Brief Reasoning Measure Validation

Measure

SgS-12 A/B is the short reasoning snapshot used by IQMindware Tracker for pre/post programme checks.

The measure is designed to provide a practical fluid-reasoning signal: pattern discovery, rule inference, mental transformation, and unfamiliar problem solving. It is used as a tracking measure for training studies and personal baselines, not as a high-stakes or diagnostic IQ assessment.

Current forms

  • Form A is used as the pre-training baseline.
  • Form B is used as the post-training follow-up.
  • Each form contains 12 items.
  • Item families include matrix reasoning, verbal reasoning, letter/number series, and three-dimensional rotation.
  • There is no strict speed-pressure scoring in the current implementation; the intended signal is careful reasoning accuracy under consistent testing conditions.

Source item families

The current SgS-12 A/B forms are documented in the Tracker validation notes as being built from public-domain International Cognitive Ability Resource (ICAR) item families:

  • ICAR Matrix Reasoning
  • ICAR Verbal Reasoning
  • ICAR Letter and Number Series
  • ICAR Three-Dimensional Rotation / R3D

These item families are part of the ICAR project, which was created to support flexible, well-validated cognitive ability assessment resources for research use. ICAR's public item-type listing includes Three-Dimensional Rotation, Letter and Number Series, Matrix Reasoning, Verbal Reasoning, Progressive Matrices, Number Series, and Perceptual Maze.

The older G-Tracker documentation also references the Open Matrices Item Bank (OMIB) as an open, validated source for matrix-reasoning items. OMIB is a separate figural-matrices item bank, developed from 220 construction-based matrix items and evaluated in a large field sample. Where OMIB assets are used or referenced, their own source and licence terms should be followed. The current SgS-12 A/B forms are broader than OMIB alone because they include verbal, series, and rotation item families as well as matrix items.

Validation foundation

The validation foundation is item-family based rather than a claim that SgS-12 A/B is a full standalone professional IQ battery.

Relevant foundations:

  • ICAR was developed and initially validated as a public-domain cognitive ability resource. Its early validation work reported structural, concurrent, and discriminative validity evidence for the first item types.
  • The current SgS-12 forms use ICAR-style item families with published psychometric foundations and known item-type behaviour.
  • OMIB provides a published validation foundation for open matrix-reasoning items where OMIB-style or OMIB-sourced matrix assets are used in Tracker contexts.

Because SgS-12 uses only 12 items per form, it should be interpreted as a brief reasoning snapshot. It is appropriate for baseline/follow-up tracking inside the programme, but it should not be presented as a definitive IQ test, clinical assessment, or high-stakes selection tool.

Intended use

  • Pre-training and post-training reasoning snapshots.
  • Aggregated programme evaluation.
  • Self-tracking under consistent conditions.
  • Research and product validation where claims are bounded and caveated.

Not intended for

  • Diagnosis.
  • Treatment decisions.
  • High-stakes selection or certification.
  • Standalone claims of a fixed IQ score.
  • Claims that any individual score change proves far transfer.

Interpretation caveats

  • Short forms are noisier than full-length professionally administered batteries.
  • Practice effects can occur in repeated testing, even with alternate forms.
  • Sleep, stress, distractions, device differences, and motivation can affect performance.
  • Improvements should be interpreted alongside programme completion data, Tracker history, and delayed re-checks.
