This thesis explores the relationship between numerical cognition and motor processes in children, with a focus on the interaction between numerical magnitude and action-related judgments. The study builds on the findings of Badets et al. (2007) that irrelevant numbers can influence graspability judgments in adults. This study wants to know whether a comparable effect occurs in school-aged children. A total of 51 children between the ages of 6 and 10 participated in a computerized task in which they had to judge the graspability of rods of different lengths presented after numerical primes (small: 2–3; large: 7–8). Standardized tests of numerical competence (e.g., AC-MT), fine motor skills (e.g., ABC battery), and finger gnosis were also administered. The results determine if numerical primes systematically influence children’s graspability judgments and if this effect is affected by developmental factors, such as age, numerical ability, and motor skills. This study contributes to the growing field of embodied numerical cognition by examining how children's understanding of numbers changes over time and how this change depends on the sensorimotor systems
Questa tesi indaga il rapporto tra cognizione numerica e processi motori nei bambini, concentrandosi in particolare sull’interazione tra la grandezza numerica e i giudizi legati all’azione. Il lavoro prende avvio dagli studi di Badets et al. (2007), secondo cui numeri irrilevanti possono influenzare i giudizi di afferrabilità negli adulti. L’obiettivo della ricerca è comprendere se un effetto analogo si manifesti anche nei bambini in età scolare. Hanno partecipato allo studio 51 bambini tra i 6 e i 10 anni, coinvolti in un compito computerizzato in cui dovevano giudicare l’afferrabilità di bastoncini di diversa lunghezza, presentati dopo un numero priming (piccolo: 2–3; grande: 7–8). Oltre al compito sperimentale, sono stati somministrati test standardizzati per valutare le competenze numeriche (AC-MT), le abilità motorie fini (batteria ABC) e la finger gnosis. I risultati permettono di valutare se i numeri priming influenzano in modo sistematico i giudizi di afferrabilità nei bambini e se tale effetto sia modulato da fattori evolutivi come l’età, le abilità numeriche e quelle motorie. La presente ricerca si inserisce nel più ampio filone della cognizione numerica incarnata, contribuendo alla comprensione di come si sviluppi la rappresentazione simbolica dei numeri e di quanto tale sviluppo dipenda dall’integrazione con i sistemi sensomotori.

Abstract
This thesis explores the relationship between numerical cognition and motor processes in children, with a focus on the interaction between numerical magnitude and action-related judgments. The study builds on the findings of Badets et al. (2007) that irrelevant numbers can influence graspability judgments in adults. This study wants to know whether a comparable effect occurs in school-aged children. A total of 51 children between the ages of 6 and 10 participated in a computerized task in which they had to judge the graspability of rods of different lengths presented after numerical primes (small: 2–3; large: 7–8). Standardized tests of numerical competence (e.g., AC-MT), fine motor skills (e.g., ABC battery), and finger gnosis were also administered. The results determine if numerical primes systematically influence children’s graspability judgments and if this effect is affected by developmental factors, such as age, numerical ability, and motor skills.
