A researcher is interested in whether drinking water right before bed increases the likelihood that children will wet the bed at night. The researcher recruits 50 5-year-old children to participate in her study. Twenty-five children are given two glasses of water two hours before their bedtime (one glass per hour) and twenty-five children are prohibited from receiving liquids within two hours of their bedtime.2. A researcher was interested in how children learn how to settle disagreements with peers. The researcher talked to his five-year-old daughter and asked her to describe how she interacted with her peers. The researcher then read a few stories to his daughter about children her age who got into disagreements and asked her what she would do in that situation. The researcher continued to interview his daughter like this for five years.3. University officials have noticed that there is a relationship between scores on the Graduate Record Exm (GRE) and performance in graduate school. Specifically, those students with the highest scores tend to do best in school.4. In an attempt to determine which method would assure the best class attendance, an educational psychologist had one teacher reward students for attending class with extra points, a second teacher punish absences by deducting points, a third teacher scold students for absences, and a fourth teacher do nothing unusual. Attendance was best in the first class where the teacher rewarded the students.5. A researchers is interested in whether people are more likely or less likely to help someone in distress when others are present. Some subjects were testes when they alone were witness to someone in distress, while others were tested when many people were present.

A researcher who was suspicious that hyperactivity in children was related to the amount of sugar in their diet recorded both sugar intake and activity level for a sample of children over a five month period. The results indicated that those children who had consumed the most sure tended to be the most active.8. In an investigation of drug abuse, it was noted that there was a relationship between the ages at which an individual first started experimenting with drugs and the severity of the drug abuse problem. Specially, those who experimented with drugs at the earliest age tended to be those with the most severe drug abuse problems.9. To investigate the relationship between anxiety and test performance, three groups of subjects are tested under one of the following conditions: high anxiety, moderate anxiety, low anxiety. The moderate anxiety group performs between on the test than either the high anxiety or the low anxiety groups.10. Researchers looking at the relationship between intelligence and birth order found that the children with the highest IQ scores were most likely to the first born in the family.11. In a study of animal motivation, researchers varied the number of hours their laboratory animals were deprived of food.
