Table 2.

Individual patients’ z-scores and t-values calculated with the Crawford & Garthwaite method (Crawford & Garthwaite, 2002) compared to age-matched control samples in each paradigm. The threshold for significance was a t-value of 1.771 given the control sample size of 14 in each paradigm. All significant t-values are in bold. Only two out of six patients had a larger interference effect than age-matched controls in the continuous paradigm whereas five out of six patients had a larger interference effect than age-matched controls in the blocked-cyclic picture naming paradigm.
