Sensation - correct answers is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception - correct answers is the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. Bottom-up processing - correct answers analysis that begins with the sensory receptors and works up to the brains's integration of sensory information. Example: putting a puzzle together...

sensation - how sensory receptors receive and represent stimulus energies from the environment Perception - how we organize and interpret the sensory information, drawing meaning from the world around us neuron - a cell that conducts electrochemical signals and is the basic unit of the nervous system synesthesia - stimulation of one sense triggers another (feeling colors) Interneurons (association neurons) - neurons that carry messages from motor to sensory nerves myelin sheath - prevents ...

PSYC 230 UIUC EXAM 1 QUESTIONS AND CORRECT ANSWERS Signal Dectection Theory a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assume that there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness criterion controlled by the observer d prime The distance between the signal and the external noise + signal. Large d' - increasing the...

just noticeable difference jnd minimum difference in magnitude between two stimuli before one can perceive this difference Weber's law there is a constant ratio between the change in stimulus magnitude needed to produce a jnd (higher stimulus will need a larger difference to produce a jnd) Signal detection theory changes in out perception of the sam stimuli depending on both internal and external context (how loud would someone need to yell your name in a crowd for you to hear their name?...
