This study evaluated an experimental articulation testing instrument for differentiating child speakers (N=21, ages 5:0 to 6:6) of African-American Vernacular English (AAVE) with atypical and typical phonologies. Significant group differences were observed, suggesting that the measure can differentiate typical and atypical development in this…

Discusses the significance of causation/reasoning patterns in Korean. Presents crucial examples of acquisition errors of the patterns collected from students learning Korean as a foreign language and proposes an alternative explanation and analysis of these patterns.(Author/VWL)

Examined developmental changes in time estimation among 5- to 99-year olds. Found that older adults and young children performed at lower levels than young adults; identified qualitative differences in error patterns of older adults and children. Proposed model of temporal generalization and bisection assuming developmental changes in noisiness of…

Examined whether a detailed analysis of age-related changes in error patterns could reveal the mechanisms underpinning development in short-term memory. Tested developmental changes among 7- to 11-year-olds in their serial recall of lists of 6 letters, finding developmental differences in the patterns of errors. (JPB)

Addresses the lack of data on procedures used to recruit subjects in marital research by examining the effects of different sampling techniques. In Study One, couples recruited through newspaper advertisements were found to be at greater risk for marital discord. In Study Two, couples who responded to mailed solicitation were found to be less…

First-language attrition and loss of noun-phrase gender agreement were studied for 22 months with two Puerto Rican sisters, beginning at ages 6.6 and 4.6 years. Analysis of taped mother-child conversations suggests that Spanish gender agreement morphology is vulnerable to language loss. Subjects' gender errors were related to their language…

Weak English-as-a-foreign-language students adopt several mistaken strategies to understand text or to perform text-based tasks. This article describes mistaken strategies, provides examples of each, explains the cause or causes of such mistaken approaches, and suggests possible solutions. (Author/VWL)

This article proposes a new approach to the statistical analysis of pairwisepresent covariance structure data. The estimator is based on maximizing the complete data likelihood function, and the associated test statistic and standard errors are corrected for misspecification using Satorra-Bentler corrections. A Monte Carlo study was conducted to…

We investigated expectations regarding a writer's responsibility to proofread text for spelling errors when using a word processor. Undergraduate students read an essay and completed a questionnaire regarding their perceptions of the author and the quality of the essay. They then manipulated type of spelling error (no error, homophone error,…

Students completing a time calculation exercise identified the International Date Line (IDL) as a conceptual source of confusion and poor performance. From the early 1950s to the present, various geography textbooks have promulgated misstatements involving the occurrence of midnight at the IDL. This condition's persistence and ubiquity manifests a…

Many current generativist theorists suggest that young children possess the grammatical principles of inversion required for question formation but make errors because they find it difficult to learn language-specific rules about how inversion applies. The present study analyzed longitudinal spontaneous sampled data from twelve 2-3-year-old…

Although there is extensive documentation of the morphological limitations of children with specific language impairment (SLI), few studies have reported on complex syntax acquisition in children with SLI. This case study examined the development of complex syntax in a child with SLI between 3 and 7 years. Twelve conversational samples were…

Previous research has shown that short-term memory for serial order can be influenced by background knowledge concerning regularities of sequential structure. Specifically, it has been shown that recall is superior for sequences that fit well with familiar sequencing constraints. The authors report a corresponding effect pertaining to serial…

The person-response function (PRF) relates the probability of an individual's correct answer to the difficulty of items measuring the same latent trait. Local deviations of the observed PRF from the expected PRF indicate person misfit. We discuss two new approaches to investigate person fit. The first approach uses kernel smoothing to estimate…

This study examined word identification skills among Chinese and Korean college students learning to read English as a second language in a naming experiment and an auditory category judgment task. Both groups demonstrated faster and more accurate naming performance on high-frequency words than low-frequency words and on regular words than…
