Corrigé de l’EPSO D

Éléments en jeu. A single arrow pivoting inside a fixed square. Track the head's angle from frame to frame and the direction of travel stays constant; the step size is what has to be read off correctly.

Corrigé de l’EPSO C

Éléments en jeu. A diagonally hatched square holding a small cross and a small circle. The hatching is identical in all five frames: both moving parts are the two marks, which travel across the square and swap which of them sits ahead of the other.

Éléments en jeu. One dot walks the perimeter of the frame. The trap is the corners: the spacing between successive positions is even in distance travelled, not in visual displacement.

Corrigé de l’EPSO D

Éléments en jeu. A two-by-two grid holding three symbols, an open circle, a triangle and a filled dot, with one cell left empty in every frame. Nothing is added or removed: the symbols change cells, so the rule is the order they cycle through. EPSO reused this item in three separate publications, which makes it the most widely reprinted official abstract item in existence.

Corrigé de l’EPSO C

Éléments en jeu. A long arrow that turns from frame to frame while a single small circle moves between the corners of the square. Two independent cycles, the arrow's direction and the corner the circle occupies, and nothing accumulates: there is exactly one circle in every frame.

Corrigé de l’EPSO C

Éléments en jeu. A two-by-three block of chevrons. Each frame flips a subset of them; the governing rule is which subset, not how many.

Corrigé de l’EPSO C

Éléments en jeu. A stepped ledge line that lengthens and shifts. The vertical and horizontal components advance independently, so reading only the silhouette is not enough.

Corrigé de l’EPSO E

Éléments en jeu. A quartered square with a second, smaller square overlapping it off-centre. The nesting never deepens, there are two squares throughout. What moves is the inner square's position and, with it, one solid black cell and one hatched cell shifting around the quarters.

Corrigé de l’EPSO C

Éléments en jeu. A diagonal band crossed by small shapes. The band's angle is fixed; what changes is which shapes sit on which side of it.

Corrigé de l’EPSO A

Éléments en jeu. Two circles, one above the other, in a fixed panel. The upper one carries an arrow that turns; the lower one carries a straight line that turns on its own cycle and is absent altogether in some frames. The circles themselves never move, so there is no relation between them to read, only the two rotations.

Corrigé de l’EPSO B

Éléments en jeu. Shapes that alternate outline and fill while shifting position. Alternation and translation run on different periods.

Corrigé de l’EPSO E

Éléments en jeu. A circle at the centre of a straight arm, carrying a square at one end and an arrowhead at the other. The set of pieces never grows: what changes is the arm's orientation and which end each piece occupies.

Corrigé de l’EPSO B

Éléments en jeu. Pinwheel forms with distinct textures per blade. The rotation is obvious; the texture sequence carried around with it is the actual rule.

Corrigé de l’EPSO C

Éléments en jeu. Three rows of wavy arrows. Each row advances on its own, and the answer depends on reading all three rather than the most eye-catching one.

Corrigé de l’EPSO A

Éléments en jeu. A three-by-three grid whose middle column is hatched. That column never moves, only the direction of its hatching changes, vertical in the early frames and horizontal later. The outer columns hold one small shape each, always placed symmetrically about the centre of the grid, and their row, their outline-or-solid state and which shape sits on which side all change from frame to frame.

Corrigé de l’EPSO D

Éléments en jeu. Five vertical bars of equal height, each either white or dark. Height never varies at all: the rule is entirely in which bars are shaded and how that pattern shifts along the row.

Corrigé de l’EPSO D

Éléments en jeu. The first item of the 2009 DIT_6 booklet, published when abstract reasoning entered the competition. Identical figure in the English, French and German editions.

Corrigé de l’EPSO B

Éléments en jeu. Second booklet item. The older figures are line-drawn at lower resolution than the current set but follow exactly the same five-frame, five-option format.

Corrigé de l’EPSO B

Éléments en jeu. Third and last booklet item. EPSO published only three legacy examples in total, against ten in each current set.

Éléments en jeu. Screen three of the retired computer-based-testing walkthrough, shown inside a replica of the Prometric interface candidates actually sat. The demo carried no answer sheet, so this is the only official EPSO abstract item with no published key.
