Abstract [en]

According to the simulation hypothesis, mental imagery can be explained in terms of predictive chains of simulated perceptions and actions, i.e., perceptions and actions are reactivated internally by our nervous system to be used in mental imagery and other cognitive phenomena. Our previous research shows that it is possible but not trivial to develop simulations in robots based on the simulation hypothesis. While there are several previous approaches to modelling mental imagery and related cognitive abilities, the origin of such internal simulations has hardly been addressed. The inception of simulation (InSim) hypothesis suggests that dreaming has a function in the development of simulations by forming associations between experienced, non-experienced but realistic, and even unrealistic perceptions. Here, we therefore develop an experimental set-up based on a simple simulated robot to test whether such dream-like mechanisms can be used to instruct research into the development of simulations and mental imagery-like abilities. Specifically, the hypothesis is that dreams' informing the construction of simulations lead to faster development of good simulations during waking behaviour. The paper presents initial results in favour of the hypothesis.

Abstract [en]

This thesis is concerned with explanations of embodied cognition as internal simulation. The hypothesis is that several cognitive processes can be explained in terms of predictive chains of simulated perceptions and actions.

In other words, perceptions and actions are reactivated internally by the nervous system to be used in cognitive phenomena such as mental imagery.

This thesis contributes by advancing the theoretical foundations of simulations and the empirical grounds on which they are based, including a review of the empiricial evidence for the existence of simulated perceptions and actions in cognition, a clarification of the representational function of simulations in cognition, as well as identifying implicit, bodily and environmental anticipation as key mechanisms underlying such simulations. The thesis also develops the ³inception of simulation² hypothesis, which suggests that dreaming has a function in the development of simulations by forming associations between experienced, non-experienced but realistic, and even unrealistic perceptions during early childhood. The thesis further investigates some aspects of simulations and the ³inception of simulation² hypothesis by using simulated robot models based on echo state networks. These experiments suggest that it is possible for a simple robot to develop internal simulations by associating simulated perceptions and actions, and that dream-like experiences can be beneficial for the development of such simulations.
