28th International Congress of Psychology August 8 ... - U-netSURF

For Japanese respondents, the difference between anxiety-present and anxiety-absent items was
stronger than between state and trait anxiety. A greater difference between Japanese and American
subjects was also found for anxiety-absent than anxiety-present items. These findings demonstrate
the importance of considering cross-cultural issues in adapting psychometric tests.
2010.6 SWS-survey: Research model for cross-cultural assessment, R.F. Ostermann, Fairleigh
Dickinson University, Staunton, VA, USA
With World Federation for Mental Health sponsorship, over 800 professionals in 22 countries
participated in developing the 200-item SWS-Survey, a self-administered questionnaire of six
scales regarding Stress and Support indicators of one’s SOCIOENVIRON, WORK and SELF, plus
two scales for POOR and GOOD MENTAL HEALTH. The SWS research model, available for
replication in other countries, includes: original, basic American-English text, bi-lingual,
multi-disciplinary groups in each country for native language translation with certified back
translation, and item-by-item content validation considering separate gender utility. The SWS
model, available for replication, provides for universal and separate country-group scoring.

Sleep states and memory consolidation: Evidence from animal and human studies
Convener and Chair: C. Smith, Canada
2011.1 Evidence for differential functions of slow wave sleep and rapid eye movement sleep in
human memory consolidation, U. Wagner, University of Lübeck, Lübeck, Germany
Sleep after learning enhances memory consolidation compared to wakefulness. To investigate the
differential roles of slow wave sleep (SWS) and rapid eye movement (REM) sleep for this process
in humans, we compared the effects of early, SWS dominated sleep and late, REM sleep
dominated sleep on memory consolidation in a variety of tasks. Our results point to a specific
beneficial role of SWS in the formation of explicit (declarative) memory, which depends on the
hippocampus, whereas REM sleep appears to be more favorable for the formation of
hippocampus-independent implicit (nondeclarative) types of memory and the processing of
emotional materials.
2011.2 Neural correlates of memory consolidation during human sleep, P. Peigneux, University
of Liege, Liege, Belgium
Functional brain imaging studies in humans have shown that the brain structures engaged in the
learning process during wakefulness may be re-activated during sleep. Experience-dependent
reactivations of neuronal ensembles have been reported in neocortical and hippocampal regions
during REM and non-REM sleep states, respectively, using procedural and declarative memory
tasks. In addition, learned material content and acquisition level modulate cerebral reactivation
during post training REM sleep. Conversely, modifications of hippocampal activity during
non-REM sleep eventually lead to post-night behavioral performance improvement. These data
support the hypothesis that sleep states contribute to the reprocessing and strengthening of specific
memories.
