Signs of hearing problems?
Behavioural signs • Response to sound • Interest in conversation
• Inattentive • Struggle with verbal
instructions
• Ask to repeat • Prefer face-to-face
• Turn volume up • Struggle to hear if there are
back-ground noise
• Unexplained irritability • Pulling, scratching or
complaining about ears • Overly dependent
Language signs • Discriminating between
consonants • Discriminating between vowels • Hearing of soft sounds (sh, s,
f, t, k) • Auditory analysis • Relating graphemes to
phonemes • Better at sight word
recognition than at reading phonemic words
• Struggle with rhyme • Omission of suffixes • Low reading comprehension • Limited vocabulary
Speech signs • Late talkers • Unusual voice quality
• Unusual volume • Faulty pronunciation
• Poor articulation
• Inappropriate answers to questions
What is auditory perception?
When does hearing become auditory perception?
How much of what we hear depends on cognitive processing?
Expectation: What’s that big noise? What pig outdoors?

Connections
Context
Development & delays • Optimal period: pre-natal-6
years
• Delays influence: • Language development
• Social development
• Behaviour and emotional expression
• Academic skills • Intervention programme
includes:
• Listening skills • Auditory perception
• Language skills
Listening skills � Model good listening
� Be clear what is expected while listening
� Get attention
� Realistic opportunities to practise
� Listening lotto
For the teacher: Say what you going to say, say it, summarise what you said
Auditory adaptation Gradual decrease in hearing sensitivity during sustained, fixed level auditory stimulation
Auditory localisation • Determining where a sound is
coming from • Some ideas:
• Auditory treasure hunt
• Listening outside
Auditory segregation and integration • Distinguish sounds coming
from independent sound events
• Integrate sounds that belong together
• Some ideas: • What do you hear?

Auditory recognition and categorisation
� Recognition = detection
� What do you hear?
� Which of these sounds belong together?
� Find the picture for the sound.
� When you hear a “s” jump up…
Auditory discrimination
• Detecting differences in sound
• WEPMAN test
• Easier to detect differences between sounds from different phoneme categories, e.g. b and o
• Do these words start with the same sound?
• Which word is the odd one out?
Auditory analysis and synthesis …and more • Detection and discrimination
first
• Blending: m-a-t= mat • Segmentation: mat=m-a-t
• Deletion: “mat”, if I take the “t” away, what is left?
• Substitution: “mat”, if I change the “m” to a “b”, what do you have?
Auditory memory and sequential
memory
• Recall of what was heard • Echoic memory
• Sensory register for auditory information
• Stored for 3-4 seconds
• Then replaced
• Working memory • Phonological loop
