Study Notes
B.F. Skinner's Positivism
- Skinner's approach to science was heavily influenced by Francis Bacon and, to a lesser extent, Ernst Mach.
- He believed scientists should focus on collecting empirical facts and using those facts to infer knowledge, rather than developing theories and deducing facts from those theories.
- Skinner viewed science as descriptive and inductive rather than theoretical and deductive.
- Skinner's approach was nontheoretical, rejecting the theoretical aspects of logical positivism.
- He believed that logical positivism allowed for too many confounding variables to influence empirical research.
- His primary focus was on manipulating environmental events and observing their effects on behavior.
- This is known as functional analysis.
Functional Analysis of Behavior
- A functional analysis examines the relationship between environmental events and behavioral events.
- This approach excludes internal events, as they are events themselves and require explanation.
- Skinner believed internal events could not serve as explanations or causes of behavior.
- He referred to this as the "empty organism" approach.
- Skinner was not interested in the internal workings of organisms or participants.
Operant Behavior
- Skinner identified two types of behavior:
- Respondent behavior: This is behavior linked to environmental stimuli, like reflexes. (Watson and Pavlov primarily studied this type of behavior)
- Operant behavior: Behavior influenced by its consequences. It operates on the environment, producing consequences. (Modeled on Thorndike's work).
Operant Conditioning
- Skinner's free operant methodology enables organisms to respond freely in experimental chambers (Skinner Boxes).
- The experimental environment allows for the reinforcement of specific responses based on predefined contingencies (predetermined rules).
- This highlights the power of reinforcement.
- For example: An organism may make a few lever presses without reinforcement, but will significantly increase the rate of lever pressing when reinforcement is introduced.
- Operant conditioning occurs when an organism's behavior is altered by the consequences it produces.
Reinforcement
- Reinforcement is the process by which a consequence of a behavior increases the probability or rate of that behavior.
- Reinforcers are identified solely by their effects on behavior.
- Any consequence can be a reinforcer as long as it increases the probability of the behavior it follows.
Schedules of Reinforcement
- Fixed Ratio: Reinforcement is delivered after a set number of behaviors (e.g., buy 10 coffees, get 1 free).
- Variable Ratio: Reinforcement is delivered after a random number of behaviors (e.g., slot machines).
- Fixed Interval: Reinforcement is delivered for behavior after a fixed amount of time (e.g., Tuesday discount prices).
- Variable Interval: Reinforcement is delivered for behavior after a random amount of time (e.g., checking a phone for a message).
Reinforcement Contingencies in the Environment
- Environmental contingencies influence which behaviors are increased and which are not.
- Altering these contingencies leads to changes in behavior. (Selection of behavior by consequences)
- Darwinian ideas can be applied to this concept.
- Organism produces a variety of behaviors.
- Some behaviors lead to consequences that increase their frequency (functional, reinforcing).
- These effective behaviors are selected to be part of the organism's repertoire, while others are not.
Controlling Behavior: Reinforcement vs. Punishment
- Reinforcement exerts a more effective control over behavior than punishment.
- Skinner believed that unwanted behaviors should be ignored, and parents should focus on reinforcing desired actions.
Applications
- Changing reinforcement contingencies leads to behavior change.
- Education: Skinner criticized the school system's reliance on punishment rather than reinforcement contingencies.
-
Behavior Therapy: Treatment centers on eliminating reinforcers for abnormal behavior and arranging contingencies to strengthen desirable behavior.
- Token economies are commonly used.
Behaviorism Today
- Skinner remains the most influential behaviorist.
- Behaviorism and neobehaviourism have lost influence due to factors such as:
- Evidence of genetic influence on behavior.
- Criticisms of logical positivism.
- The major legacy of behaviorism: Psychologists generally now agree that the subject matter of psychology is overt behavior.
