5 Written Questions

1. Below one's absolute threshold for conscious awareness
2. Failing to see visible objects when our attention is directed elsewhere.
3. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.
4. Information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations.
5. The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response.

5 Multiple Choice Questions

1. 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.

3. Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
   1. Bottom-up processing
   2. Priming
   3. Perception
   4. Top-Down Processing
4. The study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them.

4 True/False Questions

1. Selective Attention → The focusing of conscious awareness on a particular stimulus, as in the cocktail party effect.

   True        False

2. Sensation → The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

   True        False

3. Weber's Law → Below one's absolute threshold for conscious awareness

   True        False

4. 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

   True        False
