Pattern Completion task format

A large design has a blank region and four candidate patches are offered. Exactly one patch continues every line, color, and shape across the boundary of the missing area.

Edge continuity rule

Any line or color region touching the hole must continue into the patch at the same angle, width, and color. A patch that shifts or flips these elements is wrong.

Symmetry shortcut for patches

If the design is symmetric about a vertical, horizontal, or diagonal axis, reflect the visible portion across that axis to predict the missing region before comparing answer options.

Common pattern-completion distractors

Wrong patches usually mirror the correct patch, shift it by one repeating unit, swap two colors, or drop a single line. Check each option for these specific defects.

Repeating-unit spacing check

When a design repeats stripes, dots, or nested shapes, measure the spacing and size of units next to the hole. The correct patch preserves that spacing exactly.

Crossing-point rule

Where two pattern elements intersect inside the missing region, the correct patch places the crossing point exactly where the visible continuations of both elements would meet.

Rotation in pattern completion

Patches are normally in the same orientation as the surrounding design. An option that is rotated relative to the design is almost always a distractor.

Analogy item structure

The item states A is to B as C is to a blank, with four answer options. The transformation linking A and B must be applied to C in the same direction.

Name the relation first

Before examining options, describe the A-to-B change in words, such as add one side, rotate 90 degrees, invert colors, or move the dot to the opposite corner.

Inverse-relation distractor

An option that applies the reverse of the A-to-B change, such as removing a side when A gained one, is incorrect even though it looks plausible.

Attributes compared in analogies

Compare shape identity, number of elements, size, orientation, fill color, outline versus solid, and position in the frame. The A-to-B relation changes only some of these.

Compound relation rule

When A and B differ in two ways, such as rotation plus color change, the correct answer must show both changes applied to C. Options showing only one change are wrong.

Negative relation in analogies

If A loses an element to become B, then C must lose the same element. An option that adds an element instead reverses the relation and is incorrect.

Analogy verification step

After choosing an answer, reread the item as A is to B as C is to the chosen option. Both pairs must obey the identical stated relation.

Serial Reasoning matrix format

A 2x2 or 3x3 grid has one empty cell. A rule progresses across rows and down columns, and the missing cell must satisfy both readings at once.

Progression types to test

Test in order: constant addition or subtraction of elements, fixed-step rotation, size growth or shrinkage, color alternation, and position shift by one cell.

Arithmetic counting progression

If rows show element counts increasing by a constant step, the missing cell continues that sequence. Repeating an earlier value instead of continuing the sequence is a distractor.

Diagonal symmetry in matrices

Many matrices are symmetric about a diagonal. The missing cell can then be predicted by reflecting the cell opposite it across that diagonal.

Row-column double constraint

The missing cell must complete the row pattern and the column pattern simultaneously. An option that fits the row but breaks the column is incorrect.

Duplicate-cell exclusion

If no row or column elsewhere contains identical cells, eliminate any option that would create a duplicate within the missing cell's row or column.

Rotation direction consistency

When shapes rotate clockwise across a row, they normally rotate clockwise down the column as well, unless the item establishes separate row and column rules.

Serial reasoning distractor types

Wrong options repeat a cell already present, satisfy the row rule but violate the column rule, or continue the sequence with the wrong step size.

Spatial Visualization operations

These items require mental folding, rotation, reflection, or combination of shapes. The answer is the option matching the result of the stated operation.

Folding mirror rule

When a shape folds along a line, the crease stays fixed and the moving half lands as a mirror image across that line. Features reverse position relative to the fold.

Rotation versus reflection test

Track one landmark feature. A 90-degree rotation moves a top-left dot to top-right, while a reflection produces a different placement unless the figure is also flipped.

Landmark feature tracking

Choose one distinctive feature such as a dot, notch, or asymmetric protrusion. Follow only that feature through the operation, then check which options place it correctly.

Paper-folding punch unfolding

Unfold in reverse order, reflecting each hole across the fold line in turn. Holes double with each unfold unless a hole lies on the crease and coincides with its reflection.

Shape combination edge rule

When two pieces join, matching edges must be equal in length and the pieces must not overlap. Options showing overlap or mismatched edge lengths are incorrect.

Cube net opposite faces

Opposite faces of a cube never appear adjacent. Eliminate any option showing two faces that are opposite each other in the given net.

Chirality check

The most common distractor is the correct figure reflected rather than rotated. Confirm that a clockwise sequence of features stays clockwise in the chosen option.

Mental rotation strategy

Rotate the whole figure in fixed steps, tracking where one landmark moves. Compare that predicted position against each option instead of judging overall similarity.
