S07 E05 Atkinson & Hilgard's Perception: When a Tent Becomes a Bear
This episode of CSS Breakdown: Book by Book, Season 07, Episode 05, based on Chapter 5 of Atkinson & Hilgard's Introduction to Psychology 15th Edition, takes you on a journey into the complex world of perception. We begin with a compelling real-life tragedy where hunters mistakenly perceived a tent as a dangerous bear, highlighting that perception is not merely receiving sensory data but an active process of constructing a model of the environment.
Listeners will explore the five fundamental functions of the perceptual system:
• Attention: Discover how your brain selectively focuses on crucial information, explaining phenomena like weapon focus and inattention blindness.
• Localization: Learn how we determine where objects are, including the principles of figure-ground organization, grouping (like by proximity or similarity), and the use of depth cues (both binocular disparity and monocular cues like relative size and perspective). We also examine the perception of motion, including stroboscopic motion.
• Recognition: Unpack how we identify what objects are, from combining primitive features in processes like feature integration theory to the influence of top-down processing and context. Special attention is given to face recognition and why it might be distinct from other object recognition.
• Abstraction: Understand the efficiency of abstracting critical information, allowing the brain to process and store data more quickly than exact representations.
• Perceptual Constancies: Explore the remarkable ability of our minds to maintain stable perceptions of an object's color, brightness, shape, and size despite changing sensory input. You'll also learn how these constancies can lead to intriguing illusions, such as the moon illusion and the Ames room.
The episode also delves into the divisions of labor in the brain for perception, showing how specialized regions handle tasks like localization and recognition, and discusses perceptual development, examining the interplay between innate capacities and environmental experience. Tune in to understand the fascinating mechanisms behind your everyday experience of the world.
