PP‐T‐0014‐0‐I The development of digital techniques has enabled the psychophysiologist to extend the range and complexity of his experiments. The functioning of digital devices can be divided into four aspects, namely: 1) data acquisition, 2) data storage, 3) data analysis, and 4) data output. The principles underlying these techniques are outlined, the most fundamental step being the conversion of the analog signal to the digital value. Digital instruments in psychophysiology are reviewed including the data logger, the instrumentation‐coupler, the special purpose computer, and the general purpose laboratory computer. The authors' experience with laboratory computers is described and the great flexibility of these devices in psychophysiological research is stressed.
