Through sorting the memorandums into different groupings, and constantly comparing how each memorandum related to another [ 13], relationships emerged between the different concepts, giving the categories dimension and position within a theoretical framework [ 19, 20].
Through the sorting and resorting of the memos into different groupings and constantly comparing how each memo was related to another [ 22] the researchers developed a better understanding of the relationships between different concepts and categories, giving the categories dimension and position within the evolving understanding of the situation [ 28].
As they put it: EmotionML provides mechanisms to represent emotions in terms of scientifically valid descriptors: categories, dimensions, appraisals, and action tendencies.
Whether, in the long run, this is best achieved by using categories, dimensions or some mixture of the two will require future study.
To ensure that we addressed all major categories (dimensions) of general quality of life, two investigators (JS and SW) developed a brief set of questions, based loosely on Flanagan's Quality of Life Scale, which were used in the focus groups and interviews [ 20].
In an experimental setting, the von Restorff effect is often studied by presenting participants with a list of words sequentially, with one word being more distinct in a perceptual (e.g., font color, font size) or conceptual (e.g., emotional, semantic category) dimension.
Their scheme has only three to four categories per dimension, where each dimension is evaluated separately from the rest.
The value of discrimination measure for the GC% categories on dimension 1 was greater than that on dimension 2 (Additional file 8).
However, the EQ-5D has been criticized for having only three response categories per dimension, which could lead to lack of measurement precision and responsiveness (see e.g. Pickard et al).
Three broad categories or dimensions emerged and were named by the research staff after reviewing each the underlying factors of each dimension (see Figure 2): (1) organization hosting the network, (2) threat/adversary, and (3) contractors (prime contractor, sub-contractors).
Both categorical and dimensional methods appear relevant to classifying psychotic disorders; however, there is no clear consensus on the most appropriate categories and dimensions or on the best approach for constructing nosologic criteria that integrate these 2 methods.
