2012 Psychophysics Study Using Optical Slits

Blog

               Over the years, science has given us many ways of studying and exploring vast possibilities. One of those miraculous ways is psychophysics, which is defined as the part of psychology the deals with mental phenomena and physical stimulation. Psychophysics works by studying the specifics of physical stimulation and sensation and looking at the responses produced. In psychophysics, three models of study are most used: the method of constant stimuli, the method of limits, and the method of adjustment. The limits method determines the sensory threshold by increasing or decreasing stimulus level gradually. The method of adjustment is, as it sounds, studying the patient’s adjustment to stimulus levels. These are just some examples of what psychophysics can do. Young’s double-slit formula is another physics example using light that studies and displays light particles’ characteristics and defines light waves.

               In a 2012 study, the double-slit experiment was used in about 25 people to record their individual reactions to stimulus. With the initially planned analysis, there was no psychophysical effect found on the subjects. However, as the study notes, there may be causal links found with more detailed analyses.

               At Lenox Laser, we offer various optical products that are probably built in many ways that use the ideas of psychophysics. We have everything from apertures to slits to pinhole photography, gas and liquid separators, particle counters, molecular beam masks, and more. To see our product line, please visit us here and explore our many variations and possibilities.

               It will be interesting to see just how far the evolution of psychophysics will go, along with the uses of Young’s double-slit experiment. Science never stops evolving, and neither should our eagerness to learn all that we can for future endeavors. That curiosity could make the future even brighter.
