Describe three different ways that experimental social psychologists can enhance the external validity of their experiments

What will be an ideal response?

Answer: They can work to make their experiments psychologically real to participants, even if experimental procedures or manipulations do not perfectly resemble situations in real life. They can conduct replications with CONCEPTUALLY similar independent variables or with different participants in different settings. They can use cross-cultural research to determine whether there are any human universals. They can conduct field experiments outside the laboratory.
