Which of the following is NOT a requirement for recovery in cases of negligent infliction of emotional distress?

In cases of negligent infliction of emotional distress, one of the traditional requirements is that the plaintiff must have some form of physical manifestation of the emotional distress experienced. This could include physical symptoms resulting from the emotional harm, such as headaches, stomach issues, or other stress-related illnesses. However, there are jurisdictions that recognize that emotional distress can stand alone, especially if the emotional harm is particularly severe or sustained.

The other requirements listed typically align with established standards for recovering damages in negligent infliction of emotional distress cases. Being a family member of the directly affected person is often vital as it establishes a close personal relationship, which courts generally consider when assessing claims of emotional distress. Contemporaneous perception of the event refers to the requirement that the plaintiff must witness the event causing the distress, which helps ensure that the emotional impact is directly linked to a traumatic event. Finally, having a close relationship with the victim further underlines one's emotional stake in the outcome and the ensuing distress.

Thus, while experiencing physical symptoms can be a factor in many cases, it is not universally required for all claims of negligent infliction of emotional distress, making it the correct choice for this question.
