Development and validation of implicit behavioral tests assessing perceptual sensitivity to construction hazards

Area of Science:

• Cognitive psychology
• Occupational safety
• Construction management

Background:

• Hazard recognition is crucial for preventing accidents among construction workers.
• Traditional explicit knowledge tests have limitations in assessing practical safety awareness.
• This study introduces implicit behavioral tasks as an innovative assessment method.

Purpose of the Study:

• To develop and evaluate implicit behavioral tasks for measuring perceptual sensitivity to danger in construction sites.
• To provide an alternative to conventional explicit knowledge tests for assessing hazard recognition.
• To investigate cognitive processes underlying effective hazard recognition in high-risk environments.

Main Methods:

• Attentional blink, change blindness, and go/no-go tasks were employed.
• These tasks assessed attentional capture, change detection, and response inhibition.
• Cognitive processes essential for hazard recognition in construction were examined.

Main Results:

• Construction workers showed enhanced attentional allocation to dangerous objects.
• Workers demonstrated heightened change detection for danger-related stimuli.
• Improved inhibition of impulsive reactions to construction hazards was observed compared to a control group.

Conclusions:

• The developed tasks effectively assess cognitive traits related to safety awareness in construction.
• These tasks can be scaled for broader application in construction safety management.
• Integrating these tasks into training allows for targeted interventions for workers with lower perceptual sensitivity to hazards.
