Does the model of hierarchical complexity produce significant gaps between orders and are the orders equally spaced?

The model of hierarchical complexity (MHC) provides an analytic a priori measurement of the difficulty of tasks. As part of the theory of measurement in mathematical psychology, the model of hierarchical complexity (Commons and Pekker, 2008) defines a new kind of scale. It is important to note that the orders of hierarchical complexity of tasks are postulated to form an ordinal scale.

Do forensic practitioners distinguish between testifying and consulting experts? A pilot study.

Forensic mental health professionals (n=44) reviewed a series of statements that an attorney might make to a consulting or testifying expert. Each statement was rated for its degree of appropriateness to either the consulting or the testifying role. In light of increasing attention paid to this topic in the forensic practice literature, as well as long-standing distinctions recognized by the legal profession, it was originally hypothesized that participants would differentiate clearly between these roles; however, results of this pilot study indicate that forensic practitioners do not possess a consistent sense of which activities rest most comfortably within testimonial as opposed to consulting duties.
