The test administration time was approximately 40 minutes. The examiners were
Psychologists, graduate students from the School of Clinical Psychology of
the University of L'Aquila, Italy. The examiners were been blind to the research
objectives.
3 Results
The data have been analyzed by the computerized program 'Statistica'. The signi-
ficance level fixed was alpha <0.05.
Data submitted to statistical analysis were both accuracy and decision time.
First of all, we conducted a statistical analysis on the accuracy data. A repeated
measures ANOVA was showed no significative difference between the groups and
tests. This data was expected because we want' verified the efficiency in the se-
mantic ability.
A statistical analysis was conducted on the decision time (DT) in msec. The
Table 1 reports the means and standard deviation.

An 2x5 ANOVA showed significative difference between tasks neither be-
tween groups; no significative resulted the interaction groups x performance. The
Post-Hoc Analysis (LSD test) evidenced in verbal performance the Adult Groups
significatively faster than Young Group (<0,02), and than Elderly Group
(<0,008); in visual performance, the Young Group was faster than Junior Group
(<0,02).

4 Discussion and Conclusions
Our comparative study was focused on the performance (accuracy and response
time) of subjects with different age in order to study the influence of age on the
cognitive elaboration of information using information technology. Particularly,
our study wants to verify the ability to use the touch technology in verbal and
