Validity

About the lecture

In this lecture, we think about validity, focusing in particular on: (i) whether a study is measuring what it explicitly says it is measuring, known as face validity; (ii) whether a study’s results align somewhat with existing results in the same field, known as concurrent validity; (iii) whether the results of an experiment can be applied to the real world, known as ecological validity; (iv) which areas of psychology suffer particularly with ecological validity.
