These experiments examined the relationship between the neurotrophic factor fibroblast growth factor 2 (FGF2) and individual differences in the expression of conditioned fear. Experiments 1 and 2 demonstrated that rats naturally expressing low levels of contextual or cued fear have higher levels of hippocampal FGF2 relative to rats that express…

In this article, Riverdale Country School (New York) learning specialist, Brooke McCaffrey describes teaching methods, motivational techniques, and resources for parents of struggling readers.

The aim of the present study was to analyze the relative influence of age at implantation, parental expansions, and child language internal factors on grammatical progress in children with cochlear implants (CI). Data analyses used two longitudinal corpora of spontaneous speech samples, one with twenty-two and one with twenty-six children,…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, also known as "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar.…

This article introduces two sophisticated statistical modeling techniques that allow researchers to analyze systematicity, individual variation, and nonlinearity in second language (L2) development. Generalized linear mixed-effects models can be used to quantify individual variation and examine systematic effects simultaneously, and generalized…

Recent research has provided evidence that the information provided before a story--a spoiler--may increase the enjoyment of that story, perhaps by increasing the processing fluency experienced during reading. In one experiment, we tested the reliability of these findings by closely replicating existing methods and the generality of these findings…

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan,…

Purpose: The intersection of treatment intensity and communication intervention is an emerging area of investigation. Milieu teaching (MT) approaches for teaching communication skills to children with autism spectrum disorder (ASD) have a substantial evidence base (see Goldstein, 2002). However, a relatively small percentage (37.8%) of MT studies…

Learning of fractions is difficult for children in general and especially difficult for children with mathematics difficulties (MD). Recent research on developmental and individual differences in fraction knowledge of MD and typically achieving (TA) children has demonstrated that U.S. children with MD start middle school behind TA peers in…

The perspective-adjustment model of language interpretation assumes an initial egocentric stage in comprehension that is only later adjusted to the interlocutor's perspective. Moreover, substantial processing resources are involved in perspective-taking. However, many experiments in the perspective-adjustment framework do not control for visual…

Individuals with greater cognitive abilities generally show reduced rates of mind-wandering when completing relatively demanding tasks (Randall, Oswald, & Beier, 2014). However, it is yet unclear whether elevated rates of mind-wandering among low-ability individuals are manifestations of deliberate, intentional episodes of mind-wandering…

I was tangentially aware of gifted education while I was in elementary and middle school, but my first real awareness of the concept came through my work in the University Honors Program at Texas A&M. In truth, I was not yet working for the University Honors Program; I was a graduate assistant for then-Associate Director, Finnie Coleman, who…

The key to the success of any online program is dedicating attention to student satisfaction. Student satisfaction with what and how they learn in an online classroom is an important variable to understand and can help instructors and course designers create an environment that fits students' needs. This can be achieved with adequate course…

Digit comparison is strongly related to individual differences in children's arithmetic ability. Why this is the case, however, remains unclear to date. Therefore, we investigated the relative contribution of three possible cognitive mechanisms in first and second graders' digit comparison performance: digit identification, digit--number word…

This study investigated the processes reflected in the widely observed N400 and P600 event-related potential (ERP) effects and tested the hypothesis that the N400 and P600 effects are functionally linked in a tradeoff relationship, constrained in part by individual differences in cognitive ability. Sixty participants read sentences, and ERP…
