Early emergence of deviant frontal fMRI activity for phonological processes in poor beginning readers.
2010
Phonological awareness refers to the ability to perceive and manipulate the sound structure of language and is especially important when children learn to read. Poor phonological awareness is considered the major cause for the emergence of reading difficulties. In this functional magnetic resonance imaging (fMRI) study, we examined the brain correlates of phonological processing in young beginning readers (aged 8.3+/-0.4 y, 2nd grade) with poor (25th percentile) or normal, age-appropriate reading skills (40th percentile) using a covert reading and mental letter substitution task. Letter substitution in words and nonwords induced pronounced activity in a left frontal language network related…
Assessment of Three-and-a-Half-Year-Old Children's Emerging Phonological Awareness in a Computer Animation Context
2003
Four computer-animated tasks were created to analyze the underlying structure of emerging phonological awareness at 3.5 years of age and to explore the factors that influence children's ( N = 91) performance on the tasks. Our findings indicated that already at this young age, children are able to master tasks demanding identification, blending, and continuation of phonological units when the tasks are presented in a motivating assessment context. In line with earlier research, children showed higher mastery in dealing with words and syllables than in dealing with phonemes. Targets in the initial position of a word were easier for children to identify than those in the final position. Our an…
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…

Study protocol for an online questionnaire survey on symptoms/signs, protective measures, level of awareness and perception regarding covid-19 outbre…
2020
The Centres for Disease Control and Prevention and the World Health Organization have developed preparedness and prevention checklists for healthcare professionals regarding the containment of COVID-19. The aim of the present protocol is to evaluate the impact of the COVID-19 outbreak among dentists in different countries where various prevalence of the epidemic has been reported. Several research groups around the world were contacted by the central management team. The online anonymous survey will be conducted on a convenience sample of dentists working both in national health systems and in private or public clinics. In each country/area, a high (~5–20%) proportion of dentists working th…
Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness
2017
International audience; Recent studies have highlighted the role of multisensory integration as a key mechanism of self-consciousness. In particular, integration of bodily signals within the peripersonal space (PPS) underlies the experience of the self in a body we own (self-identification) and that is experienced as occupying a specific location in space (self-location), two main components of bodily self-consciousness (BSC). Experiments investigating the effects of multisensory integration on BSC have typically employed supra-threshold sensory stimuli, neglecting the role of unconscious sensory signals in BSC, as tested in other consciousness research. Here, we used psychophysical techniq…
Precursors and consequences of phonemic length discrimination ability problems in children with reading disabilities and familial risk for dyslexia.
2013
Purpose The authors investigated the importance of phonemic length discrimination ability on reading and spelling skills among children with reading disabilities and familial risk for dyslexia and among children with typical reading skills, as well as the role of prereading skills in reading and spelling development in children with reading disabilities. Method Finnish children with reading disabilities and discrimination problems (RDDP, n = 13), children with reading disabilities and typical discrimination abilities (RDTD, n = 27), and children with typical reading skills (TR, n = 140) were assessed between the ages of 1 and 6.5 years for language, phonological awareness, IQ, verbal memor…
Is a specialised training of phonological awareness indicated in every preschool child?
2008
<i>Objective and Methods: </i>In a prospective study 218 preschool children were enrolled (stratified in 2 training programs, one specialized for phonologic awareness in order to prevent dyslexia, the other consisting in training of general perception) during the last year of kindergarten. After finishing the first grade 131 children were compared in their reading and writing abilities.<i> Results: </i>In the whole group only a slight difference was found between both training modalities concerning their writing abilities. However, children with a history of hearing loss, actual hearing loss or pathologic middle ear findings profited most from the specialized trainin…
Pattern analyses reveal separate experience-based fear memories in the human right Amygdala
2017
Learning fear via the experience of contingencies between a conditioned stimulus (CS) and an aversive unconditioned stimulus (US) is often assumed to be fundamentally different from learning fear via instructions. An open question is whether fear-related brain areas respond differently to experienced CS–US contingencies than to merely instructed CS–US contingencies. Here, we contrasted two experimental conditions where subjects were instructed to expect the same CS–US contingencies while only one condition was characterized by prior experience with the CS–US contingency. Using multivoxel pattern analysis of fMRI data, we found CS-related neural activation patterns in the right amygdala (but…
What users think about the differences between caffeine and illicit/prescription stimulants for cognitive enhancement
2012
Pharmacological cognitive enhancement (CE) is a topic of increasing public awareness. In the scientific literature on student use of CE as a study aid for academic performance enhancement, there are high prevalence rates regarding the use of caffeinated substances (coffee, caffeinated drinks, caffeine tablets) but remarkably lower prevalence rates regarding the use of illicit/prescription stimulants such as amphetamines or methylphenidate. While the literature considers the reasons and mechanisms for these different prevalence rates from a theoretical standpoint, it lacks empirical data to account for healthy students who use both, caffeine and illicit/prescription stimulants, exclusively f…
