Chewing gum differentially affects aspects of attention in healthy subjectsOliver Tucha
Institute of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany

Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Brain Res 1090:146-55. 2006..This result suggests that brain activation in the present study illustrates the brain regions involved in the basic cognitive mechanisms of response shifting... - The effect of caffeine on handwriting movements in skilled writersOliver Tucha
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Hum Mov Sci 25:523-35. 2006..The results suggest that higher doses of caffeine can enhance psychomotor performance... - Limitations of the dual-process-theory regarding the writing of words and non-words to dictationOliver Tucha
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany

Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Appetite 43:219-20; discussion 221-3. 2004..Future studies are needed to assess various aspects of cognitive functioning using extensive standardised neuropsychological test batteries, adequate experimental designs and appropriate statistical methods... - Brain dopamine and kinematics of graphomotor functionsKlaus W Lange
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Hum Mov Sci 25:492-509. 2006..Central dopamine appears to be of particular importance with regard to the automatic execution of well-learned movements... - The effect of conscious control on handwriting in children with attention deficit hyperactivity disorderOliver Tucha
University of Regensburg, Germany
J Atten Disord 9:323-32. 2005..The results suggest that both visual and mental control of handwriting movements affect the automation of handwriting movements. Furthermore, a simple training procedure was designed and performed in a case study of a boy with ADHD... - Effects of nicotine chewing gum on a real-life motor task: a kinematic analysis of handwriting movements in smokers and non-smokersOliver Tucha
Institute of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Psychopharmacology (Berl) 173:49-56. 2004..No effects of nicotine were found with regard to the quality of handwriting. CONCLUSION: The results suggest that nicotine can enhance psychomotor performance to a significant degree in a real-life motor task... - Attention and movement execution during handwritingOliver Tucha
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Hum Mov Sci 25:536-52. 2006..The quality of handwriting was not affected by TSD. These findings may suggest an independence between attention and movement generation during handwriting... - Effects of methylphenidate on multiple components of attention in children with attention deficit hyperactivity disorderOliver Tucha
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Psychopharmacology (Berl) 185:315-26. 2006..Although MPH-induced improvements were observed in a broad range of attention measures, children with ADHD who were on MPH treatment nevertheless displayed serious deficits in a number of components of attention... 
The effects of the neurotoxin DSP4 on spatial learning and memory in Wistar ratsJoachim Hauser
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Atten Defic Hyperact Disord 4:93-9. 2012..Future studies will therefore have to take into account the time-course of neurotransmitter alterations and behavioural changes following DSP4 administration...- Effects of DSP4 and methylphenidate on spatial memory performance in ratsThomas A Sontag
Department of Experimental Psychology, University of Regensburg, 93040, Regensburg, Germany
Atten Defic Hyperact Disord 3:351-8. 2011..It is suggested that a reduction of noradrenaline and an increase of dopamine induce ADHD-related deficits and that the depletion of noradrenaline is not sufficient for an appropriate rat model of ADHD... - Executive functions in children with dyslexiaAstrid Reiter
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Dyslexia 11:116-31. 2005..The present findings suggest that children with dyslexia demonstrate impairments in a variety of executive functions. This should be considered in the development of new concepts in the treatment of dyslexia... - The history of attention deficit hyperactivity disorderKlaus W Lange
Department of Biological and Abnormal Psychology, University of Regensburg, Germany
Atten Defic Hyperact Disord 2:241-55. 2010..This article presents an overview of the conceptual history of modern-day ADHD... - Circadian rhythms in obsessive-compulsive disorderKlaus W Lange
Department of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
J Neural Transm 119:1077-83. 2012..Adjunctive chronotherapy might also enhance the outcome in treatment-refractory OCD. The present review summarises the findings regarding circadian abnormalities in OCD... - Handwriting and attention in children and adults with attention deficit hyperactivity disorderOliver Tucha
Dept of Experimental Psychology, University of Regensburg, 93040 Regensburg, Germany
Motor Control 8:461-71. 2004..Both children and adults with ADHD could perform age-appropriate and automated handwriting movements. Children with ADHD on medication, however, gave more attention to the writing process, possibly hampering fluent handwriting movements...
