Spatial Working Memory: How You Hold Locations in Mind

While following a recipe, you might need to remember that the flour is in the cupboard to your left while you're working at the counter to your right — holding that location active in mind for the few seconds it takes to need it again. This is spatial working memory in action: the capacity to keep spatial positions and locations available for immediate use, over a timescale of seconds rather than the days or years of long-term spatial memory.

Spatial working memory is distinct from — though closely related to — both long-term spatial memory and visuospatial working memory more broadly. This article focuses specifically on the capacity to hold locations and positions active in mind: how much you can hold, which brain regions make it possible, and how it can be measured and trained.

We have embedded a free Spatial Span Test at the bottom of this page — the standard way to measure this exact capacity.

The Network That Holds Locations in Mind

Holding a spatial location active in mind depends on a distributed network of brain regions, with the dorsolateral prefrontal cortex (dlPFC) playing a central role. Research on patients with dlPFC brain lesions found that damage to this region produces clear deficits in the manipulation of spatial knowledge in working memory — distinguishing it from simple storage. The right dlPFC in particular was found to be critical for manipulating information across a broad range of spatial reasoning tasks, while the left dlPFC was specifically necessary for actively manipulating information held in working memory.

The dlPFC does not work alone. Research using transcranial magnetic stimulation — a technique that temporarily disrupts activity in a specific brain region — found that the dlPFC, frontal eye fields, superior parietal lobule, and intraparietal sulcus all contribute to the short-term retention of spatial information. Disrupting any of these regions impaired performance on spatial working memory tasks, confirming that holding a location in mind depends on coordinated activity across frontal and parietal cortex rather than a single dedicated region.

This frontoparietal network is thought to maintain spatial information through persistent neural activity — neurons that continue firing in a pattern that represents the held location throughout the delay period between encoding the position and using it. This is different from how long-term memories are stored, which rely more on structural and synaptic changes rather than ongoing activity.

How Much Can You Hold?

Spatial working memory has a limited capacity, typically estimated at four to seven locations for healthy adults — though this varies based on how the capacity is measured and the complexity of the spatial material. This is measured most directly using sequential tasks like the Corsi block-tapping test, where a sequence of locations must be observed and then reproduced in the same order.

Capacity develops through childhood and tends to decline somewhat with normal aging, following a broadly similar developmental trajectory to other working memory systems. Research tracking the development of spatial working memory in children and adolescents has found that capacity increases steadily through childhood, with continued refinement of the underlying neural systems into adolescence — a slower developmental trajectory than some other cognitive abilities, reflecting the protracted maturation of the prefrontal cortex.

Spatial working memory capacity is not identical to verbal working memory capacity in the same person — the two systems, though coordinated, can be selectively stronger or weaker depending on individual differences in the underlying neural systems that support each.

Holding vs Manipulating: Two Different Demands

An important distinction in spatial working memory research is between simply holding a location in mind and actively manipulating spatial information while holding it. Reproducing a sequence of locations in the order they were shown — the forward Corsi span — primarily tests holding capacity. Reproducing the sequence in reverse order — the backward Corsi span — additionally requires manipulation: reorganising the held information before using it.

This distinction matters because holding and manipulation appear to depend on at least partially separable neural mechanisms, with manipulation placing greater demands on prefrontal cortex specifically. People can show intact holding capacity with impaired manipulation, or vice versa, which is clinically useful for distinguishing different types of cognitive difficulty.

Why Spatial Working Memory Matters

Spatial working memory underlies a wide range of everyday tasks that involve tracking positions temporarily. Following multi-step directions requires holding the sequence of turns in mind until each is executed. Mental arithmetic involving spatial representation — like tracking carried digits in multi-digit calculations — draws on this capacity. Games and sports that require tracking multiple moving positions simultaneously place heavy demands on spatial working memory.

It also plays a supporting role in mental rotation — holding the mental representation of a shape stable while it is being rotated requires spatial working memory capacity, and people with stronger spatial working memory tend to perform better on mental rotation tasks, particularly at larger rotation angles where the demand on holding capacity is greater.

Individual Differences and What Affects Them

Spatial working memory capacity varies considerably between people, and this variation predicts performance across a range of spatially demanding tasks. Several factors contribute to this variation: baseline neural differences in the frontoparietal network, experience with spatially demanding tasks and professions, attentional control (since spatial working memory depends partly on the ability to maintain focus on the held information without interference), and age, with capacity generally peaking in early adulthood.

Stress and fatigue also reduce spatial working memory performance, consistent with its dependence on active, effortful neural maintenance rather than passive storage. This is one reason performance on spatial working memory tasks can vary meaningfully for the same person across different testing conditions.

Training Spatial Working Memory

Spatial working memory responds to targeted practice. Training studies using sequential spatial tasks similar to the Corsi block-tapping format consistently show improvements in span and accuracy, with the gains reflecting genuine capacity improvement when training uses varied, progressively challenging material rather than repeated exposure to the same patterns.

The Spatial Span Test below directly trains this capacity using the validated Corsi format. Related tools on the Spatial Reasoning hub — including mental rotation and maze navigation — draw on spatial working memory as a supporting skill, meaning improvements here can have benefits across multiple spatial reasoning domains.

Test Your Spatial Working Memory

The test below directly measures your spatial working memory capacity using the Corsi block-tapping format. Watch the blocks light up in sequence, then reproduce the pattern in the same order — your score reflects how many locations you can reliably hold active in mind.
