Assignment:

For each measure below, indicate which kinds of reliability would need to be evaluated. What are the keys words that helped you decide? (see pages 125-127)

1. Researchers place unobtrusive video recording devices in the hallway of a local high school. Later, coders view tapes and code how many students are using cell phones in the 4-minute period between classes.
2. Clinical psychologists have developed a seven-item self-report measure to quickly identify people who are at risk for panic disorder.
3. Psychologists measure how long it takes a mouse to learn an eyeblink 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 the blue light alone (without the air puff). The mouse is said to have learned the eyeblink response if observers record that it blinked its eyes in response to a test trial. The earlier in the 60 trials the mouse shows the eyeblink response, the faster it has learned the response.
4. Educational psychologists use teacher ratings of classroom shyness (on a 9-point scale, where 1 = not at all shy in class and 9 = very shy in class) to measure children's temperament.
