- A theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and level of fatigue.
- Diminished sensitivity as a consequence of constant stimulation.
- Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
- The study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them.
- The minimum stimulation needed to detect a particular stimulus 50 percent of the time
4 True/False Questions
Selective Attention → The focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.
Sensation → The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
Weber's Law → Below one's absolute threshold for conscious awareness
Difference Threshold → The minimum difference between two stimuli required for detection 50 percent of the time. We experience the difference threshold as a just noticeable difference. JND
