Time Constrained Memory For Reader Based Text Comprehension

Time-constrained Memory

This book tries to answer the question posed by Minsky at the beginning of The Society of Mind: "to explain the mind, we have to show how minds are built from mindless stuff, from parts that are much smaller and simpler than anything we'd considered smart." The author believes that cognition should not be rooted in innate rules and primitives, but rather grounded in human memory. More specifically, he suggests viewing linguistic comprehension as a time-constrained process -- a race for building an interpretation in short term memory. After reviewing existing psychological and computational approaches to text understanding and concluding that they generally rely on self-validating primitives, the author abandons this objectivist and normative approach to meaning and develops a set of requirements for a grounded cognitive architecture. He then goes on to explain how this architecture must avoid all epistemological commitments, be tractable both with respect to space and time, and, most importantly, account for the diachronic and non-deterministic nature of comprehension. In other words, a text may or may not lead to an interpretation for a specific reader, and may be associated with several interpretations over time by one reader. Throughout the remainder of the book, the author demonstrates that rules for all major facets of comprehension -- syntax, reference resolution, quantification, lexical and structural disambiguation, inference and subject matter -- can be expressed in terms of the simple mechanistic computing elements of a massively parallel network modeling memory. These elements, called knowledge units, work in a limited amount of time and have the ability not only to recognize but also to build the structures that make up an interpretation. Designed as a main text for graduate courses, this volume is essential to the fields of cognitive science, artificial intelligence, memory modeling, text understanding, computational linguistics and natural language understanding. Other areas of application are schema-matching, hermeneutics, local connectionism, and text linguistics. With its extensive bibliography, the book is also valuable as supplemental reading for introductory undergraduate courses in cognitive science and computational linguistics.

Fluency and Reading Comprehension in Typical Readers and Dyslexics Readers

Reading involves decoding and comprehension components and, to become efficient, it requires a large number of cognitive and linguistic processes. Among those, the phonological awareness, the alphabetic principle, the decoding, the fluency, the lexical development and the text comprehension development. The reading comprehension is strongly related with the development of vocabulary, oral language, linguistic skills, memory skills and ability to make inferences, and the world experiences of each individual. These processes become important only when the professional needs to deal with students presenting difficulties in learning how to read. The difficulty using the knowledge of conversion rules between grapheme and phoneme to the word reading construction characterizes the dyslexia, which is a specific learning disorder with a neurological source. These difficulties presented by students with dyslexia interfere in their learning process impairing the learning development. Knowing and following the reading development and its processes, as well as obtaining the punctuation of fluency abilities and students comprehension allow us to understand what happens when the student presents difficulties to read. This could help in the identification of learning disabilities and in the development of intervention programs.
