The Predictably Unpredictable Operant
Animals can learn to repeat a response when reinforcement is contingent upon accurate repetitions or to vary when reinforcement is contingent upon variability.

Particular levels of variability or (un)predictability can be reinforced, including responses that approximate a ...

This relationship is robust across species, but evidence is ambiguous within species. We do not know whether individual males reduce their care when paired with cheating females compared with when paired with faithful females (within-male adjustment) or, alternativel...
متن کاملIndividual emergency physician admission rates: predictably unpredictable.

Parents can effortlessly assist their child to walk, but the mechanism behind such physical coordination is still unknown. Studies have suggested that physical coordination is achieved by interacting humans who update their movement or motion plan in response to the partner's behaviour. Here, we tested rigidly coupled pairs in a joint reaching task to observe such changes in the partners' motio...
