Based on the Implicit-Affect-Primes-Effort model, we tested whether the effect of implicitly processed affect primes on cardiovascular responses is limited to settings that call for effort and in which implicit affect can inform about subjective task demand. Participants were presented with letter series and briefly flashed sadness versus happiness primes. Half of the participants were asked to memorize all occurring vowels (achievement context), while the other half merely watched the series (watching context). Responses of cardiac pre-ejection period, heart rate, and systolic and diastolic blood pressure supported the predictions. As expected, in the challenging achievement-context condition, happiness primes led to stronger cardiovascular reactivity than sadness primes. By contrast, reactivity was modest in both affect prime conditions when the participants merely watched the stimuli. That is, the impact of affect primes on cardiovascular responses was limited to a setting that directly called for effort mobilization.
基于内隐情感启动-努力模型，我们测试了内隐处理的情感启动对心血管反应的影响是否仅限于需要努力的环境中，并且内隐情感可以提供关于主观任务需求的信息。参与者被呈现字母序列，并短暂地闪现悲伤与快乐启动。一半的参与者被要求记住所有出现的元音（成就语境），而另一半则只是观看序列（观看语境）。心脏射血前期、心率、收缩压和舒张压的反应支持了这些预测。正如预期的那样，在具有挑战性的成就语境条件下，快乐启动比悲伤启动导致更强的心血管反应。相比之下，当参与者只是观看刺激时，两种情感启动条件下的反应都较为温和。也就是说，情感启动对心血管反应的影响仅限于直接需要努力动员的环境。
