Imaginal perspective switches are often considered to be difficult, because they call for additional cognitive transformations of object coordinates (transformation hypothesis). Recent research suggests that problems can also result from conflicts between incompatible sensorimotor and cognitive object location codes during response specification…

Two experiments examined possible negative transfer in nonexperts from the use of pictorial examples in a laboratory design problem-solving situation. In Experiment 1, 89 participants were instructed to "think aloud" and were assigned to 1 of 3 conditions: (a) control (standard instructions), (b) fixation (inclusion of a problematic…

This article presents and tests the authors' integration hypothesis of global/local processing, which proposes that at early stages of processing, the identities of global and local units of a hierarchical stimulus are represented separately from information about their respective levels and that, therefore, identity and level information have to…

Perhaps the most "naturally occurring" data on school misbehavior and aggression are school discipline data, including office referrals, suspensions, and expulsion data. These data constitute the most common markers of school discipline status available on school campuses. There is, however, very little information available in professional or…

We present morphological analyses of verb inflections produced by 15 Spanish-speaking children (age range: 1;7 to 4;7) taken from longitudinal and cross-sectional samples of spontaneous speech and narratives. Our main observation is the existence of a dissociation between regular and irregular processes in the distribution of errors: regular…

Three experiments investigated the ability of eight-year old children with poor language comprehension to produce past tense forms of verbs. Twenty children selected as poor comprehenders were compared to 20 age-matched control children. Although the poor comprehenders performed less well than controls on a range of tasks considered to tap…

This article presents a framework for the cognitive diagnosis of learners' errors in an interactive learning activity occurring in an intelligent learning environment. The proposed framework supports the implementation of an authoring tool. This tool helps instructional designers to specify the features of a component for cognitive diagnosis. Two…

The guide to "false friends," or false cognates, in German and English is designed such that it can be used as either an instructional tool or a reference guide. An introductory section defines false friends and discusses different types, and provides a set of symbols for distinguishing them. The first major section lists, alphabetically…

The second guide to "false friends," or false cognates, in German and English lists and discusses more difficult terms than the first guide. An introductory section defines false friends and discusses different types, and provides a set of symbols for distinguishing them. The first major section lists, alphabetically in German, and…

An exercise in the evaluation of errors in Spanish (second language) composition is reported. The exercise, based on J. M. Hendrickson's "discovery" approach to learning, concerned correction of three error types: lexicon; grammar; and spelling. Subjects were 13 native English-speaking university students in a Spanish language program. In the…

This manual is a dictionary of some 150 errors made by students in their work in mathematics. A precise definition and examples are given for each of these errors and these, combined with a description of common causes of the error, form a background for diagnosis of student problems with arithmetic. Teaching strategies and ideas, each linked to a…

An analysis of two French-English business dictionaries, a 1989 revised edition and a 1990 edition, looks at a number of weaknesses in the resources' design and content. First, problems are found in transcriptions of pronunciation that do not reflect actual usage when it differs from convention and in lack of attention to pronunciation of words…

While mail surveys offer an efficient and cost effective means of gathering large amounts of student-related data in a relatively short time, surveys characterized by low response rates may have a biasing effect on information. To examine this bias, a study was undertaken of the characteristics associated with samples from three graduate follow-up…

A study of children's acquisition of the auxiliary verb system in English is reported. The first section describes the operation of the auxiliary system, and proposes that the behavior of auxiliaries is so complicated that if children were to generalize from one auxiliary to another, they would make predictable errors. The second section reviews…

A study investigated the appropriate use and interpretation of a phonological test, the Computer Analysis of Phonological Processes (CAPP), with children who are not speakers of Standard English. In the test, three-dimensional objects are used to elicit spontaneously a carefully designed word list including all American English phonemes and 31…
