Look into my eyes: Pupillometry reveals that a post?hypnotic suggestion for word blindness reduces Stroop interference by marshalling greater effortful control

The mechanisms underpinning the apparently remarkable levels of cognitive and behavioural control following hypnosis hypnotic suggestion are poorly understood. Numerous independent studies have reported that Stroop interference can be reduced a post-hypnotic asks participants to perceive words as if made up characters from foreign language. This effect indicates frontal executive functions more potent than is generally accepted has been described resulting top-down not normally voluntarily available. We employed eye tracking pupillometry investigate whether results voluntary visuo-attentional strategies (subtly looking away word prevent optimal processing), response conflict but overall conflict, effects being pushed selection execution (response durations) or increased proactive effortful given enhanced contextual motivation (as indexed via pupil dilation). replicated reduction in despite removing any trials on which movements were consistent with processing. Our data inconclusive regards type affected by latency data, although preserved semantic was evident data. There also no evidence durations. However, we show baseline-corrected sizes larger indicating socio-cognitive context experimental demands motivate marshal greater control.
