Leibovitz (2011) Emergence in the Mind's EyeAbstract: A cognitive model of visual processing will be presented. Two cognitive functions will interact to produce many visual phenomena in the mind’s eye. Then again, emergence itself is an illusion…

Leibovitz, D. P. (2011) Local Measure Reliability vs. Global Concept Validity. Has Cognitive Science Moved Beyond Behaviourism? (Insignificant Progress in Validating Cognitive Constructs p<.05). Poster presented at the Institute of Cognitive Science Spring Conference (ICSSC) of Carleton University, Ottawa, Canada. [doi: 10.13140/RG.2.1.2792.8801]

Zero Progress in CognitionAbstract: Every cognitive experiment contributes to the factual accumulation of raw, stimulus-response behavioural  data. The raw data are factual/indisputable in that 95+% scientists understand and can reproduce the operationalized procedure and measures despite validity and interpretation concerns. Nevertheless, there has been zero factual accumulation of cognitive constructs and interpretations as there is no 95+% agreement nor comprehension in the sea of hypotheticals. Indeed, the signal to noise ratio worsens (entropy increases) with every experiment as new micro-theories are created, rather than a scientific reduction (convergence) to unity.

Leibovitz, D. P. (2011) Vision, Spiders & Time. Talk presented at Carleton University, pp. 1-34, Ottawa, Ontario, Canada. [doi: 10.13140/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 :).

Philosophy Behind the Cognitive Modelling of Virtual Eyeballs (talk)

Leibovitz, D. P. (2011) Philosophy Behind the Cognitive Modelling of Virtual Eyeballs. Talk presented at Carleton University, pp. 1-50, Ottawa, Canada. [doi: 10.13140/RG.2.1.4103.6003]

Abstract: David will demonstrate a virtual eyeball intended to model the Lilac Chaser illusion. In particular, he will talk about the philosophy behind his Emergic Approach to cognitive modelling. Topics may include:

  1. Cutting Nature at her Joints – What kind of Butcher do you want to be?
  2. Tri-Level hypothesis does more harm than good (Marr vs. Simon)
  3. What is a function, computation, behaviour or phenomena?
  4. Unification as constraining the 20 Questions posed to Mother Nature
  5. Emergence
  6. Top-Down Design vs. Bottom-Up Re-engineering

Emergic Approach LogoDavid’s intent is to demonstrate that philosophic considerations can positively influence theory construction. We are all influenced by philosophy – do we want to take charge of our path?
