a perceptual set
Explanation:
According to my research on various studies conducted by psychologists, I can say that based on the information provided within the question Mary's error in identifying the voice illustrates the effect of a perceptual set. This term refers to a predisposition within individuals to expect something in a certain way based on some information. Which in this case is what happened with Mary since she was expecting her husband to call based on him saying he would call before lunch.
