Abstract

It is common to make risky decisions under time pressure. However, there are ongoing debates regarding the interpretation of the intrinsic mechanisms through which time pressure influences risky decision-making. The current study, combining a sequential risk-taking task, behavioral modeling, and time-resolved multivariate pattern analysis on electroencephalography signals, explored the intrinsic mechanisms underlying the influence of time pressure on risky decision-making. Results from both the behavioral and neural levels indicated that under time pressure, decision-makers enhanced their computation of the value of different options, with this computation primarily based on the potential benefits of options, and made more conservative decision. Additionally, under time pressure, decision-makers' emotion experience was related to the indicator of valuation stage (i.e., decoding accuracy) of decision-making and they spent less time on the subsequent selection stage. The current study highlights that, during risky decision-making under time pressure, the brain does not suppress a particular information processing process; instead, it operates in an accelerated manner.

时间压力下人类决策的加速神经计算。

在时间压力下做出冒险的决定是很常见的。然而，关于时间压力影响风险决策的内在机制的解释仍在进行辩论。本研究结合时序冒险任务、行为建模和脑电图信号的时间分辨多变量模式分析，探讨了时间压力对风险决策影响的内在机制。行为层面和神经层面的结果都表明，在时间压力下，决策者对不同选项价值的计算增强，主要基于选项的潜在收益进行计算，并做出更保守的决策。此外，在时间压力下，决策者的情绪体验与决策的估值阶段（即解码精度）指标相关，并且他们在随后的选择阶段花费的时间较少。目前的研究强调，在时间压力下的风险决策过程中，大脑并没有抑制特定的信息处理过程；相反，它以一种加速的方式运作。

期刊介绍： Founded in 1964, Psychophysiology is the most established journal in the world specifically dedicated to the dissemination of psychophysiological science. The journal continues to play a key role in advancing human neuroscience in its many forms and methodologies (including central and peripheral measures), covering research on the interrelationships between the physiological and psychological aspects of brain and behavior. Typically, studies published in Psychophysiology include psychological independent variables and noninvasive physiological dependent variables (hemodynamic, optical, and electromagnetic brain imaging and/or peripheral measures such as respiratory sinus arrhythmia, electromyography, pupillography, and many others). The majority of studies published in the journal involve human participants, but work using animal models of such phenomena is occasionally published. Psychophysiology welcomes submissions on new theoretical, empirical, and methodological advances in: cognitive, affective, clinical and social neuroscience, psychopathology and psychiatry, health science and behavioral medicine, and biomedical engineering. The journal publishes theoretical papers, evaluative reviews of literature, empirical papers, and methodological papers, with submissions welcome from scientists in any fields mentioned above.
