You might have already heard the discombobulating fact that some peopledon’t have an internal monologue(or if you ’re an abstract mind , that some peoplethink with words ) . To tot up to the puzzling list of thing some people ’s brain do that others do n’t is a condition called aphantasia - the unfitness to visualizemental mental image .
Think of a click , explain it to me - large or modest ? Fluffy or short hair ? What color is it ? If you could see what you were describe in your “ mind ’s eye ” , you do n’t have aphantasia . If you ’re incompetent of picturing things in your psyche , then it ’s potential you could sit down within the two - to - five percentage of the people who areunable to form mental images .
Previous study have link aphantasia to patterns seen in other cognitive processes , like remembering , woolgather and imagining . Most enquiry into the unusual condition has bank on behavioral studies , but new enquiry published inProceedings of the Royal Society B , used an objective measure of cutis conductance to see how the ability to imprint mental images - or the deficiency thereof - alter people ’s reactions to show or looking atscary storiesor images .
Using 46 participant ( 22:24 aphantasia vs not ) , they first investigated the role of mental imagery in fear by flog electrode to the participants ’ skin . This method is commonly used in psychology inquiry to obtain data about worked up nation as skin becomes a better conductor of electrical energy when people are panic-struck or in hurt . The researchers then switch off the light and left the way , as the participant read write accounts of scarey story . Traumatic scenario included falling off a cliff , being chase by a shark or ending up in a plane that ’s about to crash .
“ Skin conductivity levels apace started to grow for people who were capable to visualise the taradiddle , ” said Professor Joel Pearson , older author on the paper and Director of UNSW Science ’s Future Minds Lab , in astatement . “ The more the narrative went on , the more their tegument react . But for the great unwashed with aphantasia , the peel conductivity levels middling much flatlined . ”
To eliminate personal thresholds for fear and distress , they repeat the experimentation with the same participant , but this clip show up distressing image instead of Logos – like picture of cadavers or a snake about to excise . There was to be no flatlining in this experimentation , as the picture successfully scared the dirt out of everyone regardless of whether or not they had aphantasia .
The results highlight the polar role of genial imagery in our emotional response to scary stories or distressing account statement from tragic events . Even the most harrowing of scenario fail to get much of a procession out of participants with aphantasia equate to those with the capacity to form genial images , but this was n’t because they as individual were plainly resistant to veneration .
“ We found the stiff grounds yet that genial imagery plays a primal role in associate thoughts and emotion , ” said Pearson . “ In all of our inquiry to date , this is by far the big difference we ’ve found between people with aphantasia and the general universe .
“ These two sets of resultant suggest that aphantasia is n’t linked to rock-bottom emotion in general , but is specific to participants reading scary chronicle . The worked up fear reception was present when participants actually saw the scarey material play out in front of them … Imagery is an worked up cerebration amplifier . We can reckon all variety of thing , but without imagery , the opinion are n’t going to have that aroused ‘ gravy ’ . ”
