"Isolation and silence has never solved conflict," he said in a press release defending his trip.
This increased activation was equally clear for correctly and incorrectly solved conflict problems.
In their study participants solved conflict and no-conflict versions of the base-rate problems (and related syllogistic reasoning problems).
We also repeated the above analysis but made sure to exclude confidence ratings for correctly solved conflict trials.
In the present study we were less concerned with confidence ratings for correctly solved conflict problems per se.
To eliminate such a possible confound we ran a separate analysis that was restricted to confidence ratings for incorrectly solved conflict problems.
Results showed that we found the same 10% confidence decrease for the incorrectly solved conflict problems as in the overall analysis, F 1, 230) = 59.35, p<.0001, η2p = .21.21
As in Experiment 1, the between-subject confidence contrast on the first item was not significant for the correctly solved conflict items, F 1, 89) = 1.77, p = .19.19
As in Experiment 1, this effect was equally clear when the analysis was restricted to incorrectly solved conflict trials, F 1, 106) = 13.72, p<.0005, η2p = .12.12
