Layers in the Fabric of Mind: A Critical Review of Cognitive Ontogeny

The essay is critically examines the conceptual problems with the influential modularity model of mind. We shall see that one of the essential characters of modules, namely informational encapsulation, is not only inessential, it ties a knot at a crucial place blocking the solution to the problem of understanding the formation of concepts from percepts (nodes of procedural knowledge). Subsequently I propose that concept formation takes place by modulation of modules leading to cross-representations, which were otherwise prevented by encapsulation. It must be noted that the argument is not against modular architecture, but a variety of an architecture that prevents interaction among modules. This is followed by a brief argument demonstrating that module without modularization, i.e. without developmental history, is impossible. Finally the emerging picture of cognitive development is drawn in the form of the layers in the fabric of mind, with a brief statement of the possible implications

A PROPOSAL TO REFINE CONCEPT MAPPING FOR EFFECTIVE SCIENCE LEARNING

Concept maps are found to be useful in eliciting knowledge, meaningful learning, evaluation of understanding and in studying the nature of changes taking place during cognitive development, particularly in the classroom. Several experts have claimed the effectiveness of this tool for learning science. We agree with the claim, but the effectiveness will improve only if we gradually introduce a certain amount of discipline in constructing the maps. The discipline is warranted, we argue, because science thrives to be an unambiguous and rigorously structured body of knowledge. Since learning science may be seen as a process where a novice is expected to be transformed into an expert, we use the context of learning science for making the proposal. Further, we identify certain anomalies in the evaluation of concept maps, and suggest that the evaluation should be based on semantics of the linking words (relation types) and not on graphical criteria alone.\u

Towards a Model of Life and Cognition

What should be the ontology of the world such that life and cognition are possible? In this essay, I undertake to outline an alternative ontological foundation which makes biological and cognitive phenomena possible. The foundation is built by defining a model, which is presented in the form of a description of a hypothetical but a logically possible world with a defined ontological base. Biology rests today on quite a few not so well connected foundations: molecular biology based on the genetic dogma; evolutionary biology based on neo-Darwinian model; ecology based on systems view; developmental biology by morphogenetic models; connectionist models for neurophysiology and cognitive biology; pervasive teleonomic explanations for the goal-directed behavior across the discipline; etc. Can there be an underlying connecting theme or a model which could make these seemingly disparate domains interconnected? I shall atempt to answer this question. By following the semantic view of scientific theories, I tend to believe that the models employed by the present physical sciences are not rich enough to capture biological (and some of the non-biological) systems. A richer theory that could capture biological reality could also capture physical and chemical phenomena as limiting cases, but not vice versa

Muscularity of Mind: Towards an Explanation of the Transition from Unconscious to Conscious

The title “Muscularity of Mind” indicates the point of view that is argued in this essay. I attempt to trace the roots of higher cognitive abilities to the physiological coupling that exists between neuro-sensory and muscular system. Most of the current discourses on the subject base their studies more on the nervous and sensory dimensions, neglecting the most crucial of all, the role of voluntary muscles in shaping the higher cognitive abilities. I make a claim that emancipation of voluntary muscles from the mandatory biological functions to take on the softer habits during the course of evolution played the crucial role in shaping the higher cognitive abilities. I undertake to explain the transition from procedural to declarative representation by hypothesizing that softer operations that are peculiar to higher cognitive agents in the evolutionary order are rooted in the physiological nexus between neuro-sensory and muscular subsystems of the cognitive agent. The objective of this essay is to indicate that the problem cannot be solved without attending to this nexus

Understanding Science Through Knowledge Organizers: An Introduction

We propose, in this paper, a teaching program based on a grammar of scientific language borrowed mostly from the area of knowledge representation in computer science and logic. The paper introduces an operationizable framework for understanding knowledge using knowledge representation (KR) methodology. We start with organizing concepts based on their cognitive function, followed by assigning valid and authentic semantic relations to the concepts. We propose that in science education, students can understand better if they organize their knowledge using the KR principles. The process, we claim, can help them to align their conceptual framework with that of experts which we assume is the goal of science education

The Role of Inversion in the Genesis, Development and the Structure of Scientific Knowledge

The main thrust of the argument of this thesis is to show the possibility of articulating a method of construction or of synthesis--as against the most common method of analysis or division--which has always been (so we shall argue) a necessary component of scientific theorization. This method will be shown to be based on a fundamental synthetic logical relation of thought, that we shall call inversion--to be understood as a species of logical opposition, and as one of the basic monadic logical operators. Thus the major objective of this thesis is to This thesis can be viewed as a response to Larry Laudan's challenge, which is based on the claim that ``the case has yet to be made that the rules governing the techniques whereby theories are invented (if any such rules there be) are the sorts of things that philosophers should claim any interest in or competence at.'' The challenge itself would be to show that the logic of discovery (if at all formulatable) performs the epistemological role of the justification of scientific theories. We propose to meet this challenge head on: a) by suggesting precisely how such a logic would be formulated; b) by demonstrating its epistemological relevance (in the context of justification) and c) by showing that a) and b) can be carried out without sacrificing the fallibilist view of scientific knowledge. OBJECTIVES: We have set three successive objectives: one general, one specific, and one sub-specific, each one related to the other in that very order. (A) The general objective is to indicate the clear possibility of renovating the traditional analytico-synthetic epistemology. By realizing this objective, we attempt to widen the scope of scientific reason or rationality, which for some time now has perniciously been dominated by pure analytic reason alone. In order to achieve this end we need to show specifically that there exists the possibility of articulating a synthetic (constructive) logic/reason, which has been considered by most mainstream thinkers either as not articulatable, or simply non-existent. (B) The second (specific) task is to respond to the challenge of Larry Laudan by demonstrating the possibility of an epistemologically significant generativism. In this context we will argue that this generativism, which is our suggested alternative, and the simplified structuralist and semantic view of scientific theories, mutually reinforce each other to form a single coherent foundation for the renovated analytico-synthetic methodological framework. (C) The third (sub-specific) objective, accordingly, is to show the possibility of articulating a synthetic logic that could guide us in understanding the process of theorization. This is realized by proposing the foundations for developing a logic of inversion, which represents the pattern of synthetic reason in the process of constructing scientific definitions

A Comparative Analysis of Competency Expectations between Tourism Professionals and Tourism Academicians

Education is one of the strongest foundations which enable an individual to develop his competency and skills. Education also helps in making positive contributions towards the creation of wealth and quality of life. Educational institutions transform the life of the individual and also makes him contributeto the welfare of the society and organization he or she works for. The organization looks for those candidates who can contribute to the growth and development of the organization through his or her ability and skills. Education institution has to develop skills and abilities among the students which meet the competency expectations of the organization. The purpose of the study is to investigate whether tourism education meets the competency expectation of the tourism industry. The main objective of this study is to find out the gap between competency expectations of tourism academicians and tourism professionals. The scope of the study covers institutions which offer tourism education in Bangalore, Shimoga, and Mangalore. The study also includes service sectors such as travel agencies and tour operators, hotels and airlines within Bangalore. The targeted respondents of the study are tourism faculty members of institutions and tourism professionals in service organizations. Both primary and secondary data are considered to collect the data. Statistical tools such as correlation, paired sample test are used to analyse the data. The study found that there is a gap that exists between perception of academicians and tourism professionals on the benefit of tourism degrees and also insisted more relevant curriculum that meets the needs of the industry. This study also suggested various measures that would help education institutions to meet the expectations of industry by providing skilled workforce
