Dynamic Shielding and Allosteric Modulation of Erythropoietin by Glycosylation Open
Glycosylation is a ubiquitous and essential post-translational modification that regulates protein structure, solubility, and function. Yet, the mechanisms by which glycans modulate the physicochemical properties of protein surfaces remain…

Americans weigh an attended emotion more than Koreans in overall mood judgments Open
Face ensemble coding is the perceptual ability to create a quick and overall impression of a group of faces, triggering social and behavioral motivations towards other people (approaching friendly people or avoiding an angry mob). Cultural…

The effect of masks on the emotion perception of a facial crowd Open
The present study investigated the effect of facial masks on people’s ability to perceive emotions in crowds. We presented faces with the bottom halves occluded by masks or full faces without occlusion. In two sequentially presented crowds…

Neural bases of attentional contexts that mediate visuomotor adaptation Open
Visuomotor adaptation is essential to learning to recalibrate movements when environmental conditions change. Previous work showed that learning to counteract an abrupt perturbation under a single- or dual-task setting (i.e., attentional c…

Developmental characteristics of visuomotor adaptation strategies in childhood Open
Visual-motor integration is an essential skill in children’s development for acquiring new movements in dynamic environments. This requires visuomotor adaptation, in which motor commands are adjusted in response to visual feedback. Previou…

Evaluation of motion perception and binocular vision following dichoptic treatment for amblyopia Open
Poor monocular visual acuity and binocular vision, including stereopsis, are characteristic of amblyopia. Motion perception is also often disrupted in both amblyopic and fellow eyes. Occlusion therapy is the gold-standard treatment for amb…

Attentional context-dependent memory during gradual visuomotor adaptation Open
We recently demonstrated that the success of motor memory retrieval depends on whether participants consistently performed a secondary task during visuomotor adaptation and later recall, which was independent of available attentional resou…

Different responses of the scene-selective cortical regions to magnocellular- and parvocellular-biased visual information Open
Scene perception relies on a set of cortical regions, such as the parahippocampal place area (PPA), retrosplenial complex (RSC), and occipital place area (OPA), exhibiting dissociable functional selectivity to various scene properties. Deb…

Differential encoding of dynamic objects in navigational context Open
A fundamental challenge in the visual system is that objects and boundaries within a scene are all but stationary. For example, dynamic displacements of potential obstacles across time could either render a previous path unnavigable or pro…

An explicit investigation of the roles that feature distributions play in rapid visual categorization Open
Ensemble representations are often described as efficient tools when summarizing features of multiple similar objects as a group. However, it can sometimes be more useful not to compute a single summary description for all of the objects i…

Fast saccadic and manual responses to faces presented to the koniocellular visual pathway Open
The parallel pathways of the human visual system differ in their tuning to luminance, color, and spatial frequency. These attunements recently have been shown to propagate to differential processing of higher-order stimuli, facial threat c…

Magnocellular and parvocellular pathway contributions to facial threat cue processing Open
Human faces evolved to signal emotions, with their meaning contextualized by eye gaze. For instance, a fearful expression paired with averted gaze clearly signals both presence of threat and its probable location. Conversely, direct gaze p…

The effects of aging in neural processing of facial threat cues via magnocellular and parvocellular pathways. Open
During face perception, we integrate facial expression and eye gaze to make social inferences from their combined signals. For example, a fearful face and averted eye gaze are both avoidance cues which indicate threat presence and its prob…

<span>S</span> ex‐related differences in behavioral and amygdalar responses to compound facial threat cues Open
During face perception, we integrate facial expression and eye gaze to take advantage of their shared signals. For example, fear with averted gaze provides a congruent avoidance cue, signaling both threat presence and its location, whereas…

Introduction: The visual system exploits redundancies by extracting summary statistics from groups of similar items. In social situations, extracting average emotion from crowds of faces helps us to avoid potential threats (e.g., mob viole…

Neurodynamics and hemispheric lateralization in threat and ambiguous negative scene recognition Open
Efficient threat detection and appropriate action are critical for survival. However, some stimuli are merely negative without an impending threat and may offer useful clues about past or future dangers. We have shown previously (Kveraga e…

Differential visual pathway contributions to compound facial threat cue processing Open
Facial expression can be a threat cue whose meaning depends on the direction of eye gaze. For example, fear combined with averted eye gaze clearly signals threat and its location, while a direct gaze leaves the location ambiguous (Adams et…

Trait anxiety moderates visual pathway contributions to the processing of clear versus ambiguous threat. Open
Introduction: Fear expressions combined with averted gaze clearly signal where threat resides. Fear expressions coupled with direct gaze, however, are more ambiguous. Supporting this contention, Adams and Kleck (2003) found that direct gaz…
