Which processing type is primarily driven by sound input with minimal cognitive processing?

Bottom-up processing is primarily driven by sound input with minimal cognitive processing. This approach focuses on the immediate auditory information received through the ears, analyzing the raw data from sounds and interpreting them without prior knowledge or expectations influencing the understanding. In this model, the perception of sound is built from the smallest units, such as phonemes or syllables, which are then combined to form a coherent auditory experience. As such, bottom-up processing is more about the sensory information and less about drawing on cognitive frameworks or prior experiences as in top-down processing. This makes it especially relevant in contexts where a listener relies on the direct features of auditory signals to make sense of the information presented.
