Eye contact with another person (social gaze) can evoke emotions, produce autonomic arousal, and influence behavior. Gaze cues can be evocative even when presented in static pictures of faces suggesting that responses depend on low-level visual features of gaze stimuli. The current study examined whether emotional gaze responses depend on the physical stimulus properties of an eye contact experience versus the cognitive evaluation of the social context of gaze. This was done by comparing skin conductance responses (SCR), an index of emotional arousal, during episodes of social gaze and 'self-gaze' (gazing at one's own eyes in a mirror), keeping other aspects of the viewing conditions constant. We compared SCRs during social gaze and self-gaze in forty participant pairs. Each participant engaged in ten, 20 second eye contact trials, alternating between social and self-gaze. Self-gaze episodes produced significant SCRs but social gaze SCR's were larger and occurred more reliably. SCRs decreased across trials (habituation effect) in both conditions. We speculated that social gaze between opposite sex partners might yield larger SCRs but this was not found. Overall, these results conceptually replicate previous findings of (likely top-town) cognitive regulation of autonomic gaze responses based on evaluation of the social context.

EXPRESS: Activation of the Motor System Following Gaze Cues is Determined by Hand Access, Not Hand Proximity.

The influence of gaze cues on target prioritization (reaction times (RTs)) and movement execution (movement trajectories) differs based on the ability of the human gaze cue model to manually interact with the targets. Whereas gaze cues consistently impacted RTs, movement trajectories may only be affected when the hands of the human model had the potential to interact with the target. However, the perceived ability to interact with the targets was confounded by the proximity between the model's hands and the targets.

Introduction: Children with neurodevelopmental disabilities (NDs) display several developmental impairments across various domains that impact parent-child interactions, emphasizing the need for effective early interventions. This multi-centric study aimed to evaluate the impact of video-feedback intervention (VFI) on enhancing maternal behavior (i.e.

Through the lens of Guruprasad Kaginele's novel , the issues of intolerance and distrust that exist in American rural hospitals-where the Indian immigrant doctors fail to understand the inhibitions and apprehensions of the African immigrant birthing mothers, turning them into objects of mockery and disgust, despite sharing colonial histories of racialised discrimination, biases and prejudices-are examined. The ruptured relationship between Indian immigrant doctors and Sanghaali Muslim immigrant birthing mothers dramatised in the novel provides an insight into how Indian immigrant doctors' psyche is unconsciously imbued with medical coloniality, which has not received much scholarly attention. Drawing on critical approaches such as various orders of gaze-male, medical, colonial and imperial-and the concept of intersectionality, the hybrid subjectivities of the Indian immigrant doctors, ruptured doctor-patient relationship, and non-agentic status of the immigrant birthing mothers as represented in the novel are analysed.

Background: Social communication is a crucial factor influencing human social life. Quantifying the degree of difficulty faced in social communication is necessary for understanding developmental and neurological disorders and for creating systems used in automatic symptom screening and assistive methods such as social skills training (SST). SST by a human trainer is a well-established method.
