Article
In this study, we aimed to determine whether a new measure of fine motor skills, the Pen Stroke Test (PST), can discriminate between children with and without attention-deficit/hyperactivity disorder (ADHD). Twelve children with ADHD and 12 controls age 8–11 were asked to produce handwriting strokes on a digitizer. The sigma-lognormal model derived...

Neurocognitive functioning in Tourette syndrome (TS) has been the subject of intensive research in the past 30 years. A variety of impairments, presumably related to frontal and frontostriatal dysfunctions, have been observed. These impairments were found in various domains, such as attention, memory, executive functions, language, motor and visuom...

Article
The neuropsychology of attention deficit/hyperactivity disorder (ADHD) has been extensively studied, with a general focus on global performance measures of executive function. In this study, we compared how global (i.e., endpoint) versus process (i.e., dynamic) measures of performance may help characterize children with and without ADHD using a des...

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder. Inattention, hyperactivity, and impulsivity are key symptoms of ADHD. It is typically associated with working memory deficits at the cognitive level. For this reason, interventions have been designed to train working memory in ADHD. Currently,...
Article
Infant-directed speech (IDS) is believed to facilitate language learning. However, the benefit may be either due to clearer acoustic correlates to linguistic structures, or simply increased attention from infants induced by IDS exaggerated prosody. This study investigated the pure effect of IDS pitch on lexical tone learning, with attentional/affec...
Article
Full-text available
This study uses connectionist modeling to explore whether and how infants might learn prosodic focus directly from continuous speech input. Focus is a communicative function that serves to put emphasis on a particular part of an utterance, and it is mainly encoded by pitch variations. The acquisition of focus entails two major difficulties. The fir...
Article
Infants develop phonetic categories by simply being exposed to adult speech. It remains unclear, however, how they handle the extensive variability inherent to speech, and how they process multiple linguistic functions that share the same acoustic parameters. Across four neural network simulations of lexical tone acquisition, self-organizing maps w...
Article
We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; ) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F(0) contours, produced by multiple speakers in...
Article
The surface F0 patterns of lexical tones contain variability from many different sources, which raises questions as to how infants can learn tones based on such highly variable input. A recent modeling study showed that the velocity profiles of F0 (i.e., first derivatives, or D1) enable naive learners to successfully categorize the four Mandarin to...
Article
Previous work showed that 8‐month‐old French‐learning infants segment both highly and moderately frequent function words from continuous speech [Shi and Gauthier, J. Acoust. Soc. Am. 117, 2426 (2005)]. In the present study we examine if high‐frequency function words are segmented by even younger infants. Participants were 6‐month‐old Quebec‐French‐...
Article
Functional elements are crucial for the structure of the grammar. Both innatist and inductionist frameworks of language acquisition pay particular attention to the development of these elements. Classic work showed that function words and functional morphemes start to emerge in children's speech much later than content words; children's early produ...
Article
Perception studies have shown that by the age of six months, infants show particular response patterns to tones in their native language. The present study focuses on how infants might develop lexical tones in Man‐ darin. F0 is generally considered the main cue in tone perception. However, F0 patterns in connected speech display extensive contextua...
Article
Previous work has shown that German-learning 7-9-month-old infants recognize function words (Hoehle and Weissenborn, 2003). English-learning infants recognize function words around 10.5-11 months (Schafer et al. 1998; Shady, 1996; Shi et al., 2003, 2004), and the highly frequent determiner ``the'' at 8 months (Shi et al., 2004). The present study i...

Full-text available
Previous research has shown that the perception of speech in infants moves gradually from being language-general to be ing language-specific during the first year of life. Recently, it was found that infants learning a tone language begin to show particular response patterns to tones in their native language during their first year [1]. In this stu...
Article
The habituation techniques used in infant speech perception studies are based on the fact that infants show renewed interest towards novel stimuli. Recent work has shown the possibility of using artificial neural networks to model habituation and dishabituation (e.g., Schafer and Mareschal, 2001). In our study we examine weather the self-organizing...
