SYSE.46:5.2 - A person’s arithmetic and order information

A person reports the total for six lots. Keep ordinary arithmetic means available while varying optional access to the relevant order document. One card already supplies 347 per lot; another matched task omits the current lot size; a third supplies the needed facts but offers an unrelated order. Supplied-support trials identify which order lookup to perform; the person must still recover the right quantity, calculate and report. In the missing-fact case, no-support work should return the gap, while a useful lookup can supply the fact needed to obtain 2082. In the sufficient case, extra lookup needs a benefit that repays its burden.

Use different matched orders and values, with order/allocation chosen for the claim, so the first exposure does not give away a later answer. Record errors, unnecessary or missed lookup, result use and relevant burden separately. If the person learns during the comparison or becomes fatigued, bound the attribution accordingly. Correct supported arithmetic does not establish later unaided learning; that separate question uses HCD’s tests.
