摘　　要：目的:考察在无提示线索、内源性提示线索和外源性提示线索时时间表征的空间-时间反应编码联合效应(spatial-temporal association of response codes,STEARC)。方法:以8个代表过去意义的时间词、8个代表将来意义的时间词为刺激材料,以判断其时间意义为任务,采用Posner的经典实验范式进行研究。结果:无线索提示时,注意与非注意条件下都没有出现STEARC效应;内源线索提示时,只有注意条件下出现STEARC效应;外源线索提示时,注意与非注意条件下都只有右手出现了STEARC效应。结论:注意水平影响STEARC效应的大小,线索提示的有效性是重要因素;内源性注意与外源性注意都可以产生STEARC效应,外源性注意的作用大于内源性注意。Objective： To investigate the spatial-temporal association of response codes effect（STEARC） in time repre- sentation under three types of attentional conditions： no cue, endogenous cue and exogenous cue. Methods： By using a typi- cal Posner experiment paradigm, subjects were asked to judge what the 8 past temporal words and 8 future temporal words means in three conditions. Results＂ In no-cue condition, there was no STEARC effect. In endogenous cues condition, the STEARC effect appeared in the attended condition; In the exogenous cues condition, STEARC effect showed in both attend- ed condition and unattended condition. Conclusion： Attention has varied influences on the STEARC effect based on differ- ent referential cues,in which the endogenous cue and exogenous attention both effects the STEARC effect, but the effect of the former is larger than the latter.
