2019 Brain Imaging and Behavior  
Furthermore, we investigated whether it was possible to decode an individual's subjective threat perception from patterns of whole-brain activity to threatening stimuli in the different emotional contexts  ...  Interestingly, we were able to accurately predict the subjective threat perception index from the pattern of brain activation to threat only during the directed away context.  ...  Acknowledgments We thank Lucas Rego Ramos for helping during the collection of the fMRI data.  ...

Neural Population Decoding Reveals the Intrinsic Positivity of the Self

Robert S. Chavez, Todd F. Heatherton, Dylan D. Wagner

Hans Eysenck's interface between the brain and personality: Modern evidence on the cognitive neuroscience of personality

Rachel L.C. Mitchell, Veena Kumari
2016 Personality and Individual Differences  
Specifically, there is a robust relationship between neuroticism and the functioning of several emotion processing networks in the brain, particularly during exposure to negative stimuli.  ...  We present clear evidence that, as proposed by Eysenck nearly half-a-century ago, these traits relate meaningfully to the functioning and structure of various cortical and limbic brain regions.  ...  Can we distinguish the types of people (i.e., personality types) skilled in decoding nonverbal emotion cues from those with difficulties interpreting such cues based on typical patterns of brain activation  ...

Alexithymia slows performance but preserves spontaneous semantic decoding of negative expressions in the emostroop task

Courtney K. Hsing, Alicia J. HofelichMohr, R. Brent Stansfield, Stephanie D. Preston
2013 International Journal of Psychological Research  
The current study was designed to determine if trait alexithymia was associated with impaired early semantic decoding of facial emotion.  ...  Moreover, their impairment does not appear to extend uniformly across negative emotions and is not specific to angry or threatening stimuli as previously reported, at least during early processing.  ...  Trait or mood induced attention to negative affect is known in other studies to delay responses, as in clinical Emotional Stroop tasks (McKenna & Sharma, 1995) .  ...

Alcohol attenuates amygdala–frontal connectivity during processing social signals in heavy social drinkers

Stephanie M. Gorka, Daniel A. Fitzgerald, Andrea C. King, K. Luan Phan
2013 Psychopharmacology  
Given that affective processing involves dynamic interactions between the amygdala and the prefrontal cortex (PFC), alcohol's effects are likely to extend beyond regional changes in brain activity to changes  ...  Rationale Convergent evidence shows that alcohol exerts its effects on social behavior via modulation of amygdala reactivity to affective stimuli.  ...  Acknowledgments This study was supported by a Brain Research Foundation Grant awarded to ACK and KLP. Conflicts of interest All authors declare that they have no conflicts of interest.  ...

2018 NeuroImage: Clinical  
Multivariate pattern analysis assessed whether treatment response in those receiving CBTp (n = 22) could be predicted by pre-therapy neural responses to facial affect that was either threat-related (ambiguous  ...  Psychotic symptom improvement was predicted by neural responses to threat-related affect across sensorimotor and frontal-limbic regions, whereas affective symptom improvement was predicted by neural responses  ...  We would also like to acknowledge the participants of the study for their commitment to this research.  ...

Neural Underpinnings of the Perception of Emotional States Derived From Biological Human Motion: A Review of Neuroimaging Research

Julia Bachmann, Jörn Munzert, Britta Krüger
2018 Frontiers in Psychology  
Moreover, neural activation seems to depend on task characteristics, indicating that certain structures are activated even when attention is shifted away from emotional body movements.  ...  Whereas most brain regions clearly display an increased response to emotional body movements in general, some structures respond selectively to negative valence.  ...  They found that the TPJ showed increased activation regardless of whether participants inferred either affective states or personality traits.  ...

2011 Psychological bulletin  
Fine-grain consideration of social transactions during pain leads to an appreciation of sociobehavioral events affecting both suffering persons as well as caregivers.  ...  Our examination considers knowledge from a variety of perspectives, including clinical health psychology, social and developmental processes, evolutionary psychology, communication studies, and behavioral  ...  Acute noxious stimuli activate several brain areas, but this activation does not necessarily correspond directly to self-reports of pain (Bornhövd et al., 2002; Büchel et al., 2002) .  ...

Face masks reduce emotion-recognition accuracy and perceived closeness

Felix Grundmann, Kai Epstude, Susanne Scheibe
2021 PLoS ONE  
Exploratory analyses further revealed that face masks buffered the negative effect of negative (vs. non-negative) emotion expressions on perceptions of trustworthiness, likability, and closeness.  ...  Our preregistered study with 191 German adults revealed that face masks diminish people's ability to accurately categorize an emotion expression and make target persons appear less close.  ...  For instance, different brain areas are activated in men and women when processing emotional material [e.g., 21, 22] . Such differences in brain activation are thought to affect emotion recognition.  ...
