The jay can access these records and exploit them in diverse computations: computing whether a food item stored in some cache is likely to have decayed; computing a route from one location to another; and so on.
And, secondly, are the beliefs we form directly from the results of computer computations deductively grounded beliefs?
The power of the machines was then extended from the numeric into the symbolic domain where infinite-precision computations performed by computer algebra programs have become an everyday affair.
In our ordinary discourse, we distinguish between physical systems that perform computations, such as computers and calculators, and physical systems that don't, such as rocks.
The cluster-state quantum computer also performs parallel computations, although it is harder to see how we get the final result.
Whereas Stich (1983) accepts that mental processes are computational, but denies that computations are sequences of mental representations, others accept the notion of mental representation, but deny that CTM provides the correct account of mental states and processes.
The Curry-Howard correspondence has made intuitionistic natural deduction part of the computer science curriculum: it gives a computational semantics for intuitionistic logic in which computations, and the executions of programs more generally, are effected through normalization.
If cognition is computation simply because cognitive systems, like everything else, may be seen as performing more or less arbitrary computations over the relevant inputs, then it appears that the computational theory of cognition is both trivial and vacuous.
Quantum computers, which rely on the arcana of quantum mechanics to do many computations in parallel, are a long way from actually being useful.
This argument is based on a development in cognitive and computational neuroscience that might provide a genuine alternative to the representations and computations implicit in folk psychological generalizations.
Last year foundries made about half of all logic chips (the ones that carry out computations, as opposed to memory chips, a more commoditised market).
