Project C1. Aging and the effect of predictivity and utility on perception

众所周知，视觉功能特别容易发生正常的衰老过程，也特别容易出现阿尔茨海默型神经退化。在健康的观察者中，视觉注意功能的某些组成部分，包括感知处理速度和自上而下的控制，受到准备和预期效应的影响。该项目的目的是研究正常和病态衰老如何调节对加工速度和自上而下的注意力控制的主动知觉效应。此外，我们计划评估静息状态脑网络连接变化如何调节这些年龄效应。

Visual functions are known to be particularly prone to normal aging processes and also to beginning Alzheimer-type neurodegeneration. In healthy observers, certain components of visuo-attentional functioning, including perceptual processing speed and top-down control, are influenced by preparation and expectancy effects. The aim of the proposed project is to examine how normal and pathological aging modulate such active perception effects on processing speed and top-down control of attention. Furthermore, we plan to assess how resting state brain network connectivity changes mediate these age effects.
