Describe an experiment showing how bacteria living in the gut might play a role in processing fear.
To study the control of sex hormones on behavior, researchers may remove an animal’s ovaries or testes and then inject the animal with an estrogen or androgen of interest to see what behavioral effects they have. What advantage does this technique have over another approach, which is simply to measure the concentrations of specific hormones in the blood of animal subjects from time to time?
Fish produce a hormone called isotocin, a hormone that is similar to oxytocin in mammals. Both hormones, oxytocin and isotocin, have been linked to social behaviors including the suppression of social anxiety, trust, and attachment. Prior to this study, the relationship between isotocin in the bloodstream and the amount of aggression or submission individual cichlid fish display was unknown. The researchers hypothesized that isotocin would suppress aggressive behaviors in cichlids to promote social cohesion as these fish exist in large social groups (schools). To address this hypothesis, each of 10 fish were exposed to two treatments, 1 week apart. One at a time, a fish was randomly selected from the group of 10 and either injected with a saline solution (that served as the control) or with isotocin. After this injection, the fish was returned to its group and the amount of aggressive and submissive behaviors the fish demonstrated was recorded for the next 10 minutes. One week later…

- An experiment with squirrels revealed that they make alarm sounds when a model of an owl is placed near them. When a red cube, about the same size as an owl is placed there, there seems to be no alarm. Which of the following best explains this reaction? The owl model is the ultimate cause of alarm vocalization behavior. The owl model, but not the red cube, triggers the fixed action pattern of alarm vocalizations. The squirrel is trying to attract the owl into its territory. The squirrels cannot see red objects, and so do not make alarm sounds. 0000arrow_forwardWhat are the two fundamental types of questions (hypotheses) in animal behavior Group of answer choices When something occurs and how often something occurs is the behavior scary? is the behavior boring? is the behavior related to humans? is the behavior useful?

- Why are human behaviors so difficult to study?arrow_forwardA researcher designed a study to test whether exposure to conflict influences infants’ ability to discriminate emotional expressions. They randomly assigned 30 7-month-old infants to witness an argument between two puppets and 30 additional 7-month-olds to witness the same puppets playing a game. They then used a preferential looking paradigm to test whether infants could discriminate between fearful and angry faces. They found that infants who had witnessed the argument spent more time looking at angry compared to fearful faces. Infants who witnessed play looked at both faces for the same amount of time. This research design is ____________. The experimenters _________ infer that exposure to conflict influenced emotion discrimination. Select one: a. Correlational; can b. Correlational; cannot c.
