Research on social transmission suggests that people preferentially transmit information about threats and social interactions. Such biases might be driven by the arousal that is experienced as part of the emotional response triggered by information about threats or social relationships. The current studies tested whether preferences for transmitting threat-relevant information are consistent with a functional motive to recruit social support. USA residents were recruited for six online studies. Studies 1a and 1B showed that participants more often chose to transmit positive, (...) low-arousal vignettes. Studies 2A and 2B showed higher intentions to transmit emotional vignettes to friends. Study 4 showed a preference for transmitting stories that participants had modified and were therefore novel and unique. Studies 2A and 3 suggest that motivations for seeking social support might influence transmission preferences. Overall, the findings are not easily accounted for by any of the major theories of social transmission. We discuss limitations of the current studies and directions for further research. (shrink)

The spatial composition of human portraits obeys historically changing cultural norms. We show that it is also affected by cognitive factors that cause greater spontaneous attention to what is in front rather in the back of an agent. Scenes with more space in front of a directed object are both more often produced and judged as more aesthetically pleasant. This leads to the prediction that, in profile‐oriented human portraits, compositions with more space in front of depicted agents (a “forward bias”) (...) should be over‐represented. By analyzing a large dataset (total N of 1,831 paintings by 582 unique identified European painters from the 15th to the 20th century), we found evidence of this forward bias: Painters tended to put more free space in front of, rather than behind, the sitters. Additionally, we found evidence that this forward bias became stronger when cultural norms of spatial composition favoring centering became less stringent. (shrink)

The two target articles agree that processes of cultural evolution generate richness and diversity in music, but neither address this question in a focused way. We sketch one way to proceed – and hence suggest how the target articles differ not only in empirical claims, but also in their tacit, prior assumptions about the relationship between cognition and culture.
