Chapter 3 Flashcards
Process by which our senses gather information and send it to the brain
Sensation
5 Senses
Visual Olfactory Touch Auditory Taste
The concentration of mental activity
Attention
Set of processes (recognize,organize and make sense)
Perception
A mental representation of stimulus that is perceived
Percept
Ability to see the world in three dimensions
Depth perception
Ability to identify the objects in view based
Object Perception
Inability to process sensory information(objects)
Agnosia
Face blindness called
Prosopagnosia
inability to perceive more than a single object
Simultanagnosia
Theories of perception
Bottom up and Top Down
loss of past memory (unable to recall events that occurred before)
retrograde amnesia
loss of memory
amnesia
refers to a decreased ability to retain new information (50 first dates)
anterograde amnesia
the inability of adults to retrieve episodic memories (2-4 years old)
childhood amnesia
loss of speech production
aphasia
deterioration of hippocampus
korsakoff syndrome
closer is in front of other objects
interposition
images seem to be blurry when it is further
aerial perspective
refers to the fact that we perceive depth when we see two parallel lines
linear perspective
3 approaches to human perception
structuralist, gestalt, and constructivist approach
father of structuralism
William Wundt
visual perception defined according to location size intensity
structuralist approach
a whole is more than the sum of its part
gestalt approach
use of contexual info in pattern recognition (top down processing)
constructivist approach
what we see, sense, know and infer
top-down theory
cause varying symptoms throughout the body, including memory impairments, changes in the emotional state, and hallucinations
Disturbance in the temporal region of cortex
objects get smaller at decreasing speed of distance
Motion parallax
individuals organize their experience as simple, concise, symmetrical and complete manner
Law of Pragnanz
the way we determine what part of environment is the figure
Figure-ground
things that are near to each other are GROUPED together
Proximity
objects of SIMILAR shape or color are grouped tend to be perceived as pattern
Similarity
we organized the objects we see by finding CONTINOUS sequences
Continuity
occurs when an object is incomplete or space is not completely enclosed
Closure
symmetrical lines tend to be recognized as shapes rather than lines
Symmetry
first to systematically investigate the figure-ground phenomenon
