Abilità matematiche e disturbi del neuro-sviluppo

Ciclo di vita - 26 Aprile 2019

• Cardinality - how big is the number for ex if you show to an an some food it will choose the big one (without counting)
• Ordinality each numb has its position -> the position of the number.
• Order the number - Ordining numb task is strongly linked with math task
• Strong prediction of numb ability
• Look to two magnitude and say which one is the larger -> Do comparison. It is linked to math skills & ordering numbers.
• Which task is best prediction of math ability?
• Number comparison (looks at 2 numb and say which one is bigger)
• Numb ordering ability increases with the age
• Order working memory task - remembers the order of items & items themselves.
• Infants deeply only remember the order of items -> good prediction
• Children with discalculia can't do this task since more robust. Children with high math ability work faster.
• Mental number line good prediction of math ability
• Also imagine events are time one after the other
• Study 1
• " 2 young children (primary school)
• " 3 9-11 children discalculia

• Cardinality - how big is the number for ex if you show to an an some food it will choose the big one (without counting).
• Ordinality each numb. has its position -> the position of the number.
• Order the number - Ordering numb. task is strongly co related with math task.
• Strong prediction of numb. ability.
• Look to two magnitude and say which one is the larger -> Do comparison - It is linked to math skills & ordering numbers.
• Which task is best prediction of math ability? -> Number comparison (look at 2 numb and say which one is bigger).
• Numb. ordering ability increases with the age.
• Order working memory task remembers the order of items & items themselves. Infants already only remember the order of items -> good prediction.
• Children with discalculia can't do this task never mind numbers. Children with high math ability work faster.
• Mental number line good prediction of math ability. (also imagine events and time one after the other)
• Study 1 " 2 young children (primary school).
• " 3 9-11 children discalculia.

Correlation between mathematics skills

fo (...) prob. and number line

• comparison
• ordering

month comparison → strong predictor

ordering → but not so strong

fluid intelligence

Object visualizing

w/o comparison → Arithmetic skills

w/o ordering → more 'important' prediction

share same component

month → no ordering (→ art skills)

Study 2

1984 Friedman preschool children have an idea of

familiar daily event: (breakf. before lunch ok;

xmas before Easter no)

No good order proc → problem in maths

1. Parental order processing questionnaire
2. Ordering task (put item in correct order)
3. No ordering
4. Daily events ordering task → accurate →
   • additional measures. Ordering skills the most related
