Developmental links of very early phonological and language skills to second grade reading outcomes: strong to accuracy but only minor to fluency     

Puolakanaho A  Ahonen T  Aro M  Eklund K  Leppänen PH  Poikkeus AM  Tolvanen A  Torppa M  Lyytinen H 《Journal of learning disabilities》2008,41(4):353-370

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献   

Rats remember not wisely but too well     

Sarah Adams-pepper  Sylvain Gagnon  Susan Fore  H. L. Roitblat 《Learning & behavior》1992,20(4):363-372

Rats were trained in a three-alternative spatial delayed matching-to-sample task in a starburst maze. Samples consisted of rewarded forced choices of one arm, and retention was indicated by rats’ returning to that arm after a 90-sec delay. If a rat made an error on its first choice, it was returned to the start compartment and allowed a second choice. Unlike in previous experiments with this task, all three arms were available during the animals’ second choices. The rats tended to perseverate in their second choices by returning to the arm that they had erroneously visited on their first choice. In Experiment 1, the accuracy of second choices following first-choice errors was below chance during the first block of sessions, when a 90-sec delay intervened between the first choice and the second choice, and at chance during the second block of sessions, when a short (5–6 see) delay intervened between first and second choices. In Experiment 2, long-delay and short-delay sessions were randomly presented to naive subjects. Similar results were obtained. In both experiments, the tendency to repeat the erroneous first choice was greater when long delays separated the two choices than when short delays were used. The results suggest that rats make their first-choice errors because they erroneously encode or remember the location of the sample and that they base their second choices on the same erroneous-memory. The increase in perseveration at long delays implies some kind of rehearsal-like mechanism that slows forgetting of the memory controlling the first choice.  相似文献   

The role of educators of the deaf in the early identification of hearing loss   总被引：1，自引：0，他引：1  

Arehart KH  Yoshinaga-Itano C 《American annals of the deaf》1999,144(1):19-23

About 16,000 babies each year will be identified with hearing loss by age 3 months once universal newborn hearing screening becomes a reality. Identification of hearing loss in infancy, followed by appropriate intervention by age 6 months, can result in normal language development, regardless of degree of hearing loss. As the average age of identification of hearing loss moves downward toward 2 months, children with hearing loss will enter the educational system earlier and with language skills commensurate with those of their hearing peers. In order to provide appropriate services to children with hearing loss and their families, early interventionists will need to forge links to health care providers involved in universal newborn hearing screening programs, to have specialized training in deafness and hearing loss, and to have expertise in providing services to very young children and to children with hearing loss in the broad range from mild to profound.  相似文献

Children’s emotional and behavioral responses to peer provocation and early school adjustment     

Maria S. Poulou  Hideko H. Bassett 《Pastoral Care in Education》2018,36(3):205-222

ABSTRACT

Even very young children think about their own and others’ behavior, including emotions. Such cognitions and emotions about the self and others convey information that is crucial to social interactions and relationships. The current study based on an integrated model of emotion processes and cognition in social information processing (SIP) aimed to explore students’ emotional and behavioral responses in SIP choices, and their association with teacher-reported early school adjustment. Two-hundred and thirty pre-school and first-grade primary school students were interviewed using the Challenging Situations Task (CST). CST assessed students’ emotional and behavioral responses to 12 unambiguous hypothetical peer provocation situations. Children’s preschool and first-grade primary teachers rated children’s early school adjustment with the Social Competence and Behavior Evaluation (SCBE-30) measure. The results revealed that children chose mainly sad and angry emotions and socially competent and passive behaviors. We found a relationship both between sad emotions and socially competent behavior choices, and between angry emotion and aggressive behavior choices. Sad emotions and aggressive behavior choices were the main predictors of school adjustment. Children’s responses to peer provocation situations varied depending on how the children interpreted the situations. The results address the importance of children’s SIP and school adjustment.  相似文献   

Effects of maze geometry and experience on exploratory behavior in the rat     

H. J. Uster  K. Bättig  H. H. Nägeli 《Learning & behavior》1976,4(1):84-88

Rats were exposed twice in a rotated sequence to a series of six mazes, consisting of hexagonal alleys, balanced for different alley length and structural complexity. Locomotor activity increased with alley length and decreased with structural complexity of the mazes. Locomotion became less stereotyped with increased experience, showing an increasing number of turns, less constant velocity, loss of the initial preference for outward leading alleys and weakening of the forward tendency at reentry from side alleys into hexagonal alleys. In contrast to these qualitative changes of locomotion, the amount of activity remained almost unchanged throughout the experiment. The results suggest that these increases in locomotion complexity depend upon complex interactions between experience and stimulus content of the mazes.  相似文献

The paper describes the design and use of a studio system which arose out of the need to give demonstrations of experimental procedures to practical classes of up to 150 students. Since the requirements could be specified in some detail it was possible to use novel methods of working which turned out to be very efficient and economical.  相似文献
