Some scholars observed a “nostalgia bump” during the COVID-19 pandemic, where people compensated for social isolation by engaging with products and experiences evoking nostalgia. To further explore this effect and its underlying mechanism, the authors tested the hypothesis that reduced social contact during lockdown conditions would lead people to feel lonely and bored and, in turn, increase their consumption of nostalgic music. Study 1 ( Nsong = 213,464) established the temporal relationships between social contact and nostalgia by analyzing mobility data and daily listening patterns of top songs on the music platform Spotify from 2019 to 2021. Study 2 ( N = 525) was a retrospective survey of individual experiences during the lockdown period. Results showed that reduced social contact had an indirect positive effect on consumption of nostalgic songs through loneliness, but not boredom. These findings shed light on the use of nostalgia as a coping strategy during times of isolation.

Both researchers and practitioners have stressed the importance of developing rapport in the investigative interviewing of criminal suspects. There is, however, no clear definition of what constitutes rapport and ways of achieving and maintaining rapport. Most research on rapport building with suspects have focused on a positive personal bond between the investigator and suspect (i.e., relationship-based approach), while more recent research suggests the merits of a neutral type of rapport building that focuses on developing a mutual understanding of the interrogation process and roles (i.e., procedure-based approach). The present study thus aimed to examine the effects of relationship-and procedure-based rapport building approaches on suspect interviewing outcome. Using a modified version of Russano, Meissner, Narchet, and Kassin's (2005) cheating paradigm, "guilty" participants were interviewed using different rapport building approaches in a laboratory setting. We found that participants were more likely to confess in the procedure-based condition than in the relationship-based and control conditions. However, both approaches did not have an effect on the number of details participants were willing to disclose. We also found that the procedure-based approach affected participants' perception about the evidence. Theoretical and practical implications for rapport building in suspect interviewing are discussed.
