Unit 2 Review - Biological Bases of Behavior

This review will guide you through an adaptive, research-backed study session. As you answer questions, we will actively assess your current understanding of the material. Questions will continue to be drawn until you have demonstrated mastery of each learning objective.

Reviews are graded based on completion. You will receive full credit for achieving 100% mastery or answering all questions.

Learning objectives for this review:

Evaluate the interplay between heredity, environment, and evolution in shaping human behavior, focusing on key scientific contributions and the concept of natural selection in psychological traits and behaviors.
Discuss the effect of the endocrine system on behavior.
Describe the structure and function of the nervous system, including its central and peripheral divisions, and explain the role of neurons in the biological bases of behavior.
Identify basic process of transmission of a signal between neurons.
Discuss the effects of drugs on neural firing, including their influence on neurotransmitters through mechanisms like reuptake, and their roles as agonists and antagonists.
Describe the nervous system, including brain subdivisions and regions. Outline the functions of various lobes and cortical areas, and discuss brain lateralization.
Summarize research methods and technologies for studying the brain, such as imaging and lesioning.
Explore neuroplasticity in brain injury recovery, the behavioral effects of psychoactive drugs, and key contributions from researchers like William James and Sigmund Freud.
Discuss the neural and behavioral characteristics of different sleep stages, and explore theories of sleep and dreaming. Analyze symptoms and treatments of common sleep disorders.
