How do we perform arithmetic calculations? 🧠 ⚙️ 🔢
Successful calculation requires retrieving arithmetic facts from long term memory and using conceptual knowledge to correctly execute mathematical procedures.
Acalculia Treatment: Number Transcoding
𝗡𝘂𝗺𝗯𝗲𝗿 𝗧𝗿𝗮𝗻𝘀𝗰𝗼𝗱𝗶𝗻𝗴 is the process in which numbers are "translated" from one format to another (i.e., converting the written word four into the Arabic numeral 4 or the spoken word "four"). 🔢 🗣️ ✍🏼
This skill is deceptively simple, as how we say a number depends on the context it is in (e.g., the number 230 may be said as "two hundred and thirty," while 2:30 PM is said as "two-thirty").
The Neuroscience of Numbers
What are the neural correlates of number processing? 🔍 🧠 🔢
Number processing in the brain is supported by a vast system of brain regions spanning across the cortex. Researchers have found that parietal lobe areas play a significant role in the calculation and processing of numbers, while frontal lobe areas play a critical role in the recall of numerical knowledge and working memory.

Cognitive Models of Numerical Processing
How can number processing be conceptualized? 🔢 🧠
Models of numerical processing are helpful tools for better understanding the types of arithmetic errors made by people with acalculia. While these errors can be seemingly random upon first glance, theoretical models help provide a framework for recognizing why certain errors are made and how treatment can be individualized to best fit the unique needs of our clients.
