Q

minimalna ilość różnic pomiędzy dwoma bodźcami (aby mogły zostać zauważone przez człowieka)

A

difference threshold - THE DIFFERENCE between TWO stimuli required for detection 50% of the time

‘just the noticible difference’

for example:
The smallest difference in sound for us to perceive a change in the radio’s volume
The minimum difference in weight for us to perceive a change between two piles of sand
The minimum difference of light intensity for us to perceive a difference between two light bulbs
The smallest difference of quantity of salt in a soup for us to perceive a difference in taste
The minimum difference of quantity of perfume for us to perceive a difference in something’s smell

Q

top-down processing

A

guided by experience and higher-level processes we see what we excpect to see

as an experienced hiker you expect to see snakes on your hike, so when you see stick or lizard it all seems at first like snake

Q

what are the two chemical senses?

A

taste (gustation) - taste buds on your tongue (over 200), each containss a pore that catches food chemicals

smell (olfaction) - we smell something when molecules of a substance carried in the air reach a tiny cluster of receptor cells at the top of each nasal cavity

Q

5 basic tastes

A

sweet - indicates energy source
salty - indicates sodium essential to physiological processes
sour - indicates potentially toxic acid
bitter - indicates potential poisons
umami - indicates proteins to grow and repair tissue

tastes exist for more than our pleasure!

Q

zmysł kinestetyczny

A

kinesthetic sense - position and motion detectors in muscles tendons (ścięgna) and joints (stawy) sense the position and movement of body parts

24
Q

zmysł równowagi

A

vestibular sense - fluid-filled semicircular canals and a pair of calcium crystal-filler vestibular sacs located in the ears monitors the head’s (and body) movement

25
interakcja sensoryczna
sensory interaction - our sense can influence each other; -smell impacts taste (when u have old it tastes bland cuz u cant smell it) -we dont feel the taste if he close our nose -we can hear soft sounds better if paired with a visual clue
26
poznanie ucieleśnione
embodied cognition - influence of bodily sensations, gestures and other states on cognitive preferences and judgments np. after holding warm drink people were more likely to rate someone more warmly, feel closer to them and behave more generously
27
synestezja
synesthesia - two or more senses become joined, stimulation of one sense (np. hearing) triggers experience of another (np. seeing color)
28
zestaw percepcyjny?
perceptual set - mental predisposition to perceive one thing and not another, we see what we expect to see obrazek ze stara i młodą babą, jeden zobaczy starą, drugi młodą
29
selektywna nieuwaga
at level of conscious awareness we are in only place at time so we midd salient (wyraziste) objects that are available to be sensed
30
pozauwagowa ślepota
inattentional blindness - failing to see visible objetcs when our attention or focus is directed elsewhere
31
ślepota zmian? nieumiejętność zauważenia zmian
change blindness - failing to notice changes in the visual environment
32
bodziec podprogowy
subliminal stimuli - not detectable 50% of the time, below absolute threshold
33
adaptacja sensoryczna
sensory adaptation - diminished sensitivity to stimuli as a consequence of constant stimulation, once we notice and evalute stimuli as non-threatening we can pay less attention to it, possibly adaptation for survival np. zlew smierdzi i inni to czuja, ale ty sie juz przyzwyczailes i masz wyjebane i nie czujesz
34
GESTALT PSYCHOLOGY
gestalt - 'form'/'whole'; in perception the whole may exceed the sum of its parts; our brain does more than register information about the world we filterincoming information and construct perception, mind matters.
35
Gestalt laws
proximity - we tend to group nearby objects together continuity - we perceive smooth, continuous patters instead of discontinuous ones closure - we fill in gaps to create a complete whole object similarity figure/ground symmetry & order
36
orientacja przestrzenna
depth perception - ability to see objects in 3 dimensions although the images that strike retina are 2-dimensional, allowing us to judge distance
37
visual cliff
model of a clif with 'drop-off' area that was acutally covered by sturdy glass experiment with children indicates that they could perceive depth, cuz they didnt wanna fall from fake cliff
38
dwuoczne wskaźniki głębi?
binocular cues - depth cues such as retinal disparity (dysproporcja) and converge, that depend on the use of two eyes as the object becomes closer or further both binocular depth cues operate to help us judge a distance
39
rozbieżność siatkówki?
retinal disparity (palce po obu stronach nosa i widzimy jak się łączą) by comparing retinal images from the two eyes the brain computes distance, the greater the disparity between two objects the closer the object
40
percepcja głębokości - wskazówki jednooczne
depth perception monocular clues linear perception - parallel lines appear to meet in the distance, the sharper the angle od converage the greater distance is perceived size constancy overlapping shadowing texture gradient
41
iluzje wzrokowe
visual illusions - occur when the principles of perception cause us to interpret visual input incorrectly, tricking the eye
42
nerw wzrokowy
optic nerve - carries neural impulses from retina to the occipital nerve of the brain
43
ucho wewnętrzne
inner Ear - When the stapes moves, it pushes the oval window, which then moves the cochlea. The cochlea takes the fluid vibration of sounds from the surrounding semicircular ducts and translates them into signals that are sent to the brain by nerves like the vestibular nerve and cochlear nerve
44
ślimak
cochlea - a small, curled tube in the inner ear. The cochlea is filled with liquid, which is set into motion, like a wave, when the ossicles vibrate. Vibrations (sound) cause tiny hairs on the cells to move, creating nerve signals that the brain understands as sound
45
ucho zewnętrzne
outer ear - part of the ear collects sound and funnels that sound into the middle ear. Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum
46
przewód słuchowy
ear canal - directs the sound to the middle ear. It’s located between our floppy ears and our ear drum
47
małżowina uszna
pinna - the part of the ear that people can see. The main job of the outer ear is to collect sounds, whether they're your friend's whispers or a barking dog
48
nerw słuchowy
auditory nerve - carries neural impulses from the cochlea to the brain
49
ucho środkowe
middle ear - consists of an air-filled space between the tympanic membrane(ear drum) and the inner ear that contains three tiny bones linked together causes the eardrum and ossicles in the middle ear to vibrate. As it travels, it amplifies (becomes louder) and changes from air to liquid
50
kowadełko
anvil (incus) - tiny bone that passes vibrations from the hammer to the stirrup
51
młoteczek
hammer - (malleus) - tiny bone that passes vibrations from eardrum to he anvil
52
strzemiączko
stirrup (stapes) - tiny u-shaped bone that passes vibrations from the stirrup to the cochlea, the smallest bone in human body
53
bębenek
ear drum (tympanic membrane) - thin membrane located at the end of the ear that vibrates when sound waves reach it
54
the way of sound
eardrum -> hammer -> anvil --> stirrup -> cochlea (EJ HOLA A SIANO CZEKA?)
55
stroop effect
delay in reaction time between congruent and incongruent stimuli nazwy kolorów w innych kolorach i mówienie jakiego są koloru
