visual brain
what is spatial ventriloquism
when visual and auditory stimuli are presented together, the percieved location of sound is often shifted towards visual stimuli
what is temporal ventriloquism
the perceived timing of visual stimuli is biased towards thag if asynchronously presented auditory stimuli
modality appropriateness hypothesis
when different senses give different information we favour the one best suited to the task
maximum likelihood estimation
proposes that the brain forms a weighted average of the estimates obtained from each sensory modality
benefits of multisensory integration
resolves internal and external discrepencies - helps maintain a unified percept of world
increases precision of perceptual judgements
Mcgurk effect
visual lip movements alter the perception on auditory speech
key neural mechanism of multisensory integration
superior colliculus
3 rules of sensory integration in the superior colliculus
temporal rule
spatial rule
inverse effectiveness rule
amount of perceptual learning depends on.....
task difficulty (easy tasks transfer well, hard tasks dont)
does sleep play a critical role in consolidation of learning?
yes! critical time window is less than 30 hours after training on a task
two models of consolidation during sleep
synaptic homeostasis model
reactivation model
