Molesworth, Catherine J.; Bowler, Dermot M.; Hampton, James A. – Journal of Child Psychology and Psychiatry, 2005
Background: There are two accounts of categorization performance in autism: that there is an impairment in prototype formation (Klinger & Dawson, 2001) and that there is an impairment in processing features held in common between stimuli (Plaisted, O'Riordan, & Baron-Cohen, 1998). These accounts, together with central coherence theory (Frith,…

Denney, Colin B.; Rapport, Mark D.; Chung, Kyong-Mee – Journal of Child Psychology and Psychiatry, 2005
Background: Contemporary models of working memory suggest that target paradigm (TP) and target density (TD) should interact as influences on error rates derived from continuous performance tests (CPTs). The present study evaluated this hypothesis empirically in a typically developing, ethnically diverse sample of children. The extent to which…

Shull, Jennifer; Deitz, Jean; Billingsley, Felix; Wendel, Sue; Kartin, Deborah – Physical & Occupational Therapy in Pediatrics, 2004
Background and Purpose: The purpose of this study was to use single-subject research methods, combined with social validation procedures, as part of an evaluation/intervention process exploring the effects of adapted switch-operated devices on self-initiated behaviors of a 6-year-old child with profound multiple disabilities. Method: A…

Lidz, Jeffrey; Waxman, Sandra – Cognition, 2004
Lidz, Waxman, and Freedman [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Evidence for syntactic structure at 18-months. "Cognition," 89, B65-B73.] argue that acquisition of the syntactic and semantic properties of anaphoric one in English relies on innate knowledge within the learner.…

Di Stefano, Marirosa; Marano, Elena; Viti, Marzia – Brain and Cognition, 2004
The assessment of language laterality by the dichotic fused-words test may be impaired by interference effects revealed by the dominant report of one member of the stimuli-pair. Stimulus-dominance and ear asymmetry were evaluated in normal population (48 subjects of both sex and handedness) and in 2 patients with a single functional hemisphere.…

Bedard, Catherine; Belin, Pascal – Brain and Cognition, 2004
Voice is the carrier of speech but is also an ''auditory face'' rich in information on the speaker's identity and affective state. Three experiments explored the possibility of a ''voice inversion effect,'' by analogy to the classical ''face inversion effect,'' which could support the hypothesis of a voice-specific module. Experiment 1 consisted…

Lorusso, Maria Luisa; Facoetti, Andrea; Molteni, Massimo – Brain and Cognition, 2004
Aim of the study is to analyze the contributions of hemispheric, attentional, and processing speed factors to the effects of neuropsychological treatment of developmental dyslexia. Four groups of dyslexic children (M-type dyslexia) were treated over a period of four months. A first group (n=9) underwent Bakker's Hemisphere-Specific Stimulation,…

Balasubramanian, Venu; Max, Ludo – Brain and Cognition, 2004
The present study reports on the first case of crossed apraxia of speech (CAS) in a 69-year-old right-handed female (SE). The possibility of occurrence of apraxia of speech (AOS) following right hemisphere lesion is discussed in the context of known occurrences of ideomotor apraxias and acquired neurogenic stuttering in several cases with right…

Olk, Bettina; Wee, Joy; Kingstone, Alan – Brain and Cognition, 2004
Highly variable bisection performance in neglect patients has been attributed to an increased "zone of indifference" (Marshall & Halligan, 1989). The indifference zone indicates the discrepancy between two line lengths which are judged as equal in length. Following this argumentation, the central area of a line should be expanded in neglect…

Kim, Jeesun; Davis, Chris; Burnham, Denis; Luksaneeyanawin, Sudaporn – Brain and Language, 2004
The current research examined performance of good and poor readers of Thai on two tasks that assess sensitivity to dynamic visual displays. Readers of Thai, a complex alphabetic script that nonetheless has a regular orthography, were chosen in order to contrast patterns of performance with readers of Korean Hangul (a similarly regular language but…

Williams, Justin H. G.; Massaro, Dominic W.; Peel, Natalie J.; Bosseler, Alexis; Suddendorf, Thomas – Research in Developmental Disabilities: A Multidisciplinary Journal, 2004
Children with autistic spectrum disorder (ASD) may have poor audio-visual integration, possibly reflecting dysfunctional "mirror neuron" systems which have been hypothesised to be at the core of the condition. In the present study, a computer program, utilizing speech synthesizer software and a "virtual" head (Baldi), delivered speech stimuli for…

Huguenin, Nancy H. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2004
To effectively reduce overselective attention, a fine-grained analysis of the control exhibited by compound training cues is first needed. Computer software was developed in this study to administer two different stimulus control-testing procedures to assess how three young children of normal development and three adolescents with severe mental…

Vihman, Marilyn M.; Nakai, Satsuki; DePaolis, Rory A.; Halle, Pierre – Journal of Memory and Language, 2004
The interaction between prosodic and segmental aspects of infant representations for speech was explored using the head-turn paradigm, with untrained everyday familiar words and phrases as stimuli. At 11 months English-learning infants, like French infants (Halle & Boysson-Bardies, 1994), attended significantly longer to a list of familiar lexical…

Picture naming is a widely used technique in psycholinguistic studies. Here, we describe new on-line resources that our project has compiled and made available to researchers on the world wide web at http://crl.ucsd.edu/~aszekely/ipnp/. The website provides access to a wide range of picture stimuli and related norms in seven languages. Picture…

Little, Deborah M.; Shin, Silvia S.; Sisco, Shannon M.; Thulborn, Keith R. – Brain and Cognition, 2006
Eighteen healthy young adults underwent event-related (ER) functional magnetic resonance imaging (fMRI) of the brain while performing a visual category learning task. The specific category learning task required subjects to extract the rules that guide classification of quasi-random patterns of dots into categories. Following each classification…
