In an experiment (Schienle et al. 1996) 22 believers and 20 skeptics were asked to judge the covariation between transmitted symbols and the corresponding feedback given by a receiver.
The extracted variables are known as latent variables or factors; each one may be supposed to account for covariation in a group of observed variables.
