  • Sensation and Perception | Growth and Development

    A photograph shows a person staring at a screen that displays one red cross toward the left side and numerous black and white

    This module will provide an overview of how sensory information is received and processed by the nervous system and how that affects our conscious experience of the world. We begin by learning the distinction between sensation and perception. Then we consider the physical properties of light and sound stimuli, along with an overview of the basic structure and function of the major sensory systems. A discussion of a historically important theory of perception called Gestalt is included.

    We will explore the fascinating tale of how you have grown and developed into the person you are today. We also look at some ideas about who you will grow into tomorrow. Yours is a story of lifespan development, from the start of life to the end. (Image Credit: Cory Zanker)
