Perspectives on Learning
l Behavioral: Learning must be observable change in behavior
l Cognitive: Learning is an internal process and cannot be observed directly
Contiguity Learning
l Learning by simple associations: Pairing
l Example:
– Golden Arches = McDonalds

playground the last 3 days in a row.
Certain smells that can elicit nauseous sensations (NOT from the cafeteria!).
Speech phobia - cold sweat, shaking knees and hands.

Reinforcement Schedules
Controlling Antecedents
Antecedents
Providing previous information about expected behaviors
Signaling when a behavior should be emitted
Cueing: Lights off means “Be quiet!”
Prompting: Verbal reminder after students do not get quiet after lights were turned off.
Applied Behavior Analysis
Baseline behavior
Target behavior
Classroom application:
1 - Specify the desired behavior
2 - Plan a specific intervention
3 - Keep track of the results
Interventions: Encouraging Positive Behavior
Teacher attention
Praise & ignore
Premack principle
Shaping
Positive practice
Coping with Undesirable Behaviors
Negative reinforcement: ‘No recess until…’
Satiation: ‘I would like 1000 of those perfect spit wads, please!’
Reprimands: soft & private
Response cost
Social isolation
Punishment
Coping with Undesirable Behaviors
Cautions: Use a two pronged approach:
– Reinforcement
– Punishment
