Is emotion perception altered by gaze direction, gender appearance, and gender identity of the perceived face?

The purpose of the present study was to examine how gaze and emotion processing may change due to differences in gender appearance and gender identity of the perceived face. We manipulated gender appearance (male or female), gender identity (cisgender or transgender), gaze direction (direct or averted), and expressed emotions (anger, fear, or neutral) of face models in an emotion rating task. We replicate several previous findings, including a direct gaze advantage, an emotion effect, and an interaction between gaze direction and expressed emotion.

Don't look at me like that: Integration of gaze direction and facial expression.

Efficient decoding of facial expressions and gaze direction supports reactions to social environments. Although both cues are processed fast and accurately, when and how these cues are integrated is still debated. We investigated the temporal integration of gaze and emotion cues.

What's in a gaze, what's in a face?: The direct gaze effect can be modulated by emotion expression.

Gaze direction and emotion expression are salient facial features that facilitate social interactions. Previous studies addressed how gaze direction influences the evaluation and recognition of emotion expressions, but few have tested how emotion expression influences attentional processing of direct versus averted gaze faces. The present study examined whether the prioritization of direct gaze (toward the observer) relative to averted gaze (away from the observer) is modulated by the emotional expression of the observed face.

Understanding joint action: Current theoretical and empirical approaches.

Joint actions are omnipresent, ranging from a handshake between two people to the coordination of groups of people playing in an orchestra. We are highly skilled at coordinating our actions with those of others to reach common goals and rely on this ability throughout our daily lives. What are the social, cognitive and neural processes underlying this ability? How do others around us influence our task representations? How does joint action influence interpersonal interactions? How do language and gesture support joint action? What differentiates joint action from individual action? This article forms an introductory editorial to the field of joint action.

Impaired Motor Recycling during Action Selection in Parkinson's Disease.

Behavioral studies have shown that the human motor system recycles motor parameters of previous actions, such as movement amplitude, when programming new actions. Shifting motor plans toward a new action forms a particularly severe problem for patients with Parkinson's disease (PD), a disorder that, in its early stage, is dominated by basal ganglia dysfunction. Here, we test whether this action selection deficit in Parkinson's patients arises from an impaired ability to recycle motor parameters shared across subsequent actions.

Planning my actions to accommodate yours: joint action development during early childhood.

The planning and adjusting of one's actions in relation to an action partner is fundamental to smooth joint action. During their first years of life, children gradually become more engaged in joint actions. Here, we investigated whether and at what age children take their partner into account in their action plans to accommodate the other's actions.

Eyes only? Perceiving eye contact is neither sufficient nor necessary for attentional capture by face direction.

Direct eye contact and motion onset both constitute powerful cues that capture attention. Recent research suggests that (social) gaze and (non-social) motion onset influence information processing in parallel, even when combined as sudden onset direct gaze cues (i.e.

Entrainment and task co-representation effects for discrete and continuous action sequences.

A large body of work has established an influence of other people's actions on our own actions. For example, actors entrain to the movements of others, in studies that typically employ continuous movements. Likewise, studies on co-representation have shown that people automatically co-represent a co-actor's task, in studies that typically employ discrete actions.

Me and we: Metacognition and performance evaluation of joint actions.

Recent evidence suggests the existence of we-mode processing, but little is still known about how such processing influences the sense of control during intentional joint actions. To examine this issue, dyads performed a video game in which they moved a dot to the target of their choice out of a set of targets. By having each participant control the dot movements in only one dimension (orthogonal to their partner) and by varying the target locations, participants took on different roles.

Catching eyes: effects of social and nonsocial cues on attention capture.

Direct eye contact and motion onset are two powerful cues that capture attention. In the present study, we combined direct gaze with the sudden onset of motion to determine whether these cues have independent or shared influences. Participants identified targets presented randomly on one of four faces.

Do people automatically track others' beliefs? Evidence from a continuous measure.

Recent findings suggest that tracking others' beliefs is not always effortful and slow, but may rely on a fast and implicit system. An untested prediction of the automatic belief tracking account is that own and others' beliefs should be activated in parallel. We tested this prediction measuring continuous movement trajectories in a task that required deciding between two possible object locations.

Higher-order action planning for individual and joint object manipulations.

Many actions involve multiple action steps, which raises the question how far ahead people plan when they perform such actions. Here, we examined higher-order planning for action sequences and whether people planned similarly or differently when acting individually or together with an action partner. For individual performances, participants picked up an object with one hand and passed it to their other hand before placing it onto a target location.

Are you ready to jump? Predictive mechanisms in interpersonal coordination.

When two or more individuals intend to achieve a joint outcome, they often need to time their own actions carefully with respect to those of their coactors. Online perceptual feedback supports coordination by allowing coactors to entrain with and predict each other's actions. However, joint actions are still possible when no or little online feedback is available.

The sense of agency during skill learning in individuals and dyads.

The sense of agency has received much attention in the context of individual action but not in the context of joint action. We investigated how the sense of agency developed during individual and dyadic performance while people learned a haptic coordination task. The sense of agency increased with better performance in all groups.

Making oneself predictable: reduced temporal variability facilitates joint action coordination.

Performing joint actions often requires precise temporal coordination of individual actions. The present study investigated how people coordinate their actions at discrete points in time when continuous or rhythmic information about others' actions is not available. In particular, we tested the hypothesis that making oneself predictable is used as a coordination strategy.

Let the force be with us: dyads exploit haptic coupling for coordination.

People often perform actions that involve a direct physical coupling with another person, such as when moving furniture together. Here, we examined how people successfully coordinate such actions with others. We tested the hypothesis that dyads amplify their forces to create haptic information to coordinate.

Bimanual grasp planning reflects changing rather than fixed constraint dominance.

We studied whether motor-control constraints for grasping objects that are moved to new positions reflect a rigid constraint hierarchy or a flexible constraint hierarchy. In two experiments, we asked participants to move two plungers from the same start locations to different target locations (both high, both low, or one high and one low). We found that participants grasped the plungers symmetrically and at heights that ensured comfortable or easy-to-control end postures when the plungers had the same target heights, but these grasp tendencies were reduced when the plungers had different target heights.

Moving the arm at different rates: slow movements are avoided.

Qualitative and quantitative changes characterize locomotion and rhythmic interlimb coordination at different speeds. Legs and hands do not move more or less quickly; they also adopt different relative coordination patterns. In the present article, the authors asked whether similar transitions occur for unimanual hand movements when speed is slowed below the preferred speed.

Hand path priming in manual obstacle avoidance: evidence for abstract spatiotemporal forms in human motor control.

Previous research suggests that motor equivalence is achieved through reliance on effector-independent spatiotemporal forms. Here the authors report a series of experiments investigating the role of such forms in the production of movement sequences. Participants were asked to complete series of arm movements in time with a metronome and, on some trials, with an obstacle between 1 or more of the target pairs.

Coordination of locomotion and prehension.

Although locomotion and prehension are commonly coordinated in everyday life, little previous research has focused on this form of coordination. To address this neglected topic, we asked participants to stand a variable distance from a table, walk up to the table, and move an object on the tabletop to a new tabletop position, either to the right or to the left of the object's initial position and near or far from that initial position. For large manual displacements, which required a step after picking up the object, subjects preferred to stand on the foot opposite the direction of forthcoming manual displacement.
