The effect on recall of semantic categorized words (English)
Abstract [sv]

Den här studien grundar sig på skillnader mellan återgivning av ord, sorterade efter semantiska kategorier, i förhållanden med rent tal och maskerat tal. 32 personer deltog i studien där de först blev visuellt presenterade för en lista med 15 semantiska ord som skulle memoreras och sedan återges i fri ordning i två olika betingelser av bakgrundsljud, tal och maskerat tal. Utifrån tidigare studier utformades studiens hypoteser; vid återgivningen ökar antalet visuellt presenterade ord när bakgrundstalet maskeras av ett brus jämfört med när bakgrundstalet spelas upp utan maskering. Antalet auditivt presenterade ord som återges minskar när bakgrundstalet maskeras av ett brus jämfört med när bakgrundstalet spelas upp utan maskering. Resultaten gav stöd åt hypotesen att försökspersonerna återgav fler visuellt presenterade ord när bakgrundstalet maskerades av ett brus. Resultatet gav stöd åt hypotesen att försökspersonen återgav färre auditivt presenterade ord när bakgrundstalet maskerades av ett brus.

Abstract [en]

This study examined free recall performance in two acoustic conditions, speech and masked speech. Thirty-two students participated in the study. They were visually presented to word lists that were constructed by semantic similarity. After presentation the participants were instructed to recall as many words as possible in free order. The recall session occurred in the two different speech conditions. Based on earlier studies two hypotheses were stated; when the background speech were mixed with masking noise, recall performance of correct words would increase compared to the speech condition. It was also assumed that the masking noise would decrease the number of intrusions from the speech, compare with the number of intrusions made in the unmasked speech condition. The result gave support to the hypothesis that number of correct words increases in masked speech and the number of intrusions decreases in masked speech.
