The instrument is used to measure 21 a person's body reacts to questions. The theory underlying it is that lying is stressful, and that this stress can be measured and recorded on a polygraph machine. When a person takes a polygraph test, four to six wires, called sensors, are 22. to different parts of his body. The sensors pick up signals from the person's blood pressure, pulse, and perspiration. 23 the process of questioning, all the signals are recorded on a single strip of moving paper. Once the questions are finished, the examiner analyzes the results to determine if the person tested 24. truthful. Well-trained examiners can usually detect lying with a high degree of 25. when they use a polygraph.

A recent study favorably evaluates the con struct validity of the DIAL-3 through confirmatory factor analysis (Assel & Anthony, 2009). As noted the instrument was designed to screen for devel opmental delays in three domains: motor abilities, conceptual knowledge, and language competence. An essential feature of the test is that separate scores are reported for each domain. These domains and the 74 fubtests comprising them were rationally precon- derved by the test authors. An important question is whether the 21 subtests “hang together” statistically in a manner that supports the rational grouping into the three domains provided by the test developers, In other words, do the three domains possess a latent reality, or are they merely figments of the imagina- tions of the test developers? Using test results for 1,560 children ages 3 to 6, Assel and Anthony (2009) found an excellent fit between the three domains tra- ditionally reported on the DIAL-3 and three empiri- cally derived domains found through factor analysis, which supports the construct validity of the test.
