Salima and Delia are identical twins who were raised separately – their parents split shortly after the twins were born and Salima was raised by her mother and Delia was raised by her father.

The father moved to Manchester after the split with Delia, but decided to move back to Norfolk when Delia turned 11 so the twins can get to know each other and go to secondary school together. It has been remarked upon that despite growing up in different homes, they both have very similar mannerisms and personalities. At school, however, Salima is outperforming her biological sister in tests and exams and teachers have noticed that she has a greater enthusiasm for learning than her twin.

1. What does the study of twins tell us about the nature vs. nurture debate?
2. What factors may have contributed to Salima having a greater enthusiasm for learning than her twin, Delia?
3. If one of the twins had experienced social disadvantage during the time they were apart, how might this have affected them? Would their personalities still be so very similar?

It is rare that there is just one way to respond to a scenario or situation, so do not consider that the responses you have to the above scenario will be judged as right or wrong. Share your scenario with a work colleague or friend and ask them to tell you whether they think you have responded appropriately. Ask them to challenge your response if necessary. You do not need to submit this task for assessment unless asked to do so by your assessor.
