UNIT 4: SENSATION AND PERCEPTION Sensation: your window to the world Sensation a process by which our sensory receptors and nervous system receive and represent stimulus (or physical) energy and encode it as neural signals. Our sensory and perceptual processes work together to help us sort out complex processes Bottom-Up Processing analysis that begins with the sense receptors and works up to the brain?s integration of sensory information Top-Down Processing information processing guided by higher-level mental processes as when we construct perceptions drawing on our experience and expectations The Absolute Threshold minimum stimulation needed to detect a particular stimulus 50% of the time. It is the intensity at which we can detect a stimulus half of the time

Doreen Pang Mrs. Trainor AP Psychology 10 October 2016 Module 4-3: How Neurons Communicate: The Neural Chain Specialized cells in the sensory systems of the body Can turn some energy --> action potentials Neural impulses Our brain only uses neural energy to communicate specialised cells that translate outer energy into neural impulse Receptor cells in the eye turn light into a neural impulse the brain understands. Sensory (Afferent) Nerve Carry info. from the sensory receptors to: spinal cord brain A network of cells that take thermal energy and translate into neural impulse Connect the sense organs to the brain and spinal cord. Interneurons Nerve cells in the brain and spinal cord responsible for processing information. Related to sensory input and motor output.
