Description
Summary:The paradigm followed in experiments on human vigilance is discussed in detail to show relationships between vigilance, signal-detection, and animal discrimination experiments. Parts of the paradigm involve ‘observing response’ and ‘decision whether stimulus is signal’ as hypothetical constructs, and suggestions from the literature on electroencephalography are developed to convert these to empirical constructs. Specifically, an early potential (100–200 msec latency) of the averaged evoked response may correspond to the observing response, and a late potential (350–600 msec latency) may be related to the way the observer decides whether or not a stimulus isa signal.
