Physiological Mechanisms of Hunger
A researcher finds that rats with their stomachs removed still exhibit hunger behaviors, and therefore concludes that stomach contractions are not the sole cause of hunger. This experimental design, focusing exclusively on the stomach, demonstrates what conceptual oversight?
A
Ignoring the possibility that the rats’ interest in food was due to learned behaviors rather than hunger.
B
Failing to consider the role of the hypothalamus and hormones in hunger regulation.
C
Assuming that the removal of the stomach would not affect the rats’ metabolism.
D
Believing that hunger is solely a physiological response and not influenced by psychological factors.
