T or F. Top-down processing is primarily attuned to detecting edges of large shapes. |
False |
|
Bottom-up Processing |
- Relies on low level feature processing to build patterns, and recognize objects. - ex: toddler and dog, car, and meeting - Picks up on edges, differences in color, motion, and depth cues. |
|
the "Door Study" |
Showed that people don't notice changes outside their field of attention. |
|
Top-Down processing is good for : |
Goal-directed tasks/ eye movements |
|
Visual Perception is: |
Processes that govern response to visual stimuli |
|
name three things that call for a sense of goal-driected eye movements. |
word search puzzle, menu, map. |
|
T or F. Foveal Vision helps us navigate through space quickly, without banging into things. |
FALSE |
|
T or F. Peripheral vision is used for reading |
False
|
|
A fixation is... |
An act of visual attention focused on a specific object. |
|
A saccade is... |
The rapid movement of the eye from one object of interest to another. |
|
About how many objects can our visual working memory hold in attention to any one time? |
Three |
|
T or F. Spacial grouping can be used to create pop-out |
True |
|
T or F. The anatomy of our visual system is designed to detect what is abnormal or novel. |
True |
|
T or F. everyone has essentially the same visual perception. |
False |
|
What are 3 of the most effective pre-attentive Feature Channels? |
Motion, Shape, Color |
|
Visual Perception is ... |
Processes that govern response to visual stimuli |
|
Our retinas are... |
Essentially 2d but curved. |
|
How many levels of variation are optimal in each feature channel? |
3 |
|
T or F. The absence of pre-attentive feature is easier to detect than its presence. |
False |
|
The "What" pathway |
Closely related to Bottom-up processing |
|
The "Where" Pathway |
- Closely related to top-down processing - uses rapid saccades to identify the next item of interest, based on memory, peripheral vision, and active searches. |
|
Pre-attentive Feature Channels |
Can be used by designers in the planning of eye movement. |
|
New Model of Vision |
Theorizes that evolution has biased our systems toward efficiency |
|
Old Model of Vision |
Suggests we record everything we see then recall it later from memory. |
|
"Just in time" processing |
Links Perception and action closely. |
|
T or F. Color is more fundamental to feature and pattern than is tone. |
False |
|
T or F. Humans can pre-attentively detect up to 3 feature channels, among multiple objects, at the same time, using the pop-out effect. |
False |
|
The Xbox 360 controller works well because the buttons use... |
each symbol differs from the others on several feature channels. (color, size, spatial grouping, and stereoscopic and tonal depth cues). |
|
in figure/ground compositions |
- the positive and negative roles should be nearly equal. - Multiple readings create interest - the shape of the negative space is as important as the shape of the positive space. - the active and passive areas need not be black and white. |
|
Good Gestalt |
By eliminating visual info that our minds are free to create meaning |
|
Law of Continuity |
- Predicts Preference for continuous figures - Intersects - if objects are aligned, we see them as a whole. |
|
Law of Proximity |
- when objects are spaced in a uniform way, we perceive them as a group. - spacial or temporal proximity of element may induce mind to perceive a continuity - (temporal=time) |
|
Law of similarity |
- if objects are similar, we see them as groups. - form, color, size, orientation, brightness, tone. |
|
Law of Closure |
- positive/negative space - we see objects as a whole, even when they are incomplete. - if part of an image is missing, we fill in the gaps. |
|
Law of Symmetry |
- We see objects as a symmetrical form when around a center point. - When 2 symmetrical elements are unconnected, the mind connects them to make a coherent shape. |
|
Law of Common Fate |
-Objects are perceived as lines that move along the smoothest path. - elements with same moving direction are perceived as a collective or unit. |
|
Law of Past Experience (isomorphism) |
- if objects are under some circumstances, categorized among past experience they are perceived together. - grouped together/ close proximity. |
|
we tend to organize our visual experience in a manner that is ... |
regular, symmetric and simple. |
|
T or F. The overall principle of Gestalt asserts that the sum of the parts is greater than the whole. |
False |
|
Optical illusions can be |
Physiological or cognitive in nature. |
|
Physiological illusions |
Based on low level artifacts of visual input or processing hardware or "noise" in the system. |
|
Cognitive Illusions |
- The gestalt principles - our desire to make sense of sensory input. |
|
The key parts of contour boundaries for the perception of objects are... |
Wherever the contours make a sharp change in direction. |
|
T or F. Proximity plays a little part in typographic layout design. |
False |
|
In tasks which involve matching, we can compare features, one by one, or try comparing the overall ......... |
Gestalt |
|
Color coding in maps and data visualizations relies on which of these Gestalt Principles |
Law of Similarity |
|
In both McKim's essay on Visual Thinking and Gestalt, pattern is defined as |
Perceived Organization |
|
Visual experience involves...... |
The integration of vision, cognitive and behavioral phenomena. |
|
Pattern completion involves _______ of the mind and eye |
The custructive activity |
|
Determining the direction of rotation in a drawing representing several connected belts and pulleys... |
uses kinesthetic thinking |
|
pattern finding permits the viewer to... |
See the whole and not just the sum of the parts. |
|
The solution to the "rotating dice problem" describes my Mckim requires an operation simlar to the orthographic imagination, involving.... |
the ability to imagine how a solid object looks from several directions. |
|
Humans are better at visual pattern recognition than computers because |
Humans are capable of quickly scanning images as a whole, instead of checking every detail. |
|
Which one of the gestalt laws helps us the most when imagining and filling-in partially completed patterns? |
Law of closure |
|
