- The objectives in this paper were to analyse noise effects on episodic and semantic memory performance in different age groups, and to see whether age interacted with noise in their effects on memory. Data were taken from three separate previous experiments, that were performed with the same design, procedure and dependent measures with participants from four age groups (13-14, 18-20, 35-45 and 55-65 years). Participants were randomly assigned to one of three conditions: (a) meaningful irrelevant speech, (b) road traffic noise, and (c) quiet. The results showed effects of both noise sources on a majority of the dependent measures, both when taken alone and aggregated according to the nature of the material to be memorised. However, the noise effects for episodic memory tasks were stronger than for semantic memory tasks. Further, in the reading comprehension task, cued recall and recognition were more impaired by meaningful irrelevant speech than by road traffic noise. Contrary to predictions, there was no interaction between noise and age group, indicating that the obtained noise effects were not related to the capacity to perform the task. The results from the three experiments taken together throw more light on the relative effects of road traffic noise and meaningful irrelevant speech on memory performance in different age groups.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Etter 10 år som et forsøk/prosjekt har EiNa endelig fått sin permanente organisering gjennom en partnerskapsavtale. EiNa-partnerskapet har nå medlemmer som dekker det meste av helseog sosialtjenestene i Namdalen. I tillegg er også oppvekstsektorens ansatte tatt inn i målgruppen for EiNas aktivitet. Denne rapporten er del 2 i det evalueringsprosjektet som styret i EiNa initierte i 2009 og som ble gjennomført av Høgskolen i Nord-Trøndelag. Del 1 presenterte virksomheten gjennom 10 år dels som en historiefortelling, dels med dokumentasjon av prosess og avtaler som EiNa er bygd opp omkring og dels gjennom å presentere aktiviteten i oversikter og i statistikk. Denne rapporten tar for seg resultatene av en brukerundersøkelse som ble gjennomført våren 2009.

Tidskriftsartikel (refereegranskat)abstract
- Competing models of declarative memory were tested with structural equation models to analyze whether a second-order latent variable structure for episodic and semantic memory was invariant across age groups and across noise exposure conditions. Data were taken from three previous experimental noise studies that were performed with the same design, procedure, and dependent measures, and with participants from four age groups (13-14, 18-20, 35-45, and 55-65 years). Two noise conditions, road traffic noise and meaningful irrelevant speech, were compared to a quiet control group. The structural models put to the test were taken from Nyberg et al. (2003), which employed several memory tests that were the same as ours and studied age-groups that partly overlapped with our groups. In addition we also varied noise exposure conditions. Our analyses replicated and supported the second-order semantic-episodic memory models in Nyberg et al. (2003). The latent variable structures were invariant across age groups, with the exception of our youngest group, which by itself showed a less clear latent structure. The obtained structures were also invariant across noise exposure conditions. We also noted that our text memory items, which did not have a counterpart in the study by Nyberg et al. (2003), tend to form a separate latent variable loading on episodic memory.
