Instinctual drift is the tendency of some trained animals to revert back to instinctual behaviors. In other words, they will behave in accordance with evolutionary contingencies, as opposed to the operant contingencies of their training. These behaviors are often unnecessary, and seldom useful. The article addressed some deficiencies in B. In his book, Skinner described the Skinner Box and the basics involved with operant conditioning.
His work seemed to assert that all animals started off on equal footing when it came to operant conditioning later, he denied that he ever implied this. However, after working with a variety of species for 25 years, the Brelands reached a different conclusion. The pigs were being trained to pick up large wooden nickels in their mouths and deposit them into piggy banks. Depositing coins was reinforced with food. These animals had already been taught that all that they had to do to earn food was drop the coins in the bank.
Summary Biological Influences. Taste Aversion Psychologist John Garcia and his colleagues found that aversion to a particular taste is conditioned only by pairing the taste a conditioned stimulus with nausea an unconditioned stimulus. An Evolutionary Adaptation The combination of taste and nausea seems to be a special case. Popular pages: Learning and Conditioning. Take a Study Break. Similarly, raccoons that had been taught a similar task would persistently fondle the coins before dropping them into the bank or, perhaps, periodically dip the coin into the bank as though washing it.
When provided with more than one coin at a time, the raccoons would tend to rub them together instead of dropping them into the box as they had been trained to do. The general principle seems to be that wherever an animal has strong instinctive behaviors in the area of the conditioned response, after continued running the organism will drift toward the instinctive behavior to the detriment of the conditioned behavior and even to the delay or preclusion of the reinforcement.
In a very boiled-down, simplified form, it might be stated as "learned behavior drifts toward instinctive behavior. It is interesting to note that the sensory-motor modalities involved in this phenomenon are consistent with an interpretation involving corticothalamic dominance previously discussed see Chapter 3. Under Welker's model of thalamocortical dominance, pigs are rooters, raccoons are feelers, and pigeons are beholders. Furthermore, some self-reinforcement stemming from hy-pothalamic-limbic feedback occurring during the emission of appetitive behavior may help to explain instinctive drift while at the same time preserving reinforcement theory.
The locus of reinforcement supporting instinctive drift is internally articulated on brain reward sites associated with drive induction and preparatory appetitive responding. The arbitrary operant, on the other hand, may be more adequately conceptualized as belonging to or conditionally associated with the con-summatory action and subsequent drive reduction.
Although both are reinforcing, the action of preparing to eat may be intrinsically more rewarding than eating itself. Motiva-tionally, this makes a lot of sense, since it requires a lot more effort therefore, a lot more incentive and conditional reinforcement prior to consumption to find food than to eat it. Many other problems with the traditional conceptualization of appetitive operant learning have emerged in the laboratory.
