We gave 127 undergraduates questionnaires about their iPod and texting dependence and 2 hypothetical delay discounting scenarios related to free downloaded songs and free texting for life. Using regression analyses we found that when iPod dependence was the dependent variable, Text2-excessive use, Text4-psychological and behavioral symptoms, iPod2-excessive use, and iPod3-relationship disruption were significant predictors of discounting. When texting dependence was the dependent variable, Text4-psychological and behavioral symptoms and iPod3-relationship disruption were significant predictors of discounting. These are the first data to show that delay discounting relates to certain aspects of social media, namely iPod and texting dependence. These data also show that across these 2 dependencies, both psychological and behavioral symptoms and relationship disruptions are affected.

发短信依赖性，iPod依赖性和延迟折扣。

我们为127名大学生提供了有关其iPod和短信依赖性的调查问卷，以及2个与免费下载的歌曲和终身免费短信有关的假设性延迟折扣方案。使用回归分析，我们发现，当iPod依赖性为因变量时，Text2过度使用，Text4心理和行为症状，iPod2过度使用以及iPod3关系破坏是折价的重要预测因素。当发短信依赖性是因变量时，Text4的心理和行为症状以及iPod3的关系中断是折价的重要预测因子。这些是第一个显示延迟折扣与社交媒体某些方面有关的数据，即iPod和短信依赖性。这些数据还表明，在这两个依赖项中，
