Document Summary

Sensation is when our sensory organs respond to and translate environmental stimuli into nerve impulses that are then sent to our brain. The perception of characters is also influenced by their context, that is we can the same thing but perceive them differently due to their context: sensory processes. Transduction is the processes whereby the characteristics of a stimulus are converted into nerve impulses example: sharks sense electric currents leaking through the skins of fish hiding in the set. Humans have a range of stimulus detectors. For instance, the sense of touch can subdivided into pressure, pain and temperature. Human sensory systems extract information from the environment on what we need to function and survive. Psychophysics studies the relationship between physical characteristics of stimuli and sensor capabilities. Fechner is the founder of psychophysics and developed the jnd (just time noticeable difference: stimulus detection: the absolute threshold.
