- Abstract (Swedish)
- Minnesintergration är en minnesfunktion som bidrar till kunskapsinlärning genom att kombinera information från överlappande event. Denna studie undersöker påverkan av olika källor, ingrupp och utgrupp, på minnesintegration. Deltagarna (N = 61) valde medlemmar till sitt eget lag, ingruppen, och motståndarlaget, utgruppen. Medlemmar från båda lagen presenterade information till deltagarna genom ett “knowledge extension task”, baserat på mekanismer av minnesintegration. I inkodningsfasen lärde sig deltagarna fakta som presenterades av antingen en ingrupps- eller utgruppsmedlem, som de sedan kunde bilda “novel integration facts” från. I testfasen presenterades deltagarna för antingen en sann eller falsk version av dessa fakta, som de ombads... (More)

I testfasen presenterades deltagarna för antingen en sann eller falsk version av dessa fakta, som de ombads att bedöma sanningshalten av. Svaren indelades i träffar, korrekta avslag, falska positiva och missar. Resultatet visade att träffar var lika vanligt förekommande oavsett vilken social grupp som presenterat faktan, medan falska positiva var vanligare för information som presenterats av ingruppsmedlemmar. Det var även svårare för deltagarna att urskilja träffar från falska positiva, och de var mer benägna att acceptera information från ingruppskällor oavsett om det var sant eller inte. Slutligen var resultaten för källminne insignifikanta, däremot fanns en tendens för deltagarnas källminne att vara bättre för ingruppen. (Less)
- Abstract
- Memory integration is a memory function that promotes knowledge acquisition through the combination of information across overlapping events. This study investigates the influence of ingroup and outgroup sources on memory integration. Participants (N = 61) selected ingroup teammates and outgroup opponents to present them information in a knowledge extension task, driven by memory integration mechanisms. In the encoding phase, participants learned paired stem facts that were either presented by an ingroup or an outgroup source, from which they could later infer novel integration facts. In the testing phase, participants were presented with either a true or false version of each novel integration fact, and asked to judge the veracity of... (More)

This study investigates the influence of ingroup and outgroup sources on memory integration. Participants (N = 61) selected ingroup teammates and outgroup opponents to present them information in a knowledge extension task, driven by memory integration mechanisms. In the encoding phase, participants learned paired stem facts that were either presented by an ingroup or an outgroup source, from which they could later infer novel integration facts. In the testing phase, participants were presented with either a true or false version of each novel integration fact, and asked to judge the veracity of these. Participants’ responses could be divided into hits, correct rejections, false alarms and misses. The results showed that the amount of hits were equal for information presented by both social groups, but false alarms were more common for information presented by ingroup members. Participants also had more difficulty discriminating hits from false alarms, and were more likely to accept information presented by ingroup sources, irrespective of its actual veracity in the ingroup condition. Finally, the results on source memory were insignificant, although there was a tendency for participants’ source memory to be better for ingroup members. (Less)
