Abstract (Swedish)
Sättet som världen presenterar sig för våra sinnesorgan är genom en kontinuerlig ström av information, men vår upplevelse av den är uppdelad i diskreta händelser. Enligt eventsegmenteringsteorin är den här segmenteringen en inbyggd och automatisk del av mänsklig kognition. Omfattande forskning ger inte bara stöd åt den här teorin utan tyder också på att sättet vi delar upp händelser påverkar vårt minne: vid test av ihågkomst och igenkänning presterar deltagarna bättre när informationen presenterats vid en händelsegräns. Den här studien syftade till att reproducera dessa tidigare resultat och att vidare undersöka ifall händelsegränser hänger ihop med att händelser upplevs vara längre. Vår hypotes var att objekt som visas vid en... (More)

Den här studien syftade till att reproducera dessa tidigare resultat och att vidare undersöka ifall händelsegränser hänger ihop med att händelser upplevs vara längre. Vår hypotes var att objekt som visas vid en händelsegräns skulle kännas igen lättare samt att de skulle upplevts ha visats längre än de jämförande kontrollobjekten. Vi utförde ett experiment med upprepade mätningar som bestod av en inkodningsfas med visuellt stimuli och ett påföljande igenkännings- och tidsuppskattningstest. Inga statistiskt signifikanta resultat framkom för någon av hypoteserna. Detta kan möjligen bero på den relativt låga statistiska styrkan i studien samt vissa metodologiska brister. (Less)
Abstract
The world presents itself to our sense organs as a continuous stream of input, yet we appear to conceive experiences in terms of discrete events. According to event segmentation theory, this segmentation is an intrinsic and automatic component of human cognition. A considerable body of research provides evidence for this claim and suggests further that the way we segment events has consequences for memory: performance in recall and recognition tests is superior for information made available at event boundaries. The present study was set out to reproduce these previous findings and to further explore whether event boundaries are associated with an increase in the perceived duration of events. We hypothesized that event boundary objects... (More)

The present study was set out to reproduce these previous findings and to further explore whether event boundaries are associated with an increase in the perceived duration of events. We hypothesized that event boundary objects would be recognised more effectively and judged retrospectively to have been shown for a longer period of time than comparable control objects. We conducted a repeated measures experiment with healthy adult participants which consisted of an encoding phase involving visual stimuli and a subsequent task on object recognition and temporal estimation. No statistically significant effects in support of either hypothesis were observed. Possible explanations for the lack of statistically significant results are the relatively low statistical power of the study as well as certain methodological limitations. (Less)
