Snake or Mammal Predator : For Which Is the Response Most Speeded In Visual Search? (English)
Abstract [sv]

Fyrtio deltagare fick som uppgift att genom ett visuellt avsökningsexperiment, så kallat visual search, avgöra om alla bilder i 3 x 3 matriser kom från samma kategori av djur eller om det fanns med någon bild från en avvikande kategori. Studiens syfte var att studera huruvida deltagarnas reaktionstider inför målbilder av ormar skilde sig från målbilder av stora rovdjur: björnar och vargar. Dessutom undersöktes om bilder i gråskala resulterade i snabbare, långsammare eller lika snabba responser som bilder i färg. Kortare reaktionstider observerades för målbilder av ormar än för björnar och vargar. Ormar skattades dessutom som mer obehagliga. Ingen skillnad observerades mellan bilder i gråskala och färgutförande. Detta kan bero på att inga neutrala stimuli, som växter, fanns med, utan bara djur, och att försöksdeltagarna därför fick förlita sig på föremålens form istället för färg.

Abstract [en]

Forty participants were given a visual search task of deciding whether all the pictures in 3 x 3 search arrays were from the same animal category or if they contained a picture from a deviant category. The purpose of the study was to examine the participant's reaction times to see if they differed between target pictures of snakes compared to bears and wolves, and to analyze if there were any differences in reaction times between a version in greyscale and a color version. Shorter reaction times were observed for target pictures of snakes compared to bears and wolves. Snakes were also estimated as more unpleasant. However, no differences in reaction times were observed between the version in greyscale and the color version. This might be caused by the fact that the current study did not contain any neutral stimuli, like plants, but only animals, and therefore the participants had to rely on the shape of the objects instead of color.
