In order to gain a complete mechanistic understanding of the interplay between conflict and cognitive control, we need to examine the dynamics of within-trial processes that underlie decisions. Three diffusion decision model variants (DDM) have attempted to capture cognitive control on a trial-by-trial basis (SSP: shrinking spotlight model, White, Ratcliff et al. 2011; DSTP: dual-stage two-phase model of selective attention, Hubner et al. 2010; DMC: diffusion model for conflict tasks, Ulrich et al. 2015). These models assume an increase in selective attention for the relevant stimulus over the course of a trial. We contend that the decision process in tasks involving evidence for multiple alternatives is not driven by time, but rather by perceptual conflict. Here, we present a comparison of SSP model variants incorporating different attentional drives (time-based vs. conflict-based) and mechanisms for competition between accumulators (feed-forward inhibition vs. lateral inhibition). 2017-10-30 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu150003429232711 http://rave.ohiolink.edu/etdc/view?acc_num=osu150003429232711 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
