The collaborative nature of construction workplaces underscores the significance of team dynamics, wherein social influences play a pivotal role in shaping workers’ safety performances. Within this context, individuals’ risk perception can influence their propensity for engaging in risky behaviors. While previous research extensively delves into the association between risk perception and unsafe behaviors, this interplay in the presence of a peer remains unexplored. To address this gap, this study examined changes in individuals’ cognitive and affective risk perception and risk-taking behaviors while working alongside safe and unsafe peers. Findings revealed that individuals with higher risk perception are less susceptible to the adverse effects of peer pressure and showed a reduced inclination towards engaging in at-risk behaviors while completing a roofing task. These findings contribute valuable insights to the construction community to be cognizant of these social dynamics and take proactive measures to counteract negative peer influences undermining the safe environment.

The Neural Basis of Risk Attitude in Decision-Making Under Risk: fNIRS investigation of the Simulated Electrical Construction Task
Risk propensity, or individuals' attitude toward risk, can highly impact individuals' decision-making in high-risk environments since those who merely focus on positive consequences associated with high-risk acts are more likely to engage in risk-taking behaviors. Previous studies identified activation in the prefrontal cortex during decision-making under risk to be a sign of an individual's attitude toward risks. To investigate whether such past work - prevalent in behavioral research domains - translates into construction safety, this study conducted an experiment in a mixed-reality environment using functional near-infrared spectroscopy (fNIRS) technology to examine whether positive risk attitudes cause individuals to adopt risky construction behaviors and whether the activation of the prefrontal cortex of the brain can represent such risk attitudes. The results show that participants with a higher risk propensity had a higher brain activation during the risky electrical tasks; these individuals merely focused on gains, which motivated them to increase their risk-taking behavior and consequently experience more electrical accidents. Understanding workers' attitudes toward risk will thus influence future understandings of decision behavior under risk.

Schiffer, Marike (Ed.)Previous research points to the heritability of risk-taking behaviour. However, evidence on how genetic dispositions are translated into risky behaviour is scarce. Here, we report a genetically informed neuroimaging study of real-world risky behaviour across the domains of drinking, smoking, driving and sexual behaviour in a European sample from the UK Biobank (N = 12,675). We find negative associations between risky behaviour and grey-matter volume in distinct brain regions, including amygdala, ventral striatum, hypothalamus and dorsolateral prefrontal cortex (dlPFC). These effects are replicated in an independent sample recruited from the same population (N = 13,004). Polygenic risk scores for risky behaviour, derived from a genome-wide association study in an independent sample (N = 297,025), are inversely associated with grey-matter volume in dlPFC, putamen and hypothalamus. This relation mediates roughly 2.2% of the association between genes and behaviour. Our results highlight distinct heritable neuroanatomical features as manifestations of the genetic propensity for risk taking.more » « less

Construction is one of the most hazardous industries, in part because it involves dynamic and cognitively demanding tasks that tax workers' mental resources. Though some previous studies showed increases in workers' mental load can adversely affect the safety-critical function of workers' situational awareness, limited previous work has utilized machine learning (ML) techniques for mental load classification models with Functional Near-Infrared Spectroscopy (fNIRS) signals to passively identify at-risk workers suffering excessive mental loads. Within an immersive mixed-reality environment simulating an electrical construction task, this study employed ensemble modeling to classify workers' mental load via their fNIRS-captured brain activation. Beyond identifying the prefrontal and motor cortices as the most important brain areas contributing to ML-driven mental load classifications when using fNIRS, this paper also proposes a mental load classification methodology that synthesizes neuroimaging data with individuals' risk-propensity scores to address the limitations of existing personalized and generalized ML models. The results reveal better performance for fNIRS-based mental load classifications given participants' personal risk propensity (risk-seeker and risk-averse). This research, therefore, (1) offers valuable insights into the importance of identifying at-risk workers who are more likely to experience impaired cognitive processing and situational awareness due to increased mental load, and (2) sheds light on reliable pipelines for developing fNIRS-based mental load classification.more » « less

The inherently social environment of construction job sites can exacerbate high incident rates due to social influence and peer pressure. Workers’ risk perception (RP) and risk tolerance (RT) have been identified as key factors contributing to their involvement in high-risk behaviors. However, there is a paucity of research on how workers’ RT, as a personality trait, impacts and moderates the relationship between RP and risk-taking behaviors in the presence of a risky peer. To fill this gap, this study empirically examined the changes in workers’ stress levels, due to the perceived risk, and risk-taking behaviours given their RT in the presence of an unsafe peer. An augmented virtuality (AV) environment simulating a roofing task was developed to capture participants’ real-time physiological and risk-taking measures while performing the task alongside the unsafe peer. The findings showed that RT moderates the relationship between participants’ risk perception and risk-taking behaviors in a social setting. Specifically, participants with higher risk tolerance were less resistance to the imposed peer pressure and showed higher risk-taking behaviors in the presence of the unsafe peer due to their misperception of risks. Given the challenge of altering individuals’ personality traits, this study underscores the importance of providing workers with higher risk tolerance with effective interventions to improve their risk perception, counteract excessive risk-taking, and mitigate the adverse effects of peer pressure within construction job sites.more » « less

Worthy, Darrell A. (Ed.)When making decisions involving risk, people may learn about the risk from descriptions or from experience. The description-experience gap refers to the difference in decision patterns driven by this discrepancy in learning format. Across two experiments, we investigated whether learning from description versus experience differentially affects the direction and the magnitude of a context effect in risky decision making. In Study 1 and 2, a computerized game called the Decisions about Risk Task (DART) was used to measure people’s risk-taking tendencies toward hazard stimuli that exploded probabilistically. The rate at which a context hazard caused harm was manipulated, while the rate at which a focal hazard caused harm was held constant. The format by which this information was learned was also manipulated; it was learned primarily by experience or by description. The results revealed that participants’ behavior toward the focal hazard varied depending on what they had learned about the context hazard. Specifically, there were contrast effects in which participants were more likely to choose a risky behavior toward the focal hazard when the harm rate posed by the context hazard was high rather than low. Critically, these contrast effects were of similar strength irrespective of whether the risk information was learned from experience or description. Participants’ verbal assessments of risk likelihood also showed contrast effects, irrespective of learning format. Although risk information about a context hazard in DART does nothing to affect the objective expected value of risky versus safe behaviors toward focal hazards, it did affect participants’ perceptions and behaviors—regardless of whether the information was learned from description or experience. Our findings suggest that context has a broad-based role in how people assess and make decisions about hazards.more » « less
