Adaptive mechanisms of visual motion discrimination, integration, and segregation
2021, Vision ResearchA neural index of inefficient evidence accumulation in dyslexia underlying slow perceptual decision making
2021, CortexCitation Excerpt :Noise exclusion is therefore necessary to form a perceptual filter and isolate the signal dots to detect motion (Dakin et al., 2005). Both integration and segregation have been recognised as competing visual forces previously (Braddick, 1993; Watamaniuk et al., 2003) and have been proposed to have distinct neural mechanisms (McDonald et al., 2013). Thus, it may not be the integration of motion information that is dysfunctional in dyslexia but rather an inability to segregate noise from signal information (Conlon et al., 2013).
No effect of feedback, level of processing or stimulus presentation protocol on perceptual learning when easy and difficult trials are interleaved
2020, Vision ResearchCitation Excerpt :By contrast, receptive fields in higher cortical areas such as V3, V4 and V5, are much larger, and pool the incoming sensory information from lower level receptive fields (Burr & Thompson, 2011; Gilbert et al., 2001) across features such as space, time, speed, direction of motion and spatial frequency (Burr & Thompson, 2011; Gilbert, Sigman, & Crist, 2001; Felleman & Van Essen, 1987; Furlan & Smith, 2016; Hubel & Wiesel, 1965; Mikami, Newsome, & Wurtz, 1986; Movshon, Thompson, & Tolhurst, 1978; Sillito, Cudeiro, & Jones, 2006; Zeki, 1974). Local and global tasks have been developed in order to selectively assess these levels of processing (Newsome et al., 1989; Braddick, 1993; Gilbert et al., 2001; Bex & Dakin, 2002; Ostwald, Lam, Li, & Kourtzi, 2008; Amano, Edwards, Badcock, & Nishida, 2009; Burr & Thompson, 2011; Nishida, 2011). It should be noted that formal definitions of tasks for “local” and “global” processing do not exist, and the distinction between the two is not always clear cut, and therefore we propose these working definitions of local and global processing tasks.
Sensory loss due to object formation
2020, Vision ResearchCitation Excerpt :For motion, it is well accepted that some form of segmentation occurs before motion information is integrated within segmented objects. Clearly, it would make no sense to integrate motion information across two distinct objects because these different objects are free to move in different directions and different speeds (Braddick, 1993; Masson & Perrinet, 2012). In comparison to the motion literature, the importance of segmentation in scene analysis is encountered less often in studies on binocular vision.
