MSIS was accompanied by a predictable rhythmic sound (e.g a metronome beat, sounds produced by participants’ drumming, a song) with experiments in which no sound accompanied the synchronous movementstimulation. Experimenter Effects It has been well established that the experimenter’s expectations can influence participants’ behavior even when theZeitschrift f Psychologie (206), 224(3), 68contact amongst PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/11836068 the experimenter and participant is scripted and minimal (Rosenthal Rubin, 978). Preliminary evidence has suggested that the effects of MSIS dissipate when controlling for this bias (Schachner Mehr, 205). Therefore, within this metaanalysis, we assume that the effect of MSIS on prosociality is larger in the presence of an unblinded experimenter. Other Methodological Qualities Finally, we investigated regardless of whether the design of the principal study (inside vs. involving), variety of synchrony (active movement, passive movement, sensory stimulation), and implementation of a manipulation verify (vs. lack thereof) moderate the effects of MSIS.ObjectivesBecause analysis on MSIS has been largely performed inside the form of single research, typically around the basis of compact and homogenous samples, the existing metaanalysis aims to synthesize the isolated and from time to time contradictory findings. To date, there have been no quantitative evaluations in the effect of MSIS on prosociality. Whereas synchronization to an external beat has been intensively studied (see Repp, 2006a, 2006b; Repp Su, 203 for any critique), only one qualitative systematic overview (Repp Su, 203) has examined the effects of interpersonal synchrony on social outcomes. Repp concluded that interpersonal synchrony yields constructive effects in terms of heightened prosociality; nevertheless, the size of those effects at the same time as prospective moderators remain unclear. Inside the present metaanalysis, we quantitatively assessed the social consequences of MSIS and systematically investigated possible moderators of this partnership like each moderators currently explored in principal analysis and extra moderators which might be complicated to manipulate in oneshot experiments.Investigation QuestionsThe metaanalysis at hand seeks to answer the following questions: RQa: Which social consequences does MSIS entail RQb: What is the size on the effects, if there are actually any effects RQ2: Which variables (if any) moderate the effects of MSIS on social 
outcomes RQ3: Does the effect of MSIS depend on the type of comparison group used206 Hogrefe Publishing. Distributed below the Hogrefe OpenMind License http:dx.doi.org0.027aM. Rennung A. S. G itz, Prosocial Consequences of Interpersonal SynchronyMethodsInclusion and Exclusion CriteriaTo be incorporated in the metaanalysis, studies needed to report at the very least one particular impact size or info to calculate an effect size of your effects of MSIS (as defined above) on social outcomes. We defined social outcomes as all reactions pertaining to other social entities involved within the synchronous or manage intervention, too as all variables measuring traits of social interactions among participants. Importantly, in this metaanalysis, social outcomes were limited to the folks straight away involved in the MSIS. We didn’t involve outcomes regarding social behaviorattitudes toward LY3039478 web individuals or groups not involved in the MSIS (e.g prosocial attitude in general). Furthermore, we integrated only research that applied an experimental style in which MSIS was compared with at least one manage group. Regarding.
