Abstract:

Change blindness is one of the main causes of human factors errors in traffic operations, posing a serious threat to public safety. This study employed an experimental paradigm of global motion direction transients to induce change blindness. Through three experiments, it systematically examined the effects of attention and memory representation on change blindness in traffic scene images during turning. Experiment 1 manipulated the movement speed, movement path, and change type of the scenes. Among these, movement speed might affect change detection by intensifying competition for attentional resources at the moment of turning. The results showed that faster movement significantly exacerbated change blindness only under turning conditions, with no significant effect under straight motion conditions. Experiment 2 controlled movement speed while manipulating movement time (pre-change), movement path, and change type. Here, the duration of the original scene presentation might influence change detection by enhancing the precision of memory representations. It was found that longer encoding time for memory representations could alleviate change blindness within a limited range. Experiment 3 controlled both movement speed and time while manipulating movement path and change type under different levels of expectation, which were established based on the probability distribution of turning directions along the path. The results indicated that individuals demonstrated better detection performance for target changes under high-expectation conditions. In summary, change blindness during the turning motion of traffic scene images stems from the combined effects of attentional resource competition and the limited nature of memory representations. Furthermore, expectation may endogenously modulate both the allocation of attention and the effective construction of memory representations, thereby influencing the occurrence of change blindness. These findings support and extend the attention-representation theory of change blindness.
