Despite its prominence in third-wave cognitive-behavioral therapies (Hofmann and Asmundson 2008) such as Acceptance and …

    Open Access•Izabela Kaźmierczak, Anna Zajenkowska et al.•ARTICLE•Current Psychology•2024

    Dreams serve as a psychological space where the human mind grapples with burdensome issues, and war undoubtedly falls into that category. Inspired by Charlotte Beradt’s work on analyzing dreams during the Third Reich, we collected dreams from a sample of Polish individuals (N = 90) during the outbreak of war in March 2022. Our objective was to identify the most intense emotions conveyed through these dreams and investigate differences in both emo…

  • What do females really dream of? An individual-differences perspective on determining how narrative identity affects types of life projects and the ways of telling them

The study revealed the broad spectrum of LPs, with the most common categories related to study and work, regardless of the narrative identity incorporated into the study. However, separately taken, motives of agency and…

    Researchers have extensively explored the early and middle stages of romantic and sexual relationships for those high on the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) but they have generally missed the termination stage of relationships. In this study we examined (N = 341) the role these traits play in one termination strategy, ghosting. Ghosting is when a person discontinues a relationship through silence; it is con…
