Interval timing refers to the time perception of hundreds of milliseconds to hours. It involves many activities in daily life and is influenced by many factors, such as arousal, attention and motivation. Pain is a multi-dimensional physiological and psychological phenomenon, including sensory-discriminative, affective-motivational and cognitive-evaluative components. Studies about interval timing in pain context come from three aspects: (1) Time estimation of pain faces in healthy subjects; (2) Time perception of neutral stimuli in healthy subjects under experimental pain or pain expectation; (3) The change of interval timing in patients with clinical pain. Exploring the change of time perception in pain context may provide a new perspective for understanding the mechanism of pain occurrence and development.

Key words: interval timing, facial expression of pain, experimental pain, clinical pain, pacemaker-accumulator model
