PSYB51H3 Chapter Notes - Chapter 1: Neuroimaging, Electroencephalography
Document Summary
To study this it needs scientific methods: threshold, scaling measuring private experience, signal detection theory measuring difficult decision, sensory neuroscience, neuroimaging an image of the mind. Which left him in the middle of the debate between dualism and materialism: dualism the idea that the mind has an existence separate from the material world of the body, materialism the idea that the only thing that exists is matter, and that all things, including the mind and consciousness, are the results of interaction between bits of matter. Weber asked people to lift one standard weight and one comparison weight that differed from the standard in incremental amounts: found that the ability of a subject to detect the difference between the standard and comparison weights depended greatly on the weight of the standard, he called the difference required for detecting a change in weight the just noticeable difference (jnd) or difference threshold.
