Sleeping pills Anti-anxiety pills | Barbiturates |
• Speed up bodily functions Increase heart rate, breathing Appetite diminishes Increased energy and self-control | Stimulants |
Caffeine Nicotine Cocaine Amphetamines | Stimulants |
• Psychedelic drugs distort perceptions and evoke sensory images in the absence of sensory input LSD | Hallucinogens |
Marijuana Ecstasy | Hallucinogens |
Reduction in serotonin Memory loss Mood regulation Learning | Long term effects of ecstasy |
a relatively permanent change in behavior, knowledge, capability, or attitude that is acquired through experiences and cannot be attributed to illness, injury, or maturation. | Learning |
a type of learning through which an organism learns to associate one stimulus with another. | Classical conditioning |
any event or object in the environment to which an organism responds. | Stimulus |
a learned reflex rather than a naturally occurring one. | conditioned reflexes |
inborn, automatic, unlearned response to a particular stimulus. | Unconditioned reflexes |
Weakening and eventual disappearance of the CR as a result of repeated presentation of CS without the US | Extinction |
Reappearance of an extinguished CR when an organism is exposed to the CS following a rest period | Spontaneous recovery |
Tendency to make a CR to a stimulus that is similar to the original CS | Generalization |
Learned ability to distinguish between similar stimuli so that the CR occurs only to the original CS but not to similar stimuli. | Discrimination |
Conditioned fears “persist to modify personality throughout life” | Watson and Rayner (1920) “Little Albert” study |
the intense dislike and/or avoidance of particular foods that have been associated with nausea or discomfort. | Taste aversions |
A type of learning in which the consequences of behavior are manipulated so as to increase or decrease the frequency of an existing response or to shape an entirely new response. | Operant conditioning |
formulated the law of effect | Edward Thorndike |
The consequence, or effect, of a response determines whether the tendency to respond in the same way in the future is strengthened or weakened | The Law of Effect |
• The law of effect formed the basis for B.F. Skinner’s work on the ? | Operant conditioning |
the causes of behavior are in the environment and do not result from inner mental events, such as thoughts, feelings, or perceptions. | Skinner's definiteion of operant conditioning |
anything that follows a response and strengthens it or increases the probability that it will be repeated. | Reinforcement |
A pleasant or desirable consequence that increases the probability that a response will be repeated (present to increase behavior). | Positive Reinforcement |
- Termination of an unpleasant condition after a response, which increases the probability that the response will be repeated (Remove to increase behavior). | Negative reinforcement |
A reinforcer that fulfills a basic physical need and does not depend on learning | Primary Reinforcer |
A reinforcer that is acquired or learned through association with other reinforcers. | Secondary reinforcer |
Gradually molding a desired behavior (response) by reinforcing any movement in the direction of the desired response. | Shaping |
reinforcement that follows every target response | Continuous reinforcement |
reinforcement that does not follow every target response | Partial reinforcement |
require that a certain number of responses be made before one of the responses is reinforced. | Ratio schedules |
a given amount of time must pass before a reinforcer is administered. | Interval schedules |
Reinforcer given after a fixed number of correct nonreinforced responses. | Fixed Ratio |
Reinforcer is given after a varying number of nonreinforced responses | Variable ratio |
