Researchers place unobtrusive video recording devices in the living rooms of 20 children. Later, coders view tapes of the living areas and code how many minutes each child spends playing video gamesClinical psychologists have developed a 7-item self-report measure to quickly identify people who are at risk for panic disorder. A restaurant owner uses a response card with four items in order to evaluate how satisfied customers are with the food, service, ambience, and overall experience. Each item is scaled from one to four stars. Psychologists measure how long it takes a mouse to learn an eye-blink response. For 60 trials, they present a mouse with a distinctive blue light followed immediately by a puff of air. The 5th, 10th and 15th trials are test trials, in which they present blue light alone (without the air puff). The mouse is said to have learned the eye blink response if observers record that it blinked its eyes in response to a blue light test trial. The earlier in the 60 trials the mouse shows the eye blink response, the faster it has learned the response. Educational psychologists use teacher ratings of classroom shyness (on a nine point scale, where 1 = “not at all shy in class†and 9= “very shy in classâ€) to measure children’s temperament.
