Conversion of Field Data in Lab Experiments’

The objective of the present investigate is to examine the visual search method while controlling the factors like reaction time, intelligence, span of attention and experience and to discuss the differences between lab and field experiment and converting field based research to lab based research. It was hypothesized that suitable methodology will overcome the difficulty in transforming the visual search data among lab and field experiments. At first, 25 subjects were randomly selected and assessed on Psychological tests like Progressive Raven Matrix, Attention span and Ishihara colour test. Keeping the controlled situation in view, 15 students were ultimately selected for the experiments. Results revealed that Absolute Threshold of board recognition in lab is at 583.33 ft. whereas in field study it is at 612.5 ft., absolute threshold for green and brown colours is at 475 ft. for both lab and field situations. It disclosed inequitable support of current theory.
