This essay will discuss the role of ecological validity in psychological research, drawing on material from the DE100 textbook ‘Investigating Psychology’. It will begin by giving a description of what ecological validity is, and consider it in relation to different examples of research. The research used to discuss the role of ecological validity will be based around social learning and aggression, behaviourism, and memory. Firstly the study of Bandura et al. will be considered, his experiments on children copying violent behaviours using the Bobo doll experiment. Then the Skinner box will be discussed, finally leading to the studies of Loftus and Palmer on the link between language and memory. The role and importance of ecological validity in each body of research will be discussed and evaluated.

Using this procedure of reinforcement the animal learned to perform the response to get food as it associates this required behaviour with the reward of food. (Toates, F., 2010, p. 164) This principle can be applied to strengthen any behaviours whether it be positive or negative, and this research is an efficient technique used widely by many
