If a student is more attentive to the teacher's lecture, the teacher tends to grade them higher even if their work isn't better than that of the students who didn't pay attention.īoth the Pygmalion and Golem effects can happen in other settings, too. When they do, the students tend to slack off more and show worse performance.Ī similar thing can happen to teachers as well. The Golem Effect is similar to the Pygmalion Effect, except that it happens when teachers have low expectations of their students. If a teacher expects the children to perform well, they perform better than they would if the teacher had no expectations. In the Pygmalion Effect, students change their behavior based on what they think the teachers expect from them. Reactivity can happen in a school setting, too.
The horse, then, was responding to what the owner expected of them. Finally, they noticed that if the owner did know the answer, the owner's posture and facial expression changed as the horse's taps approached the correct number. Second, if the horse couldn't see the owner, it couldn't get the answer right, either. First, if the owner didn't know the answer, the horse got the answer wrong most of the time. The researchers noticed several things during their observations. The owner would pose a question, and the horse would tap out the answers with its hoof. A philosopher and a psychologist wanted to find out if a certain horse (known as Clever Hans) could do arithmetic as its owner claimed it could. The concept derives from a study called the " Clever Hans" experiment. Regardless of whether they were intended or not, these cues influence the observer. The Observer-Expectancy Effect occurs when someone is perceived to give subtle cues as to what they expect. This is when the participants alter their behavior based on what they think the experimenter hypothesizes that they will do. If they do, the Experimenter Effect can happen. In a scientific experiment, the researchers must be careful not to let the participants know what they expect the study to show. Scientists see this as an attempt to overcome what the control group participants see as a disadvantage-that nothing interesting will happen in their group, and they will not receive special attention. They compare their behavior to what those in the experimental group are doing and how they’re reacting. It also happens in research studies, but in this situation, the participants change their behavior because they know they're in the control group. The John Henry Effect is a special case of the Hawthorne Effect. When an experimenter singled someone out and gave them attention, they worked harder and performed better.
This effect was named for the Hawthorne Works Plant, where researchers conducted a study on productivity. The Hawthorne Effect happens during research studies when the people participating know they're being studied. The experimenters pay close attention to them, and they may change the way they behave as a result.
