In these choice response keyboard tasks, older subjects detected and corrected their errors as efficiently as the young. Reaction time (RT) for error and error correction responses remained relatively constant with increasing age while RTs for correct responses and other, arbitrary, error-signaling responses markedly increased. (Author/SJL)

Seventy percent of the children (non-conservers in length) who had to respond to length equality as opposed to inequality made the correct invariance judgment and could characterize their choices in invariance language, while still failing the standard verbal task in which the experimenter used such phrases. (Author/SJL)

Discusses the theoretical foundations of both basic approaches to contrastive analysis, the predictive, "a priori" version, and the explanatory, "a posteriori" version. Analyzes problems in both approaches, and states that explanatory investigations must be divorced from "classical" contrastive analysis and used with a more realistic methodology…

This report discusses students' understanding of the algebraic concepts of gradient and intercept with respect to simple graphs. A pilot study is described which attempts to identify the difficulties students encounter and determine the number of students who have these difficulties. (MK)

In a study of advanced shorthand students, the following were the most frequent transcription errors: punctuation errors, substitutions, spelling or English usage errors, poor corrections, omission in notes, and incorrectly written figures. Constant reviewing, testing, and drills in these areas were recommended. (CT)

Describes how, through the use of two diagrams, one can teach the English present-perfect to Iranian students. One diagram consists of a time-line divided into "past" and "non-past." The other uses an oval to indicate a time-span including the present. Both facilitate comprehension of present-perfect meaning. (PJM)

Outlines a method for teaching writing encourages self-improvement while downplaying competition. The instrument is a scoring grid which classifies and tabulates errors, then assigns values in each of several pertinent categories, based on the student's performance in that category relative to his classmates. Individual and group evaluation is…

Indicates that a teacher's responses to errors made by students in oral reading are related to that teacher's theoretical orientation as well as to the type of error made. (HOD)

Examines 158 examples of malapropisms and determines three possible sources of this type of error: (1) childhood errors that were never corrected, (2) other kinds of imperfect learning, and (3) breakdown in the storage and retrieval system of the mental lexicon. (AM)

The Guttman scale is discussed from the viewpoint of errors in response patterns. The errors are assumed to be distributed as a binomial. A double-barreled significance test is suggested having two probabilities: high probability and low probability. (Author)

In the experiment reported here, dyslexic children are compared with controls in their processing of single digits. The rationale for the present study relates to a concern to identify if there are specifically unique aspects of how dyslexic children process visual information. (Author)

Describes a research study to determine how teachers actually deal with the whole problem of getting students to proofread their typing and shorthand exercises and projects. (HD)

Errors in naming pictures were studied for 12 children followed from age 15 months to 22 months and for 60 children of similar ages at three different levels of vocabulary development. An increase in naming errors was found with sudden increases in productive vocabulary, suggesting interference from previously retrieved words. (SLD)

The defining of colors is a very subjective topic and results in many misunderstandings, especially in translation from one language to another. The number and significance of color adjectives vary from culture to culture. The goal of this article is to explain the origins of such variations and to discuss examples of common translation errors and…

Discusses the theory that the second-language processing of subordinate clauses and of anaphora is affected by the basic word order of a learners native language. This phenomenon, believed to be a prediction of universal grammar, is explored. (54 references) (Author/VWL)
