We conducted the largest multiple-iteration retelling study to date (12,840 participants and 19,086 retellings) with two different studies that test how emotional appraisals are transmitted across retellings. We use a novel Bayesian model that tracks changes across retellings. Study 1 examines the preservation of appraisals of happy and sad stories and finds that retellings preserve the story’s degree of happiness and sadness even when length shrinks and aspects of story coherence and rationalisation deteriorate. Study 2 compared the transmission of appraisals (...) of happiness and sadness with embarrassment, disgust, and risk. Appraisals of happiness, sadness, and also embarrassment showed high appraisal preservation, while disgust and risk were not well preserved. We conclude that participants in our studies encoded happy and sad stories by encapsulating the events and details into an overall emotional appraisal of the story and that this processing strategy might also apply to stories involving other emotions like embarrassment. The emotional appraisal played a key role in retelling by helping to guide the selection, invention, and ordering of the story elements. Hence, we posit that emotion appraisals can operate as anchors for remembering and retelling stories, thus playing an important role in narrative communication. (shrink)

Emotion is critical for cultural dynamics, that is, for the formation, maintenance, and transformation of culture over time. We outline the component micro- and macro-level processes of cultural dynamics, and argue that emotion not only facilitates the transmission and retention of cultural information, but also is shaped and crafted by cultural dynamics. Central to this argument is our understanding of emotion as a complete information package that signals the adaptive significance of the information that the agent is processing. It captures (...) an agent’s appraisal about the relationship between themself and the object of emotional focus, as well as action orientation and allostasis in context. We discuss implications of this perspective in the context of the changing natural and geopolitical environment, and future cultural dynamics into the 21st century. (shrink)

In recent debates in moral psychology and literary Darwinism, several authors suggested that narrative art plays a significant role in the process of the social learning of moral norms, functioning as storage of locally salient moral information. However, an integrative view, which would help explain the inner workings of this morally educative function of narrative art, is still lacking. This paper provides such a unifying theoretical account by bringing together insights from moral psychology, educational sciences, cognitive/evolutionary narratology, and cultural evolution. (...) A study of contemporary American rap music is included to showcase the benefits of this integrative approach in the context of one particular type of narrative art. (shrink)

Emotions signal flaws in the person’s anticipation systems, or in other words, in aspects of models of how the world works. As these models are essentially shared in society, emotional challenges e...

ABSTRACTThe presence of emotional words and content in stories has been shown to enhance a story’s memorability, and its cultural success. Yet, recent cultural trends run in the opposite direction. Using the Google Books corpus, coupled with two metadata-rich corpora of Anglophone fiction books, we show a decrease in emotionality in English-speaking literature starting plausibly in the nineteenth century. We show that this decrease cannot be explained by changes unrelated to emotionality, and that, in our three corpora, the decrease is (...) driven almost entirely by a decline in the proportion of positive emotion-related words, while the frequency of negative emotion-related words shows little if any decline. Consistently with previous studies, we also find a link between ageing and negative emotionality at the individual level. (shrink)

Cultural evolution researchers use transmission chain experiments to investigate which content is more likely to survive when transmitted from one individual to another. These experiments resemble oral storytelling, wherein individuals need to understand, memorize, and reproduce the content. However, prominent contemporary forms of cultural transmission—think an online sharing—only involve the willingness to transmit the content. Here I present two fully preregistered online experiments that explicitly investigated the differences between these two modalities of transmission. The first experiment (_N_ = 1,080 participants) (...) examined whether negative content, information eliciting disgust, and threat-related information were better transmitted than their neutral counterpart in a traditional transmission chain setup. The second experiment (_N_ = 1,200 participants) used the same material, but participants were asked whether or not they would share the content in two conditions: in a large anonymous social network or with their friends, in their favorite social network. Negative content was both better transmitted in transmission chain experiments and shared more than its neutral counterpart. Threat-related information was successful in transmission chain experiments but not when sharing, and finally, information eliciting disgust was not advantaged in either. Overall, the results present a composite picture, suggesting that the interactions between the specific content and the medium of transmission are important and, possibly, that content biases are stronger when memorization and reproduction are involved in the transmission—as in oral transmission—than when they are not—as in online sharing. Negative content seems to be reliably favored in both modalities of transmission. (shrink)

We experimentally investigated the influence of context-based biases, such as prestige and popularity, on the preferences for quotations. Participants were presented with random quotes associated to famous or unknown authors, or with random quotes presented as popular, i.e. chosen by many previous participants, or unpopular. To exclude effects related to the content of the quotations, all participants were subsequently presented with the same quotations, again associated to famous and unknown authors, or presented as popular or unpopular. Overall, our results showed (...) that context-based biases had no, or limited, effect in determining participants’ choices. Quotations preferred for their content were preferred in general, despite the contextual cues to which they were associated. We conclude discussing how our results fit with the well-known phenomenon of the spread and success of misattributed quotations, and we draw some more general implications for cultural evolution research.
