what is true about improvisational learning?
good continuation
A Gestalt grouping rule stating that two elements will tend to group together if they seem to lie on the same contour.
Backpropagation
A common method of training a neural net in which the initial system output is compared to the desired output, and the system is adjusted until the difference between the two is minimized.
good continuation
A factor in visual grouping; we tend to perceive contours in a way that alters their direction as little as possible.
mental scanning
A process of mental imagery in which a person scans a mental image in his or her mind.
temporal lobe
A region of the cerebral cortex responsible for hearing and language.
parietal lobe
A region of the cerebral cortex whose functions include processing information about touch. responsible for attention and conscious activity
Alan Turing
English mathematician who conceived of the Turing machine and broke German codes during World War II (1912-1954)
distributed knowledge
Information stored via a distributed representation.
modal completion
Surface completing in front of another even though no edge is "seen"
amodal completion
Surfaces completing behind an occluding surface Surface is not seen but is "registered"
visual attention
We automatically pay attention to and recognize basic visual features in an environment, including color, shape, size, orientation, and movement
hemispatial neglect
a failure to attend to stimuli on the opposite side of space to a brain lesion
prototypes
a mental image or best example of a category
Connectionism
a type of information-processing approach that emphasizes the simultaneous activity of numerous interconnected processing units
Canonic view
a viewpoint from which an object can be recognized
concept learning
abstraction of categories from examples
frontal lobe
decision making
individual cellular recording
electrical probes are placed to see what causes neuron to fire
proximulus stimulus
goal of perception to infer properties of the world.
contraleral field
if two corpus collosum is cut, the two shared image information are no longer present.
long-term potentiation
long term change in the degree to which a particular synaptic connection conveys excitation
intension
mental representation of the category.
geometric model of similarity
mental representation of the perceptual features takes the form of a mental space.
single universal model of learning
modification of connection weights based on experience.
induction
not logically certain
perceptual grouping
organization of the raw elements of visual image into larger units, like contours, surfaces, and objects
exemplar models
people may simply remember the examples in a category and compare novel patterns to the examples: examples are used directly
split brain patients
people whose corpus callosum has been surgically severed
deduction
reasoning that is logically certain.
receptive field
sensory stimulation that a cell is sensitive to.
localization of function
specialization of particular brain areas for particular functions brocas patients that had left hemisphere damaged lost power of speech.
object centered coordinate system
tail at rear point of body. implies viewpoint independence.
parallel computation
the application of several computers to one task
biological plausibility
the association agrees with currently accepted understanding of biological and pathological processes
Pragnanz
the overarching Gestalt idea that experience will be organized as meaningful, symmetrical, and simple whenever possible.
apparent motion
there's just an apparent of motion, but our mind sees a motion.
extension
things of the world that part of the category
principle of common fate
things that are moving in the same direction appear to be grouped together
Gestalt Perceptual Organization
this led to a number of gestalt principles.
photoreceptors
variable responses. communicate along dendrites to the later cells which are actual cells.
edge detector
very similar to spot detectors. competing laterally inhibiting the inhibitory area.
occipital lobe
vision
statistical pattern learning
visual pattern examples for blood flow activity
