Theory 86/Mind wandering/Threshold lens
It Needs a Goal Threshold
The claim
Mind wandering requires a threshold in goal commitment, so a weakly held goal permits more off-task thought at the same task demand.
01Mechanism
Off-task thought competes with the current goal; the threshold determines whether the goal holds attention.
02Prediction
Wandering should track commitment.
03Refutation
Wandering tracking task demand would remove commitment.
