HCI Quiz 1 Flashcards
Quiz 1 scope
mechanism for receiving light and trasmitting it into electrical energy
eye
rods for low-light vision and cones for color vision
retina
detect patterns and movements
ganglion cells
early detection of pattern
x-cells
early detection of movement
y-cells
indicated how much of view object occupies
visual angle
ability to perceive detail
familiar objects perceived as a constant size
cues like overlapping help perception of size and depth
visual acuity
subjective reaction to levels of light
affected by luminance of object
measured by just noticeable difference
brightness
physical characteristic that is measure by a PHOTOMETER
luminance
made up of hue, intensity, satureation
color
spectral wavelength of the light
hue
brightness of the color
intensity
amount of whiteness
saturation
small area of the retina where images are fixated
fovea
it includes saccades and fixation
reading
small movement of the eyes when reading
saccade
small pause on a visual target
fixation
secondary to sight
hearing
protects inner and amplifies sound
outer ear
transmit sound waves as vibration
middle ear
chemical transmitteres are released
inner ear
sound frequency
pitch
amplitude
loudness
type or quality
timbre
provides important feedback about environment
touch
heat and cold
thermoreceptors
pain
nociceptors
pressure
mechanoreceptors
awareness of body posiiton
affects comfort and performance
kinethesis
dependent on age, fitness, and etc.
movement time
dependent on stimulus type
reaction time
descrives the time taken to hit a screen target
fitts’ law
3 TYPES OF MEMORY FUNCTION
sensory memory
short-term memory
long-term memory
UNDER SENSORY MEMOR
ionic memory
echoic memory
haptic memory
visual stimuli
ionic memory
aurals stimui
echoic memory
tactilie stimuli
haptic memory
concentration of mind
atention
serial memory of events
episodic
structured memory of facts, concepts, skills
semantic
child nodes inherit properties of parents nodes
inheritance
contain default, fixed or variabvle infos
frame slots
entry conditions, results, rules, scenes
scripts
must be satisfied condition
entry condition
will be true condition after scripot ended
result
objects involved in the event
props
actions performed by a particular participant
roles
sequences of events that occur
scenes
varaiton on the general pattern to alternative scenario
tracks
infos from STM to LTM
rehersal
amount retained proportionally
total time hypothesis
infost lost gradually but very slowly
decay
new infos replaces/interfer with the old
interference
infos i n memory that is assisted by cues
recall
infos give knowledge
recognition
common cue to recall infos by scene visualization
vivid/imagery
3 TYPES OF REASONING
deductive r.
inductive r.
abductive r.
derive logically necessary conclusion
logical conclusions not necessarily true
deduction
generalize from cases seen to cases unseen
induction
reasoning from event to cause
abductive reasoning
process of finding solution
problem solving
both productive and reproductive
productive shows on insight and restriction of problem
gestalt
skilled activity characterized by chuncking
skil acquisition
right intention, but failed to do it right
cause: poor physical skill, inattention
slips
wrong intention
cause: incorrect understanding
mistakes
emotion = interpretations of a psychological response to a stimuli
james-lange
emotion = psychological response to a stimuli
cannon
emotion = result of evaluation
involves both cognitive and physical response
Schacter-singer
biological response to physical stimuli
affect
“Negative affect can make it harder to do even an easy task; positive affect can make it easier to do difficult tasks”
Donald Norman
