多目标追踪中“线索”研究的贡献

Cue effects in multiple object tracking(MOT) tasks

多目标追踪范式是探讨动态情景下注意加工过程的成熟技术,其对不同阶段注意线索加工与利用的分析,对深入了解注意的动态信息加工过程具有重要意义。从注意线索的视角述评呈现阶段的内源性线索与外源性线索以及追踪阶段的目标数量动态变化和轨迹线索的研究成果及限制因素,提出多目标线索研究是客体档案理论与视觉索引理论之争的关键。虽然多目标追踪范式为内源性线索、外源性线索的提取与策略等研究提供很多便利,但目前该范式在线索的认知资源分配和加工策略上仍有研究留白,尚需进一步探索。

Multiple object tracking （MOT）, a wildly used paradigm, offers an opportunity to analyze the attention processes in dynamic context. Endogenous cuing and exogenous cuing could be separated by the difference of processing time span during target acquisition （TA） phase. The location and feature argument between the Object File Theory and the Visual Index Theory was well investigated by juggling variant and trajectory variant, which either alternated the features of objects within a trail or fixed trajectory of targets, distractors, or both of them. However researches on cognitive resource allowance and strategy has not been fully discussed at now.
