PSYC 100 Chapter Notes - Chapter 4: Subliminal Stimuli, Optic Chiasm, Visual Cortex
Document Summary
Gravity provides cues for people"s judgment concerning the spatial orientation of their bodies. Pioneer in sensation/perception research (binocular vision and human spatial orientation) Used room that tilts sideways and plane that travels in a parabolic manner to experience normal, hypergravity and microgravity environment. Human relies on visual, gravity and body direction. Perception: selection, organization and interpretation of sensory inputs (into something meaningful: psychopyhsics: Study of physical stimulation and how it is translated into psychological experience. The dividing point between the energy levels that have do and do not have a detectable of effect. Absolute threshold: minimum amount of stimulation that an organism can detect. > also defined as: stimulus intensity detected 50% of the time. *under ideal condition, human abilities to detect weak stimuli were greater than previously thought. Jnd: smallest difference in the amount of stimulation that a specific sense can detect (cousin of absolute threshold)
