Fractionation of visuo-spatial memory processes in bipolar depression: a cognitive scaffolding account

Fractionation of visuo-spatial memory processes in bipolar depression: a cognitive scaffolding account.

BACKGROUND Previous studies of neurocognitive performance in bipolar disorder (BD) have demonstrated impairments in visuo-spatial memory. The aim of the present study was to use an object-location memory (OLM) paradigm to assess specific, dissociable processes in visuo-spatial memory and examine their relationship with broader neurocognitive performance. METHOD Fifty participants (25 patients...

Development of memory for pattern and path: further evidence for the fractionation of visuo-spatial memory.

Evidence from a number of sources now suggests that the visuo-spatial sketchpad (VSSP) of working memory may be composed of two subsystems: one for maintaining visual information and the other for spatial information. In this paper we present three experiments that examine this fractionation using a developmental approach. In Experiment 1, 5-, 8-, and 10-year old children were presented with a ...

Visuo-spatial Working Memory

The Cognitive-Initiative Account of Depression-Related Impairments in Memory

Visuo-spatial working memory span: a sensitive measure of cognitive deficits in children with ADHD.

Working memory (WM) has been hypothesised to be impaired in attention-deficit/hyperactivity disorder (ADHD). However, there are few studies reported on tests measuring visuo-spatial WM (VSWM) in ADHD. Some of these studies used paradigms including episodic memory, others only used low memory loads. In the present study we used a VSWM test that has not been used previously in ADHD research. The ...
