Conducted study to examine whether practitioners err in administering and scoring Wechsler Adult Intelligence Scale-Revised (WAIS-R). Obtained WAIS-R protocols from 50 randomly selected psychological folders in records of 1 school district. Found that practitioners committed errors on all 50 protocols. Errors on 27 of 50 protocols were sufficient…

Two experiments used error-detection to determine the reason for 3-year olds' perseverative errors on the postswitch phase of the Dimensional Change Card Sort. Results implied that perseveration cannot be attributed to difficulty inhibiting prepotent motor responses, but that changes in rule use between 3 and 5 years are more likely to increase…

In 2 experiments, participants used a keyboard to enter 4-digit numbers presented on a computer monitor under conditions promoting fatigue. In Experiment 1, accuracy of data entry declined but response times improved over time, reflecting an increasing speed-accuracy trade-off. In Experiment 2, the (largely cognitive) time to enter the initial…

Deep dyslexia is an acquired reading disorder that involves the production of semantic errors and the inability to read aloud nonwords successfully. Several explanations for this reading impairment posit multiple loci of damage to account for the various error types produced in deep dyslexia. In contrast, the failure of inhibition hypothesis…

As the entry-level information technology jobs could be easily outsourced offshore, the demand for U.S. employees who are innovative and productive in information technology (IT) project design, development, and management is growing among U.S. companies. This controlled experiment presents how a model of integrating students' intelligence…

To foster medical students' diagnostic knowledge a case-based worked example approach was implemented in the context of a computer-based learning environment. Thirty medical students were randomly assigned to the condition "with erroneous examples", and 31 students learned with correct examples. Diagnostic knowledge was operationalised…

Large corpora such as the British National Corpus and the COBUILD Corpus and Collocations Sampler are now accessible, free of charge, online and can be usefully incorporated into a process writing approach to help develop students' writing skills. This article aims to familiarize readers with these resources and to show how they can be usefully…

When bisecting words in their middle, people reveal leftward bisection errors. This tendency might emerge from an attentional bias towards the beginning of the word. However, when longer meaningless letter strings are presented, people reveal a rightward bisection bias. To test the role of semantic information on leftward or rightward bisection…

The present study examined whether young children's behaviors in the Dimensional Change Card Sorting task can be influenced by their observation of another person performing the task. Experiment 1 showed that after children watched an adult sorting cards according to one rule, although the children were instructed to sort the cards according to a…

Age-appropriate modifications of the A-not-B task were used to examine 2-year-olds' search behavior. Several theories predict that A-not-B errors will increase as a function of number of A trials. However, the hierarchical competing systems model (Marcovitch & Zelazo, 1999) predicts that although the ratio of perseverative to nonperseverative…

The conventional approach for testing the equality of two normal mean vectors is to test first the equality of covariance matrices, and if the equality assumption is tenable, then use the two-sample Hotelling T[superscript 2] test. Otherwise one can use one of the approximate tests for the multivariate Behrens-Fisher problem. In this article, we…

A traditional distance learning system requires supervisors or teachers always available on online to facilitate and monitor a learner's progress by answering questions and guiding users. We presents an English chat room system in which students discuss course contents and ask questions to and receive from teachers and other students. The…

36 Saudi EFL freshmen students took a listening-spelling test in which they filled out 100 blanks in a dialogue. Results indicated that 63% of the spelling errors were phonological and 37% were orthographic. It was also found that the subjects had more phonological problems with whole words but more orthographic problems with graphemes. Some of…

The detection of errors is known to be associated with two successive neurophysiological components in EEG, with an early time-course following motor execution: the error-related negativity (ERN/Ne) and late positivity (Pe). The exact cognitive and physiological processes contributing to these two EEG components, as well as their functional…

This article is based on results of a quasi-experimental study in which the efficacy of the strategies approach for reviewing grammar and punctuation concepts was assessed in a business communication course. The control group studied rules-based review materials; the treatment group studied strategies-based review materials. On the three sets of…
