  1. p < 0.05; MNSQ mean square
  2. aMeasured in logit; positive item logit indicates that the item requires a lower visual ability, than the mean of the items and is an easier item, whereas a negative item logit indicates that, the item requires a higher visual ability than the mean of the items and is a more difficult item
