This is the ability to understand visual information and recreate it. It requires fine motor skills, hand-eye coordination, and the ability to see how parts fit together to make a whole.
Compares the minimal number of moves needed to complete a design vs. the user’s actual moves. Low efficiency = impulsive or non-strategic approach. wechsler block design test
However, psychologists also look at how the participant solves the puzzle, not just the score: This is the ability to understand visual information
Measures how well the user recovers when the system intentionally disrupts the design mid-way (e.g., shaking the table in simulation). Mimics real-world problem-solving under interruption. wechsler block design test
