Outline classical conditioning
Unconditioned stimulus creates a unconditioned response. Neutral stimulus gets paired with unconditioned response, then the conditioned stimulus creates a conditioned response
Components of acquisition with classical conditioning
Timing and repetition
Stimulus generalisation
similar conditioned stimuli
Stimulus discrimination
Must be a specific conditioned stimulus

Punishment
Something the makes them less likely to behave that way
Positive reinforcement/punishment
Adding a stimulus/consequence to a behavior
Negative reinforcement/punishment
Removing a stimulus/consequence to a behavior
Primary reinforcer

Variable ratio
Reinforcement/punishment occurs after a variable number of responses (mow the lawns 3-6 times get paid)
Fixed interval
Reinforcement/punishment occurs after a fixed period of time
Variable interval
Reinforcement/punishment occurs after a variable period of time

Attribution theory
Interpreting and explaining causal relationships

Attribution errors
Fundamental attribution error (FAE), ignoring situational causes
Self-serving bias, not my fault, external cause
Perception of pain depends on
attention, mood & cognition
Chronic pain
Pain that lasts >3 months, is difficult to treat & diagnose
Gate control theory
Blocking pain with proprioceptive sensory stimulus. Ascending messagegs are biological, descending messages are psychological.
Main response to pain
Withdrawl
Cognitive triangle
Thoughts/feelings/behaviour
Active coping
Controlling the pain actively
Passive coping
Avoiding pain rather than management
Jean Piaget’s theory name
Cognitive development stage theory. 4 stages
Stages of cognitive development stage theory
- Sensorimotor
- Preoperational stage
- Concrete operational stage
- Formal operational stage
Scheme
Mental structure made up of organised groups of memories.

Reality conforms with someone’s scheme
Accommodation
Having to alter your scheme to reflect reality
