This paper discusses and provides some preliminary data on errors in APL programming. Data were obtained by analyzing listings of 148 complete and partial APL sessions collected from student terminal rooms at the University of Alberta. Frequencies of errors for the various error messages are tabulated. The data, however, are limited because they…

The study compared five adult stutterers' and five adult nonstutterers' fluent speech patterns produced during one nonshadowed reading and two speech-shadowing conditions (immediate repetition of a heard message). Among results were that stutterers produced fewer speech production errors than nonstutterers during shadowing conditions. (Author/DB)

Error analysis is proposed as a means to supplement diagnostic techniques with exceptional children. A purpose and definition of error analysis are provided. Also, procedures to use error analysis are explained along with basic guidelines to prevent abuse of error analytic techniques. (Author/CL)

A method of constructing a check digit for nonconventional chemical codes is described. (5 references) (Author)

Analysis of results for 1960, 1965, and 1970, and more recent data presage a growing gap between the projected female labor force and its actual size. (Editor)

The study investigated the degree to which errors of scaling and selection depress the linear relationship and whether the reduction in the magnitude of r differs with the type of error. Results indicated that various scaling errors caused considerable discrepancy in the measurement of underlying relations, but the effect of non-normality was…

The Spelling Error Detection Correction Project completed at Chemical Abstracts Service, which extracted over 50,000 misspellings from approximately 25,000,000 words of scientific and scholarly text, shows that expected incidence of misspelling is 0.2 percent, and most misspellings are "typos," 90 percent of which are unlikely to be…

The speech of five stutterers ranging in age from 3 years, 10 months to 5 years, 7 months was analyzed to determine the types of loci of stutterings. The results related to the hypothesis that early stuttering represents mainly a type of difficulty in either the formulaton or the execution of syntactic units. (Author)

Looked at errors produced by 155 students developing spreadsheets while they were working alone, in groups of two, and in groups of three. Determined that synchronous team spreadsheet development is promising but expensive and does not seem to be a cure-all for spreadsheet errors. (JOW)

Two-year-olds' difficulty with rule execution was examined through one of six tasks: a task assessing knowledge about a series of items, a deductive card sort requiring the use of knowledge to sort items by rules, and four modifications of the card sort. Found that the toddlers performed better on the knowledge task than the other tasks. (MDM)

Reviews research on inductive reasoning errors, including seeing patterns or relationships where none exist, neglecting statistical regression, overgeneralizing unrepresentative data, and drawing conclusions based on incomplete decision matrices. Considers "false consensus effect," through which associations with like-minded people lead one to…

Three experiments examined 3- to 4-year olds' judgments about physical representations which no longer matched their references. Results showed that children tended to misidentify the name of a sticker in a written list to match a change to its referent. Children's incorrect judgments indicated that realist errors to external representations…
