Описание: Topic 3 explores the fundamental psychological processes of sensation, perception, and consciousness, detailing how the human body converts environmental energy into meaningful experiences. It describes the biological mechanisms of the five primary senses, highlighting how specialized receptors translate physical stimuli like light and sound into neural signals through transduction. The material further distinguishes between bottom-up processing, which relies on raw data, and top-down processing, which utilizes prior knowledge and expectations to organize sensory input. Beyond physical detection, the sources examine consciousness as a subjective internal state and the various factors that can alter this awareness. Additionally, the content provides practical guidance on identifying sensory thresholds and protecting long-term physical health from environmental hazards like excessive noise.
