Title: The Biological Bases of Behavior and Sensation Perception in Psychology


The chapters on the biological bases of behavior and sensation perception provide a fundamental understanding of the physiological and psychological mechanisms that shape human experience. This examination will probe the depths of these topics, evaluating students’ ability to comprehend and analyze the complexities of the subject matter. A minimum score of 40 out of 50 points, equivalent to a letter grade of B, will indicate mastery of the principles covered in these chapters. To meet this requirement, students need to exhibit a professional level of understanding in the field of psychology.

The Biological Bases of Behavior:

The first chapter, “The Biological Bases of Behavior,” delves into the intricate relationship between biology and human behavior. It explores how the workings of the nervous system, brain structures, and neurotransmitters contribute to our thoughts, emotions, and actions.

One key topic covered in this chapter is the organization and divisions of the nervous system. Students should be able to identify the two main components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), comprising the nerves and ganglia located outside the CNS. Moreover, they must demonstrate understanding of the subdivisions within the peripheral nervous system, including the somatic and autonomic systems.

A comprehensive understanding of the structure and function of neurons is also crucial. Students should be able to explain the role of dendrites, axons, myelin sheaths, and synapses in the transmission of neural signals. Additionally, knowledge of the action potential process, including depolarization and repolarization, is necessary to fully grasp neural communication.

Furthermore, students should exhibit familiarity with the basic structures and functions of the brain. They should be able to delineate the major brain regions such as the hindbrain, midbrain, and forebrain, as well as their respective functions. Thorough comprehension of the role of key structures such as the cerebral cortex, limbic system, and cerebellum will contribute to a comprehensive understanding of the biological bases of behavior.

Sensation and Perception:

The second chapter, “Sensation and Perception,” investigates the physiological processes underlying how we sense and perceive the world around us. It covers the complexities of sensory receptors, sensory adaptation, and various perceptual processes.

Students should be able to comprehend the different types of sensory receptors and how they transduce sensory information. Additionally, they need to understand the concept of sensory adaptation, which highlights the phenomenon of decreased sensitivity to constant or repetitive stimulation. Exam questions may assess knowledge of specific examples of sensory adaptation in different sensory modalities, such as hearing, vision, and touch.

Furthermore, students should be able to explain the stages of the perceptual process, including sensation, perception, and interpretation. Questions may explore students’ understanding of the differences between bottom-up and top-down processing, and their ability to apply these concepts to real-world scenarios.

Concepts such as absolute threshold, difference threshold, and Weber’s law should also be well understood. A clear comprehension of these concepts enables students to explain the thresholds of sensory perception and the minimal difference required for individuals to detect a change in stimuli.

Finally, a thorough knowledge of the various perceptual phenomena is essential. Students should be able to identify and explain concepts such as binocular and monocular cues in depth perception, the Muller-Lyer illusion, and the Ponzo illusion. These perceptual phenomena challenge our perception of stimuli, and understanding their underlying mechanisms is crucial to analyzing and interpreting sensory information accurately.


This examination covering the chapters on the biological bases of behavior and sensation perception in psychology aims to assess students’ familiarity with these complex topics. A minimum score of 40 out of 50 points, equivalent to a letter grade of B, is required to demonstrate a professional level of understanding. Mastery of the topics outlined in this syllabus will equip students with a strong foundation in the biological and perceptual processes that shape human behavior and experience.
