1. Which of the following best describes the Platonic view of vision and the world?
The perception of plato, where our mortal senses are only capable of seeing a small section
of the world. However what we see is still real.
2. Which of the following is the alternative view which is illustrated in the writing of Friedrich
Nietzsche?
View as Construction; “The ‘apparent world’ and the ‘true world’ means – ‘the world’ and,
‘nothing’.
3. The world that we visually sense is entirely dependent upon……
The presence and pattern of light reflected and absorbed.
4. Excitation refers to…….
Something doing something. Application of energy to something. Response to stimulus.
5. Sensation refers to…….
A physical response to perception and stimuli.
6. What do L,M and S denote when applied to cones?
Long (530nm), medium (Green 530nm) or short (Blue 44nm) wavelengths
7. Psychophysics is….
System of measuring behaviour.
8. The crux of the argument between Hering and Helmholtz was…
Opponent theory vs trichromatic theory. Colour was detected by three different receptors of
different peak sensitivity.
9. The spectral sensitivity of the three cone types must overlap because….
10.A colour space is……
11. Your sensation of a particular colour depends upon….
12. The common statement that ‘The brain turns the image the right way up’ is incorrect
because…
13. What is red?
What reason may you have for expecting the photoreceptors to be physically anchored
on the retina despite the observation that this means that there is neural matter
between the light source and the photoreceptor?
2. Opponency confers which of the following properties upon that stage of the system?
3. Which statement best describes a receptive field?
4. What is the most likely format of the first spatially structured (or differentiated) receptive
fields in the visual system?
5. The receptive field arrangement referred to in Question 4 confers what properties to the
system?
6. Why, when considering the processing of the neural signal, is the actual physical
location of any visual neurone other than the photoreceptors, arbitrary?
