虽然咖啡因对基本认知功能的影响是众所周知的，但它对更复杂决策的影响，特别是对选择产生的影响，还有待探索。目的探讨咖啡因对日常生活决策情境中选择产生的影响。方法在一项双盲安慰剂对照实验中，参与者（N = 47）接受300 mg咖啡因或安慰剂。参与者必须为一系列熟悉程度不同的现实场景生成选项（他们可以做的事情），然后在这些选项中做出决定。结果分析显示，咖啡因组的参与者产生的选择明显少于安慰剂组的参与者。此外，咖啡因显著减少了选项生成的开始时间，也就是说，咖啡因组的参与者比安慰剂组的参与者生成第一个选项的速度显著快。关于后续选择，我们发现了支持“先选”启发式的证据，即倾向于选择第一个生成的选项。这种倾向既不受咖啡因的影响，也不受对场景熟悉程度的影响。结论在无约束的现实生活决策情境中，脚手架可减少生成的选项，减少生成的起始次数。
RationaleAlthough the effects of caffeine on basic cognitive functions are well-known, its effects on more complex decision making, particularly on option generation, is yet to be explored.ObjectiveWe examined the effects of caffeine on option generation in decision making using everyday life decisional situations.MethodsIn a double-blind placebo-controlled experiment, participants (N = 47) either received 300 mg of caffeine or a placebo. Participants had to generate choice options (things they could do) for a series of high and low familiar real-world scenarios and, subsequently, to decide among these options.ResultsAnalyses revealed that participants in the caffeine condition generated significantly fewer options than participants in the placebo condition. Moreover, caffeine significantly reduced the option generation onset time, that is, participants in the caffeine condition generated their first option significantly faster than participants in the placebo condition. Regarding subsequent choice, we found evidence supporting the “take-the-first” heuristic, that is, the tendency to select the first generated option. This tendency was neither affected by caffeine nor by the familiarity of the scenarios.ConclusionsCaffeine results in fewer options generated in unconstrained real-life decision-making situations and decreases generation onset times.
