When should this dyscalculia test be used?
When should this dyscalculia test be used?
This assessment battery makes it possible to reliably detect the risk of presenting dyscalculia in children 7 years and older and adults.
We recommend using this test for anyone who you may suspect has dyscalculia. The early detection of this learning disorder can help minimize developmental difficulties and start an appropriate intervention program suitable for each profile.
This assessment battery also makes it possible for adults to understand their risk index for having dyscalculia. Many adults have lived their entire lives with dyscalculia and were never aware of the dysfunction. And, while they may have a normal, or even above average IQ, they may have been considered poor students. Without the early detection and proper management of this learning disorder, adults with dyscalculia may have problems at work or in social situations.
Below are some of the most representative symptoms of dyscalculia:
Difficulties with mathematical calculations
People with dyscalculia have trouble processing mathematical language, which makes it difficult to do mathematical processes like adding, subtracting, multiplying, and dividing.
Difficulties recognizing mathematical symbols
People with dyscalculia may confuse symbols like “+” or “-“, which may create problems when using and applying them to mathematical operations.
Problems aligning mathematical operations
It is common to have trouble changing a vertically written math problem horizontally and vice versa. With operations like multiplication or division, someone with dyscalculia may have trouble aligning the right numbers and symbols in order to get the correct answer.
Difficulties understand spoken word problems
May present difficulties remembering the information given in the word problem, which can make it very difficult, or even impossible, to correctly write and carry-out the correct mathematical operation. It is also common to have trouble differentiating relevant and irrelevant information.
General symptoms
Aside from the purely mathematical problems, people living with dyscalculia may also have trouble telling time, they may get lost often, and they may have poor orientation.

Description of the diagnostic criteria questionnaire
Description of the diagnostic criteria questionnaire
Dyscalculia is characterized by a series of clinical signs and symptoms. These indicators can help you understand the risk of someone having this learning disorder. This is why the first part of the Cognitive Assessment for Dyscalculia Patients (CAB-DC) is a questionnaire made of questions that have been adapted to the diagnostic criteria and symptoms of dyscalculia for each age range.
The questions presented here are similar to those that can be found in a diagnostic manual, questionnaire, or evaluation scales. However, they have been simplified to be easily understood by almost any user.
Made up of a series of simple questions that should be answered by a parent or the professional in charge of the assessment. The questionnaire will cover the following domains: Mathematical language (comprehension of the mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Social relationships (caused by frustration and frustration that may these math problems may have caused), Learning and development (dyscalculia is related to different familiar and developmental factors).
A series of simple questions that can be completed by the professional in charge of the evaluation or by the person taking the test. The questionnaire will cover the following domains: Mathematical language (comprehension of mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Academic history (due to the relation between dyscalculia and academic failure), Professional and social areas (difficulties with the relationship of calculations and daily life).

The presence of alteration in some specific cognitive skills may be indicators of dyscalculia. A general profile of the cognitive skills may indicate how severe the alterations are. Problems with calculations, academic difficulty, and social and emotional problems may be caused by deficits in different cognitive skills. These are the domains and cognitive skills evaluated in the dyscalculia test (CAB-DC):
Attention
Ability to filter distractions and focus on relevant information.Excellent
8.0% above average
Focused attention and dyscalculia. Focused attention is the ability to focus attention on a target stimulus, regardless of how long. We use focused attention in class or doing homework. When distracted, it’s possible to miss important information, which makes it more difficult to correctly complete math equations.

Inhibition, or inhibitory control, is defined as the ability for a human to inhibit or control their impulsive or automatic responses and generate responses mediated by concentration and reasoning. Inhibition has been described in some studies as one of the cognitive abilities most closely associated with mathematical issues; in this way, insufficient inhibition has been linked to dyscalculia.

Our Digital Cognitive Assessments
CogniFit digital tests are designed to measure a specific areas of cognition and are grouped together to form customized batteries based on the unique requirements of the study design and population. Learn more about our different tests and how they can support the unique needs of your study by exploring the details and demos below.
The Speed Test REST-HECOOR exercise was inspired by the classic test of Fingertip tapping from the assessment battery NEPSY (Korkman et al., 1998). The test-taker is required to keep on clicking for 10 seconds and as rapidly as possible with the mouse, or finger if using a touch-screen device, in a defined area on the screen. Data is collected as the number of clicks during the allocated time, number of clicks inside the defined area and number of clicks outside it.
The Resolution Test REST-SPER was inspired by the classic paradigms Go/No Go Task (Gordon & Caramazza, 1982), Continuous Performance Test (Conners, 1989; Epstein et al., 2001), and the Psychomotor Vigilance Task (Dinges & Powell, 1985). The test-taker is required to rapidly press on circles which appear on the screen and to ignore hexagons should they also appear. Embedded in the task are 16 circles-only items and 8 circles-and-hexagons items. For each item data is collected on response time, response accuracy and cursor distance from target center.
Visual Working Memory Span Test
The Concentration Test VISMEM-PLAN took as a reference the Corsi block-tapping test (Corsi, 1972; Kessels et al., 2000; Wechsler, 1945). In the first part of the task, some circles, within a fixed array of circles, light up. The test-taker is required to memorize which circles, within the array, have lit up and then try to reproduce the sequence in the right order. In the second part of the task, a delay of 4 secs is added between the first screen and the playback screen, in order to increase the time the user must retain the information.
The Decoding Test VIPER-NAM was inspired by the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). The test-taker is required to click on the first letter, among four of them, that spells the name of the object depicted on the screen. For example, for the picture of an apple, the test-taker should click on the letter “A” but not on the three incorrect responses (C, P, M) also present on the screen.
Multimodal Lexical Memory Test
The Identification Test COM-NAM is based on the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). For each object shown, the test-taker must choose from three possibilities: 1) the item is presented for the first time in the task or 2) the last time it appeared the item was spoken or 3) the last time it appeared the item was presented as a picture.
The Sequencing Test WOM-ASM is based on the classic direct and indirect digit test of the WAIS-III (Wechsler, 1997). The test-taker is required to remember and reproduce increasingly longer number sequences, which appear, each in its turn, on the screen. The task will begin with a two- -number sequence.
The Equivalencies Test INH-REST was based on the classic Stroop test (Stroop, 1935). The test-taker is asked to press on the spacebar (go action) only if the color names on the screen are printed in the matching color and to refrain from pressing (no-go) if the color of the letters does not match the printed color name.
The Recognition Test WOM-REST is based on the classic tests of Symbol search (WAIS) (Wechsler, 1997), Wisconsin Card Sorting Test (WCST) (Heaton, 1981) and Raven's Progressive Matrices Test (Raven, 1936). In this task, a trio-sequence of objects is presented in the center of the screen. The test-taker is required to memorize these stimuli in a first screen, and to recognize it from among four trio-sequences in a second screen. The number of correct answers is considered to calculate an accuracy percentage.
