Developed a confusion matrix using computer-generated continuous-line uppercase letters. Data were gathered from 20 university students. The letters were presented in 1 of 5 possible positions on the circumference of an imaginary circle at 2.75 deg around the fixation point. The resulting matrix is compared with those of J. T. Townsend (see record 1971-28051-001) and G. C. Gilmore et al (1979) and with D. J. Mewhort and M. L. Dow's analysis of the data of Gilmore et al.
Press a button inserted in the table surface, 500msec after which a letter appeared and the fixation point disappeared. He/she had to respond with a letter name oneach trial.
