Spatial and Speeded Processing - Block Counting, Rotated Blocks, Hidden Figures, Table Reading, Aviation and Instrument Comprehension, Physical Science
Speed with accuracy
This domain mixes spatial visualization and rapid data/instrument reading. Block Counting: count visible cubes, then add hidden cubes needed to support cubes above them; a stack cannot float. Rotated Blocks: track one distinctive feature through the rotation; a mirror image is not a rotation. Hidden Figures: scan for the exact target shape, including embedded lines and shared edges, not just the overall outline. Table Reading: read row and column headers first, locate the intersection, and watch for units, negative values, and rows that shift by one. Instrument Comprehension: relate attitude indicator (pitch/bank), heading indicator, altimeter, airspeed, turn coordinator, and vertical speed; avoid reversing bank or pitch. Physical Science: focus on units, Newton's laws, simple machines, energy conservation, density/pressure, and basic circuits.
Worked example: A block stack shows a cube on the second level with nothing directly beneath it in the drawing. Count one hidden cube under it, because the upper cube must be supported; do not count empty space. Rule of thumb: in block counting, count by columns and add hidden supports; in table reading, point to the row and column with a mental marker before reading the cell.
Trap: time pressure encourages skipping the header or assuming a shape is present because its outline is similar. Answer every item-there is no penalty for guessing-but mark uncertain ones and return only if time remains.
