Who Are You Expecting? Uncertainty and Bias in High-Level Vision

众所周知，期望在我们如何感知人们的性别、年龄和其他属性方面发挥着重要作用，这对指导我们与他们的互动至关重要。预期是在知觉层面还是认知层面上发挥影响，目前还没有确定。这个项目将把一个数学模型应用于参与者在不确定条件下做出的一系列判断，该模型说明了预期如何影响知觉。该模型旨在描述这些期望如何影响对诸如性别、年龄和吸引力等属性的知觉，以便对人的知觉的一个关键方面产生理解，并为进一步的研究提供新的理论基础。

It is well known that expectation plays a large role in how we perceive the sex, age and other attributes of people, crucial to guiding our interactions with them. It has not yet been established whether expectation exerts its influence at a perceptual or cognitive level. This project will apply a mathematical model of the way in which expectation can influence perception to a range of judgements made by participants under conditions of uncertainty. The model aims to allow the description of how such expectations influence perception of attributes such as sex, age and attractiveness, in order to generate understanding of a key aspect of person perception and provide a novel theoretical foundation for further research.
