Document Summary
Use durrant text to help for any concepts with which you are having difficulty. A set of methods (and the results obtained using these methods) relating sensation to the physical characteristics of a stimulus. 2 basic approaches: scaling: ordering and distributing stimuli along a perceptual, thresholds: measuring limits of sensitivity (looking for the softest dimension (low pitch to high pitch) word you can repeat back) Ratio estimation: tell subject to estimate based on what categories or observations point. Ratio production: tell subject to turn the dial and make it they hear softer or higher. Direct scaling: physical sounds and how they are perceived: the subject directly establishes the correspondence between, scales help you figure out what"s normal, partition scales. The subject is presented with a range of intensities or frequencies and asked to divide (partition) this range into equally spaced categories on the basis of how he/she perceives them: ratio scales, magnitude scales fractions.
