Attention and how it relates to perceptiona multimodal exploration

Resumen

This doctoral dissertation explores the relationship between attention and perception. In spite of decades of exploratory research, agreement as to the negree to which attentional mechanisms are necessary for the perception of ones environment has yet to achieved. Additionally, it is not completely understood how the sensory modalities work conjointly, or independently, in order to create common percepts in everday life. The thesis is composed of five research articles, four of which have been, or are currently being, published in International journals (the fifth is under review). The articles that compose this thesis are: Sinnett, S. Costa. A, & soto-Faraco, S (2006). Manipulating inattentation blíndness within anda cross sensory modalities. Quarterly Journal of Experimental Psychology. 59 (8), 1425-1442 Toro,J.M. Sinnett, S& Soto- Faraco, S. (2005). Speech segmentation by statistical learming depends on attention. Congnition, 97, 25-34.

A dissociation betwenn visual and auditory hemi-inattention: Evidence from temporal order judgements. Neuropsychologia. Results from the experimentation carried out in these articles indicate that attention is indeed necessary for many different perceptual processes, as well as providing evidence suggesting a segregating a segregation of attentional resources between sensory modalities.
