Construct Validity
We examined further the structure of the of the action map by performing a factor analysis
with Quartimax rotation on the variables derived from the action map. The analysis
provided support to the two- factor structure (Table 5): Factor 1 with high
loadings on the type of action (relative frequency of mnemonic actions, relative frequency of
cognitive actions, relative frequency of perceptual actions) and Factor 2 with high loadings
on the structure of the action map which reflect the complexity of the activity(number of
actions and number of loops)
