Cognitive Representation of Facial Motion: Investigation of Normal and Impaired Cross-Feature Integration

在我的博士学位中，我想测试我们整合面部特征信息的能力是否会影响我们身份表征的稳定性。虽然这一点以前没有被探索过，但我假设我们能够整合动态面部信息的程度决定了我们身份匹配能力的速度和准确性。解释一下，我认为通过成功整合跨特征运动学习的身份表征比没有整合的身份表征更稳定，在这个假设下，健康的参与者应该能够形成更稳定的身份表征，他们整合了跨特征的信息，而不是他们没有整合的身份。反过来，我认为ASD参与者在这两种情况下都不会表现出稳定性的好处--鉴于他们没有体验到虚幻的减速效应，我假设他们整合跨特征运动的能力受到了损害。当然，为了确保跨特征整合与表征建立有因果关系，而不仅仅是相关的，我们应该进行一项试点研究。我建议，不同的程度，参与者可以得到跨功能集成的好处应该预测的稳定性所产生的表示。这样的初步发现将加强的论点，即虚幻的放缓作为代理我们的能力，整合运动信息的功能。一旦这个代理建立，初始设置应该是一个行为研究探索RG稳定性的差异配对身份视觉搜索性能的健康参与者。随后，我们应该比较NTs和ASD表征的稳定性。

In my D.Phil, I would like to test if our ability to integrate information across facial features influences the stability of our identity representations. Though this has not been explored previously, I hypothesize that the degree to which we are able to integrate dynamic facial information dictates the speed and accuracy of our identity-matching ability. Explicitly, I imagine that representations of identities learnt through successful integration of cross-feature movement are more stable than those learnt without such integration.Under this assumption, healthy participants should be able to form more stable representations of identities for which they integrate information across features than of identities for which they do not. In turn, I suggest that ASD participants would not show a stability benefit in either case - given that they do not experience an illusory slowing effect, I hypothesize their ability to integrate motion across features to be impaired.Of course, to ensure that integrating across features is causally involved with representation building and not merely correlated, we ought to conduct a pilot study. I suggest that varying the degree to which participants can derive a benefit of cross-feature integration should predict the stability of a resulting representation. Such initial finding would strengthen the argument that illusory slowing serves as a proxy of our ability to integrate motion information across features.Once this proxy is established, an initial setup ought to be a behavioural study exploring differences in RG stability for paired-identity visual search performance of healthy participants. Subsequently, we should compare stability of NTs' and ASDs' representations.
