The influence of aging on the dynamics of performance monitoring and change-of-mind decisions

Due to improvements in health care systems and medical care in most developed countries (such as Germany and Australia), the average life expectancy has risen well above 80 years in recent years. Aging, however, has several direct and indirect effects on cognitive functions, for example decision-making and cognitive control, that are important to understand in order to improve the quality of life of elderly people.

This project will investigate whether the ability to change one’s mind and correct errors is directly dependent on processing decision-relevant sensory evidence, and whether healthy elderly people rely on sensory information more than younger people. The project will comprise response time modelling, the analysis of response force profiles, and electroencephalography (EEG) to predict decisions and error correction processes directly from brain activity
