You Are a Research Assistant in a Developmental Psychology Program

You are a research assistant in a developmental psychology program, and tasked with observing children's expression of feelings and emotions, on the playground, to other children and adults. How intensive or extensive would your categorization system be? In your response, (a) explain and justify why you would use a primarily intensive or extensive category system, and (b) provide an example for how five units of observation would be categorized in your system (i.e., provide 5 examples of behavior or other units of observation that would be noted in your categorization system - are those observations hierarchically or laterally organized?).
