  1. Prospective and Retrospective Perception of Time AshisPati DiwakarAgarwal

  2. Objective: • To study the effect of routine and non-routine nature of the task on time perception • To find out difference in perspective and retrospective time perception in above two conditions.

  3. Experiments performed • Sheet of numbers • Two types of sheets each with 30 rows of digits. Each row consists of 38 randomly generated digits. • In each row a digit is underlined. • Subjects are supposed to count the instances of the underlined digit in the row and write it at the end of the row. • The digits underlined are same in case of routine task while they are different in non-routine task.

  4. Contd.... • Each subject was given a practice time of 20 seconds to practice the task. • After that they were asked to perform the experiment for a fixed duration of 1:30 min(not told to them) • They after the period they were asked to stop and then estimate the time they spent during the experiment. • In perspective test the were told beforehand to keep track of time while doing the task.

  5. Experimental Results (Retrospective)

  6. Experimental Results (Prospective)

  7. Analysis of the Results (Retrospective) • The retrospective time estimation for the routine task was less than that of non-routine task but only by a small amount of 5 seconds. • This difference although small is as expected • The mean of the non-routine task is 63.33 seconds is less than the allotted time of 90 seconds. This is contrary to what is hypothesized. Analysis of the Results (Prospective) • The results for the prospective timing case strongly supported the hypothesis. Average of the routine task was more than the non-routine task as well as actual time. • Few subjects showed behavior strongly in accordance to hypothesis. They guessed a time more than twice the actual time.

  8. Possible sources of Error • The experiments were carried out in our wings with our wing mates as subjects. Errors may have been caused by a possible lack of serious environment • The data currently is far too less for us to draw any conclusions. Some of the observations may be statistical errors • A few of the subjects reported their lack of understanding of the task after the experiment Plan of Action • We plan to conduct this experiment on a class of people in a proper environment with clearer guidelines • We would at least need 40 subjects for each category that a total of 80 subjects

  9. Future Work • To complete the sheet-based experiment with adequate number of subjects in a proper way and analyze the data obtained • To get started on the video-based experiment for which we would also require 80 students in total (40 each for the two categories: prospective and retrospective timing analysis) • Analyze the data obtained from both the experiments and verify the hypothesis proposed in the referred paper.
