Abstract : Literature available involving search for simple targets such as alphanumeric data, colors, familiar shapes, etc. was analysed. Relationships were found between search time and the number of non-target stimuli in an array. It was possible to develop that relationship and establish an estimate of scanning capacity (50 elements per second). This is equal to an information transmission capacity of 5.6 bits per second. Other factors also found to be important were the relative emphasis put on speed or accuracy and the dimensionality of the target, i.e., whether it differs from non-target elements in one or more than one ways.
