Our work investigates the influence of self-related cues in the design of virtual humans on body perception in virtual reality. In a $2\times 2$ mixed design, 64 participants faced photorealistic virtual humans either as a motion-synchronized embodied avatar or as an autonomous moving agent, appearing subsequently with a personalized and generic texture. Our results unveil that self-related cues through embodiment and personalization yield an individual and complemented increase in participants' sense of embodiment and self-identification towards the virtual human. Different body weight modification and estimation tasks further showed an impact of both factors on participants' body weight perception. Additional analyses revealed that the participant's body mass index predicted body weight estimations in all conditions and that participants' self-esteem and body shape concerns correlated with different body weight perception results. Hence, we have demonstrated the occurrence of double standards through induced self-related cues in virtual human perception, especially through embodiment.

We preferentially process self-related information. However, less is known about how this advantage extends to reward processing and if this process is sensitive to a continuum of self-relevance. Specifically, do we dissociate ourselves from all others when processing rewards, or do those we know personally also enjoy self-related biases? To address this, we recorded electroencephalographic (EEG) data from 30 undergraduate student participants who played a simple two-choice "bandit" gambling game where a photo presented before each gamble indicated whether it benefited either the participant, an individual they knew, or a person they did not know.

Individuals with high social anxiety show a more considerable attentional bias toward self-relevant information and outwardly threatening stimuli than do those with low social anxiety. Some studies have investigated the attentional bias between self-relevant information and external social cues in people with high social anxiety but have not reached consistent conclusions. This study used a modified dot-probe task and collected temporal and electroencephalogram responses to three self-other face pairs among 15 people with high social anxiety and 20 people with low social anxiety.

In this article we present a review of research on the IAM Task, whereby memories are cued by self-images in the form of "I am … " statements, such as I am a grandfather, I am a Bob Dylan fan, I am from Darlington, I am a Psychologist. Such cues are particularly successful at accessing memories associated with the formation of specific aspects of the self. We describe the conceptual and historical context for the development of our task and review findings from other researchers who have used the same basic design.
