However, this model does not predict format effects on the mechanisms of calculation since each format, number words or Arabic digits, is transferred to a verbal code before calculation starts (Noel, Fias, & Brysbaert, 1997), mainly for overlearned calculations such as single-digit addition and multiplication problems (but not for subtraction problems, in which a magnitude code is used).
But, what is important in the context of this article is that different studies have shown that PSE is larger when operands are presented as number words than when presented in Arabic digits format (e.
In other words, we aim at exploring whether format effects also occur after the potential visual familiarity of Arabic digits format is removed.
In light of these considerations, we designed arithmetic word problems with two types of operands or format, Arabic digits and number words, within two problem-size categories (large vs.
Arabic digits or number words are ways of perceiving or expressing a given quantity, but the central processes--such as calculating, or deciding which of two numbers is the largest--take place in an amodal semantic representation that acts as a bottleneck between input and output stages.
Thus, for instance, if a multiplication such as 3 x 4 is presented as Arabic digits, it has to be transcoded into a verbal format before the result can be retrieved.
Subsequently, calculation is said to take place mainly in Arabic digits (Campbell, 1994; Campbell & Clark, 1992): therefore, this code will also facilitate access to the results of arithmetical operations.
Neither are there data in support of the notion that Arabic digits is the most common format in calculation, as claimed by Campbell et al.
In the test set B, The training set contained 10 utterances of the Arabic digits each from 60 speakers (31 male and 29 female) comprising a total of 6000 utterances, and the test set contained isolated digits from 30 other speakers (15 male and 15 female) for a total of 3000 utterances.
Arabic Number Comparison: Two Arabic digits from 1 to 9 (Arial, 48-point font) were presented on the computer screen and children were asked to select the largest digit in numerical size.
Physical Size Comparison: Children were presented with two identical Arabic digits (on a white screen) and were asked to select the largest digit in physical size (e.
Stroop task: Children were presented with pairs of Arabic digits (1-9) varying along two dimensions: physical and numerical size.
