SOM.2:4 - Solution

SOM.2:4.1 - Construct an accessible contrast

Select two already available, comfortable variants of one task-relevant change. Vary the support, intended direction or amount only as needed to make the contrast accessible. Keep other conditions alike where possible; note any changes that could explain the difference.

Compare the first variant, the second and a return to the first. Attend to what changes during the action and after release. The return helps distinguish the proposed contrast from an unfamiliar one-time event.

In familiar writing, compare the usual pen hold with a slightly lighter hold while the forearm rests in its usual supported position. Return to the usual hold. Do not deliberately increase load to obtain a stronger sensation.

SOM.2:4.2 - Locate what is distinguishable

Ask where the change is experienced, in which direction and how it develops. The answer can initially be a broad region, a gesture or “no reliable difference.” Bodily landmarks help recover a location without asserting which tissue produced the experience.

Use a coarser contrast or different suitable support when the distinction is unavailable. Do not require the performer to report the teacher’s expected sensation. Refine the region only when the next action needs that resolution.

An effort that is outside attention and an effort that is involuntary are different matters. Exploring a previously unnoticed change may make it reportable without making it controllable.

SOM.2:4.3 - Connect the contrast to action

Use the contrasted variants in a small instance of the receiving movement. Compare the experienced change with the relevant external result. In writing, make a familiar mark and observe pen security, guidance and contact. Retain coupling between those actions if changing the hold affects them together.

If the lighter hold cannot keep the pen secure, return to an available hold. That boundary is informative; the lightest effort is not the goal. A distinction can remain useful even when one variant is unsuitable for performance.

Proceed to SOM.3 only for a change the performer can identify but cannot yet regulate as required. If the distinction disappears in the full action, preserve the conditions under which it was available and construct the needed combination or support transition. Do not report transfer from the preparatory contrast alone.
