Rosenthal's Research refers to the work of psychologist Robert Rosenthal, who studied the impact of expectations on performance. His most famous study, known as the Pygmalion Effect, demonstrated that teachers' expectations can significantly influence students' academic achievements. When teachers believed certain students would excel, those students often performed better, highlighting the power of positive expectations. In addition to the Pygmalion Effect, Rosenthal explored the concept of self-fulfilling prophecies, where individuals' beliefs about others can shape their behavior and outcomes. His findings have implications in various fields, including education, management, and psychology, emphasizing the importance of fostering positive expectations.
