Two experiments investigating. the effects of chronic vs. acute insulin-induced hypoglycemia on attack and biting behavior elicited by tailshock are reported. Chronic-injection subjects had blood-sugar level experimentally reduced by insulin for 29 days, including the day of shock testing. Acute-injection subjects received an insulin injection only on the day of testing. High levels of attack and biting behavior were shown in the single-animal shock-elicited aggression situation by the chronic subjects in both experiments. High response levels were shown by the acute-injection subjects only in Experiment 2. The lack of such responding in Experiment 1 was attributed to the different injection procedures used in the two experiments. The data are supportive of the proposed negative relationship between hypoglycemia and aggressive responding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
