We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

The statement matching paradigm was used to examine how 10- to 13-year-olds categorized adults when both ethnicity and gender varied across targets. Forty-seven children watched a PowerPoint presentation of a conversation involving two Black men, two Black women, two White men and two White women. Each slide displayed the speaker's picture, name…

This study examined the reading accuracy of dyslexic readers in comparison to chronological age-matched normally progressing readers in Hindi and English using word reading tasks, matched for spoken frequency of usage, age of acquisition, imageability, and word length. Both groups showed significantly greater reading accuracy in Hindi than in…

Idea evaluation is a critical aspect of creative thought. However, a number of errors might occur in the evaluation of new ideas. One error commonly observed is the tendency to underestimate the originality of truly novel ideas. In the present study, an attempt was made to assess whether analysis of the process leading to the idea generation and…

This article reports the results of speech error elicitation experiments investigating the role of two consonant co-occurrence restrictions in the productive grammar of speakers of two Ethiopian Semitic languages, Amharic and Chaha. Higher error rates were found with consonant combinations that violated co-occurrence constraints than with those…

Pavlovian fear learning depends on predictive error, so that fear learning occurs when the actual outcome of a conditioning trial exceeds the expected outcome. Previous research has shown that opioid receptors, including [mu]-opioid receptors in the ventrolateral quadrant of the midbrain periaqueductal gray (vlPAG), mediate such predictive fear…

After examining literature that deals with phonological and orthographic effects associated with pseudohomophones, the current effort deviates from the norm by using fewer pseudohomophones (20) and extending the lags between primes and targets (M=8). Word and pseudohomophone primes were found to facilitate lexical decision response latencies to…

In this article, I present a longitudinal study of a child's (male, aged 3;0-3;4) acquisition of intervocalic consonants characterized within the framework of Optimality Theory (OT). At Stage I, the child presents with unusual error patterns, weakening and labial substitution, and shows evidence of phonologically opaque surface forms. These…

Identifying the approach used by those revision experts par excellence--that is, professional editors--should enable researchers to better grasp the revision process. To further explore this hypothesis, the author conducted research among professional editors, six of whom she filmed as they engaged in their practice. An analysis of their work…

This report examines the causes of error in two techniques for measuring eye fixation position. Theoretical calculations of the magnitude of sources of error are shown to produce good agreement with empirically derived magnitudes for adult and neonate eyes.

Spelling error analysis performed on 27 dyslexic fourth to eighth graders and 27 normal second graders revealed no significant differences in phonetic accuracy, level of maturity, or incidence of serial order confusion. Findings did not support prevailing approaches characterizing dyslexic students as phonetically inaccurate spellers. (CL)

Describes system design proposed by the Spelling Error Detection Correction Project (SPEEDCOP) at Chemical Abstracts Service. Highlights include principles of detection/correction system; spelling error detection (the dictionary, suffix normalization, bypassing specialized word classes, document-level frequency threshold); spelling error…

Iterative Intercolumnar Correlation Classification (IICC) computes the correlation coefficients for the entries of every column of a matrix with those of every other column of the matrix. Iteration increases the size and validity of the object indices, reduces error in the indices, and increases homogeneity amongst them. (Author/BW)

The article presents techniques for error analysis and correction for use with handicapped children. Considered are error and trend analysis, corrective feedback, graduated guidance hierarchy, errors as part of the learning process, the teacher's verbal correction, and oral reading correction procedurs.
