The paper discusses the advantages of computer-aided testing in different areas of application. At
first the research literature on the equivalence of paper-and-pencil and computerized tests will be
discussed. The second part demonstrates how the computer can be used to measure hard to assess
constructs in a theoretical sound and objective manner by using peripheral equipment and
interactive videos. In the third part the benefits of computers during the test scoring and
interpretation phase are high-lightened focusing on computerized adaptive testing (CAT), Mixed
Rasch Models and new algorithms for statistical judgement formation applicable to the screening
of job applicants.

4038.1 An upper/lower visual field asymmetry in localization performance, Kamal Uddin,
Yuri Ninose, Nakamizo Sachio, Kyushu University, Japan
We examined localization performance employing 3 stimulus conditions: (i) no-saccade- observers
were to maintain gaze on the fixation point while target appeared for 1 s, (ii) saccade to on-targetthey
had to quickly saccade to and fixate on target remaining on for 1 s, and (iii) saccade to
off-target- they had to quickly saccade to the target appeared for 150 ms. Observers’ task was to
localize the target by clicking mouse cursor that appeared after150 ms following target termination.
Results revealed lower visual field superiority in no-saccade condition suggesting differential role
of upper and lower hemi-retina in localization performance.
4038.2 The effects of direction of vertex in judging positions of vertex of holes, Yuming Xuan,
Xiaolan Fu, Institute of Psychology, Chinese Academy of Sciences, China
Researchers have reported that observers are faster at judging the position of convex vertices than
concave ones (Perception 30 (2001) 1295), and a reversal of the relative speeds were found when
the same contours were presented as holes instead of objects using a figural manipulation of
figure/ground (Cognition 87 (2003) 33). 2 experiments with revised paradigm were conducted to
further study the relationship between polarity and direction of vertex in judging positions of
vertex of holes. Results showed that the direction of vertex affected participants' performances.
Related issues on perception of shape of objects and holes were also discussed.
4038.3 The study of visual-motor perception and its relationship with social psychological
adjustment of elementary students, Fariba Khoshbakht, Morteza Latifian, Iran
The purpose of this study was to find out the relationship between social psychological adjustment
and visual -motor r perception. For this purpose Bender-Gestult Test and the Children Social
Behavior Scale were administrated to 198 girl students from elementary school. The result of the
study showed that: There was a significant relationship between depression and visual-motor
perception in first and third grade, relational aggression and visual-motor perception in third and
fourth grade and social adjustment behavior and visual-motor perception in fifth grade. The results
showed that age was found to correlate significantly.
