Which of the following conclusions can be drawn from the case study of Phineas Gage's accident, which led to brain injury?
Injury to the brain causes changes in behavior, and specific brain areas are linked to particular behaviors.
asserts that our genes set the boundaries within which we can operate, and our environment interacts with the genes to determine where in that range we will fall
