One characteristic of a science is: Control Examples of what we would want to control in psychology include Confounding Varibles (Participants age,gender.The environment, temprature). Laboratory experiments=BEST example of control.
Why is it an Advantage? Will allow us to establish a Cause+Effect relationship → able to make predictions of future behaviour and actions. Controlling them is a huge advantage, allows us to be CONFIDENT! in our results and gives them High Experimental Validity.
Research Examples:
Loftus + Palmer study on eyewitness testimony. The lab setting meant confounding variables could be controlled eg. Using same video of car crashes whilst an IV was manipulated ie. Leading question, to provide results with High Experimental Validity.
