In-Depth Information
repeated-measures ANOVA with stimulus modality (V, A and VA) and stimulus
location (left, right and central) as the subject factors.
3 Results
3.1 Response Times
Fig.4. showed the RTs of V, A and VA stimuli on left, right and central locations. The
ANOVA analysis of variance revealed a significant effect of the main factors, stimu-
lus modality [F (2, 48) =27.4, P<.001] and stimulus location [F (2, 48) =17.0,
P<.001]. There was a significant interaction between stimulus modality and stimulus
location [F (4, 48) =4.5, P<.05]. For the stimulus modality, RTs to VA target stimuli
were significantly faster than that of unimodal V target stimuli and unimodal A target
stimuli anywhere. For the stimulus location, RTs to V and VA target stimuli on the
central location were faster than that on the left and right location.

3.2 Hit Rates
Fig. 5 showed the HRs of V, A and VA stimuli on left, right and central locations.
The ANOVA analysis of variance revealed that a significant effect of the main factors
on stimulus modality [F (2, 48) =60.4, p<.001]. For the stimulus modality, HRs to A
and VA target stimuli were more accurate than that of unimodal V target stimuli. For
the stimulus location, HRs to V target stimuli on the central location was more accu-
rate than that on the left and right location.
