Speech and Language Perception
10: Speech and Language Perception

In this fascinating lecture, discover how you produce and perceive language. Explore how you communicate ideas using basic sounds; how you determine where one word ends and another begins; how things you think are being perceived by your ears are actually sensed by your eyes, and more....

Touch-Temperature, Vibration, and Pressure
11: Touch-Temperature, Vibration, and Pressure

Broaden your understanding of just how detailed and intricate is your sense of touch. You'll spend time considering the different reception systems embedded in your skin; the ways you use touch to control your actions and to explore your surroundings; and how this particular sense grounds your other senses....

34 min
Pain-How It Works for You
12: Pain-How It Works for You

Pain is more than just a nuisance-it's extremely important to your well-being. Get an overview of the systems of pain perception; the ways your brain processes pain formation; how seeing pain in others can quite literally cause you to feel pain yourself; and what happens when the pain system breaks down....

28 min
Perception in Action
13: Perception in Action

Recent scientific studies have shown that your actions can actually control your perceptions. Here, Professor Vishton guides you through our latest understanding of the interplay between action and perception. By looking at how perception and action go together, you'll have a much more accurate grasp of the entire human sensory process....

31 min
Attention and Perception
14: Attention and Perception

Examine how attention works in the human visual system. You'll learn how attention functions, how it enables you to locate mental resources effectively, how it works as a "spotlight" highlighting aspects of visual input, and how it serves as "perceptual glue" pulling together aspects of a stimulus into perceptual objects....

29 min
Kinesthetic Perception
15: Kinesthetic Perception

One human sense often left off the standard list of five: kinesthetic perception, or how you perceive and move your body. Consider aspects of kinesthetic perception, including your vestibular sense (how you perceive the position of your whole body) and proprioception (how you perceive the position of individual body parts)....

28 min
Seeing, Remembering, Inferring Infants
16: Seeing, Remembering, Inferring Infants

Get a better understanding of adult perception by exploring the intriguing process of perceptual development from birth to the first few years of life. How do infants see? Control their eye moments? Use their sensory input to make inferences about things they can't directly see? Learn all this and more here....

29 min
How Infants Sense and Act On Their World
17: How Infants Sense and Act On Their World

Continue building on ideas about how infant perception works and develops. In this lecture, you'll focus on how an infant's nonvisual senses develop; how an infant connects sensory abilities to actions such as crawling, reaching, and grasping; and how these action abilities influence an infant's sensory and perceptual abilities....

Illusions and Magic
18: Illusions and Magic

Enter the world of illusions and see how, in addition to being entertaining, they can reinforce and further develop your grasp of human sensation and perception.

Perceiving Emotion in Others and Ourselves
19: Perceiving Emotion in Others and Ourselves

Sensing the Thoughts of Others-ESP
20: Sensing the Thoughts of Others-ESP

Reading minds. Detecting lies. Predicting the future. Debunk these and other "paranormal phenomena" by exploring how we infer others' thoughts and actions through standard perception.

Synesthesia-Tasting Color and Seeing Sound
22: Synesthesia-Tasting Color and Seeing Sound
