WebFigure 1: Reflectivity Test Setup. Data Correction Before measuring reflectance of the samples, a scan was run with Spectralon® to provide a reflectivity standard. All subsequent samples were then measured relative to this established standard. Since the absolute reflectivity of the Spectralon® standard is known, the sample data was corrected to According to Frederick, there are two general types of cognitive activity called "system 1" and "system 2" (these terms have been first used by Daniel Kahneman). System 1 is executed quickly without reflection, while system 2 requires conscious thought and effort. The cognitive reflection test has three … See more The cognitive reflection test (CRT) is a task designed to measure a person's tendency to override an incorrect "gut" response and engage in further reflection to find a correct answer; however, the validity of the … See more Studies have estimated that between 44 and 51% of research participants have previously been exposed to the CRT.
