Abstract
The representation of the environment assumes the encoding of four basic dimensions in the brain, that is the 3D space and time. The vital role of time for cognition is a topic that recently attracted increasing research interest. Surprisingly, the scientific community investigating mind-time interactions has mainly focused on interval timing, paying less attention on the encoding and processing of distant moments. The present work highlights two basic capacities that are necessary for developing temporal cognition in artificial systems. In particular, the seamless integration of agents in the environment assumes they are able to consider when events have occurred and how-long they have lasted. This information, although rather standard in humans, is largely missing from artificial cognitive systems. In this work we consider how a time perception model that is based on neural networks and the Striatal Beat Frequency (SBF) theory is extended in a way that besides the duration of events, facilitates the encoding of the time of occurrence in memory. The extended model is capable to support skills assumed in temporal cognition and answer time-related questions about the unfolded events.
Highlights
Our sense of time exhibits unique characteristics that distinguishes it from the typical group of human senses
The fact that numerous event durations can be simultaneously preserved in the system is a valuable addition to interval timing models that enables further processing of the memorized durations
We implement the computational analogous of temporal distance in our model, and we investigate the possibility of using this measure as a representation of when events have occurred in the past
Summary
Our sense of time exhibits unique characteristics that distinguishes it from the typical group of human senses (sight, hearing, touch, smell, and taste). A crucial difference is that the sense of time is not associated with a specific sensory system in the brain. As it is noted in Bruss and Ruschendorf (2010), the perception of time seems different in nature from what we usually understand as perception. It seems to have its own ways and own laws. We can hear a sound, view a light, taste a food as many times as we want
