Incremental Process

Word knowledge acquisition is an incremental process that relies on exposure. As a result, word knowledge can broadly range from recognizing the word’s lexical status, to knowing its meaning in context, and to knowing its meaning independent of context. The present study aimed to model incremental word knowledge in 1454 upper primary school children from grades 3 to 5 by investigating their abilities on three word knowledge tasks originating from the same set of 300 words: lexical decision, context decision, and definitional decision. A mixed-effects model showed significant differences in performance between tasks and between grades, and a significant interaction indicating that task differences were different for children in grade 5 compared to children in grades 3 and 4. In order to examine further the different task relation patterns at the word level, a cluster analysis was performed using the observed item means, which were corrected for the guessing chance. The analysis showed that for most words, recognition of its lexical status was easier than knowing its meaning in context, which in turn was easier than knowing its meaning independent of context. It is concluded that task relation patterns differ based on mean log frequency as a proxy of word exposure.

This study investigated the developing metalinguistic capabilities of Hispanic primary school children who are becoming bilingual but whose English reading achievement is below average. Two questions were posed: first, do native- and second-language vocabulary and degree of bilingualism contribute to performance on a metalinguistic task (defining words) and, second, do native- and second-language vocabulary and metalinguistic development at the word level significantly predict reading comprehension in the spring? The results showed that performance on the definition task in English and in Spanish was significantly explained by word knowledge in the language of the task; performance on the definition task in the other language (English or Spanish) but not degree of bilingualism contributed significantly, after the effects of vocabulary in the two languages were accounted for. Both native- and second-language vocabulary and phonological awareness independently contributed to achievement in English reading comprehension. The results suggest that, for children with limited native-language development in the early stages of bilingualism, vocabulary development in both the native and second language and metalinguistic development at the word level may be important education priorities because of their effects on second-language reading comprehension.

Multifactorial Approach

AbstractSentence-internal capitalization of nouns is a characteristic of written Standard German. The sixteenth and seventeenth centuries have been identified as the crucial period for the development of this graphemic convention. Previous studies have shown that animacy played a major role in the spread of sentence-internal capitalization. On the basis of the transregional SiGS-corpus consisting of 18 protocols of witch trials (hand-)written between 1588 and 1630, we propose word frequency as an additional factor and test for its interaction with animacy. Our data reveal that the proportion of capitalized words denoting humans and animate concepts increases rapidly, while the capitalization of lexemes referring to concrete and abstract concepts remains stable at a lower level. A binomial mixed-effects model shows a highly significant effect of frequency and a significant interaction between frequency and animacy. In sum, our data show how cognitive, pragmatic, and usage factors conspire in the gradual emergence of a graphemic convention. We therefore argue that the previously neglected graphemic dimension can add important insights to an empirically based theory of the language-cognition interface.

CRA1008 Background: S0221 is a SWOG-coordinated phase III adjuvant chemotherapy intergroup trial in node-positive and high-risk node-negative operable breast cancer which hypothesized that 1) the weekly AC+G regimen is superior to ddAC x 6 and 2) 12 weeks of weekly paclitaxel (wP) is superior to q 2 week paclitaxel x 6 (ddP). Methods: Between December 2003 and November 2010, 2,716 patients were randomized in a 2 x 2 factorial design to 1) AC+G vs ddAC and 2) P 80 mg/m2/week x 12 vs P 175 mg/m2 q 2 weeks x 6. If there was no significant interaction between the factors, the trial was powered to find a disease-free survival hazard ratio (HR) ≤ 0.82 for weekly vs q 2 week for each factor. At the first interim analysis, the AC randomization was halted for futility, and S0221 was closed to accrual 10 November 2010. S0221 reopened 15 December 2010, after which time all patients received 4 cycles of ddAC and randomization to P weekly x 12 and ddP x 6 continued. Accrual halted at a total of 3,294 in January 2012. Results: By September 7, 2012, 487 events and 340 deaths had occurred, prompting the third planned interim analysis. The Data Safety and Monitoring Committee recommended reporting the results since the futility boundary was crossed. A Cox model adjusting for the AC arms had a HR = 1.08 (95% CI 0.90-1.28; p=0.42), with the 99.5% CI excluding the original alternative hypothesis that the HR=0.82. There was no significant interaction of the two factors. Estimated 5-year progression-free survivals were 82% for weekly P and 81% for ddP. Toxicity data were available for 1,385 patients treated with ddP and 1,367 treated with weekly P. Grade 5 toxicity occurred in 4 patients on ddP and 2 on weekly P. Percent grade 3-4 toxicity per arm are shown in the Table. Conclusions: Either ddPx6 or weekly P x 12 are acceptable schedules of P administration. The differences in leukopenia likely reflect ascertainment bias against weekly P. If this is accepted, weekly P x 12 produces less overall toxicity than 6 cycles of ddP.

Abstract Background Self-reported antiretroviral therapy (ART) adherence measures that are associated with plasma viral load (VL) are valuable to clinicians and researchers, but are rarely examined among groups vulnerable to dropping out of care. One-seventh of all those living with HIV pass through incarceration annually and criminal-justice (CJ) involved people living with HIV (PLH) are vulnerable to falling out of care. We examined the association of self-reported ART adherence with VL in a criminal-justice sample compared to a routine-care sample. Methods Samples: We examined data from a multisite collaboration of studies addressing the continuum of HIV care among CjJ involved persons in the Seek, Test, Treat, and Retain cohort. Data pooled from seven CJ- studies (n = 414) were examined and compared with the routine-care sample from the Centers for AIDS Research Network of Integrated Clinical Systems’ seven sites (n = 11,698). Measures: In both samples, data on self-reported percent ART doses taken were collected via the visual analogue scale adherence measure. Viral load data were obtained by blood-draw. Analysis: We examined the associations of adherence with VL in both cohorts using mixed effects linear regression of log-VL, and mixed effects logistic regression of binary VL (≥ 200 copies/mL) outcomes. Interactions by CD4 count and self-reported health status were also tested. Results Among the CJ sample, the coefficient for log-VL was − 0.31 (95% CI = − 0.43, − 0.18; P < 0.01) and that in the routine-care sample was − 0.42 (95% CI = − 0.45, − 0.38; P < 0.01). For the logistic regression of binary detectable VL on 10% increments of adherence we found the coefficient was − 0.26 (95% CI = − 0.37, − 0.14; P < 0.01) and in the routine-care sample it was − 0.38 (95% CI = − 0.41, − 0.35; P < 0.01). There was no significant interaction by CD4 count level in the CJ sample, but there was in the routine-care sample. Conversely, there was a significant interaction by self-reported health status level in the criminal-justice sample, but not in the routine-care sample. Conclusions The visual analogue scale is valid and useful to measure ART adherence, supporting treatment for CJ- involved PLH vulnerable to falling out of care. Research should examine adherence and VL in additional populations.

Four Blocks

The current research utilizes lexical decision within an oddball ERP paradigm to study early lexical processing. Nineteen undergraduate students completed four blocks of the oddball lexical decision task (Nonword targets among Words, Word targets among Nonwords, Word targets among Pseudowords, and Pseudoword targets among Words). We observed a reliable P3 ERP component in conditions where the distinction between rare and frequent trials could be made solely based on lexical status (Words among Nonwords and Nonwords among Words). We saw a reliable P3 to rare words among frequent pseudowords, but no P3 was observed when participants were asked to detect pseudowords in the context of frequent word stimuli. We argue that this observed modulation of the P3 results is consistent with psycholinguistic literature that suggests that two criteria are available during lexical access when performing a lexicality judgement, a non-lexical criterion that relies on global activation at the word level and a lexical criterion that relies on activation of a lexical representation (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001; Grainger & Jacobs, 1996).

Abstract Previous research on the effects of word-level factors on lexical acquisition has shown that frequency and concreteness are most important. Here, we investigate CDI data from 1,030 Dutch children, collected with the short form of the Dutch CDI, to address (i) how word-level factors predict lexical acquisition, once child-level factors are controlled, (ii) whether effects of these word-level factors vary with word class and age, and (iii) whether any interactions with age are due to differences in receptive vocabulary. Mixed-effects regressions yielded effects of frequency and concreteness, but not of word class and phonological factors (e.g., word length, neighborhood density). The effect of frequency was stronger for nouns than predicates. The effects of frequency and concreteness decreased with age, and were not explained by differences in vocabulary knowledge. These findings extend earlier results to Dutch, and indicate that effects of age are not due to increases in vocabulary knowledge.

Reduce Class Size

In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized class size trial with influenza and pneumonia data from the 122 Cities Mortality Reporting System on deaths from pneumonia and influenza. Project STAR was a block-randomized trial that followed 10,816 Tennessee schoolchildren from kindergarten in 1985-86 through third grade in 1988-89. Children were assigned at random to small classes (13 to 17 students), regular-sized classes (22 to 26 students), and regular-sized class with a teachers aide. Mixed effects regression showed that small classes reduced absence, but not necessarily by reducing infection. In particular, small classes reduced absence by 0.43 days/year (95% CI -0.06 to -0.80, p<0.05), but had no significant interaction with pneumonia and influenza mortality (95% CI -0.27 to +0.30, p>0.90). Small classes, by themselves, may not suffice to reduce the spread of viruses.

AbstractPerformance trends in elite butterfly swimmers are well known, but less information is available regarding master butterfly swimmers. We investigated trends in participation, performance and sex differences in 9,606 female and 13,250 male butterfly race times classified into five-year master groups, from 25-29 to 90-94 years, competing in the FINA World Masters Championships between 1986 and 2014. Trends in participation were analyzed using linear regression analysis. Trends in performance changes were investigated using mixed-effects regression analyses with sex, distance and a calendar year as fixed variables. We also considered interaction effects between sex and distance. Participation increased in master swimmers older than ~30-40 years. The men-to-women ratio remained unchanged across calendar years and master groups, but was lower in 200 m compared to 50 m and 100 m. Men were faster than women from 25-29 to 85-89 years (p < 0.05), although not for 90-94 years. Sex and distance showed a significant interaction in all master groups from 25-29 to 90-94 years for 200m (p < 0.05). For 50 m and 100 m, a significant sex × distance interaction was observed from 25-29 to 75-79 years (p < 0.05), but not in the older groups. In 50 m, women reduced the sex difference in master groups 30-34 to 60-64 years (p < 0.05). In 100 m, women decreased the gap to men in master groups 35-39 to 55-59 years (p < 0.05). In 200 m, the sex difference was reduced in master groups 30-34 to 40-44 years (p < 0.05). In summary, women and men improved performance at all distances, women were not slower compared to men in the master group 90-94 years; moreover, women reduced the gap to men between ~30 and ~60 years, although not in younger or older master groups.

This study was done with the aim of assessing the intellectual maturity of children attending typical free primary schools in Ibadan. Human figure drawings produced by 416 boys and 766 girls attending two non-fee paying primary schools were scored using the scoring system introduced by Koppitz. Data analysis shows that intellectual maturity, measured by the scores on the human figure drawings, is significantly related to age. In addition there is a significant interaction between age and sex: girls tend to score higher than boys at certain ages. The findings are discussed in relation to the effects of age, sex and social class, and the use of human figure drawings to measure intellectual maturity.

AbstractThis study investigated the effects of word frequency, collocational frequency, L1 congruency, and L2 proficiency, on L2 collocational processing. Two groups of L1 Japanese speakers of English (intermediate and advanced) and one group of English native speakers (NSs) performed an online acceptability judgment task on four types of adjective-noun constructions: (1) congruent collocations, (2) English-only collocations, (3) Japanese-only collocations, and (4) baseline items. Response times were analyzed using mixed-effects modeling and correlations. In contrast to NSs, nonnative speakers (NNSs) processed congruent collocations significantly faster than English-only collocations. As for frequency, all three groups demonstrated sensitivity to both word-level and collocation-level frequency. However, the distributions differed across the three groups. We concluded that age/order of acquisition effects (Carroll & White, 1973) provided the best explanation for the congruency results. Regarding the frequency results, we concluded that the findings conflict with claims that NNSs may process formulaic sequences differently than NSs (e.g., Wray, 2002, 2008).
