“Pupillary Reactivity to Social Exclusion: A Window into the Mechanism behind Social Exclusion Detection” Social exclusion causes distress. However, physiological mechanisms behind such distress responses are unclear. We investigated whether pupil dilation, an automatic physiological response, occurs when excluded by humans versus computers. Pupil dilation increased after exclusion by both humans and computers, suggesting fast-acting sensitivity to exclusion may be an evolutionarily ingrained tendency.

“Core Beliefs in Late Adolescence: Factor Structure and Implications for Psychosis, Depression, and Anxiety” Core beliefs contribute to development of psychosis, depression, and anxiety. We found that core beliefs were more factorially complex and linked to attenuated psychotic symptoms in adolescents at ultra-high risk for psychosis, and that they were less factorially complex and linked to depression and anxiety symptoms in non-clinical community adolescents.

“Structural Alterations within Cerebellar Circuitry Are Associated with General Liability for Common Mental Disorders” We examined structural neural correlates of a general psychopathology factor in a large sample of young adults. We identified reduced cortico-cerebellar white matter integrity and gray matter volume as transdiagnostic correlates, suggesting that this circuitry supporting basic information integration, coordination, and monitoring may contribute to general liability for psychopathology.

“Different Sides of the Same Addiction Coin: Common Patterns of Hormone Responses in Problem Gamblers and Heavy Smokers” We compared hormone levels (the DHEA and its sulfate, DHEA-S, to cortisol ratio) at baseline and in response to a stressor in problem gamblers, heavy smokers, and healthy controls. Similar patterns of a blunted stress response emerged in gamblers and heavy smokers, suggesting a common physiological vulnerability to stress.

People Who Value Virtue Show Wiser Reasoning

New Research From Psychological Science
Read about the latest research published in Psychological Science: Educational Attainment and Personality Are Genetically Intertwined René Mõttus, Anu Realo, Uku Vainik, Jüri Allik, and Tõnu Esk In this study, the researchers examined whether phenotypic variation in personality traits is associated with polygenic propensity for educational attainment. The researchers examined more than 3,000 Estonian adults who were part of the Estonian Biobank cohort. The participants gave a blood sample for DNA testing, reported their highest level of educational attainment, and completed an assessment of personality domains of the five-factor model and their 30 facets.
