kiana-mansour-portraitAbout me…

My name is Kiana and I am from Iran. I am working in the Inference in Visual Behaviours lab, Insitut de Neurosciences de la Timone, Marseille, France. I did my undergraduate studies in physics of complex systems in the Polytechnic University of Turin where I found my interest in the brain, an example of complex system with many interacting components.

 

Why I joined PACE…

I found the researcher topics offered within the PACE network exciting. Moreover as an early stage researcher, PACE gives me the opportunity to meet leading researchers and have experience to work with different research teams during my PhD.

My project…

In everyday life, we constantly need to track relevant moving targets in complex environments with our eyes such as, for instance, when we try to catch someone running in the crowd. However, this seemingly simple task demands to deal with several dynamic sources of uncertainty, related to intrinsic, target-related properties or to external, environment-related factors. In addition, one single object has to be selected at a time for accurate visual processing and ocular tracking in presence of a multitude of competing signals.

My goal is to understand the dynamic inference and decision processes underlying smooth eye movements. I will conduct psychophysics and oculomotor recordings on healthy subjects, as well as modeling work, in order to elucidate the effects of sensory uncertainty on the accuracy and the dynamics of visuomotor decisions. Bayesian Inference will provide a general and solid framework for behavioral models. Oculomotor decision times, such as those characterizing the dynamic switch between smooth pursuit and saccades during motion tracking, or transitions between two alternative tracking solutions, will be modeled and benchmarked against the predictions of current models of choice reaction times (“accumulation-to-threshold” models).
