PSC 1 Lecture Notes - Lecture 8: Subjective Constancy, Extrasensory Perception, Optical Illusion
Document Summary
Sensation: the detection of physical energy from objects and encoding it as neural signals. Perception: the process by which we organize and interpret sensations: we can never know the world as it truly exists. Transduction: converting the physical energy from objects into nervous system signals that can be sent to the brain. Principles of perception: not everything we sense is perceived. Selective attention: attention is focused on selected events and others are excluded: perceptual processes: integrate and assemble sensory experience. Grouping for simplicity: assembling sensory experiences into meaningful wholes makes them easier to understand: the environment appears organized, consistent, and predictable through perceptual processes. Perceptual constancy: perceiving objects as remaining unchanged despite our changing sensations of them: perceptual processes enable us to judge distance and depth. Interposition: perceptual processes can sometimes distort sensory experience. Perception without sensation : extrasensory perception, thinking fast and slow. Dual-process theory of human thought: system 1. Influenced by emotion and motivation: system 2.
