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...

Life-span Changes in Visuo-spatial Short Term Memory

Several experiments are presented to evaluate the development of visuo-spatial short term memory from childhood to old age (from five-year-olds to about 70-year-olds). Visuospatial short term memory was assessed through transformational imagery tasks. The first set of experiments (chapters 3, 4 and 5) concerned the development of mental rotation abilities. A review of the literature suggested t...
