The Hidden Contributors to Reading Success: Working Memory & Processing Speed

When a child struggles with reading, most parents naturally focus on the visible skills: phonics, decoding, sight words, or comprehension strategies.

But here’s the part many families don’t hear until much later:

👉 Strong reading depends on more than reading instruction alone.

Two often-overlooked brain skills, working memory and processing speed, quietly play a HUGE role in whether reading feels manageable… or exhausting.

Let’s take a closer look at these “hidden contributors” and why strengthening them can make reading click in a whole new way.

Why Reading Is So Demanding for the Brain

Reading might look automatic for fluent readers, but for developing readers, it’s one of the most cognitively complex tasks the brain performs.

To read smoothly, a child must:

  • Recognize letters and sounds
  • Hold sounds in mind long enough to blend them
  • Process information quickly before it’s forgotten
  • Keep track of meaning across words and sentences

That’s where working memory and processing speed come in.

Working Memory: The Brain’s Mental Sticky Note

Working memory is the ability to hold information in mind while using it, just like you write your verification code down on a sticky note when you’re trying to log in to an account.

In reading, working memory allows a child to:

  • Remember the beginning of a word while finishing the end 
  • Hold sounds in mind long enough to blend them into words
  • Remember what happened at the start of a sentence by the time they reach the end
  • Follow multi-step directions

What it looks like when working memory is weak

Parents often notice:

  • Trouble sounding out longer words
  • Losing place while reading
  • Forgetting what was just read or having to decode a word every time they see it
  • Difficulty answering questions, even when the child did read the passage

To a child, it can feel like the words and meaning are constantly slipping away no matter how hard they try to “focus.”

Processing Speed: How Quickly the Brain Takes In and Uses Information

Processing speed refers to how efficiently the brain understands and responds to information.

In reading, processing speed affects:

  • How quickly letters, sounds, and words are recognized
  • Reading fluency and pace
  • The ability to keep up with classroom reading demands
  • How much mental energy is left for comprehension

What it looks like when processing speed is slow

You might hear or say:

  • “My child reads accurately, but very slowly”
  • “Homework takes forever”
  • “They understand it… eventually”
  • “He has to sound out the word one letter at a time every time he sees it.”

When processing speed is weak, reading often feels laborious (and tiring) because the brain is working overtime just to try to keep up.

Why Reading Instruction Alone Isn’t Always Enough

Many children receive appropriate reading instruction and still struggle.

That’s often because:

  • Reading programs teach what to read
  • But they don’t strengthen the brain skills required to support reading

Research consistently shows that cognitive skills like working memory and processing speed are closely linked to reading fluency and comprehension. When these skills are underdeveloped, progress can stall, even with good instruction and lots of practice.

The Good News: These Skills Can Be Strengthened

At LearningRx Charlottesville, we start with a comprehensive cognitive skills assessment that looks beyond reading level to identify why reading is difficult.

Then, through one-on-one brain training, we target the specific skills each learner needs, often including:

  • Working memory
  • Processing speed
  • Attention
  • Long-term memory
  • Auditory and visual processing
  • And reasoning.

As these foundational skills improve, parents have often noticed:

  • Reading became smoother and less effortful
  • Improved fluency and stamina
  • Better comprehension
  • More confidence—and fewer tears over reading.

When Reading Finally Feels Easier

For many families, the biggest shift isn’t just academic; it’s emotional, too. When the brain skills behind reading get stronger, children often go from: “I hate reading”  to “This isn’t so hard anymore.”

And parents finally get answers that make sense.

Wondering What Might Be Holding Your Child Back?

If your child is struggling with reading or working twice as hard just to keep up, it may not be about effort or motivation.

It may be about hidden cognitive skills that haven’t been strengthened yet.

📍 LearningRx Charlottesville offers cognitive skills assessments that uncover the root causes of reading struggles and create a clear, science-based path forward.
