Abstract
The metric devised by Halford, Wilson & Phillips may have
considerable potential in distinguishing between the working memory
demands of different tasks but may be less effective in distinguishing
working memory capacity between individuals. Despite the strengths
of the metric, determining whether an effect is caused by relational
complexity or by differential levels of expertise is currently
problematic.
