TTC - Sensation, Perception and the Aging Process - Frank Colavita
English | Video 720x480 | E-Learning | 3.90 GB
In 24 fascinating lectures, Professor Francis Colavita offers a biopsychological perspective on the way we humans navigate and react to the world around us in a process that is ever-changing. Our experiences are vastly different today than they were when we were children and our senses and brains were still developing; and those experiences are becoming ever more different as we age, when natural changes alert us to the need to compensate, often in ways that are quite positive.
For example, children have many more taste receptors than adults, so they are more taste sensitive. Therefore it's both ironic and understandable that children often prefer bland food drawn from a small list of favorites to avoid being overwhelmed. Adults, on the other hand, lose taste receptors as they age, so getting older often moves us in the opposite direction, prompting us to try new varieties of ethnic cuisines and spicier foods.
One of the delights of this course is the balance of the real-life examples Professor Colavita gives and the crisp presentation of the physiological systems that explain those examples.
How do our sensory systems gather and process raw information from the world, enabling us to see, hear, smell, taste, or touch How do we keep our balance Or understand exactly where we are in space, so that we can reach for our morning coffee cup and not close our hands around empty space
How do our bodies create motor memories that allow us to learn and then automatically perform the most complex taskssuch as the laboriously practiced elements of a golf swingin one smoothly executed motion, or run through a series of rapid gear shifts while driving on a winding mountain road
What sort of sensory system allows us to feel pain but also works to protect us from its most intense levels
Whether exploring the complex structures of the brain or inner ear, explaining with compassion the animal experiments that have given us so much knowledge of sensory systems, or using humorous personal anecdotes to illustrate a point, Professor Colavita delivers a course that informs, entertains, and even prepares us for the changes that lie ahead.

Sensation, Perception, and the Aging Process
Taught By Professor Francis B. Colavita, Ph.D., University of Indiana,
University of Pittsburgh
Dr. Francis Colavita was Emeritus Associate Professor of Psychology at the University of Pittsburgh, where he taught for more than 40 years.
He also held an adjunct faculty position at Florida Atlantic University.
He earned his B.A. in Experimental Psychology from the University of Maryland and his Ph.D. in Physiological Psychology from the University of Indiana. He went on to complete a two-year postdoctoral research fellowship at the Center for Neural Sciences.
Professor Colavita's teaching excellence was rewarded with five teaching awards, including the prestigious Chancellor's Distinguished Teaching Award. This is the highest award for teaching excellence bestowed by the University of Pittsburgh.
Professor Colavita published more than 30 scholarly articles in the areas of sensory processes, perception, and recovery of function following brain damage. He was the author of the book, Sensory Changes in the Elderly.
Dr. Colavita passed away in early 2009.
