y functional anomalies of proprioception involving postural instabilities. A recent study has
shown a PDS in all 45 children included suffering from developmental reading disabilities. This
leads to the question of the relationships between the two syndromes. In the present study, 50
dyslexic children were carefully assessed with neuropsychological batteries and examined from
clinical standards used to diagnose the PDS. They also were examined with an accurate protocol
using a force platform. The link between PDS and dyslexia is discussed in the light of cognitive
deficits of reading.
2028.126 Development of a cross-cultural neurocognitive screening test, Ihan Lam, Robert
Anderson, Argosy University/Honolulu, USA
A cross-cultural neurocognitive screening test consisting of 13 subtests has been designed to
capture many of the areas of cognitive functioning. It has the following advantages. First, It
requires less time and resources than a comprehensive neuropsychological assessment. Screening
items are used for a rapid and efficient administration (approximately 30 minutes). Moreover, it is
designed for cross-cultural applicability. Feedback from a panel of experts on cross-cultural
clinical psychology was used to ensure its translatability across cultures. Finally, the test is
available for free, particularly beneficial to qualified clinicians in developing countries.
Preliminary research suggests that it has adequate reliability.

Corticobasal Ganglionic Degeneration (CBGD) is a progressive neurodegenerative disorder
characterized by abnormal motor behaviours and fronto-parietal cortical dysfunction. Whether
cognitive skills are preserved is debated, but few cases have received detailed neuropsychological
testing. We tested a 52-year-old woman with a 10-month history of decline in skilled behaviours.
Neuropsychological testing revealed evidence of general cognitive decline and impairments in
episodic recall, visual scanning, and verbal fluency, in addition to features consistent with parietal
involvement such as Gerstmann’s syndrome (finger agnosia, agraphia, right/left disorientation,
acalculia) and apraxia. Our results suggest that cognitive decline can be an early symptom of
CBGD.
2028.128 ERP research on simplified operation for calculating, Dianzhi Liu, Xiting Huang
Southwest Normal University, China
ERP experiment is used on children’s Operation for Calculating for the first time.15 elementary
schoolchildren (age 8-9) were experiment In this study, children’s strategies physiological
mechanism is revealed: (1) Simplified calculation uses less brain energy than normal calculation,
and the difference between them is significant. The effect of the strategy training is proved
through physiological index for the first time. (2) The brain orientation also depends on the
alteration of Calculating methods. (3) Both Simplified calculation and not-Simplified calculation’s
activated areas are in the bilateral intraparietal, accorded further with the activation of the
approximate calculation and exact calculation of big numbers.
