Expectation biases could affect decision making in trait anxiety. Studying the alterations of feedback processing in real-life risk-taking tasks could reveal the presence of expectation biases at the neural level. A functional relevance of the feedback-related negativity (FRN) is the expression of outcome expectation errors. The aim of the study was to investigate whether nonclinical adults wit...

Background and Objectives: Studies have shown that patients awaiting coronary angiography (CA) are often anxious. High level of anxiety can lead to physical and psychological stress with adverse effects on organs, es‌pecially heart. There is limited information on state and trait anxiety level in these patients in the literature. This study was thus designed to investigate the level of these tw...

We examined whether anterior and posterior hippocampal subregions in humans show distinct relationships to state and trait anxiety. In rodents, the ventral (but not dorsal) hippocampus is critically involved in contextual anxiety, whereas dorsal hippocampus is affected by chronic stress and genetically bred trait anxiety. These studies suggest that state forms of anxiety may be more associated ...

Introduction: Rhinoplasty is one of the most common cosmetic surgeries occasionally associated with complications, such as acne lesions. Anxiety reportedly leads to the emergence or exacerbation of acne lesions.   Materials and Methods: This cross-sectional study was conducted on 147 patients undergoing rhinoplasty. The patients were assigned into two groups of case (wit...

Koro is regarded as a psychogenic acute anxiety reaction since last forty years. In spite of quite a few research publications on koro during last twenty years, no report on psychometric assessment of anxiety level in Koro is available to substantiate this diagnostic status. The present study in this context is the first attempt of psychometric measurement of anxiety proneness or trait anxiety ...

This experimental study aimed to evaluate the effect of relaxation techniques on anxiety levels, and the relation between anxiety and the concentration of Immunoglobulin A. The study was carried out in a maternity hospital in a city of the State of Espírito Santo, Brazil. The sample was composed of 60 puerperae. The information on the variables: age, education, marital status, type of childbirt...

Two experiments determined the effects of competitive trait anxiety, success-failure, and sex on the performance of 10- to 12 yr.-old children competing on a complex motor maze. Competitive trait anxiety was assessed by the Sport Competition Anxiety Test and success-failure was induced by giving bogus win-loss feedback. High and low competitive trait-anxiety children were randomly assigned to o...

In a recent article, Wilkins, Hjelle, and Thompson (1977) argued that unlike the Dabrowski-deGrace hypothesis, self-actualized Ss should have lower levels of manifest anxiety than low self-actualized Ss. Wilkins et al. demonstrated that this was indeed a preferable hypothesis. The present experiment concerns the relationship of actualization to state and trait anxiety. Ss were administered the ...

Converging evidence identifies trait optimism and the orbitofrontal cortex (OFC) as personality and brain factors influencing anxiety, but the nature of their relationships remains unclear. Here, the mechanisms underlying the protective role of trait optimism and of increased OFC volume against symptoms of anxiety were investigated in 61 healthy subjects, who completed measures of trait optimis...
