Measuring Behaviour
Study Questions Class 21
1. Why is the study of "monsters" and "freaks of nature" important for understanding the
processes of both the evolution and development of behaviour? (4)
2. How do critical periods/ sensitive periods/ vulnerable periods shape development; for
example, with respect to environmental teratogens? (4).
3. How can neonatal behavioural tests be used to detect developmental abnormalities in
children, rats or mice at early ages? E.g. sensory, motor and cognitive deficits? (4)
4. What test is most definitive in discriminating between blind and sighted babies? Why? (3)
5. What are the six commonly used observational methods for studying children's behaviour?
6. What does the Peabody Developmental Scale measure? At what ages? (2)
7. What is the difference between a checklist and a rating scale for scoring children's
behaviour? (2)
8. Rating scales for children's behaviour are often completed by parents or teachers, rather than
by trained observers. Based on your knowledge of observational research methods, what are
6 problems with this type of study? (6)
9. What are four problems in defining children as "hyperactive" based on their mother's
response to a questionnaire? (4)
10. What behavioural tests would you use to test the hypothesis that "hospitalization increases
the level of stress in children"? Design a simple experiment with experimental and control
groups and 4 behaviours to score. What results do you predict? (8)
11. A teacher claims that 10 year old "A" is a bully. Design an observational experiment to test
this. (6).
12. You are observing a group of children. Design an experiment to determine which are
"normal", which are "autistic" and which have "Williams syndrome". (There are some of
each in your group; you have to detect them by their behaviour). (6).
