Imagine Your Crossed Hands as Uncrossed: Visual Imagery Impacts the Crossed-Hands Deficit.

Successful interaction with our environment requires accurate tactile localization. Although we seem to localize tactile stimuli effortlessly, the processes underlying this ability are complex. This is evidenced by the crossed-hands deficit, in which tactile localization performance suffers when the hands are crossed.

Exploring Reference Frame Integration Using Response Demands in a Tactile Temporal-Order Judgement Task.

Exploring the world through touch requires the integration of internal (e.g., anatomical) and external (e.

Haptic awareness changes when lying down.

Accurate localization of touch requires the integration of two reference frames-an internal (e.g., anatomical) and an external (e.

Reliability of the Crossed-Hands Deficit in Tactile Temporal Order Judgements.

Crossing the hands over the midline impairs performance on a tactile temporal order judgement (TOJ) task, resulting in the crossed-hands deficit. This deficit results from a conflict between two reference frames - one internal (somatotopic) and the other external (spatial) - for coding stimulus location. The substantial individual differences observed in the crossed-hands deficit highlight the differential reliance on these reference frames.
