How can the person with simultanagnostic vision from an early age give an opinion of this nature? Doesn&#8217;t their simultanagnosia preclude them from providing such an analysis?<\/p>\n<p>Recognising this conundrum, we have also sought the help from an adult with acquired simultanagnosia during teenage years who has the facility to compare her current vision with her memory of her previous &#8216;normal&#8217; vision. This witness has affirmed that what we are now showing has great verisimilitude to her actual simultanagnostic visual experiences.<\/p>\n<p>Another way we have sought to ensure that what we are showing is as close as possible to what those who experience simultanagnosia every day, is to recognise that simultanagnosia is a dynamic, not a static phenomenon and that it becomes more marked when looking at greater complexity. This means that when viewing the most constrained visual emulations of simultagnostic vision those with the condition are least affected by it, because the peripheral masking we have created becomes evident to them owing to the overall diminished complexity of the simulated imagery.<\/p>\n<p><strong>Validation Team<\/strong>\u00a0(each with a diagnosis of\u00a0<span class=\"tooltip tooltipstered\" data-tooltip-content=\"#tooltip_content\" data-link=\"6\" data-content=\"A functional visual pathway running through a bundle of brain nerve fibres called the superior longitudinal fasciculus from the occipital lobes to the posterior parietal lobes.\">dorsal stream<\/span>\u00a0dysfunction and validated simultanagnostic difficulties)<br \/>Three Able adults with\u00a0<span class=\"tooltip tooltipstered\" data-tooltip-content=\"#tooltip_content\" data-link=\"6\" data-content=\"A functional visual pathway running through a bundle of brain nerve fibres called the superior longitudinal fasciculus from the occipital lobes to the posterior parietal lobes.\">dorsal stream<\/span>\u00a0dysfunction from birth.<br \/>One able adult with acquired\u00a0<span class=\"tooltip tooltipstered\" data-tooltip-content=\"#tooltip_content\" data-link=\"6\" data-content=\"A functional visual pathway running through a bundle of brain nerve fibres called the superior longitudinal fasciculus from the occipital lobes to the posterior parietal lobes.\">dorsal stream<\/span>\u00a0dysfunction as a teenager.<br \/>One parent of a child aged over ten with\u00a0<span class=\"tooltip tooltipstered\" data-tooltip-content=\"#tooltip_content\" data-link=\"6\" data-content=\"A functional visual pathway running through a bundle of brain nerve fibres called the superior longitudinal fasciculus from the occipital lobes to the posterior parietal lobes.\">dorsal stream<\/span>\u00a0dysfunction since birth.<br \/>One parent of a child aged over ten with acquired\u00a0<span class=\"tooltip tooltipstered\" data-tooltip-content=\"#tooltip_content\" data-link=\"6\" data-content=\"A functional visual pathway running through a bundle of brain nerve fibres called the superior longitudinal fasciculus from the occipital lobes to the posterior parietal lobes.\">dorsal stream<\/span>\u00a0dysfunction.<\/p>\n<p><strong>Our thanks to School of Computer Science Students:<\/strong><br \/>Hafeez Abdul-Rahaman 2018\/9 Final Year Undergraduate Project<br \/>Cristina Bikanga Ada 2020\/21 Final Year Undergraduate Project<br \/>Cameron Wilson 2020\/21 Masters Degree Project<\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/med.st-andrews.ac.uk\/vision-in-childhood\/wp-content\/uploads\/sites\/33\/2021\/11\/1607330128.png&#8221; title_text=&#8221;1607330128&#8243; force_fullwidth=&#8221;on&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text admin_label=&#8221;Txt-Image Caption&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; custom_margin=&#8221;-25px||||false|false&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"font-size: 12px\">One of our virtual reality classrooms.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phase 2: CVI-SIM Virtual Reality Progress VideosWe continue our partnership with the charity CVI Scotland, and for the 2020\/21 academic year worked with some exceptional students from the Department of Computer Studies, to develop our work creating simulations of the experience of CVI.
