Procedure The tachistoscope should be adjusted so that it gives exposure of about 1/10 of a second. Let the subject be seated comfortably in front of the tachistoscope. make sure that exposed material is clearly visible. Then instruct subject as follows: "when I say ready, you will look attentively at the center of this fixation board. Here, a card containing unrelated letters and small words will appear one at a time for fraction of 1/10 of a second. You have to see the content on the card closely and just after the exposure you have to write this on the response sheet. The reproduced material should be in the same order as presented. Several guards will be shown to you 1 by 1, each time you try to do your best." Now present one card at a time. Cards are to be placed behind the tachistoscope so that they are not visible to the subject beforehand. Uplift the shutter of the tachistoscope and place the appropriate card on the card Holder. Before each presentation, give the ready signal. After 2 seconds, expose the cards placed in the tachistoscope. after each exposure, allow sufficient time to write the presented material. Meanwhile, change the card for the next trial. Between two trials, allow one minute time interval to control the factor of eyestrain. **Procedure** The tachistoscope should be adjusted so that it gives exposure of about 1/10 of a second.
