That is because psychophysics quantifies the relationship between physical stimuli and individual perception, building the bridge between the mental world and the material world. This was already a discussion in philosophy, but it was psychophysics that first came with scientific proof of that statement. Secondly, from a philosophical point of view, psychophysics shows that physical reality and psychological reality are not identical. This prepared the field for other studies that would treat psychology as a strict science that should be tested, measured and quantified. So indeed, why is the study of Sensation and Perception important for the understanding of animal and human behavior?įirst of all, there is the more technical and historical side: psychophysics was one of the first fields of psychology to use rigorous methods of study, giving to psychology a very scientific approach rather than a more philosophical one. Wanting to know the relevance of each concept and theory is what all psychology students should seek, considering that psychology is a science that requires a lot of reflection and critical thinking. If upon studying psychophysics you inevitably end up wondering why this is an important part of psychology, you are not being picky. However, these themes are not as difficult as they may sound, and if you still fear psychophysics, read on in this Advanced Placement (AP) Psychology Crash Course Review to clear your doubts and understand what Absolute Threshold, Difference Threshold, and Weber’s Law are all about. This happens especially when weird terms like Absolute Threshold, Difference Threshold, and Weber’s Law come up. Sensation and Perception is possibly one of the less appreciated areas in psychology for the majority of high school and undergrad students because of its resemblance to physics and other hard sciences that commonly scare psychology students away.
