Document Summary

Transduction: translation of information about environmental events into neural activity. Must be translated into 2 types(one or the other) neural code: anatomical or temporal. Psychophysics is the study of relation between physical characteristics of stimuli and perceptions they produce. Vision: light, eye and functions, transduction of light by photoreceptors, adaptation to light and dark, eye movements, colour vision. Photopigments: chemicals that transduce light into neural activity in the photoreceptors neurons in the retina. Chemical change in photopigments- ability to see bright or dim light. 3 types of purposive movements, involuntary movement s in the eye. 3 types of cones in retina: sensitive to wavelength of light, and detect colours. Audition: sound, ear and its functions, detecting and localizing sounds in environment, age related losses in hearing. Gustation: receptors and sensory pathway, five qualities of taste. Olfaction: anatomy of olfactory system, dimensions of odour.

Critics of the trichromatic theory of colour vision have indicated that this theory has a major limitation. Which of the following statements MOST accurately reflects this limitation? A) Young and von Helmholtz were incorrect in assuming that cone photoreceptors in our retina are maximally responsive to a specific wavelength of light B) The trichromatic theory cannot explain the phenomenon of visual after-effects C) Rod photoreceptors in our retina, not cones, are responsible for the neural coding of colour D) Research has determined that there are actually six types of cones in the retina, rather than three as proposed by Young and Helmholtz E) Trichromatic theory cannot explain sensory adaptation

5. Dark adaptation A) takes longer for rods B) produces greater sensitivity in the cones than in the rods C) takes longer when moving from an environment of red light to darkness D) is the process by which photoreceptors are depleted of pigment molecules E) only takes 10 minutes for both rods and cones

1. Zachary was born with a rare visual defect. He has no cone photoreceptors in his retina, there are only rods. Assuming that all other aspects of his visual system are normal, which of the following would characterize Zachary's vision? A) poor visual acuity B) an inability to differentiate between black and white C) a difficulty seeing in low light conditions D) colour blindness E) both A) and D)
