Document Summary

Why learn about research strategies: conduct your own research, research liaison: you might be approached to partner with lab groups to conduct research. Part 1: how do we gather information on children: appreciation for what goes into a single study. Advantage: good external validity ability to generalize inferences. Disadvantage: observer bias & influence: naturalistic observation. Just observe children play in the natural environment: park, playground, etc. All participants have equal chance to display beh. Observer bias: seeing what you want to see. Those with no knowledge of hypothesis are best observers. Habituation 1-2 visits for children < 7-8 years. Train parents or an individual acquainted with the child to do the observing: clinical interviews. Each participant is asked the same questions in the same way. Efficient: lots of data can be collected in a short-period of time. Answers from entire group at same time. Can still be affected by inaccurate reporting.
