We used desk-based tasks to evaluate and clarify the effects of colour lightness differences (Liebmann effect) in patients with left unilateral spatial neglect (USN) following stroke. Participants were 30 adults with USN (16 men and 14 women; mean age = 72.3 years, SD = 8.9 years). They took the ‘Letter Cancellation Test’ of the Japanese version of the Behavioral Inattention Test using two types of paper: black letters with a yellow background (‘black on yellow’) and red letters with a green background (‘red on green’). They also took the Line Bisection Test and their laterality index (LI) was also determined. Paired t-tests were computed comparing the LI by colour displays. LI was higher for ‘black on yellow’ than for ‘red on green’ in patients with mild left USN. However, LI for ‘red on green’ was higher in patients with severe left USN. Colour lightness differences are likely on the left side in patients with relatively mild left USN, but not in those with severe left USN.
