background and purpose: study skills is one important factor influencing academic achievement of students . we must replace ineffective models and habits of study with more fruitful skills in order to gain better learning. this study investigates the study skills and habits of medical students and their educational achievement. methods: based on a pilot study the sample size was estimates as 40...

While it is well known that reading is highly heritable, less has been understood about the bases of these genetic influences. In this paper, we review the research that we have been conducting in recent years to examine genetic and environmental influences on the particular reading processes specified in the dual-route cognitive model of reading. We argue that a detailed understanding of the r...

We examined the Simple View of reading from a behavioral genetic perspective. Two aspects of word decoding (phonological decoding and word recognition), two aspects of oral language skill (listening comprehension and vocabulary), and reading comprehension were assessed in a twin sample at age 9. Using latent factor models, we found that overlap among phonological decoding, word recognition, lis...

In some mammalian genes, the paternally and maternally derived alleles are expressed differently: this phenomenon is called genomic imprinting. Here we study the evolution of imprinting using multivariate quantitative genetic models to examine the feasibility of the genetic conflict hypothesis. This hypothesis explains the observed imprinting patterns as an evolutionary outcome of the conflict ...

Most vocabulary learning should occur incidentally through listening and reading. This is one of the  reasons  why  a  substantial  extensive  reading  program  is  an  important  part  of  an  English course.  Extensive  reading  requires  the  learners  to  do  large quantities  of  reading  using  material that  is  at  the  right  level  for  them.  Vocabulary  learning  occurs  through  th...

Models of reading have typically focused on monosyllabic words, consequently lexical stress assignment has been neglected in such models. Yet, determining how and when stress is applied in naming is an important consideration in providing a comprehensive account of reading processing. A corpus analysis of English age-appropriate reading materials between ages 5-12 indicated two properties: a ge...

In English, gains in decoding skill do not map directly onto increases in word reading. However, beyond the Self-Teaching Hypothesis (Share, 1995), little is known about the transfer of decoding skills to word reading. In this study, we offer a new approach to testing specific decoding elements on transfer to word reading. To illustrate, we modeled word-reading gains among children with reading...
