Who in the world is trying to change their personality traits? Volitional personality change among college students in six continents.

Recent research conducted largely in the United States suggests that most people would like to change one or more of their personality traits. Yet almost no research has investigated the degree to which and in what ways volitional personality change (VPC), or individuals' active efforts toward personality change, might be common around the world. Through a custom-built website, 13,278 college student participants from 55 countries and one of a larger country (Hong Kong, S.

To which world regions does the valence-dominance model of social perception apply?

Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions.

Happiness around the world: A combined etic-emic approach across 63 countries.

What does it mean to be happy? The vast majority of cross-cultural studies on happiness have employed a Western-origin, or "WEIRD" measure of happiness that conceptualizes it as a self-centered (or "independent"), high-arousal emotion. However, research from Eastern cultures, particularly Japan, conceptualizes happiness as including an interpersonal aspect emphasizing harmony and connectedness to others. Following a combined emic-etic approach (Cheung, van de Vijver & Leong, 2011), we assessed the cross-cultural applicability of a measure of independent happiness developed in the US (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999) and a measure of interdependent happiness developed in Japan (Interdependent Happiness Scale; Hitokoto & Uchida, 2015), with data from 63 countries representing 7 sociocultural regions.

International optimism: Correlates and consequences of dispositional optimism across 61 countries.

Objective: The current exploratory study sought to examine dispositional optimism, or the general expectation for positive outcomes, around the world.

Method: Dispositional optimism and possible correlates were assessed across 61 countries (N = 15,185; mean age = 21.92; 77% female).

Situational experience around the world: A replication and extension in 62 countries.

Objective: The current study seeks to replicate and extend principal findings reported in The World at 7:00, a project that examined the psychological experience of situations in 20 countries.

Method: Data were collected from participants in 62 countries (N = 15,318), recruited from universities by local collaborators to complete the study via a custom-built website using 42 languages.

Results: Several findings of the previous study were replicated.

The Psychological Science Accelerator: Advancing Psychology through a Distributed Collaborative Network.

Concerns have been growing about the veracity of psychological research. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution to these and other current methodological challenges.
