Newborn event-related potentials predict poorer pre-reading skills in children at risk for dyslexia.
2009
Earlier results from the Jyväskylä Longitudinal Study of Dyslexia showed that newborn event-related potentials (ERPs) of children with and without familial risk for dyslexia were associated with receptive language and verbal memory skills between 2.5 and 5 years of age. We further examined whether these ERPs (responses to synthetic consonant-vowel syllables /ba/, /da/, /ga/; presented equiprobably with 3,910—7,285 ms interstimulus intervals) predict later pre-reading skills measured before the onset of school (6.5 years of age). In line with our earlier results, the at-risk children ( N = 11) with atypical speech processing in the right hemisphere (a slower shift in polarity from positivit…
Mothers' Causal Attributions Concerning the Reading Achievement of Their Children With and Without Familial Risk for Dyslexia
2008
The present study analyzed data from the Jyväskylä Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school year. Children's verbal intelligence was assessed at 5 years and their word and nonword reading skills at 6.5 years. The results showed that the higher the word reading skills the children had, the more their mothers attributed their success to ability than to effort. However, if children had familial risk for dyslexia, their mothers' attribution o…
Understanding developmental language disorder-The Helsinki longitudinal SLI study (HelSLI): A study protocol
2018
Background Developmental language disorder (DLD, also called specific language impairment, SLI) is a common developmental disorder comprising the largest disability group in pre-school-aged children. Approximately 7% of the population is expected to have developmental language difficulties. However, the specific etiological factors leading to DLD are not yet known and even the typical linguistic features appear to vary by language. We present here a project that investigates DLD at multiple levels of analysis and aims to make the reliable prediction and early identification of the difficulties possible. Following the multiple deficit model of developmental disorders, we investigate the DLD …
Orthodontic treatment stability predictors: A retrospective longitudinal study
2016
ABSTRACTObjective: To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables.Materials and Methods: In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range.Results: Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- …
Long-term analysis of upper incisor crowding. A longitudinal study orthodontically treated patients
2010
Introduction: Although there are numerous studies in the literature on alignment stability in the lower arch, there are few referring to the upper arch. Aims: To assess upper arch stability (irregularity index, widths and length of arch, overjet and overbite) in orthodontically treated patients by comparing late incisor stability with the initial malocclusion and type pf treatment undertaken. Study design: The study models of 51 patients, treated with or without extractions, were analysed at three different points in time: pre-treatment (T1), post-treatment (T2) and post-retention (T3) (average 5 years). The following parameters were measured: irregularity index, arch length, inter-canine a…
The role of learning to read in the development of problem behaviour: A cross-lagged longitudinal study
2006
Background. This study investigates the posited relationship between learning to read, and internalizing and externalizing problem behaviours, during the transition from preschool to primary school. Methods. A total of 196 (104 boys, 92 girls) children participating in the Jyvaskyla Entrance into Primary School (JEPS) study were followed up six times during their transition from preschool to primary school. At each measurement, the children's reading performance was tested. Moreover, their internalizing and externalizing problem behaviour was examined by means of structured interviews. Results. The results showed that problems in reading acquisition predicted an increase in internalizing pr…
A long-term evaluation of treated Class II division 2 malocclusions: a retrospective study model analysis
1999
Pre-treatment, end of treatment, and post-retention study models of 30 subjects with a Class II division 2 malocclusion were assessed, after a period of at least 3 years, in order to evaluate the long-term changes in occlusion, alignment, and arch dimensions. Molar relationship correction was found to be stable after retention. There were no variables which could be used to establish a prognosis of vertical stability. Over-correction of overbite was seen to relapse. Ten per cent of the cases showed unacceptable anterior maxillary irregularities after retention. Mandibular arch width and length usually showed a decrease after retention. An increase in lower intercanine width and arch length …
The role of letter features in visual-word recognition: Evidence from a delayed segment technique.
2016
Available online 9 June 2016 Do all visual features in aword's constituent letters have the same importance during lexical access? Herewe examined whether some components of a word's letters (midsegments, junctions, terminals) are more important than others. To that end,we conducted two lexical decision experiments using a delayed segment techniquewith lowercase stimuli. In this technique a partial previewappears for 50ms and is immediately followed by the target item. In Experiment 1, the partial preview was composed of terminals+junctions,midsegments+junctions, or midsegments + terminals — a whole preview condition was used as a control. Results only revealed an advantage of the whole pre…
Do mental processes share a domain-general resource?
2010
What determines success and failure in dual-task situations? Many theories propose that the extent to which two activities can be performed concurrently depends on the nature of the information involved in the activities. In particular, verbal and visuospatial activities are thought to be fueled by distinct resources, so that interference occurs between two verbal activities or two visuospatial activities, but little or no interference occurs between verbal and visuospatial activities. The current study examined trade-offs in four dual-task situations in which participants maintained verbal or visuospatial information while concurrently processing either verbal or visuospatial information.…
Maintenance of item and order information in verbal working memory
2017
International audience; Although verbal recall of item and order information is well-researched in short-term memory paradigms, there is relatively little research concerning item and order recall from working memory. The following study examined whether manipulating the opportunity for attentional refreshing and articulatory rehearsal in a complex span task differently affected the recall of item- and order-specific information of the memoranda. Five experiments varied the opportunity for articulatory rehearsal and attentional refreshing in a complex span task, but the type of recall was manipulated between experiments (item and order, order only, and item only recall). The results showed …
