The Relationship Between Our Ability in Travelling in Time and in Estimating Time Duration and Their Interaction With Spatial Attention: a Neuropsychological Study.
In Brief
An observational study evaluating Rightward Attentional Shift (R-PA) and Leftward Attentional Shift (L-PA) for Brain Disease. Completed, enrolled 74 participants across 1 site.
Detailed Summary
Time is an important function that permeates our everyday activities but it has been so far significantly under-investigated in neurological patients. For instance, it is known that right brain damaged (RBD) patients with spatial attentional deficit (neglect) are impaired in both the ability to estimate the duration of an event (Time Estimation), showing a time underestimation, and the ability of mentally moving in past and future time (Mental Time Travelling), showing a deficit in processing future events when they are projected in the past. After a leftward shift of spatial attention induced by prismatic adaptation (PA), both the underestimation and the ability to travel in time ameliorate. However, less is known about these abilities in left brain damaged (LBD) patients. Aims of this study are to investigate: i) the performance (in terms of accuracy and reaction times) of LBD and RBD patients on Mental Time Travelling; ii) the correlation between Mental Time Travelling and Time Estimation abilities; iii) the efficacy of a single session of PA inducing a leftward (L-PA) and a rightward (R-PA) attentional shift on Mental Time Travelling and Time Estimation abilities. A group of control subjects will be involved for comparison among groups.

Interventions
Patients will perform a session of 90 pointing movements toward a visual target presented on the right, the left or at the center of the visual field. This pointing task will be performed with prismatic googles inducing a rightward attentional shift.
