Q

define continual reinforcement

A

every occurrence of the behaviour is paired with the reinforcer
- learning occurs rapidly
- extinction occurs rapidly

Q

define partial reinforcement

A

only some of the occurrences of the behaviour are paired with the reinforcer
- the lower the proportion of the behaviours that are paired with the reinforcer the more slowly conditioning occurs
- resistant to extinction

can be interval or ratio, fixed or variable

Q

define differential reinforcement

A

animals is given different valued rewards that reflect the quality of the performance
e.g. reward dog for above average response’s, give better rewards for better responses

Q

fixed ratio vs variable ratio

A

fixed - behaviour is reinforced only after behaviour occurs a specified number of times
faster you respond, the more rewards you get

variable - behaviour is reinforced after unpredictable number of times
very hard to extinguish because of unpredictability

Q

fixed interval vs variable interval

A

fixed - behaviour is reinforced only after specific time has elapsed
frequency of behaviour increases when the time of reward draws near

variable - behaviour is reinforced at unpredictable time intervals
produced slow, steady response

Q

what is shaping

A

shaping is the process of building a particular behaviour gradually using a small series of steps to achieve the final behaviour

Q

what are examples of factors that can affect learning

A
  • motivation state (e.g. hunger)
  • biological predisposition
  • environment
  • age
