The Emergic Approach (or EA) is a unifying methodology (and discipline) for progressing science based on the mathematical foundation of open-form thinking. Besides formal proof, the ability to unify disparate phenomena within a computational model is demonstrated by the Emergic Cognitive Model that was completely based on the Emergic Approach, while simultaneously enriching it.
A complex version of open-form thinking has successful hardened physics. However, the soft sciences (and philosophy) are replete with closed-form thoughts that in totality present an almost insurmountable barrier to change. Next to this fortress of cards, open-form thinking appears as a farfetched and irrelevant “philosophy” rather than as the standard approach. While it may be philosophizing, it is less for philosophers, and more for theoretical scientists in the soft sciences (especially cognitive science) interested in synthesis.
From 2007 – present, David Pierre Leibovitz developed a unified epistemology, ontology & metaphysics for the analysis, decomposition, synthesis and modeling of complex systems. The empirical philosophizing behind this Emergic Approach (or EA) to unified cognitive modeling is validated by developing a unified cognitive model – the Emergic Cognitive Model (ECM). This research was initially developed at Carleton University.

Emergic Cognitive Model
The Emergic Cognitive Model (or ECM) is a unifying cognitive model that develops genetically, i.e., based on development parameters or modeling DNA. ECM advances a single powerful theory of human cognition for explaining a variety of emergent phenomena described across experimental paradigms and academic disciplines
The unifying model has no free parameters, and its emergent behavior is commensurate with expectations in its developmental differences, as well as its interactions across a variety of environments, stimuli and situations.
Unifying modeling is guided by the principles of the Emergic Approach for progressing science. Thus, ECM is based on the Emergic Network (a computational architecture), is embodied and developed within virtual agents (persons), and situated within environments (worlds) of an Emergic Cognitive System, for non-representational real-time information processing.
Jittering retina of the Emergic Cognitive Model
Currently, the Emergic Cognitive Model supports low-level aspects of dynamic visual processing. It has a biological realistic retina (with a blind spot, a random placement of photoreceptors that grow in size beyond the fovea), and supports eye movement (including jitter) without motion blur, blinking, and object motion.

Abstract: The study of word-length effect concentrated mostly on the accuracy of recalling short and long words in both pure and mixed lists. Previous studies showed that pure long lists were much poorly remembered. Hulme et al. (2004) found that word-length effect could be abolished in mixed lists when the short and long words are alternated. We investigated distinctiveness and found it to be a salient cue for improved correct recall when the list of words has a single distinctive transition. Lists contained three short words following by three long words and vice versa. Surprisingly, in the short-long condition, there was also an improvement in position 3 recall. One of the possible explanations could be the strategic shift of working memory resource.

Abstract: 
Why don’t you hear your own snoring, while your partner does?
A Perceptual Learning and Matching System (PLMS) is hypothesized that pre-attends the auditory scene during sleep with the goal of classifying sounds into the background to be ignored or into the foreground which will cause arousal for further conscious action. It is also active while an individual is awake and is responsible for the automatic acquisition of capabilities such as non-conceptual linguistic components.
In the case of chaotic snoring sounds, the partner’s PLMS cannot detect a pattern and will awaken the partner, while the snorer’s PLMS will correlate the snoring sounds directly with the individual’s own breathing pattern and hence, ignore it.
The main purpose of this investigation is to understand the functional characteristics of PLMS during a sleep paradigm which is not confounded by consciousness nor rationality. PLMS is a hitherto new cognitive system not before studied.
A secondary purpose is to investigate whether the PLMS of the snorer’s partner can be trained to ignore the snoring sounds. Several experiments are proposed to verify this possibility. Partners of snorers may be more affected than the snorers themselves!

Abstract: 
Writing an academic paper may seem like hiking up an unfamiliar mountain without a trail map. The total effort is immense, you don’t know the area, and you may not feel fit enough to handle the stress. There is also a maze of trails: some trails are interesting, some tiresome and some simply leading nowhere. Where should you start, how should you start, and is it possible to leave your own mark?
Here are a few motivational techniques and ideas to get you climbing…

Abstract: To encourage ESL students in their writing by showing them that many of the writing problems they experience are in fact experienced by many native writers as well. To collaborate with the students to come up with some solutions which may help them respond to these problems in future writing assignments. All of this should be interactive with very little ‘lecture style’ teaching.
