On the other hand, even though attention had to be divided the attentional resources did not seem to be exhausted, since the identification of the direction of the auditory target and the quality of SPEM were unaffected by the congruence between visual and auditory motion stimuli.
Moving visual stimuli also capture the perceived motion direction of the auditory stimulus [5] [7].
The sequence of trials from the different conditions was randomized and the direction of the auditory stimulus was counterbalanced for all conditions.
The behavioural data shows that under the incongruent condition there was no drop in performance, neither in identification of the direction of the auditory target nor in the quality of SPEM.
Pursuit eye movements towards the visual target activated, irrespective of the direction of the auditory sound source, the well-established pursuit network, which included cuneus, precuneus, MT, posterior parietal cortex, supplementary eye fields, and frontal eye fields.
Secondly, an analysis of variance (ANOVA) was performed on the mean number of associations between visual and auditory stimuli correctly recognized, with the direction of association (visuo-auditory and audio-visual) and delay (immediate and delayed recognition) as within-subjects factors and, learning methods (multisensory or classic) as between-subjects factor (Figure S2).
But Daniel J. Strauss will be at CCRMA on Friday to talk about "Decoding Spatial Auditory Attention Using a Vestigial Pinna-Orienting System in Humans". Decoding auditory perception from brain signals is certainly one of the more interesting directions for auditory research.
However, this model failed half of the time in predicting the direction of PSE shift when auditory and visual durations were incongruent, in particular under the auditory intersensory conditions of the Loom (t1,16 = 2.1, p≤0.008) and Reverse (t1,20 = 2.08, p≤0.001) experiments.
