Partner #1 gives one jelly bean of Flavor A
Halfway through chewing Flavor A, #2
unpinches nose and tries to guess flavor.
Repeat for remaining three jelly beans.

3. Perception
Perception
The process of organizing
and interpreting sensory
information.
Selective Attention
The focusing of conscious
awareness on a particular
stimulus.

information.
Selective Attention
The focusing of conscious

16. Perceptual Organization
Visual Capture
Tendency for vision to dominate the other senses.
Grouping
The perceptual tendency to organize stimuli into
coherent groups.
Gestalt
Tendency to integrate pieces of information into a
meaningful whole.
17. Form Perception:
Figure and Ground
The organization of
the visual field into
objects (the figure)
that stand out from
their surroundings (the
ground).
19. Depth Perception
Depth Perception
The ability to see objects in three dimensions.
Allows us to judge distances.
Sources of Depth Perception
Binocular Cues
Monocular Cues

22. Depth Perception:
Binocular Cues
Retinal Disparity
Images from two eyes differ.
The closer the object, the
greater the difference.
Eg MagicEye
Convergence
The extent to which the eyes
converge when looking at an
object.

26. Depth Perception:
Monocular Cues
Interposition - Closer Relative Height –
object blocks distant Objects higher in our
object. vision seem farther.
Relative Size - Smaller Relative Motion – The
image is more distant. nearer an object, the faster
it moves.
Relative Clarity - Hazy
object seen as more Linear Perspective –
distant. Parallel lines seem to
converge at the horizon.
Texture Gradient -
Coarse = close and Fine = Light and Shadow –
distant. Further objects seem more
dim.

28. Motion Perception
As an object moves
across our field of
vision, it is detected by
opposing visual
cortices.
Phi Phenomenon –
marquees.
Stroboscopic
Movement – 24 frames
per second.
38. Perceptual Interpretation
Sensory Deprivation.
There is a critical period
for developing feature
detector cells.
If deprived of a stimuli
over a long period of
time, the brain loses the
original ability to process
that stimuli.
Eg Blakemore and Cooper,
1970.

ESP Telepathy
The controversial claim that Mind-to-mind
perception can occur apart communication.
