Neural Correlates of Changes in a Visual Search Task due to Cognitive Training in Seniors

Table 1

Demographic characteristics and cognitive status of the participant groups (Mini Mental State Examination, verbal IQ, forward and backward digit span, and Trail-Making Test A and B). Standard deviations are given in parentheses behind the mean values. There were no significant group differences as is indicated by the statistical analyses (last column).

Group	Cognitive training	No-contact control	Social control
Mean age	70.5 years (4.3)	69.7 years (4.5)	70.9 (4.4)	F(2, 102) = 1, P = .36
MMSE score	28.8 (1.9)	28.1 (1.9)	28.5 (1.6)	F(2, 102) = 1.4, P = .24
Verbal IQ (MWT-B)	116 (11.5)	118 (13.9)	117 (11.7)	𝐹<1
Forward digit repetition	3.6 (0.6)	3.7 (0.7)	3.8 (0.8)	𝐹<1
Backward digit repetition	2.9 (0.6)	2.8 (0.8)	2.8 (0.7)	𝐹<1
Trail-Making Test A	35.4 sec (10.7)	39.2 sec (12.3)	36.4 sec (8.2)	𝐹(2, 102) = 1.2, 𝑃=.30
Trail-Making Test B	93.9 sec (24.5)	96.3 sec (40.5)	97.4 sec (36.3)	𝐹<1
