                ASSESSMENT OF PERCEPTUAL FOUNDATIONS OF READING
PHONEME AWARENESS
Letters stand for speech sounds. Speech sounds are produced and perceived based on the way they are made, i.e., the way they are articulated. The skill of reading requires the ability break apart the steady flow of sounds in speech into units that line up with letter sounds.
This is Harder than you Think
Sounds of speech are coarticulated and overlap each other.  The sound of a letter changes depending on its syllabic context:
  • d in dog  vs  d in dig
  • c in cat   vs  c in cot
  • i in slip   vs   i in slid

Some sounds are hard hear. Like:   
  • n in "among"
      
  • l  in "silk"
Some sounds are easy to confuse with other sounds. Like:
  • v vs f

  • b vs p

  • g vs k
GENERAL PHONOLOGICAL PROCESSING
     In order to hear phoneme level sounds correctly, there needs to be a more general ability to perceive speech accurately. Some parts of speech are harder to detect than others:
  • unstressed sounds like word endings and "little" words (is, and, this)
  • 
sounds when there is background noise

  • sounds that are similar to other sounds like ch (in chair) and sh (in shoe)
The ability to manage speech sounds helps other functions besides speech, reading and spelling:
  • finding words efficiently
  • 
using inner language to guide thinking
  • 
using inner language to rehearse in support of working memory
  • 
understanding the parts of grammar indicated in word endings and little words
READING HAS NOT BEEN PROPERLY EVALUATED AND INSTRUCTION CANNOT BE PLANNED UNLESS THESE FUNCTIONS ARE ASSESSED AND UNDERSTOOD
