Amplitud de Conteo

Counting Span (Case, Kurland & Goldberg, 1982) is a complex working memory task that loads both processing (counting) and storage (the running list of counts).

Each round shows multiple arrays — you count, hold, count again, hold the previous count too. At the end, recall all counts in order.

Strongly correlated with reading comprehension and fluid reasoning.

Average adult span is 3-4. Above 5 is exceptional.

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.

1. Watch the array — count only the BLUE dots.
2. Remember the count.
3. Next array appears — count its blue dots, remember the new count too.
4. At the end, type all counts in order, comma-separated.
