Cappelletti, Marinella; Freeman, Elliot D.; Cipolotti, Lisa – Neuropsychologia, 2009
This study investigated time, numerosity and space processing in a patient (CB) with a right hemisphere lesion. We tested whether these magnitude dimensions share a common magnitude system or whether they are processed by dimension-specific magnitude systems. Five experimental tasks were used: Tasks 1-3 assessed time and numerosity independently…

Carroll, Christine A.; O'Donnell, Brian F.; Shekhar, Anantha; Hetrick, William P. – Brain and Cognition, 2009
Schizophrenia may be associated with a fundamental disturbance in the temporal coordination of information processing in the brain, leading to classic symptoms of schizophrenia such as thought disorder and disorganized and contextually inappropriate behavior. Although a variety of behavioral studies have provided strong evidence for perceptual…

Hwang, Shoou-Lian; Gau, Susan Shur-Fen; Hsu, Wen-Yau; Wu, Yu-Yu – Journal of Child Psychology and Psychiatry, 2010
Background: The underlying mechanism of time perception deficit in long time intervals in attention-deficit/hyperactivity disorder (ADHD) is still unclear. This study used the time reproduction dual task to explore the role of the attentional resource in time perception deficits among children and adolescents with ADHD. Methods: Participants…

Lum, Jarrad A. G.; Conti-Ramsden, Gina; Lindell, Annukka K. – Brain and Cognition, 2007
Rapid processing deficits have been the subject of much debate in the literature on specific language impairment (SLI). Hari and Renvall (2001) [Hari, R. & Renvall, H. (2001). Impaired processing of rapid stimulus sequences in dyslexia. "Trends in cognitive sciences", 5, 525-532.] proposed that the source of this deficit can be attributed to…

Solanto, Mary V.; Gilbert, Sharone N.; Raj, Anu; Zhu, John; Pope-Boyd, Sa'brina; Stepak, Brenda; Vail, Lucia; Newcorn, Jeffrey H. – Journal of Abnormal Child Psychology, 2007
The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal…

Frings, Markus; Boenisch, Raoul; Gerwig, Marcus; Diener, Hans-Christoph; Timmann, Dagmar – Learning & Memory, 2004
A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…
