Sequential or parallel decomposed processing of two-digit numbers? Evidence from eye-tracking.
A study investigated the effectiveness of sequential and parallel decomposition models in predicting the fixation pattern in a two-digit number magnitude comparison task. These models were tested by examining participants' eye fixation behavior while choosing the larger of two numbers. The stimulu...

These models were tested by examining participants' eye fixation behavior while choosing the larger of two numbers. The stimulus set was composed of within-decade and between-decade comparisons, with the latter further split into compatible and incompatible trials and trials with different decade and unit distances. The observed fixation pattern suggested that the comparison of two-digit numbers were not performed by sequentially comparing decade and unit digits as proposed by Poltrock and Schwartz but rather in a decomposed but parallel manner. In addition, the fixation data provided first evidence that digit processing in multi-digit numbers is not an unadulterated bottom-up effect but is also affected by top-down factors. Implications for multi-digit number processing are discussed. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
