  • The limited capacity of working memory is intrinsic to human sentence processing, and therefore must be addressed by any theory of human sentence processing. This paper gives a theory of garden-path effects and processing overload that is based on simple assumptions about human short term memory capacity. hypothesis, is easily compatible with the above view of processing load calculation: given a choice between two different representations for the same input string, simply choose the representation that is associated with the lower processing load. ...

  • Among the components of the limbic system, the amygdala is a fascinating structure that is involved in the processes of liking and disliking and in the ways our emotions drive our actions and affect the strength of our memories. Combined with new conceptual breakthroughs, the very latest data obtained by leading world experts in amygdala function that are reviewed in this book have helped to understand how the amygdala contribute to these processes and also to a variety of neurological and neuropsychiatric pathologies....

  • Conduction Aphasia Speech output is fluent but paraphasic, comprehension of spoken language is intact, and repetition is severely impaired. Naming and writing are also impaired. Reading aloud is impaired, but reading comprehension is preserved. The lesion sites spare Broca's and Wernicke's areas but may induce a functional disconnection between the two so that lexical representations formed in Wernicke's area and adjacent regions cannot be conveyed to Broca's area for assembly into corresponding articulatory patterns.

  • Language allows the communication and elaboration of thoughts and experiences by linking them to arbitrary symbols known as words. The neural substrate of language is composed of a distributed network centered in the perisylvian region of the left hemisphere. The posterior pole of this network is located at the temporoparietal junction and includes a region known as Wernicke's area. An essential function of Wernicke's area is to transform sensory inputs into their lexical representations so that these can establish the distributed associations that give the word its meaning. ...

  • The Parietofrontal Network for Spatial Orientation: Neglect and Related Conditions Hemispatial Neglect Adaptive orientation to significant events within the extrapersonal space is subserved by a large-scale network containing three major cortical components. The cingulate cortex provides access to a limbic-motivational mapping of the extrapersonal space, the posterior parietal cortex to a sensorimotor representation of salient extrapersonal events, and the frontal eye fields to motor strategies for attentional behaviors (Fig. 27-2).

  • Architecture is those attributes visible to the programmer: Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques. e.g. Is there a multiply instruction? Organization is how features are implemented Control signals, interfaces, memory technology. e.g. Is there a hardware multiply unit or is it done by repeated addition?

  • Finally, interventions that prompt the writer to “read-as-the-reader” explicitly focus working memory resources on the reader representation. These are effective in improving the revising activities of 5th and 9th graders (Holliway & McCutchen, 2004) as well as of college students (Traxler & Gernsbacher, 1993). However, it is unclear from these studies what costs are incurred when limited attention and storage capabilities are focused on the reader representation rather than on the author and text representations.

  • The three stages shown in Figure 1 are intended to demarcate three macro-stages of writing development. Writing skill is shown as continuously improving as a function of practice, as is typical for perceptual-motor and cognitive skills in general. The micro- changes underlying the gradual improvement that drive the transition to the next macro-stage fall beyond the scope of the present article.

  • Amazing! You’re actually reading this. That puts you into one of three categories: a student who is being forced to read this stuff for a class, someone who picked up this book by accident (probably because you have yet to be indoctrinated by the world at large), or one of the few who actually have an interest in learning assembly language.

  • The book presents several advances in different research areas related to data storage, from the design of a hierarchical memory subsystem in embedded signal processing systems for data-intensive applications, through data representation in flash memories, data recording and retrieval in conventional optical data storage systems and the more recent holographic systems, to applications in medicine requiring massive image databases.

  • In the most advanced stage of knowledge-crafting, the writer is able to hold in mind the author’s ideas, the words of the text itself, and the imagined reader’s interpretation of the text. The representations of the author, the text, and the reader must be held in the storage components of working memory and kept active by allocating attention to them (Traxler & Gernsbacher, 1993). Thus, for expert writers, not only are the basic processes of planning, sentence generation, and reviewing juggled successfully, but so are three alternative representations of content.

  • According to Bonfand, it is this principle of imprint which drives a large part of Godard’s system of representation, particularly in the intuitive and memory-based principle which leads the heterogeneity of his juxtapositions and collages of images starting from Pierrot le fou (1965). He demonstrates that Godard considers the canvas of the cinematic screen as ‘a sensible surface, a supporting beam in which something imprints itself […]’ (222).

  • This paper reports the on-going research of a thesis project investigating a computational model of early language acquisition. The model discovers word-like units from crossmodal input data and builds continuously evolving internal representations within a cognitive model of memory. Current cognitive theories suggest that young infants employ general statistical mechanisms that exploit the statistical regularities within their environment to acquire language skills.

  •  Compression of executable code in embedded microprocessor systems, used in the past mainly to reduce the memory footprint of embedded software, is gaining interest for the potential reduction in memory bus traffic and power consumption. We propose three new schemes for code compression, based on the concepts of static (using the static representation of the executable) and dynamic (using program execution traces) entropy and compare them with a state-of-the-art compression scheme, IBM’s CodePack.

  • The romance of history pertains to no human annals more strikingly than to the early settlement of Virginia. The mind of the reader at once reverts to the names of Raleigh, Smith, and Pocahontas. The traveller's memory pictures in a moment the ivy-mantled ruin of old Jamestown. About the year 16--, the city of Jamestown, then the capital of Virginia, was by no means an unapt representation of the British metropolis; both being torn by contending factions, and alternately subjected to the sway of the Roundheads and Royalists.

  • We describe a case study in which a memory-based learning algorithm is trained to simultaneously chunk sentences and assign grammatical function tags to these chunks. We compare the algorithm’s performance on this parsing task with varying training set sizes (yielding learning curves) and different input representations. In particular we compare input consisting of words only, a variant that includes word form information for lowfrequency words, gold-standard POS only, and combinations of these. ...

  • The third stage characterizes the progression to professional expertise in writing. The writer must maintain and manipulate in working memory a representation of the text that might be constructed by an imagined reader as well as the author and text representations. Notice that this stage now involves modeling not just the reader's view of the writer's message but also the reader's interpretation of the text itself. In knowledge-crafting, the writer shapes what to say and how to say it with the potential reader fully in mind.
