Absolute Threshold
minimum stimulation needed to detect a particular stimulus 50% of the time
Difference Threshold
minimum difference between two stimuli required for detection 50% of the time
just noticeable difference (JND)

8. Vision Transduction Wavelength
conversion of one form of energy to another
in sensation, transforming of stimulus energies into neural impulses
Wavelength
the distance from the peak of one wave to the peak of the next

20. Perception
Selective Attention focus of conscious awareness on a particular stimulus
Cocktail party effect

21. Perceptual Organization: Gestalt
Visual Capture
tendency for vision to dominate the other senses
Gestalt--an organized whole
tendency to integrate pieces of information into meaningful wholes

22. Perceptual Organization: Gestalt
Grouping
the perceptual tendency to organize stimuli into coherent groups
Grouping Principles
proximity--group nearby figures together
similarity--group figures that are similar
continuity--perceive continuous patterns
closure--fill in gaps
connectedness--spots, lines, and areas are seen as unit when connected

23. Perceptual Organization
Figure and Ground--organization of the visual field into objects (figures) that stand out from their surroundings (ground)

24. Perceptual Organization
Depth Perception
ability to see objects in three dimensions
allows us to judge distance
Binocular cues
retinal disparity
images from the two eyes differ
closer the object, the larger the disparity
convergence
neuromuscular cue
two eyes move inward for near objects

25. Perceptual Organization: Depth Perception
Visual Cliff

26. Perceptual Organization: Depth Perception
Monocular Cues
relative size
smaller image is more distant
interposition
closer object blocks distant object
relative clarity
hazy object seen as more distant
texture coarse --> close fine --> distant

27. Perceptual Organization: Depth Perception
Interposition

28. If you remove other objects from your field of vision – objects appear to change size.
Looking at a person standing at the end of a tunnel.
Use other data in the environment to judge things.
