Open Access Peer-reviewed Research Article Vasileia Aristotelidou,  arianna Tsatali, Paul G. Overton, Ana B. Vivas Published: September 2, 2021 https://doi.org/10.1371/journal.pone.0256144 Abstract Introduction Parkinson’s disease (PD) is manifested along with non-motor symptoms such as impairments in basic emotion regulation, recognition and expression. Yet, self-conscious emotion (SCEs) such as self-disgust, guilt and shame are under-investigated. Our previous research indicated that Parkinson patients have elevated levels of self-reported and induced self-disgust. However, the cause of that elevation–whether lower level biophysiological factors, or higher…

The neural mechanisms mediating social status have become increasingly well understood in invertebrates and model organisms like fish and mice but until recently have remained more opaque in humans and…

Levine Published: April 15, 2021 https://doi.org/10.1371/journal.pone.0249815 Abstract Truth-Default Theory (TDT) predicts that across countries and cultures, a few people tell most of the lies, while a majority of people lie less frequently than average. This prediction, referred to as “a few prolific liars,” is tested in Japan. The study further investigated the extent to which the Dark Triad personality traits predict the frequency of lying. University students…

Open Access Peer-reviewed Research Article Joanna Lockwood , Ellen Townsend, Heather Allen, David Daley, Kapil Sayal Published: December 21, 2020 https://doi.org/10.1371/journal.pone.0244319 Abstract Youth who self-harm report high levels of trait impulsivity and identify impulsive behaviour as a proximal factor directly preceding a self-harm act. Yet, impulsivity is a multidimensional construct and distinct impulsivity-related facets relate differentially to self-harm outcomes. Studies have yet to examine if and how a multidimensional account of impulsivity is meaningful to individual experiences and understandings of…

Zumbusch, Kristin M. von Ranson Published: February 15, 2018 https://doi.org/10.1371/journal.pone.0192914 Abstract Understanding the cognitive processes underlying body dissatisfaction provides important information on the development and perpetuation of eating pathology. Previous research suggests that body-dissatisfied women process weight-related information differently than body-satisfied women, but the precise nature of these processing differences is not yet understood. In this study, eye-gaze tracking was used to measure attention to weight-related…
