Disclosed herein is a method of producing a stimulus for electrophysiological assessment of a visual field. The method comprises the steps of: generating a pseudorandom sequence of elements selected from at least two different element types, wherein elements of the sequence are assigned equal time intervals; and displaying the pseudorandom sequence. Each element of a first element type is associated with a baseline value, the baseline value being constant throughout a respective assigned time interval. Each time interval assigned to an element of a second element type is divided into a plurality of portions, each successive portion being associated with a display value of the element, wherein display values associated with, adjacent portions differ from one another, and further wherein display values associated with at least two of the portions are different from the baseline value.
