Summary
This study reveals temporal visual search patterns in construction hazard recognition (CHR). Participants prioritize electrical hazards at interaction points and use scene-related or norm-guided strategies for PPE hazards, informing safety training and computer vision development.
Area of Science:
- Construction Safety
- Cognitive Psychology
- Computer Vision
Background:
- Current construction hazard recognition (CHR) studies lack temporal analysis, limiting understanding of visual patterns.
- Existing methods rely on sparse fixations or cross-sectional data, failing to capture dynamic visual behavior.
Purpose of the Study:
- To investigate temporal visual search patterns in construction hazard recognition (CHR).
- To identify cognitive strategies underlying these visual patterns.
- To enhance computer vision techniques and safety training for CHR.
Main Methods:
- An experimental study simulating CHR to record participants' visual behavior.
- Temporal qualitative comparative analysis (TQCA) applied to visual sequences.
- Results triangulated with post-event interviews.
Main Results:
- For electrical hazards, participants prioritize the interaction point between energy sources and wires.
- Two distinct visual strategies identified for PPE hazards: 'scene-related' (bottom-up) and 'norm-guided' (top-down).
- Findings extend the recognition-by-components (RBC) and gestalt models.
Conclusions:
- Temporal visual search patterns offer deeper insights into CHR than static analyses.
- Understanding cognitive strategies informs the development of more effective safety training and computer vision systems.
- This research provides a practical guide for safety training and theoretical foundations for CHR computer vision.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
