This protocol describes the 5-choice serial reaction time task, which is an operant based task used to study attention and impulse control in rodents. Test day challenges, which are modifications of the standard task, increase flexibility of the task and can be combined with other manipulations to more fully characterize behavior.

Objective and easy measurement of sensory processing is extremely difficult in nonverbal or vulnerable pediatric patients. We developed a new methodology to quantitatively assess infants and children's cortical processing of light touch, speech sounds, and the multisensory processing of the 2 stimuli, without requiring active subject participation or causing discomfort in vulnerable patients.

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA The goal of this experiment is to determine the magnitude of maldistribution in typical packed bed reactors in both single phase and two-phase (gas-liquid) flow and evaluate the effects of this maldistribution on pressure drop. The concepts of residence time distribution and dispersion are introduced through the use of tracers, and these concepts are related to physical...

Presentation pace changes the time available to retain the preceding digit, perform the addition, and report the result before another stimulus arrives. A faster pace increases the demand on working memory, processing speed, and sustained attention, while comparing performance across paced conditions helps researchers examine how cognitive pressure affects sequential auditory information processing.
Successful performance requires several linked operations: the participant must attend to each auditory digit, retain the immediately preceding value, update that information when the next digit arrives, calculate the sum, and respond promptly. Because these operations occur repeatedly in sequence, PASAT performance provides information about working memory, sustained attention, processing speed, and executive control.
The task imposes pressure by requiring accurate mental operations and spoken responses within fixed time intervals. As the pace changes, participants must coordinate attention, temporary information retention, calculation, and response timing without pausing the sequence. This makes performance useful for examining how stress or fatigue may influence cognitive control and auditory processing.
The principal adjustable condition described for the PASAT is the interval between successive single-digit auditory stimuli. Holding the task structure constant while changing this pace allows researchers to compare performance under different levels of time demand. The resulting comparison can reveal changes in processing speed, working-memory performance, sustained attention, and response under cognitive pressure.
Researchers can use performance on the PASAT to quantify changes in auditory information processing and executive control. Comparisons across task conditions or participant states may show altered working memory, attention, processing speed, or tolerance of cognitive pressure. These outcomes support behavioral analysis rather than relying only on subjective descriptions of concentration or fatigue.
The PASAT is relevant when researchers need a standardized behavioral measure of sequential auditory cognition. The overview identifies applications in studies of cognition, neurological function, fatigue, and stress. In these settings, task performance can help characterize changes in information processing and executive control while participants manage repeated mental operations under timed conditions.
