Our studies examined the interactions between task type, site organization, and search procedure
formatting in information search tasks. If the organization is consistent with user expectations and
experience, user satisfaction and the probability of finding relevant topics increase, while the time
to find the information decreases. For effective utilization however, information must be organized
and displayed in a way that facilitates the task goals of the user. A significant finding is that the
compatibility between the task and presentation styles strongly affects a procedure’s usability.
Therefore, evaluation of information displays must be based on user goals and task context.
1044.4 The effects of event delay on knowledge synchronization and distributed collaborative
task performance, E. Wang, Purdue University, West Lafayette, IN, USA
Communication and collaboration delays during long-range space exploration are inevitable
because of the transmission problems (e.g. long transmission distance and low transmission
frequency). Maintaining knowledge synchronization and optimal team collaboration is the key to
ensure the success of such space missions. Therefore, the effects of event delays need to be
carefully investigated for improving knowledge synchronization and distributed collaborative task
performance. This study is an initial attempt to investigate the effects of event delay via Digital
Voice Intercommunication System in NASA Mission Control Center. The preliminary results
show that event delays significantly affect controller’s knowledge synchronization and
collaborative task performance.
1044.5 In-vehicle navigation information display: Integration of visual and auditory
presentation, X.H. Sun, K. Zhang, Institute of Psychology, Chinese Academy of Sciences,
Beijing, China
Our research focused on how to integrate visual and auditory navigation information to minimize
driver attention demands while driving. The conclusion of laboratory experiments was that: both
visual and audio navigation were helpful in driving; Audio guide was more effective than visual
guide. The location effect of visual information was not found. But some data indicated that, at
some specific positions, the combination of visual and audio information could improve driving
performance and decrease MWL. Both NASA-TLX and secondary task performance showed that
visual guide could not decrease MWL, but audio guide improve driving performance and decrease
MWL

1045.1 Representation of musical knowledge in the brain, M. Besson, D. Schoen, C. Magne,
CNRS – LNC, France
To determine how and where musical knowledge is represented in the brain, we conducted
experiments on musical notation using fMRI. Results showed that occipito-temporal and parietal
brain regions were more activated by reading musical scores than words or numbers. These
regions may be specifically linked to written music representations. The second series of
experiments was aimed at directly comparing pitch processing in language and music in both
adults and children musicians and non-musicians using ERPs. Results show similarities between
