TY - JOUR AU - Pay, B. E. AB - PATTERN DISPLAY UNIT APPARATUS -4 DISPLAY UNIT FOR COMPUTER GENERATED PATTERNS BY B. E. PAY From the National Physical Laboratory, Teddimgton, Middlesex A system is described whereby computer generated two dimensional patterns, stored on punched paper tape, can be displayed on an oscilloscope at high speed. Using computers to generate visual and auditory displays for psychological experiments is well known, White (1962) having reviewed much of this work. One of the most dramatic is that of Julesz (1960) who was able to show many novel features of stereoscopic perception using large fields of randomly distributed data. Such types of display are very difficult to prepare manually. Another example where preparation difficulties can arise is that involving pattern discrimination. Here, the subject(s) may be required to identify, or match, large numbers of relatively simple patterns (Fitts and Leonard, 1957). It is relatively easy to programme a computer to prepare such material and also to present the material and analyse the results. The programme parameters may, in some cases, be an indirect representation of certain hypotheses under test. Such a concrete expression necessarily leads to a greater precision of psychological theorizing or modelling.
