Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For instance, it is known that right brain damaged (RBD) patients with spatial attentional deficit (neglect) underestimate durations of milliseconds and show a deficit in processing future events when they are projected in the past.
Moreover, previous studies have demonstrated that a leftward shift of spatial attention induced by prismatic adaptation (PA) determines an amelioration of both, time underestimation and the deficit in mental travel in time.
The Mental Time Travelling, in particular, seems to involve different cognitive functions, among others, episodic memory and the ability to anticipate the future. Recent evidence suggests that these functions are mediated by neural circuits localized in the left hemisphere but no studies have investigated the ability of mentally moving in past and future time 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.

Study Groups

LBD patients R-PA
A group of 10 left brain damaged (LBD) patients will attend two sessions:
1. First session - before prismatic adaptation (pre-PA): they will perform a computerized test battery to measure time abilities (Mental Time Travel and Time Estimation) and a neuropsychological test battery to assess cognitive abilities.
2. Second session - after prismatic adaptation (post-PA): they will perform the Mental Time Travel and Time Estimation tasks immediately after a single session of pointing with prismatic goggles inducing rightward attentional shift (R-PA).
Rightward Attentional Shift (R-PA)
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.
