Emergence of epistemic phenomena (poster)

Leibovitz, D. P. (2012) Emergence of epistemic phenomena. Poster presented at the Institute of Cognitive Science Spring Conference (ICSSC) of Carleton University, pp. 1-12. Ottawa, Ontario, Canada[doi10.13140/RG.2.1.4649.3920] (PDF)

Leibovitz (2012) Emergence of Epistemic Phenomena (ICSSC Poster)Abstract: Q: Are you using the correct level of analysis?

We claim that for the unique requirements of cognition

  1. There is only one micro level of ontology, realization and causal explanation (the systems level)
    1. It is process oriented
    2. It can causally explain all higher level behaviours and phenomena
  2. There are no higher levels of causal explanation
    1. Causality flows among actual ontological parts, not to or from epistemic abstractions Under the standard macro level approach, we further claim that
  3. There are no macro level stimuli, measurements and phenomena – they are epistemic illusions
    1. Merely arbitrary and uninformed patterns of micro-level inputs or outputs between an experimental paradigm and a non-representational cognitive agent

Our claims originate from our unified process model of visual filling-in. We noticed that while the model explains all the phenomena, none of them actually existed. The epistemic phenomena arise from oversimplified and implicit folk-theories. Epistemic phenomena emerge from lack of knowledge, from lack of a Systems level theory.

We show the results – the visual demonstration for a variety of “phenomena”. Your task:

Show me the macro level stimuli, measurement or phenomena!

It is only by getting rid of the macro level of analysis that one can hope to uncover a (micro) systems level and begin to causally unify explanations for cognition.

Emergence in the Mind’s Eye (talk)

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

Local Measure Reliability vs. Global Concept Validity. Has Cognitive Science Moved Beyond Behaviourism? (Insignificant Progress in Validating Cognitive Constructs p<.05)

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. [doi10.13140/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.

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 :).

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. [doi10.13140/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?
