Alternative schemes for representing numerical magnitude.:
- A. Barcode magnitude representation (Viscuso et al., 1989; Anderson et al., 1994; McCloskey & Lindemann, 1992).
- B. Numerosity code (Zorzi & Butterworth, 1999).
- C. Compressed number line (logarithmic scale and fixed variance, e.g., Dehaene, 2001, 2003).
- D. Linear number line with scalar variability (e.g., Gallistel & Gelman, 2002; Dehaene, 2001).
