Whether a further increase in ecological validity of the task would be useful, should be tested empirically in future research.
Results showed a significant increase in criterion validity from generic, to tagged, to completely contextualized personality scales.
This procedure represents a modest increase in external validity by having items in a physical configuration in which people can see them from different angles, move closer and further away, examine details present in real objects, and allocate their attention according to their motivation.
An increase in the validity of a manuscript selection process hence increases the probability that qualified submissions (later highly-cited publications) are selected and unqualified submissions (later publications with low citation counts) rejected, other things being equal [see here 15].
The increase in ecological validity and the potential for revealing interactions between different levels of hierarchical processing suggest that such paradigm is well suited for elucidating the mechanisms of perceptual learning in the human brain.
While there are differences revealed between institutions, across years and among the tools used for admissions, one constant shown through this study is that the use of multiple tools does result in an increase in predictive validity.
Taken overall, Figure 1 shows that PACES performance is a good predictor of CSA performance, and that the new CSA is being predicted better than was the old CSA, implying an increase in the validity of the new CSA over the old.
In terms of any evidence of incremental validity (the increase in predictive power by the addition of another selection tool) [ 1], the data in Table 4 suggest that there may be a possible gain in validity resulting from the addition of the HPAT to the existing selection process.
The advantage that comes along with this design however, is an increase in the ecological validity of both trials.
The sample weighting used in this study allowed an increase in the external validity and a better estimate of the prevalence of L. intracellularis infection in Minas Gerais and allowed comparisons to different sampled regions and pig categories.
