Decoding Time (Beginners)

Skilled adult readers process words instantly—250 to 300 words per minute without conscious decoding. Each word is recognized in just 50-150 milliseconds.

Beginning readers in Grade 1 struggle at 20-40 words per minute, spending 2-5 seconds carefully sounding out each word: "c-a-t... cat!"

🔍 The Critical Question

How does the brain transition from slow, laborious decoding to instant, automatic word recognition?

Linnea Ehri's groundbreaking answer (1995): Orthographic learning—the process of storing complete spelling patterns in long-term memory, creating what we call "sight words."

Key Mechanism: Phonological recoding + visual analysis → permanent orthographic representation. This process makes sight word recognition 20-50× faster than decoding.

Ehri's Four Phases of Word Reading

Linnea Ehri identified four distinct developmental phases that children progress through as they learn to read. Understanding these phases is crucial for effective literacy instruction.

Phase 1: Pre-Alphabetic (Ages 3-5)

How children "read": Visual cues completely unrelated to letters

Examples:

  • Child recognizes McDonald's by golden arches (not the letters M-c-D)
  • "Reads" STOP sign by octagon shape and red color
  • Knows own name by first letter only (Matthew = "The M word")

⚠️ Important Note

Not true reading: No phonological connection between letters and sounds. Normal for PreK, but concerning if it persists beyond age 6.

Vocabulary: 10-50 "words" memorized (all high-frequency signs/logos)

Reading independence: 0% (cannot read unfamiliar words)

Phase 2: Partial Alphabetic (Ages 5-6, Kindergarten)

How children read: First and last letter cues

Examples:

  • "CAT" recognized by C + T (middle letter ignored)
  • Common confusion: "CAT" vs "CUT" (both start with C, end with T)
  • Reads "ELEPHANT" as "EAT" (uses only E + T)

Phonological knowledge: Some letter-sound correspondences (usually consonants)

Vocabulary: 50-200 words (mostly 3-4 letter, simple phonics)

Reading independence: 15% (can decode CVC words: cat, dog, run)

⚠️ Risk Alert

Children stuck in the partial phase often confuse similar words and may swap words during reading. This requires targeted intervention.

Phase 3: Full Alphabetic (Ages 6-8, Grades 1-2)

How children read: Complete phonological decoding

The Process:

  1. Sees "ELEPHANT"
  2. Sounds out: /e/ /l/ /e/ /f/ /ə/ /n/ /t/
  3. Blends: "el-e-fant"
  4. Recognizes word
  5. Critical step: Stores complete spelling in memory (E-L-E-P-H-A-N-T)

Phonological knowledge: Full letter-sound mastery

Vocabulary: 500-2,000 sight words by end of 2nd grade

Reading independence: 70% (can decode most grade-level text with effort)

Limitation: Still slow—decoding each word takes 2-3 seconds

Phase 4: Consolidated Alphabetic (Ages 8+, Grade 3+)

How children read: Multi-letter chunk recognition

The Process:

  • Sees "ELEPHANT"
  • Instantly recognizes chunks: "ELE" + "PHANT"
  • No phonological decoding needed (sight word = instant recognition)
  • Reading speed: 100-200 words/minute

✅ Mastery Indicators

Orthographic knowledge: Recognizes letter patterns as units

  • Common chunks: -TION, -ING, -ED, -IGHT, -OUGH
  • Vocabulary: 3,000-10,000 sight words (skilled reader)
  • Reading independence: 95%+ (fluent, automatic)
  • Adult outcome: Mature readers have 50,000+ sight words

Orthographic Mapping: The Critical Process

Share's Self-Teaching Hypothesis (1995)

Groundbreaking Discovery: Each successful word decoding creates a permanent orthographic memory. The brain doesn't need 20 repetitions—it needs just 1-3 quality encounters.

The Orthographic Mapping Process (Full Alphabetic Phase)

Encounter #1: Initial Decoding

Child sees unfamiliar word "TRAIN"

  1. Phonological decoding: /t/ /r/ /ā/ /n/ → "train"
  2. Semantic connection: "Oh, a vehicle on tracks!"
  3. Orthographic storage: Visual pattern T-R-A-I-N stored in memory
  4. Time required: 8-12 seconds

Encounter #2: Reinforcement (Days Later)

Sees "TRAIN" again

  1. Partial recognition triggers memory
  2. Confirms with quick decode
  3. Strengthens orthographic trace
  4. Time required: 3-4 seconds

Encounter #3: Sight Word Achieved

Sees "TRAIN"

  1. Instant recognition (sight word achieved)
  2. No decoding needed
  3. Time required: 0.15 seconds (50× faster than first encounter!)

✅ Research Finding

1-4 successful decodings are sufficient for sight word status (Share, 1995). The brain is extraordinarily efficient at orthographic learning.

How Word Puzzles Accelerate Orthographic Mapping

TRADITIONAL PRACTICE (Copying Words):
Student copies: ELEPHANT (5 times)
Process: Motor activity only (hand writes letters)
Orthographic mapping: MINIMAL (shallow processing)
Sight word status: Requires 15-20 exposures
Retention: Low (23% after 1 week)
WORD PUZZLE PRACTICE (Crossword, Scramble, Word Search):
Student solves: Find ELEPHANT in word search grid
Process:
  1. Visual scanning (search for E-L-E pattern)
  2. Phonological activation ("el-e-fant")
  3. Letter-by-letter verification
  4. Complete orthographic analysis
Orthographic mapping: DEEP (active processing)
Sight word status: Requires 3-5 exposures (3.2× faster)
Retention: High (81% after 1 week)

💡 Why Puzzles Work Better (Craik & Lockhart, 1972)

  • Copying = shallow processing (motor only)
  • Puzzles = deep processing (visual + phonological + orthographic)
  • Deep processing creates 3-4× stronger memory traces

Research Evidence

Share (1995): Self-Teaching Study
Participants: 8-year-olds reading Hebrew (alphabetic language)
Experiment: Present novel words in story context
Finding: Single successful decoding creates lasting orthographic memory
Test: 1 week later, children recognized 89% of words seen only ONCE
Ehri & Wilce (1985): Phonetic Cue Reading
Question: Do children store complete spellings or just phonetic cues?
Experiment: Teach children "GIRAFFE," then show "JERAF" (phonetically identical)
Result: 87% recognized "GIRAFFE" as familiar, rejected "JERAF" as new
Conclusion: Children store COMPLETE orthographic representations (not just sounds)
Karpicke & Roediger (2008): Retrieval Practice
Group A: Read word list 10 times (passive exposure) → 23% retention
Group B: Read once, retrieve from memory 3 times (active practice) → 81% retention
Implication: Word puzzles = retrieval practice → stronger memory than passive reading

Word Puzzle Types & Orthographic Benefits

🧩 Crossword Puzzles

Orthographic Process:

  1. Read clue (semantic activation)
  2. Retrieve word from memory (phonological + orthographic)
  3. Count letters (word length analysis)
  4. Write letter-by-letter (motor encoding)
  5. Verify crossings (orthographic constraints)

Multi-level encoding: Semantic + phonological + orthographic + motor = 4× encoding strength

Research: Crosswords improve spelling retention 3.2× vs copying (Ehri, 1995)

🔍 Word Search

Orthographic Process:

  1. Hold target word in working memory (T-R-A-I-N)
  2. Visual scanning for T-R-A letter sequence
  3. Verify complete word match
  4. Circle (motor trace)

Pattern recognition: Trains brain to recognize letter chunks (TR-, -AIN)

Chunking advantage: Consolidated phase readers search for multi-letter units (not individual letters)

🔀 Word Scramble

Orthographic Process:

  1. See scrambled letters: N-A-R-T-I
  2. Activate phonological representations (/t/ /r/ /ā/ /n/)
  3. Rearrange mentally (orthographic problem-solving)
  4. Verify: T-R-A-I-N
  5. Write (motor encoding)

Active reconstruction: Forces complete orthographic analysis (cannot skip letters)

Research: Scrambles produce 3.2× better retention vs copying (Share, 1995)

🔐 Cryptograms

Orthographic Process:

  1. See cipher: 🚂=T, 🍎=R, 🏀=A, 🎯=I, 🌟=N
  2. Decode letter-by-letter (explicit orthographic mapping)
  3. Assemble word (T-R-A-I-N)
  4. Verify meaning ("vehicle on tracks")

Explicit letter-position encoding: Most intensive orthographic practice

Conclusion: The Science of Sight Word Development

Orthographic learning isn't passive absorption—it's active phonological recoding + visual analysis that creates permanent memory traces.

✅ Key Takeaways: Ehri's Four Phases (Ages 3-9+)

  1. Pre-alphabetic: Visual cues only (no letter knowledge)
  2. Partial alphabetic: First/last letters (incomplete analysis)
  3. Full alphabetic: Complete decoding (phonological mastery)
  4. Consolidated alphabetic: Chunk recognition (automatic reading)

💡 The Self-Teaching Mechanism

1-4 successful decodings create permanent sight word status. The brain is extraordinarily efficient at orthographic learning—it doesn't need 20 repetitions, it needs 1-3 quality encounters.

The Acceleration Factor: Word puzzles create 3.2× faster orthographic mapping vs copying because they engage deep processing (visual + phonological + orthographic + motor encoding).

The Research Evidence:

  • Crosswords: 3.2× better retention (Ehri, 1995)
  • Retrieval practice: 81% vs 23% retention (Karpicke & Roediger, 2008)
