According to Crain and Nakayama (1987), when forming complex yes/no questions, children do not make errors such as "Is the boy who smoking is crazy?" because they have innate knowledge of "structure dependence" and so will not move the auxiliary from the relative clause. However, simple recurrent networks are also able to avoid…

In this policy brief, the author explores the problems with attainment measures when it comes to evaluating performance at the school level, and explores the best uses of value-added measures. These value-added measures, the author writes, are useful for sorting out-of-school influences from school influences or from teacher performance, giving…

The aim of this study was to find the most prominent source of intersubject variability in neuronal activation for reading familiar words aloud. To this end, we collected functional imaging data from a large sample of subjects (n = 76) with different demographic characteristics such as handedness, sex, and age, while reading. The…

Cognitive, word-level reading, spelling and writing measures were administered to academically at-risk undergraduates with writing difficulties to examine their literacy profiles; and performance was compared to typically-achieving writers. The at-risk students were slower and less accurate on measures of sight word reading, lexical decision,…

Children in third and fourth grades suffering from developmental dyscalculia (DD) and typically developing children were asked to compare numbers to a standard. In two separate blocks, they were asked to compare a number between 1 and 9 to 5, or a two-digit number between 10 and 99 to 55. In the single-digit comparisons, DD children were…

Autism spectrum disorders (ASD) have been gaining attention, partly as an example of unusual developmental trajectories related to early neurobiological differences. The present investigation addressed the process of learning new words to explore mechanisms of language delay and impairment. The sample included 21 typically developing toddlers…

Dutch-English participants named words and nonwords with a between-language phonologically inconsistent rime, e.g., GREED and PREED, and control words with a language-typical rime, e.g., GROAN, in a monolingual stimulus list or in a mixed list containing Dutch words. Inconsistent items had longer latencies and more errors than typical items in the…

Recent federal education policies and reports have generated considerable debate about the meaning, methods, and goals of "scientific research" in mathematics education. Concentrating on the critical problem of determining which educational programs and practices reliably improve students' mathematics achievement, these policies and reports focus…

The aim of the present study is to provide further evidence that the errors that arise from improper application of the linear model are not random and not easy to overcome. Using three different types of test, we attempt to show that the errors referred to in the literature as "pseudo-analogous" are the result of an epistemological…

Special ability in computing the day of the week from given dates was observed in a 18 years old male, L.E., suffering from autism. Neuropsychological testing revealed severe deficits in all cognitive domains and poor explicit knowledge of calendar structure. The subject scored well above the chance level on dates of the past and future decades.…

A total of 51 Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) protocols, administered by graduate students in training, were examined to obtain data describing the frequency of examiner errors and the impact of errors on resultant test scores. Present results were generally consistent with previous research examining graduate…

Vieta's famous product using factors that are nested radicals is the oldest infinite product as well as the first non-iterative method for finding [pi]. In this paper a simple geometric construction intimately related to this product is described. The construction provides the same approximations to [pi] as are given by partial products from…

Three-year-olds were given a search task with conflicting cues about the target's location. A ball rolled behind a transparent screen and stopped behind one of four opaque doors mounted into the screen. A wall that protruded above one door provided a visible cue of blockage in the ball's path, while the transparent screen allowed visual tracking…

The authors investigated whether a series of mini prewriting assignments linked to a formal paper describing an original research project would improve preservice elementary teachers' writing abilities in a science context. They compared 38 final reports from students who completed the prewriting assignments with 38 reports randomly selected from…

This study examines how conversing with passengers in a vehicle differs from conversing on a cell phone while driving. We compared how well drivers were able to deal with the demands of driving when conversing on a cell phone, conversing with a passenger, and when driving without any distraction. In the conversation conditions, participants were…
