Marcus, who runs a software development company, repeatedly gives his administrative assistant, shana, small pay raises for her hard work. lately however, marcus neglects to acknowledge the accomplishments of shana with small pay raises; shana’s performance has begun to decline. what likely contributed to shana’s performance problems?

Extinction            

Explanation:

Extinction: The term extinction is defined as the moderate weakening of a specific conditioned response that gives rise to the disappearing behavior. Hence, the conditioned behavior will stop gradually.

In other words, if a particular behavior is not being reinforced continuously then there the behavior will disappear. It can occur in most of the behavioral conditioning techniques, but majorly in operant conditioning.

In the question above, Shana’s performance problems are mostly contributed by extinction.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
