Beyond grapheme-phoneme correspondences

Beyond the first steps in reading and spelling
Peter Bryant
First thoughts
 Orthographies are only partly systems for encoding
the sounds of oral language
 They are also systems for representing deeper
linguistic distinctions, like the “-ed” spelling for past
tense inflections
 Perhaps it is wrong and dangerous for psychologists
and teachers to ignore these deeper regularities,
 Perhaps it would be quite easy to encourage children
to be interested in these regularities and to learn about
them
The view that children are taught GPCs and then
learn everything else for themselves
 Most current models of reading and spelling at word
level argue that children should first acquire the basic
phonological/alphabetic rules-grapheme-phoneme
correspondences (GPCs) with the help of teachers,
 and then can work out the rest of the system for
themselves
 Current approaches to teaching in the UK adopt this
approach too: teach children about phonology and
the alphabet and the children will take care of the
rest of the learning for themselves
 Spelling rules beyond the GPCs are largely ignored
by theorists and teachers alike
Spelling rules beyond alphabetic
correspondences (GPC)
There are at least two kinds of spelling rule beyond
GPCs:
Conditional rules, like:
 the split digraph (hop vs hope),
 other digraphs,
 the /k/ ending
Morphemic spelling rules, like the spelling for the
past tense ending “ed”: kissed, rolled, wanted
Nunes T. & Bryant. P. (2009)
Children’s Reading & Spelling: beyond the first steps
Wiley-Blackwell
Morphemic spelling rules in many languages
(French, English, Greek, Portuguese, Hebrew, Arabic)
 when the same sound is spelled in different ways
for morphemic reasons
fox
education
socks
magician
 when different sounds are spelled in the same way
for morphemic reasons
kissed
rolled
cats
heal
dogs
health
waited
 when spelling represents silent morphemes
la maison
les maisons
Morphemic spelling rules exist……..
 But do people actually use these rules to spell such
words correctly?
 The alternative is that they learn the specific spellings
for each word (word-specific learning)
Three parts to the talk
Despite lack of teaching, children construct
morphemic rules for themselves
Actually that’s not right: many children and adults
don’t construct morphemic rules for themselves
You can teach morphemic rules to all children
English children construct morphemic rules
for themselves: spelling the “-ed” regular past

Generalisations and overgeneralisations of the
“-ed” ending
 many children put “-eds” on the ends of irregular
past verbs (sleped) (71%), and also of non-verbs
(sofed, necsed) (59%) as well as of regular past
verbs (kissed)
 the generalisation to irregular verbs is incorrect but
grammatically appropriate
 the generalisation to non-verbs is incorrect and
inappropriate grammatically

Greek children construct morphemic rules for
themselves: spelling stems and affixes
A study of Greek children’s learning of how to
spell vowel sounds in inflections and in stems
 Greek is a highly regular orthography as far as
reading is concerned
 Spelling is less predictable because there are very few
vowel sounds in Greek, and there is more than one
way of spelling three of the vowels
 e.g. /i/ is represented by: ι , η , ει, οι


/o/ is represented by: ο , ω
/e/ is represented by: ε , αι
 There is no rule for which spelling to adopt for the
vowels in stems, but in inflections the spelling is
determined morphemically

Conclusions from the Chliounaki & Bryant study
Children get to spell inflections correctly in real
words before pseudowords
However in their first two years at school most
children learn the morphemic spelling rules for
inflections pretty well
Cross-lagged correlations between real and pseudoword spelling of inflections suggest a causal
connection:
It is that word-specific learning lays the basis for
inferring the morphemic spelling rules
At this stage we were confident that pretty nearly all
children constructed the basic morphemic spelling
rules by themselves
Many English people don’t construct some of
the morphemic spelling rules for themselves
Do children learn the morphemic spelling rule
about the English plural ending?
 In English one of the most basic morphemic
spelling rules is that the last sound in buns and
dogs is /z/ but it is spelled as “s” because “s” is the
spelling for the plural morpheme in English
 but there is also a non-morphemic, frequency rule:
which can account for the spelling of many words
ending in /z/. In almost every word that ends in
a /z/ which is preceded by a consonant, the /z/
ending is spelled as “s”: dogs, bastards
 Exceptions are rare words : adze, bronze

2nd experiment – on /z/ and /ks/ ending words
 The Kemp & Bryant result with adults was so surprising
that we decided to extend the /z/ end sound data to onemorpheme vs two-morpheme verbs as well (praise, plays:
sneeze, sees) and also nouns and verbs ending in /ks/
 In this experiment, with 18-25 year old military recruits,
we used pseudo-words, as well as a real word control, and
we gave them a choice between two spellings

Conclusions from English and Greek studies
 The developmental process of children inferring rules
on the basis of their word-specific knowledge seems
to work better for Greek than for English children
 It also works much better for some English
individuals than for others, probably for cultural
reasons
 The reason for the striking individual differences in
the English-speaking populations may be partly due
to differences in exposure to text
 They are probably also due to the lack of explicit
teaching about morphemic spelling rules
You can teach morphemic rules to all
children

Conclusions
 The ‘phonology plus word-specific knowledge’
approach is inadequate: children to some extent do
learn spelling rules: and they NEED to
 Greek children learn about morphemic rules for
themselves with the help of word-specific knowledge,
but English children don’t do so well
 Some English children/adults acquire explicit and
effective knowledge of morphemic spelling rules:
others have a much weaker knowledge of these rules
 The reasons for these differences among English
children are probably cultural
 These sharp individual differences would almost
certainly disappear if children were taught about
spelling rules systematically and entertainingly
Final thoughts
 Orthographies are only partly systems for encoding
the sounds of oral language
 They are also systems for representing deeper
linguistic distinctions, like the “-ed” spelling for past
tense inflections
 Our evidence suggests (1) that it is wrong and
dangerous for psychologists and teachers to ignore
these deeper regularities,
 and (2) that it is quite easy to encourage children to
be interested in these regularities and to learn about
them
