  • Neuropsychological assessment for dyscalculia

  • Explore the areas of the brain most associated with dyscalculia.

  • Assess the possible presence of cognitive deficits

The Cognitive Assessment Battery for Dyscalculia (CAB-DC) was created by a group of specialists in psychology and neuropsychology for the detection and diagnosis of dyscalculia.

This tool provides a series of tasks that assess the cognitive level of each user. It is designed to help all healthcare professionals detect the symptoms of dyscalculia. The professional will receive a full report about the cognitive profile of the patient in order to detect possible cognitive deficits.

When the user finishes the assessment, the CogniFit program uses sophisticated algorithms to collect the results and create a computerized report. This report will provide data on each of the measured cognitive skills, using graphs and tables, so both the professional and the user can easily understand the results and see which cognitive skills are most affected by the learning disorder.

The cognitive assessment for dyscalculia is made up of various blocks of tasks. Each one will assess two or more cognitive skills that may be affected by dyscalculia.

  • Memory area: Working memory and short-term memory.
  • Attention area: Focus, divided attention, and naming.
  • Perception area: Recognition.
  • Coordination area: Response time.
  • Reasoning area: Planning and processing speed.

Neuropsychological areas analyzed and their relation to dyscalculia

Scientific documentation: validated battery of tasks

The neuropsychological battery for dyscalculia was created by using the most recent studies about dyscalculia.

Through different studies, CogniFit's neurocognitive program received satisfactory results. This validation was carried out by a medical clinic to gather reliability data. The results were excellent, with scores between .7 and .8.

Every pathology addressed by CogniFit is associated with a group of cognitive skills that may be affected depending on the patient/user. The assessment will evaluate the cognitive skills that, according to scientific literature, are most affected by dyscalculia. They are the following:

MEMORY Some of the areas of the brain in a child with dyscalculia are different than the brain of a child without it. These areas are directly related to memory and remembering math information, which is why it's so important to work memory areas.

Working Memory and Dyscalculia:

Assessing working memory will give the professional some information about a possible diagnosis. Working memory is important when learning math concepts and learning how to bring them to an abstract idea. Poor working memory causes difficulty following directions, doing mental math, and even forming complete memories.

Short-Term Memory and Dyscalculia:

Children with dyscalculia have problems when doing math problems like multiplication, where they have to remember multiplication tables. This is one of the reasons why short-term memory is evaluated in the assessment.

ATTENTION: There are various studies that confirm that dyscalculia is associated with ADHD in 32% of cases. Assessing attention is important because it is one of the most important areas used in learning new mathematical ideas.

Focus and Dyscalculia:

For a child with dyscalculia to be able to learn math well, they will need to develop their ability to concentrate and focus. Concentration or focus is the time that a child is able to pay attention to a stimulus without getting distracted. It will be important for the optimal acquisition of math.

Divided Attention and Dyscalculia:

Children with dyscalculia have a hard time giving all their attention to something related to math. When the child lacks motivation to learn, their attention tends to be sporadic and it is difficult for them to focus only on one task.

Naming and Dyscalculia:

Being able to recognize mathematical symbols is linked to being able to name them and describe what they do. Assessing recognition makes it possible for the professional to discard a possible diagnosis.

PERCEPTION: Children with dyscalculia have problems with spatial and visual-motor perception, social and emotional areas, as well as recognition.

Recognition and Dyscalculia:

Children with dyscalculia tend to have problems recognizing and interpreting different facial expressions and non-verbal cues. Once the child is able to learn the language used in math, they have a hard time recognizing it and identifying its meaning.

COORDINATION: Coordination, especially motor coordination, tends to be awkward and clumsy in children with dyscalculia. The problem starts with the connection between the brain and our movements, which is why writing is especially difficult for children with this learning disorder.

Response Time and Dyscalculia:

Children with dyscalculia have difficulties when processing external information and responding to said information, which means that it takes them longer to process information they've seen or heard.

REASONING: Children with dyscalculia have to follow an alternative thinking process than most other children in order to understand the same information. In other words, the way that they understand the world, specifically the mathematical world, is different than others.

Planning and Dyscalculia:

As children with dyscalculia will have trouble understanding and doing math problems, planning and motivation will also be hard for them. Just doing homework requires planning and following a routine, which implies concentration and memory at the same time

Processing Speed and Dyscalculia:

Response time and processing speed are closely related when it comes to receiving external information. When someone asks a question, a person must first process what the other person wants to say, and then reply with an appropriate answer. This process for a child with dyscalculia will be different and more difficult than it would be for a child without dyscalculia.

Scientific Documentation

The most important part of the CogniFit assessment for dyscalculia is that it was created using visual and auditory stimuli, which makes it more entertaining and simple for the user.

Aside from the assessment for dyscalculia, CogniFit has a cognitive rehabilitation program which is complementary to a cognitive-behavioral therapy. This tool is made up of a set of training programs adapted to the individual characteristics of each user, and trains the cognitive skills most affected by dyscalculia.

Each one of our tasks are prepared to specifically assess one or more cognitive skills. When the user completes the assessment, the program analyzes the results and creates a complete cognitive profile. With this report, the user or professional will be able to see which cognitive skills are weakest and need the most training.

There is also a professional team at CogniFit available to offer a consultation to recommend the best assessment for each person.

There are lots of advantages to trying one of CogniFit's assessments. We study which skills are most affected by each pathology and work specifically to measure and assess those skills that may be affected. The assessment is based on a cognitive model to identify the presence of the symptoms of dyscalculia. It is a method based on scientific evidence and validated by hundreds of subjects.

The main objective of this assessment is to provide useful information to both the user and the professional, using graphs and charts which will allow the professional to identify a possible diagnosis.
