Visual awareness and the detection of fearful faces

by Luiz Pessoa, Shruti Japee, Leslie G. Ungerleider - Emotion , 2005
"... A commonly held view is that emotional stimuli are processed independently of awareness. Here, the authors parametrically varied the duration of a fearful face target stimulus that was backward masked by a neutral face. The authors evaluated awareness by characterizing behavioral performance using r ..."

Cultural specificity in amygdala response to fear faces

by Joan Y. Chiao, Tetsuya Iidaka, Heather L. Gordon, Junpei Nogawa, Moshe Bar, Elissa Aminoff, Norihiro Sadato, Nalini Ambady - J. Cogn. Neurosci , 2008
"... & The human amygdala robustly activates to fear faces. Heightened response to fear faces is thought to reflect the amygdala’s adaptive function as an early warning mechanism. Although culture shapes several facets of emotional and social experience, including how fear is perceived and expressed ..."

ERPs reveal subliminal processing of fearful faces

by Monika Kiss, Martin Eimer - Psychophysiology , 2008
"... To investigate whether facial expression is processed in the absence of conscious awareness, ERPs were recorded in a task in which participants had to identify the expression of masked fearful and neutral target faces. On supraliminal trials (200 ms target duration), in which identification performa ..."

Electrophysiological correlates of rapid spatial orienting towards fearful faces

by Gilles Pourtois, Didier Gr, David S, Patrik Vuilleumier - Cereb. Cortex , 2004
"... We investigated the spatio-temporal dynamic of attentional bias towards fearful faces. Twelve participants performed a covert spatial orienting task while recording visual event-related brain potentials (VEPs). Each trial consisted of a pair of faces (one emotional and one neutral) briefly presented ..."

Individual Differences in Detecting Rapidly Presented Fearful Faces

by An Zhang, Lili Wang, Yi Luo, Yuejia Luo , 2012
"... Rapid detection of evolutionarily relevant threats (e.g., fearful faces) is important for human survival. The ability to rapidly detect fearful faces exhibits high variability across individuals. The present study aimed to investigate the relationship between behavioral detection ability and brain a ..."

Effects of Unconscious Processing on Implicit Memory for Fearful Faces

by Jiongjiong Yang, Xiaohong Xu, Xiaoya Du, Cuntong Shi, Fang Fang
"... Emotional stimuli can be processed even when participants perceive them without conscious awareness, but the extent to which unconsciously processed emotional stimuli influence implicit memory after short and long delays is not fully understood. We addressed this issue by measuring a subliminal affe ..."

affective priming effect in Experiment 1 and a long-term priming effect in Experiment 2. In Experiment 1, a flashed fearful or neutral face masked by a scrambled face was presented three times, then a target face (either fearful or neutral) was presented and participants were asked to make a fearful

Target visibility and visual awareness modulate amygdala responses to fearful faces

by Luiz Pessoa, Shruti Japee, David Sturman, Leslie G. Ungerleider - Cerebral Cortex , 2006
"... The goals of the present study were twofold. First, we wished to investigate the neural correlates of aware and unaware emotional face perception after characterizing each subject’s behavioral performance via signal detection theory methods. Second, we wished to investigate the extent to which amygd ..."
Abstract - Cited by 54 (2 self) - Add to MetaCart
amygdala responses to fearful faces depend on the physical characteristics of the stimulus independently of the percept. We show that amygdala responses depend on visual awareness. Under conditions in which subjects were not aware of fearful faces flashed for 33 ms, no differential activation was observed

Spatial Attention Effects of Disgusted and Fearful Faces

by An Zhang, Yunzhe Liu, Chenglin Zhou, Yuming Chen, Yuejia Luo
"... Effective processing of threat-related stimuli is of significant evolutionary advantage. Given the intricate relationship between attention and the neural processing of threat-related emotions, this study manipulated attention allocation and emotional categories of threat-related stimuli as independ ..."

as independent factors and investigated the time course of spatial-attention-modulated processing of disgusting and fearful stimuli. The participants were instructed to direct their attention either to the two vertical or to the two horizontal locations, where two faces and two houses would be presented

BREVIA Effects of Gaze on Amygdala Sensitivity to Anger and Fear Faces

by Reginald B. Adams, Heather L. Gordon, Abigail A. Baird, Nalini Ambady, Robert E. Kleck
"... The amygdala is thought to be part of a neural system responsive to potential threat (1). Consistent with this is the amygdala’s well-documented sensitivity to fear faces. What is puzzling, however, is the paucity of evidence for a similar involvement of the amygdala in the processing of anger displ ..."

Cardiac Vagal Tone Predicts Attentional Engagement To and Disengagement From Fearful Faces

by Gewnhi Park, Jay J. Van Bavel, Michael W. Vasey, Julian F. Thayer, Van Bavel
"... The current research examines individual differences in flexible emotional attention. In two experiments, we investigated the relationship between individual differences in cardiac vagal tone and top-down and bottom-up processes associated with emotional attention. To help determine the role of cort ..."

of cortical and subcortical mechanisms underlying top-down and bottom-up emotional attention, fearful faces at broad, high, and low spatial frequency were presented as cues that triggered either exogenous or endogenous orienting. Participants with lower heart rate variability (HRV) exhibited faster
