Expectancy refers to the anticipation or belief that a certain event or outcome will occur. It plays a significant role in various fields, including psychology, where it can influence behavior and motivation. For example, when individuals expect positive results from their efforts, they are more likely to engage in those activities with enthusiasm. In the context of education, expectancy can affect student performance. If teachers convey high expectations for their students, those students may feel more motivated to succeed. This phenomenon is often linked to the Pygmalion effect, where higher expectations lead to improved performance, demonstrating the power of belief in shaping outcomes.
