Illusions Flashcards
What can impact the way someone views illusions
Individual differences such as past experiences and amount of knowledge
What is the bottom-up process for ambigious figures
Neuronal channels, each are sensitive to a particular form of stimulation in particular regions of the visual field
What is visual adaptation
When neurons adapt to the 1 figure (ambitious figure) they weaken do neurons corresponding to the other figure are stronger causing the reversal of perception
Why is visual adaptation good for survival
Allows our vision to adapt fast to changing surroundings
What is the top-down theory for ambitious figures
Objects appear to flip between orientations because the brain develops 2 equally plausible hypothesis and is unable to decide between them
What is the motion after effect
It is when someone perceives Milton when viewing a static stimuli
What is neuronal adaption in motion after effect
It is prolonged viewing of motion in one direction desensitise the observers to motion in that direction such as stationary stimuli appears to move in the opposite direction
Where does motion after effect originate from
The visual cortex - raised from selective adaptation in cells turned to response to the movement direct
WhaT are the different types of MAE
Binocular, monocular and interocular
What happens when you increase the size of a low-contrast stimuli
Increased MAE (spatial summation)
What happens when you increase the size of a high contrast stimuli
Decreased MAE (spatial suppression)
What causes increased MAE (spatial summation)
When a low contrast stimuli increases in size
What causes decreased MAE (Spatial suppression)
A high contrast stimuli being increased
What is central surroundings antagonism
It is a crucial and allows the brain to manage environmental input and avoid info. Overload
Is MAE effected by age
No
