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.
The experimental approach to mental chronometry includes topics such as the empirical study of vocal and manual latencies, visual and auditory attention, temporal judgment and integration, language and reading, movement time and motor response, perceptual and decision time, memory, and subjective time perception.

There are three levels of processing in this model. Structural processing, or visual, is when we remember only the physical quality of the word (e.g. how the word is spelled and how letters look). Phonemic processing includes remembering the word by the way it sounds (e.g. the word tall rhymes with fall).
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.
At time zero, the evidence accumulated, x, is set equal to zero. At each time step, some evidence, A, is accumulated for one of the two possibilities in the 2AFC. A is positive if the correct response is represented by the upper threshold, and negative if the lower. In addition, a noise term, cdW, is added to represent noise in input.
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.
An example of visual capture is the ventriloquism effect, that occurs when an individual's visual system locates the source of an auditory stimulus at a different position than where the auditory system locates it. When this occurs, the visual cues will override the auditory ones.
The most significant period for the development of auditory-visual integration occurs between ages 5–7. During this time, the child has mastered visual-kinesthetic integration, and the child's visual learning can be applied to formal learning focused towards books and reading, rather than physical objects, thus impacting their intellect.
