A primer on open-source, experimental social media simulation software: Opportunities for misinformation research and beyond.

Social media simulation software (SMSS) allows researchers to collect behavioural data on how participants to engage with researcher-specified social media content using natural, interactive social media user interfaces. A notable subset of SMSS allow for experimental observation of how people engage with different types of content or user interfaces. Providing an avenue for collecting causal evidence on how algorithmic recommendation systems and design affordances of social media platforms impact behaviour; particularly online harms like misinformation.

National identity predicts public health support during a global pandemic.

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g.

Skin tone surveillance, depression, and life satisfaction in Indian women: Colour-blind racial ideology as a moderator.

Consistent with objectification theory, many studies have shown that self-objectification (and body surveillance) is associated with depression and dissatisfaction with life. Critically, however, much of this research has been conducted with White women attending university in North America. To extend this literature, we investigated whether greater skin tone surveillance - a group-specific manifestation of self-objectification among women of colour - is linked to higher depression and lower life satisfaction among Indian women.

An eye for the I: Preferential attention to the eyes of ingroup members.

Human faces, and more specifically the eyes, play a crucial role in social and nonverbal communication because they signal valuable information about others. It is therefore surprising that few studies have investigated the impact of intergroup contexts and motivations on attention to the eyes of ingroup and outgroup members. Four experiments investigated differences in eye gaze to racial and novel ingroups using eye tracker technology.

The political (and physiological) divide: Political orientation, performance monitoring, and the anterior cingulate response.

Our goal was to test a model of sociopolitical attitudes that posits a relationship between individual differences in liberal versus conservative political orientation and differential levels of anterior cingulate cortex (ACC) responsivity. We recorded event-related potentials (ERPs) while participants who varied along a unidimensional liberal-conservative continuum engaged in a standard Go/NoGo task. We also measured component attitudes of political orientation in the form of traditionalism (degree of openness to social change) and egalitarianism (a preference for social equality).

Functional or fantasy? Examining the implications of subjective temporal perspective "trajectories" for life satisfaction.

In a 5-year longitudinal study of young community adults, the authors examined subjective temporal perspective (STP) "trajectories" derived from ratings of past, present, and anticipated future life satisfaction (LS) collected at two time points. Upward STP trajectories (past < present < future LS) were normative at both time points. Opposing hypotheses were derived from the literature concerning the potential positive versus negative implications of upward STP trajectories.

Autonomic and electrophysiological correlates of emotional intensity in older and younger adults.

Anterior cingulate cortex (ACC) is involved in the modulation of autonomic activity, emotional responsivity, and the monitoring of goal-directed behavior. However, these functions are rarely studied together to determine how they relate or whether their pattern of relation changes with age. We recorded respiratory sinus arrhythmia (RSA), an index of autonomic activity, error-related event related potentials (ERN/Pe), generated in ACC, and the self-reported intensity of 5 basic emotions in older and younger adults.
