Jake told Mary that he would call her before lunch. At 11:30 a. m. the phone rang and she responded to the male voice by saying "Hi, honey." It turned out to be her boss calling rather than her husband. Mary’s error in identifying the voice illustrates the effect of

Perceptual set.

Explanation:

A perceptual set is elucidated as the predisposition or susceptibility  to perceive things in a specific manner. It leads to shape our interpretation and response towards a particular stimulus as these are shaped by previously possessed information.

In the given example, Mary's response 'Hi, honey' exemplify this 'perceptual set' which reflects her predisposition to perceive the call in a specific manner(thinking it to be her husband's call) which was shaped by the prior knowledge that she possessed regarding the call(when her husband told her that he would call her in the morning).
