Sensation and Weber’s Law
Summary
This content delves into the intricacies of sensation and perception, highlighting the differences between these two processes, and explores the principles of sensory adaptation, sensitization, and the Weber-Fechner laws as they relate to sensory processing.
- Sensation is the stimulation of sensory receptors resulting in neural impulses, while perception involves the brain's interpretation of these sensory inputs.
- Sensory adaptation (or habituation) refers to the diminishing perception of a stimulus over time, whereas sensitization is the increased sensitivity to a stimulus, often due to trauma or strong emotional experiences.
- The Absolute Detection Threshold is the minimum intensity at which a stimulus is detectable by an individual, varying across different senses.
- Weber's Law describes a ratio relationship between the initial intensity of a stimulus and the threshold at which a change in intensity is perceivable, known as the Just Noticeable Difference.
- The principles of sensory processing and the Just Noticeable Difference have significant applications in fields such as marketing and consumer behavior.
