Emotional contagion Dotaz Zobrazit nápovědu
Collective gatherings are often associated with the alignment of psychophysiological states between members of a crowd. While the process of emotional contagion has been studied extensively in dyads as well as at the population level, our understanding of its operation and dynamics as they unfold in real time in real-world group contexts remains limited. Employing a naturalistic design, we investigated emotional contagion in a public religious ritual by examining the relationship between interpersonal distance and autonomic arousal. We found that proximity in space was associated with heightened affective synchrony between participants in the context of the emotionally laden ritual (a Hindu procession) compared with an unstructured walk along the same route performed by the same group. Our findings contribute to the understanding of collective emotions and their underlying psychophysiological mechanisms, emphasizing the role of cultural practices in shaping collective emotional experiences.

This study tested whether emotional contagion occurs when piglets directly observe a penmate in distress (restraint) and whether there is an effect of previous experience on the response to subsequent restraint or exposure to conspecific distress. Piglets (49.7 ± 0.7 days) were exposed in pairs to two stress phases (SP1 and SP2) in an arena divided into two pens by a wire mesh wall. During SP1, one of the pigs of a pair was either restrained (Stress treatment) or sham-restrained (Control treatment), while the other pig was considered observer. During SP2, the previous observer was restrained, while its penmate took the observer role. Heart rate variability, locomotion, vocalizations, body/head/ear and tail postures were monitored. During SP1, observer pigs responded to conspecific distress with increased indicators of attention (looking at, proximity to and snout contacts with the distressed pigs) and increased indicators of fear (reduced locomotion, increased freezing). During SP2, the observer pigs that had been restrained previously reacted more strongly (through higher proximity, decreased locomotion, increased freezing) to observing the penmate in restraint than pigs without the previous negative experience. This study suggests that young pigs are susceptible to emotional contagion and that this contagion is potentiated by previous exposure to the same stressor. These findings have implications for pig welfare in practical animal husbandry systems.

Touretteův syndrom (TS) je jednou z nejčastějších neuropsychiatrických poruch dětského věku. Obvyklý věk vzniku příznaků je mezi 5. a 6. rokem věku a naprostá většina případů vznikne do 12 let, až čtyřikrát častěji u chlapců než u dívek. Průběh onemocnění je charakteristicky měnlivý v čase, s exacerbacemi, remisemi a změnami rázu tiků. V dospívání se obvykle tiky zmírňují a výrazné pozdní exacerbace se vyskytují zřídka. Od roku 2020 však prudce vzrostl počet nově vzniklých případů tikové poruchy u adolescentních dívek. Jejich projevy jsou inkongruentní s klasickým obrazem TS a svědčí pro funkční (psychogenní) původ, přičemž vykazují nápadně shodné rysy s videozáznamy šířenými na sociálních sítích. Na případech několika našich pacientek ukazujeme typické projevy onemocnění. Uvádíme koncept masové sociogenní nemoci, popisujeme roli sociálních médií při jejím šíření a uvádíme paralely s historickými hromadnými psychickými jevy.
Tourette syndrome (TS) is one of the most common neuropsychiatric disorders of childhood. The usual age of symptom onset is between the ages of 5 and 6 years, and the vast majority of cases emerge by age 12, up to four times more often in boys than in girls. The course of the disease characteristically varies over time, with exacerbations, remissions, and changes in the tic pattern. In adolescence, the tics usually diminish and marked late exacerbations are rare. However, since 2020, the number of new cases of tic disorder has increased sharply in adolescent girls. Their manifestations are incongruent with the classical presentation of TS and are suggestive of a functional (psychogenic) origin. They show strikingly similar features to videos circulated on social media. We present the typical manifestations of the disease in several of our patients. Using the concept of mass sociogenic illness, we describe the role of social media in its spread and draw parallels with historical mass psychiatric phenomena.
