Difficult : actively withdraw from social contacts (low end) rather than approach (cid:224) slow to warm up initial reluctance, gradually adapt and actively interact (cid:224) easy unusual ease among people, friendliness, ability and willingness to actively interact and approach anyone. 4 schedules of intermittent reinforcements produced by combo of 2 dimensions: 1) # of responses/period of time since last reinforcement 2) fixed vs. variable reinforcement rate. ratio schedules: reinforcement after certain # of responses made; number fixed (after 5th response) or variable (after 3rd, then 5th). interval schedules: reinforcement if person performs behaviour (at least once) after specified time since last reinforcement; fixed (5 minutes) or variable (after 3, after 7). overall, ratio schedules more effective than interval to maintain a response, but may need continuous reinforcement to establish the response in the 1st place (1) fixed interval: reinforcer for 1st response after time elapsed.
