The WSE has proven to be an important finding for word recognition models, and specifically is supported by Rumelhart and McClelland's interactive-activation model of word recognition. According to this model, when a reader is presented with a word, each letter in parallel will either stimulate or inhibit different feature detectors (e.g. a ...
The IAC model is used by the parallel distributed processing (PDP) Group and is associated with James L. McClelland and David E. Rumelhart; it is described in detail in their book Explorations in Parallel Distributed Processing: A Handbook of Models, Programs, and Exercises. [1]
The second wave blossomed in the late 1980s, following a 1987 book about Parallel Distributed Processing by James L. McClelland, David E. Rumelhart et al., which introduced a couple of improvements to the simple perceptron idea, such as intermediate processors (now known as "hidden layers") alongside input and output units, and used a sigmoid ...
McClelland present work focuses on learning, memory processes, and psycholinguistics, still within the framework of connectionist models. He is a former chair of the Rumelhart Prize committee, having collaborated with Rumelhart for many years, and himself received the award in 2010 at the Cognitive Science Society Annual Conference in Portland ...
TRACE is a connectionist model of speech perception, proposed by James McClelland and Jeffrey Elman in 1986. [1] It is based on a structure called "the TRACE", a dynamic processing structure made up of a network of units, which performs as the system's working memory as well as the perceptual processing mechanism. [2]
According to Rumelhart, the PDP model represents information processing as interactions between elements called units, with the interactions being either excitatory or inhibitory in nature. [8] Parallel Distributed Processing Models are neurally inspired, emulating the organisational structure of nervous systems of living organisms. [9]
Models of visual discrimination of individual letters include those of Gibson (1969), Briggs and Hocevar (1975), and McClelland and Rumelhart (1981), the last of which is part of a larger model for word recognition noted for its explanation of the word superiority effect. These models are noted to be highly detailed, and make quantitative ...
David Everett Rumelhart (June 12, 1942 – March 13, 2011) [1] was an American psychologist who made many contributions to the formal analysis of human cognition, working primarily within the frameworks of mathematical psychology, symbolic artificial intelligence, and parallel distributed processing.
