What is the difference between sensing and perceiving? How does vision actually work? What does this have to do with a Corgi? In this episode of Crash Course Psychology, Hank takes us on a journey through the brain to better explain these and other concepts. Plus, you know, CORGI!

Content Standard(s):
Social Studies
SS2010 (2010)
Grade: 9-12
4 ) Describe the interconnected processes of sensation and perception.

•  Explaining the role of sensory systems in human behavior, including sight, sound, smell, touch, and pain
•  Explaining how what is perceived can be different from what is sensed, including how attention and environmental cues can affect the ability to accurately sense and perceive the world
•  Describing the role of Gestalt principles and concepts in perception

Students know:
  • The basic anatomy of sensory systems.
  • The brain regions responsible for processing sensory information.
Students are able to:
  • Summarize complex concepts in sensation and perception into simpler, but still accurate, terms.
  • Demonstrate phenomena in sensation and perception using multistep procedures and taking precise measurements and analyzing the results compared to information presented in the text or in research.
  • Determine the meanings of terms related to sensation and perception.
  • Associate terms that specifically relate to a particular sensory systems - vision, hearing, taste, touch, smell, kinesthesis, balance, and pain detection.
  • Explain how a situation is sensed and perceived using a particular sensory system and/or interaction of sensory systems.
  • Evaluate how environmental cues impact the processes of sensation and perception.
Students understand that:
  • Sensation and perception are interconnected.
  • Sensory systems work to get information into the brain.
  • Perception is influenced by environmental cues and attention.
  • Gestalt grouping principles and depth cues influence sensation and perception.
