The attentional control theory (ACT) proposes that trait anxiety disrupts functional efficiency of executive control of attention relating to working memory system such as shifting. ACT also emphasizes the modulatory role of motivation in anxiety on cognitive task performance. The present study investigated the association of trait anxiety-related inefficiencies in attentional shift and working...

Our group previously demonstrated that changes in mood induced by pleasant or unpleasant odors affect the perceived unpleasantness of painful heat stimuli, without significantly altering perceived pain intensity. In the present study, we examined whether changing mood by viewing emotionally laden visual stimuli also preferentially alters pain unpleasantness. Twelve female subjects immersed thei...

INTRODUCTION Preoperative anxiety is common in children and it is associated with an adverse post-operative outcome. The modified Yale Preoperative Anxiety Scale (m-YPAS) was developed to assess preoperative anxiety in children. The purpose of this study was to translate and adapt the m-YPAS to Danish cultural and linguistic conditions and to test its face validity and inter-rater reliability i...

Introduction: Lack of high-quality sleep causes serious side effects like anxiety and changes in plasma concentration of oxalate. The current study aimed to investigate the impact of local extremely low frequency magnetic fields (ELF-MFs) on inducing sleep (sleepiness) and anxiety in male rats. Methods: In this experimental study, 40 male rats were allocated in four groups (n=10). The ELF-MFs ...

How does negative mood affect risk taking? A brief questionnaire was used to measure state anxiety, depression, and fatigue, and a daily mood diary allowed state and trait (average level) mood to be separated. Studies 1 and 2 used natural moods and Study 3 a mood induction procedure. Risk was assessed using hypothetical everyday choice scenarios. Study 1 showed that riskiness was affected by st...

Corticotropin-releasing hormone (CRH) is a central integrator in the brain of endocrine and behavioral stress responses, whereas activation of the endocannabinoid CB1 receptor suppresses these responses. Although these systems regulate overlapping functions, few studies have investigated whether these systems interact. Here we demonstrate a novel mechanism of CRH-induced anxiety that relies on ...

This study investigated the impact of an aversive environmental stimulation on self-reported affective and anxiety states and movement behaviors during a simulated navigation task in a virtual environment (VE). In the experimental task, participants were asked to virtually navigate (within two consecutive sessions), from a starting point to a destination location, across a spatial configuration...

Presurgery anxiety in children may result in preoperative and postoperative complications. Emergence delirium (ED) is a mental disturbance common in children during recovery from general anesthesia. This study investigated the role of preoperative dexmedetomidine on parental separation anxiety and acceptance of wearing an anesthesia mask, and its effectiveness in reducing the incidence and seve...

The recreational drugs, alcohol and 3,4-Methylenedioxymethamphetamine (MDMA, "Ecstasy") have both been shown to cause immune activation in vivo, and they are linked to cognitive impairment and anxiety-like behaviors in rodents. The neuronal effects of these drugs in the hippocampal area, an area that has been a focus of studies aiming to explain the mechanisms underlying anxiety related-disorde...
