Internal Clock Theory

The Internal Clock Theory suggests that our brains have an internal timekeeping system that helps us judge the passage of time. This "internal clock" generates signals or pulses, and our perception of how much time has passed depends on counting these signals. When this clock runs faster or slower, our sense of time speeds up or slows down. For example, under stress or in new situations, the internal clock may speed up, making time seem to pass quickly; in contrast, during monotonous tasks, it may slow down, making time seem to drag.
