Visuo-spatial Working Memory

Complexity effects in visuo-spatial working memory: implications for the role of long-term memory.

Several studies have shown that the capacity of visuo-spatial working memory is limited by complexity. Using a variant of the Corsi blocks task, this paper investigates the effect of complexity of the to-be-remembered path on visuo-spatial memory span. Redundancy was determined by three Gestalt principles: symmetry, repetition, and continuation. Experiment 1 revealed an effect of path complexit...

The time course of visuo-spatial working memory updating revealed by a retro-cuing paradigm

We investigated the influence of non-cued working memory representations on further information processing. A retro-cue indicated if items on the left or right side of a previous memory array remained relevant. Subsequently, a central probe item was presented with a varying stimulus onset asynchrony (SOA: 300, 400, 600, 1,000, 1,800 ms). Participants had to state whether this stimulus was shown...

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...

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 ...
