A Retrospective Longitudinal Study of Cognitive and Language Skills in Poor Reading Comprehension
- 2014
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Fifty-six specific poor reading comprehenders (SPRC) were selected in grade 4 and retrospectively compared to good comprehenders at preschool age 5 and at the end of kindergarten, grade 1 and 2. The results showed a widespread language-deficit profile in children with SPRC, including deficits in vocabulary, grammar, verbal memory and early phonological awareness in a large part of the sample beginning in preschool. The reading comprehension deficits in children with SPRC were not as apparent in earlier assessments at grade 1 and 2, likely because of the greater dependence on word decoding in reading comprehension in the early grades.

- Fifty-six specific poor reading comprehenders (SPRC) were selected in Grade 4 and retrospectively compared to good comprehenders at preschool (age 5) and at the end of kindergarten, Grade 1, and Grade 2. The results revealed deficits in vocabulary, grammar, verbal memory and early deficits in phonological awareness in most of the SPRC sample, beginning in preschool. The reading comprehension deficits in children with SPRC were not as marked in earlier assessments in Grade 1 and 2, probably because of the greater dependence on word decoding in reading comprehension in the early grades.

Early Predictors of Reading Comprehension Difficulties
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the present thesis was to examine the cognitive and language profile in children with poor reading comprehension using a longitudinal perspective. Even though comprehension skills are closely connected to educational success, comprehension deficits in children have been neglected in reading research. Understanding factors underlying reading is important as it improves possibilities of early identification of children at risk of developing reading problems. In addition, targeted interventions may prevent or reduce future problems. Descriptions of the cognitive and language profile in children with different types of reading problems from an early age and over time is an important first step.The three studies included in this thesis have been conducted using data from the International Longitudinal Twin Study (ILTS). In the ILTS, parallel data have been collected in the US, Australia, Sweden and Norway. Altogether, more than 1000 twin pairs have been examined between the ages 5 and 15 years using well known predictors of reading, along with decoding, spelling, reading comprehension and oral language measures.In the three studies, the Simple View of Reading has been used as a theoretical framework and children who exhibited different kinds of comprehension related difficulties have been identified at different ages. The studies include both retrospective and prospective analyses. The results across studies indicated a robust oral language deficit in all subtypes displaying comprehension problems. The oral language deficit was widespread and included vocabulary, grammar and verbal memory. In addition, the oral language deficit was manifested as compromised phonological awareness and print knowledge prior to reading instruction. Reading comprehension deficits were late emerging across studies in children with comprehension difficulties.

Pattern of Preschool Prediction of Reading Comprehension Impairment : A 10 Year Longitudinal Study
- 2014
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Compromised reading comprehension will invariably influence future academic achievements. In reading research there has been an emphasis on early identification of poor decoders to reduce future difficulties. Only a few studies have examined preschool prediction of reading comprehension impairments beyond the first grades of school, and these studies have presented different patterns of results. As studies have mostly been conducted in English; it is unclear how the results generalize to languages with transparent orthographies. In this study, a Swedish and a Norwegian twin sample were used to predict reading comprehension and decoding impairments in grade 2, 4 and 8/9 from preschool. The results suggested an important role for RAN and verbal memory. Compromised RAN was consistently associated with the poor decoders, as well as in identifying poor reading comprehenders in grade 8/9. Verbal memory tasks at preschool contributed to the identification of children with reading comprehension impairment across grades.

Intelligence and dyslexia : Implications for diagnosis and intervention

Tidskriftsartikel (refereegranskat)abstract
- In this paper we critically examine theoretical issues and practical consequences of including IQ in the definition of dyslexia. According to the discrepancy criterion individuals are classified as dyslexic if their reading skills are below what would be expected from their IQ scores. However, we argue that intelligence is a fuzzy concept and that there is no clear causal relationship between intelligence level and word decoding skills. Also, high and low IQ poor readers show the same reading performance patterns, indicating that both groups might benefit from the same remedial activities. Evidence for the critical role of phonological skills in dyslexia is presented and a more recent definition of dyslexia is discussed in relation to these findings. Finally, two alternative, more outcome-based classifications of poor readers are suggested and some critical consequences for individual interventions are outlined.

Varieties of reading disability : Phonological and orthographic word decoding deficits and implications for interventions
- 2000
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The general aim of this thesis was to examine variations in the word decoding skills of reading disabled children. These variations were related to possible cognitive, developmental, and environmental causes of reading disability. Possible implications for educational interventions were also analysed. The thesis critically examines the inclusion of the concept of intelligence in the definition of developmental dyslexia. It is suggested that variations in word decoding skills should offer a more solid basis for a study of varieties of reading disability. The empirical studies showed that a) in young children there was a shift from phonological to orthographic word decoding; b) phonological type children (weak in phonological decoding) were characterised by specific phonological deficits; c) surface type children (weak in orthographic decoding) showed more global cognitive deficits suggesting a general developmental delay; d) surface type children showed impaired visual implicit memory for words, which might be associated with limited print exposure; e) an improvement in phonological awareness only transferred to an improved text reading ability for some reading disabled children; f) children who did not benefit from a phonological intervention seemed to rely on orthographic word decoding in text reading. Thus, the thesis suggests that variations in phonological and orthographic word decoding skills offer a useful basis for the study of varieties of reading disability and that educational interventions should pay regard to what the child is already attempting to do when reading.
