Could computers ever be conscious? Will they ever have ideas that one could attribute to them and not to the programmer? Will robots be able to 'feel pain', instead of processing bits from sensors informing about danger? Will they have true emotions? These questions may never be answered, but it makes sense to ask whether humans will ever attribute mind to artifacts. This paper suggests introducing a third level of claims regarding artificial intelligence (AI), which is in between 'weak AI' (...) and 'strong AI', the so-called 'attributed AI'. This level requires more than weak AI ('behave as if', which could be said of any desktop calculator), but is less presumptuous than strong AI ('computers that think', a claim that is hard to prove). Attributed AI can be measured. This paper discusses behavioral paradigms for measurements of attributed AI and presents first experimental data. (shrink)

The Chinese room thought experiment of John Searle militates against strong artificial intelligence, illustrating his claim that syntactical knowledge by itself is neither constitutive nor sufficient for semantic understanding as found in human minds. This thought experiment was put to a behavioural test, concerning the syntax of a finite algebraic field. Input, rules and output were presented with letters instead of numbers. The set of rules was first presented as a table but finally internalized by the participants. Quite in line (...) with Searle's argument, uninformed participants mastered the syntax but did not explicitly report semantic knowledge. In order to test the virtual mind reply to the Chinese room argument, the reaction time pattern of the participants was compared to that of an informed control group. The correlation was quite high but could be traced back to memory load and response priming, i.e. to syntactical factors. No trace of tacit semantic knowledge of the task could be found in the experimental group. (shrink)

This volume presents a series of studies that expand laws, invariants, and principles of psychophysics beyond its classical domain of sensation.
