Spatial Working Memory Counts: Evidence for a Specific Association Between Visuo-spatial Working Memory and Arithmetic in Children

Visuo-spatial Working Memory

Visuo-spatial Working Memory and the Comprehension of Iconic Gestures

Multi-modal discourse comprehension requires speakers to combine information from speech and gestures. To date, little research has addressed the cognitive resources that underlie these processes. Here we used a dual task paradigm to test the relative importance of verbal and visuo-spatial working memory in speech-gesture comprehension. Healthy, collegeaged participants encoded either a series ...

Functional neuroanatomy of visuo-spatial working memory in Turner syndrome.

Turner syndrome (TS), a genetic disorder characterized by the absence of an X chromosome in females, has been associated with cognitive and visuo-spatial processing impairments. We utilized functional MRI (fMRI) to investigate the neural substrates that underlie observed deficits in executive functioning and visuo-spatial processing. Eleven females with TS and 14 typically developing females (a...

The Effect of Stress on Visuo-Spatial Working Memory

Stressful events are known to affect a range of cognitive functions, such as attention, memory formation and memory recall. With regard to visuo-spatial working memory, the relationship is particularly complex. In part, this complexity arises from an incomplete picture of visuo-spatial working memory that does not fit well with the experimental literature. The aim of the present study is to rec...

Genetic Association Study of Spatial Working Memory

GENETIC ASSOCIATION STUDY OF SPATIAL WORKING MEMORY Mingkuan Lin, Ph.D. George Mason University, 2009 Dissertation Director: Dr. Karl J. Fryxell Working memory (WM) is a collection of cognitive processes that include short term storage of task related information and manipulation of this information to facilitate the transformation of memory to action immediately. Age-related declines in WM per...
