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
