The Simple View of Reading: Gough and Tunmer Explained

Key Takeaways

• The Simple View of Reading is a formula: Reading Comprehension = Decoding × Language Comprehension. If either skill is zero, comprehension fails.
• Decoding (Word Recognition) is the ability to translate printed words into speech, relying on phonological awareness, phonics knowledge, and sight recognition.
• Language Comprehension is the ability to understand spoken language, including vocabulary, background knowledge, and understanding of sentence structure (syntax).
• The model identifies four reader profiles: Typical (good D, good LC), Dyslexic (poor D, good LC), Hyperlexic (good D, poor LC), and Mixed Difficulties (poor D, poor LC).
• To diagnose a reading issue, assess decoding and language comprehension separately. Use nonsense words to test pure decoding. Read a text aloud to a learner to test decoding-free language comprehension.
• Intervention must be specific. If decoding is the bottleneck, focus on systematic phonics. If language comprehension is weak, focus on vocabulary, background knowledge and structured talk.
• Scarborough's Reading Rope (2001) details the sub-skills woven into Decoding and Language Comprehension, rather than presenting a different theory.

What is the Simple View of Reading?

Gough and Tunmer (1986) proposed the Simple View of Reading. This evidence based model says decoding and language skills produce reading comprehension. It gives educators a clear framework for understanding how a learner reads.

The model is expressed as: Reading Comprehension = Decoding × Language Comprehension. This highlights that successful reading requires proficiency in both. A weakness in one area cannot be compensated for by strength in the other.

This approach allows teachers to diagnose reading issues. Educators understand components (Goodman, 1969; Gough & Tunmer, 1986). They can find the causes of learners' reading problems. Teachers then give specific help (Ehri, 2020), instead of general support.

‍

Why The Formula Matters for Teachers

Gough and Tunmer (1986) say multiplication is key in reading. Additive skills alone will not achieve reading without decoding. This confirms the formula's structure (Gough & Tunmer, 1986).

Because the skills are multiplicative, a weakness in one area impacts the outcome. If either skill is zero, the entire product is zero. A learner who cannot decode any words (Decoding = 0) will have zero reading comprehension, regardless of vocabulary and background knowledge.

This "zero effect" is fundamental. A learner who decodes fluently but has weak language comprehension (e.g., Decoding = 1, Language Comprehension = 0.2) will have poor comprehension (1 x 0.2 = 0.2). Conversely, a learner with excellent language skills but weak decoding (e.g., Decoding = 0.2, Language Comprehension = 1) will also have poor comprehension (0.2 x 1 = 0.2). This helps teachers target the correct intervention.

Decoding (Word Recognition) in the Classroom

Decoding turns written words into speech. This reading skill includes smaller parts. Without quick decoding, learners focus on recognising words. This leaves little focus for comprehension (Sweller, 1988).

What the teacher does: The teacher explicitly teaches systematic synthetic phonics. To assess pure decoding, they present learners with nonsense words (e.g., "vib", "terg", "plom") that follow English phonetic rules. This prevents learners relying on known words.

What the learners do: Learners look at the nonsense words and say the corresponding sounds aloud. For example, seeing "jound", the learner says "/j/ /ou/ /n/ /d/". This demonstrates their ability to apply phonic knowledge to unfamiliar words.

‍

Language Comprehension in the Classroom

Language comprehension means getting meaning from spoken words. Learners need vocabulary, syntax, and background knowledge (Perfetti & Hart, 2001). These non-print skills let learners make meaning from what they hear (Gough & Tunmer, 1986).

Castles, Rastle, and Nation (2018) showed decoding and language skills boost reading. A learner's reading comprehension will not exceed their listening ability.

What the teacher does: To isolate Language Comprehension, the teacher removes the burden of decoding. They select a challenging, age-appropriate text and read it aloud to a learner. They then ask comprehension questions.

What the learners do: The learner listens to the text. They then answer questions requiring inference and understanding of vocabulary and sentence structure. For example, after hearing "The exhausted explorer stumbled towards the oasis," the teacher might ask, "How was the explorer feeling? What does 'oasis' mean here?" The learner's ability to answer reveals their Language Comprehension, independent of decoding skill.

‍

The Four Reading Profiles

The Simple View (Gough & Tunmer, 1986; Hoover & Gough, 1990) offers a helpful grid. Teachers assess a learner's decoding (D) and language comprehension (LC) separately. This places learners into one of four profiles for targeted support.

‍

Profile 1: Typical Readers (Good D, Good LC)

These learners have strong skills in both areas. They decode accurately and have the language skills to understand what they read. They require continued instruction to progress.

‍

Profile 2: Dyslexia (Poor D, Good LC)

Learners with dyslexia struggle to recognise words and spell (Snowling, 2000). They understand well when someone reads to them. Intensive support helps with decoding skills (Lyon et al., 2003).

‍

Profile 3: Hyperlexia (Good D, Poor LC)

"Word callers" can decode text accurately while still struggling to understand what they read. In the Simple View, this points teachers towards language comprehension: vocabulary, background knowledge, inference and connections across the text (Gough & Tunmer, 1986).

What the teacher does: The teacher uses graphic organisers to help learners make connections between different parts of the text. For example, they might use a concept map to link characters, events, and themes. They also explicitly teach vocabulary, pre-teaching key words before reading.

Learners use graphic organisers; they add text details and link ideas. Discussions explore new word meanings (Fisher & Frey, 2008). This helps them understand concepts (Marzano, 2004; Hattie, 2009).

‍

Profile 4: Mixed Difficulties (Poor D, Poor LC)

Research shows these learners need help with decoding and language comprehension. Interventions should target both areas, starting with basic decoding skills (Gough & Tunmer, 1986). Simultaneously, build the learner's spoken vocabulary and background knowledge (Catts et al., 2015; Nation, 2005).

‍

Connection to Scarborough's Reading Rope

Scarborough's Reading Rope (2001) elaborates on the Simple View. It visualises how Decoding and Language Comprehension are made of smaller strands.

Gough and Tunmer (1986) stated "Lower Strands" are word recognition. This covers phonics and instant word identification. "Upper Strands," says Scarborough (2001), are language understanding. These include a learner's knowledge, vocab, and reasoning.

Scarborough's (2001) rope shows learners need different reading skills to start. These skills combine with practice until learners perform them automatically. This model helps teachers see how interventions support reading (Scarborough, 2001).

‍

Common Misconceptions

1. "The Simple View is just about phonics."

Incorrect. The model gives equal weight to Language Comprehension. Phonics is essential for decoding, but it is only half of the equation.

2. "You can add the skills together."

Teachers should understand the multiplicative link (D × LC). Educators may misunderstand if they see skills additively (D + LC). Spoken language might hide decoding issues.

3. "It's a complete reading programme."

The Simple View is a diagnostic framework, not a curriculum. It tells you what needs to be taught by identifying the area of weakness, but it does not prescribe a specific programme or teaching method, other than ensuring the intervention matches the need.

4. "It only applies to young children."

Decoding matters most in primary school. Language comprehension issues emerge later, as texts get harder (Bowyer-Crane et al., 2008). Older learners may have hidden language problems revealed by complex texts (Catts, Adlof, & Weismer, 2006).

‍

Practical Implementation Guide

A teacher can use the Simple View to diagnose a struggling reader with this plan.

Step 1: Create a Hypothesis.

You have a learner, Tom, who reads haltingly and cannot answer basic questions. Your initial hypothesis is that he has a decoding problem, but you need to be sure.

Step 2: Assess Decoding in Isolation.

Use a list of nonsense words. You give Tom a list containing "plood," "snig," and "framble." He struggles, mispronouncing them or guessing. This provides evidence that his decoding (D) is weak.

Step 3: Assess Language Comprehension in Isolation.

Choose a short, engaging text at Tom's chronological age level. You read the text aloud to him, ensuring he is only listening. You then ask him five comprehension questions. He answers four correctly, demonstrating strong oral language and background knowledge. This provides evidence his language comprehension (LC) is strong.

Step 4: Plot the Profile and Plan Intervention.

Tom has decoding challenges but good language skills, fitting the dyslexic profile. Focus on his decoding skills (D), not broad comprehension. Implement systematic synthetic phonics (Torgesen, 2004; Ehri, 2014). Provide targeted support for him (Rose, 2009; Hulme & Snowling, 2013).

The Simple View Across Subjects

Following this, learners must connect the poem to their existing knowledge. Rosenblatt (1978) emphasised the reader's role in creating meaning from the text. Iser (1978) described the process as an interplay between the text and the learner. Fish (1980) claimed interpretation depends on the interpretive community. Learners decode words accurately before analysing poetry. They require language skills for vocabulary, syntax, and figurative language (metaphor, simile). Learners connect the poem to prior knowledge. Rosenblatt (1978) stressed the reader's role in creating meaning. Iser (1978) saw an interplay between text and learner. Fish (1980) argued interpretation depends on community.

What the teacher does: The teacher models how to decode a complex sentence from a poem, breaking it down into smaller parts. They then ask learners to identify examples of figurative language and explain their meaning.

What the learners do: Learners work in pairs to decode and analyse a different sentence from the poem. They then share their findings with the class, explaining the meaning of the sentence and identifying any examples of figurative language.

Maths: A learner reads a word problem: "A shopkeeper has 37 apples and sells 19. How many are left?" They must first decode every word. Then, they need the language comprehension to understand the vocabulary ('sells', 'left') and the syntax that signals a subtraction operation is required.

Decoding lets the learner read instructions (Perfetti & Hart, 2001). Language skills help them understand "saline solution" and "beaker". Prior knowledge explains what these words mean. Understanding "carefully" guides their actions (Cain & Oakhill, 2007).

Common Questions About The Simple View

‍

Is the Simple View of Reading still relevant?

Yes. Research (Hoover & Gough, 1990; Castles, Rastle, & Nation, 2018) has confirmed its validity. It remains the most scientifically robust and practical model of reading for classroom teachers.

‍

How does reading fluency fit into the model?

Researchers have long explored fluency. Accuracy, speed, and expression help learners understand text. Automatic decoding lets brains focus on meaning (Perfetti, 1985). Fluency follows good decoding skills, not a separate skill (LaBerge & Samuels, 1974).

‍

What about older learners in secondary school?

Language comprehension matters increasingly for older learners because subject vocabulary, complex syntax and background knowledge shape whether accurately decoded text makes sense (Cain & Oakhill, 2007; Catts, Adlof, & Weismer, 2006).

‍

Can I use the Simple View for my EAL learners?

The model supports learners with EAL effectively. It helps teachers identify decoding difficulties versus vocabulary needs (Nation, 2001). This helps learners who struggle with English comprehension (Gough & Tunmer, 1986; Hoover & Gough, 1990). Share good practice with colleagues (Scarborough, 2001).

For your next lesson with a struggling reader, remove the decoding demand. Read a challenging text to them and ask questions. Their answers will tell you everything you need to know about the strength of their language comprehension and will show you exactly where to focus your support.
