Influence of consonantal context on the reading of vowels: evidence from children

When college students pronounce nonwords, their vowel pronunciations may be affected not only by the consonant that follows the vowel, the coda, but also by the preceding consonant, the onset. We presented the nonwords used by Treiman and colleagues in their 2003 study to a total of 94 first graders, third graders, fifth graders, and high school students to determine when these context influences emerge. According to some theories of reading development, early decoding is characterized by context-free links from graphemes to phonemes. However, we found that even children reading at the first-grade level (6-year-olds) were influenced to some extent by a vowel's context. The effect of context on vowel pronunciation increased in strength up to around the fifth-grade reading level (8- and 9-year-olds), and sensitivity to coda-to-vowel associations emerged no earlier than did sensitivity to onset-to-vowel associations. A connectionist model of reading reproduced this general pattern of increasing context effects as a function of training.     

Statistical patterns in children’s early writing

Many theories of spelling development claim that before children begin to spell phonologically, their spellings are random strings of letters. We evaluated this idea by testing young children (mean age = 4 years 9 months) in Brazil and the United States and selecting a group of prephonological spellers. The spellings of this prephonological group showed a number of patterns that reflected things such as the frequencies of letters and bigrams in children’s language. The prephonological spellers in the two countries produced spellings that differed in some respects, consistent with their exposure to different written languages. We found no evidence for reportedly universal patterns in early spelling such as the idea that children write one letter for each syllable. Overall, our results reveal that early spellings that are not phonological are by no means random or universal and preserve certain patterns in the writing to which children have been exposed.     

Further Experience with the Practice Integration Profile: A Measure of Behavioral Health and Primary Care Integration

Valid measures of behavioral health integration have the potential to enable comparisons of various models of integration, contribute to the overall development of high-quality care, and evaluate outcomes that are strategically aligned with standard improvement efforts. The Practice Integration Profile has proven to discriminate among clinic types and integration efforts. We continued the validation of the measure’s internal consistency, intra-rater consistency, and inter-rater consistency with a separate and larger sample from a broader array of practices. We found that the Practice Integration Profile demonstrated a high level of internal consistency, suggesting empirically sound measurement of independent attributes of integration, and high reliability over time. The Practice Integration Profile provides internally consistent and interpretable results and can serve as both a quality improvement and health services research tool.

     

The Effect of Perceived Advantage and Disadvantage on Performance: The Role of External Efficacy

This experiment examined how perceptions of advantage and disadvantage determine performance in a competitive context. We distinguished between internal and external efficacy, and manipulated external efficacy by inducing perceptions of advantaged or disadvantaged starting positions in a competition, keeping the actual positions equal. The treatment increased the performance of the advantaged party and decreased the performance of the disadvantaged party. In addition, measured external and internal efficacy had qualitatively different effects on performance. The results are explained by the idea that losses loom larger than gains.
