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]
The reaction time increased by as much as 30%. [4] However, what is usually seen as the first genuine demonstration of the effect that became known as the Simon effect is by Simon & Rudell (1967). [5] Here, they had participants respond to the words "left" and "right" that were randomly presented to the left or right ear.
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
As an example, the participant's task might be to indicate whether a visually presented number is smaller or larger than five, [33] such that the left-hand key is pressed for numbers "1" to "4" and the right-hand key is pressed for numbers "6" to "9". Based on the instruction, action triggers are set up that automatically elicit the response ...
RT = trial completion time P = trial number, starting from 1 (for exponential functions the P-1 argument is used) a, b, and c, are constants. Practice effects are also influenced by latency. Anderson, Fincham, and Douglass looked at the relationship between practice and latency and people's ability to retain what they learned.

Serial reaction time (SRT) is a commonly used parameter in the measurement of unconscious learning processes. [1] This parameter is operationalised through a SRT task, in which participants are asked to repeatedly respond to a fixed set of stimuli in which each cue signals that a particular response (i.e., button press) needs to be made.
Inspection time refers to the exposure duration required for a human subject to reliably identify a simple stimulus. Typically a stimulus made up of two parallel lines differing in length and joined at the tops by a cross bar is presented (similar to the Greek letter Pi ).
