2028.84 The role of serotoninergic system genes in verbal memory, Margarita Alfimova,

Effects of two genes involved in serotonin neurotransmission on short-term memory (a word span),
long-term mediated memory (the Pictogramm method by A. Luria), and semantic verbal fluency
were evaluated in 173 healthy adults. T102C and A1438G polymorphisms in the serotonin
receptor 2A gene, as well as intron 2 VNTR and LPR polymorphisms of the serotonin transporter
gene were studied. Significant associations were found between the mediated memory and the
serotonin receptor T102C and the serotonin transporter VNTR polymorphisms. These findings
suggest that allelic variations of the genes implicated in serotoninergic functions may play a role
in long-term mediated memory.
2028.85 A behavior-genetic study on adolescent temperament assessed through The Rusalov
Structure of Temperament Questionnaire (STQ): Results from a Russian sample, Sergei Malykh,

Russian Federation
As a part of a Moscow longitudinal twin project, this study was aimed to explore genetic and
environmental contributions to temperament in adolescence. 85 pairs of monozygotic (MZ) and 64
pairs of same-sex dizygotic (DZ) Russian twins aged 12-14 years completed the children version
of STQ. Model-fitting analyses revealed significant genetic influences on 3 of the 8 STQ
dimensions - Social Temp (a=60%; c=0.59; p=0.96), Emotionality (a=66%; c=0.17; p=1.00) and
Social Emotionality (a=66%; c=4.34; p=0.36). Non-shared environmental effects explained the
rest of the total variance in these dimensions. Individual differences in the other STQ dimensions
were due to environmental factors.
2028.86 Higher sensitivity, but lower sensibility for vection-induced nausea in Chinese as
compared to Caucasian subjects, Fang Pan 1 , Sandra Kellermann 2 , Ursula Stockhorst 2 , Paul
Enck 2 , Sibylle Klosterhalfen 2 , 1 School of Medicine, China, 2 University Hospitals Tuebingen,
Germany
In 48 subjects (24 Caucasian, 24 Chinese) nausea was induced by circular vection (CV) in a
rotation drum, and symptoms (SR), time for first CV as well as the total rotation tolerance (RT)
were noted. Results: Time to CV was not different between the groups, but RT was significantly
shorter in Chinese; age and gender did not determine CV and RT. SR was significantly higher in
Caucasians but also affected by gender. Maximal SR and number of symptoms were equal for
both groups. SR prior and post rotation were not correlated to CV and RT.
2028.87 Sex limitation in cognitive abilites at age 16, Qi Christine Liu, University of Virginia,
USA
A multivariate structural equation model was used to examine sex limitation in cognitive abilities
of 16-year-olds in cognitive abilities, including verbal, spatial, perceptual speed, and memory,
