{"pk":28361,"title":"Computational Model of Spatial Auditory Attention in ACT-R","subtitle":null,"abstract":"We present an extension to the ACT-R audition module developed to support models of spatial auditory attention. Thisextension adds support for spatial sounds and models a gradient of spatial auditory attention over 180 in the frontalhorizontal plane. This spatial gradient represents the attentional bias created from interaction between top-down (goaldriven) attention and bottom-up (salient) attention, represented by a Gaussian and inverse Gaussian curve respectively.Response time to a sound is modeled using a calculated attentional bias, affected by the current goal location and thesound location. This ACT-R extension is used to model a behavioral task where subjects were told to attend to a spatiallocation and respond to sounds at attended and distractor locations. By incorporating this model into ACT-R, we will gaininsights into the interaction between spatial auditory attention and other other cognitive processes, such as learning andmemory.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Abstracts-Posters","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6hj8m2p9","frozenauthors":[{"first_name":"Jaelle","middle_name":"","last_name":"Scheuerman","name_suffix":"","institution":"","department":""},{"first_name":"Maxwell","middle_name":"T.","last_name":"Anderson","name_suffix":"","institution":"","department":""},{"first_name":"K.
