What is true about bottom-up processing, according to the provided information?

Bottom-up processing refers to the way our perception starts with sensory input, leading to interpretation. This process is primarily characterized by its reliance on external stimuli, making it a passive process. Sensory data is gathered from the environment, and this raw information is analyzed and constructed into our understanding of what we perceive.

In bottom-up processing, the emphasis is on the information coming directly from the senses without being influenced by prior knowledge, experiences, or expectations. This distinguishes it from top-down processing, which involves using existing knowledge to interpret or influence perception. Therefore, understanding bottom-up processing as a passive intake of sensory data is crucial to grasp the foundational principles of how humans process information from their environment.
