Preliminary studies in children and adults with Attention Deficit Hyperactivity Disorder (ADHD) report both hypo-responsiveness and hyper-responsiveness to sensory stimuli, as well as problems modulating sensory input. As it has been suggested that those with ADHD exist at the extreme end of a continuum of ADHD traits, which are also evident in the...

Microsaccades are involuntary, small, jerk-like eye-movements with high-velocity that are observed during fixation. Abnormal microsaccade rates and characteristics have been observed in a number of psychiatric and developmental disorders. In this study, we examine microsaccade differences in 43 non-clinical participants with high and low levels of...

... They have the potential to inform models of MS performance and oculomotor function in general, given that MS and saccades are believed to share performance characteristics and the same neural generator. In addition, given how some MS characteristics differ in atypical and visually impaired populations (e.g., Otero-Millan, Schneider, Leigh, Macknik, & Martinez-Conde, 2013;Dankner et al., 2017;Panagiotidi, Paul, & Tom, 2017;Alexander, Macknik, & Martinez-Conde, 2018), future research could examine whether the MS pattern we observed differs in such populations. ...
... The advantages of this task are its simplicity, which renders it ideal for research with special populations, as well as the relatively low number of trials needed to establish the width of the simultaneity window . A large body of research has assessed audiovisual simultaneity windows across different stimulus types (Eg & Behne, 2015;Horsfall et al., 2021;Leone & McCourt, 2015;Roseboom et al., 2009;Van Eijk et al., 2008;Vroomen & Keetels, 2020;Zampini et al., 2005) and modality combinations (Machulla et al., 2016) in typically developed individuals of all ages (Basharat et al., 2018;Chen et al., 2016;Hillock et al., 2011;Hillock-Dunn & Wallace, 2012;Noel et al., 2016) as well as individuals with neurodevelopmental disorders (Donohue et al., 2012;Panagiotidi et al., 2017;Stevenson et al., 2014), in persons with sensory impairments (Peter et al., 2019;Schormans & Allman, 2018;Shayman et al., 2018;Stevenson, Park, et al., 2017a, Stevenson, Sheffield, et al., 2017b, and in animals (Schormans et al., 2017). ...
