Module 3 Flashcards

Coverts stimuli in brain sensations 

Absolute threshold = minimum stimulation needed to register a particular stimulus 50% of the time

Signal detection Theory = a model for predicting how and when a person will detect a weak stimulus, partly based on context 

Difference threshold = point of telling difference between two stimuli

Weber's law = we perceive differences on a logarithmic scale rather than a linear

Chromostereopsis = pure colors at the same distance from the eye appear at different distances 

Amplitude = the amount of energy in a given lightwave

Retina = composed of rods and cones

Parallel processing = ability to process & analyze many aspects of the situation at once 

Retinal disparity = left and right eye view slightly different images

Depth perception = allows us to estimate distances between objects and ourselves

Occlusion = an object that blocks the view of another object must be in front of it

Relative size = smaller objects are farther away

Texture gradient = as texture gets farther away it forms smaller visual angles or pictures on the retina and is less noticeable 

Relative height = objects that appear higher in our visual field are farther away than objects that appear farther 

Familiar size = knowledge of the normal size of certain objects can provide cues to depth 

Linear perspective = parallel lines seem to converge as they move into the distance

Aerial perspective = objects that are farther away also appear to be hazierand bluer

Relative brightness = brighter images are closer and more shaded images are farther away

Proximity = the closer figures are to each other, the more we tend to group them together perceptually

Good continuation = a preference for organization form in a way where contours continue smoothly along their original course

Closure = filling in information to complete perception

Hue = color 

Saturation = intensity of color

Value = how dark or light the color, ranging from black to white 

Monochromatic = different shades of the same color

Analogous = colors next to each other on the color 

Complementary = colors opposite to each other on the color wheel

Split complementary = two colors that are next to a color's complementary color on the color wheel 

Triadic = triangle on the color wheel

Tetradic = rectangle on the color wheel
