NNAT3 Level D flashcards
NNAT3 Level D · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Matrix cell rule
- In a grid puzzle, the missing cell must satisfy the row rule and the column rule at the same time. Test each candidate against both directions.
- Color inversion rule
- A transformation swapping black and white fills. If the first two cells of a row invert, the third cell inverts again, restoring the original color.
- Rotation in a matrix
- A shape turned by a fixed angle from cell to cell. In a 3x3 grid, the third column usually continues the same rotation step seen in the first two.
- Mirror flip across axis
- A reflection producing a reversed, non-rotatable copy. A flipped L-shape has opposite handedness from the original and cannot be reached by rotation alone.
- Attribute checklist method
- Compare each option on outer shape, inner shape, fill, orientation, element count, and position. Distractors usually match all but one attribute.
- Diagonal confirmation
- In 3x3 matrices, a consistent transformation along a diagonal supports an answer but does not replace the required row and column checks.
- Tie-break with column rule
- When two options both satisfy the row rule, apply the column rule. Exactly one option should survive both constraints.
- Frame versus fill
- The border of a figure and its interior are separate attributes. A correct option must match both; distractors often match only the border.
- Analogy format A:B::C:?
- The relation linking the first pair must be applied unchanged to the third figure. The answer is whatever the relation produces from C.
- Verbalize the relation
- Describe the first pair in words, such as rotate 90 degrees clockwise, before examining options. This blocks visually appealing but logically wrong choices.
- Direction of relation
- The relation runs from first figure to second. If A grows into B, then C shrinking implies the answer grows, not shrinks.
- Inverse-relation distractor
- An option built by applying the reverse transformation. It looks related to the pair but reverses the required direction.
- Partial transformation
- An option where only one attribute changed, such as color but not orientation. Reject it when the model pair changes both.
- Whole versus component
- In figures with two shapes, decide whether the relation applies to the entire figure or to one part. Mixed figures often transform only the inner shape.
- Identity distractor
- An option that simply repeats C unchanged. It is correct only when the model pair shows no change between its two figures.
- Uniqueness test
- A correctly stated analogy relation yields exactly one valid answer. Two fitting options mean the relation was described too loosely.
- Shape substitution relation
- A rule where one shape type replaces another, such as triangle to square. Apply the same substitution to the third figure's shape.
- Constant step rule
- In a series, each figure differs from the previous by a fixed change in count, angle, or position. Extrapolate that step to the blank.
- Rotation series modulo 360
- If a figure rotates 90 degrees per step, the total after n steps is 90n degrees. Reduce modulo 360 to find the actual orientation.
- Alternating series
- Two interleaved sequences share one row: odd positions follow one rule and even positions another. Identify which subsequence contains the blank.
- Progressive series
- The step size itself changes, as in adding 1, then 2, then 3 elements. The second difference confirms an arithmetic progression.
- Shading cycle period
- A fill pattern that repeats every 2 or 3 figures. The blank's fill is fixed by its position modulo the period.
- Corner position cycle
- An element moving clockwise around four corners returns to start after four steps. Treat its location as a counter modulo 4.
- Full-pair verification
- Check the proposed series rule against every consecutive pair, not only the pair next to the blank. One violated pair invalidates the rule.
- Count-based series
- A series where sides, dots, or elements increase or decrease by a constant amount. Count each figure and solve for the missing term.
- Mental rotation preserves chirality
- Rotating a figure never turns it into its mirror image. An option with reversed handedness is wrong no matter how it is oriented.
- Chirality check
- Compare handedness of the target and the option. A rotated L-shape stays an L; a mirrored L is a different figure entirely.
- Unfold in reverse order
- For paper-folding punches, undo each fold from last to first, reflecting every hole across the fold line at each step.
- Hole doubling on unfold
- Each unfold doubles the hole count unless a hole lies exactly on the fold line, in which case it maps onto itself and does not double.
- Cube net opposite faces
- Faces separated by exactly one face along a straight line of the net are opposite each other. Opposite faces never share an edge.
- Transparent versus opaque overlay
- In transparent figures, overlapping regions show combined fill. In opaque figures, the top layer hides whatever lies beneath it.
- Counting stacked blocks
- The height of a column equals the number of visible top faces in that column. Total blocks equal the sum of all column heights.
