Study Notes
Gustav Fechner's Contribution
- Defined psychophysics in his classic work "Elements der Psychophysik" (1860)
Thresholds in Psychophysics
- Absolute threshold: the value of the stimulus above zero at which a sensation takes place
- The term 'threshold' in psychophysics refers to the minimum amount of stimulation required for an observer to detect a stimulus or a change in a stimulus
Classical Psychophysics
- Main focus: to determine the relationship between the physical magnitude of a stimulus and the sensation it produces, according to Fechner, Müller, and Wundt
Psychophysical Methods
- The method of limits gained particular importance among the psychophysical methods explored by Fechner
Explore the history and foundational concepts of psychophysical methods in psychology, including the work of Gustav Fechner, Müller, and Wundt. Learn about the classical psychophysics and the determination of sensory thresholds or limens.
