Explore the cognitive processes of sensory and perceptual processing, which allow us to detect and interpret stimuli from our environment. Sensory processing starts with our organs converting stimuli into neural signals, while perceptual processing integrates these signals with our knowledge and experiences to form our perception of reality. This includes understanding complex senses like proprioception and nociception, and the subjective nature of perception influenced by individual differences.

Sensory organs detect stimuli and convert them into neural signals through transduction
Processing and Interpretation
The brain processes and interprets the neural signals received from sensory organs
Integration with Previous Knowledge
The brain integrates sensory input with previous knowledge, memories, and expectations
Human sensory perception includes the five classical senses and additional senses such as proprioception, vestibular sense, nociception, and interoception
Perceptual processing involves the interpretation of sensory information, utilizing bottom-up and top-down processing
Individual Biases and Emotions
Perception is shaped by individual biases and emotions, making it a personalized experience
Cultural Backgrounds and Motivations
Perception is also influenced by cultural backgrounds and motivations
Stimulation and Organization
Perceptual processing begins with the reception and organization of sensory stimuli
Interpretation/Evaluation and Memory
The processed information is given meaning and stored in memory
Recall
Memories can be retrieved through recall, sometimes without conscious effort
