What did Clever Hans contribute to psychology?
Using this method, Hans amazed both the general public and leading psychologists of the day with his apparent ability to perform arithmetic functions, identify colours, read and spell, and even identify musical tones.
What did Clever Hans teach us?
What Clever Hans teaches us about being human is that there’s a danger to being so dazzled by the seeming impossibility of an animal’s intellect that we’re blinded to our own actions. Hans achieved something substantial, which was to open a dimension of human behavior that had previously been unstudied.
What was the hypothesis of the Clever Hans experiment?
Pfungst hypothesized that Hans’ cleverness relied on him having a close, unobstructed view of a person who knew the correct answer.
What was Clever Hans responding to?
In other words Hans was responding to a simple, involuntary postural adjustment by the questioner, which was his cue to start tapping, and an unconscious, almost imperceptible head movement, which was his cue to stop. Yet, more than a dozen scientists observed Hans and were convinced there was no signaling or trickery.
How did the case of Clever Hans impact the development of psychology quizlet?
Clever Hans (the horse) had the knowledge of a 14 year old boy. He was on a commercial, he was like a celebrity. What ways had psychology changed by the second decade of the 20th century? There was no longer introspection they wanted to start using behaviorism in the 20th century, this is why psychology changed.

Hans solved calculations by tapping numbers or letters with his hoof in order to answer questions. Later on, it turned out that the horse was able to give the correct answer by reading the microscopic signals in the face of the questioning person.
How does the case of Clever Hans illustrate the concept of a self fulfilling prophecy?
The story of Clever Hans echoes the idea of the self-fulfilling prophecy in people leadership; the way that we treat others is subtly influenced by what we expect of them. In turn, these expectations have an impact on how the other person behaves and how they feel.

How did Clever Hans solve arithmetic problems quizlet?
Wilhelm von Osten’s horse that could solve math problems by tapping his hoof. Psychologist Oskar Pfungst eventually discovered that Clever Hans was taking cues from von Osten when answering problems (when to start tapping and when to stop).
How do researchers guard against the Clever Hans effect?
Some ways to prevent the Clever Hans Effect are for the experimenter to be unaware of the correct answers (a “double-blind” study), or to have the experimenter hidden out of sight of the subject. Either way, the experimenter is unable to inadvertently cue the subject to the correct answer.
How did scientists discover the truth of Clever Hans?
During a series of experiments, Pfungst noticed that Clever Hans often didn’t know the correct answer when the questioner didn’t know it either. Furthermore, if the horse couldn’t see anyone who did know the answer, Hans didn’t respond correctly. It turned out Clever Hans had learned to detect subtle nonverbal cues.
