There are four interrelated goals of psychology research:
answer
Describe Behavior Predict Behavior Explain Behavior Control Behavior
question
Describing Behavior
answer
Identify regularly occurring sequences of events or rare/complex events Includes both environmental events (stimuli) and behavioral events (responses) Asks "what happens, and in what circumstance(s)?"
question
Predicting Behavior
answer
Some research in psychology aims to develop laws that enable scientists to predict behavior with some probability greater than chance To say that behavior follows laws is to say that regular and predictable relationships exist between variables
question
Explaining Behavior

question
Suppose I wanted to know whether it takes someone longer to match pictures depending upon the rotational orientation of the pictures. I pick 10 simple pictures of objects such as chairs and fruit and present one picture on the left and one on the right to 30 participants.
