The McGurk effect is a perceptual phenomenon which demonstrates an interaction between hearing and vision in speech perception. It suggests that speech perception is multimodal, that is, that it involves information from more than one sensory modality. The McGurk effect is sometimes called the McGurk-MacDonald effect. It was first described in a paper by McGurk and MacDonald (1976). This effect may be experienced when a video of one phoneme's production is dubbed with a sound-recording of a different phoneme being spoken.
The founder effect is a special case of genetic drift, occurring when a small group in a population splinters off from the original population and forms a new one.s a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species.
