Investigation of the effects of auditory and visual stimuli on attention

OpenAlex İngilizce

Attentional resources limit our perceptual capacities. One vital point is whether these resources are allotted severally to every sense or shared between them. We addressed this problem via means of topics to carry out a dual-task, both in the same modality or other modalities (visual and auditory). The primary task is to count the number of passes of the participants while watching the video that requires visual and auditory attention. Concurrently, they were also asked to notice the pure tones and visual events in the song during the video while counting their pass numbers. The results show that while the auditory task reduced the detection ability visual events task, the dual-task had a significant effect. Previous studies support that tasks requiring simultaneous auditory and visual attention affect each other. Our results have clear implications for showing that performance decreases in dual-task as the perceptual load increases.
