Abstract
Three response selection methods were evaluated: using a key-controlled cursor to point to the desired option, keying a digit to indicate the desired option, and keying a letter that served as a mnemonic device. The speed and errors of selecting options with the alternative methods were studied as a function of (1) the number of the alternative options in the array and (2) familiarity with the program and the options. Results demonstrated the superiorty of the meaningful letter code, and the differential and lower effectiveness of cursor and digit as a function of level of practice and number of options. A default selection method that utilizes the practice effect is recommended.
