Effect of Conditioned Anxiety Upon the Behavior, Blood Lipid Level, and Atherosclerosis of Cholesterol-Fed Cockerels
Cholesterol-fed cockerels were subjected five days of each week to repetitive unavoidable shocks preceded by warning signals. The birds rapidly developed the intended conditioned emotional reaction. Comparison of these chicks with nonstressed cholesterol-fed cockerels over several months gave no iadication that this type of stress influenced weight gain, blood lipid level, or the development of atherosclerosis.
