Fallibilty & Distortions of Perception Flashcards
What is an illusion?
A phenomenon in which perceptions consistently differ from objective reality
What is a visual illusion?
A figure structured so that perception will consistently differ from objective reality.
When does visual illusions occur?
When perception consistently differs from objective reality.
What is the ponzo illusion?
An illusion that appears as if the horizontal lines in each diagram are perceived to be longer than the lower horizontal line, as we perceive the depth cues of linear perspective and height in the visual field - both of which make the upper line appear to be further from us.
What is the muller-lyer illusion?
Consists of two lines of equal length, each having opposite-shaped patterns on the ends.
What are two theories that explain the Muller-Lyer illusion?
- the carpentered world hypothesis; it proposes our familiarity with the right angles and straight lines of the built environment informs our interpretation of linear perspective in pictorial depth perception
- the perceptual compromise theory; it proposes that we perceive the line with feather-tails as being longer than the arrow-headed line because our minds apply the Gestalt principle of closure
What is the Ames room illusion?
Shows that we maintain shape constancy at the expense of size constancy.
What is the motion after-effect illusions?
The apparent motion of a stationary stimulus (object) following the extended viewing of a continuously moving stimulus. The stationary stimulus papers to move in the opposite direction.
What is gustation?
Taste
What is olfaction
Smell
What is a perceptual set?
on the fallibility of gustatory perception
Visual cues play a large role in the way we perceive flavour, by allowing us to make predictions about whether or not we should eat something. When we inspect our food, a lot of what we base our expectations on is past experience. From an early age, visual cues such as shape and colour are learned as indicators of a food’s taste or quality, which continues into adult life.
What is a colour intensity?
on the fallibility of gustatory perception
Its the brightness or strength of a
colour can impact our perception of flavour based on our understanding
or experience of which flavours correspond to which colours: the more intense the colour, the more intense the flavour. Playing an important role on our assessment of food and in our prediction of the type of flavour we will experience.
What is a texture?
on the fallibility of gustatory perception
The texture of food can be defined as its physical structure and the way it breaks down in our mouth to release flavour and sensations including size, surface feeling, wetness, and viscosity
What is a synaesthesia?
on the fallibility of gustatory perception
Synaesthesia is an intriguing phenomenon that concerns connections between senses
