Edublox Online Tutor (EOT) houses several multisensory cognitive training programs to enhance cognitive skills such as attention, visual memory, auditory memory, and logical thinking. EOT also provides a free online assessment to measure several cognitive skills, specifically visual sequential memory, auditory memory, iconic memory, and logical reasoning. Sixty-four Grade 2 students of an inner-city school took the test, after which their test scores were correlated with their academic grades using the Pearson Correlation.
What are cognitive skills?
The word “cognition” is defined as “the act or process of knowing”. Cognitive skills, therefore, refer to those skills that make it possible for us to know. They have more to do with the mechanisms of how we learn rather than with any actual knowledge. Cognitive skills include perception, attention, memory, and logical reasoning.
Sensation is the pickup of information by our sensory receptors, for example, the eyes, ears, skin, nostrils, and tongue. In vision, sensation occurs as rays of light are collected by the two eyes and focused on the retina. In hearing, sensation occurs as waves of pulsating air are collected by the outer ear and transmitted through the bones of the middle ear to the cochlear nerve.
On the other hand, perception (also called processing) is the interpretation of what is sensed. The physical events transmitted to the retina may be interpreted as a particular color, pattern, or shape. The physical events picked up by the ear may be interpreted as musical sounds, a human voice, noise, and so forth. In essence, then, perception means interpretation.
Visual perception refers to the brain’s ability to make sense of what the eyes see, while auditory perception is the ability to identify, interpret, and attach meaning to sound. A lack of experience may cause a person to misinterpret what he has seen or heard. In other words, perception represents our apprehension of a present situation in terms of our past experiences, or, as stated by the philosopher Immanuel Kant in Critique of Pure Reason (1781): “We see things not as they are but as we are.”
The process of perception is very much affected by attention, a phenomenon that involves filtering incoming stimuli. Human beings do not pay attention to everything in their environments nor attend to all the stimuli impinging on their sense organs. Rather than becoming overwhelmed by the enormous complexity of the physical world, we attend to some stimuli and do not notice others. William James (1842-1910) recognized the importance of attention very early. “A thing may be present to a man a hundred times, but if he persistently fails to notice it, it cannot be said to enter his experience,” he wrote in his book Psychology: The Briefer Course.
Attention can be divided into focused, sustained, and divided attention. Focused attention enables one to stay focused on a task despite distractions and sustained attention to stay focused for a sustained period of time. Divided attention is a higher-level skill where one has to perform two (or more) tasks simultaneously, and attention is required to perform both (or all) the tasks.

Divided attention is a higher-level skill where one has to perform two (or more) tasks at the same time, and attention is required for the performance of both (or all) the tasks.
Memory is the process by which knowledge is encoded, stored, and later retrieved. Although the word memory may conjure up an image of a singular, “all-or-none” process, it is clear that there are actually many kinds of memory, each of which may be somewhat independent of the others.
The distinction between short-term memory and working memory is an ongoing debate, and the terms are often used interchangeably. Some scholars claim that some kind of manipulation of remembered information is needed to qualify the task as one of working memory. Repeating digits in the same order they were presented would thus be a short-term memory task while repeating them backward would be a working memory task.
Another viewpoint is that of Nelson Cowan, who says short-term memory refers to the passive storage of information when rehearsal is prevented with a storage capacity of around four items. When rehearsal is allowed and controlled attention is involved, it is a working memory task, and the capacity is closer to seven items.
When it comes to memory, one’s senses are involved too. Visual memory involves storing and retrieving previously experienced visual sensations and perceptions when the stimuli that initially evoked them are no longer present. Various researchers have stated that as much as eighty percent of all learning occurs through the eye – with visual memory as a crucial aspect of learning.
Auditory memory, on the other hand, involves being able to take in information that is presented orally, process that information, store it in one’s mind, and then recall what one has heard. Basically, it involves the skills of attending, listening, processing, storing, and recalling.
Sequential memory requires items to be recalled in a specific order. In saying the days of the week, months of the year, a telephone number, the alphabet, and in counting, the order of the elements is of paramount importance. Visual sequential memory is the ability to remember things seen in sequence, while auditory sequential memory is the ability to remember things heard in sequence.
Sensory memory is the shortest-term element of memory. It is the ability to retain impressions of sensory information after the original stimuli have ended. It acts as a kind of buffer for stimuli received through the five senses of sight, hearing, smell, taste and touch, which are retained accurately, but very briefly. For example, the ability to look at something and remember what it looked like with just a second of observation is an example of sensory memory. The sensory memory for visual stimuli is sometimes known as the iconic memory, the memory for aural stimuli is known as the echoic memory, and that for touch as the haptic memory.
Logical reasoning is the process of using a rational, systematic series of steps based on sound mathematical procedures and given statements to arrive at a conclusion.
In logic, there are two broad methods of reaching a conclusion, deductive reasoning and inductive reasoning. Deduction begins with a broad truth (the major premise), such as the statement that all men are mortal. This is followed by the minor premise, a more specific statement, such as that Socrates is a man. A conclusion follows: Socrates is mortal. If the major premise is true and the minor premise is true, the conclusion cannot be false.
In inductive reasoning, broad conclusions are drawn from specific observations; data leads to conclusions. If the data shows a tangible pattern, it will support a hypothesis. For example, having seen ten white swans, we could use inductive reasoning to conclude that all swans are white. This hypothesis is easier to disprove than to prove, and the premises are not necessarily true. Still, they are true given the existing evidence and given that one cannot find a situation in which it is not true.
EOT uses colors placed in sequences to develop inductive reasoning skills. The student will, for example, have to add four colors to complete the sequence below:
The importance of strong cognitive skills
Many studies over many decades have shown that cognitive skills determine an individual’s learning ability, according to Oxfordlearning.com, the skills that “separate the good learners from the so-so learners.” When cognitive skills are strong, learning is fast and easy. When cognitive skills are weak, learning becomes a challenge.
Auditory memory crucial for literacy
Research has confirmed that auditory memory plays a crucial role in literacy: It is one area of auditory processing that directly impacts reading, spelling, writing, and math skills. Kurdek and team measured auditory memory in kindergarteners and found readiness in auditory memory predicted later reading and mathematics achievement in fourth grade.
Children with poor auditory memory skills may struggle to recognize sounds and match them to letters – a common symptom of a reading disability or dyslexia.
Research by Plaza et al. found that dyslexic children exhibited a significant deficit in tasks involving auditory memory skills (digit span, unfamiliar word repetition, sentence repetition) compared with their age-mates. Howes et al. compared 24 readers with auditory dyslexia and 21 with visual dyslexia to 90 control group participants and revealed auditory sequential memory impairments for both types of readers with dyslexia and multiple strengths for good readers.
Visual memory critical for math
Research has also confirmed that visual memory, often considered a subset of visual perception rather than a separate skill, plays a crucial role in literacy, especially maths.
One hundred seventy-one children with a mean age of 10.08 years participated in a study by Marjean Kulp et al. The study, conducted at the Ohio State University College of Optometry, was designed to determine whether or not performance on visual perception tests could predict the children with poor current achievement in mathematics. Controls for age and verbal cognitive ability were included in all regression analyses because the failure to control for verbal cognitive ability/intelligence has been a criticism of some literature investigating the relation between visual perception and academic skills. Scholars have argued that a relation between visual perception – a nonverbal cognitive skill – and math achievement is merely due to the confounding effects of verbal cognitive ability/intelligence.
Kulp et al. concluded: “Poor visual perceptual ability is significantly related to poor achievement in mathematics, even when controlling for verbal cognitive ability. Therefore, visual perceptual ability, and particularly visual memory, should be considered to be amongst the skills that are significantly related to mathematics achievement.”
Another investigation of the relation between visual memory and academics was performed in 155 second- through fourth-grade children; the results were published in the journal Optometry and Vision Science. Visual memory ability was assessed with the Test of Visual Perceptual Skills visual memory subtest. The school administered the Otis-Lennon School Ability Test and Stanford Achievement Test. Age and verbal ability were controlled in all regression analyses.
The researchers concluded that poor visual memory ability is significantly related to below-average reading decoding, maths, and overall academic achievement (as measured by the Stanford Achievement Test) in second- through fourth-grade children.
Visual sequential memory linked to reading
Guthrie and team investigated relations between visual sequential memory and reading in 81 typical and 43 disabled readers. The children had normal intelligence and a mean reading grade of 2.5. The mean chronological age of the typical readers was 8.5 years, and the mean of the reading disabled 10.3. Partial correlations between three tests of visual sequential memory and three tests of reading were computed. Significant, positive associations were identified between visual sequential memory and paragraph comprehension, oral reading, and word recognition.
A study by Stanley et al. compared 33 dyslexic and 33 control eight- to 12-year-old children and found the dyslexic children inferior to the controls on tasks involving visual sequential memory and auditory sequential memory.
Iconic memory related to reading ability
Thirty-six 9‐year‐old children were given a test of image persistence in visual sensory (iconic) memory and the Neale Analysis of Reading Ability. In the iconic memory test, the subjects viewed a white disc in a tachistoscope and were required to state whether or not the disc disappeared for a short interval which ranged from 10 ms to 800 ms. The shortest disappearance perceived was taken as a measure of icon persistence. The reading test gave scores for fluency, accuracy, and comprehension.
All three measures of reading performance were found to be significantly related to icon persistence. Short and long image persistence resulted in a reading age on the accuracy score that was, on average, 1.75 years below that for moderate persistence.
Reasoning tied to academic achievement
A study conducted in India by Bhat examined the contribution of six components of reasoning ability (inductive reasoning, deductive reasoning, linear reasoning, conditional reasoning, cause-and-effect reasoning, and analogical reasoning) to explain the variation in academic achievement of 598 class 10th students. The predictive power of various components of reasoning ability for academic achievement was 31.5%.
Out of the six dimensions of reasoning ability, the maximum involvement was reflected by deductive reasoning (with a reliability coefficient of .49), followed by cause and effect reasoning (.26), inductive reasoning (.16), linear reasoning (.05), conditional reasoning (.03) and analogical reasoning (.02) on academic achievement.
Each of our cognitive skills plays an essential part in processing new information. That means if even one of these skills is weak, no matter what kind of information is coming one’s way, grasping, retaining, or using that information is impacted. In fact, most learning challenges are caused by one or more weak cognitive skills.
Edublox and cognitive skills
Edublox started life in 1979 as a school readiness program with only three cognitive exercises and has since been tried and tested by more than 150,000 children and adults in approximately 40 countries through home-based kits, programs, and learning clinics. Although the developers caution that the Edublox system requires long-term use, Edublox programs have shown improvement in cognitive skills over a short period of time.
A one-week Edublox program was presented in Singapore to 27 learners, ages 10 to 12; the control group comprised 25 students. The Center for Evaluation and Assessment in the Faculty of Education at UP analyzed the pre-and post-test results. The results of the study showed a significant improvement in focused attention.
A 2013 study by Dr. Jaidan Mays, an M.Tech student at the University of Johannesburg, found a significant improvement in visual memory – from 6.2 to 7.5 years following an intensive one-week Edublox program of 22.5 hours. Visual memory ability was assessed with the Test of Visual Perceptual Skills visual memory subtest.
Results of a post hoc research study at the University of Pretoria (UP) by Naseehat Dawood as part of her master’s degree in research psychology under the guidance of Professor David Maree, former Head of the Department of Psychology at UP, show that EOT improves auditory memory.
Sixty-four Grade 2 students of an inner-city school in Pretoria were randomly divided into three groups: the first group completed 28 hours of EOT’s Development Tutor over three weeks; a second group was exposed to standard computer games, while a third group continued with schoolwork. Findings suggest that exposure to the Edublox program significantly improved the post-test scores in the processing speed domain.
The same 64 students took the EOT assessment at the start of the study, after which their assessment scores were correlated with their academic grades by SPSS software using the Pearson Correlation test. As in the study by Bhat, contrary to the common practice of using achievement tests to measure academic achievement, real-life academic grades were used as a measure of academic achievement.
EOT assessment and academic achievement
The EOT assessment consists of five subtests: the Visual Sequential Memory test assesses visual sequential memory, the Auditory Memory test auditory memory, the Eye Span test visual sensory (iconic) memory, the Logical Thinking test logical reasoning, and the Reading test reading age. The Reading test was not applied in this study.
Academic grades in South African schools are scaled from 1-7, 7 being “outstanding achievement” and 1 being “not achieved.”.
SCALE: 7. Outstanding achievement – 80 – 100% 6. Meritorious achievement – 70 – 79% 5. Substantial achievement – 60 – 69% 4. Adequate achievement – 50 – 59% 3. Moderate achievement – 40 – 49% 2. Elementary achievement – 30 – 39% 1. Not achieved - 0–29% .
The 64 students’ Term 4 consolidated academic grades were used in this study, which is a score that combines a student’s academic achievement of all four school terms. The academic grades of their four subjects (English language, second language, math, and life skills) were added together to derive at a Total Academic Score.
The students’ scores on the Auditory Memory subtest correlated significantly with their total academic grades (0.01 level), English language grades (0.05 level), and math grades (0.01 level).
The students’ scores on the Visual Sequential Memory subtest correlated significantly with their math grades (0.01 level) and their scores on the Logical Thinking subtest with their English language grades (0.05 level). In contrast, the Eye Span subtest that assesses iconic memory did not correlate with any school subject.
Summary and conclusion
This study confirms the importance of strong cognitive skills for academic achievement; the cognitive skill with the strongest correlation was auditory memory, which correlated significantly with language and math, as well as total academic grades.
The Eye-span subtest, which measures iconic memory, most likely did not correlate with any school subject as iconic memory is a cognitive skill required mainly for reading, and none of the school subjects rely exclusively on reading. English language grades, for example, are also dependent on spelling, writing, handwriting, and oral ability. The same type of reasoning probably applies to the Visual Sequential Memory subtest, which correlated with math grades but not with English language as a whole.
The Logical Thinking subtest correlated with the students’ English language scores but not their math scores. We predict that a correlation between this subtest and math scores will become more and more apparent in the higher school levels as stronger and stronger problem-solving abilities become a growing requirement over and above basic mathematical skills and knowledge. More research, however, will be required to confirm this theory.
