Background: In this study we used event-related potentials (ERPs) and source localization analyses to track the time course of neural activity underlying response monitoring in children diagnosed with an anxiety disorder compared to age-matched low-risk normal controls. Methods: High-density ERPs were examined following errors on a flanker task…

This paper addresses Lawson's puzzlement about the absence of prediction in William Harvey's and Marcello Malpighi's views on capillaries. In addressing the context of that enquiry, it also addresses historiographic versus philosophical models of science, contexts of discovery versus justification, normative versus descriptive interpretations of…

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…

The present study assessed the compensatory effectiveness of four assistive software tools (speech synthesis, spellchecker, homophone tool, and dictionary) on literacy. Secondary-level students (N = 93) with reading difficulties completed computer-based tests of literacy skills. Training on their respective software followed for those assigned to…

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…

Morphology is one of the organizing principles of the mental lexicon. It is especially important in Hebrew, where word structure expresses a rich array of semantic notions. This study investigated the ability of Hebrew-speaking children to solve written morphological analogies by reading and completing two sets of real and invented root- and…

Language delay and impairment are salient features of autism. More specifically, there is evidence of atypical semantic organization in autism, but the functional brain correlates are not well understood. The current study used functional MRI to examine activation associated with semantic category decision. Ten high-functioning men with autism…

We examined how children with and without oral language (word-finding) difficulties (WFD) perform on oral reading (OR) versus silent reading recognition (SRR) tasks when reading the same words and how lexical factors influenced OR accuracy, error patterns, and nature of miscues. Primary-grade students were administered an experimental reading…

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…
