Study Notes
Weber's Law
- States that the perception of difference between stimuli depends on a constant proportion.
- This law emphasizes the necessity of proportionate differences for noticeable change in stimuli.
Absolute Threshold
- Refers to the lowest intensity of a stimulus needed for detection 50% of the time.
- Crucial in understanding sensory processing, as it establishes a baseline for detecting sensations.
Difference Threshold (Just Noticeable Difference - JND)
- Defines the smallest detectable difference between two stimuli 50% of the time.
- Important for analyzing perception and how sensory information is compared and differentiated.
Signal Detection Theory
- A framework that explains how individuals discern a stimulus amidst distractions.
- Evaluates both the sensitivity to stimuli and the decision-making processes influencing detection.
