instrumental conditioning Flashcards
types of instrumental conditioning
presenting or removing a positive reinforcer, presenting or removing a negative reinforcer
reward training
involves the presentation of a positive reinforcer following a response which increases the frequency of the behvaiour
punishment
presentation of a negative reinforcer
omission training
removing a positive reinforcer leading to a decrease in the behaviour being reinforced, removing a positive reinforcer is a situation a person would want to avoid
escape training
when a response is followed by the removal of a negative reinforcer (e.g. if a rat is being shocked from one side of the cage, move to the other side)
contingencies
the process of acquisition leads to learning the contingency between a response and its consequences
graphing responses
the flat horizontal line on the graph indicates when the subject is not responding, each upward slope indicates when a response has been made
auto shaping
behaviours can be learned without careful guidance by the researcher, subject will learn the contingency on their own (e.g. pigeon pecking at a keyhole and it giving him food every time, self taught
shaping
- organized into smaller steps
- each step can be reinforced through reward training
- over time get the final response wanted
discriminative stimulus (SD)/ (S+)
signals when a contingency is “on” e.g. to a child, their grandparents house becomes SD for vegetable eating behaviour leading to reward of dessert if veggies eaten
S-delta/ S-
indicates when the contingent relationship is not valid e.g. parent’s house= no reward for eating veggies
ratio
based on the number of responses made by a subject, which determines when reinforcement is given
interval
based on the time since that last response was reinforced
4 schedules of reinforcement
- fixed ratio
- variable ratio
- fixed interval
- variable interval
fixed ratio (FR)
-certain behaviour must take place certain amount of times to achieve wanted response
