On Colour, Category Effects, and Alzheimer’s Disease: A Critical Review of Studies and Further Longitudinal Evidence

Table 5

Individual mean naming performance (percentage of correct responses) of AD patients according to domain (LT/NLT), format (colour/greyscale), and moment of evaluation (time-point-1/2).

Note. AD = Alzheimer’s disease, LT = living things, NLT = nonliving things. LT-NLT = difference between LT and NLT (negative values indicate better naming of NLT), f = female, m = male, and ne = not evaluated.
