Abstract
Retrieval-induced forgetting (RIF) refers to a memory phenomena where retrieval of a memory in some cases can deteriorate and affect the accessibility of related memories. A prominent explanation is presented in the inhibitory theory where active inhibition is considered to cause RIF by facilitating retrieval of a target memory among competing memories in selective memory retrieval. If exertion of inhibition leads to reduce RIF due to reduction of the facilitating function of the inhibitory mechanism, it would be a strong support to the idea that inhibition conduces RIF. Forty university students carried out either a demanding or a non-demanding version of an experiment prior to a final RIF test. Comparisons were made between control and... (More)

The experiment managed to induce a reliable RIF effect that was significant in the baseline version, but did show a tendency consistent with the hypothesis in the fatigue version. (Less)
Abstract (Swedish)
Retrieval-induced forgetting (RIF) beskriver ett minnesfenomen där framplockningen av ett visst minne i vissa fall försämrar och påverkar tillgängligheten till andra, relaterade minnen.
En framträdande förklaring har presenterats inom inhibitionsteori där aktiv inhibering anses orsaka RIF, genom facilitering i framplockningen av målminnet bland konkurrerande
minnen i selektiv minnesframplockning. I studien undersöktes hur RIF påverkas av att inhibition belastas med kognitivt krävande uppgifter. Om en belastning av inhibition leder
till minskad RIF på grund av nedsättning av mekanismens faciliterande funktion, skulle det vara ett starkt stöd för att inhibition bidrar till RIF. Fyrtio universitetsstudenter genomförde

till minskad RIF på grund av nedsättning av mekanismens faciliterande funktion, skulle det vara ett starkt stöd för att inhibition bidrar till RIF. Fyrtio universitetsstudenter genomförde
en antingen belastande eller icke belastande uppmärksamhetsuppgift före framkallning av RIF effekt. De huvudsakliga fynden i studien gav delvis stöd för hypotesen. Experimentet lyckades inducera en reliabel RIF effekt som var signifikant i kontrollbetingelse men minskning endast som tendens i riktning med hypotesen i belastningsbetingelse. (Less)
