The biological level of analysis states that there are physiological origins of many behaviors. In order to study this principle‚ several kinds of studies must be utilized. For example‚ animal experiments and postmortem studies are two different kinds of studies used. Two studies that go with each of these are Rosenzweig and Bennett (1972)‚ and Broca (1861) and Wernicke (1874)‚ respectively. All three examples have contributed to the biological level of analysis in each of their own ways. Rosenzweig
