Cocktail party phenomenon

Embodied
Built into and linked with our cognition
Illusions
Occur when the perceptual processes that normally help us correctly perceive the world around us are fooled by a particular situation so that we see something that does not exist or that is incorrect.
McGurk effect
An effect in which conflicting visual and auditory components of a speech stimulus result in an illusory percept.
Moon illusion
The fact that the moon is perceived to be about 50% larger when it is near the horizon than when it is seen overhead, despite the fact that in both cases the moon is the same size and casts the same size retinal image.
Mueller-Lyer illusion
The line segment in the bottom arrow looks longer to us than the one on the top, even though they are both actually the same length.
Perceptual constancy
The ability to perceive a stimulus as constant despite changes in sensation
Saccades
Quick, simultaneous movements of the eyes
Sensory adaptation
Decrease in sensitivity of a receptor to a stimulus after constant stimulation.
Sensory interaction
The working together of different senses to create experience
Synesthesia
An experience in which one sensation (e.g., hearing a sound) creates experiences in another (e.g., vision).
Dichotic listening
An experimental task in which two messages are presented to different ears.
Divided attention
The ability to flexibly allocate attentional resources between two or more concurrent tasks.
Inattentional blindness
The failure to notice a fully visible object when attention is devoted to something else.
