A real-time polymerase chain reaction ( real-time PCR, or qPCR when used quantitatively) is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR (i.e., in real time), not at its end, as in conventional PCR.
The Posner cueing task, also known as the Posner paradigm, is a neuropsychological test often used to assess attention. Formulated by Michael Posner, [ 1] it assesses a person's ability to perform an attentional shift. It has been used and modified to assess disorders, focal brain injury, and the effects of both on spatial attention.
About 0.17% to 0.89% (pre- COVID-19 pandemic) [ 9] Myalgic encephalomyelitis/chronic fatigue syndrome ( ME/CFS) is a disabling chronic illness. People with ME/CFS experience profound fatigue that does not go away with rest, sleep issues and problems with memory or concentration. Further common symptoms include dizziness, nausea and pain.

Stroop effect. Naming the displayed color of a printed word is an easier and quicker task if the word matches the color (top) than if it does not (bottom). In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the Stroop test) that is ...
In psychology, impulsivity (or impulsiveness) is a tendency to act on a whim, displaying behavior characterized by little or no forethought, reflection, or consideration of the consequences. [ 1] Impulsive actions are typically "poorly conceived, prematurely expressed, unduly risky, or inappropriate to the situation that often result in ...
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 ...
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.
RT-PCR. Reverse transcription polymerase chain reaction ( RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). [ 1] It is primarily used to measure the amount of a specific RNA.
