Drifke, Tiger, and Gifford (2019) showed that preschool-aged children’s preferences for otherwise equated choice- and no-choice conditions could be shifted by pairing either condition with higher quality stimuli (either higher preference or larger magnitude edibles). The current study replicated this arrangement and examined changes in equated choice and no-choice selections when each were intermittently associated with either immediate or delayed access to preferred stimuli. Similar to Drifke et al., these pairings produced reliable and systematic shifts in participant preferences.

通过差异增强器即时性的历史来改变选择机会的偏好

Drifke，Tiger和Gifford（2019）表明，学龄前儿童对原本相等的选择和无选择条件的偏好可以通过将任一条件与更高质量的刺激（更高偏好或更大数量的食物）配对来改变。当前的研究重复了这种安排，并检查了当等式选择和无选择式选择中的每一种间歇性地与立即或延迟获得首选刺激相关联时的变化。与Drifke等类似，这些配对对参与者的偏好产生了可靠而系统的转变。
