Analysis of language samples collected from 110 linguistically normal one- to four-year-olds indicated a direct relationship between chronological age, mean length of utterance, and percent of complex sentences. Analysis of the complex sentences in each sample indicated subcategories for each type of complexity with their own order of acquisition.…

Results indicate that children prefer novel stimuli over stimuli to which they previously have been exposed. (Author)

Three-item orderings and two levels of knowledge of ordering were used to study differences in test results, student's perception of the test's fairness and difficulty, and student's estimation of test performance. No significant order effect was found. (Author/GK)

Proposes formulas for expected true-score measures and reliability of binary items as a function of their Rasch difficulty when the trait (ability) distribution is normal or logistic. Provides an illustrative example for using the proposed formulas. (SLD)

Discusses when one can infer children's use of a rule, the mechanisms underlying the development of rule use, and the relation between understanding and execution. Contrasts relational complexity theory with cognitive complexity and control theory. (Author/KB)

This study examined language and fluency characteristics of single-utterance (SU) and multiple-utterance (MU)conversational turns produced by 15 preschoolers who stutter and 15 nonstuttering peers. Results suggest that MU turns are demanding for young children because they evoke relatively long and complex utterances and that clinicians should…

Strategy use, task performance, and perceptions of difficulty were studied for 34 mildly retarded children and 34 who were not retarded. Results showed that retarded children rated tasks more difficult than nonretarded students and responded less well to brief task training. Metacognitive variables predicted recall performance independently of…

Results of three experiments support the conclusion that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition among children between 14 and 22 months of age. Rather, they indicate the skill of infants in using the mirror as a perceptual tool. (RH)

Tests the effects that many photographers believe color and complexity have on how people process the information in photographs. Finds that images with color and more complex elements were easier to remember, and that complexity did not result in more (reported) mental effort. (SR)

Describes a framework for designing an electronic performance support system (EPSS) that reduces the requirement for more traditional forms of training. An intervention summary table is provided that includes five types of interventions, user access, user type (expert and/or novice), purpose, and difficulty. (Author/LRW)

In this article, the author talks about the texts of Jacques Derrida and Dewey. The texts of Jacques Derrida seem inextricably connected to the word deconstruction, yet, Derrida insists, "The word "deconstruction," like all other words, acquires its value only from its inscription in a chain of possible substitutions." The author argues that…

The Common European Framework of Reference (CEFR) posits six levels of proficiency and defines these largely in relation to empirically derived difficulty estimates based on stakeholder perceptions of what language functions expressed by 'Can-do' statements can be successfully performed at each level. Though also containing much valuable…
