Abstract

Attentional bias to threat has been almost exclusively examined after participants experienced repeated pairings between a conditioned stimulus (CS) and an aversive unconditioned stimulus (US). This study aimed to determine whether threat-related attentional capture can result from observational learning, when participants acquire knowledge of the aversive qualities of a stimulus without themselves experiencing aversive outcomes. Non-clinical young-adult participants (N = 38) first watched a video of an individual (the demonstrator) performing a Pavlovian conditioning task in which one colour was paired with shock (CS+) and another colour was neutral (CS−). They then carried out visual search for a shape-defined target. Oculomotor measures evidenced an attentional bias toward the CS+ colour, suggesting that threat-related attentional capture can ensue from observational learning. Exploratory analyses also revealed that this effect was positively correlated with empathy for the demonstrator. Our findings extend empirical and theoretical knowledge about threat-driven attention and provide valuable insights to better understand the formation of anxiety disorders. [ABSTRACT FROM AUTHOR]

43. Attention Failures Cause Workplace Accidents: Why Workers Ignore Hazards and What To Do About It

Author

Anderson, Brian A., Kim, Namgyun, Gregoire, Laurent, Yan, Niya, and Ahn, Changbum Ryan

Abstract

Accidents readily occur when workers are not attentive to the hazards of their work. For some professionals, such as workers in the construction and mining industry, exposure to workplace hazards occurs on a daily basis. Such repetitive exposure to workplace hazards poses unique challenges for the attention of workers. This review explores how, in the absence of negative consequences, repetitive exposure to hazards decreases attention to them. Recommendations, informed by the science of attention, suggest how to combat the tendency to ignore frequently-exposed hazards and restore worker vigilance, thereby reducing the frequency of workplace accidents. Experiential training incorporating virtual reality holds some promise.

44. Virtual accident curb risk habituation in workers by restoring sensory responses to real-world warning.

Abstract

In high-risk work environments, workers become habituated to hazards they frequently encounter, subsequently underestimating risk and engaging in unsafe behaviors. This phenomenon has been termed "risk habituation" and identified as a vital root cause of fatalities and injuries at workplaces. Providing an effective intervention that curbs workers' risk habituation is critical in preventing occupational injuries and fatalities. However, there exists no empirically supported intervention for curbing risk habituation. To this end, here we investigated how experiencing an accident in a virtual reality (VR) environment affects workers' risk habituation toward repeatedly exposed workplace hazards. We examined an underlying mechanism of risk habituation at the sensory level and evaluated the effect of the accident intervention through electroencephalography (EEG). The results of pre- and posttreatment analyses indicate experiencing the virtual accident effectively curbs risk habituation at both the behavioral and sensory level. The findings open new vistas for occupational safety training., Competing Interests: The authors declare no competing interests., (© 2022 The Author(s).)
