PSYA01H3 Chapter Notes - Chapter 4: Binding Problem, Haptic Perception, Synesthesia
Document Summary
Your brain (perceptual organ) is transforming those lines & curves into a coherent mental representation of words and concepts. Despite the variety of our senses, they all depend on the process of transduction occurs when many sensors in the body convert physical signals from the environment into encoded neural signals sent to the central nervous system. In vision, light reflected from surfaces provides the eyes w/ info about the shape, color and position of objects. In audition, vibrations cause changes in air pressure that propagate through space to a listener"s ears. In touch, pressure ofa surface against the skins ignals its shape, texture and temp. In taste and smell, molecules dispersed in the air or dissolved in saliva reveal the identity of substances that we may or may not want to eat. In each case, physical energy from the world is converted to neural energy inside the cns. Any type of scientific investigation requires objective measurements.
