Increased sensitivity to sad faces in depressive ... - PubMed
Results: The group with higher depressive symptoms showed a higher sensitivity to sadness than those with lower depressive symptoms, indicating a relationship between negative bias in facial expression recognition and nonclinical depressive symptoms.
Sad faces increase the heartbeat-associated interoceptive ... - Nature
2019年1月23日 · Importantly, our Granger causality analysis provides the first evidence for the increased flow of heartbeat information from the RAI to the RdACC during sad face perception. Moreover, using a...
Brain mechanisms underlying the emotion processing bias in
2024年4月16日 · First, compared with the control group, patients with TRD showed increased amygdala responses to sad faces in the early stage (around 300 ms) and decreased amygdala responses to happy faces in...
Facial emotion processing in major depression: a systematic …
2011年11月7日 · The analysis of neural activation data shows that MDD patients are characterized by abnormalities within the common face processing network, indicating a mood-congruent processing bias particularly in the amygdala, insula and PHG, fusiform face area and putamen responsiveness.
The contribution of the upper and lower face in happy and sad …
2010年8月23日 · We used a happy/sad classification task and a psychophysical model to study the tuning properties of facial expression processors across viewing conditions. Using morphed faces, in this study we measured the extent to which classification of facial expressions depends on the intensity of a particular expression on either the upper or lower face.
“The many faces of sorrow”: An empirical exploration of the ...
In a first stage, participants were asked to select sad emotional faces and scene stimuli either characterized or not by a key suggested sadness-related characteristic: loneliness or melancholy or misery or bereavement or despair. In a second stage, another set of participants was presented with the selected emotional faces and scene stimuli.
Explaining Sad People’s Memory Advantage for Faces - PMC
2017年2月17日 · In this study, we aim to explore why sad people are more accurate at face recognition than happy people by investigating four potential hypotheses: enhanced expert face processing; increased motivation; defocused attention; and more diverse face sampling.
In this magnetoencephalography study of 32 healthy subjects of either sex, heartbeat-evoked responses (HERs), which reflect the cortical processing of heartbeats, were modulated by the perception...
Increased sensitivity to sad faces in depressive symptomatology: A ...
2018年11月1日 · Negative bias to sad emotional stimuli has repeatedly been identified as a cognitive feature of major depressive disorder, particularly in facial expression recognition. However, it is unknown how negative bias applies to facial expression recognition in individuals with depressive symptoms.
Sad faces increase the heartbeat-associated interoceptive information ...
2019年1月23日 · First, we showed that cortical heartbeat processing after the presentation of a sad face had significantly different spatiotemporal dynamics from that of a neutral face and that these differences were localized to the interoceptive network (AI, dACC), prefrontal areas (dlPFC) and basal ganglia (GP, putamen).
