Question

Quizplus · Accepted Answer

Research conducted over the last 40 years has shown that personality continues to develop and change throughout the lifespan, and is not "set like plaster" by age 30. There is evidence that personality can change in response to life experiences, interventions such as therapy or training, and even as a natural part of the aging process. Therefore, James's claim is not supported by current research.
