Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
The latency to pain-reflex behavior is measured. [1] One complication of this assay is its unsuitability for repeated testing. Animals that have been subjected to the hot-plate test in the past display a behavioral tolerance phenomenon, which is characterized by decreased latencies and reduced sensitivities to antinociceptive agents.

Latency, path length to escape box, and number of errors to the first nose poke at the escape hole have been used as measures previously. [11] Another drawback to the Barnes maze is that when testing multiple animals, scent cues left on the maze by the previous animal could alter the performance of subsequent subjects.
The test was developed to study spatial learning and how it differed from other forms of associative learning. [11] Originally rats, now more commonly mice, were placed in an open pool and the latency to escape was measured for up to six trials a day for 2–14 days. [12] Several variables are used to evaluate an animal's performance.
In psychometrics, item response theory (IRT, also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.
Test data are sets of inputs or information used to verify the correctness, performance, and reliability of software systems. Test data encompass various types, such as positive and negative scenarios, edge cases, and realistic user scenarios, and aims to exercise different aspects of the software to uncover bugs and validate its behavior.
The samples of behavior must be reasonably representative of the behavior in question. The samples of behavior that make up a paper-and-pencil test, the most common type of psychological test, are written into the test items. Total performance on the items produces a test score.
The NIH Toolbox, for the assessment of neurological and behavioral function, is a multidimensional set of brief royalty-free measures that researchers and clinicians can use to assess cognitive, sensory, motor and emotional function in people ages 3–85.
