Outline of issue (a question)

ecological validity refers to the extent to which the environment, or tasks the participants is asked to do in  piece of research will generalise to other environments or tasks outside of the study setting. Mainly it looks at the realism of the environment and tasks set. If a piece of research is high in ecological validity it is easy to relate the environment or tasks to real life whereas a study conducted in very artificial conditions with artificial tasks would be said to be low in ecological validity.
