Representational Bias in the Radial Axis in Children With Dyslexia: A Landmarks Alignment Study.

2018

To better identify the distinctive characteristics of space representation in the radial dimension, we have proposed a new paradigm: the landmarks alignment task where two parallel aluminum bars were radially presented. Children had to move a landmark along one bar and place it at the same location as the reference landmark placed by the examiner on the parallel bar. The major interest of this task was its capacity to assess space representation in the radial dimension when considering a spatial landmark that oriented the subject’s attention toward the orthogonal dimension. The most important result showed that in the radial dimension children with dyslexia exhibited a forward bias on the …

Predicting Delay in Reading Achievement in a Highly Transparent Language

2004

A random sample of 91 preschool children was assessed prior to receiving formal reading instruction. Verbal and nonverbal measures were used as predictors for the time of instruction required to accurately decode pseudowords in the highly orthographically regular Finnish language. After 2 years, participants were divided into four groups depending on the duration of instruction they had required to reach 90 % accuracy in their reading of pseudowords. Participants were classified as precocious decoders (PD), who could read at school entry; early decoders (ED), who learned to read within the first 4 months of Grade 1; ordinary decoders (OD), who learned to read within 9 months; and late deco…

Is attribution retraining necessary? Use of self-regulation procedures for enhancing the reading comprehension strategies of children with learning d…

1997

The present study investigates the need to include explicit attribution retraining in a program designed to teach reading comprehension strategies to children with learning disabilities (LD). The program had two versions: (a) self-regulation procedures and (b) self-regulation procedures plus explicit attributional retraining. Sixty children with LD were assigned to two training groups (with and without attributional retraining) and a control group. Twenty normally achieving students served as an additional control group. The effects were assessed via attribution measures and cognitive and metacognitive reading comprehension tests. Results indicated that children from both training groups i…

Neuroprotective effect of ceftriaxone on the penumbra in a rat venous ischemia model.

2012

Glutamate transporter-1 (GLT-1) maintains low concentrations of extracellular glutamate by removing glutamate from the extracellular space. It is controversial, however, whether upregulation of GLT-1 is neuroprotective under all ischemic/hypoxic conditions. Recently, a neuroprotective effect of preconditioning with a β-lactam antibiotic ceftriaxone (CTX) that increases expression of GLT-1 has been reported in animal models of focal ischemia. On the other hand, it is said that CTX does not play a neuroprotective role in an in vitro study. Thus, we examined the effect of CTX on ischemic injury in a rat model of two-vein occlusion (2VO). This model mimics venous ischemia during, e.g. tumor sur…

Fluency and rule breaking behaviour in the frontal cortex

2020

Design (DF) and phonemic fluency tests (FAS; D-KEFS, 2001) are commonly used to investigate voluntary generation. Despite this, several important issues remain poorly investigated. In a sizeable sample of patients with focal left or right frontal lesion we established that voluntary generation performance cannot be accounted for by fluid intelligence. For DF we found patients performed significantly worse than healthy controls (HC) only on the switch condition. However, no significant difference between left and right frontal patients was found. In contrast, left frontal patients were significantly impaired when compared with HC and right frontal patients on FAS. These lateralization findin…

ERP correlates of letter identity and letter position are modulated by lexical frequency

2013

The encoding of letter position is a key aspect in all recently proposed models of visual-word recognition. We analyzed the impact of lexical frequency on letter position assignment by examining the temporal dynamics of lexical activation induced by pseudowords extracted from words of different frequencies. For each word (e.g., BRIDGE), we created two pseudowords: A transposed-letter (TL: BRIGDE) and a replaced-letter pseudoword (RL: BRITGE). ERPs were recorded while participants read words and pseudowords in two tasks: Semantic categorization (Experiment 1) and lexical decision (Experiment 2). For high-frequency stimuli, similar ERPs were obtained for words and TL-pseudowords, but the N400…

Self-Generated Explanations on the Question Demands are not Always Helpful

2013

AbstractThis study had two main purposes. First, to measure high-school students’ task model representation under the instruction to self-explain questions; second, to test the effects of self-generated explanations on task-demands understanding and performance on questions. We designed a simple experimental situation where high-school students were asked to read two texts and answer questions. Only in half of the questions students were required to self-explain with their own words what the question was asking them for before answering. Contrary to our expectations, self-explaining the questions did not significantly affect skilled comprehenders, whereas it hindered performance in less-ski…

Strategic Decisions in Task-Oriented Reading.

2015

AbstractAnswering questions from texts are assessment and instructional activities that are frequently used in schools. Nevertheless, little is known about the strategic processes that students take while performing these tasks. We explored the amount and frequency that students initially read of a text before they answered questions pertaining to the material. In a procedure similar to the one used in the PISA (Program for International Students Assessment), one-hundred-seventy students between 7thand 9thgrade read and answered several questions designed to assess task-oriented reading in three specific texts. We recorded on-line indexes that evaluated student behavior (e.g., the amount of…

Perception of phonemic length and its relation to reading and spelling skills in children with family risk for dyslexia in the first three grades of …

2010

Purpose To examine the ability to discriminate phonemic length and the association of this ability with reading accuracy, reading speed, and spelling accuracy in Finnish children throughout Grades 1–3. Method Reading-disabled (RDFR, n = 35) and typically reading children (TRFR, n = 69) with family risk for dyslexia and typically reading control children (TRC, n = 80) were tested once in each grade of Grades 1–3 using a phonemic length discrimination task. Reading, spelling, IQ, verbal short-term memory, phonological memory, and naming speed were assessed. Results The RDFR group made more errors in phonemic length discrimination than the TRC group in Grades 2 and 3. After taking into accoun…
