Highly Imaginable Words and Short Sentences Edition

Highly Imaginable Words and Short Sentences Edition is the next instructional material to be used after the Basic Spelling and Phonics Edition.

This material strengthens and further generalizes the spelling and sound memory, as well as word form memory, learned in the “Basic Spelling and Phonics Edition” through tactile reading of words and sentences featuring uniquely developed depictions designed to activate semantic memory.

The material consists of 22 sentences describing highly imaginative pictures and 11 word lists. Learners alternate between tactile reading of the “pictures and sentences” and the “word lists.”

Our research has shown that tactile reading facilitates the connection between visual representations and phonological representations through the semantic system. This connection strengthens RAN (Rapid Automatized Naming), a foundational cognitive skill for literacy.

In the Highly Imaginable Words and Short Sentences Edition, tactile reading with highly imaginable words, sentences, and pictures aims to strongly activate the semantic system, further enhancing the brain’s reading and spelling network.

Audio-Visual Materials for Tactile reading Learning
These are dedicated audio-visual materials designed for tactile reading learning. English words are first marked up and then read aloud. Learners retain phonological information in their working memory while engaging in tactile reading of the three-dimensionalized words. This learning method strengthens the connection between spelling and sound, enhancing decoding skills.

User Manual and Evaluation Sheets:
Sawaru Glyph has been developed to enable functional training for dyslexia at home. The included instruction manual provides detailed guidance on how to use the materials. Additionally, evaluation sheets are provided to measure changes in reading skills and RAN functionality resulting from Sawaru Glyph. This allows families to conduct scientifically-based training at home.

 

How to Use

The method of tactile reading and the use of audio-visual materials are the same as in the “Basic Spelling and Phonics Edition.” However, in the “Highly Imaginable Words and Short Sentences Edition,” learners first engage in tactile reading of two depiction-based sentences, followed by a word list contained within those sentences.

By reading the depiction-based sentences first and then the accompanying word list, learners can activate semantic memory while further strengthening spelling and sound memory, word form memory, and the integration of visual and phonological representations. Detailed instructions are provided in the manual.

Principles and Effects

 

By utilizing the effects of haptics, Sawaru Glyph promotes fluent reading and enhances four cognitive functions related to letter recall. It helps improve the cognitive vulnerabilities of dyslexia.

Haptics has the following three functions:

1. Haptic feedback enhances attention to the target and strengthens memory traces.
2. Haptics integrates with visual information in the brain to form concrete, multimodal images.
3. Haptics possesses characteristics of both visual representation (parallel) and phonological representation (sequential), serving to connect the two.

By utilizing these functions of haptics, the neural networks involved in reading and writing abilities in the brain are strengthened.

 

1. Formation of a precise and robust mental image of letter shapes

It has been found that not only seeing letters and symbols, but also engaging with them through haptics while seeing promotes awareness of their shapes, enhancing memory images. By utilizing haptics to interact with the letters, attention is more strongly focused on their shapes, making it easier to leave memory traces. Furthermore, research shows that haptics and vision share a common neural basis in the brain and are cognitively integrated. Incorporating haptics allows for multi-sensory memory encoding.

2. Formation of word form memory (chunking)

By receiving haptic feedback on the spelling (sequence of letters) while reading, chunking of letter sequences in memory is promoted. This enables efficient formation of word form memory. Once the word form memory is established in the mind, it becomes easier to read texts.

3. Formation of associative memory between letters and sounds

Dyslexia often involves difficulty in associating letters with sounds. While memory formation between letters and sounds is promoted by reading aloud alone, the process is further enhanced by combining it with the video and audio resources used in the tactile reading program. By providing simultaneous haptic (touch-based) interaction with letters and auditory information, more effective formation of associative memory between letters and sounds is achieved.

4. The Effect of RAN (Rapid Automatized Naming) Enhancement

RAN（Rapid Automatized Naming） refers to the ability to efficiently retrieve and name visual information, such as pictures or numbers. It is known that children with dyslexia tend to have lower naming speed. Sawaru Glyph is the first program in the world to confirm the improvement of RAN through tactile reading practice. A hypothesis suggests that reading meaningful words while engaging in tactile interaction enables the creation of a bypass within the semantic network, linking the visual lexicon associated with letter and word forms and the phonological lexicon tied to spoken words. This bypass improves the recall of letter forms, which serves as a cognitive cue to facilitate the recall of words (phonological information).

 

Technology and Copyrights

Sawaru Glyph is not merely a teaching material for tactile reading of embossed letters.
This tool integrates the following four original technologies to enable effective multisensory learning through the use of haptics:

1. Font Design Optimized for tactile reading
2. Audio-Visual Features for Integrating Spelling and Sound
3. Stepwise tactile reading Program
4. Analysis and Selection of Image-Rich Words

These technologies support effective learning by utilizing fonts designed for tactile reading and developing audio-visual systems that enhance the connection between letters and sounds. Additionally, the words used in the materials are carefully selected to prioritize semantic processing and facilitate the formation of reading and writing networks.
