HCD.12:4.2 - Design a discriminating unfamiliar task

Choose a task the person has not rehearsed in its decision-bearing form. State the changed fact, the response it should change, the criterion and the allowed means. Ask how a copied answer, an indiscriminate refusal and a lucky guess would fare.

Where the work requires both action and restraint, include sufficient-evidence and insufficient-evidence cases. A useful small comparison may be one condition that supports action and another that changes its limit. Broader transfer claims need coverage of the material variation they include; a single convenient task cannot supply it.

Keep irrelevant difficulty controlled where possible. If both the tool and the work problem change, either explain why that combined condition is the intended question or separate the changes enough to interpret failure.

Before use, have the domain criteria and expected consequences available. A task whose own correct answer is disputed cannot settle the person’s transfer.
