AOS 1 Flashcards
IV
the independent variable is the variable being manipulated or controlled by the experimenter
DV
the dependant variable is the variable being tested and measured
EV
extraneous variables arenas variables that could affect the DV that isn’t the IV. extraneous variables reduce validity
hypothesis
a proposed explanation made on the basis of limited evidence as a starting point for investigation
synaesthesia
when neural connections between sense organs are linked so that detection of a stimulus can be interpreted in two senses
perceptual set
when expectations influence a persons perception and sensation
shape constancy
refers to the fact that we can interpret objects when viewed from any angle.
size constancy
refers to the fact that we maintain a constant perception of an objects size even if the object moves nearer or further away.
phi phenomenon
associating cartoon/drawn shapes with things that look similar (cartoon mouse vs real mouse)
figure ground
seeing lines and associating it with an image we have previously seen
camouflage
blends into background
closure
even though an object may be incomplete, we complete it and associate it as a whole. Preferring complete shapes, we automatically fill in gaps between elements to perceive a complete image; so, we see the whole first.
similarity
group together to provide a ‘whole’ single unit. We seek differences and similarities in an image and link similar elements.
proximity
as individual parts are close to each other we tend to perceive them as ‘whole’. We group closer-together elements, separating them from those farther apart.
gestalt principles
phi phenomenon, proximity, similarity, closure, camouflage, figure ground
pictorial depth cues
linear perspective, height in the visual field, interposition, texture gradient, relative size
linear perspective
where two lines go closer together and therefore you think the image is further away
height in the visual field
a higher object appears further away then one below it
interposition
when one object is behind or partially behind another object, it appears further away
