A deafening flash! Visual interference of auditory signal detection.
In some people, visual stimulation evokes auditory sensations. How prevalent and how perceptually real is this? 22% of our neurotypical adult participants responded 'Yes' when asked whether they heard faint sounds accompanying flash stimuli, and showed significantly better ability to discriminate visual 'Morse-code' sequences. This benefit might arise from an ability to recode visual signals as...
متن کاملInfluence of Correlated Visual Cues on Auditory Signal Detection
Two experiments investigated the effects on aUditory signal detection of introducing visual cues that were partially correlated with the signal events. The results were analyzed in terms of a detection model that assumes that such cue-signal correlations will not affect sensitivity, but will instead cause the subject to develop separate response biases for each cue. The model specifies a functi...
متن کاملVisual and Auditory Complications during Deferasirox Therapy in Beta-thalassemia
Background: Deferasirox is an oral iron chelator widely used to treat iron overload in patients with transfusion-dependent β-thalassemia. This study investigated the prevalence of visual and auditory complications caused by deferasirox. Materials and Methods: This cross-sectional study included 156 patients aged less than 18 years with transfusion-dependent β-thalassemia and deferasirox iron...
متن کاملSignal detection indices in schizophrenics on a visual, auditory, and bimodal Continuous Performance Test.
Signal detection indices (perceptual sensitivity) were calculated to compare performance of 24 male schizophrenic inpatients and 24 controls (12 alcoholics and 12 normals) on 4 different CPT-tests. A standard version (St) employed 1 target (P = 0.166) and 5 nontargets. In condition V stimuli were presented visually, in condition A acoustically and in condition VA bimodally (1 target (P = 0.333)...
متن کاملCuing mechanisms in auditory signal detection.
Detection of auditory signals under frequency uncertainty can be improved by presenting cues to the listeners. Since various cues have been found to differ in effectiveness, three conceivable mechanisms were considered which might account for these differences. Cuing might reduce the number and/or width of the employed auditory filters or listening bands. Also, cues could modulate the precision...
