actions may not end up so harmonious, because they suffer from differential reinforcement.

What does "differential reinforcement" mean? If you covered it in the previous post, a link or summary would be good.

From Wikipedia:

Other simple (reinforcement) schedules include:

Differential reinforcement of incompatible behavior – Used to reduce a frequent behavior without punishing it by reinforcing an incompatible response. An example would be reinforcing clapping to reduce nose picking.

Differential reinforcement of other behavior (DRO) – Also known as omission training procedures, an instrumental conditioning procedure in which a positive reinforcer is periodically delivered only if the participant does something other than the target response. An example would be reinforcing any hand action other than nose picking.

Differential reinforcement of low response rate (DRL) – Used to encourage low rates of responding. It is like an interval schedule, except that premature responses reset the time required between behavior.

Lab example: DRL10" = a rat is reinforced for the first response after 10 seconds, but if the rat responds earlier than 10 seconds there is no reinforcement and the rat has to wait 10 seconds from that premature response without another response before bar pressing will lead to reinforcement.

Real world example: "If you ask me for a potato chip no more than once every 10 minutes, I will give it to you. If you ask more often, I will give you none."

Differential reinforcement of high rate (DRH) – Used to increase high rates of responding. It is like an interval schedule, except that a minimum number of responses are required in the interval in order to receive reinforcement. Lab example: DRH10"/15 responses = a rat must press a bar 15 times within a 10 second increment to get reinforced Real world example: "If Lance Armstrong is going to win the Tour de France he has to pedal x number of times during the y-hour race."
