That is, within CTT a person's test score may easily vary depending on which test is being administered and, in turn, the difficulty of the same item depends on which sample is being assessed.
An outcome of the new approach is a reduction of equations of a dynamic system of any complexity to a set of the matrix final equations, linear and bilinear equations, for which the solution's difficulties are fundamentally less than the solution's difficulties of the same problems in conventional representations.
The use of multiple levels of difficulty within the same basic task paradigm also allows us to probe how localization and lateralization of function might change with task demands.
It is, of course, a sympathetic voice, especially when joshing the passive aggression of wig-wearers ("you lot are going to have to collude in the illusion that I've still got a barnet") or, in a lovely closing routine, negotiating the social difficulty of encountering the same vague acquaintance three times on one shopping trip.

As participants were not asked to re-estimate the level of difficulty with the same activity at post mSTEPS, and thus a change in activity-specific disability could not be calculated, we chose to tabulate the frequencies of reported difficulties with commonly listed activities, and to use the data for a baseline sample description only.
Since step-sizes were a constant fraction of the standard duration, difficulty of discrimination was the same for the three standard durations given that the eleven probes were approximately the same proportion of the standard.
