Reading development subtypes and their early characteristics.
2007
The present findings are drawn from the Jyväskylä Longitudinal Study of Dyslexia (JLD), in which approximately 100 children with familial risk of dyslexia and 100 control children have been followed from birth. In this paper we report data on the reading development of the JLD children and their classmates, a total of 1,750 children from four measurement points during the first two school years. In the total sample, we examined whether heterogeneous developmental paths can be identified based on profiles of word recognition and reading comprehension. Secondly, we studied what kind of early language and literacy skill profiles and reading experiences characterize the children with differing …
[Postural balance following stroke: towards a disadvantage of the right brain-damaged hemisphere].
1999
International audience; In the light of studies published in the last ten years, we have suspected a differential influence of the sides of hemispheric cerebral lesions on posture and balance. A study was aimed at verifying this hypothesis, the method of which being original because many possible confounding factors such as age, sex as well as topography and size of the brain lesion have been taken into account in the statistical analysis. Inclusion criteria were: right-handed patients, first stroke, no previous disease which might have affected balance. Their postural abilities (ranging from 0 to 36) were assessed 90 +/- 3 days after stroke onset on a clinical scale. This clinical assessme…
Design of a VR application for pilots as a complementary tool for procedure training of Abnormal Operations
2021
Master's thesis in Multimedia and educational technology (MM506) The aviation industry has been amongst the early adopters of VR for educational purposes, even since the very beginning of VR’s technology establishment and throughout its further development. Flight simulators are invaluable as they let pilots and instructors replicate any situation for learning full control over the plane and improve situational awareness without paying the price of life-safety if using an actual aircraft. Abnormal operations and their procedures are a key subject of safety training, where pilots have to understand and memorize particular orders of actions in order to solve a dangerous situation on board. A …
VR formidling av en kunstnerisk opplevelse : Dette prosjektet er en interaktiv kunstinstallasjon laget i VR for Sørlandets Kunstmuseum
2021
Master's thesis in Multimedia and educational technology (MM506) I denne masteroppgaven har vi laget en VR-simulering for Sørlandets Kunstmuseum i Kristiansand. Ønsket med denne formidlingen var å vekke kunstinteressen hos publikum og undersøke om dette kan være et medium som kan bidra til økt museumsbesøk. Prosjektet har tatt utgangspunkt i fire verk som er malt av den norske kunstneren Reidar Aulie. Det har blitt utført en metodetriangulering brukeranalyse med VR-simuleringen og tradisjonell kunst, som har vært med på å dra sammenligninger mellom de to ulikeformidlingene. Dette har vært med på å bekrefte eller avkrefte vår hypotese; Bruk av VR i formidling av kunst vil bidra til større in…
Investigating Motion Sickness in Racing Simulators using Virtual Reality and a Motion Platform
2021
Master's thesis in Multimedia and educational technology (MM506) Motion sickness has been a downside of virtual reality since its beginning. According to the "Sensory conflict" theory, simulation sickness and cybersickness often occurs due to the feeling of self-motion. This thesis aimed to investigate if a motion platform could mitigate simulation sickness. By using commercial available motion platform and virtual reality headset, the experiment had three conditions, one without any added motion, one with motion and the last with increased motion. Participants were put in a complete racing set to drive an Edge 6D motion simulator in Asseto Corsa. The participants drove a high-speed car for…
Real-time video transmission in UMTS
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad Universal Mobile Telecommunication System is denoted as a 3rd cellular system and has been designed with the objective to be a system with global coverage. With the major improvement of in bandwidth capability the Universal Mobile Telecommunications System will be able to support real time multimedia services. This thesis starts with a presentation of the possible video services that can be exploited in third generation cellular systems. Video services are known to be bandwidth consuming and have rigid requirements to the real time requirements. Though the major increase in available bandwidth in the…
Qualitative differences in the exploration of upright and upside-down faces in four-month-old infants : An eye-movement study
2006
The goal of this study was to test if apprentice readers (6-7 to 7-8 years old) and beginner readers (8-9 to 10-11 years old) perceive syllabic units in written words. The paradigm of illusory conjunctions was used because it can determine the infra-lexical units identified at the first steps of the written stimuli process. Two experiments were conducted on children from the first (6-7 years old) to the last years (10-11 years old) of the learning-to-read process. Results have shown that children perceive syllables in letter sequences as soon as the end of the first year of the learning-to-read process. The perception of these units is the result of two information sources: the syllabic pho…
Influence of reading skill and word length on fixation-related brain activity in school-aged children during natural reading
2019
Word length is one of the main determinants of eye movements during reading and has been shown to influence slow readers more strongly than typical readers. The influence of word length on reading in individuals with different reading skill levels has been shown in separate eye-tracking and electroencephalography studies. However, the influence of reading difficulty on cortical correlates of word length effect during natural reading is unknown. To investigate how reading skill is related to brain activity during natural reading, we performed an exploratory analysis on our data set from a previous study, where slow reading (N = 27) and typically reading (N = 65) 12-to-13.5-year-old children …
Age-related differences in a delayed pointing of a M�ller-Lyer illusion
2003
It has been suggested that movements to visible or remembered targets are differently sensitive to the Müller-Lyer (ML) illusion. Indeed, when the target is continuously visible, movements rely on the veridical object characteristics, whereas remembered movements are thought to reflect the perceived characteristics of the object. The aim of the present study was to determine how movements to visible or remembered targets are influenced by the ML illusion in children aged 7 to 11 years old. Participants were asked to make a perceptual judgment or to point a shaft extremity of the ML configurations (Closed, Control, and Open) in three visual conditions (Closed Loop, Open Loop-0-s delay, and 5…
Error Detection and Response Adjustment in Youth With Mild Spastic Cerebral Palsy
2013
This study evaluated the brain activation state during error making in youth with mild spastic cerebral palsy and a peer control group while carrying out a stimulus recognition task. The key question was whether patients were detecting their own errors and subsequently improving their performance in a future trial. Findings indicated that error responses of the group with cerebral palsy were associated with weak motor preparation, as indexed by the amplitude of the late contingent negative variation. However, patients were detecting their errors as indexed by the amplitude of the response-locked negativity and thus improved their performance in a future trial. Findings suggest that the con…
