Children diagnosed with cerebral palsy (CP) often show difficulties in arithmetic compared to their typically developing peers. The present study explores whether cognitive and motor variables are related to arithmetic performance of a large group of primary school children with CP. More specifically, the relative influence of non-verbal…

A person-oriented approach examined patterns of functioning in social and executive function domains at 54 months and in turn forecasted 5th-grade socioemotional and achievement outcomes for 944 children. Six distinct profiles of 54-month school readiness patterns predicted outcomes in 5th grade with indications of cross-domain association between…

In spring of 2010, three high school teachers and their students paired with a college teacher and her advanced writing class to collaborate on oral history research and writing. While many people think of oral history as "just stories," the authors introduce it to students as a rigorous method for documenting historical events, cultural…

Purpose: To compare the development of phonological skills in children with specific language impairment (SLI) with and without literacy delay and to examine whether kindergarten phonological skills could discriminate these 2 groups. Method: In a longitudinal study, 8 children with SLI and literacy delay, 10 children with SLI and normal literacy,…

Undergraduate students were asked to complete gas law questions using a Web-based tool as a first step in our understanding of the role of cognitive load in chemistry word questions and in helping us assess student problem-solving. Each question contained five different complexity factors, which were randomly assigned by the tool so that a…

Healthy aging is characterized by a number of changes on brain structure and function. Several neuroimaging studies have shown an age-related reduction in hemispheric asymmetry on various cognitive tasks, a phenomenon captured by Cabeza (2002) in the Hemispheric Asymmetry Reduction in Older Adults (HAROLD) model. Although this phenomenon is…

A printed module should consist of media elements, namely text and pictures, which are self-instructional and could cater to the needs of the user. However, the typical platform of such visualization frequently overloads the limited working memory causing split attention and redundancy effects. The purpose of this study is to design and develop a…

It is well documented that many successful individuals are challenged by cognitive-based disabilities that impact their performance in school and on tests. While commonly believed to be related mostly to the constructs of processing speed or reading fluency, there are other aspects of cognition that affect how an individual interacts with the…

The consistency of flashbulb memories over long delays provides a test of theories of memory for highly emotional events. This study used September 11, 2001 as the target event, with test-retest delays of 2 and 3 years. The nature and consistency of flashbulb memories were examined as a function of delay between the target event and an initial…

Presents a postscript to the current authors' response to the comments by J. S. Bowers, M. F. Damian, and C. J. Davis on the current authors' original article, "Short-term memory for serial order: A recurrent neural network model,". Here, Botvinick and Plaut address Bowers et al's assertions that neurophysiological studies that have reported…

The human visual system can notice differences between memories of previous visual inputs and perceptions of new visual inputs, but the comparison process that detects these differences has not been well characterized. In this study, the authors tested the hypothesis that differences between the memory of a stimulus array and the perception of a…

Among the most fundamental issues in cognitive neuroscience is how the brain may be organized into process-specific and stimulus-specific regions. In the episodic memory domain, most functional neuroimaging studies have focused on the former dimension, typically investigating the neural correlates of various memory processes. Thus, there is little…

We investigated whether search accuracy of adult humans could be enhanced using differential reward contingencies in landmark-based spatial tasks conducted on a computer screen. We found that search accuracy was significantly enhanced by differential outcomes in a conditional spatial search task, in which the landmark-to-goal relationship depended…

When Stanford University obtained the Buckminster Fuller archive, it heralded it as "one of the most extensive known personal archives in existence." Taking up 2000 linear feet of shelf space, including hundreds of thousands of pages and over 4000 hours of audio/video, Fuller's collection does indeed sound impressive. But Fuller, considered an…

Elucidating the functional properties of the dentate gyrus (DG), CA3, and CA1 areas is critical for understanding the role of the dorsal hippocampus in contextual fear memory processing. In order to specifically disrupt various hippocampal inputs, we used region-specific infusions of DCG-IV, the metabotropic glutamate receptor agonist, which…
