Vision, Spiders & Time (talk)

Leibovitz, D. P. (2011) Vision, Spiders & Time. Talk presented at Carleton University, pp. 1-34, Ottawa, Ontario, Canada. [doi10.13140/RG.2.1.4201.9047]

Abstract: How is vision perception related to imagination and planning? What is the role of attention (saccades)? Can smart spiders shed light on human cognition?

  • They have severe engineering restrictions
  • They take a long time to think
  • How does that affect cognition
I will relate spider time to practical matters. Hopefully, you will also come to appreciate spiders as well :).

Plants, Cognition, Time (& Philosophy)

Leibovitz, D. P. (2008) Plants, Cognition, Time (& Philosophy). Talk presented at Carleton University, pp. 1-28, Ottawa, Canada. [doi10.13140/RG.2.1.2470.3209]

Abstract: When plants are viewed under various time and spatial scales, their behaviour can appear quite intelligent. This presentation simply aims at questioning some of the basic terminology used by Philosophers of Mind, and Cognitive Scientists. The goal of the presentation is not to answer the following questions, but to stimulate discussion and reflection.

What do we mean by all the aforementioned terms, and how do we clarify them so that plants are once again relegated to simple stimulus-response systems?

The parting thought is in showing that a trivial stimulus-response system is Turing Complete, so perhaps pointing to individual plant processes and showing that each one alone is a stimulus-response portion might miss the overall system-wide intelligence…
