Smith, Danielle; Ropar, Danielle; Allen, Harriet A. – Journal of Autism and Developmental Disorders, 2017
In autism spectrum disorder (ASD), atypical integration of visual depth cues may be due to flattened perceptual priors or selective fusion. The current study attempts to disentangle these explanations by psychophysically assessing within-modality integration of ordinal (occlusion) and metric (disparity) depth cues while accounting for sensitivity…

Geringswald, Franziska; Herbik, Anne; Hofmüller, Wolfram; Hoffmann, Michael B.; Pollmann, Stefan – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015
Allocation of visual attention is crucial for encoding items into visual long-term memory. In free vision, attention is closely linked to the center of gaze, raising the question whether foveal vision loss entails suboptimal deployment of attention and subsequent impairment of object encoding. To investigate this question, we examined visual…

Papadopoulos, Konstantinos; Koustriava, Eleni; Kartasidou, Lefkothea – Journal of Special Education, 2012
The aim of this study is to examine the ability of children and adolescents with visual impairments to code and represent near space. Moreover, it examines the impact of the strategies they use and individual differences in their performance. A total of 30 individuals with visual impairments up to the age of 18 were given eight different object…

Gawryszewski, Luiz G.; Carreiro, Luiz Renato R.; Magalhaes, Fabio V. – Psicologica: International Journal of Methodology and Experimental Psychology, 2005
A non-informative cue (C) elicits an inhibition of manual reaction time (MRT) to a visual target (T). We report an experiment to examine if the spatial distribution of this inhibitory effect follows Polar or Cartesian coordinate systems. C appeared at one out of 8 isoeccentric (7[degrees]) positions, the C-T angular distances (in polar…
