Abstract [en]

Previous research has shown that there are several components involved in how we perceive pain, e.g. social and psychological factors such as expectations of pain. A cold pressor experiment was conducted to investigate the impact of negative/positive information on pain perception. We also investigated if a cognitive conflict created by disconfirming information of a pain expectation influences the pain experience. 106 participants (49 men and 57 women) got to hold their hand in 5°C water for 1 minute. The main outcome variable was self-reported pain during the cold pressor test. The results show that participants receiving negative information perceived more pain than the group receiving positive information. There was no significant difference in pain perception between those who were confirmed or disconfirmed in an expectation, nor was there a difference in cognitive conflict between the two groups. This is a first attempt to explore pain and cognitive conflict and can work as an inspiration for further investigation.

Abstract [sv]

Tidigare forskning har visat att det är flera komponenter involverade i en smärtupplevelse, bland annat sociala och psykologiska faktorer så som förväntningar. Ett kallvattenexperiment utfördes för att undersöka positiv/negativ information och dess påverkan på upplevelsen av smärta. Vi undersökte även om smärta påverkas av en kognitiv konflikt skapad av en disconfirmation av en smärtförväntning. 106 deltagare (49 män och 57 kvinnor) fick hålla sin hand i 5°C vatten i en minut. Vårt mätinstrument var själv-rapporterad smärta vid kallvattentestet. Resultatet visade att deltagare som fick negativ information upplevde mer smärta än de som fick positiv information. Det fanns ingen signifikant skillnad mellan de som blev disconfirmed och confirmed i sin förväntan och inte heller någon skillnad mellan grupperna i upplevd kognitiv konflikt. Detta första försök att undersöka smärta och kognitiv konflikt kan bli till en inspiration för vidare undersökningar.
