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

Abstract

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 children diagnosed with ADHD (Combined type) based on DSM-IV classification were compared with 19 typically developing children matched on age, gender, and IQ. The participants performed an emotional face recognition while their brain activities were recorded using an event-related oscillation procedure.Results:The results indicated that ADHD children compared to normal group showed a significant reduction in the gamma band activity, which is thought to reflect early perceptual emotion discrimination for happy and angry emotions (P<0.05).Conclusion:The present study supports the notion that individuals with ADHD have some impairments in early stage of emotion processing which can cause their misinterpretation of emotional faces.

Reinvestigation of the Psychological Mechanisms of Construction Experience on Hazard Recognition Performance

“…Thus, the average power of the induced neural oscillatory activities in the gamma band (30-40 Hz), based on the 250-to 800-ms post-stimulus window, were extracted for the following statistical analysis. The center of induced gamma activity for construction-site pictures was over the parieto-occipital electrodes during the 0.25-0.8 s period (Figure 5b), in line with previous findings indicating a relationship between brain activity and visual information processing (Razavi et al, 2017).…”

Event-related brain oscillations in attention-deficit/hyperactivity disorder (ADHD): A systematic review and meta-analysis

“…Most studies (21 in the qualitative synthesis, 11 in the meta-analysis) investigated differences between ADHD and control groups in event-related alpha power, with fewer studies reporting effects for theta power (15 in the qualitative synthesis, 7 in the meta-analysis) and beta power (9 in the qualitative synthesis, 5 in the meta-analysis). Only 5 studies, none of which provided sufficient data for inclusion in the meta-analysis, examined gamma power (Baijot et al, 2017;Karch et al, 2012;Leroy et al, 2018;Sarraf Razavi et al, 2017;Yordanova et al, 2001). None of the eligible studies tested delta power.…”

Establishing the Relationship Between Attention Deficit Hyperactivity Disorder and Emotional Facial Expression Recognition Deficit: A Systematic Review

“…Muszkat et al (2015) suggested that FER deficits might be attributed to poor allocation of attention to specific cues (Muszkat et al, 2015). Consistent with this, some authors have proposed that deficits in sustained attention and visual processing play a role in FER, as supported by the observation of increased gamma oscillations in occipital regions during the early stages of facial emotion processing (Sarraf Razavi et al, 2017). Additionally, more robust functional connectivity has been observed in the frontal lobes of children with ADHD, which may indicate the abnormal transfer of information from the occipital lobe to the frontal lobe, that is, from the visual to the emotional processing center (Ansari Nasab et al, 2022).…”
