There is growing evidence illustrating the negative aspects of reinvestment on everyday life, however its underlying mechanisms remain unclear. The main aim of this study was to empirically clarify the relationship between reinvestment and working memory (WM). A secondary aim was to investigate the contribution of high-frequency heart rate variability (HF-HRV) to WM. Sixty-two participants took part in a within-subject design in which we measured their WM capacity in a low-pressure and a high-pressure condition while their HF-HRV was measured. In addition, they had to fill out scales assessing their dispositional reinvestment. Results showed that the correlation between reinvestment and WM is negative, exists only in the high-pressure condition, and is specific to the decision component of reinvestment and not the movement component. Moreover, a hierarchical regression analysis revealed that under high pressure resting HF-HRV predicted WM performance above DSRS, whereas DSRS did not predict WM performance above resting HF-HRV.
越来越多的证据表明再投资对日常生活存在负面影响,但其潜在机制仍不清楚。本研究的主要目的是通过实证澄清再投资与工作记忆(WM)之间的关系。次要目的是研究高频心率变异性(HF-HRV)对工作记忆的贡献。62名参与者参与了一项被试内设计,我们在测量他们的HF-HRV的同时,在低压和高压条件下测量他们的工作记忆容量。此外,他们还必须填写评估其特质再投资的量表。结果表明,再投资与工作记忆之间的相关性为负,仅存在于高压条件下,且特定于再投资的决策成分而非动作成分。此外,层次回归分析显示,在高压下,静息HF-HRV比DSRS能更好地预测工作记忆表现,而DSRS在预测工作记忆表现方面不如静息HF-HRV。
