Cognitive control and tonic immobility (TI) have both been implicated in the development of PTSD, but it is not known how these factors are related. The present study investigated if a specific form of cognitive control (attentional control) would moderate the relationship between TI and intrusive memories.
Participants (N = 43) completed the Attentional Control Scale (ACS) before watching an aversive film. They completed the Tonic Immobility Scale (TIS, with an immobility and fear subscale: TIS-TI and TIS-Fear) afterwards and recorded intrusive memories of the film in the subsequent week.
TIS-TI was related to intrusion frequency, while ACS was not. However, ACS had a moderating role; the relationship between TIS-TI and intrusion frequency was significant in low ACS but not in high ACS participants. The TIS-Fear subscale was not related to intrusion frequency in low ACS or high ACS participants.
Replication of the results is merited in selected extreme groups and males.
The results may imply that enhanced attentional control serves as a protective factor against the development of intrusive memories after trauma.
认知控制和强直不动（TI）都与 PTSD 的发展有关，但尚不清楚这些因素之间的关系如何。本研究探讨了特定形式的认知控制（注意控制）是否会调节 TI 与侵入性记忆之间的关系。
参与者（N=43）在观看厌恶电影前完成了注意力控制量表（ACS）。之后他们完成了强直不动量表（TIS，包括强直不动和恐惧分量表：TIS-TI 和 TIS-Fear），并在接下来的一周记录电影的侵入性记忆。
TIS-TI 与侵入频率有关，而 ACS 则没有。然而，ACS 具有调节作用；在低 ACS 参与者中，TIS-TI 与侵入频率之间的关系显著，但在高 ACS 参与者中则不显著。TIS-Fear 分量表与低 ACS 或高 ACS 参与者的侵入频率无关。
在选定的极端群体和男性中值得复制这些结果。
结果可能意味着增强的注意力控制可作为创伤后侵入性记忆发展的保护因素。
