Better cognitive efficiency is associated with increased experimental anxiety

Health anxiety and its association with perceived subjective workload in psychiatric nurses during the COVID-19 outbreak: a correlational study

Background

Health care professionals, especially nurses, experience added workload, and psychological impact during the COVID-19 outbreak. This study aimed to investigate health anxiety and its association with perceived subjective workload in nurses working in psychiatric hospital wards.

Methods

This descriptive correlational study was conducted on 206 nurses working in the psychiatric wards of Razi Psychiatry Hospital in Tabriz, Iran, in 2020-2021. Census sampling was applied and data were collected using the National Aeronautics and Space Administration Task Load Index, and the Health Anxiety Inventory. Data were analyzed using descriptive statistics, t-tests, and Pearson correlation in SPSS software version 16.

Results

The mean (SD) of health anxiety and workload of nurses was 23/22(6/86) score range of 0-54 and 71.46 (12.37) score range of 0-100, respectively. The correlation between the mean of health anxiety and workload was significant only in the temporary dimension.

Conclusions

Given the high workload and moderate level of health anxiety and the significant correlation between health anxiety and the temporary dimension of workload and the important role of appropriate workload in the health of nurses and the quality of nursing care, organizations and nursing managers should provide some strategies, like stuff shortage management in psychiatric wards and creating a suitable organizational culture.

The impact of teleworking technostress on satisfaction, anxiety and performance

The aim of the research project is to find out how technostress influences the satisfaction, anxiety and performance of teleworkers and university students. The growth of technology and the use of digital platforms has given rise to a phenomenon called teleworking, a modality of work that involves remote work with the use of ICTs. However, the faster the use of ICTs in organisations grows, the more difficult it becomes for teleworkers, leading to anxiety and stress. This feeling is known as technostress, and knowing its impact on workers is of vital importance for organizational success. The study was conducted through a literature review and the dissemination of an online questionnaire using PLS software. The analysis validated the measurement scale and analysed the structural model at different stages, which confirmed its validity and reliability. The research concludes by affirming the high relationship between technostress, satisfaction, anxiety and performance. It is highlighted that the lower the technostress, the higher the satisfaction and performance, and the higher the technostress, the higher the anxiety and the lower the satisfaction. This research brings as an added value the validation of a scale of technostress together with the variables satisfaction, anxiety and performance not previously analysed by other researches. In addition, the research provides a series of measures to mitigate the effects of technostress and suggests future lines of research. Thus, it highlights the importance of understanding the impact of technostress on teleworkers, to provide effective measures to mitigate it and thus increase the satisfaction and performance of workers.

Spatial navigation under threat: aversive apprehensions improve route retracing in higher versus lower trait anxious individuals

Spatial navigation is a basic function for survival, and the ability to retrace a route has direct relevance for avoiding dangerous places. This study investigates the effects of aversive apprehensions on spatial navigation in a virtual urban environment. Healthy participants with varying degrees of trait anxiety performed a route-repetition and a route-retracing task under threatening and safe context conditions. Results reveal an interaction between the effect of threatening/safe environments and trait anxiety: while threat impairs route-retracing in lower-anxious individuals, this navigational skill is boosted in higher-anxious individuals. According to attentional control theory, this finding can be explained by an attentional shift toward information relevant for intuitive coping strategies (i.e., running away), which should be more pronounced in higher-anxious individuals. On a broader scale, our results demonstrate an often-neglected advantage of trait anxiety, namely that it promotes the processing of environmental information relevant for coping strategies and thus prepares the organism for adequate flight responses.

Neural resources shift under Methylphenidate: A computational approach to examine anxiety-cognition interplay

The reciprocal interplay between anxiety and cognition is well documented. Anxiety negatively impacts cognition, while cognitive engagement can down-regulate anxiety. The brain mechanisms and dynamics underlying such interplay are not fully understood. To study this question, we experimentally and orthogonally manipulated anxiety (using a threat of shock paradigm) and cognition (using methylphenidate; MPH). The effects of these manipulations on the brain and behavior were evaluated in 50 healthy participants (25 MPH, 25 placebo), using an n-back working memory fMRI task (with low and high load conditions). Behaviorally, improved response accuracy was observed as a main effect of the drug across all conditions. We employed two approaches to understand the neural mechanisms underlying MPH-based cognitive enhancement in safe and threat conditions. First, we performed a hypothesis-driven computational analysis using a mathematical framework to examine how MPH putatively affects cognitive enhancement in the face of induced anxiety across two levels of cognitive load. Second, we performed an exploratory data analysis using Topological Data Analysis (TDA)-based Mapper to examine changes in spatiotemporal brain activity across the entire cortex. Both approaches provided converging evidence that MPH facilitated greater differential engagement of neural resources (brain activity) across low and high working memory load conditions. Furthermore, load-based differential management of neural resources reflects enhanced efficiency that is most powerful during higher load and induced anxiety conditions. Overall, our results provide novel insights regarding brain mechanisms that facilitate cognitive enhancement under MPH and, in future research, may be used to help mitigate anxiety-related cognitive underperformance.

Recognition memory, primacy vs. recency effects, and time perception in the online version of the fear of scream paradigm

Anxiety disorders are characterized by cognitive dysfunctions which contribute to the patient’s profound disabilities. The threat of shock paradigm represents a validated psychopathological model of anxiety to measure the impact of anxiety on cognitive processes. We have developed an online version of the threat of scream paradigm (ToSP) to investigate the impact of experimental anxiety on recognition memory. Two animated passive walkthrough videos (either under threat of scream or safety conditions) were shown to healthy participants. Recognition memory, primacy vs. recency effects, and subjective estimations of the length of encoding sessions were assessed. Subjective anxiety, stress, and emotional arousal ratings indicated that experimental anxiety could successfully be induced (Safe-Threat) or reversed (Threat-Safe) between the two passive walkthrough sessions. Participants exposed to distress screams showed impaired retrieval of complex information that has been presented in an animated environment. In the threat condition, participants failed to recognize details related to the persons encountered, their spatial locations, as well as information about the temporal order and sequence of encounters. Participant groups, which received a threat announcement prior to the first walkthrough session (Threat-Threat vs. Safety-Safety and Threat-Safety vs. Safety-Threat) showed poorer recognition memory as compared to the groups that received a safety announcement (P = 0.0468 and P = 0.0426, respectively; Mann–Whitney U test, Cohen’s d = 0.5071; effect size r = 0.2458). In conclusion, experimental anxiety induced by the online version of the ToSP leads to compromised recognition memory for complex multi-dimensional information. Our results indicate that cognitive functions of vulnerable populations (with limited mobility) can be evaluated online by means of the ToSP.
