APFIVE Physiological Mechanisms of Hunger
A researcher studying hunger in rats removes the stomachs of a group of rats to determine if they still exhibit hunger behaviors. The researcher concludes that stomach contractions are not the sole cause of hunger because the rats continue to show interest in food. What conceptual mistake did the researcher make?
A

B
Ignoring the possibility that the rats’ interest in food was due to learned behaviors rather than hunger.
C
Assuming that the removal of the stomach would not affect the rats’ metabolism.
D
Failing to consider the role of the hypothalamus and hormones in hunger regulation.
