Coach autonomy support and quality of sport engagement in young soccer players.
2009
Based on the self-determination theory (Ryan & Deci, 2000), this study tested a model of the assumed sequential relationships between perceived autonomy support, psychological need satisfaction, self-determined motivation, and enjoyment/boredom. The hypothesized mediational roles of psychological need satisfaction and self-determined motivation were also studied. In a sample of 370 young male soccer players, path analysis results offered support for the proposed model. Total mediation was supported in the case of the psychological need satisfaction in the relationship between autonomy support and self-determined motivation, and partial mediation for self-determined motivation in the lin…
Children with differing developmental trajectories of prelinguistic communication skills: language and working memory at age 5.
2014
Purpose In this article, the authors examine the developmental continuity from prelinguistic communication to kindergarten age in language and working memory capacity. Method Following work outlining 6 groups of children with different trajectories of early communication development (ECD; Määttä, Laakso, Tolvanen, Ahonen, & Aro, 2012), the authors examined their later development by psychometric assessment. Ninety-one children first assessed at ages 12–21 months completed a battery of language and working memory tests at age 5;3 (years;months). Results Two of the ECD groups previously identified as being at risk for language difficulties continued to show weaker performance at follow-u…
The SF-8 Spanish Version for Health-Related Quality of Life Assessment: Psychometric Study with IRT and CFA Models.
2018
AbstractThe aim of current research is to analyze the psychometric properties of the Spanish version of the SF–8, overcoming previous shortcomings. A double line of analyses was used: competitivestructural equations modelsto establish factorial validity, andItem Response theoryto analyze item psychometric characteristics and information. 593 people aged 60 years or older, attending long life learning programs at the University were surveyed. Their age ranged from 60 to 92 years old. 67.6% were women. The survey included scales on personality dimensions, attitudes, perceptions, and behaviors related to aging. Competitive confirmatory models pointed out two-factors (physical and mental health…
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…
The Selective Impairment of Phonological Processing in Speech Production
2000
We report the naming performance of a patient (DM) with a fluent progressive aphasia who made phonological errors in all language production tasks. The pattern of errors in naming was strikingly clear: DM made very many phonological errors that resulted almost always in nonword responses. The complete absence of semantic errors and the very low ratio of formal errors relative to nonword errors (1.6:30.3) in DM's performance are discussed in the context of recent claims about the nature of naming deficits in fluent aphasics. We argue that DM's performance makes highly improbable the claim that fluent aphasia results from global lesions affecting all levels of the lexical access system equall…
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…
Centre-embedded structures are a by-product of associative learning and working memory constraints: Evidence from baboons (Papio Papio)
2012
International audience; Influential theories have claimed that the ability for recursion forms the computational core of human language faculty distinguishing our communication system from that of other animals (Hauser, Chomsky, & Fitch, 2002). In the present study, we consider an alternative view on recursion by studying the contribution of associative and working memory processes. After an intensive paired-associate training with visual shapes, we observed that baboons spontaneously ordered their responses in keeping with a recursive, centre-embedded structure. This result suggests that the human ability for recursion might partly if not entirely originate from fundamental processing cons…
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…
Partial replication of a DRD4 association in ADHD individuals using a statistically derived quantitative trait for ADHD in a family-based association…
2007
Contains fulltext : 52515.pdf (Publisher’s version ) (Closed access) BACKGROUND: Previous research found an association between single nucleotide polymorphisms (SNPs) in the promoter region of DRD4 and statistically derived phenotypes generated from attention-deficit/hyperactivity disorder (ADHD) symptoms. We sought to replicate this finding by using the same methodology in an independent sample of ADHD individuals. METHODS: Four SNPs were genotyped in and around DRD4 in 2631 individuals in 642 families. We developed a quantitative phenotype at each SNP by weighting nine inattentive and nine hyperactive-impulsive symptoms. The weights were selected to maximize the heritability at each SNP. …
