Study Notes

Situational vs. Exceptional Violations

Exceptional Violation: Occurs when a rule no longer serves its purpose, leading to a worker disregarding it. For instance, a worker might remove their harness in a confined space due to it hindering their work and potentially causing harm.
Situational Violation: Happens when a rule is followed but a situation makes it challenging to comply. For example, a site might have 20 harnesses available for 22 workers, causing some to work without them, despite the rule’s validity.

Construction Workers’ Safety Cognitive Model

This model outlines the cognitive processes involved in construction workers' safety decision-making.
It includes stages like acquiring, understanding, perceiving, selecting, and taking action based on information related to potential hazards and risks.

Heuristics

Definition: Heuristics are cognitive shortcuts used to make decisions quickly, relying on experience and intuition.
Application: They are applied in situations of time pressure, complexity, uncertainty, lack of expertise, or threat, especially for routine tasks.
Cognitive Systems: These shortcuts are associated with System 1 thinking, which is fast, intuitive, and automatic, compared to the slower, deliberate System 2.

Importance of Heuristics

Cognitive Miser: Humans tend to reason in simpler, less effortful ways to conserve limited cognitive resources for more demanding tasks.
Learning: Well-functioning attention and memory systems, critical for thinking and learning, require significant cognitive energy, making heuristics essential.

Heuristic Examples

Recognition Heuristic: If one of two objects is recognized, it's likely to be considered more valuable.
Fluency Heuristic: An object processed more fluently (faster, smoother) is perceived as more valuable.
Affect Heuristic: Decisions are influenced by emotional responses rather than thorough analysis.
Availability Heuristic: Easier-to-recall examples are perceived as more frequent or likely.
Representativeness Heuristic: An object similar to a mental prototype is assumed to share its characteristics.
Default Heuristic: Individuals tend to accept the default option.

Negative Impacts of Heuristics on Construction Safety

Efficiency Tension: Construction often involves tight deadlines and cost pressures, leading to a focus on efficiency over safety.
Availability Heuristic: The vividness of efficiency gains can overshadow the less vivid memory of accidents, prioritizing efficiency.
Affect Heuristic: Strong negative emotions associated with efficiency are less likely to be counterbalanced by less emotionally engaging accident experiences.
Representativeness Heuristic: Previous experiences may not be fully considered in new situations, leading to potential hazards being overlooked.
Risk Habituation: Repeated exposure to a stimulus (e.g., hazards) can lead to desensitization, lowering vigilance and increasing risks.

Strategies to Alleviate Negative Impacts of Heuristics

Reduce Pressure: Address time pressure, complexity, uncertainty, and lack of expertise through clear guidelines, training, and improved management.
Boost Safety Awareness: Utilize safety incentives that evoke positive emotions and vivid, memorable images.

Strategies to Leverage Heuristics for Construction Safety

Virtual Reality (VR) Training: VR training can provide realistic and immersive experiences, minimizing actual harm while exposing workers to virtual accidents.
Vivid Accidents: Presenting virtual accidents with high visual impact aims to influence affect and availability heuristics, promoting safety awareness.
Individual Differences: Consider the different levels of habituation among trainees to ensure VR scenarios are sufficiently vivid for each individual.

Assignment #2

Objective: Develop three real-world interventions that leverage heuristics to improve construction safety.
Focus: Use positive approaches to create new positive impacts, not just offsetting negative ones.
Content: Any type of heuristic can be utilized (e.g., anchoring heuristic).
Submission: October 16th, electronically, no more than 2 pages.
