Question

pain cries can usually be differentiated from basic or mad cries by their __________. intensity sudden onset time of occurrence relationship to rem

Explanation:

Pain cries are typically characterized by a sudden onset. Basic cries may be more rhythmic and related to needs like hunger. Mad cries might have a different quality but pain cries often start abruptly due to the sudden experience of pain. Intensity can vary in all types of cries. Time of occurrence is not a key differentiator as pain can happen at any time. Relationship to REM (Rapid - Eye Movement) sleep is more relevant to sleep - related phenomena rather than differentiating pain cries from basic or mad cries.

Answer:

sudden onset
