Only healthy participants are included in the study. The study aims to examine whether participants’ perception of stimuli can be influenced by the type of pantomime task they perform prior to the main experiment—specifically, whether they engage in socially interactive pantomime tasks with the experimenter or perform solo pantomime tasks. We hypothesize that activating the social brain through interactive pantomime increases the tendency to mistakenly rely on social cues, leading to a higher nu
Conditions
Interventions
Group 1: Verum- group:
Before the Bayesian Ghost paradigm, participants perform socially interactive pantomime tasks (five different tasks, each repeated four times
total duration approximately 20 minutes).
Group 2: control group:
Before the Bayesian Ghost paradigm, participants perform solo pantomime tasks (five different tasks, each repeated four times
total duration approximately 20 minutes).

18 Years to 65 Years
Inclusion criteria
Inclusion criteria: Sufficient knowledge of German (since the normative values of the psychometric tests are based on German-speaking participants, including participants with insufficient German skills would lead to a relevant distortion of the results; moreover, the informed consent documents are only available in German, and the experimenters have only sufficient German language proficiency)
Exclusion criteria
Exclusion criteria: - History of regular (>5 days per week) and heavy alcohol consumption (>60 g alcohol/day) - History of cannabis, cocaine, amphetamine, heroin, or other substance use (excluding nicotine) within the past month - Insufficient knowledge of the German language (see above) - current psychiatric disorders, except for nicotine dependence - Neurological disorders of the central nervous system - Verbal IQ below 70
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Bayesian Ghost error: Calculated as the difference between the number of false alarms in the communicative condition (Arm 1) and the non-communicative condition (Arm 2). A comparison is then made between the two groups: communicative pantomime vs. solo pantomime. | — |
Secondary
| Measure | Time frame |
|---|---|
| Association between the synchronization of movement between the experimenter and the participant during the preliminary task and the Bayesian Ghost error, including group affiliation (see primary endpoint) as a covariate. | — |
