Continuous performance task. A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli, and is associated with impulsivity.
Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...
The tail suspension test ( TST) is an experimental method used in scientific research to measure stress in rodents. It is based on the observation that if a mouse is subjected to short term inescapable stress then the mouse will become immobile. It is used to measure the effectiveness of antidepressant -like agents but there is significant ...
Prepulse inhibition: preceding stimulus attenuates the startle response. Prepulse inhibition ( PPI) is a neurological phenomenon in which a weaker prestimulus ( prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus ( pulse ), often using the startle reflex. The stimuli are usually acoustic, but tactile ...
Tetrad test. The tetrad test is a series of behavioral paradigms in which rodents treated with cannabinoids such as THC show effects. [1] [2] It is widely used for screening drugs that induce cannabinoid receptor -mediated effects in rodents. The four behavioral components of the tetrad are spontaneous activity, catalepsy, hypothermia, and ...
Doctors have termed this the “HAMA response,” referring to the development of Human Anti-Mouse Antibodies (HAMA). The HAMA response is essentially an allergic reaction to the mouse antibodies that can range from a mild form, like a rash, to a more extreme and life-threatening response, such as kidney failure.
Two-alternative forced choice. Two-alternative forced choice ( 2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the ...
Tail flick test apparatus. The tail flick test is a test of the pain response in animals, similar to the hot plate test. It is used in basic pain research and to measure the effectiveness of analgesics, by observing the reaction to heat. It was first described by D'Amour and Smith in 1941. [ 1]
