Griffith, Wahl and Izurieta (2011) introduced the TrueRefactor tool to find and remove a set of code smells from a program in order to increase comprehensibility.
For example, the Danish translation of item 3 deleted "I am satisfied that" to increase comprehensibility of the item in Danish.
The members of warning concept triplets differed not only in terms of comprehensibility and complexity but also in terms of how increased comprehensibility and complexity were implemented – that is, in terms of the types of contextual cues that were added to increase comprehensibility and complexity.
Alternatively, it may be the case that the increased visual complexity would inhibit comprehension of the symbols – that is, the increased complexity may prevent, or override, a benefit of increased comprehensibility.
In addition, the predictions regarding the effects of symbol characteristics on reaction times are unclear because increased complexity might be expected to lengthen initial visual processing, whereas increased comprehensibility might be expected to shorten the decision stage.
This pretest prompted changes that essentially involved spelling out both the main question and answer options more thoroughly (e.g. "problems with running" instead of "running" and "never was a problem" instead of "never") to increase comprehensibility.
In conclusion, our results indicate that symbols should be designed to be comprehensible as possible (i.e. to have a high probability of having its meaning guessed) and that, in some instances, added complexity can increase comprehensibility.
In order to increase comprehensibility in the reporting phase, we hereby distinguished between slight frailty (ZZP 1), moderate frailty (ZZP 2 and 3), and severe frailty (ZZP 4, 5, and 6).
To produce these triplets, it was sometimes necessary to (1) increase an existing symbol's complexity, while also increasing its comprehensibility, (2) decrease a symbol's comprehensibility, while maintaining its complexity and (3) increase a symbol's complexity, while decreasing its comprehensibility.
However, for younger viewers this reduced complexity may accentuate critical expressive features and increase comprehensibility, which in turn leads to increased attention (Pempek, Kirkorian, Richards, Anderson, Lund & Stevens, 2010, Kidd, Piantadosi & Aslin, 2012).
