A study was made of the effects of multiple visual masking upon variations in mask position, word frequency, and display on time. Ten subjects were shown five-letter words, four or five letters of which were immediately masked. These words, half of which were classified as frequent and the other half as infrequent, were displayed at different display on times. Results showed that (1) exposing a little information produces the same or better results than not exposing any, (2) variations in the position of the mask cause no increase in visual performance, and (3) in total masking one position shows no better results than any other. Findings indicated both word frequency and display on time are highly significant factors, whereas the masking position is not. Results warrant a parallel processing interpretation, rather than a serial one.
