- Dynamical systems perspectives on emotion emphasize the importance of the regulatory interplay between brain, body and environment to adaptive behaviour. We suggest that a key facet of emotions, above all fear, consistent with this perspective lies in the allostatic regulation of constitutive/behavioural dynamics in terms of prediction and behavioural biases linking internal needs to external adaptive concerns. Allostatic emotional regulation in organizationally complex organisms permits enhanced adaptive behavioural flexibility relative to more reactive homeostatic dynamical systems. We discuss emotions as regulatory phenomena and provide a brief description of work in progress that will facilitate the gleaning of insights in this regard.

- Emotions can be considered inextricably linked to embodied appraisals - perceptions of bodily states that inform agents of how they are faring in the world relative to their own well-being. Emotion-appraisals are thus relational phenomena the relevance of which can be learned or evolutionarily selected for given a reliable coupling between agent-internal and environmental states. An emotion-appraisal attentional disposition permits agents to produce behaviour that exploits such couplings allowing for adaptive agent performance across agent-environment interactions. This chapter discusses emotions in terms of dynamical processes whereby attentional dispositions are considered central to an understanding of behaviour. The need to reconcile a dynamical systems perspective with an approach that views emotions as attentional dispositions representative of embodied relational phenomena (embodied appraisals) is argued for. Attention and emotion are considered to be features of adaptive agent behaviour that are interdependent in their temporal, structural and organizational relations.

A Neurocomputational Model of Anticipation and Sustained Inattentional Blindness in Hierarchies

- Anticipation and prediction have been identified as key functions of many brain areas facilitating recognition, perception, and planning. In this chapter we present a hierarchical neurocomputational model in which feedback, effectively predicting or anticipating task-relevant features, leads to sustained inattentional blindness. A psychological experiment on sustained inattentional blindness in human subjects is simulated to provide visual input to a hierarchy of Echo State Networks. Other parts of the model receive input relevant to tracking the attended object and also detecting the unexpected object, feedback from which is then used to simulate engagement in the task and compared to results obtained without feedback, simulating passive observation. We find a significant effect of anticipation enhancing performance at the task and simultaneously degrading detection of unexpected features, thereby modelling the sustained inattentional blindness effect. We therefore suggest that anticipatory /predictive mechanisms are responsible for sustained inattentional blindness.

- According to Noë´s enactive theory of perception, sensorimotor knowledge allows us to predict the sensory outcomes of our actions. This paper suggests that tuning input filters with such predictions may be the cause of sustained inattentional blindness. Most models of learning capture statistically salient regularities in and between data streams. Such analysis is, however, severely limited by both the problem of marginal regularity and the credit assignment problem. A neurocomputational reservoir system can be used to alleviate these problems without training by enhancing the separability of regularities in input streams. However, as the regularities made separable vary with the state of the reservoir, feedback in the form of predictions of future sensory input can both enchance expected discriminations and hinder unanticipated ones. This renders the model blind to features not made separable in the regions of state space the reservoir in manipulated towards. This is demonstrated in a computational model of sustained inattentional blindness, leading to predictions about human behaviour that have yet to be tested.

Towards an Enactive Cognitive Architecture
- 2008
-
Konferensbidrag (refereegranskat)abstract
- This paper presents, not only the ingredients but also a recipe for constructing models and architectures consistent with a wide range of requirements necessary for a strong connection to the enactive theory. The design method we propose, holistic reductionism, provides a piecemeal route to constructing integrated and high functioning cognitive systems, following a pathof ‘re-cortication’ rather than cross species or functional decomposition routes as typically advocated in non enactive paradigms.
