Do animals have thoughts and feelings? Could robots have minds like our own? Can we ever know, or will the answer be forever out of our reach? David McFarland explores the answers to these questions, drawing not only on the philosophy of mind, but also on developments in artificial intelligence, robots, and the science of animal behaviour.

Abstract The frame problem is a problem that arises when an agent attempts to assess the consequences of future behaviour. Strictly, it is a problem of modelling that arises during planning. The problem arises because many of the possible consequences of a planned action are not really relevant to the decision whether to perform the action. The frame problem is typical of the classical approach to artificial intelligence, but it is evident that animals do not suffer from this problem. In (...) this paper it is suggested that animals can circumvent the frame problem because their decision?making architecture is very different from that traditionally used in artificial intelligence.

Abstract Motivation in an automaton, whether it be artificial or animate, is simply that aspect of the total state that determines the behaviour. In an autonomous agent, which has a degree of self?control, the motivational state includes a cognitive evaluation of the likely consequences of possible future behaviour. Such evaluation implies optimization with respect to some motivational criterion.

Abstract In this paper we address three concepts that are much talked about in the animal robotics community. These concepts are (1) representations, (2) goals, and (3) minimal cognition. We want to distinguish between information as an objective commodity and representation as something which involves a user, i.e. a system which accesses and uses information. Information per se lies out there and exists independently of any system that makes use of it. Representations presuppose design and require a user. We want (...) to distinguish different kinds of purposive behaviour, which involve different notions of goals, which themselves appear to be different from the point of view of the agent, the designer and the naive observer. We want to try to define cognition in terms of the minimal criteria that would be acceptable in view of our definitions of representations and goals. We recognise that full?blown cognition may require ingredients other than those of minimal cognition. (shrink)
