The observer-expectancy effect occurs when a researcher's beliefs or expectations unconsciously affect the behavior of the observed subject(s). For example, a researcher who believes that certain children are especially talented might unintentionally behave toward those children in ways that lead them to perform better than others, such as by giving those children extra attention and praise. In one famous example of the observer-expectancy effect from the 1900s, Wilhelm von Osten, believing his horse (Clever Hans) capable of solving mathematical problems, unknowingly gave the horse cues that enabled it to answer such problems correctly. Because the observer-expectancy effect biases the results of an experiment, researchers in psychology (and other disciplines) attempt to avoid the effect by performing double-blind experiments, for example. ---------- Psychology tutoring on Chegg Tutors Learn about Psychology terms like Observer Expectancy Effect on Chegg Tutors.
