sensory transduction is the process by which
stimulus are turned into electrical signals and sent into the nervous system
Webers law states that
to be perceived as different, two stimuli must differ by a constant minimum percentage.
Finn and his friends at the beach and Finn goes into freezing water but after a while feels fine, what exapliains this
Sensory adaptation
Which of the following refers to the minimum sitimulation required to detect a particular stimulus
Absolute threshold
Part of eyes responsible for perception of colors
Cone cells help detect color in the Retina
Size of pupil is regulated by contraction and relaxation of which eye structure
Iris
How do we determine a sound wave frequency
Pitch
The idea that cones respond to three primary colors which each type of cone would be most sensitive to a particular rage of light wavelengths is know by this theory
Trichromatic color theory

Fovea
Illusions list them
