Functional connectivity also differed between the tasks: Compared with semantic pairing, colour pairing relied more upon the inferior frontal gyrus, a key node of the control system, driving enhanced connectivity with occipitotemporal 'spoke'spoke
The programme recorded reaction time and accuracy and the task, with between-block breaks, took approximately 20 minutes.
Importantly, a significant three-way interaction was also obtained (task condition × hemisphere × cued direction: F 2,34) = 14.6; p < .001; ε = .918), suggesting that there were systematic differences in LDAP amplitudes between the three tasks, with larger LDAP components in the Covert and Combined tasks relative to the Saccade task (see Figs. 2 and 3).
This difference is particularly visible in Figure 2. A difference in cue-P3 amplitude between the tasks was significant, with both groups showing a decrease in amplitude in the CPT-OX [z = -3.39, p = 0.001, d = 0.46].
Interestingly, between-group differences in tasks with eyes closed and/or unstable surface are higher than those differences observed in the task with eyes open on stable surface.
In the current study, there was a significant correlation between the performance in the balance tasks with the eyes closed and the number of falls.
However, a significant difference emerged between the tasks [z = -2.48, p = 0.01, d = 0.33], with both groups showing an increase in amplitude in the flanker version.
On half of the trials, the relationship between the task-irrelevant parts was congruent with that of the task-relevant parts, and on the other half the relationships were incongruent.
However, until there is a confrontation between both tasks with the same subjects, this conclusion remains to be confirmed.
Each square represents the behavioral distance between pairs of tasks with a simple rule: the darker the square, the smaller the distance.
