Language use on Twitter reflects social structure and social disparities.

Large-scale mental health assessments increasingly rely upon user-contributed social media data. It is widely known that mental health and well-being are affected by minority group membership and social disparity. But do these factors manifest in the language use of social media users? We elucidate this question using spatial lag regressions.

Text as signal. A tutorial with case studies focusing on social media (Twitter).

Sentiment analysis is the automated coding of emotions expressed in text. Sentiment analysis and other types of analyses focusing on the automatic coding of textual documents are increasingly popular in psychology and computer science. However, the potential of treating automatically coded text collected with regular sampling intervals as a signal is currently overlooked.

The Interactive Functions of Questions in Embodied Collaborative Work.

Researchers have been interested in the investigation of the interactive functions of questions in conversational contexts. However, limited research has been conducted on the interactive functions of questions in embodied collaborative work, that is, work that involves the manipulation of physical objects. This study aimed to identify the interactive functions of questions in embodied collaborative work.

Twitter, time and emotions.

The study of temporal trajectories of emotions shared in tweets has shown that both positive and negative emotions follow nonlinear circadian (24 h) and circaseptan (7-day) patterns. But to this point, such findings could be instrument-dependent as they rely exclusively on coding using the Linguistic Inquiry Word Count. Further, research has shown that self-referential content has higher relevance and meaning for individuals, compared with other types of content.

Cultural transmission in a food preparation task: The role of interactivity, innovation and storytelling.

Interactive conversation drives the transmission of cultural information in small groups and large networks. In formal (e.g.

Editors' Introduction: Remembering With Others: Conversational Dynamics and Mnemonic Outcomes.

Remembering the past through conversations with others is a uniquely human endeavor. Conversational remembering consists of specific dynamics and can lead to mnemonic outcomes. While conversational dynamics refer to the interactive processes (e.

Storytelling as Adaptive Collective Sensemaking.

Storytelling represents a key element in the creation and propagation of culture. Three main accounts of the adaptive function of storytelling include (a) manipulating the behavior of the audience to enhance the fitness of the narrator, (b) transmitting survival-relevant information while avoiding the costs involved in the first-hand acquisition of that information, and (c) maintaining social bonds or group-level cooperation. We assess the substantial evidence collected in experimental and ethnographic studies for each account.

Memory bias toward emotional information in burnout and depression.

A sample of 1015 educational staff members, exhibiting various levels of burnout and depressive symptoms, underwent a memory test involving incident encoding of positive and negative words and a free recall task. Burnout and depression were each found to be associated with increased recall of negative items and decreased recall of positive items. Results remained statistically significant when controlling for history of depressive disorders.
