How to use the memory aid for confusions b/d p/q
in a dyslexia session?
Complete practical guide — speech therapist's advice for integrating the memory aid for confusions b/d p/q into visual-spatial discrimination work and the automation of grapho-phonemic correspondences
The confusions b/d/p/q are one of the most visible — and most persistent — manifestations of dyslexia. They often crystallize the frustration of families and the misunderstanding of teachers. However, their neurological origin is well documented, and effective rehabilitative strategies exist. The DYNSEO memory aid for confusions b/d p/q is one of the simplest and most effective tools to work on them in session. This guide explains precisely how to use it in your speech therapy practice.
1. Why are the confusions b/d/p/q specific to dyslexia?
Before explaining how to use the memory aid, understanding why these confusions occur specifically in dyslexia — and not just in "young readers" — is fundamental for adapting the care.
🧠 Three mechanisms specific to dyslexia
1. Short-term verbal memory deficit: the dyslexic child struggles to maintain the phonological form of the letter in memory, which weakens the grapheme-phoneme link.
2. Atypical visual-spatial processing: dyslexia is often accompanied by less automated processing of spatial orientations — distinguishing "same shape, different orientation" requires conscious effort.
3. Difficult automation: even when the rule is understood, automation is slow. The memory aid compensates for this deficit in automation by externalizing the rule onto a permanent support.
2. The memory aid in the dyslexia care protocol
The DYNSEO memory aid for confusions b/d p/q is integrated into a structured therapeutic sequence. It is not an isolated tool — it is a piece in a broader rehabilitation protocol for graphemic discrimination.
Identify the dominant type of confusion
Before using the memory aid, identify which pair(s) pose the most problems (b/d? p/q? all four?) and in what direction (b read as d? or d read as b?). This precise mapping guides the choice of priority mnemonic strategies.
Introduce the tool and choose the anchors
Present the memory aid to the child and explore together the proposed mnemonic anchors. Test each method and let the child choose the one that resonates best with them (hand method, keyword, story). The appropriation of the strategy is a condition for its effectiveness.
Practice with the available memory aid
Discrimination exercises, reading words, targeted dictations — always with the memory aid placed on the desk. The goal is not yet autonomy but familiarization: the child must systematically and automatically consult their sheet.
Reduce dependence on the tool
Gradually, reduce the size of the memory aid and increase the distance. The goal is to internalize the anchor — until the letter is recognized without needing to consult the sheet.

3.1 The hand method: the most effective in session
👐 Protocol for the hand method
Extend both hands in front of you, thumbs up. The left hand forms a d (stem to the left of the circle), the right hand forms a b (stem to the right). In session: ask the child to show their hands before each task involving b and d. Gradually, this gesture becomes internal — the child activates it mentally without doing it physically. The hand method is inscribed in the body, not just in the head — which makes it accessible even in reading stress situations.
3.2 Progressive exercises with the memory aid in session
Pure discrimination (memory aid open)
Show an isolated letter — the child consults the memory aid, identifies the corresponding anchor, and names the letter. Gradually increase the speed. This exercise works on the speed of access to the anchor.
Reading targeted words (memory aid available)
Prepare lists of words containing b, d, p, and q in high density. The child reads with the memory aid within reach. Each hesitation leads to a consultation of the sheet — never to a direct verbal correction.
Dictations of targeted words (memory aid available)
Mini-dictations of 10 words containing the confused letters. The memory aid is available but the child must choose whether to consult it or not. Track the consultation rate vs the error rate — a reduction in consultation with maintenance of the success rate indicates the internalization of the anchor.
Reading texts with b/d/p/q highlighted
Prepare a short text where all the letters b, d, p, and q are highlighted in a distinct color. The child reads with the memory aid within reach. The highlighting draws attention to the target letters without interrupting the flow of reading.
Progress data to track: For each session, note the number of b/d/p/q errors out of 20 words, the number of consultations of the memory aid, and the average time to identify a letter. These three indicators allow for precise tracking of automation — beyond just "they make fewer mistakes."
3.3 For home: transmission to parents
- Provide a laminated version of the memory aid to the parents with simple written instructions
- Prescribe 10 minutes a day of reading aloud with the memory aid placed on the desk
- Ask parents to note the letters that still pose problems to calibrate the following sessions
- Encourage parents to use the hand method during homework — without waiting for the next session
- Reminder: correct by repeating the model once, never by insisting or showing impatience
“I systematically test the memory aid in session before giving it to take home. Some children latch onto the keyword, others on the hands. Finding the right key for each child is the work — the DYNSEO memory aid gives me several options to test quickly.”

🎯 The memory aid is not a goal — it is a transitional tool
The therapeutic goal is not for the child to use the memory aid for their whole life — it is for the letters to be sufficiently anchored to be recognized automatically without help. The memory aid is a transitional tool that supports learning during the automation phase. Plan from the beginning a protocol for gradual weaning — and share this goal with the child and family to maintain motivation towards autonomy.

FAQ — Memory aid b/d p/q and dyslexia in session
Q1 At what stage of care should the memory aid be introduced?
The memory aid can be introduced as early as the first sessions — as soon as the b/d/p/q confusions are identified as an obstacle to decoding. It is not necessary to wait until the reading level is "good enough" to use it. On the contrary, introducing it early prevents the confusions from becoming fixed and the child from developing avoidance strategies (skipping unknown words, guessing by context) that mask errors without resolving them.
Q2 How to choose between the hand method, keywords, and memorable story?
Test all three in session and let the child choose. In practice: kinesthetic children prefer the hand method (body anchoring); visual children prefer keywords with associated images; auditory-verbal children remember the memorable story better. For ADHD profiles, the hand method is often preferable as it is available without material support. For ASD profiles, the memo card with visual keywords is generally more suitable as it is predictable and consistent.
Q3 How to manage the case where the child succeeds with the memory aid in session but continues to make mistakes without it?
This is a sign that the anchoring is known but not yet automated — it is a normal step in the process. The solution is to increase practice with the memory aid (not to remove it prematurely) and to add speed exercises: present letters more and more quickly to train automation. Measure the average response time — it gradually decreases as automation progresses, even before errors have completely disappeared.
Q4 Can the memory aid be allowed during national assessments (DNB, Bac) for dyslexic students?
Yes — as part of accommodations for students with disabilities, the b/d p/q confusion memory aid can be mentioned as a compensatory aid in the MDPH file. The speech therapist can write a certificate specifying that this tool is a necessary compensatory accommodation. For the DNB and the Baccalauréat, accommodations are granted by school doctors based on a file including the diagnosis and recommendations from the healthcare professional.
Q5 How to manage the case of a dyslexic teenager or adult who is ashamed to use the memory aid?
Shame is common — especially among teenagers who have suffered from being "different" throughout their schooling. Several strategies: reframe the memory aid as a professional tool ("surgeons use checklists, pilots have checklists — dyslexic readers use memory aids, it's a smart strategy, not a weakness"); offer a discreet version (credit card-sized card in the wallet); work on accepting dyslexia in parallel; and remind that the goal is to no longer need it — the memory aid is temporary.
