Psychology 1000 december exam chapter 5 8 study guide. Sensation: stimulus detection, senses translate environmental stimuli into nerve impulses which are sent to the brain. Perception: making sense of what our senses tell us, organizing the stimulus input and giving it meaning, perception is heavily influenced by context. Synesthesia: condition in which the brain mixes up senses (ex. The pruning of neural connections that occurs in infancy hasn"t happened. Insufficient neural inhibition (restriction) in the brain so input overflows to other areas. Psychophysics: the study of the relation between physical stimulus and physiological response. Absolute threshold: lowest intensity at which a stimulus can be detected 50% of the time, varies depending on fatigue, expectations, etc, lower threshold means better sense, signal detection theory: When the perception is more important, people have lower absolute thresholds. Vision (most sensitive), hearing second, others follow.
