AI Article Synopsis
- - The study explores how individuals with high social anxiety (HSA) versus low social anxiety (LSA) detect facial expressions, using Signal Detection Theory to analyze their performance on a change-detection task featuring various facial expressions.
- - Results showed that HSA individuals were generally better at noticing changes in facial expressions, especially when judging angry faces, while LSA individuals performed better with clear, prototypical angry expressions.
- - The study's findings suggest that people with higher social anxiety are not only more sensitive to changes in expressions but also more lenient in classifying angry expressions as unchanged, although the sample used limits the broader applicability of these results.
Article Abstract
Background And Objectives: Previous research has not established a consensus on the ability of higher socially anxious individuals to detect facial expressions. The purpose of this study was to examine this issue using Signal Detection Theory (SDT) as a framework.
Methods: Participants with higher levels of social anxiety (HSA) and lower levels of social anxiety (LSA) were instructed to complete a change-detection task. Prototypical (faces with congruent eyes and mouth, i.e., happy eyes and a smiling mouth) and blended (faces with incongruent eyes and mouth, i.e., neutral eyes and a happy mouth) facial expressions were used as stimuli. Participants had to decide whether the facial expression indicated by the cue was "the same" or "different".
Results: The results revealed that the HSA group had a higher sensitivity (d') to detect changes in facial expressions compared to the LSA group. The LSA group had a higher d' to detect prototypical angry expressions than to blended angry expressions. However, this difference was not found in the HSA group. In addition, the HSA group displayed more leniency in judging angry expressions as being the same compared to the LSA group.
Limitations: The external validity of the study is limited by the sample (low levels of depression, mostly male).
Conclusions: Higher socially anxious individuals are more sensitive in detecting changes and are more lenient in judging changes in angry expressions.

Impact of chronic intranasal oxytocin administration on face expression processing in autistic children: a randomized controlled trial using fMRI.
Mol Autism
December 2024
Department of Neurosciences, Center for Developmental Psychiatry, KU Leuven, Leuven, Belgium.
Background: Difficulties with (non-verbal) social communication, including facial expression processing, constitute a hallmark of autism. Intranasal administration of oxytocin has been considered a potential therapeutic option for improving social difficulties in autism, either by enhancing the salience of social cues or by reducing the social stress and anxiety experienced in social encounters.
Methods: We recorded fMRI brain activity while presenting neutral, fearful and scrambled faces, to compare the neural face processing signature of autistic children (n = 58) with that of matched non-autistic controls (n = 38).

The role of the eye region in interpersonal communication and emotional recognition is widely acknowledged. However, the influence of mouth expression on perceiving and recognizing genuine emotions in the eye region, especially with limited attentional resources, remains unclear. Thirty-four participants in this study completed a dual-target rapid serial visual presentation (RSVP) task while their event-related potential (ERP) data were simultaneously recorded.

The Chromodomain Helicase DNA-binding (CHD) protein family is ATP-dependent chromatin remodeling proteins that utilize energy produced by ATP hydrolysis to regulate chromatin structure and thereby modulate gene expression. The earliest report of a CHD3 gene mutation was by O'Roak, who found it during whole exome sequencing of 189 autism families in 2012. In 2018, Snijders Blok systematically assessed the autosomal dominant neurodevelopmental disorder caused by CHD3 gene damage, known as Snijders Blok-Campeau syndrome (SNIBCPS, OMIM 618205).

Both the upper and lower jaws develop from cranial neural crest cells (CNCCs) populating the first pharyngeal arch in all gnathostomes. Previous studies showed that the Edn1/Ednra-Dlx5/Dlx6-Hand2 signaling pathway is necessary for lower jaw formation and that ectopic expression of or throughout the CNCCs partly transformed the upper jaw to lower jaw structures, but the molecular mechanisms regulating upper jaw development remain unclear. Here we show that the basic helix-loop-helix transcription factor Twist1 is required for upper jaw development.

BMC Med Ethics

Background: Respect for patient autonomy, the principle that patients are capable to make informed decisions about medical interventions, is fundamental in present-day medicine. However, if a patient's request is medically not indicated, the practitioner faces an ethical dilemma represented by the conflict of the principles of patient autonomy, beneficence, and maleficence. Adjacent to topics such as medical assistance in dying and healthy limb amputation, this ethical dilemma also manifests in the care of the maxillofacial region (the oral cavity and its surroundings), an area crucial to esthetic appearance, but also to everyday functions including mastication, speech, and facial expression, all of which are related to well-being.
