Any theory of information processing must address both what is processed and how that processing takes place. Most studies investigating variables which alter physical dimension utilization have ignored the large individual differences in selective attention or cue utilization. A paradigm was developed using an individual focus on information…

In 2 experiments, the authors tested whether the classical modality effect--that is, the stronger recency effect for auditory items relative to visual items--can be extended to the spatial domain. An order reconstruction task was undertaken with four types of material: visual-spatial, auditory-spatial, visual-verbal, and auditory-verbal.…

The Wernicke-Lichtheim-Geschwind (WLG) theory of the neurobiological basis of language is of great historical importance, and it continues to exert a substantial influence on most contemporary theories of language in spite of its widely recognized limitations. Here, we suggest that neurobiologically grounded computational models based on the WLG…

Discussion of the roles of the instructional design specialist (IDS) and the subject matter expert (SME) in designing effective instruction for a training program focuses on the role of the SME. Characteristics of four consulting models are described, and stages of the SME/IDS relationship are summarized. (LRW)

Discusses evaluation models based on the "Kernal of Truth Theory" or Metaperceptual Congruence Methodology. Relates this model to the decision-making process and to the development of ethnic stereotypes. (RB)

A model for analysis of eight different consultant roles, ranging from "directive" to "nondirective" on a continuum, is presented. Defining the scope and focus of responsibility of a consultation, utilizing consulting resources, and a sample of a questionnaire on faculty advising are discussed. (MLW)

Presents study designed to further evaluate the nature of spoken-language comprehension under conditions of varying perceptual load by manipulating different comprehension conditions. Investigates effects of subsidiary task paradigms on course of simultaneous comprehension processing. Argues that these can only be used when accompanied with probes…

Develops a new model of crisis perception and compares it to Hermann's three-variable model (surprise, short decision time, and threat to valued goals). Three specific predictions derived from the proposed model are confirmed by data from 177 industrial and educational organizations that experienced curtailments of natural gas allocations.…

A connectionist model, SEarch via Recursive Rejection (SERR), is presented that performs across a window defining the model's functional field. Implications are discussed, and results of 5 experiments involving 19 male and 19 female adults and adolescents that test novel predictions derived from the model are presented. (SLD)

Presents a four-part theoretical treatment of the planning of speech movements that favors models in which the only invariant targets are regions in auditory perceptual space over models that posit invariant construction targets. Computer simulations illustrate the models. (SLD)

We present a computational model that learns a coupling between motor parameters and their sensory consequences in vocal production during a babbling phase. Based on the coupling, preferred motor parameters and prototypically perceived sounds develop concurrently. Exposure to an ambient language modifies perception to coincide with the sounds from…

A long-standing issue in the study of how people acquire visual information centers around the scheduling and deployment of attentional resources: Is the process serial, or is it parallel? A substantial empirical effort has been dedicated to resolving this issue. However, the results remain largely inconclusive because the methodologies that have…

A biologically detailed computational model is described of how categorization judgments become automatic in tasks that depend on procedural learning. The model assumes 2 neural pathways from sensory association cortex to the premotor area that mediates response selection. A longer and slower path projects to the premotor area via the striatum,…

Autism has been associated with atypical face and configural processing, as indicated by the lack of a face inversion effect (better recognition of upright than inverted faces). We investigated whether such atypical processing was restricted to the face or extended to social information found in body postures. An inversion paradigm compared…
