefully NOT from the cafeteria!) Speech phobia : cold sweat, shaking knees and hands Phobias in general
22
Behavioral Approaches Classical Conditioning
Generalization The tendency of a new stimulus similar to the original conditioned stimulus to produce a similar response. Discrimination The organism responds to certain stimuli and not others. Extinction The weakening of the conditioned response (CR) in the absence of the unconditioned stimulus (US). 22
23
Behavioral Approaches Classical Conditioning
Systematic Desensitization reduces anxiety by getting the individual to associate deep relaxation with successive visualizations of increasing anxiety-producing situations. 23
24
Pavlov’s Classical Conditioning Theory into Practice
Patty does poorly on a math test. This makes her feel anxious. From that point on, she always becomes anxious when taking a math test. As the school year progresses, she begins experiencing anxiety when she has tests in other subject areas as well. Q.1: Identify the US in the example above. Q.2: Identify the UR in the example above. Q.3: Identify the CS in the example above. Q.4: Identify the CR in the example above. A1: The unconditioned stimulus is doing poorly on the math test. A2: The unconditioned response is anxiety. Anxiety is a natural response to failure. A3: The conditioned stimulus is math tests. Once Patty has associated the test with failure, she begins to experience anxiety in response to math tests. A4: The conditioned response is anxiety. 7.24

Pavlov’s Classical Conditioning Theory into Practice
Patty does poorly on a math test. This makes her feel anxious. From that point on, she always becomes anxious when taking a math test. As the school year progresses, she begins experiencing anxiety when she has tests in other subject areas as well. A: She is experiencing stimulus generalization. She has generalized her anxiety response to similar stimuli—tests in other content areas. Q: Why would Patty begin to experience anxiety in response to tests in content areas other than math? 7.25
26
Behavioral Approaches
Operant Conditioning is a form of learning in which the consequences of behavior produce changes in the probability that the behavior will occur. Thorndike’s Law of Effect Behavior Positive Outcome Behavior Strengthened Behavior Negative Outcome Behavior Weakened 26
27
Operant Conditioning B.F. Skinner (1904-1990)
elaborated Thorndike’s Law of Effect developed behavioral technology
28
Behavioral Approaches
Skinner’s Operant Conditioning Operant Behavior - operates (acts) on environment produces consequences Consequences (rewards and punishments) are contingent on the organism’s behavior. Reinforcement (reward) increases the probability that a behavior will occur. Punishment decreases the probability that a behavior will occur. 28

Reinforcement Examples
Primary Reinforcers: Food Water Warmth Security Sex Copyright © Allyn & Bacon 2006

Reinforcement Examples
Secondary Reinfocers Money Grades Stars Praise Copyright © Allyn & Bacon 2006
31
Types of Reinforcement
Positive reinforcement – giving something that the person wants that increases the behavior Examples: Praise Teacher attention Rewards Negative reinforcement – taking away something that the person does not want that increases the behavior Chores Taking away time-out
32
Types of Punishment Presentation Punishment (type I) – giving something that the person does not want that decreases the behavior Detention Extra work Removal Punishment (type II) – taking away something that the person wants that decreases the behavior Loss of recess Loss of privileges
33
Behavioral Approaches
Generalization Giving the same response to similar stimuli. Discrimination Differentiating among stimuli or environmental events. Extinction Previously reinforced response is no longer reinforced and the response decreases. One way to deal with a child’s temper tantrum is to ignore it resulting in extinction 33
34
Skinner’s Operant Conditioning Theory into Practice
Nick frequently gets out of his seat and entertains his classmates with humorous remarks. Mr. Lincoln often scolds Nick for his behavior. However, Nick’s classmates laugh when Nick makes remarks. The scolding rarely has any impact. Nick continues with his antics. Q.1: What is Mr. Lincoln attempting to do when he scolds Nick? Q.2: Why does Nick continue his antics in spite of being scolded? Q.3: What are three strategies Mr. Lincoln could try to keep Nick more on task? A1: He is attempting to present Nick with an aversive stimulus—he is attempting to punish Nick. A2: Nick’s classmates are reinforcing his behavior by laughing and/or Nick does not mind being scolded. Perhaps he enjoys the attention. A3: Differential reinforcement—he could reinforce Nick for behaving appropriately Contracting—he could contract with Nick. If Nick behaves appropriately for a period of time, he would receive some sort of reinforcement Prompting—he could develop a signal to Nick to get back on task. This could be a frown, a tap on the shoulder or desk, or just making eye contact. Terminate reinforcement—he could stop giving Nick attention for his behavior (this may not work because it is difficult to elicit the cooperation of the rest of the class to not laugh at something that is funny) Remove desirable stimuli—Nick may benefit from time-out Response cost—Nick could lose privileges when he misbehaves 7.16
35
Schedules of Reinforcement
Continuous Reinforcement reinforcing the desired response each time it occurs Partial (Intermittent) Reinforcement reinforcing a response only part of the time results in slower acquisition greater resistance to extinction
36
Reinforcement Schedules

37
Schedules of Reinforcement: Frequency and Predictability
Fixed Ratio: reinforcer given after fixed number of behaviors Fixed Interval: reinforcement only at certain periodic times Variable Ratio: reinforcer given after unpredictable number of behaviors Variable Interval: reinforcement at some times but not others Copyright © Allyn & Bacon 2006

Francis sells jewelry to a local gift shop. Each time he completes 10 pairs of earrings, the shopkeeper pays him for them. This is an example of a ___________ schedule of reinforcement. A. Fixed ratio B. Variable ratio C. Fixed interval D. Variable interval Sandra’s mail is delivered every day at 10:00. She checks her mailbox several times each morning, but only finds mail the first time she checks after 10:00. This is an example of a __________ schedule of reinforcement

Vernon is practicing his golf putting
Vernon is practicing his golf putting. On the average, it takes him four tries before the ball goes in the hole. This is an example of a _________ schedule of reinforcement A. Fixed ratio B. Variable ratio C. Fixed interval D. Variable interval Paula is an eager third-grader, and loves to be called on by her teacher. Her teacher calls on her approximately twice each period, although Paula is never sure when her turn will come. This is an example of a __________ schedule of reinforcement

42
Applied Behavioral Analysis Reinforcement: Prompts and Shaping
Prompts: Added stimuli that are given just before the likelihood that the behavior will occur. ─Get behavior going. ─Once desired behavior is consistent, remove prompts. Shaping: Involves teaching new behaviors by reinforcing successive approximations of the desired behavior. ─First, reward any response. ─Next, reward responses that resemble the desired behavior. ─Finally, reward only target behavior. 42

Classroom Uses of Reinforcement
Identify behaviors you want from your students, then reinforce them when they occur. 2. Tell students which behaviors you want; when they occur, reinforce them and explain why the behavior is desirable. 3. Reinforce appropriate behavior immediately. Copyright © Allyn & Bacon 2006
47
Maintenance of Behavior in the Classroom
When teaching a new behavior/skill, reinforcement for correct responses should be: Frequent Predictable When a behavior/skill is established, reinforcement for correct responses should be: Less frequent Less predictable Copyright © Allyn & Bacon 2006
48
Applied Behavioral Analysis Reinforcement
Guidelines for the Classroom: ─Initial learning is better with continuous reinforcement. ─Students on fixed schedules show less persistence, faster response extinction. ─Students show greatest persistence on variable interval schedule. 48
49
Applied Behavioral Analysis Increasing Desirable Behaviors
. 1. Choose effective reinforcers. 2. Make reinforcers contingent and timely. 3. Select the BEST reinforcement schedule. 4. Consider contracting. 5. Use negative reinforcement effectively. 49
50
Applied Behavioral Analysis Decreasing Undesirable Behaviors
1. Use differential reinforcement by reinforcing more appropriate behavior. 2. Withdraw positive reinforcement from a child’s inappropriate behavior. 3. Remove desirable stimuli through “time-out and response cost.” 4. Present aversive (unpleasant) stimuli. 50
51
Bandura’s Social Cognitive Theory
Social, Cognitive, and Behavioral factors play important roles in learning. Self-efficacy: The belief that one can master a situation and produce positive outcomes. Observational Learning occurs when a person observes and imitates someone else’s behavior. 51

Social Cognitive Approaches to Learning Bandura’s Contemporary Model
. Retention Student retention will be improved when teachers give logical and clear demonstrations. Attention Students are more likely to be attentive to high status models (teachers). Production Poor motor ability inhibits reproduction of the model’s behavior. Help improve skills. Motivation When given a reinforcement, modeling increases. 54

Bandura’s Social Cognitive Theory Theory into Practice
Nick frequently gets out of his seat and entertains his classmates with humorous remarks. Mr. Lincoln often scolds Nick for his behavior. However, Nick’s classmates laugh when Nick makes remarks. The scolding rarely has any impact. Nick continues with his antics. After several days of this, other boys in the class begin to get out of their seats and make humorous remarks as well. A1: They have learned from observing Nick that such behavior results in reinforcement from peers. Therefore, they imitate him. A2: Since children are more likely to imitate a high status model, we might assume that Nick has high status among his peers. Q.1: Why do the other boys begin to misbehave? Explain. Q.2: What does this say about Nick? 7.31
