Question

In its discussion of locus of control, the text cites the British Cohort Study, which followed 11,000 Britons over a period of two decades (Gale et al., 2008). Because the same sample was tracked for an extended time, the study exemplifies the use of a _____ research design in developmental psychology.

Answer 1

Longitudinal

Step-by-step explanation:

In research, a longitudinal research design is a type of design that involves looking at the variables for a long period of time. During this time, observations are made and repeated during the time that the experiment takes place. This way, a longitudinal research design makes comparisons over time.

In this example, the British Cohort Study followed 11,000 britons over a period of two decades. This sample was tracked during these two decades. Therefore, observations on the sample were made during all this time and this exemplifies the use of a longitudinal research design.
