Question

Analyze how psychophysics is applied in coal mining in the 1930s and today?

Answer 1

Psychophysics attempts to quantitatively investigate the relationship between physical stimuli and the sensations and perception that they affect. Fechner had initially coined the term, while making connections between mind and matter. It relates response possibilities to stimulus intensities, tries to make subjective sensation measurable and relate physical and psychological scales. Although psychophysical processes are usually utilized for the measurement of sensation, they can also be applied to any situation in which an accurate assessment of subjective experience is required. One of the examples of today could be how railroad tracks converge visually, even though we know that they are parallel. Historically speaking, a series of psychophysical lifting studies was conducted to establish maximum acceptable weights of lift (MAWL) for three supply items commonly handled in underground coal mines (rock dust bags, ventilation stopping blocks, and crib blocks). These are the different ways in which the discipline impacts various research themes.
