The difference between the invalid and the valid trials (without the non-cued condition) was not modulated by the group factor [ F < 1].
In attempts to solve such logical puzzles, a logical terminology develops here, too, and the focus on the difference between valid and invalid arguments sets the scene for the search for a criterion of valid inference.
For our limited purposes here, were use it merely to mark the difference between a valid argument, recorded as a 'rule form', and the provability of a conditional, reported as a 'conditional form'.
Although the signal intensity follows the theoretical distribution pattern over a certain range for both chips, there is a marked difference in the valid intensity range between the two chips.
Cuing effects are reported as the difference in reaction time between the valid and invalid trials aggregated for each subject.
Moreover, the RT difference between invalid and valid trials increases, the higher the proportion of validly cued trials (percentage of cue validity [%CV]; Jonides 1980; Eriksen and Yeh 1985; Giessing et al. 2006; Risko and Stolz 2010).
A further paired t-test on the magnitude of IOR (i.e., the RT difference between valid and invalid trials) for the two stimulus eccentricities revealed a stronger IOR magnitude for 21° versus 7° stimuli (34 ms vs. 22 ms, t(15) = −5.783, p <.001), showing an eccentricity effect of IOR.
The purpose of logic is to characterize the difference between valid and invalid arguments.
To determine where the largest errors between satellite field models and models derived from ground-based measurements arise, we examined the difference between IGRF-7 model (valid 1995 2000) coefficients as defined for 1995 and the DGRF model for 1995 from Chambodut et al. (2005).
There was no statistically valid difference between the time dependent generation of C5a fragment in the serum contacting the particle-free cryogels and the composites (Figure 5a,b).
