Document Summary

Sensation process of detecting stimuli; organs turn stimuli into neural signals. Doctrine of specific nerve energies the idea that different senses are separated in the brain first proposed by johannes muller. Absolute threshold the minimum amount of energy/stimulus required for it to be detected. Difference threshold the smallest difference between stimuli that can be detected 50% of the time. Signal detection theory certainty of whether a stimuli is perceived depends on both sensory experience and judgement made by the subject (ex. walking home after funny movie vs. walking home after a scary movie) Gesalt psychology the whole is greater than the sum of the parts . Figures stand out against their background; which is the figure and which do you pay attention to? a. ) Weight needs to change by one 50th at least every time to be felt proportionally. Sensory adaptation unchanging stimuli are not detected: if something starts changing then it could be important.
