Evidence Accumulation and the Moment of Recognition: Dissociating Perceptual Decision Processes Using Fmri

Dissociating Early and Late Error Signals in Perceptual Recognition

Decisions about object identity follow a period in which evidence is gathered and analyzed. Evidence can consist of both task-relevant external stimuli and internally generated goals and expectations. How the various pieces of information are gathered and filtered into meaningful evidence by the nervous system is largely unknown. Although object recognition is often highly efficient and accurat...

سازمان ادراکی و انسجام مرکزی حین پردازش‌های دیداری در کودکان اُتیسم: شواهدی برای از هم گسیختگی ارتباطات کارکردی در مغز اُتیستیک

Objective: A variety of evidence demonstrate altered perceptual functioning during visual processing in the brain of children with autism.it possibly is related to or the cause other diagnostic symptom in autism spectrum. In the present study visual perceptual organization in autistic children is studied. These processes require central coherence and typical functional connectivity among neural...

Emotional Face Recognition in Children With Attention Deficit/Hyperactivity Disorder: Evidence From Event Related Gamma Oscillation

Introduction: Children with attention-deficit/hyperactivity disorder (ADHD) have some impairment in emotional relationship which can be due to problems in emotional processing. The present study investigated neural correlates of early stages of emotional face processing in this group compared with typically developing children using the Gamma Band Activity (GBA). Methods: A total of 19 childre...

Task relevance differentially shapes ventral visual stream sensitivity to visible and invisible faces

Top-down modulations of the visual cortex can be driven by task relevance. Yet, several accounts propose that the perceptual inferences underlying conscious recognition involve similar top-down modulations of sensory responses. Studying the pure impact of task relevance on sensory responses requires dissociating it from the top-down influences underlying conscious recognition. Here, using visua...
