Phonological Awareness and Beginning Reading in Spanish-Speaking ESL First Graders: Research into Practice

In the first study, 30 Spanish-speaking English-as-a-second language (ESL) first graders whose families were Latino immigrants and who received all their school instruction in English completed an assessment battery with both Spanish and English measures of phonological awareness, Verbal IQ (VIQ), oral language proficiency, and single-word reading (real words and pseudowords); they also named English alphabet letters. Phonological awareness in Spanish predicted (a) phonological awareness in English and (b) English word reading; thus, phonological awareness may transfer across first and second languages and across oral and written language. English VIQ and oral language proficiency predicted both English and Spanish word reading, but Spanish VIQ and oral language proficiency did not predict English word reading. In the second study, the 4 males and the 4 females with the lowest reading achievement participated in an instructional design experiment in which empirically supported instructional components for teaching beginning reading to monlingual English speakers were included. These components were phonological awareness training (in both Spanish and English), explicit instruction in alphabetic principle (in English), and repeated reading of engaging English text with comprehension monitoring (in English). Both individual students and the group as a whole increased in real-word reading and pseudoword reading beyond the level expected on the basis of their Spanish or English VIQ or oral proficiency. Implications of this research for school psychology practice are discussed, especially the importance of early reading intervention and progress monitoring for Spanish-speaking ESL first graders.     

Early language and the development of children's reading skills

There is considerable agreement that vocabulary plays a central role in reading acquisition, but there is less agreement about whether this association is direct or indirect through phonological and print-related knowledge. Longitudinal data from 77 African-American children were analyzed to examine the relationship between language skills, phonological knowledge and print processing skills at pre-kindergarten and kindergarten with reading at pre-kindergarten through second grade. Analyses indicated that home and child care experiences were related to reading indirectly through language and that language and phonological knowledge were both directly related to acquisition of reading skill. This study of African-American children and previous studies of lower- and middle-income children indicate both language and phonological skills play an important role in children becoming successful readers, and that experiences at home and in child care during in early childhood play a role in the acquisition of reading through their enhancement of early language and phonological skills.     

Relationships among motor skill,perceived self-competence,fitness, and physical activity in young adults

PurposeThis large-scale, exploratory study sought to examine the associations between motor skill proficiency (MSP), perceived self-competence (PC), physical fitness (PF), and self-reported physical activity (PA) to assess the assumption that relationships among these variables found in childhood and adolescence persist into young-adulthood. Specifically, predictors of PF and PA were assessed. Additionally, the contributions body mass index (BMI) and gender made to these relationships, as well as that of process- versus product-oriented motor skills data, were studied. Finally, how these relationships differed by gender was explored.MethodsParticipants’ (n = 448) MSP was assessed using select measures from the TGMD-2 and the BOT-2, while PF was evaluated using the FitnessGram. Participants also completed surveys to assess PC (SPPCS), PA (past-week MAQ), and demographic information. Height and weight were collected to calculate BMI.ResultsModels predicting physical fitness had good fit to the observed data, with perceived athletic competence, locomotor skill, upper-limb coordination, BMI, and gender accounting for about 75% (R² = 0.748) of aerobic PF variance and about 48% (R² = 0.476) of variance in push-up performances. About 18% (R² = 0.178) of variance in curl-up performances was predicted by perceived athletic competence, locomotor skill, upper-limb coordination, and PA. The PA model demonstrated weaker predictive power, with only about 10% (R² = 0.097) of variance explained. When considering male and female models separately, female models demonstrated better fit when predicting all PF and PA outcome variables. BMI and gender operated as significant predictors to differing degrees across the various models.ConclusionsThere is compelling evidence to believe relationships found among MSP, PC, PF, and PA in childhood and adolescence also exist in early adulthood. However, differences in the roles of gender and physical fitness versus physical activity are likely to exist.     

认知加工的自动化现象：从二分法到渐进观

认知自动化是人类学习和进步的必经之路。传统的二分法通过无意识等特征简单地将认知加工过程分为受控加工与自动化加工。但这些特征取决于研究者所采用的研究范式, 不具有普适性。近年来研究者根据注意资源有限理论提出自动化是一个渐进的过程, 而注意资源需求的减少是自动化发展的核心特征。相比二分法, 这种渐进观更加符合实证研究的发现。而且, 渐进观在信息加工自动化理论和技能习得理论的阶段性中都得以体现, 进一步证明了渐进观的普适性。     

Impaired sequential and partially compensated probabilistic skill learning in Parkinson's disease

The striatal dopaminergic dysfunction in Parkinson's disease (PD) has been associated with deficits in skill learning in numerous studies, but some of the findings remain controversial. Our aim was to explore the generality of the learning deficit using two widely reported skill learning tasks in the same group of Parkinson's patients. Thirty-four patients with PD (mean age: 62.83 years, SD: 7.67) were compared to age-matched healthy adults. Two tasks were employed: the Serial Reaction Time Task (SRT), testing the learning of motor sequences, and the Weather Prediction (WP) task, testing non-sequential probabilistic category learning. On the SRT task, patients with PD showed no significant evidence for sequence learning. These results support and also extend previous findings, suggesting that motor skill learning is vulnerable in PD. On the WP task, the PD group showed the same amount of learning as controls, but they exploited qualitatively different strategies in predicting the target categories. While controls typically combined probabilities from multiple predicting cues, patients with PD instead focused on individual cues. We also found moderate to high correlations between the different measures of skill learning. These findings support our hypothesis that skill learning is generally impaired in PD, and can in some cases be compensated by relying on alternative learning strategies.     

Phonological recoding and rapid orthographic learning in third-graders' silent reading: a critical test of the self-teaching hypothesis

This study examined rapid orthographic learning following silent reading in third-grade children as a function of number of target nonword repetitions and test delay. In each of two test sessions at least 6 days apart, children read a series of short stories, with each story containing a different nonword repeated either four or eight times. In the second session, after the stories had been read, children were asked to read short lists of target nonwords or homophonic alternatives. Children read target nonwords faster than homophones, indicating that they had formed functional orthographic representations of the target nonwords through phonologically recoding them during silent story reading. They also preferred target nonwords to homophones in an orthographic choice task in which the alternatives included the target, the homophone, and a visually similar foil, although here orthographic learning was stronger for items encountered eight times within stories and stronger for items tested immediately. These findings provide critical evidence in support of Share's self-teaching through phonological recoding hypothesis.     

Quality of phonological representations, verbal learning, and phoneme awareness in dyslexic and normal readers

This study of dyslexia was concerned with the quality of phonological representations of lexical items. It extended the studies of verbal learning in dyslexia from learning new vocabulary items (pseudo-names) to the learning of more well-specified variants of known words. The participants were 19 dyslexic adolescents in grades 4 to 6 and 19 younger normal readers in grade 2 matched on single word decoding. The dyslexics were significantly outperformed by the reading-age controls in non-word reading and in phoneme awareness. The dyslexics also took longer time to learn to associate a set of pseudo-names with pictures of persons although the dyslexics learned to associate familiar names with pictures as quickly as the controls did. The acquisition of new phonological representations of words was studied in an imitation task with maximally distinct pronunciations of long, familiar words. The dyslexics gained less than the controls in this task. They also gained less on one measure taken from a phoneme substitution task with the same words as in the distinctness task. The results are interpreted in the light of the hypothesis that poorly specified phonological representations may be an underlying problem in dyslexia.     

Modulation of brain activity during phonological familiarization

We measured brain activity in 12 adults for the repetition of auditorily presented words and nonwords, before and after repeated exposure to their phonological form. The nonword phoneme combinations were either of high (HF) or low (LF) phonotactic frequency. After familiarization, we observed, for both word and nonword conditions, decreased activation in the left posterior superior temporal gyrus, in the bilateral temporal pole and middle temporal gyri. At the same time, interaction analysis showed that the magnitude of decrease of activity in bilateral posterior temporal lobe was significantly smaller for LF nonwords, relative to words and HF nonwords. Decrease of activity in this area also correlated with the size of behavioral familiarization effects for LF nonwords. The results show that the posterior superior temporal gyrus plays a fundamental role during phonological learning. Its relationship to sublexical and lexical phonological processing as well as to phonological short-term memory is discussed.     

Symbol-string sensitivity and adult performance in lexical decision

In this study of adult readers, we used a symbol-string task to assess participants' sensitivity to the position of briefly presented, non-alphabetic but letter-like symbols. We found that sensitivity in this task explained a significant proportion of sample variance in visual lexical decision. Based on a number of controls, we show that this relationship cannot be explained by other factors including: chronological age, intelligence, speed of processing and/or concentration, short term memory consolidation, or fixation stability. This approach represents a new way to elucidate how, and to what extent, individual variation in pre-orthographic visual and cognitive processes impinge on reading skills, and the results suggest that limitations set by visuo-spatial processes constrain visual word recognition.
