Delay discounting and operant demand are two behavioral economic constructs that tend to covary, by degree, with cigarette smoking status. Given historically robust associations between adverse health outcomes of smoking, a strong preference for immediate reinforcement (measured with delay discounting), and excessive motivation to smoke cigarettes (measured with operant demand), researchers have made numerous attempts to attenuate the extent to which behaviors corresponding to these constructs acutely appear in smokers. One approach is episodic future thinking, which can reportedly increase the impact of future events on present decision making as well as reduce the reinforcing value of cigarettes. Graphic cigarette pack warning labels may also reduce smoking by increased future orientation. Experiment 1 evaluated the combined effects of episodic future thinking and graphic warning labels on delay discounting; Experiment 2 evaluated solely the effects of episodic future thinking on delay discounting and operant demand. We observed no statistically significant effects of episodic future thinking when combined with graphic warning labels or when assessed on its own. These results serve as a call for further research on the boundary conditions of experimental techniques reported to alter behaviors associated with cigarette smoking.
延迟折扣和操作性需求是两种行为经济学结构,它们往往会在一定程度上与吸烟状况相关。鉴于吸烟对健康的不良后果、对即时强化(通过延迟折扣测量)的强烈偏好以及对吸烟的过度动机(通过操作性需求测量)之间存在着历史上强有力的关联,研究人员已经多次尝试减轻与这些结构相对应的行为在吸烟者中急性出现的程度。一种方法是情景式未来思维,据报道,这种方法可以增加未来事件对当前决策的影响,并降低香烟的强化价值。图形香烟包装警示标签也可以通过增加对未来的关注来减少吸烟。实验 1 评估了情景式未来思维和图形警示标签对延迟折扣的综合影响;实验 2 仅评估了情景式未来思维对延迟折扣和操作性需求的影响。当与图形警示标签结合使用或单独评估时,我们没有观察到情景式未来思维有统计学上的显著效果。这些结果呼吁进一步研究据报道可以改变与吸烟相关的行为的实验技术的边界条件。
