PSYCH SAC Flashcards
sensation
the process when our sensory organs and receptors detect sensory information
perception
the process where we find something meaningful from the raw information
sensation process
reception - sensory information is first
transduction- the info is converted to into a neural impulse
transmission- the information is sent to the brain for perceptual processing
person is still not consciously aware of sensory stimuli
perception process
interpretation- organised sensory information is understood in a way that depends on the meaning that is assigned to it
organisation- the selected features of sensory stimuli are regrouped so they are cohesively arranged
selection- certain sensory stimuli or features are ignored
the individual is now consciously aware of sensory stimuli
visual perception
the process of becoming consciously aware of visual stimuli as a result of the interaction environments
gustatory perception
the process of becoming consciously aware of flavour. when we chew our saliva breaks down the flavour into tastants
depth cues
visual cues that allows someone to percieve the world in three dimensions and judge the distance and position of objects
monocular
rely on visual information from one eye
accomodation- the ability of the eye to change focus from near to distance objects
motion parallax- the less the objects in our visual field move further, they are away from us
binocular
visual information from both eyes
retinal disparity- our eyes perception produces slightly different images from their different angles
convergence- our eyes muscle strain when we put something close to our eyes
pictorial depth cues
monocular depth cues that allow us to percieve depth/ distance in a two dimensional image
1 ) relative size
2) height in the visual field
3) linear perception
4) interposition
5) texture gradient
gestalt principles
a set of principles that explain how we interpret visual information mostly efficiently by grouping individual elements together
1) proximity- positioned close together
2) figure ground- visual part to be more relevant against the less relevant surroundings
3) closure- to close up and fill gaps in images
4) similarity- visual image that have similar features as belonging together
perceptual set
predisposition to perceive certain features of sensory stimuli and ignore other features that are deemed irrelevant
1) motivation - perception can be influenced by the way a person desire is
2) memory- past experiences may predispose to precieve in a particular way
3) context- refers to the environment or setting that a stimulus is viewed in
psychological influence of gustatory
we percieve gustatory sensation by the shape of our perceptual set
1) appearance/ shape - brain visually receives visual information about the food we before it receives tatse information
2) memory- our past food experiences helps create an expectation of what food taste like based on positive or negative perception
in the sac binocular is and what type of prac relates to it
bioncular is when we rely on visual information with both eyes. In the logbook we used a pen and bought it closer to our eyes which determines the convergence occuring in the prac
