Teacher Reported Poverty Effects on Education Participation in a South African District

This study reports on teachers' perceptions of the effects of poverty on education participation in a district in the Eastern Cape Province in South Africa. Participants were 21 teachers (males = 10; females = 11) from seven schools (primary =5, high schools =1, special school =1). Focus group discussions and key informant interviews were used to collect the data. Teachers were of the view that poverty prevented learners and parents (or guardians) from full participation of the education provided by the schools. Poverty had the effects to disempowered both learners and parents as partners in education. It also constrained the quality of teaching.     

Using E-Z Reader to examine the concurrent development of eye-movement control and reading skill

Compared to skilled adult readers, children typically make more fixations that are longer in duration, shorter saccades, and more regressions, thus reading more slowly (Blythe & Joseph, 2011). Recent attempts to understand the reasons for these differences have discovered some similarities (e.g., children and adults target their saccades similarly; Joseph, Liversedge, Blythe, White, & Rayner, 2009) and some differences (e.g., children’s fixation durations are more affected by lexical variables; Blythe, Liversedge, Joseph, White, & Rayner, 2009) that have yet to be explained. In this article, the E-Z Reader model of eye-movement control in reading (Reichle, 2011 and Reichle et al., 1998) is used to simulate various eye-movement phenomena in adults vs. children in order to evaluate hypotheses about the concurrent development of reading skill and eye-movement behavior. These simulations suggest that the primary difference between children and adults is their rate of lexical processing, and that different rates of (post-lexical) language processing may also contribute to some phenomena (e.g., children’s slower detection of semantic anomalies; Joseph et al., 2008). The theoretical implications of this hypothesis are discussed, including possible alternative accounts of these developmental changes, how reading skill and eye movements change across the entire lifespan (e.g., college-aged vs. older readers), and individual differences in reading ability.     

Orthographic contributions to perceived word center

We have a surprising tendency to misperceive the center of visually presented words (). To understand the origin of this bias, four experiments assessed the impact of letter font, letter size, and grapheme-phoneme convergences on perceived stimulus center. Fourteen observers indicated the perceived centers of words, pseudowords, consonant strings, and lines with a mouse cursor. Visual orthographic factors had no effect on perceived word center but grapheme-phoneme convergence did: Observers compensated for strong grapheme-phoneme asymmetries in the letter strings. These findings support the idea that the cognitive representation of words is spatially distorted as a result of lexical access mechanisms.     

Representation and competition in the perception of spoken words

We present data from four experiments using cross-modal priming to examine the effects of competitor environment on lexical activation during the time course of the perception of a spoken word. The research is conducted from the perspective of a distributed model of speech perception and lexical representation, which focuses on activation at the level of lexical content. In this model, the strength of competition between simultaneously active lexical items depends on the degree of coherence between their distributed semantic and phonological representations. Consistent with this model, interference effects are more complete when the purely semantic aspects of these coactive representations are probed (using semantic priming) than when phonological aspects are probed as well (using repetition priming).     

Gradient effects of within-category phonetic variation on lexical access

In order to determine whether small within-category differences in voice onset time (VOT) affect lexical access, eye movements were monitored as participants indicated which of four pictures was named by spoken stimuli that varied along a 0-40 ms VOT continuum. Within-category differences in VOT resulted in gradient increases in fixations to cross-boundary lexical competitors as VOT approached the category boundary. Thus, fine-grained acoustic/phonetic differences are preserved in patterns of lexical activation for competing lexical candidates and could be used to maximize the efficiency of on-line word recognition.     

Counterintuitive cross-linguistic differences: More morphological computation in English than in Finnish

This study investigates the role of derivational morphology in lexical processing in two typologically quite different languages: Finnish and English. While Finnish is a language with an extremely rich morphology, English morphology is relatively poor. Consequently, the role of morphology in storing and processing words would be expected to be greater in Finnish than in English. With a series of visual lexical decision experiments in both languages, we find that the opposite is the case for derivational morphology: for English, parsing of morphological constituents is often required, whereas for Finnish, full-form storage and access seems to be the rule. We try to explain this counterintuitive finding by making an appeal to the lexical-statistical properties of both languages.     

Access to Child and Adolescent Mental Health Services

Adequate access to child and adolescent mental health services for young people in high need populations is an important concern of service systems researchers and program evaluators. We present results of a statewide study of access to community mental health services for eight populations of special concern. The analysis relied exclusively on existing databases in conjunction with innovative statistical techniques to provide comprehensive measures of access to care. Our findings indicate that access to care varied substantially across special populations, although children and adolescents in each of our eight “special populations” had greater access to public mental health services than members of the general population of the state. The interpretation of the findings and directions for future research are discussed.
