q2 i? Adults in cultures with limited number lexicons and no counting system, and deaf adults with number signs not embedded in a counting system, do not develop exact representations of large numerosities. → Noël M-P and Rousselle L 2011

Evidence¶

Noël M-P and Rousselle L 2011¶

Noël M-P and Rousselle L (2011) Developmental changes in the profiles of dyscalculia: an explanation based on a double exact-and-approximate number representation model. Front. Hum. Neurosci. 5:165. https://doi.org/10.3389/fnhum.2011.00165

The review cites cross-cultural studies (Gordon, 2004; Pica et al., 2004) and, separately, deaf adults with home-sign number systems (Spaepen et al., 2011), attributing these findings to those works; the review's own synthesis reports the pattern without effect sizes.

"adults leaving in cultures with very limited number lexicon and no counting system are unable to develop an exact representa- tion of numbers beyond 3 or 4, although their ANS is quite normal (Gordon, 2004; Pica et al., 2004 )"

Discussion¶

Learner Variables¶

• Number Sense — outcome: instruction changes it

• Linguistic delay may affect verbal mathematical abilities without impairing conceptual counting development, as deaf children's one-to-one correspondence understanding was age-appropriate — related
• In object counting, deaf and hearing children make similar attention and principle errors, but deaf children make more number-string errors — related
• Deaf children produce shorter conventional number strings in abstract counting than hearing children of the same school level, with a roughly 2-year delay — related
• Deaf children's abstract-counting errors reflect the rule-bound base-5 structure of Belgian French Sign Language: they stop at production-rule boundaries and make fewer omission errors than hearing children — related
• Deaf and hearing children do not differ in accuracy of object counting or creating sets of a given cardinality up to 14 items — related
• ANS acuity correlates with later number sets fluency but does not emerge as a unique predictor once symbolic knowledge is controlled — related
