Sensation
is the
perception
of
stimuli
by the
sensory receptors
Transduction
is the conversion of
physical energy
to
neural signals
that can be processed by the
brain
Perception
is the process of taking in information to make it
mean
something
applied
to the
world
Bottom-up Processing
is the process of perception driven by
external stimulus itself
Top-down Processing
is the process of using its
former knowledge
and
expectations
to
interpret new information
The difference between sensation and perception is that sensation is
stimulus
and perception is the
response
Selective Attention
is the process of
focusing
on one thing for a
long
period of time
Inattention blindness
is the failure to
consciously perceive
an
unexpected object
within a
visual field
Change Blindness
in which the person is unable to detect a
change
in the
environment
Selective Attention
affects our
attention span cognitively
Thresholds
are a range of sensory stimuli humans
can detect
Psychophysics
is the study of the relationship between the
physical
and
psychological
properties of stimuli
Absolute thresholds
is the
minimum intensity
required to detect a stimulus
50
% of the time
Signal Detection Theory
is the theory that determines
when
and
how humans react
to
stimuli
"
signals
"
Subliminal
is the stimuli that are
below
the
absolute threshold
,
cannot
be
consciously
identified
Priming
is the process in which the
introduction
of a
stimulus
influences how people
respond
to a
subsequent stimulus
Difference Threshold
is the
smallest amount
of
stimulus
required for us to detect
Weber's Law
is the perception of stimulus
intensity
that grows at a
slower
rate than the
actual
rate of the stimulus
Sensory Adaption
is the
decreased sensitivity
that occurs with
continued exposure
to an
unchanging stimulus
Habituation
is the
decreased
response to
repeated exposure
to a
stimulus
over time, helps identify what poses a
threat
/
harm
Wavelength
is the
distance
between from the
peak
of a wave to the
peak
of the next
Hue
is a
colour
or
shade
that is produced by a
single wavelength
of light
Intensity
is the amount of
energy
in a light or sound wave by a wave's
amplitude
Pupil
is the
black
center of the eye that has a hole for light entry, its size is controlled by iris
Iris
is the
coloured
part of the eye that controls the pupil's
size
, it allows
light entry
Retina
has
rods
and
cones
that has
electrical impulses
for the brain
Accommodation
is the process of lens changing shape to focus on near or distant objects
Rods
detect
low
light,
black
and
white
vision and
peripheral
vision
Cones
detect
colour
and
fine details
, active in
brighter
light
Optic nerve
transmits
visual signals
from the
retina
to the
brain
The
Blind Spot
is the area of the
visual field
that
cannot
be seen by the eye
The
Fovea
is the
central
part of the
retina
where the eye is most
sensitive
to
light
Feature
detectors detect
features
in an image, such as
edges
,
corners
and
lines.
Parallel Processing
is the brains process of different visual
stimuli
qualities, allowing a
quick
response to visual information
Young-Helmholtz trichromatic Theory
is the theory of
three
types of
colour
receptors in
retina
that combines to create a
perception
of every
colour
Opponent-process Theory
is the theory that
colour
vision is based on
opposing retinal
processes (eg.
red-green
,
blue-yellow
,
white-black
)
Afterimage
is the
visual
aftereffect of a
stimulus
not present in the
vision field
Myopia
(
Nearsightedness
) is a
common
refractive error; distant objects appear
blurry
, close objects are seen
clearly
Hyperopia
(
Farsightedness
) is a
refractive
error; distant objects seem
blurry
, distant objects are seen
clearly
Colour blindness
is the
inability
to
distinguish
between certain
colours
