ABSTRACT
The goals of this study were to (a) develop an empirically based model regarding the development of fluent and automatic reading in the early elementary school years and (b) determine whether fluent text-reading skills provided benefits for reading comprehension beyond those accounted for by fluent word decoding. First-, second-, and third-grade children completed a series of reading tasks targeting word and nonword processing, text reading, spelling knowledge, autonomous reading, and reading comprehension. Structural equation modeling was carried out to evaluate how these skills operated together to produce fluent text reading and good comprehension. Evidence supported a simple reading fluency model for the early elementary school years suggesting that fluent word and text reading operate together with autonomous reading to produce good comprehension.
ABSTRACT
BACKGROUND: Despite inadequate empirical validation, sit-to-stand (STS) performance is often used as a proxy measure of lower limb strength among older adults. Furthermore, the relationships between bilateral isokinetic hip, knee, and ankle joint strength and their contributions to STS performances among older adults have not been established. The authors evaluated these relationships on 2 STS tests (5-chair STS test and 30-second chair STS test) in sexagenarian women. METHODS: 47 women (mean age, 64.50 years) performed both STS tests on the same day and bilateral isokinetic (60 degrees/second) hip extensor, hip flexor, knee extensor, knee flexor, ankle plantar flexor, and ankle dorsiflexor strength testing within 7 days after STS testing. Regression analyses were performed using the average weight-adjusted isokinetic hip, knee, and ankle joint strength scores as the independent variables and both STS test scores as the dependent variables. RESULTS: Regression analyses including all 6 leg strength variables explained 48% (p = .0001) and 35% (p = .007) of the variance in 5-chair STS test scores and 30-second chair STS scores, respectively. Ankle plantar flexor, hip flexor, and knee extensor strength were the strongest predictors for both STS tests. CONCLUSIONS: Although ankle plantar flexor, hip flexor, and knee extensor strength play essential roles in performing the STS movement, most STS variance was unexplained, suggesting that important additional variables are also involved in completing the movement.

Prosodic reading, or reading with expression, is considered one of the hallmarks of fluent reading. The major purpose of the study was to learn how reading prosody is related to decoding and reading comprehension skills. Suprasegmental features of oral reading were measured in 2nd- and 3rd-grade children (N = 123) and 24 adults. Reading comprehension and word decoding skills were assessed. Children with faster decoding speed made shorter and less variable intersentential pauses, shorter intrasentential pauses, larger sentence-final fundamental frequency (F(0)) declinations, and better matched the adult prosodic F(0) profile. Two structural equation models found evidence of a relationship between decoding speed and reading prosody as well as decoding speed and comprehension. There was only minimal evidence that prosodic reading was an important mediator of reading comprehension skill.
