Rater errors (rater severity, halo effect, central tendency, and restriction of range) are described, and criteria are presented for evaluating rating quality based on a many-faceted Rasch (FACETS) model. Ratings of 264 compositions from the Eighth Grade Writing Test in Georgia by 15 raters illustrate the discussion. (SLD)

This article reanalyzes the principle of partial participation in integrated educational programing for students with severe or profound disabilities. The article presents four "error patterns" in how the concept has been used, some reasons why such error patterns have occurred, and strategies for avoiding these errors. (Author/JDD)

Reports on experiments where Arabic-speaking subjects were asked to scan arrays of digits in both standard "Western numeral" and "Indian numeral" forms, and compares array-scanning patterns observed with patterns observed with speakers of other languages, particularly English. The implications in terms of the use of…

Studies in 1974 and 1984 of errors in the writing of Australian university freshmen in a history course found no significant differences between the two groups. The most salient elements in the error-prone writing were less related to writing mechanics than to constitution of meaning, suggesting that grammar instruction is inadequate to improve…

Article discusses research on orientation and mobility (O&M) for individuals with visual impairments, examining constant, variable, and absolute error (descriptive statistics that quantify fundamentally different characteristics of distributions of spatially directed behavior). It illustrates the statistics with examples, noting their…

The study examined word recognition abilities of readers at instructional and frustrational reading levels with 32 learning-disabled readers in grades 2, 5, 8, and 11. Findings indicated that only in the category of linguistic acceptability (syntactic and semantic) did readers produce significantly fewer acceptable responses when reading…

Aims at demonstrating the gradual automatization of subject-verb agreement operation in young writers by examining developmental changes in the occurrence of agreement errors. Finds that subjects' performance moved from systematic errors to attraction errors through an intermediate phase. Concludes that attraction errors are a byproduct of the…

Analysis of the first 4 months of word combinations recorded for an Estonian-English learning child suggests that meaning-based generativity may play a role in this important transition in that mixed language utterances, sequence reversals, and errors revealing early attempts at analysis provide clear evidence that distributional learning alone…

Outlines a psycholinguistic model of vocabulary acquisition in a second language in an instructional setting. The model is based on an understanding of the representational characteristics of the second language lexicon. (Author/VWL)

This study investigated acquisition of music performance skills over 11 practice trials in novice and expert pianists differing in age, training, and sight-reading ability. The finding of a strong positive relationship between the mastery of temporal constraints and planning abilities within performance suggested that these two cognitive…

Suggests another perspective in viewing the effect of style on English-as-a-foreign-language learners' errors. Suggests that for consonant clusters, what varies in accordance with style is the learners' choice of syllable simplification strategies rather than error rates. (Author/VWL)

One English-as-a-Second-language teacher talks about the email messages she receives from her students, often filled with symbols and spelling and punctuation errors. Examines why such high-level, hardworking students write this way. (Author/VWL)

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…
