Nevertheless, the study of conscious accompaniments in the context of reaction time was an important historical development in the late 1800s and early 1900s. For example, Wundt and his associate Oswald Külpe often studied reaction time by asking participants to describe the conscious process that occurred during performance on such tasks. [8]
In 2000, T. E. Roswarski and Robert Proctor conducted a variation of the original Fitts and Seeger experiment involving auditory tones in each ear instead of lights. The experiment showed that the reaction time for auditory signals is also influenced by S-R compatibility. [5]
The P300 response of different healthy subjects in a two-tone auditory oddball paradigm. The plots show the average response to oddball (red) and standard (blue) trials and their difference (black). From Surprise response as a probe for compressed memory states . [ 2 ]
Stimulus onset asynchrony, the time that lapses between the presentations of the two stimuli, acts as the independent variable in this paradigm, and the reaction time to the second stimulus acts as the dependent variable. [1] Figure 1. Model of the central bottleneck accounting for the psychological refractory period.
Halkiopoulos demonstrated attentional biases by measuring reaction times to auditory probes following neutral and emotional words in the attended and the unattended channels. This method was subsequently used in the visual modality by MacLeod, Mathews and Tata (1986) in what came to be known as the dot probe paradigm.
Simple reaction time correlates with general cognitive ability, [4] and there is some evidence that the slope of responding on the Jensen box does as well. [2] Ian Deary and colleagues, in a population-based cohort study of 900 individuals, demonstrated correlations between IQ and simple choice RTs between –0.3 and –0.5. [ 4 ]

Increase latency with increase in non-targets. Related to auditory processing duration. [4] Latency related to timing of mental access to properties of a stimulus. Latency related to reaction time. Amplitude: Related to sensory auditory memory traces. Larger for non-targets with no behavioral response. Sometimes called the 'no-go N2'. Larger ...
