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.
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]
They are made up of nodes or artificial neurons which are arrayed and activated in ways that emulate the behaviors of human memory. 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 ...
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 ...
A 'second wave' connectionist (ANN) model with a hidden layer. Connectionism is an approach to the study of human mental processes and cognition that utilizes mathematical models known as connectionist networks or artificial neural networks. [1] Connectionism has had many "waves" since its beginnings.
McClelland's research showed that 86% of the population are dominant in one, two, or all three of these three types of motivation. His subsequent research, published in the 1977 Harvard Business Review article "Power is the Great Motivator", found that those in top management positions had a high need for power and a low need for affiliation ...
In the 1960s, psychologist David McClelland expanded on Murray's work, focusing on the effects of human needs in a work environment. [2] His need theory proposes that most people are consistently motivated by one of three basic desires: the need for affiliation, the need for achievement, or the need for power.
