This study investigated cognitive strategies in mental jigsaw puzzles, integrating mental rotation and translation with a focus on directionality and detour arguments. Unlike object mental rotation tasks, these puzzles introduced physical constraints, revealing systematic directional tendencies in both eye movements and subjective reports. Specifically, smaller protruding objects were consistently directed toward larger indented objects. This was accompanied by longer completion times and reduced linearity, paralleling strategies used in physical puzzle-solving. Behavioral asymmetries observed in the puzzles unexpectedly mirrored those found in object mental rotation tasks. While controlling for mental motion directions showed comparable completion times at 300° between tasks, the study did not fully clarify the role of detours, indicating the need for further research.
本研究调查了心理拼图中的认知策略，将心理旋转和平移结合起来，重点关注方向性和迂回论证。与物体心理旋转任务不同，这些拼图引入了物理限制，揭示了眼动和主观报告中的系统性方向倾向。具体而言，较小的突出物体始终指向较大的凹陷物体。这伴随着更长的完成时间和更低的线性度，类似于解决物理拼图时使用的策略。在拼图中观察到的行为不对称意外地反映了在物体心理旋转任务中发现的不对称。虽然控制心理运动方向显示任务之间在300°时的完成时间相当，但该研究并未完全阐明迂回的作用，表明需要进一步研究。
