Human social interactions depend on the construction of emotional meaning. The present study used event-related potentials to investigate the neural features of emotional violation processing in facial expressions, emojis, and emotion words. Behavioral results showed emotion congruency effects among facial expressions, emojis, and emotion words. Emotional violations resulted in a longer response time than emotion congruent conditions in happy context conditions. Responses to angry faces were slower in angry sentences than in happy sentences. As expected, the classic N400 effect was obtained for the emotional violations among facial expressions, emojis, and emotion words. Emotional violations resulted in more negative-going N400 amplitudes. Moreover, the N400 effects elicited by facial expressions and emojis were significantly smaller than emotion words, and there were no significant differences in N400 effects between facial expressions and emojis. The findings suggest that the emotional violation processing of facial expressions, emojis, and emotion words could be reflected in an electrophysiological index of semantic processing, and that emotional violation elicited higher levels of semantic retrieval. In addition, there were differences between nonverbal and verbal information processing in emotional violation, while the emotional violation of words induced greater semantic retrieval demands than facial expressions and emojis.

While telegenetic counseling has increased substantially since the start of the COVID-19 pandemic, previous studies reported concerns around building rapport, nonverbal communication, and the patient-counselor relationship. This qualitative evaluation elicited feedback from genetic counselors, referring clinicians, and patients from a single healthcare organization to understand the user-driven reasons for overall satisfaction and experience. We conducted 22 in-depth, semi-structured interviews with participants from all 3 groups between February 2022 and February 2023.

Waardenburg syndrome type 2 (WS2) is an autosomal dominant disorder characterized by congenital sensorineural hearing loss, blue iris, and abnormal pigmentation of the hair and skin. WS2 is genetically heterogeneous, often resulting from pathogenic mutations in SOX10 gene. We identified a novel heterozygous frameshift mutation in SOX10 (NM_006941.

Background: Deepening of the nasolabial fold (NLF), drooping of the nasal tip, and facial expressions perceived as angry face, are common esthetic concerns. However, no studies have correlated this set of signs and symptoms with common anatomical causes. We review anatomical considerations of the region and propose a combined treatment modality.

Facial emotion recognition (FER), a key component of social cognition, plays a critical role in social interactions. In the aging process, FER among older adults holds significant potential as a tool for diagnosing cognitive function or enhancing interpersonal relationships. However, research in this area remains limited.

Sperm-associated antigen 9 (SPAG9) is a member of cancer-testis antigen, having characteristics of a scaffold protein, which is involved in the c-Jun N-terminal kinase JNK signaling pathway, suggesting its key involvement in different physiological processes, such as survival, apoptosis, tumorigenesis, and cell proliferation. We identified two families (A and B) having multisystem features like coarse facial features, albinism, cataracts, skeletal abnormalities, and developmental delay. Whole genome sequencing (WGS) in families A and B revealed a homozygous frameshift variant (c.
