Associations of consequences of coronavirus pandemic with anxiety, depression and loneliness: moderating effects of internal resources.

The influence of personal internal resources (IRs) on coping with traumatic events is constantly researched. This study aimed to determine how the SARS-CoV-2 pandemic affected anxiety, depression, and loneliness in two groups at different levels of exposure (low and high) to the infection. We analysed the impact of IRs in the form of the level of hope and self-efficacy on mental reactions (anxiety and depression) and social well-being (loneliness). The study was conducted as an internet survey. Descriptive statistics, correlation analysis, and difference tests were used for preliminary analyses. Structural equation models (SEM) were used for multivariate data analysis. The SEM model revealed that people working in a profession with a higher risk of infection coped better in the pandemic. We observed a higher level of IRs in the higher exposure group, and the consequences were less pronounced. We concluded by stating that the level of hope and sense of self-efficacy could moderate the response in a pandemic situation and constitute protective factors against psychopathological symptoms.

Recognition of extraversion level based on handwriting and support vector machines.

This study investigated whether it is possible to train a machine to discriminate levels of extraversion based on handwriting variables. Support vector machines (SVMs) were used as a learning algorithm. Handwriting of 883 people (404 men, 479 women) was examined. Extraversion was measured using the Polish version of the NEO-Five Factor Inventory. The handwriting samples were described by 48 variables. The support vector machines were separately trained and tested for each sex, using 10-fold cross-validation. Good recognition accuracy (around .7) was achieved for 10 handwriting variables, different for men and women. The results suggest the existence of a relationship between handwriting elements and extraversion.
