Describes two experiments which investigated the use of distinctive feature codes in the storage of phonetic encoding information by 6- and 7-year-olds during short term memory tasks. A total of 106 children were presented with 30 lists of consonant-vowel syllables for recall. Data indicate that children encode the consonantal phones into sets of…

Writing samples of 50 learning disabled college students were analyzed for fluency and errors of 14 types: omission of words and/or letters, noun plurals, syntax, subject-verb agreement, verb forms and tense, pronoun reference, shifts in person, fused or spliced sentences, fragments, punctuation, capitalization, usage, spelling, and apostrophe…

An index measuring the degree to which a binary response pattern conforms to some baseline pattern was defined and named the Pattern Conformity Index (PCI). One way of conceptualizing what the PCI measures is the extent to which each individual's particular response pattern contributes to, or detracts from, the overall consistency found in the…

A study examined the error rate of the "University of California Union Catalog Supplement," a 47 volume, computer produced book catalog of the materials cataloged by the nine University of California campuses during the years 1963-67. The study attempted not only to determine the rate and nature of errors, but also to develop a…

One of six summaries of workshop sessions (See TM 000 130), designed to strengthen the evaluation of costly programs and their effects, this handbook presents an analysis of both random and nonrandom sampling errors by application of the Bayesian model. This model attempts to formalize the process and procedures of inference from data through…

Discusses, in the context of library evaluation, the major sources of untrustworthy information and describes what can be done to control them. The emphasis is on assessing the impact of changed operations. (JD)

Nonsense utterances were presented to subjects for immediate recall in order to test two hypotheses: (1) the more complex sounds should be more difficult to recall under memory-taxing conditions; (2) the erroneous recall of a less marked for a more marked sound should occur more frequently than the converse error. (CFM)

The author points out two errors in mathematics: the mistreatment of identities and the belief in randomness. He calls for the development of a core of people dedicated to the detection and correction of such errors found in mathematics and logic. (MN)

Response changes on multiple-choice items tend to improve test scores of elementary school children. (Author/MJB)

A typical school spelling task is analyzed in terms of an information processing model of spelling performance. (Author)

Describes two studies that investigated the editing strategies used by college basic writing students as they corrected sentence-level errors in controlled editing tasks. Indicates that, in both studies, students showed two clearly different editing strategies: a consulting strategy and an intuiting strategy. (JD)

Comparison of 30 learning disabled (LD) children, ages 7 to 13, and controls on a computerized test of attentional skills indicated LD subjects committed more omission errors and responded at a slower rate but did not differ from the controls on commission errors, suggesting inefficient allocation of processing resources rather than attentional…

Analyzes accuracy of Library of Congress cataloging for items with Cataloging in Publication records and items not in that program. Types and frequencies of errors are observed with a separate analysis of significant errors. Recommendations are made for copy cataloging based on the different types of errors found. (Author/EM)

Using Logo to work through a maze is described. Suggested programs to help students learn to debug programs are also included, along with the story of the original "computer bug." (MNS)

The paper stresses the importance of informal assessment of spelling, describing both quantitative and qualitative implications. Stages of word knowledge are reviewed and examples of student errors are cited to illustrate needed instruction. (CL)
