The McGurk Effect. The McGurk effect (named after Harry McGurk of McGurk & McDonald, 1976) is a compelling demonstration of how we all use visual speech information. The effect shows that we can't help but integrate visual speech into what we 'hear'. Try the demonstration now, and then read about how the stimuli were made, what the effect means, and how to produce your own McGurk effects. Instructions: You will see and hear a mouth speaking four syllables.
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.
