Answer:
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.

<span>The political landscape was full of corruption.</span>
Virtually every crime gun in the United States starts off as a legal firearm. Unlike narcotics or other contraband criminal arms trafficking is widespread in regions of political turmoil, it is not limited to such areas, for example, in South Asia, an estimated 63 million guns have been trafficked into India and Pakistan.
While illegal guns often pass through multiple trafficking channels, the report confirms that corrupt gun dealers and gun shows present challenges to enforcement. Although gun dealers were involved in less than 10 percent of the investigations, they were associated with the largest total number of diverted firearms (over 40,000 guns) and the highest average number of guns per investigation (350). Gun shows had the second highest number of trafficked guns per investigation (more than 130) and were associated with over 26,000 diverted guns.
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions).
