Perceptual constancy and Set

Question from last lesson
Explain why figure ground should be considered when
using camouflage (2 marks)

In order to develop an effective camouflage, it is important that the
ground (background) characteristics and qualities are taken into
consideration when adjusting the appearance of the figure so that it
becomes part of the ground. In an urban environment, a tiger’s bright
orange stripes are in strong contrast to the monochromatic grey of a
city landscape and the ‘figure’ of the tiger is easily observed against
the ground. In the jungles of India among the yellow, oranges and
brown of the grasses, a tiger disappears, its camouflage seamlessly
blending it into the background.
Award 1 mark for explanation and 1 mark for an application of
effective camouflage

Perceptual constancy refers to the tendency to perceive an
object as remaining stable and unchanging (‘constant’)
despite any changes that may occur to the image cast on the
retina.

Perceptual Set
Perceptual set is the predisposition, or ‘readiness’, to perceive
something in accordance with what we expect it to be. Our
expectations of what an object or event will be make us more
likely to interpret the object or event in the predetermined way.
