A word-spotting task is used in Spanish to test the way in which polysyllabic letter-strings are parsed in this language. Monosyllabic words (e.g., "bar") embedded at the beginning of a pseudoword were immediately followed by either a coda-forming consonant (e.g., "barto") or a vowel (e.g., "baros"). In the former…

Joint attention has been extensively studied in the developmental literature because of overwhelming evidence that the ability to socially coordinate visual attention to an object is essential to healthy developmental outcomes, including language learning. The goal of this study was to understand the complex system of sensory-motor behaviors that…

It is surprising that there are inconsistent findings of transitive inference (TI) in young infants given that non-linguistic species succeed on TI tests. To conclusively test for TI in infants, we developed a task within the social domain, with which infants are known to show sophistication. We familiarized 10- to 13-month-olds (M = 11.53 months)…

Children with Specific Language Impairment (SLI) have language difficulties of unknown origin. Syntactic profiles are atypical, with poor performance on non-canonical structures, e.g. object relatives, suggesting a localized deficit. However, existing analyses using ANOVAs are problematic because they do not systematically address unequal…

Since task-based learning was proposed in the field of second language acquisition in the 1980s, the popularity of this teaching approach has risen due to the effectiveness in enhancing learners' communicative competence. To complete tasks, learners have opportunities to use the target language in various situations so that they can transfer what…

We investigate the challenges students face in the transition from calculus courses, focusing on methods related to the analysis of real valued functions given in closed form, to more advanced courses on analysis where focus is on theoretical structure, including proof. We do so based on task design aiming for a number of generic potentials for…

Although engineering education has been practiced at the undergraduate level for over a century, only fairly recently has the field broadened to include the elementary level; the pre-college division of the American Society of Engineering Education was established in 2003. As a result, while recent education standards require engineering in…

Two leading theories regarding the neurocognitive basis of attentional disorders are the executive dysfunction theory and the state regulation theory. The executive dysfunction theory takes a top-down approach, explaining the symptoms of ADHD as a byproduct of general deficits in executive functioning--particularly disinhibition. The state…

The authors who are mathematics teacher educators, have found that classifying, composing, and transforming shapes (in particular, rotations and reflections) are areas of difficulty for adults as well as for children. However, these are also some of the most important geometric ideas. They are fundamental topics in the K-8 Geometry and Measurement…

Orthographic forms (spellings) can affect pronunciation in a second language (L2); however, it is not known whether the same orthographic form can affect both L2 pronunciation and metalinguistic awareness. To test this, we asked 260 speakers of English--first-language (L1) English speakers, L1 Italian and L2 English sequential bilinguals, and L1…

Verbal working memory resources may impact syntax comprehension. Thirteen Italian children with cochlear implants (CIs) were assessed in relative clause (RC) comprehension, digit span and nonword repetition and compared to 13 chronological age peers (CA) and 13 younger controls (LA) with normal hearing (NH). The RC comprehension task tested…

Collaborative dialogue has been seen as an important aspect of L2 learning. However, the extent to which collaborative dialogue contributes to learning depends very much on the context in which it takes place. Informed by a sociocultural perspective of learning, this study investigated the nature of the collaborative dialogue between complete…

Following the call in Sandlund, Sundqvist, and Nyroos (2016) for incorporating discursive approaches into the field of oral second language (L2) testing, this paper proposes an interactional usage-based approach to the analysis of oral L2 performance. Based on Eskildsen (2018a), we combine analytic tools from usage-based linguistics and…

The morphological structure of the word has a central function in the organization of the mental lexicon and word recognition. Polymorphemic words in Arabic are composed of two non-concatenated morphemes: root and word-pattern. This study is the first to address the issue of nominal-pattern priming among young developing Arabic speakers. I…

Given that words from the academic layer of English typically carry bound roots ("min" in "diminish") rather than free-standing base words ("small" in "smaller"), there is a need to understand the factors that make bound roots more or less accessible for morphological problem-solving unfamiliar words. We…
