Answer:
The answer is emotional focused coping
Step-by-step explanation:
After traumatic events it is common to develop for a period of time what we call emotional focused coping, where the person is lamenting what happened and this is a way they found to deal with their problem.
In this case Martin continues to remember the event three weeks later, due to the seriousness of the event. This is natural since our brains are trained to quickly associate things that are dangerous to us and remember them. It is important to always have means of defending yourself from bad guys. This includes a security system that can handle various alarms and even firearms for immediate self defense. Applying these methods Martin would feel safer and bring an end to his emotional coping.
