Beralih antara dua aturan yang diterapkan pada digit yang sama.
Task switching measures cognitive flexibility — your ability to reconfigure mental rules quickly.
The same digit has two possible responses depending on the current rule (parity vs magnitude).
When the rule changes from the previous trial, responses slow — that slowdown is the switch cost.
Smaller switch costs are associated with better multitasking under high load.
Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.
Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.
