Recalling future intentions (i.e., prospective memory, PM) plays an essential role in everyday life, but sometimes, if the person is involved in a demanding ongoing task, PM is unsuccessful. This is especially relevant for bilinguals who, in many situations, have to recall intentions while performing a task in their second language (L2). Our aim was to explore whether PM is modulated by the linguistic context in which PM takes place. In this study, bilinguals performed a PM task in their first (L1) or second language (L2). We also manipulated the demands of the ongoing task (early/late updating) and the PM cue (focal/non-focal). In general, results showed an overall impairment in the recall of future intentions when the task was performed in L2. This impairment was especially evident in the more demanding conditions, suggesting that increments in attentional demands due to L2 processing hinder the processes required for prospective remembering.

回忆未来意图（即前瞻记忆，PM）在日常生活中起着至关重要的作用，但有时，如果一个人正在从事一项要求较高的持续任务，PM 就会不成功。这对于双语者尤其重要，他们在许多情况下必须在用第二语言（L2）执行任务时回忆意图。我们的目的是探索 PM 是否受到 PM 发生的语言环境的调节。在这项研究中，双语者用他们的第一语言 (L1) 或第二语言 (L2) 执行 PM 任务。我们还操纵了正在进行的任务（早期/晚期更新）和 PM 提示（焦点/非焦点）的需求。总的来说，结果显示，当在第二语言中执行任务时，对未来意图的回忆会受到整体损害。这种损害在更苛刻的条件下尤其明显，
