In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the degree of flexibility they offer for anticipatory behavior and put forward a corresponding taxonomy of prospection. The adaptive advantage of any memory system can only lie in what it contributes for future survival. The most flexible is episodic memory, which we suggest is part of a more general faculty of mental time travel that allows us not only (...) to go back in time, but also to foresee, plan, and shape virtually any specific future event. We review comparative studies and find that, in spite of increased research in the area, there is as yet no convincing evidence for mental time travel in nonhuman animals. We submit that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms. A theater metaphor serves as an analogy for the kind of mechanisms required for effective mental time travel. We propose that future research should consider these mechanisms in addition to direct evidence of future-directed action. We maintain that the emergence of mental time travel in evolution was a crucial step towards our current success. (shrink)

En este artículo propongo una variedad de conceptualismo contra la objeción no conceptualista de acuerdo con la cual los enfoques no conceptualistas no serían capaces de explicar apropiadamente la percepción animal. En primer lugar, sintetizo la posición de McDowell sobre las mentes animales. En segundo lugar, señalo algunos problemas conceptuales en ella. En tercer lugar, sugiero una extensión del conceptualismo al reino animal a fin de resolver las inconsistencias de McDowell y de acomodar cierta evidencia empírica acerca de algunas capacidades (...) intelectuales atribuidas a algunos animales. Finalmente, presento dos argumentos para rechazar el no conceptualismo. La posición resultante es una versión mínima o deflacionada de conceptualismo de acuerdo con la cual ciertos animales no humanos son capaces de participar del espacio lógico de las razones aun cuando no sean capaces de justificar sus creencias o acciones.

This paper examines the recent literature on meta-cognitive processes in non-human animals, arguing that in each case the data admit of a simpler, purely first-order, explanation. The topics discussed include the alleged monitoring of states of certainty and uncertainty, the capacity to know whether or not one has perceived something, and the capacity to know whether or not the information needed to solve some problem is stored in memory. The first-order explanations advanced all assume that beliefs and desires come in (...) various different _strengths_, or _degrees_. (shrink)
