Previous studies have shown that episodic memory is affected by language. Memories can be coded with language and language is also the main modality used to recall those memories. It is also well established that episodic memory is affected by emotion, so that higher affective salience leads to better encoding. In addition, bilinguals seem to have better recognition abilities when tested in their first than in their second language. There is also evidence that emotional arousal is higher in the the first than the second language. The aim of this project is to investigate the nature of the interaction between the three factors described above, that is, how memorisation and recall, affective salience and language use interact in bilinguals. The project aims to find evidence for such interactions both at an explicit (conscious, metacognitive) and an implicit (unconscious, automatic) level, based on records of reactions times, EEG measures and explicit answers to questionnaires.To do so, the project will test Welsh-English bilinguals (and possibly another pair of languages, such as Spanish-English bilinguals) in three different experimental paradigms. The experiments will gradually investigate different levels of complexity and representation, namely pictures, words, phrases, and sentences. The tasks used will invite participants to observe images or videos of short interactions that could have positive, negative, or neutral affective valence. Participants will be asked to determine whether the stimuli presented have previously been shown (old) or not (new), a difference which can be detected both in overt behavioural measures and implicit measures derived from EEG.We predict that items of higher affective valence will be recognised faster and more accurately than neutral items, with a tendency for effects to be stronger in the case of positive valence. However, it is also expected that affective items will be more likely to induce false recognition (new items identified as old) than neutral items. Language of operation is expected to modulate these effects, so that both hits and false alarms are more prominent in the first language than the second, indicative of a great sensitivity of the participant in the first language.

先前的研究表明，情景记忆受到语言的影响。记忆可以用语言编码，语言也是用来回忆这些记忆的主要形式。情节记忆也受到情绪的影响，因此更高的情感显著性导致更好的编码。此外，双语者似乎有更好的识别能力时，测试在他们的第一个比在他们的第二语言。也有证据表明，第一语言比第二语言更能激发情绪。本研究的目的是探讨上述三个因素之间的相互作用的性质，即记忆和回忆，情感突显和语言使用如何在双语者中相互作用。该项目旨在通过对反应时间的记录、脑电图测量和对问卷的明确回答，在外显（有意识的、元认知的）和内隐（无意识的、自动的）两个层面上寻找这种相互作用的证据。为此，该项目将在三种不同的实验范式中测试威尔士-英语双语者（可能还有另一对语言，如西班牙-英语双语者）。实验将逐步研究不同层次的复杂性和表征，即图片，单词，短语和句子。所使用的任务将邀请参与者观察可能具有积极，消极或中性情感效价的简短互动的图像或视频。参与者将被要求确定所呈现的刺激是否以前已经显示（旧）或不（新），这可以检测到的差异，在两个公开的行为措施和隐式措施来自EEG.We预测，项目的情感价较高的将被识别速度更快，更准确地比中性项目，与一种倾向的效果更强的情况下，积极的效价。然而，它也预计，情感项目将更容易引起错误的识别（新项目识别为旧）比中性项目。预期操作语言会调节这些效果，使得命中和误报警在第一语言中比第二语言更突出，表明参与者在第一语言中的高度敏感性。
