Chapter 4: Sensation and Perception Study Guide ? Absolute Threshold: The minimum stimulus intensity that an organism can detect for a specific type of sensory input. Just Noticeable Difference (JND): The smallest difference in stimulus intensity that a specific sense can detect. The JND is a constant proportion of the size of the initial stimulus. Subliminal: ?Below Threshold? Subliminal Perception: The registration of sensory input without conscious awareness. Signal Detection Theory: The detection of stimuli involves decision processes as well as sensory processes, which are both influenced by a variety of factors besides stimulus intensity. Hits: Detecting signals when they are present. Miss: Failing to detect signals when they are present.

D) nucleotides consisting of a phosphate, sugar, and nitrogenous base 9) Using RNA as a template for protein synthesis instead of translating proteins directly from the DNA is advantageous for the cell because B) RNA acts as an expendable copy of the genetic material, allowing the DNA to serve as a permanent, pristine repository of the genetic material. C) many mRNA molecules can be transcribed from a single gene, increasing the potential rate of gene expression. D) B and C only

SENSATION is the stimulation of sense organs -Sensation involves the absorption of energy, such as light or sound waves, by sensory organs, such as the eyes and ears PERCEPTION is the selection, organization, and interpretation of sensory input -Perception involves organizing and translating sensory input into something meaningful Light is a form of electromagnetic radiation that travels as a wave, moving, natural enough, at the speed of light Amplitude: height of the light wave. Affects perception of brightness Wavelength: distance between peaks. Affects perception of color Purity: How varied the mix is. Influences perception of the saturation, or richness, of colors. Saturation refers to the relative amount of whiteness in a color. As whiteness declines, saturation increases -
