Salience in the context of temporal processing refers to the ability to identify and prioritize important or relevant information in a given time period or context. In the case of sensory input, salience can be determined by the similarity of waves from different sensory organs, as similar waves are more likely to be perceived as important or relevant. This is known as neural synchronization, which occurs when neurons in different parts of the brain fire in synchrony. This can be thought of as similar waves “joining” or “asserting themselves” to create a more salient signal. This process can also be affected by attention and other cognitive processes, such as if-then planning, which can modulate the P300 and influence the perception of salience.
