This further research should involve assessment of perceived difficulty, as well as objective measurement of the difficulty of the scenarios used, perhaps using panels of GPs.
While no studies assessed the relationship between perceived difficulty and appropriateness, one study objectively varied the difficulty of the scenarios and assessed the relationship between a measure of objective difficulty and appropriateness.
The game modes dictate the difficulty of the scenario, as well as whether people can choose their hero or are assigned one randomly.
The ease or difficulty of the scenario exerted a statistically significant effect (F (1, 289) =247.76, P < 0.001) on the proportion of correct judgments.
Nevertheless, this trend may be the result of the increased difficulty level of Scenario 2 as compared to Scenario 1 or other factors that have not been fully evaluated.
For chromosome Z, the variability was large and increased with the increasing difficulty of the imputation scenario.
Only one study provided difficulty scores per scenario [ 19]: in the other studies, perceived difficulty was assessed for the set of scenarios as a whole [ 20], or difficulty scores were summed across scenarios [ 16, 17] (see Table 4).
Until not too long ago, the difficulty to model this type of scenarios with essential nesting was an important limitation to feasibly study AR evolution processes.
Given the difficulty of moving beyond predictable scenarios within the allotted four minutes, few of these plays manage to be formally inventive.
The study highlights the difficulty of developing ad hoc scenarios for SMEs due to the sheer imbalance between assets and the fact that their major partners are both looking for low-risk, fast-payback models.
