Self salience across age range

项目摘要

We have recently demonstrated that our perception is enhanced for stimuli that are associated with ourselves relative to stimuli that are associated with other people. That is, stimuli associated to ourselves have increased 'self salience'. There is also evidence that our tendency to prioritize ourselves increases as we age, and this may contribute to other changes in social cognition in older individuals - an example being the ability to see the view of other people. In this project we will conduct a detailed analysis of whether ageing leads to increases in self saliency in perception, and whether such effects predict stronger self-prioritization in higher-level tasks such as face recognition, memory and seeing the viewpoint of other people. In Part 1 of the project we will test whether the self-bias in perception is increased in older people, whether there are changes in particular perceptual processes, and how these changes in behaviour relate to changes in brain activity. Part 2 will evaluate two potential factors that might lead to alterations in self-bias - the reward and the emotional value of self-related information. Are age-related changes due to older adults showing stronger effects of reward and/or stronger effects of emotion on perception? In Part 3 we will assess if age-related changes in self salience in perception predict changes in higher-level tasks (face recognition, memory, seeing others' viewpoints). In addition, by testing brain lesioned patients with reduced self-bias in perception, we will evaluate if perceptual biases are required in order to generate self-prioritization effects in higher-level tasks. The project will provide a fine-grained analysis of whether and how self-related processing changes as we age.

我们最近已经证明，相对于与他人相关的刺激，我们对与自己相关的刺激的感知会增强。也就是说，与我们自己相关的刺激增加了“自我突出”。还有证据表明，随着年龄的增长，我们优先考虑自己的倾向会增加，这可能有助于老年人社会认知的其他变化-例如看到其他人观点的能力。在这个项目中，我们将详细分析衰老是否会导致感知中自我显着性的增加，以及这种影响是否会预测更强的自我优先级在更高级别的任务中，如面部识别，记忆和看到其他人的观点。在该项目的第一部分，我们将测试老年人感知中的自我偏见是否增加，特定感知过程是否发生变化，以及这些行为变化如何与大脑活动的变化相关。第二部分将评估两个可能导致自我偏见改变的潜在因素--奖励和自我相关信息的情感价值。与年龄相关的变化是否是由于老年人表现出更强的奖励效应和/或更强的情绪效应对感知的影响？在第3部分中，我们将评估与年龄相关的感知自我显著性变化是否能预测更高级别任务（面部识别，记忆，观察他人的观点）的变化。此外，通过测试大脑损伤患者减少知觉的自我偏见，我们将评估是否需要知觉偏见，以产生自我优先级的影响，在更高层次的任务。该项目将提供一个细粒度的分析是否以及如何自我相关的处理变化，因为我们的年龄。
