Nature and Nurture

The video discusses Williams Syndrome, a genetic disorder characterized by a deletion on chromosome 7. Individuals with this syndrome have unique cognitive abilities, such as strong facial recognition skills but weaker spatial vision. Research using fMRI shows that their brains, although smaller, have more areas dedicated to face processing. The discussion explores whether these abilities are due to genetic predispositions or lifelong experiences, highlighting the interaction between nature and nurture in shaping brain functions.

What genetic characteristic is associated with Williams syndrome?

• A mutation on chromosome 15

• A deletion on chromosome 7

• An extra chromosome 21

• An extra chromosome 18

Which cognitive ability is notably strong in individuals with Williams syndrome?

• Face recognition

• Spatial vision

• Mathematical reasoning

• Logical reasoning

What did the fMRI experiments reveal about the brains of individuals with Williams syndrome?

• They have a smaller prefrontal cortex

• Their brains show no difference in face processing regions

• Their brains have more temporal lobe involvement in face processing

• They have larger brains than typical individuals

How does the fusiform gyrus in individuals with Williams syndrome differ from typical individuals?

• It is smaller but more dedicated to face processing

• It is larger and more active in spatial tasks

• It is larger and less specialized

• It is the same size but less active

What is suggested to keep the interest in faces active in individuals with Williams syndrome?

• A lack of interest in other activities

• A specific educational approach

• A genetic predisposition

• An environmental factor
