[2] 1 mark for each definition, the two may be described together and may be defined by example.
∞ deprivation is doing without something = 1 mark
∞ deprivation is for example an animal not being given food / water = 1 mark
∞ aversive stimuli are things (which are present) that the animal does not like / is afraid of / that hurt = 1 mark
∞ aversive stimuli include electric shocks / aggressive animals / loud noises = 1 mark
∞ water: deprivation is having none, being forced to swim in it is aversive = 2 marks
∞ other animals (for a social species): none is deprivation, too many is aversive = 2 marks
