05), but when the AH4 part 1 score was entered first, spatial ability test score did contribute significant further predictive power ([[Chi].
In an exploratory analysis, to discover how much cognitive test ability variance could be accounted for when the visual processing tests were combined, two stepwise regression analyses were carried out, using AH4 I and II scores as the dependent variables.
Transformed data from the three cognitive ability tests (NART, AH4 I and AH4 II) and the three visual processing tests (IT, VCD and VMD) were subjected to a confirmatory latent trait analysis using structural equation modelling.

at WJ's ISO9000 certified GaAs and thin film facility, the AH4 high dynamic range amplifier is packaged in state-of-the-art Ball Grid Array (BGA) package.
The AH4 extends the linear efficiency advantages (OIP3) of WJ's successful AH1 to higher frequencies.
