Thus the ones who had points between 0-12 were coded and categorized as participants who use analytical thinking (preferences of non-visual methods) and the ones who had points between 22-36 were coded and categorized as participants who use visual thinking (preferences of visual methods).
Interestingly, there was a significant correlation between the visual observation method and the hygroscopic measurements [ 49].
This should be done with a clear awareness of the differences between the visual examination method and the photographic assessment method.
With respect to the statistical analyses of survival curves, the Kaplan-Meier method, where differences in outcome between groups is tested with the log-rank test, provides a useful (and visual) method for assessing differences in survival curves.
Both visual methods (Visual1 and Visual2) yielded equivalent mean error of approximately four degrees; Unlike MultiWind method and all others, the MonoWind approach seemed less efficient for finding close limits between the right and left sensors.
The observed variability between visual and automated methods mostly occurred between adjacent groups, only 2 patients with negative visual score were in the automatically assessed high extent group, and none of the patients with high visual score were classified by the automated analysis into the low extent group.
For each trial, subject, limit, and method, an error between visual estimates and all others methods has been computed and average results compared to subjects and trials are presented in Figure 11.
Despite the development of new rating scales and visual methods, then, the boundaries between what Martin Roth called 'senile dementia and its borderlands' remain blurred, and psychiatrists acknowledge that 'clinical judgements' remain vital in these instances (ibid.: 27; Roth, 1980).
The study used a set of methods, which included written methods such as listings and essays, visual methods such as visual stimuli and drawings.
The choice of method can thus be a choice between simplicity, with the visual methods easy to use approach, or thoroughness, with the rheological measurements supported by the Winters Chambon theory.
