Daniel Kahneman. Think slowly... Solve quickly (№ 391341)

Psychologist John barg and his colleagues conducted an experiment, which instantly became a classic example of this effect. Students at new York University at the age of from eighteen to twenty-two years was asked to make a phrase length to four words from sets of five words (e.g., "finds", "it", "yellow", "right", "house"). Sets for one group of students contained words associated with the elderly: "FL", "forgetful", "bald", "gray" or "wrinkles". After finishing the job, the young people had to go to another office to perform the following test. The essence of experiment consisted of in this short passage. Researchers discreetly noted the time required for the passage of the corridor. As barg predicted, young people, formed sentences from words associated with the elderly, walked down the hallway significantly slower.
