Over half of those encountering difficulty, resulting in disrupted progress or departure from the programme, could be identified by a count of two or more flags – markers of difficulty - in the first 18 months.
Although, therefore, it is possible that some characteristics of these struggling students are also present amongst those who do not, it seems unlikely that the markers of difficulty reported here – flags - would occur as more than the occasional one or two flags.
Interestingly, this occurred despite no difference in any measurable marker of technical difficulty.
Second, although emergency presentations are multifactorial, they do seem to represent a marker of 'diagnostic difficulty' after presentation.
Early weaning may be a marker of feeding difficulties in heart failure.
To counteract this bias, more challenging cases were preferentially selected for the test set, using striatal binding ratio results as a surrogate marker of the likely difficulty in classifying the data.
The task also reveals deficits in people who appear to have overcome early developmental language difficulties, and so it acts as a good marker of resolved language difficulties.
We also know that, for ASD in particular, while differentiation of siblings who experience later problems within the first year of life is difficult, there is a constellation of phenotypes that emerge after 12 months that may be key markers of later difficulties.
Results show that a 10-year age marker is a better discriminator of difficulty levels than a 5-year age range.
In a dual-task condition, an increased RT can thus be considered as a marker of an increased postural task difficulty [14], [15], [19].
