Previous research and theories have demonstrated that attentional control plays a crucial role in explaining the choking phenomenon (i.e., the performance decrements) under pressure situations. Attentional control is thought to function through two distinct control strategies: proactive control (i.e., a sustained and anticipatory strategy of control) and reactive control (i.e., a transient strategy of control). However, little is known about how performance pressure affects these control strategies. The present study was designed to address this issue. Participants were instructed to complete a continuous performance task (AX-CPT40) under pressure situations. The results showed that individuals under high-pressure situations tended to use proactive control rather than reactive control. Moreover, performance pressure resulted in a more liberal response bias following an A-cue, consistent with an increased use of proactive control. Importantly, the proactive behavioral index calculated on RTs showed that the increased proactive control mainly occurred in the short interval between the cue and probe, but not in the long interval. This suggests that individuals under high-pressure situations are unlikely to employ a proactive control strategy in a situation that requires more attentional resources. In summary, our results provide initial evidence that performance pressure conditionally enhances proactive control, which contributes to a deeper understanding of the dynamic adjustment of control strategies under pressure situations.
