“…According to Jaspers, the Doppelgdnger was not a unitary phenomenon, but rather one able to take on different forms: it could, for example, be part of a delusional or part of an hallucinatory type of heautoscopy and so on. This contrasts sharply with the formal concept of the Doppelgdnger recently defined by Maack & Muller (1983) for in Jasperian psychopathological terms their Doppelgdnger actually seems to be a combination of a disturbance of the awareness of the unity of the ^e//with an autoscopic hallucination.…”

SYNOPSISModern reports on lycanthropy mainly concentrate on the content of patients' beliefs in being transformed into an animal. By contrast, an interest in the form of the symptomatology is usually minimal. This paper draws on Karl Jaspers' phenomenological views and focuses on some important albeit neglected psychopathological issues related to form which are relevant to any comprehensive consideration of lycanthropic phenomena.

“…For instance, we excluded many previously reported cases, who were actually not AP (see also [11,21,31]), but non-visual body schema disturbances such as the convincing feeling that there is another person close by without actually seeing that person. This phenomenon has been called ''leibhafte Bewusstheit'' [56], ''hallucination du compagnon'' [62] or ''feeling of a presence'' [10,21] [51,57,68,71,72,79,91]). Accordingly, we also excluded cases of AP due to migraine, hysteria, narcolepsy, cataplexy, confuso-oniric states, or of hypnagogic origin as well as AP-cases of non-focal or generalized neurological origin ( [50, #78], [32, #3, #5, #7]).…”

Autoscopic phenomena (AP) are rare illusory visual experiences during which the subject has the impression of seeing a second own body in extrapersonal space. AP consist of out-of-body experience (OBE), autoscopic hallucination (AH), and heautoscopy (HAS). The present article reviews and statistically analyzes phenomenological, functional, and anatomical variables in AP of neurological origin (n = 41 patients) that have been described over the last 100 years. This was carried out in order to further our understanding of the underlying mechanisms of AP, much as previous research into the neural bases of body part illusions has demystified these latter phenomena. Several variables could be extracted, which distinguish between or are comparable for the three AP providing testable hypotheses for subsequent research. Importantly, we believe that the scientific demystification of AP may be useful for the investigation of the cognitive functions and brain regions that mediate processing of the corporeal awareness and self consciousness under normal conditions.

“…One might imagine, as we sketched in the introduction, that perceiving the avatar as actively mimicking the participant’s actions would make it necessarily related to the task, as opposed to, as in the static case, an accidental bystander. Consequently, a change in the mirror image could constitute a particularly disrupting, if not disturbing event: after all, such an imaginary change in self-perception is a classic motif in horror stories ( Dietrich, 1992 ) and a symptom in psychiatry ( Maack and Mullen, 1983 ). Whether frightful or merely task-relevant, the predicted effect of avatar changes should from this perspective be larger in animated than in static conditions.…”

The self in conflict: actors and agency in the mediated sequential Simon task

Executive control refers to the ability to withstand interference in order to achieve task goals. The effect of conflict adaptation describes that after experiencing interference, subsequent conflict effects are weaker. However, changes in the source of conflict have been found to disrupt conflict adaptation. Previous studies indicated that this specificity is determined by the degree to which one source causes episodic retrieval of a previous source. A virtual reality version of the Simon task was employed to investigate whether changes in a visual representation of the self would similarly affect conflict adaptation. Participants engaged in a mediated Simon task via 3D “avatar” models that either mirrored the participants’ movements, or were presented statically. A retrieval cue was implemented as the identity of the avatar: switching it from a male to a female avatar was expected to disrupt the conflict adaptation effect (CAE). The results show that only in static conditions did the CAE depend on the avatar identity, while in dynamic conditions, changes did not cause disruption. We also explored the effect of conflict and adaptation on the degree of movement made with the task-irrelevant hand and replicated the reaction time pattern. The findings add to earlier studies of source-specific conflict adaptation by showing that a visual representation of the self in action can provide a cue that determines episodic retrieval. Furthermore, the novel paradigm is made openly available to the scientific community and is described in its significance for studies of social cognition, cognitive psychology, and human–computer interaction.
