Abstract:
Every day we perceive numerosity and time and make decisions based on that perception. Remarkably, we can make perceptual decisions adaptively even though the range of numerosity or time to be processed changes depending on the context. What makes this possible? To understand the flexibility in perceptual decision making about numerosity and time, it must be helpful to understand the flexibility in the neural representations of them.
Here, I will present my work on numerosity in CiNet and future plans and thoughts on time. In the first part, I demonstrate that some of the brain regions involved in numerosity processing encode the absolute magnitude of numerosity regardless of context, while others flexibly encode the relative magnitude depending on context. In the second part, I will review the literature and discuss how this finding can be extended to time and how numerosity and time can be related.
