Abstract [en]

Earlier studies suggest that emotion affects long duration estimates of 3-7 seconds and more, but how emotions affect shorter events is not well known. The aim of the thesis was to investigate how emotion, in terms of emotional Valence and Arousal, affects subjective time estimates of short (sub-second) and long (half-a-minute) durations. Participants (N= 26) were exposed to neutral and emotive video clips resembling the International Affective Picture System (IAPS; Bradley, 1995) while making time discrimination judgments (short duration estimates: PSE). Afterwards they made long duration estimates (Long Time Estimates: LTE) and ratings of Valence and Arousal of every video clip. Significant results were that Arousal affected LTE estimates, with longer LTE estimates, the higher the Arousal level. The results indicate that Arousal, but not Valence, affects subjective time perception both of short and long durations.


Abstract [sv]

Tidigare studier antyder att emotioner påverkar uppskattningen av långa durationer på 3-7 sekunder, men hur emotioner påverkar kortare durationer är mindre känt. Studiens syfte var att undersöka hur emotioner, i form av emotionell Valens och Arousal, påverkar subjektiva tidsestimat av korta (sub-sekund) och långa (halv-minuts) durationer. Deltagare (N= 26), exponerades för stimuli i form av neutrala och emotionellt laddade videosekvenser utvalda att efterlikna the International Affective Picture System (IAPS; Bradley, 1995) och utförde samtidigt intervalldiskriminationer (korttidsestimat: PSE). Efteråt utförde de långa durationsestimat (långtidsestimat: LTE) och skattningar av Valens och Arousal för samtliga videoklipp. Signifikanta resultat var att Arousal gav längre durationsskattningar för LTE estimaten, med längre LTE estimat, ju högre Arousal-nivå. Resultaten indikerar att Arousal, men inte Valens, påverkar subjektiv tidsuppfattning för både korta och långa durationer.
