TL;DR
It is shown that single P3 waves associated with signal-absent decisions are shown to have a longer mean latency and a larger latency variability than those associated with sign-present decisions.
Abstract
Abstract Evoked potentials accompanying decisions on signal and nonsignal presentations in a threshold detection task are recorded and analyzed by means of a latency alignment procedure. The results indicate the presence of a distinct P3 wave accompanying both correct signal-present and correct signal-absent decisions. Single P3 waves associated with signal-absent decisions are shown to have a longer mean latency and a larger latency variability than those associated with signal-present decisions. These latency characteristics of the P3 wave appeared to correlate with the level of confidence with which the decision was taken.

Cortical-evoked potentials were recorded from human subjects performing an auditory detection task with confidence rating responses and it was demonstrated that high-confidence false alarms for accompanied by late-positive P3 components equivalent to those for equally confident hits are demonstrated.

Averaged evoked responses to auditory stimuli were obtained in simple reaction time and vigilance tasks, as well as a no response control condition, to reflect different functional roles of sensory evoked potentials and association cortex potentials.

Vertex potentials were recorded from eight Ss performing in an auditory threshold detection task with rating scale responses and it was suggested that the N1 and P3 components represent distinctive aspects of the decision process, with N 1 signifying the quantity of signal information received and P 3 reflecting the certainty of the decisions based upon that information.

It is shown that alertness does not affect the buildup of information within the memory system but only the rate at which a later system responds to that information, and in standard reaction-time tasks, increased alertness produces a reduction in reaction ’time but no decrease in errors.

Although the predictions of the models are similar in many respects, there are some points concerning the ordering of mean latencies, reaction time receiver operating characteristic curves, latency-probability relations, and the constancy of d' which differentiate them.

During the periodic presentation of vibratory stimuli at rates faster than 1 stim/10 sec the amplitude of the cortical evoked response of man decreases as a function of time, and this effective information might result from a comparison between information concerning stimulus parameters stored by the CNS and the actual incoming event.

The S’s decision criterion was found to have an influence on response latency, which was consistent with the hypothesis that stimuli close to the current criterion elicit longer response latencies than stimuli more distant from the criterion.

The contention that the form of the vertex evoked response is closely correlated with the subject's psychophysical decision regarding the presence or absence of a threshold-level signal is strongly supported.
