Neuroscience research links alexithymia, the difficulty in identifying and describing feelings and emotions, with left hemisphere dominance and/or right hemisphere deficit. To provide behavioral evidence for this neuroscientific hypothesis, we explored the relationship between alexithymia and performance in a line bisection task, a standard method for evaluating visuospatial processing in relation to right hemisphere functioning. We enrolled 222 healthy participants who completed a version of the 20-item Toronto Alexithymia Scale (TAS-20), which measures alexithymia, and were asked to mark (bisect) the center of a 10-cm horizontal segment. The results document a significant rightward shift in the center of the line in participants with borderline and manifest alexithymia compared with non-alexithymic individuals. The higher the TAS-20 score, the greater the rightward shift in the line bisection task. This finding supports the right hemisphere deficit hypothesis in alexithymia and suggests that visuospatial abnormalities may be an important component of this mental condition.

AbstractWe 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.
