Perfect pitch is the ability to identify a note when it is sounded. In a study of this behavior, perfect pitch was found to predominate in females (24 out of 35 in one group). In one group of seven families, individuals in each family had perfect pitch. In two of those families, the affected individuals included a parent and a child. In another group of three families, three or more members (up to five) of each had perfect pitch, and in all three families, two generations were involved. Given this information, what, if any, conclusions can you draw about whether this behavioral trait might be genetic? How would you test your conclusion? What further evidence would be needed to confirm your conclusion?

- Prairie dogs exhibit a behavior that appears to be contrary to that of natural selection. One will act as a lookout for the others of the community, demonstrating a warning call when observing an eagle flying overhead. This loud noise calls attention to himself which puts him more in harms way than if he ran to hide discretely. However, the warning call allows the others of his community to react and protect themselves. This selfless act is an example of imprinting innate behavior altruistic behavior classical conditioning 500arrow_forwardHow is it possible that we are able to identify correlations between phenotype and some patterns of behavior?arrow_forwardExplain why does only male mice used for testing behavioral studies, why not include the female mice and it is important to use both sex of mice for behavioral studies?arrow_forward
- What does this quote mean? “Whenever you observe a child, you are necessarily observing the child in an environment, not as an isolate.”arrow_forwardThe idea that behavior must be either innate or learned has been called a “nature versus nurture” controversy. What reasons are there for believing that such a strict dichotomy does not exist?arrow_forwardDescribe and give an example of a dominance hierarchy. What role does it play in social behavior? Give a human parallel, and describe its role in human society. Are the two roles similar? Why or why not? Repeat this exercise for territorial behavior in humans and in another animal.arrow_forward
- You were given two examples of learning in class. One related to wasps using landmarks to find nesting sites. The other related to mate choice in birds where the females were exposed to potential mates with artificial crests on their heads. What is the difference in the learning between the two studies? Group of answer choices the wasp study looked at the relatedness among individuals doing the learning both studies demonstrated that the behavior was purely genetic with no learning involved the bird study studied learning and development, permanent changes in behavior as a result of juvenile experience the wasp study studied learning and development, permanent changes in behavior as a result of juvenile experiencearrow_forwardThe table below contains results from an experiment comparing the response time of individuals to an auditory and visual prompt. Compare the results using a t-test and determine if there is a difference between the two tests. If you detected a difference what do you think is responsible for that difference?

- Which form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.arrow_forwardWhat is known about this behavior and neutral mechanisms of this behavior? Include details and experiments performed to demonstrate these aspects.arrow_forwardIs behavior determined only by our genes? This seems a little too absolute, but it is a valid questions. How much of who we are is determined by our genes (I'm including epigenetic parts in this)? There are certain genes that we know are responsible for intelligence, strength, sexuality, and so on. How much is determined by genetics?arrow_forward
