Earlier, a forensic psychiatrist, Dr. Merryll Vorster, testified that Pistorius had General Anxiety Disorder (GAD), a chronic condition that causes fear and worry.
Defense lawyers could use her testimony to bolster their claim that the runner's shooting of girlfriend Reeva Steenkamp last year was accidental. The athlete says he thought he was shooting at an intruder when he fired shots through a closed bathroom door in his home.
Prosecutors argue Pistorius shot Steenkamp intentionally after a heated argument.
If convicted, the athlete could face life in prison.
Pistorius is known as the "blade runner" for his carbon-fiber prosthetic legs. In 2012, he became the first double amputee to compete in the Olympics.
