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.

Conducted study to examine whether practitioners err in administering and scoring Wechsler Adult Intelligence Scale-Revised (WAIS-R). Obtained WAIS-R protocols from 50 randomly selected psychological folders in records of 1 school district. Found that practitioners committed errors on all 50 protocols. Errors on 27 of 50 protocols were sufficient…

Two experiments used error-detection to determine the reason for 3-year olds' perseverative errors on the postswitch phase of the Dimensional Change Card Sort. Results implied that perseveration cannot be attributed to difficulty inhibiting prepotent motor responses, but that changes in rule use between 3 and 5 years are more likely to increase…

In 2 experiments, participants used a keyboard to enter 4-digit numbers presented on a computer monitor under conditions promoting fatigue. In Experiment 1, accuracy of data entry declined but response times improved over time, reflecting an increasing speed-accuracy trade-off. In Experiment 2, the (largely cognitive) time to enter the initial…

Deep dyslexia is an acquired reading disorder that involves the production of semantic errors and the inability to read aloud nonwords successfully. Several explanations for this reading impairment posit multiple loci of damage to account for the various error types produced in deep dyslexia. In contrast, the failure of inhibition hypothesis…

Background: The profiles of children with Specific Language Impairment (SLI) differ greatly according to the language they speak. The Surface Hypothesis attempts to explain these differences through the theory that children with SLI will incorrectly produce elements in their language with low phonological weights or that are produced in a…

In the past, the nature of the compositional units proposed for spoken language has largely diverged from the types of control units pursued in the domains of other skilled motor tasks. A classic source of evidence as to the units structuring speech has been patterns observed in speech errors--"slips of the tongue". The present study reports, for…

Although structural equation modeling (SEM) is one of the most comprehensive and flexible approaches to data analysis currently available, it is nonetheless prone to researcher misuse and misconceptions. This article offers a brief overview of the unique capabilities of SEM and discusses common sources of user error in drawing conclusions from…

Previous studies have reported working memory deficits in autism, but this finding has been inconsistent. One possibility is that deficits in this domain may be present only when working memory load exceeds some limited capacity. High-functioning individuals with autism performed the CANTAB computerized test of spatial working memory. Individuals…

The goal-directed theory of imitation (GOADI) states that copying of action outcomes (e.g., turning a light switch) takes priority over imitation of the means by which those outcomes are achieved (e.g., choice of effector or grip). The object [fewer than] effector [fewer than] grip error pattern in the pen-and-cups task provides strong support for…

This paper investigates stress assignment in Dutch aphasic patients in non-word repetition, as well as in real-word and non-word reading. Performance on the non-word reading task was similar for the aphasic patients and the control group, as mainly regular stress was assigned to the targets. However, there were group differences on the real-word…

Teachers all over the world are aware that students struggle with fractional concepts and with elementary algebra. Support for this assertion can be found in a variety of research reports. The National Assessment of Educational Progress (NAEP), a United States report, indicates that students have recurrently demonstrated a lack of proficiency in…

This paper investigates the shared or independent nature of grammatical gender representations in the bilingual mental lexicon and the role word form similarity (as in the case of cognates) plays in these representations. In a translation task from Greek (L1) to German (L2), nouns that had the same gender in both languages were translated faster…
