Number Comparison

Replication of the study by Buckley & Gillman (1974) investigating whether digits and dot patterns are compared numerically through the same cognitive process.

Participants are shown two stimuli side-by-side and press a button to indicate which is numerically larger. The key predictions are:

• Distance effect (Moyer-Landauer): reaction time decreases as the numerical difference between the two values increases.
• Min effect: reaction time increases as the smaller value increases.
• Format comparison: digits are processed faster than dot patterns; irregular dot patterns are slower than random ones.

Stimulus types

Group	Description
Digits	Two Arabic digits (1–9)
Regular dots	Bisymmetric dot patterns (like playing cards)
Irregular dots	Unique fixed dot arrangement per number
Random dots	Dot configuration changes on every trial
